    Revisiting Terrain Collisions

    It's been a while since my last blog entry as I haven't had much time to work on my game due to work, chores, Christmas and... err... Red Dead Redemption 2 😂. I have only managed to do little bits here and there over the past couple of months but decided to spend some time revisiting my codebase and refactoring much of it. I had a Terrain object which handled the rendering of the terrain, the ocean AND the terrain collision geometry. It was starting to feel crowded in there and I was just being lazy lumping it all into one class! So I've split out the collision geometry into a separate 'class' - TerrainCollisionBody. This also helps with what I wanted to do next... Up until now I have just been loading the collision geometry for the entire map into memory on initialisation (at this point in time it's 1,048,576 vertices but that may indeed grow considerably in the near future) which was eating up a lot of memory... at one point prior to a few optimisations it seemed to be using over 1GB of memory!! My intention was always to stream the collision geometry in from the Node.js server via a simple API; nothing amazingly clever but just loading chunks/quadrants in when the player moves towards the edge of the current quadrant and unloading any quadrants that we no longer need. So I finally completed this feature yesterday! Yippee! The memory usage has now hugely dropped down to a far more reasonable level of just over 100MB (dependent on how many quadrants are loaded) and of course it now loads far, far faster! The Approach On the server side I have a simple end point that returns the collision geometry as a simple JSON object. This consists of two arrays, one for vertices and one for faces. Each element in the faces array contains three indices which point to elements in the vertices array and a Vector3 which describes the pre-calculated face normal. The end-point takes parameters for the X and Z co-ordinates of a point on the map and a 'view size' - this determines the size of a square around the player for which it should load a subset of the collision geometry. On the client side I use the player position to determine which quadrants I need to load. This could be more than 1 quadrant since if the player is near a quadrant boundary I want to pre-load any applicable surrounding quadrants to create a seamless transition as the player steps into new quadrants. For example, in the diagram below, if the player is in the centre of a quadrant (the red X) then I'd only need to load the quadrant the player is in (unless it's already been loaded and then I do nothing of course)... If the player moves within a certain distance of the quadrant boundary then we could potentially need to pre-load up to 3 quadrants. e.g. The yellow areas represent the quadrants to load. I'm sure you get the idea by now so I won't go on. Once I've determined the quadrants I need to load all I have to do is determine the centres of each quadrant and request the collision geometry via the Node.js end-point. e.g. /api/terrain/collisiongeometry/get/-3072/7168/2048 ... where -3072 and 7168 are the X and Z co-ords of the centre of a quadrant (map centre is 0,0). The results are stored in an array of quadrants, each quadrant being an object containing all the vertices and faces for that quadrant. Any quadrants that are no longer required are deleted from the array to free up memory. I hope this makes sense to someone other than me. 😂 Anyway, the result is pretty smooth so far! The only other thing to mention is that I only do the quadrant check once every 10 seconds since doing it every frame seemed unneccesary and the more milliseconds per frame I can free up for more frequent stuff the better. I think for my next task I'll start adding in a few static objects to the terrain (buildings etc) to make it more interesting. Then I think I may get what I have so far on a public facing server so other people can have a play around with it (hopefully).

  4. So I have a decent amount of JavaScript experience now and decided I was gonna lower my head and start cranking out some 2d games, partly to learn, partly to have fun. Afterall, HTML5 canvas is such an easy and enticing medium. I love the JavaScript implementation of it. But after literally struggling for a week to get basic game functionality working I have had enough of the little stupid bugs that pop up with JavaScript. Don't get me wrong, I still love the language for scripting. I'm just not going to spend 20 mins coding and 5 hours debugging just because the language is crap. I've decided to return to my previous endeavor, Java. I like Java a lot and the only reason I haven't pursued more in the way of game development is just for the fact that Java is limited to mobile or PC apps that may never see the light of day unless it's hosted on some obscure Java game hosting website that is populated with 2,000 half developed games that no one will ever care about. BUT, still, I enjoy hand coding and I know C# but don't feel like using Visual studio and I really don't wanna hand code C# on the .Net or whatever. I use Visual Studio for business apps (ASP.NET) but I don't wanna build a game with it. So, does anyone have any points to share about why moving to Java for game development is not smart? Besides the whole, "Java is slow" thing. I mean things that might make it harder in JAva to make games vs. in other languages. Please share your thoughts.
  5.

  6. Hello everyone, in the game code below (written using the Phaser framework) I am trying to pass the variable this.inputScore to the global function assignValue. How can I do this? The assignValue function is being read by an external Index.html file on game over and I need this.inputScore to be passed to the Index.html file. I would greatly appreciate any help - new to programming. Thank you. //GLOBAL FUNCTION function assignValue() { document.getElementById("inputScore").value = this.inputScore; //how can I get this.inputScore from the game code below? }; //GAME CODE var CrystalRunner = CrystalRunner || {}; CrystalRunner.GameState = { init: function() { //...code here }, create: function() { //...code here }, update: function() { //..code here //check if the player needs to die if( >= { this.gameOver(); } }, gameOver: function(){ //..code here this.updateHighscore(); //..code here }, updateHighscore: function(){ this.highScore = +localStorage.getItem('highScore'); if(this.highScore < this.myScore){ this.highScore = this.myScore; this.inputScore = this.highScore; //I need this.inputScore to be passed into the assignValue function this.submitScoreButton =,, 'submitScoreButton'); { window.location.href = "index1.php"; //Index1.php will have a form input value into which this.inputScore will be passed }, this); } localStorage.setItem('highScore', this.highScore); }, };
  7. I am designing a very simple 2d tilemap engine with HTML5 canvas and Javascript. I have two for loops to run through map coordinates and then draw to canvas a tile based on what the said coordinate value is. While doing this, I also need to able to assign an incrmenting var/class/type or whatever with dynamic parameters such as that tile's x, y, and number values. Something like the following pseudo theory: for loop ++ , for loop++ counter++ sprite[counter]{ x=someNum; y=someNum; value=someVal; } Thanks for any help! Jscript_GameTest.html
  8. Hi everyone. For the last few months I’ve been working on a simple HTML5 2D side scrolling action game called Theraxius. It's nothing new and revolutionary, it's more like an evolution of different technology (combination of HTML5, PHP, MySQL). The game also includes a level editor so you can create your own levels. The game and the level editor is written almost completely in JavaScript, no download is required. Just load and play. Here are a few screenshots and the link to the page. In the next weeks I’ll try to post some videos, try to add registration (for newsletter and later for public test). Release date: when it's done
  9. Looking for a developer to help me develop a bot for discord, it will be a few simple features that will all work together to create a bot perfect for Discord servers that want to be used for games. I am creating a server for Halo Infinite competitive play and need something to fit the purpose, but I want the bot to be multipurpose and work on other servers for different games. The features i want it to have are: - Auto Roles, controllable by admin of how they are given, so if admin accepts them they get given a specific role. - Basic announcement commands - Nickname requester - auto message when specific command is made e.g. when i use a specific reaction to a message, I can automate a new message. - Welcome messages, leave messages etc... - I want a way to organise teams in roles, but I want their team captain to choose who has that role so I want specific people to be able to give the team role to people or request a role for someone if the other isn't possible. -A ban, unban, report system etc. - Chat command purge, so when a command is used or a specific reaction etc... the chat is cleared for that person to keep the chats tidy. -Maybe a way for messages to be moved into a different chat almost copy and pasted, so if a user requests to change their nickname in one chat the request goes to a private chat for the admins, so the public chat stays clear. Extra Features if possible: - Event reminders for when there are matches etc... sent to team captains when they have a scrim match - Leveling system but given by the admins, this can be when they win matches, or tournaments they level up on the admins command, this will then categorise the roles. -A way to search for certain roles so for example search for all of the players with a specific role(rank), specified by the admins so they can recruit players etc... and also a way to search for a certain players username and find out what rank they are in your server. - A twitch broadcasting automation set by admins for when a specific matchup is being streamed and this gets posted wherever specified maybe announcements etc... Future Preferences: -A way for people to get involved like a in discord currency everyone is given a specific amount when they start and they then can use that to gain currency by predicting who is going to win/draw, so they place the currency on specific result, result is posted by admins and the total amount of currency used is split between the people that won etc... There will be in discord leaderboards for people with the most currency, there will be prizes for people with the most currency by the end of each month or so... they will also be able to donate to the channel, and will receive bonuses in the channel. -Depending on how much is donated to the channel, they can work up tiers, if they donate £10 for example they get priority status on twitch links and when they start to stream they are auto posted in the twitch channel. etc... -got more ideas,

    Frameworks, tooling and other drugs

    It's been long since some colleagues and me "achieve" our unfinished Red Atlas I project. A full hackaton weekend trying to do a strategic game and the full weekend deep inside PhaserJS, our bet on free game frameworks and engines. Phaser 2 CE & Webpack 3 I liked Phaser framework and I wanted to come back to this framework, so now here I am again, working with an idea of #isometric #RPG. Well, not now, Phaser released its 3.x version and webpack is in its 4.x version. I started this idea some time before, using Phaser 2 CE and Webpack 3.x and it looks like is not easy to migrate to Phaser 3 now for me. The future will say... As I re-started this idea many times searching for a good architectural approach to work with this toolchain I decided recently to upload and share the boilerplates I used to start. I hope it helps someone! Boilerplate for 2D games Boilerplate for Isometric games

    State Changes

    Games usually (if not always) require some way to manage state changes... and I'm sure most of you (if not all of you) know far more about State Machines than I do. And I'm certain that I could learn a heck of lot from reading up about the subject to build a state machine that works beautifully and makes my code look amazing etc etc. Pfft.. never mind all that... I'm building this game 'off the cuff' as it were, making it up as I go along and following the principle of 'I build what I need when I need it and only insofar that it adequately fulfils the requirements at that time'. I don't try to plan ahead (not in any granular sense anyway), I'm not building a reusable one-size-fits-all game engine, I'm not trying to make the code beautfiul, or win any awards or even make any money from the darn thing. It just needs to perform well enough for what I want it to do. So my immediate requirement is that I have a way to manage the player switching from walking to running to whatever. If I can use it elsewhere for other things then great... and I'll be honest, I do like reusable code so I tend to naturally sway toward that. What I'm trying to avoid is getting myself stuck in a rut, spending weeks/months deliberating over the smallest details because it's got to be 'perfect' and then realising I've still got 99.5% of the game to build! Quick and dirty is OK in my world. I often approach things from a top-down perspective. This boils down to: 'How do I want to instruct the computer to do x, y or z?' So for this particular requirement, how do I want to instruct the game that the player can change from walking to running and running to walking, or walking/running to falling (assuming I make that a player state - which I do), but not from sleeping to running for example? Hell, I don't even know all the states that I want yet, but these are the ones I have a feel for so far: Walking Running Skiiing Driving Falling Drowning Sleeping Eating Introducing 'When' I thought it might be nice to be able to write something like this in my player setup: // Configure valid player state transitions When( this.playerState ).changes().from( PLAYER_STATES.WALKING ).to( PLAYER_STATES.RUNNING ).then( function () { } ); When( this.playerState ).changes().from( PLAYER_STATES.RUNNING ).to( PLAYER_STATES.WALKING ).then( function () { } ); When( this.playerState ).changes().from( PLAYER_STATES.WALKING ).to( PLAYER_STATES.SKIING ).then( function () { } ); When( this.playerState ).changes().from( PLAYER_STATES.SKIING ).to( PLAYER_STATES.WALKING ).then( function () { } ); When( this.playerState ).changes().from( PLAYER_STATES.WALKING, PLAYER_STATES.RUNNING, PLAYER_STATES.SKIING ).to( PLAYER_STATES.FALLING ).then( function () { } ); There's probably a library for something like this out there, but heck, where's the fun in that?! So I create a new 'Stateful' object that represents a state (in this case the playerState) and it's allowed transitions and a 'When' function so I can write the code exactly as above: const Stateful = function () { } Stateful.isStateful = function ( obj ) { return obj.constructor && ===; } Stateful.areEqual = function ( v1, v2 ) { return v1.equals ? v1.equals( v2 ) : v1 == v2; } Stateful.prototype = { constructor: Stateful, set: function ( v ) { let newState = typeof ( v ) === "function" ? new v() : v; for ( let i = 0; i < this.transitions.length; i++ ) { let transition = this.transitions[i]; if ( transition && typeof ( transition.callback ) === "function" ) { let fromMatch = Stateful.areEqual( transition.vFrom, this ); let toMatch = Stateful.areEqual( transition.vTo, newState ); if ( fromMatch && toMatch ) { // We can only change to the new state if a valid transition exists. this.previousState = Object.assign( Object.create( {} ), this ); Object.assign( this, newState ); transition.callback( this.previousState, this ); } } } }, transitions: Object.create( Object.assign( Array.prototype, { from: function ( vFrom ) { this.vFrom = typeof ( vFrom ) === "function" ? new vFrom() : vFrom; return this; }, to: function ( vTo ) { this.vTo = typeof ( vTo ) === "function" ? new vTo() : vTo; return this; }, remove: function ( fn ) { this.vFrom = this.vFrom === undefined ? { equals: function () { return true; } } : this.vFrom; this.vTo = this.vTo === undefined ? { equals: function () { return true; } } : this.vTo; for ( let i = 0; i < this.length; i++ ) { let transition = this[i]; let fromMatch = Stateful.areEqual( this.vFrom, transition.vFrom ); let toMatch = Stateful.areEqual( this.vTo, transition.vTo ); let fnMatch = fn === undefined ? true : transition.callback == fn; if ( fromMatch && toMatch & fnMatch ) { delete this[i]; } } } } ) ) } function When( statefulObj ) { if ( !Stateful.isStateful( statefulObj ) ) { throw "Argument must be a Stateful object"; } return { changes: function () { return { from: function ( ...vFrom ) { this.vFrom = vFrom; return this; }, to: function ( ...vTo ) { this.vTo = vTo; return this; }, then: function ( fn ) { if ( typeof ( fn ) === "function" ) { this.vFrom = this.vFrom === undefined ? [true] : this.vFrom; this.vTo = this.vTo === undefined ? [true] : this.vTo; for ( let i = 0; i < this.vFrom.length; i++ ) { for ( let j = 0; j < this.vTo.length; j++ ) { statefulObj.transitions.push( { vFrom: typeof ( this.vFrom[i] ) === "function" ? new this.vFrom[i]() : this.vFrom[i], vTo: typeof ( this.vTo[j] ) === "function" ? new this.vTo[j]() : this.vTo[j], callback: fn } ); } } } else { throw "Supplied argument must be a function"; } } }; } } } I drop the aforementioned 'When' statements into my Player setup and remove the old 'If' statements that were previously controlling changes between walking and running and insert the new playerState.set() calls where appropriate. e.g. "run": ( pc, keyup ) => { if ( keyup ) { _this.player.playerState.set( PLAYER_STATES.WALKING ); } else { _this.player.playerState.set( PLAYER_STATES.RUNNING ); } } And it seems to work! (Yes I was actually surprised by that) 😂 TheBerg-StateChanges.mp4 p.s. I've switched to using Bandicam for screen capture as it seems far superior to what I was using previously.

    Server(s) Side

    Hello GameDev, I've been busy working on Dynamic Assets. In order to successfully incorporate them this time around I've needed to include a whole host of programming across all the servers for this game and I thought 'why not do a blog about the servers'. I've never programmed a server before this project and really have no idea what I'm doing. I just get stuff working and I'm happy. But seems Node.js is very intuitive and it is so simple that you don't need to be a rocket scientist to figure stuff out. But a quick overview of my servers and why I have 3 so far and will probably have 5 or 6. Relay Server The relay server hosts the website and is responsible for user authentication and what-nots. While users are connected to the simulation the relay acts as a relay ( imagine that ) between all the clients and the back-end servers. It relies on to communicate with the clients and zeromq to communicate with the back-end servers. Data Server The data server holds a static version of the world and all it's contents. It's purpose is to provide all the information needed to a newly connected client. This way the demand for data isn't hampered by newly connected clients while the simulation is running. Of course it needs occasional updates and the terrain changes and the assets change. And soon too updated Simulin positions. Simulation Server This hosts the path-finding and tiny bits of user functionality that I've Incorporated thus far. But basically the simulation server is the work-horse behind the simulation, or at least will be. I plan on breaking this up into 3 separate servers. My wish list is to have 2 path-finding servers which each host world information necessary to path-finding and then requests are toggled between the two ( cut my pathfinding time in half ). And an AI server which will handle what it is the Simulin are doing. -------------------------------------------------- Now my assumption is that each new instance of a Node.js server will utilise it's own processing core? Am I wrong about this? I sure hope not because I figure that if I break the needs of the project over multiple servers it will make better use of a computers abilities. Maybe each Node.js server will operate in parallel? Because I'm using many different servers to do all the stuff I need to do it's taking a much longer time to program all this. Plus, I recently switched all my THREE.js geometry over to buffergeometry. The servers hold world data information according to vertex objects and face objects, but the clients hold world information according to buffer arrays which require a little trickery to update correctly. Keeps me on my toes. ----------------------------------------------------- Anyways, here's some video's to check out of my website And here is a video of three connected clients. One client is adding stuff to the world, the other two are receiving the updated content. from a different perspective. Thanks for checking it out!

    Slopey McSlopeface (part 2)

    Having played around with the character movement a bit more I realised I was doing many things wrong. Not that I had ever intended to do things perfectly, but the slope handling just wasn't up to scratch. I had acceleration working, but deceleration didn't due to the way I had built things. So I decided to do a little bit of an overhaul of the player movement system. Nothing too major it turns out but I now have both acceleration and deceleration working very nicely and it gives a much smoother feel to the controls. It's subtle but necessary in my opinion. There is one aspect of slopes that I haven't tackled yet though and that is falling, tumbling or sliding on steep slopes. As I'm not using any fancy physics engine my player character is essentially glued to the terrain like it's on rails. It's not really an issue in so far as jumping is concerned because I don't intend to have any jumping ability in the game. However, I decided that I didn't want to artificially prevent the player from walking off the edge of a cliff so I need some form of falling action (and tumbling if you run down a steep slope too fast - potentially injuring yourself). So what I've done is add forces into my CollisionBody class to represent an accelerant force due to gravity. But to keep my brain from imploding over the quirks of simulating physics (and so as not to have to implement a full-blown physics engine) I decided to half keep the on-rails aspect by doing this: if ( obj.collisionBody.position.y <= targetPos.y ) { obj.collisionBody.position.y = targetPos.y; obj.collisionBody.resetForces(); } else { // Apply gravity obj.collisionBody.applyForce( new Force( DEFAULT_VECTORS.down, _this.gAcceleration ) ); } Where 'targetPos' is the ground position. So if the player is in contact with the ground or moves below it, then they player will just snap back to the precise point on the terrain. It's only when the player goes above the terrain (into the air) that gravity comes into play. This helps keep things nice and simple and gives a nice feel to the movement. Oh and I've also added in some 'head-bobbing' to add a bit of realism to the movement. Overall it gives a really nice result.... and I can now fall off cliffs... You may also notice that the camera rotation is now much smoother too as I now 'slerp' between rotations rather than doing absolute movements, although my screen recording software doesn't do it justice in the video above.
  17. Dear members, I'm sorry to be asking in Javascript, but it is the only language I'm working with currently. I am hoping that the code is simple enough for you to understand what it is doing. I'm trying to rotate a cube so that dragging down always rotates the object around the world X axis, and dragging to the side always rotates the object around the world Y axis no matter the rotation of the object. I've seen this example which achieves the exact behavior I am looking for: And then, here's my jsFiddle code that I'm having trouble with: I saw this stackoverflow answer: But I still don't understand what I'm doing wrong. I think I'm still multiplying the rotation matrix to the left side of the object matrix in my code, but the object is always just rotating around its local axis. I learned how the transformation matrix works and how quaternion works but I feel like I am still missing something crucial here. I would really appreciate your help. Thank you.
  18. I am creating an endless runner, please see my code here: At the moment when the left arrow key is pressed the player moves left, the camera follows him so he does not go off screen and the ground tiles below the player are destroyed as they move out of the world bounds on the right and are recreated just before they move into the world bounds on the left. This allows him to keep running forever without running out of ground and works perfectly, but with one problem: I want the player to be running to the right of the game, NOT to the left. Please note I do not need the player to be able to move both ways. I can make the camera follow the player to the right instead of the left by doing the following: I remove the negative from -this in, 0, ...); so it becomes, 0, ...); Now when the right arrow key is pressed the camera follows the player as he runs right so he does not go off screen, but the ground tiles do not regenerate and he runs out of ground. So basically I need to reverse the direction in which the ground is regenerating but I can't figure out how to do it. As everything is working to the left, I am sure it's a few simple settings, perhaps some negatives that need to be made positive? I have tried all that I can think of but I can't get it to work. I think the key to solving this might be in these lines: this.platforms.forEachAlive( function( elem ) { this.platformXMin = Math.min( this.platformXMin, elem.x ); if( elem.x > + ) { elem.kill(); this.platformsCreateOne( this.platformXMin - 70, - 50, 50 ); } }, this ); I have tried changing all sorts of settings there, but I can't seem to get it to work. I am new to Phaser and still learning Javascript. Is anyone able to see an obvious solution? I'd be so grateful. Thanks in advance for any help!
  19. I have a background image and a separate ground image that I want to repeat as long as the character is moving forward. When the character stops, the background and ground should not be moving. Basically I am creating an endless runner. For similar games it is often suggested to add -= 1to the update function. This is not what I am looking for as it makes the background constantly move regardless of whether the character is moving. At the moment my background and ground images are repeating, but they are restricted to, 0, 1280, 800);. Any suggestions would be greatly appreciated as I have been at this for days, and I am sure there must be a simple solution. Please see my code below: function Hero(game, x, y) {, game, x, y, 'player'); this.anchor.set(0.5, 0.5);; this.body.collideWorldBounds = false; this.animations.add('stop', [0]); this.animations.add('run', [1, 2, 3, 4, 5], 14, true); // 14fps looped this.animations.add('jump', [6]); this.animations.add('fall', [7]); this.animations.add('die', [8, 9, 8, 9, 8, 9, 8, 9], 12); // 12fps no loop } Hero.prototype = Object.create(Phaser.Sprite.prototype); Hero.prototype.constructor = Hero; Hero.prototype.move = function (direction) { const SPEED = 200; this.body.velocity.x = direction * SPEED; if (this.body.velocity.x < 0) { this.scale.x = -1; } else if (this.body.velocity.x > 0) { this.scale.x = 1; } }; Hero.prototype.jump = function () { const JUMP_SPEED = 600; let canJump = this.body.touching.down; if (canJump) { this.body.velocity.y = -JUMP_SPEED; } return canJump; }; Hero.prototype.bounce = function () { const BOUNCE_SPEED = 200; this.body.velocity.y = -BOUNCE_SPEED; }; Hero.prototype.update = function () { // update sprite animation, if it needs changing let animationName = this._getAnimationName(); if ( !== animationName) {; } }; Hero.prototype.die = function () { this.alive = false; this.body.enable = false;'die').onComplete.addOnce(function () { this.kill(); }, this); }; Hero.prototype._getAnimationName = function () { let name = 'stop'; // default animation if (!this.alive) { name = 'die'; } else if (this.body.velocity.y > 0 && !this.body.touching.down) { name = 'fall'; } else if (this.body.velocity.y < 0) { name = 'jump'; } else if (this.body.velocity.x !== 0 && this.body.touching.down ) { name = 'run'; } return name; PlayState = {}; PlayState.init = function () { = true; this.keys ={ left: Phaser.KeyCode.LEFT, right: Phaser.KeyCode.RIGHT, up: Phaser.KeyCode.UP }; PlayState.preload = function () {'level:1', 'data/level01.json');'ground', 'images/ground.png'); // I need this to repeat infinitely'background', 'images/background.png'); // I need this to repeat infinitely'player', 'images/player.png', 64, 64); }; PlayState.create = function () {, 0, 1280, 800); =, 0,, 800, 'background'); =, 680,, 166, 'ground');; = true; = false; = Phaser.ScaleManager.SHOW_ALL; this._loadLevel('level:1')); }; PlayState.update = function () { this.physics.arcade.collide(this.player,; this._handleInput(); }; PlayState._handleInput = function () { if (this.keys.up.isDown) { this.player.jump(); } else if (this.keys.right.isDown) { // move player right this.player.move(1); } else if (this.keys.left.isDown) { // move player left this.player.move(-1); } else { // stop this.player.move(0); } }; PlayState._loadLevel = function (data) { this._spawnPlayer({player: data.player}); const GRAVITY = 1200; = GRAVITY; }; PlayState._spawnPlayer = function (data) { this.player = new Hero(, data.player.x, data.player.y);;, Phaser.Camera.FOLLOW_PLATFORMER); }; window.onload = function () { let game = new Phaser.Game(866, 520, Phaser.CANVAS, 'game'); game.state.add('play', PlayState); game.state.start('play'); };

  22. Hello. I'm trying to implement normal mapping. I've been following this: The problem is that my tangent vectors appear rather obviously wrong. But only one of them, never both. Here's my code for calculating the tangents: this.makeTriangle = function(a, b, c) { var edge1 = VectorSub(b.pos, a.pos); var edge2 = VectorSub(c.pos, a.pos); var deltaU1 = b.texCoords[0] - a.texCoords[0]; var deltaV1 = b.texCoords[1] - a.texCoords[1]; var deltaU2 = c.texCoords[0] - a.texCoords[0]; var deltaV2 = c.texCoords[1] - a.texCoords[1]; var f = 1.0 / (deltaU1 * deltaV2 - deltaU2 * deltaV1); var vvec = VectorNormal([ f * (deltaV2 * edge1[0] - deltaV1 * edge2[0]), f * (deltaV2 * edge1[1] - deltaV1 * edge2[1]), f * (deltaV2 * edge1[2] - deltaV1 * edge2[2]), 0.0 ]); var uvec = VectorNormal([ f * (-deltaU2 * edge1[0] - deltaU1 * edge2[0]), f * (-deltaU2 * edge1[1] - deltaU1 * edge2[1]), f * (-deltaU2 * edge1[2] - deltaU1 * edge2[2]), 0.0 ]); if (VectorDot(VectorCross(a.normal, uvec), vvec) < 0.0) { uvec = VectorScale(uvec, -1.0); }; /* console.log("Normal: "); console.log(a.normal); console.log("UVec: "); console.log(uvec); console.log("VVec: "); console.log(vvec); */ this.emitVertex(a, uvec, vvec); this.emitVertex(b, uvec, vvec); this.emitVertex(c, uvec, vvec); }; My vertex shader: precision mediump float; uniform mat4 matProj; uniform mat4 matView; uniform mat4 matModel; in vec4 attrVertex; in vec2 attrTexCoords; in vec3 attrNormal; in vec3 attrUVec; in vec3 attrVVec; out vec2 fTexCoords; out vec4 fNormalCamera; out vec4 fWorldPos; out vec4 fWorldNormal; out vec4 fWorldUVec; out vec4 fWorldVVec; void main() { fTexCoords = attrTexCoords; fNormalCamera = matView * matModel * vec4(attrNormal, 0.0); vec3 uvec = attrUVec; vec3 vvec = attrVVec; fWorldPos = matModel * attrVertex; fWorldNormal = matModel * vec4(attrNormal, 0.0); fWorldUVec = matModel * vec4(uvec, 0.0); fWorldVVec = matModel * vec4(vvec, 0.0); gl_Position = matProj * matView * matModel * attrVertex; } And finally the fragment shader: precision mediump float; uniform sampler2D texImage; uniform sampler2D texNormal; uniform float sunFactor; uniform mat4 matView; in vec2 fTexCoords; in vec4 fNormalCamera; in vec4 fWorldPos; in vec4 fWorldNormal; in vec4 fWorldUVec; in vec4 fWorldVVec; out vec4 outColor; vec4 calcPointLight(in vec4 normal, in vec4 source, in vec4 color, in float intensity) { vec4 lightVec = source - fWorldPos; float sqdist = dot(lightVec, lightVec); vec4 lightDir = normalize(lightVec); return color * dot(normal, lightDir) * (1.0 / sqdist) * intensity; } vec4 calcLights(vec4 pNormal) { vec4 result = vec4(0.0, 0.0, 0.0, 0.0); ${CALC_LIGHTS} return result; } void main() { vec4 surfNormal = vec4(cross(vec3(fWorldUVec), vec3(fWorldVVec)), 0.0); vec2 bumpCoords = fTexCoords; vec4 bumpNormal = texture(texNormal, bumpCoords); bumpNormal = (2.0 * bumpNormal - vec4(1.0, 1.0, 1.0, 0.0)) * vec4(1.0, 1.0, 1.0, 1.0); bumpNormal.w = 0.0; mat4 bumpMat = mat4(fWorldUVec, fWorldVVec, fWorldNormal, vec4(0.0, 0.0, 0.0, 1.0)); vec4 realNormal = normalize(bumpMat * bumpNormal); vec4 realCameraNormal = matView * realNormal; float intensitySun = clamp(dot(normalize(, normalize(vec3(0.0, 0.0, 1.0))), 0.0, 1.0) * sunFactor; float intensity = clamp(intensitySun + 0.2, 0.0, 1.0); outColor = texture(texImage, fTexCoords) * (vec4(intensity, intensity, intensity, 1.0) + calcLights(realNormal)); //outColor = texture(texNormal, fTexCoords); //outColor = 0.5 * (fWorldUVec + vec4(1.0, 1.0, 1.0, 0.0)); //outColor = vec4(fTexCoords, 1.0, 1.0); outColor.w = 1.0; } Here is the result of rendering an object, showing its normal render, the uvec, vvec, and texture coordinates (each commented out in the fragment shader code): Normal map itself: The uvec, as far as I can tell, should not be all over the place like it is; either this, or some other mistake, causes the normal vectors to be all wrong, so you can see on the normal render that for example there is a random dent on the left side which should not be there. As far as I can tell, my code follows the math from that tutorial. I use right-handed corodinates. So what could be wrong?

    My first RPG game in javascript

    Hello, i want to share my project with others just for not being the only person who knows about it I think i'm not completely beginner, so i decided to try some game. I'm still learning game mechanism so probably this project is for testing purposes. I started as a website developer so i am coding in javascipt. Of course i will learn new real programming languages like C++ or java but probably in near future. For now js is enough for me This is my first video from the game just to show features i've made. It was recorded some time ago, so there's more small features now, just need to record new video Please let me know what you think about it(don't look at rpg maker textures, it's for testing purposes, ofc in official release i will made my own txt) and what features would you like to see in the future. P.s: sorry for my bad english, i'm still learning(and for no HD in video ) Link to video(Youtube)
