1. Past hour

That's looking really great!! You should definitely start a project page/blog here(it's all available on gamedev.net), it's a great way to get some more feedback and have a central location to keep your updates if nothing else. Just click on Blogs or Projects from the home page and you should get the option to start a new blog or project respectively. A project page is just general information about your game/project, and a blog can be used to post updates about a project or anything on your mind really. Can't wait to see what you make!
3. ## Interpolation over Mesh

Yes, what you want is called a 'harmonic map' from given boundary vertices. To build the laplacian you need to calculate 'cotan weights' per edge to guarantee values propagate in equal quantities over all directions on the irregular mesh. Here is a tutorial that solves the problem with simple iterative method: http://rodolphe-vaillant.fr/?e=91, but you can also solve just one linear system per color channel. Notice that cotan weights do not work well if triangles contain angles much larger than 90 degrees. In practice you can mostly ignore this. Otherwise a solution is to flip edges until you get a proper delauney triangulation, or to modify weights (i remember a paper: 'HOT' method).
4. ## It's NOT a Simulation! :D

I think I've finally put my finger on the button(s)(quite a few apparently) that may explain my project. It's helping me to clarify my vision anyhow, so just play along okay? I'm not building a game simulation.... I've been trying to use that term because it's what everybody else uses, and it really just doesn't fit my project at all. There is no single starting point and there is no single ending point. The story elements are to be primarily interaction based and not strictly tied to highly specific locations or circumstances. The visual synchronicity of the experience is only dependent on entity proximity, which in effect makes it more of a relativistic kind of synchronicity than the absolute kind anyhow. All gaming entities(players,npcs,mobs,bosses..etc) will be autonomous actors in the gaming environment, regardless of what controls it. e.g. Each NPC will essentially be their own entirely isolated behavioral code(running on a server OR client node somewhere). This code will generate a game entity that is just as actualized in the environment as any other object or player character, it will just behave according to its "script". All in real-time, with client controlled physics. So, I'm building a "Multiple Entity Gaming Environment".... It's a working title.. In essence, instead of streaming data that has been aligned to a unified simulation out to many many clients, I'm streaming data about many many ongoing semi-synchronous real-time "INTERACTIONS" from game clients into a massive, fast, circular buffer. From which, the servers shall draw conclusions and route corrective actions to multiple endpoints simultaneously, and hopefully in many cases, preemptively. When we're worrying about things in a game becoming out of sync, it's usually in relation to some kind of fast motion or relative positioning, a gun-shot or a left hook, something that is moving/has moved/will move and the event needs to have the same outcome on multiple gaming clients. Users in most games with this kind of action, don't generally care if their team-mate was .5 meters closer to them then they looked like they were when they helped shoot down the boss. They only care that the shots they saw coming from that team-mates gun were hitting the mark that the team-mate was aiming at, which was hopefully the boss, if the team-mate is any good. This may be something of a contrived example, but it more or less illustrates my point. As long as the servers can provide the appropriate real-time adjustments to certain aspects of the entity interactions to make the synchronicity fall into a zone of acceptability, then nearly all the heavy lifting can be done by the client without running every client input into and back out of a tightly wound server controlled simulation. Then, how do we control anything? The major change here is how Authority is implemented, in a standard server-simulation, the policy is trust nobody. Here, it is trust everybody, but also verify and cross-check everything. In this paradigm the authority is purely corrective in nature, with designs on preemptive corrective abilities(where applicable), but primarily relying on minuscule corrective actions that steer the simulation variances into a zone of acceptability. Another fairly extensive level of control comes from the decoupled nature of the system. Since all entities are autonomous components, they can each be turned on or off at will. So, that pretty much gives us all the control, never heard of before. Each entity can be rewritten, debugged, uploaded and instantiated into the game. Without a single system restart, or change to the game code(goals, I got em). So, since we aren't wasting all of our server horsepower on a massive interactive simulation, we can use it to play cop, crossing-guard, mail-carrier and chauffeur all at once. We can implement heavy-handed position and relative distance checking into the entity data feeds that are being streamed INTO the servers, we can correlate those patterns with known good behaviors and known cheat behaviors/known out of bounds behaviors. We can implement corrective actions that will steer the entities back into synchronous path(s) when necessary. And we can allow certain entities to become out of sync for longer periods without risking the integrity of any one game-wide "simulation". Generally speaking, entities that fall too far out of sync can either get dropped like a laggy player, or will be re-instantiated from a node of the network closer to the action, depending on it's level of importance to the current branch of the narrative/network or game conditions. Haha, well I hope that this rambling mess helps you understand what I'm doing better. The more I write it down the clearer it becomes to me. I started building this beast before I even knew what it was going to look like.

A little demo of what I have so far It's all coming up so nicely. I feel like a student again haha, trying many things until I just get it right (and leave no room for something fishy or not figured out). I'm not completely blocked for now. I'll add the downforce (starting with a simple force parallel to the normal to the ground surface below the car, multiplied by the velocity of the car in its local coordinate system), then friction (so that I can push the engine much further, as it's currently almost free-wheel, and it can fight gravity better, allowing for fun, arcade slopes) and change the shape of the car collider obviously (sphere?). Will keep you posted thinking about starting a project topic btw, if you have something for that? CarGame-v1.mp4 Yup exactly! Thinking about doing exactly that. Like him I have a target suspension compression of 0.75 (well in my system it means the opposite of him, where 1 is fully extended and 0 compressed), so I'm thinking about increasing the damping a lot when we reach 0.25, this way the car body will never actually hit the ground. This is one of the things that are so easy to do when you do it your own way: I believe Crash Team Racing didn't even check for collisions on the bottom of the body, only simple sideways checks, and then restituting the same equivalent force to both bodies so that they split quickly, and for walls it's likely the same as they do in most FPS (one thing that I haven't grasped at all yet).
6. ## Interpolation over Mesh

You're sweating the interpolation algorithm but skimp on how the vertices in question know the colours of their neighbours. Is colour a component of vertices or determined based on something like textural coordinates? Is this a pre-computed operation or something you want to do runtime, if so how? How do you associate vertices, by triangle neighbour relationships or by vector distance apart?
7. Today
8. ## Interpolation over Mesh

Given a mesh with N vertices suppose that we know the colors for a subset of those vertices. How to interpolate the colors at the known vertices to the other vertices? I've only seen one paper called "Interpolation on a Triangulated 3D Surface" that it looks like MATLAB implements in mesh_laplacian_interp. However, this paper looks kind of old and I'm wondering if better algorithms have been developed since then.

Can't say for xcom, but in vanilla Ja2 interrupts are completely determined (mostly by experience level), there were no random interrupts in original game.

I have got both planes to shoot bullets in all directions.
13. ## A cosplaying character - Will this be a copyright issue?

Hello! In my game, there's a character that loves cosplaying. Everytime you meet him ingame, he'll be wearing different clothes related to animes/cartoons/games/movies/people. He also dislikes pants and is always in his underwear and flip flops, which is one of the ways you can recognize him. His physical shape also changes everytime you meet him, as a part of a joke that is explained in game. This design choice will be a core part of the game's story and I wanted to know if there are any copyright issues. He'll never reveal which character he's cosplaying and it won't be super obvious. The player has to guess who he is (i don't know if that changes anything copyright related, but I thought I should mention it). Here's what 3 of his cosplays looks like (einsten, luffy and popeye): Does anyone know if I'll have copyright issues with this? Thank you!
14. ## Server-side and Client-side Animations in Unity

I believe you may be referring to Player Character Animations and Network Player Character Animations? Well, that's what I call them anyhow. The Animations themselves are no different in nature. It's the controller that is different, one(the Player Character) is controlled by the Game client's input devices, either directly or relayed to the server first for authorization, and the other is controlled by the server according to input from another player's Game Client. They are both generally speaking animated rigs with meshes that are made in 3D modeling software, usually different assets altogether, but still just 3d models with animations. Let me know if I misread or missed a point you would like some further help with. There are lots of options for adding network play to your games in Unity, are you using one of those or are you trying to build your own?

One simple way would be to have each asteroid have a size, and when you shoot an asteroid spawn a smaller asteroid (size 1 or 2) and decrease the size of the asteroid that was shot by the size of the spawned asteroid.
17. ## 1943 Plane Game

I am still working on my 1943 plane game. I have got the one plane to move and shoot bullets in all directions. I am going to do the same for the second plane.

The book Texturing and Modeling: A Procedural Approach was super helpful for me. That being said, on Amazon it's listed for 101 USD for the hardcover edition, which is way more than I paid for it many years ago. A lot of the information in that book can be found online, as it deals greatly with things like fractal noise. 19. ## Auth tokens The data in the token is potentially encrypted and signed, but that doesn't protect it against interception and re-use in transit, unless you also have transport security (such as HTTPS.) 20.

(for prototypes and whatnot) Are there any resources you've used that have been very helpful and stood out to you when learning art skills as programmers? 23. ## Find infinity or a rect from set of 'halfspaces' 2d Not really, but what you describe sounds like building / using a 2D BSP tree. There the definition of 'Halfspace' is one or the other side of a single line which seperates them. (The line can have start and end point, but it is extended to infinity when dividing space.) Then each of the two spaces can be divided further recursively to two child subspaces, using new lines which form intersections with the parent line. (Those intersections clip the child lines so they are no longer infinite.) The result is always a set of convex cells. Finding Boxes which fall into a certain subspace can be done efficiently by traversing the tree bottom down, and of course you can limit your seperating lines to be axis aligned. The first Doom game used this kind of trees to define its levels. 24. ## [Android][PC][Unity][Youtube] Turn Based Strategy RPG (Progress) tldr; -> just read the bold words Youtube Updates: https://www.youtube.com/watch?v=vPQltrr-Juo About This Project What is the name of the project, you might ask. The project is nameless right now since this game will be created all around the creative influence of it's early community. The problem of a community-driven creative process is the many developers or their games lose their identity and personal touch. My goal is to find a perfect balance between community influence and my personal taste. This is my first game which I aim to professionally release on several platforms. I am ready to embrace the challenge and also prepared for a (hopefully) not to bumpy ride and I invite you all to join me. About The Game I do not want to give too much away yet but the basic idea is to design a game which has a turn-based strategy system. You are a hero who controls an army of restless souls which are the classic RPG breeds - Ghouls, Ghosts, Skeletons, etc. There are several kingdoms in this realm who fight for territory. You used to be a hero, but your name has been forgotten. In this realm, every soul that enters it is nameless and unimportant. Though, it is still possible to make a name for yourself and your underworld kingdom. You are a commander of battle and a commander of war. You collect souls to fight for you in battle, strategically place your man and spread fear among those who try to stand in your way. The goal is to make this realm yours. There will be a few classes to choose from. If the interest in this game is big enough, I will consider adding more. Right now, I plan to add 3 to 4 classes. Planned features are: Boss fights Stamina System (Each turn +1 Stamina) Experience System Optional Hardcore Mode Highscore Items and Equipment Alchemy Interactable objects on the battlefield (e.g. temporary boosts, Small Story-line (main focus is on the gameplay) Not planned yet, only in future updates if: Crafting system More items PVP More customization More Storyline More Maps How can you help? There will be weekly votes on several aspects of the game on forums and maybe someday youtube. Just vote! Give advice and feedback Constructive Criticism Follow on Youtube and like the videos (only if you really like them!) Spread the word Donate assets (3D Models, 2D GUI, Textures, Unity Terrains, etc.) They will only be used if they fit into the games design Pricing As passionate gamer on a budget, I dislike the idea of overpriced titles and Micro-payment. Of course, it would be too early to determine a price and marketing strategy just yet. But I can promise that this title will cost under 20€ on PC. On Android it will probably cost around 5€ at most. Multiplayer Since it is my first project, I have not planned to implement multiplayer, just to keep things simple. But the main reason for that is that currently there would be too few players to play online, resulting in a poor multiplayer experience. Local multiplayer could be a considerable option. About Myself I am 22 years old and I study Computer Science in Germany. My main programming language is C#. If you want to know more, feel free to ask!

Some text that change when klicking on a button (screen flash becose the window get destroyed and recreated). None are persistand. buttons tend to overlap Using the wrong tools is just a pain and that is what i learned. Also i did had a text based game before going to opengl (perhaps a bit to soon) writers most of the time asume you continue writing code with previous example. i asume that in the example shows the code that makes the example work. i don't have other ppl to ask becose the ppl i know don't do code. i've learned that c++ for linux often opens with void() or main() for windows c++ often opens with int main () both are correct and can be used on different senario. int main () works for both and void works a bit more specific for windows therefore is int main() sometimes beter to be used. (i might be wrong but that is how i got some code working) 26. ## I will help you with programming. I use Unity Hello, I am Ukrainian guy who is interested in gamedev.

If you are an artist do not be shy and write me here. But pls, no super duper MMO or something like that) 27. ## understanding viewport opengl I get the sense you have an objection, but I'm not entirely clear what it is. I'm also not clear why you put 'framework' in scare quotes, or if your comments about SDL are directed at me (they don't seem to relate to anything I said specifically). In any case, I stand by my original suggestion. The OP seemed to be attempting low-level cross-platform development without having a good grasp on some important fundamentals. I and others suggested that might not be the best strategy. This seems fairly uncontroversial to me. If there's some particular statement or suggestion you disagree with, maybe you could quote just that part and say why you disagree. Anyway, not trying to be difficult I'm just a little confused by the conversation, that's all. 28. ## Advice for a young game writer...

You're saying (if I understand you correctly), "either write platform-specific code or use a framework". I am saying, "out of these two options, using a third-party library (not necessarily the same as a "framework") is the better choice." We both agree that these two are the only options, because it is flat-out impossible to write platform-independent OpenGL code without using a third-party library of some sort. Note that SDL doesn't abstract away OpenGL unless you use the 2D rendering API (which I would not recommend). It just creates the window and OpenGL context for you and feeds you input events. So using SDL isn't an alternative to using OpenGL with C++, but a tool for using OpenGL in C++ more effectively. 32. ## [Rev-Share] Looking for a PR/Marketing/Social Media Expert bump 33. ## Knockout Knockout is a free online boxing game available for Android and IOS Choose and customize your character Train your character and fight online to build your stats!

Look up "constant acceleration" on the web. The formula you wrote describes the velocity under constant acceleration. The "1/2" and the "^2" come from integrating that formula to get the position under constant acceleration (the integral of x from 0 to t is t^2/2). Acceleration --(integrate)--> Velocity --(integrate)--> Position Acceleration <--(differentiate)-- Velocity <--(differentiate)-- Position If you know nothing about calculus, ignore everything in this post except the first line.

Two ways to think about it: (1) Imagine the points of space that can be reached in time t, first with no gravity. It's simply a circle of radius v*t. Imagine that circle being animated over time. If you now introduce gravity, you can think of it as acting on the center of the circle, bringing it down as it grows. The formula (1/2)gt^2 is just the position under constant acceleration. (2) If you use a frame of reference in free fall, there is no gravity. Using that frame of reference corresponds to the change of variable y' = y + (1/2)gt^2, and in these (x,y') coordinates you are back to the situation without gravity. 47. ## How to understand the equation on "Angle required to hit coordinate (x, y)"? Hey Alvaro, can you help me to understand the "(1/2)gt^2)^2" part in the second formula?
