4. ## Need some ideas

You could still have obstacles couldn't you (downed pillars, rocks, holes, etc.)? You did say you would see enemies wondering around the map as well correct?
5. ## Humanitarian Gamification: Designing a game to save the world?

A name for the game has actually come up along those lines, but I'm supposed to keep it a secret. And I HAAAATE keeping secrets!!!
6. ## Quick lane-changing movement of player object

So this is like a racing game on rails? I like irreversible's approach, slight possible tweaking: You could label each lane numbered, -1, 0, 1, 2 etc. Store the current lane position of the player as a float. Have a target lane number (as an integer) you are moving towards (could be the same as you are already in). Each iteration lerp the current lane towards the target lane (by a fixed amount if using fixed tick rate, or dT if using frame timing) On corners, preserve the lane information but because you are joining different 'segments' of track, do an additional lerp from one segment to another as you cross the corners. This way lane changing on corners 'just works'. If the difference between 2 players is less than some value (e.g. 0.5) they crash This might mean you can only turn e.g. left into a single side road from the left lane, which you may or may not want. You would also have to handle crashing on corners involving turning vehicles.
7. ## Project BlockchainZ [Available on itch.io]

[BzPatch 2]: Updates and improvements! Hey everybody! New Patch is here! Say hello to Patch 1.0.2b (Patch notes below) A new update with nice improvements for a better game experience. Firstly we have reworked so hard the AI, so now they will react much better to the different situations, more work will be added, like advanced behaviors, different animations and there will be more in futures patches! Also we've done optimizations in the shooting feedback, first we add some shake to the camera. Also we have been working a lot in the IK stuff so when you shoot the gun move the character's arms and shoulders. And we have changed nearly all the SFXs for a more interesting version. Give it a try, you will notice with the first shoot. What is IK? IK is the acronym for Inverse Kinematics. IK is an animation technique that allows much more responsive animations in games. Unfortunatelly, this improvement forces us to turn off the option to disable the Right/Left Angle shooting until the next patch 😢 You'll see that now the difficulty level is a little bit more harder (We also took out rookie level), because we want the video game to be a really interesting challenge for every zombie killer. Nobody said that killing zombies was easy. The real challenge is to survive until your reinforcements arrive. Finally, and not less important, we have corrected some nasty bugs! Are you capable to save the bunker? Prove it and save the world: https://projectblockchainz.itch.io/projectbcz PSD.: we are still working on the story. And now we are so happy to show you some of the concept arts we have prepared. Check it! When we started developing the video game, we had the idea to create a huge city completely ruined by thousands of years of struggling. It would be a desolated scenario... More on the Devlog What do you think? Let us know on our Discord Server. Patch Notes: General improve on AI, now the bandits reacts much better. Big optimization in shooting feedback. Camera improvements. SFX improvements. IK optimizations. New SFX for each every weapon. Now the foots adjust to the terrain. The character reacts when is hitted. Fixed zombie speed bug. Not the zombies let some space after attacks. Rookie challenge level removed. Now the challenge level includes the difficulty. Challenge level adjustment in order to create a more interesting challenge for the player. Fixed some related bugs on AI. Aiming by the left is temporarily disabled while improving the character's IK. Now you can't train the last civilian in the bunker. Fixed the bug related to the updates, now it works fine. Some adjustment to max units at the same time, to avoid performance hitccups Minor Bugs Additionally, we are working on the auto-resolve feature that let the easy battles be done without wasting time Eg. when you have 20 soldiers and fight against 3 raiders. These kind of battles have no sense at this point, so we believe player doesn't need to waste time them. Just focus in the good ones. Once we have this feature totally balanced and tested, we'll update it in the next update! We really hope you enjoy these new improvements. If you find any bug, please tell us right here or through our Discord Server. Thanks a lot for all the support you are bringing to us. It's great to know how do you feel about Project BlockChainZ.

10. ## Quick lane-changing movement of player object

Technically, if you change lane, you're moving (somewhat) diagonally, so your forward movement speed decreases. Likely you don't want to model that
11. ## Orchestral Composer looking for Game Projects

Hi everyone, I'm an orchestral music composer with 5 years experience. Now I would like to get experience in making music for games. I'm specialized in epic music and traditional big orchestrations, you can listen to some of my work on soundcloud/youtube at the bottom. Please contact me if you are interested, would love to hear from you. Best regards, Jonathan Soundtrack Portfolio: Rescored Trailers I did for practice:
12. ## Diligent Engine - A Modern Cross-Platform Low-Level Graphics Library

I started work on DiligentFX, a high-level renderer. As the first step, I reworked epipolar light scattering effect and made it ready-to-use component with a clear interface. Check it out on GitHub.
13. ## Islands and Land

Yes, that is the ideal situation but it's not currently supported. There are some issue requests open for it, so hopefully it gets implemented eventually. My latest CPU numbers were just under 50% all-in, including the rest of the physics, rendering, etc. I'm not sure what I'm at for just my code. In that scene, 2 of the 3 boats were unoptimized, there are probably around 2000 potentially-buoyant faces in total, so a simpler hull should make a significant difference. I'm releasing what I have this week, and one of my goals for a future version will be to offer some options to trade accuracy for speed. I'll be sure to give it a go on mobile to see how things hold up. As you noted, this would prevent the inside of the boat from rendering. You need to sandwich the depth rendering of the closed hull between the rendering of the boat and the water. If you do find a better workaround, I'd love to know!
14. ## Islands and Land

Ahha! I have a solution, possibly. Draw the hulls first using colour without blending. This draws the colour and depth, no blending and is cheap. Draw a skybox over this, without using depth testing or depth write. This will draw the colour over the previous result. Now draw the boats. Now draw the ocean. I think this might work and would be super cheap. 🙂 /edit Ah darn this may interfere with the boat rendering. However you could use it to draw masked areas maybe, or get it to work with a cunning shader. I'm sure there must be a cheap solution! 🙂
15. ## A lack of Raypunk / Pulp Sci Fi games?

(note: there is ambiguity about where the line is drawn between raypunk - or raygun gothic - and atompunk as used in games like Fallout. I have attached a couple of images to illustrate the style I am talking about) Lately I have started browsing artwork and pictures of old science fiction movies from the 50's/60's again and started wondering - why isn't that aesthetic explored in videogames more frequently? It's a fresh and most of the times vibrant look at a future that never was, far away from the sleek designs of Mass Effect and the bleak colour palette of your average first person shooter. Let's face it, how many games can you name where the skies are a nice and warm yellow colour? Illustrators and film makers alike didn't care about realism and explored the realms of their imagination while throwing the laws of physics out of the window of their saucer shaped spaceships, and they gave us movies like This Island Earth or Forbidden Planet and the classic Star Trek series in return. So I have been trying to come up with a genre or game mechanic and I think a more campy and over-the-top version of something like Age Of Wonders would work great (yes, Planetfall might be set in a sci-fi setting but it's going in the complete opposite direction). Who wouldn't want to engage in diplomatic conversation with this friendly fellow while your fellow band of spacemen and -women fight off strange creatures with their trusty rayguns? What do you all think - is this a theme/idea worth exploring? What would make you want to play the 4X version of a 50's science fiction movie? Or would this lend itself better for a different genre instead?
16. ## Islands and Land

It might work but usually stuff like that is a big red flag to take care in case of pipeline stalls etc I think. It is all a roundabout way of trying to write to the depth buffer without writing out colour as I understand it? There may be a way of using alpha blending with transparent pixels, and getting the sorting / render order correct, maybe this will be faster. I think there is some support for changing the render order in Godot (I did it for my skybox) but I don't know if you can force this even with blending where things are often sorted back to front. Speaking for myself I'm also keen to have stuff that will work fast on mobile, so you have to be careful as things like that can kill the framerate for little visual gain. Also this is why my emphasis on shortcuts in the calculations, I saw from your latest version it was using 30-50% CPU. To give comparison, I think mine uses very low, figures around 0.1% CPU for 30 or so boats. However I think your approach could be optimized by using simplified hull (maybe a box or something) and lookup tables if you are feeling brave. I may get round to having a go at this when I eventually get home and can program again! :-)

18. ## Humanitarian Gamification: Designing a game to save the world?

OK. That's a good focus. To get some ideas flowing, think of sayings or phrases other than the paper cuts thing. Like daily good deeds, or "paying it forward," or mountains from molehills.
19. ## Islands and Land

Good point. I looked into it a little more and found it in the official documentation: http://docs.godotengine.org/en/3.0/tutorials/shading/screen-reading_shaders.html I think it should perform the same as any other screen-space post-processing shader (although I wonder if that means it would interfere with those as well), and it will only capture the screen texture once so having several boats using this at the same time won't decrease performance.
20. ## C#GUI WPF + OpenGL 3.1

It would likely be a win in court regardless. Trademarks don't prevent all use, just certain specific uses. Trouble is, nobody wants to be the one to set precedence in court, including Turbosquid, who settled out of court recently with BMW for selling car models with the logo. (I think it was BMW) Anyway, it's a touchy subject because people think trademarks are all powerful because of the status quo and can't reason about it objectively with legal jargon. It's like telling someone that cholesterol isn't bad for you after all the years of being told that cholesterol = bad!

If in doubt, use a large site like turbosquid, and pay something for the models. They have some very expensive models on there, but also some very good ones for pocket change. Most of my 3D models in my game come from there and/or are kitbashes of stuff on there. Because you've paid them, and they've certified and guaranteed that the license is correct, so long as you abide by the reasonable terms (e.g. don't go using a porsche in your racing game or an AK-47 in your first person shooter!) if someone did try to sue you, you have reasonable defence that you bought it from turbosquid, and paid for it, and turbosquid have done their due diligence, which pins the fault clearly on the asset's seller. It's not completely watertight and I am no lawyer, but this is how i see it, and it's common sense to me. I'm sure if someone was vindictive enough, they could go after you, turbosquid, and the seller of the asset together. If in doubt, take legal advice, if still in doubt don't do it!

36. ## Quick lane-changing movement of player object

Thanks for the insight! This seems like a solid plan as I would have to define the lanes eventually anyway. In this case the object should only lerp over either the x- or z-axis, depending on which direction the lane goes (or maybe this is not necessary if I keep the transformations local?). When the player is on an intersection (inside the red box in the picture), instead of changing lanes the player turns left or right on the road. Currently not in a position to try this approach but assuming the player has a constant forward movement, adding a lerp over a single axis won't interfere?

It amazes me how much is stolen on sites that sell 3D models... Thankfully I don't buy assets from such hubs, only through channels I know and trust if I don't do it in house or myself personally.

And be aware that a lot of assets marked as 'personal use' are stolen assets, that the uploader has no rights to distribute. (The implication being that if you are just using them personally and not distributing, the original owners won't find out)

40. ## c# console snake game

I just converted my console snake code to GDI. Just to show how a good design can be easily used with any underlying drawing method. So really, discussion about which is 'harder' is moot. Phil, happy to take you through the design process step by step if you like.

So essentially the changes I made are: Create a WinForms app instead of Console (obviously) Move my game loop code from a for loop to a timer Tick Move UpdatePlayfield() into the form Paint() Change WriteAt (which wrote on the console) to DrawCell (to draw on the form) That's pretty much it! Apart from some minor stuff which I'll go into next post. Some of the code can still be removed, e.g. there's no need to 'erase' the last snake tail piece as in the console version, and we could use different keyboard technique, but it works BTW I'm not saying this is a great design, it's quick and dirty to be honest, which was the original intention (to get it done fast, but not throwing good design right out the window..)
42. ## c# console snake game

I think @phil67rpg wants to create a list of foods in random position. Or maybe I understand wrong. Okay, lets generate one food after eating. You can replace it with one line of code with built in class Point: Point foodPos = new Point(0, 0); @phil67rpg what do you want to add in your code next? using System; using System.Collections.Generic; using System.Drawing; using System.Windows.Forms; namespace SnakeByPhil_WinFormsGDI { public partial class Form1 : Form { public Form1() { InitializeComponent(); CenterToScreen(); timer1.Interval = 200; timer2.Interval = 500; timer2.Start(); } int x = 0, y = 0; Random rnd = new Random(); int move = 1; Point foodPos = new Point(0, 0); private void timer2_Tick(object sender, EventArgs e) { move = rnd.Next(1, 5); foodPos.X = rnd.Next(0, 290); foodPos.Y = rnd.Next(0, 290); } private void Form1_Paint(object sender, PaintEventArgs e) { Graphics g = this.CreateGraphics(); DrawRectangle(g, 340 + x, 280 + y, Color.Green); DrawRectangle(g, 330 + x, 280 + y, Color.Black); //DrawRectangle(g, 150 + x, 150 + y, Color.Green); //DrawRectangle(g, 140 + x, 150 + y, Color.Black); DrawRectangle(g, foodPos.X, foodPos.Y, Color.Red); g.Dispose(); } private void DrawRectangle(Graphics g, int x, int y, Color color) { SolidBrush brush = new SolidBrush(color); Rectangle rect = new Rectangle(x, y, 10, 10); g.FillRectangle(brush, rect); brush.Dispo﻿se(); } private void timer1_Tick(object sender, EventArgs e) { switch (move) { case 1: for (int i = 0; i <= 20; i++) { x++; } break; case 2: for (int i = 0; i <= 20; i++) { x--; } break; case 3: for (int i = 0; i <= 20; i++) { y++; } break; case 4: for (int i = 0; i <= 20; i++) { y--; } break; } if (MouseButtons == MouseButtons.Left) { } Invalidate(); } } }

46. ## Humanitarian Gamification: Designing a game to save the world?

In a perfect world, yeah, all of the above. But that's not realistic. The best answer is perhaps "the immediate community of a player". You help those around you, and it grows from there, with some of those you help teaming up with you to help others. E.g. you help a handful of kids with some learning through a learning (and testing) app, you help a homeless person you run into daily find a good place at a homeless shelter or even help him get back on his feet if possible. Small scale things, local. Or you may help someone somewhere help others, perhaps using some experience you have (like advising someone on how to help that homeless person find a good shelter and maybe get back on his feet). It's not a sword, but a thousand papercuts, if that phrase makes any sense here?

48. ## Humanitarian Gamification: Designing a game to save the world?

Totally. The Social Media platform will likely be a watered down Facebook thing, to make it recognizable and easy to navigate. The privacy and safety points are in the back of my head, but until I have a working suggestion for the game itself, they make no sense trying to design, of course....
49. ## Checking a Height Value Repeatedly

As with Zakwayda, I have tried very hard to understand what you were asking, but it has taken you a long time to even begin to pin down what you are trying to do, either through language difficulties or perhaps you didn't know what you wanted at the outset. It seems at this point you are trying to move a ball over a terrain. Is the ball rolling? Would a sphere be a better word? I'm getting the impression it cannot bounce. Is it moving only in the direction you provide, or can it roll sideways? We don't know, as you have been unable to ask the question precisely. What does the ball represent? Is it a ball, is it a player? We don't know. If you want to get more answers I strongly would suggest you start a new thread, and attempt to ask the question in a concise and precise fashion, perhaps get someone to help you who is more adept at the English language. There are plenty of folks here that are quite expert at physics (e.g. Dirk Gregorius, Randy Gaul etc), and I suspect part of the reason you haven't received more answers is that they would have to first spend ages try to decipher what you are trying to ask. Overall from what *I am guessing* you are looking for: The earlier suggestions I gave were all approximations. If you want to have a more accurate simulation I strongly suspect the answer you are looking for is: Use a physics engine Either a third party physics engine (preferably), or write one (or at least a subset). You expressed a wish for a 'simple' answer. Unfortunately some problems in games don't have a simple answer. This may not be a minor undertaking, as Zakwayda says many of the techniques are vulnerable to numerical error, and there are often special cases to debug and deal with. I would strongly advise if you really want to do this without a third party physics engine that you familiarize yourself with how they work (multiple bounces or slides per iteration), write your own at least for simple cases, and then you can apply the principles to come up with an approximate solution for this problem. You may be able to take advantage of some specifics of your case to make a more robust solution than a general case. For instance with a sphere, often you can treat the sphere path as a ray and 'push' the planes of collidees outwards to take account for the radius.
50. ## Humanitarian Gamification: Designing a game to save the world?

That thing that strikes me is that it would likely have to be a very social design - something that connects people with those around them. Unfortunately, that means you also need to deal with the potential problems that could come along with that -- privacy, public safety, etc. Perhaps you could somehow leverage or build off one or more existing social media platforms?
