  • Uniform not being applied to proper mesh

    - by HaMMeReD
    Ok, I got some code, and you select blocks on a grid. The selection works. I can modify the blocks to be raised when selected and the correct one shows. I set a color which I use in the shader. However, I am trying to change the color before rendering the geometry, and the last rendered geometry (in the sequence) is rendered light. However, to debug logic I decided to move the block up and make it white, in which case one block moves up and another block becomes white. I checked all my logic and it knows the correct one is selected and it is showing in, in the correct place and rendering it correctly. When there is only 1 it works properly. Video Of the bug in action, note how the highlighted and elevated blocks are not the same block, however the code for color and My Renderer is here (For the items being drawn) public void render(Renderer renderer) { mGrid.render(renderer, mGameState); for (Entity e:mGameEntities) { UnitTypes ut = UnitTypes.valueOf((String)e.getObject(D.UNIT_TYPE.ordinal())); if (ut == UnitTypes.Soldier) { renderer.testShader.begin(); renderer.testShader.setUniformMatrix("u_mvpMatrix",mEntityMatrix); renderer.texture_soldier.bind(0); Vector2 pos = (Vector2) e.getObject(D.COORDS.ordinal()); mEntityMatrix.set(renderer.mCamera.combined); if (mSelectedEntities.contains(e)) { mEntityMatrix.translate(pos.x, 1f, pos.y); renderer.testShader.setUniformf("v_color", 0.5f,0.5f,0.5f,1f); } else { mEntityMatrix.translate(pos.x, 0f, pos.y); renderer.testShader.setUniformf("v_color", 1f,1f,1f,1f); } mEntityMatrix.scale(0.2f, 0.2f, 0.2f); renderer.model_soldier.render(renderer.testShader,GL20.GL_TRIANGLES); renderer.testShader.end(); } else if (ut == UnitTypes.Enemy_Infiltrator) { renderer.testShader.begin(); renderer.testShader.setUniformMatrix("u_mvpMatrix",mEntityMatrix); renderer.testShader.setUniformf("v_color", 1.0f,1,1,1.0f); renderer.texture_enemy_infiltrator.bind(0); Vector2 pos = (Vector2) e.getObject(D.COORDS.ordinal()); mEntityMatrix.set(renderer.mCamera.combined); mEntityMatrix.translate(pos.x, 0f, pos.y); mEntityMatrix.scale(0.2f, 0.2f, 0.2f); renderer.model_enemy_infiltrator.render(renderer.testShader,GL20.GL_TRIANGLES); renderer.testShader.end(); } } }

  • Collision Detection for 2D

    - by Bhaskar
    I am working on a simple game, where I need to do a collision detection of two Texture2D. The code I have written is: bool perPixelCollission = false; Texture2D texture1 = sprite1.Texture; Texture2D texture2 = sprite1.Texture; Vector2 position1 = new Vector2(sprite1.CurrentScope.X, sprite1.CurrentScope.Y); Vector2 position2 = new Vector2(sprite2.CurrentScope.X, sprite2.CurrentScope.Y); uint[] bitsA = new uint[texture1.Width * texture1.Height]; uint[] bitsB = new uint[texture2.Width * texture2.Height]; Rectangle texture1Rectangle = new Rectangle(Convert.ToInt32(position1.X), Convert.ToInt32(position1.Y), texture1.Width, texture1.Height); Rectangle texture2Rectangle = new Rectangle(Convert.ToInt32(position2.X), Convert.ToInt32(position2.Y), texture2.Width, texture2.Height); texture1.GetData<uint>(bitsA); texture2.GetData<uint>(bitsB); int x1 = Math.Max(texture1Rectangle.X, texture2Rectangle.X); int x2 = Math.Min(texture1Rectangle.X + texture1Rectangle.Width, texture2Rectangle.X + texture2Rectangle.Width); int y1 = Math.Max(texture1Rectangle.Y, texture2Rectangle.Y); int y2 = Math.Min(texture1Rectangle.Y + texture1Rectangle.Height, texture2Rectangle.Y + texture2Rectangle.Height); for (int y = y1; y < y2; ++y) { for (int x = x1; x < x2; ++x) { if (((bitsA[(x - texture1Rectangle.X) + (y - texture1Rectangle.Y) * texture1Rectangle.Width] & 0xFF000000) >> 24) > 20 && ((bitsB[(x - texture2Rectangle.X) + (y - texture2Rectangle.Y) * texture2Rectangle.Width] & 0xFF000000) >> 24) > 20) { perPixelCollission = true; break; } } // Reduce amount of looping by breaking out of this. if (perPixelCollission) { break; } } return perPixelCollission; But this code is really making the game slow. Where can I get some very good collision detection tutorial and code? What is wrong in this code?

  • Path Modifier in Tower Of Defense Game

    - by Siddharth
    I implemented PathModifier for path of each enemy in my tower of defense game. So I applied fixed time to path modifier in that enemy complete their path. Like following code describe. new PathModifier(speed, path); Here speed define the time to complete the path. But in tower of defense game my problem is, there is a tower which slow down the movement of the enemy. In that particular situation I was stuck. please someone provide me some guidance what to do in this situation. EDIT : Path path = new Path(wayPointList.size()); for (int j = 0; j < wayPointList.size(); j++) { Point point = grid.getCellPoint(wayPointList.get(j).getRow(), wayPointList.get(j).getCol()); path.to(point.x, point.y); }

  • DirectX 9.0c and C++ GUI

    - by SullY
    Well, I'm trying to code a gui for my engine, but I've got some problems. I know how to make a UI overlay but buttons are still black magic for me. Anything I tried was to compilcated ( if it goes big ). To Example I tried to look if the mouse position is the same as the Pixel that is showing the button. But If I use some bigger areas it's getting to complicated. Now I'm searching for a Tutorial how to implement your own gui. I'm really confused about it. Well I hope you have/ know some good tutorials. By the way, I took a look at the DXUTSample, but it's to big to get overview.

  • Costs/profit of/when starting an indie company

    - by Jack
    In short, I want to start a game company. I do not have much coding experience (just basic understanding and ability to write basic programs), any graphics design experience, any audio mixing experience, or whatever else technical. However, I do have a lot of ideas, great analytical skills and a very logical approach to life. I do not have any friends who are even remotely technical (or creative in regards to games for that matter). So now that we've cleared that up, my question is this: how much, minimally, would it cost me to start such a company? I know that a game could be developed in under half a year, which means it would have to operate for half a year prior, and that's assuming that the people working on the first project do their jobs good, don't leave game breaking bugs, a bunch of minor bugs, etc.. So how much would it cost me, and what would be the likely profit in half a year? I'm looking at minimal costs here, as to do it, I would have to sell my current apartment and buy a new, smaller one, pay taxes, and likely move to US/CA/UK to be closer to technologically advanced people (and be able to speak the language of course). EDIT: I'm looking at a small project for starters, not a huge AAA title.

  • I'm looking to learn how to apply traditional animation techniques to my graphics engine - are there any tutorials or online-resources that can help?

    - by blueberryfields
    There are many traditional animation techniques - such as blurring of motion, motion along an elliptical curve rather than a straight line, counter-motion before beginning of movement - which help with creating the appearance of a realistic 3D animated character. I'm looking to incorporate tools and short cuts for some of these into my graphics engine, to make it easier for my end users to use these techniques in their animations. Is there a good resource listing the techniques and the principles behind them, especially how they might apply to a graphics engine or 3D animation?

  • Story and news-feed ideas for social network games

    - by arpine
    I am currently working on a educational and fun 2-in-1 game. As I am not a professional, I need advice on story and news-feed. The goal is simple-get richer, the story is about a worker who is trying to get over his/her financial problems and become rich. During the whole gaming process there is a news-feed (every day there are a couple of fresh news about what is going on). The news are fresh and individual so I need to write about 2000 pieces of news for 2 year gaming, maybe more. The problem is that I am not sure whether repetitive news can interest in this game. What can be done to make the news-making process easier but not boring from the point of view of the player?

  • How to check battery usage of an iPhone/Android app?

    - by Gajoo
    I think the title says Enough. For example Unity can generate you a report how much CPU/GPU power it's using or how fast it's going to drain device battery, but what about the applications developed using Cocos2d or the ones you develop directly using OpenGL? How should you profile them? In general what should you profile? or Should I simply run the application and wait for it's battery to run out?

  • Cocos2D: Upgrading from OpenGL 1.1 to 2.0

    - by Alex
    I have recently starting upgrading my ios game to the latest Cocos2D (2.0 rc), and I am having some difficulties upgrading my texture generation code to OpenGL 2.0. In the old version I generated images with this code: CCRenderTexture *rt = [CCRenderTexture renderTextureWithWidth:WIDTH height:HEIGHT]; [rt beginWithClear:bgColor.r g:bgColor.g b:bgColor.b a:bgColor.a]; glDisable(GL_TEXTURE_2D); glDisableClientState(GL_TEXTURE_COORD_ARRAY); glVertexPointer(2, GL_FLOAT, 0, verts); glColorPointer(4, GL_FLOAT, 0, colors); glDrawArrays(GL_TRIANGLE_STRIP, 0, (GLsizei)nVerts); glEnableClientState(GL_TEXTURE_COORD_ARRAY); glEnable(GL_TEXTURE_2D); [rt end]; But since OpenGL 2.0 works differently this code won't work. What is the best way to use the new OpenGL?

  • Textual descriptions of 8-bit and 16-bit game engines

    - by ixtmixilix
    I found a good description of the engine in the Sonic games. It describes roughly how the engine works for people writing their own clones. In my case, I am simply interested in getting a general view of how the many 8-bit and 16-bit game engines worked on their respective consoles. So, this is a big-list style question asking, what other online descriptions of specific game engines have people found?

  • Free vs. Paid: Picking a Financial Model

    - by ashes999
    I finally embarked upon my first "paid" game. What this means is that I will incorporate some sort of monetization strategy in my game. This may mean making the app pay-to-download, making it "freemium" with paid content, or something else. Having never done something like this, I'm at a complete loss as to how to figure out what I should do. I know a couple of models (pay to download, freemium, etc.) and I can brainstorm some ideas. But how do I figure out what strategy to use? Perhaps there's some body of research on this? (I recall reading that MMOs popular in Korea use a model where cosmetic changes only are pay-to-buy; everything else is free).

  • How can I spawn a sprite based on a condition after the game starts?

    - by teddyweedy
    How do I spawn a sprite anytime later in the game when the game starts? I'm using FlashDevelop with Flixel. I did try it in override public function create(): void. It works only in the beginning. I try it using if (FlxG.score == 1) but it doesn't work. I also tried it in override public function update(): void. It works and it is moving but it leaves a sprite making it a multi-sprite. I also did try FlxGroup but to no avail.

  • Spherical to Cartesian Coordinates

    - by user1258455
    Well I'm reading the Frank's Luna DirectX10 book and, while I'm trying to understand the first demo, I found something that's not very clear at least for me. In the updateScene method, when I press A, S, W or D, the angles mTheta and mPhi change, but after that, there are three lines of code that I don't understand exactly what they do: // Convert Spherical to Cartesian coordinates: mPhi measured from +y // and mTheta measured counterclockwise from -z. float x = 5.0f*sinf(mPhi)*sinf(mTheta); float z = -5.0f*sinf(mPhi)*cosf(mTheta); float y = 5.0f*cosf(mPhi); I mean, this explains that they do, it says that it converts the spherical coordinates to cartesian coordinates, but, mathematically, why? why the x value is calculated by the product of the sins of both angles? And the z by the product of the sine and cosine? and why the y just uses the cosine? After that, those values (x, y and z) are used to build the view matrix. The book doesn't explain (mathematically) why those values are calculated like that (and I didn't find anything to help me to understand it at the first Part of the book: "Mathematical prerequisites"), so it would be good if someone could explain me what exactly happen in those code lines or just give me a link that helps me to understand the math part. Thanks in advance!

  • Player & Level class structure in 2D python console game?

    - by Markus Meskanen
    I'm trying to create a 2D console game, where I have a player who can freely move around in a level (~map, but map is a reserved keyword) and interfere with other objects. Levels construct out of multiple Blocks, such as player(s), rocks, etc. Here's the Block class: class Block(object): def __init__(self, x=0, y=0, char=' ', solid=False): self.x = x self.y = y self.char = char self.solid = solid As you see, each block has a position (x, y) and a character to represent the block when it's printed. Each block also has a solid attribute, defining whether it can overlap with other solids or not. (Two solid blocks cannot overlap) I've now created few subclasses from Block (Rock might be useless for now) class Rock(Block): def __init__(self, x=0, y=0): super(Rock, self).__init__(x, y, 'x', True) class Player(Block): def __init__(self, x=0, y=0): super(Player, self).__init__(x, y, 'i', True) def move_left(self, x=1): ... # How do I make sure Player wont overlap with rocks? self.x -= x And here's the Level class: class Level(object): def __init__(self, name='', blocks=None): self.name = name self.blocks = blocks or [] Only way I can think of is to store a Player instance into Level's attributes (self.player=Player(), or so) and then give Level a method: def player_move_left(self): for block in self.blocks: if block.x == self.player.x - 1 and block.solid: return False But this doesn't really make any sense, why have a Player class if it can't even be moved without Level? Imo. player should be moved by a method inside Player. Am I wrong at something here, if not, how could I implement such behavior?

  • How to detect a touch on transparent area of an image in a (libgdx) stage?

    - by Usman
    Can some one please help to detect a touch on an image which I am using as an actor in a stage. The image is actually a long diagnol brush which has plenty of transparent area. The problem is when I touche the transparent area of the brush image it is also triggering the clicklistener of the image. I need the click listener should only be called when the finger actually touched the visible image not the area which is empty. I am using libgdx-0.9.4 libraries. Here is my simple piece of code. import com.badlogic.gdx.scenes.scene2d.ui.Image; import com.badlogic.gdx.scenes.scene2d.ui.ClickListener; Image brushImg = new Image(ImageCache.getTexture("brush")); brushImg.width = mStage.width()*0.75f; brushImg.height = mStage.height()*0.75f; brushImg.setClickListener(new ClickListener() { @Override public void click(Actor actor, float x, float y) { SoundFactory.play("brush"); }

  • How to give parallax backgrounds more depth

    - by user28015
    I have 3 tiled images of some sort of galaxy/space in the background of a 2D Game: The first one has an alpha of 100%, the second an alpha of 80% and the last one has an alpha of 60%. I scroll the the one in the background slower than the other ones of course. classic parallax. In the foreground I have some particles flying towards the player to simulate some dust / stars flying by. (I know that stars don't fly by, but I think we all have seen this in a lot of games). But I can't quite achieve the depth effect I am looking for. I want it to look "deeper". I did read something about using blending modes for the backgrounds, but that would require to render them as objects right? So the question is: What is a good technique to do a scrolling parallax background in GameMaker?

  • How can I efficiently update only the entities that matter in a given frame?

    - by lezebulon
    I'm making a RTS, which can potentially have lots of units in one map (think Age of Empires). I'm looking for a way to update my units. I want to avoid calling a virtual Update() method every frame on every entity. On the other hand, units that are not in view should still be updated and behave "normally." I'm assuming this is a fairly standard question; what would be a way to handle this situation?

  • 2D Ragdoll - should it collide with itself?

    - by Axarydax
    Hi, I'm working on a ragdoll fighting game as a hobby project, but I have one dilemma. I am not sure if my ragdoll should collide with itself or not, i.e. if ragdoll's body parts should collide. 2D world is somewhat different than 3D, because there are several layers of stuff implied (for example in Super Mario you jump through a platform above you while going up). The setup I'm currently most satisfied with is when only the parts which are joined by a joint don't collide, so head doesn't collide with neck, neck with chest, chest with upper arm etc, but the head can collide with chest, arms, legs. I've tried every different way, but I'm not content with either. Which way would recommend me to go?

  • Corona sdk events dispatched with dispatchEvent() are handled directly upon call. Why so?

    - by Amoxus
    I noticed to my surprise that an event created with dispatchEvent(event) gets handled directly when called, and not together with other events at a specific phase of the frame loop. Two main reasons of having an event system are: so that you can call code B from code A, but still want to prioritize code A. to make sure there are no freaky loopedy loops where code A calls code B calls code A ... I wonder what Ansca's rationale behind having events being handled directly this way is. And does Corona handle loopedy loops and other such pitfalls gracefully? The following code demonstrates dispatchEvent(): T= {} Z = display.newRect(100,100,100,100) function T.doSomething() print("T.doSomething: begun") local event = { name="myEventType", target=T } Z:dispatchEvent( event ) print("T.doSomething: ended") end function Z.sayHello(event) print("Z.sayHello: begun and ended") end Z:addEventListener("myEventType", Z.sayHello) print("Main: begun") T.doSomething() print("Main: ended") However Ansca claims the contrary at http://developer.coronalabs.com/reference/index/objectdispatchevent Can anyone clear this up a little? ( Using Corona simulator V 2012.840 )

  • Geometry Shader : points + Triangles

    - by CmasterG
    I have different Shaders and for each Shader a instance of the ShaderClass class, which initializes the Shaders, Renders the Shaders, etc. I use most of the Shaderclasses without Geometry Shader, but in one Shader Class i also use a Geometry Shader. The problem is, that when I render one object with the Shaderclass that uses the Geometry shader, all other object are rendered with the same geometry that I create in the Geometry Shader. Can you help me? Is it possible that I have to use a Geometry Shader for each object, when I use one for one object? I use DirectX 11 with C++.

  • Storing a Hex Grid

    - by Pedro Caetano
    I've been creating a small hex grid framework for Unity3D and have come to the following dilema. This is my coordinate system (taken from here) Link because I'm a new user It all works pretty nicely except for the fact I have no idea how to store it. I originally intended to store this in a 2D array and use images to generate my maps. One problem was that it had negative values (this was easily fixed by offsetting the coordinates a bit). However, due to this coordinate system, such an image or bitmap would have to be diamond shaped - and since these structures are square shaped, this would cause a lot of headaches even if I hack something together. Is there anything I'm missing that could fix this? I recall seeing a forum post regarding this in the unity forums but I can no longer find the link. Is writing a set of coordinate translators the best solution here? If you guys think it would be helpful, I can post code and images of my problem.

    I am playing around with 3d transformations and came along an issue. I have a 3d vector already within the viewport and need to transform it to a 2d vector. (let's say my screen is 10x10) Does that just straight works like regualar transformation or is something different here? i.e.: I have the vector a = (2, 1, 0) within the viewport and want the 2d vector. Does that works like this and if yes how do I handle the "0" within the 3rd component?
