  • How does a single programmer make a game?

    - by Mike
    I have always been a software developer, but lately I've been wanting to get into games. The only thing stopping me is the fact that I'm a programmer, not an artist. I've made some simple stuff, Tetris, 2D chess things like that but I can't do much art and that's really what holds me back. Now the problem is, I've yet to go to college so most commercial projects wouldn't accept me even to work for free and learn a bit especially with my lack of experience in games and any indie projects I've looked into really have an issue with responding to people interested, or actually completing (or starting really, most don't get past the ideas on paper) the project they want to do. I've looked around locally for artists, anyone who can do modeling, textures or animating or even anyone with some ability to make some more advanced 2D assets to get something like a side-scrolling RPG or something but haven't been able to find anyone. So how do you guys do it? Do I really just have to wait until I can go to college to see if I like working with games or is there some way I can get art (for free, anything I do is just going to be for fun so I don't want to have to sink money into it) and just start messing around on my own? Or am I just having bad luck and not looking in the right places for other people interested in having me help? I'm not looking for anything in particular, just something to fill some time with and see if I like making games. If not, well I'll go back to my software projects. I just have one more year of highschool and I'd like to try a few different areas before I go to college.

  • I have an "amoeba" game mechanic. Any idea on how to implement it?

    - by Jason
    Outside of a tetris clone, a crappy 2D top-down shooter, and some messing around with stuff like Unity and Flixel, I realize that I have yet to complete a single, polished, bells-and-whistles game. I want to change this, and I have an idea for my next project. The idea is that you're an amoeba. Amoebas have these eye-like cores (or something like that, I don't know biology), and you have two of 'em. You control one with WASD and the other with IJKL. There has to be a constant radius of stuff around each of the cores: And the area of the amoeba has to stay constant. So if you move a core in one direction, you increase the amoeba's area, but that increase is compensated by a decrease somewhere else: Aaaaaand I'd like to implement a vagination mechanic. You absorb things by engulfing them, like a boss. Maybe even an extra core, or a needle that pops you and causes all your inner stuff to start gushing out: But here's the problem: I don't know how to make this. However, I would like some ideas on how to implement it. Should I explore physics libraries like Box2D? Or maybe something involving fluid physics? Any help would be much appreciated. P.S. Feel free to steal this idea. I have plenty of ideas. If you do, please tell me how you made it so I can try it myself.

  • Failing Screen Resize Method

    - by StrongJoshua
    So I want my game to draw to a specific "optimal" size and then be stretched to fit screens that are a different size. I'm using LibGDX and figured that I could just draw everything to a FrameBuffer and then resize that buffer to the appropriate size when drawing it to the actual display. However, my method does not work, it just results in a black screen with the top right quarter of the screen white.Intermediary is the FBO, interMatrix is a Matrix4 object, and camera is an OrthographicCamera. @Override public void render() { // update actors currentStage.act(); //render to intermediary buffer batch.setProjectionMatrix(interMatrix); intermediary.begin(); batch.begin(); currentStage.draw(); batch.flush(); intermediary.end(); //resize to actual width and height Sprite s = new Sprite(intermediary.getColorBufferTexture()); s.flip(true, false); batch.setProjectionMatrix(camera.combined); batch.draw(s.getTexture(), 0, 0, width, height); batch.end(); } These are the constructors for the above mentioned objects (GAME_WIDTH and HEIGHT are the "optimal" settings, width and height are the actual sizes, which are the same when running on desktop). intermediary = new FrameBuffer(Format.RGBA8888, GAME_WIDTH, GAME_HEIGHT, false); interMatrix = new Matrix4(); camera = new OrthographicCamera(width, height); interMatrix.setToOrtho2D(0, 0, GAME_WIDTH, GAME_HEIGHT); Is there a better way of doing this or can is this a viable option and how do I fix what I have?

  • What would be a good game making engine supporting Vector images?

    - by Qqwy
    I want to create a simple platforming game, in which you are a square in a wonderful world. I would like this game to be able to be played in browsers. Basically I am searching for something similar to "Flixel", but with the following features: Support Vector Graphics Allow zooming/rotating objects without producing huge amounts of lag as soon as you are using more objects. (Because I want to rotate the map around the player) So in other words, preferably zoom the viewport/camera instead of the objects themselves. Does an engine like that exist?

  • Double Buffering in Panda3D (C++)

    - by jsvcycling
    How would I go about using Double Buffering (to create a loading screen) in Panda3D using C++? I've searched Google and found some forums that talk about the concept of swapping buffers, but I haven't seen any that show any type of source code (specifically Panda3D/C++). I'd like to try and stay away from using pure OpenGL code and work it through Panda3D, but if I have no other choice, then I'll have to go with OpenGL coding.

  • LWJGL GL_QUADS texture artifact

    - by Dajgoro Labinac
    I managed to get working lwjgl in Java, and i loaded a test image(tv test card), but i keep getting weird artifacts outside the image. Image link: http://tinypic.com/r/vhv9g/6 Code: glBegin(GL_QUADS); glTexCoord2f(0, 0); glVertex2i(10, 10); glTexCoord2f(1, 0); glVertex2i(500, 10); glTexCoord2f(1, 1); glVertex2i(500, 500); glTexCoord2f(0, 1); glVertex2i(10, 500); glEnd(); What could be the cause?

  • Sub-systems in game engines

    - by Hillel
    So here's the problem- I'm writing my own engine library, and it works fine with stuff like menus and the actual game screen. The thing is, I can't really figure out how to integrate something like an intro or dialogue preceding certain levels into this system. Let's look at another example- say I have a game-specific engine which gets a Level object and runs it. Engine would have its own collision and physics system, all hard coded. Now, what if at some point in a level, I want the player to enter a mini-game with different rules? How do I morph the Engine class to support these sub-systems without having to deal with their code all the time (as in: if(regular game) ... else if(mini game) ...)? And what if I want an intro animation at the start of a level, and I want the player to be able to assume control of his character once the animation ends, do I implement the animation into the Engine class itself? Or maybe I need to run another class, CutScene, and when it ends, it calls Engine and starts the level? What if I want to add a dialogue system, where at the start of each level there's a short dialogue and the player can't control his character, and once it ends, he can? Would I then run the dialogue code inside the Engine code? Maybe these sub-systems should all be scripted? I don't know anything about scripting, is it necessary for this kind of situation? Any help would be appreciated.

  • Premultiplying matrices with Perspective destroys them

    - by Shadows In Rain
    If I apply world_to_camera, perspective and camera_to_screen to my mesh, everything is okay. But if I premultiply given matrices (i.e. transform = world_to_camera * perpective * camera_to_screen) before applying, then it seems like only perspective has effect. If it is important... My 3d framework was written from scratch (test project for job interview). But it works flawlessly, or at least I think so. So, question. This is expected behaviour, or my implementation is wrong?

  • Cloning a game and releasing the source

    - by Manux
    I'm not really aware of the legal issues surrounding game clones. I'm around halfway done of making a clone, but it's not just the same gaming concepts, I'm literally using the original game's files (which I do not intend to distribute in any way) in my clone. My original intention was to add features to the game (Firefly studios's first Stronghold) while still using the same art. Is it ok to distribute the source of my clone?

  • Calculating distance from viewer to object in a shader

    - by Jay
    Good morning, I'm working through creating the spherical billboards technique outlined in this paper. I'm trying to create a shader that calculates the distance from the camera to all objects in the scene and stores the results in a texture. I keep getting either a completely black or white texture. Here are my questions: I assume the position that's automatically sent to the vertex shader from ogre is in object space? The gpu interpolates the output position from the vertex shader when it sends it to the fragment shader. Does it do the same for my depth calculation or do I need to move that calculation to the fragment shader? Is there a way to debug shaders? I have no errors but I'm not sure I'm getting my parameters passed into the shaders correctly. Here's my shader code: void DepthVertexShader( float4 position : POSITION, uniform float4x4 worldViewProjMatrix, uniform float3 eyePosition, out float4 outPosition : POSITION, out float Depth ) { // position is in object space // outPosition is in camera space outPosition = mul( worldViewProjMatrix, position ); // calculate distance from camera to vertex Depth = length( eyePosition - position ); } void DepthFragmentShader( float Depth : TEXCOORD0, uniform float fNear, uniform float fFar, out float4 outColor : COLOR ) { // clamp output using clip planes float fColor = 1.0 - smoothstep( fNear, fFar, Depth ); outColor = float4( fColor, fColor, fColor, 1.0 ); } fNear is the near clip plane for the scene fFar is the far clip plane for the scene

  • Adapting Javascript game for mobile

    - by Cardin
    I'm currently developing a Javascript web game for desktop users. It is a sort of tower-defense game that relies on mouse input only, developed on canvas using EaselJS. In the future, or perhaps simultaneously, I would like to adapt the game for mobile devices. I can see at least 3 potential areas in shifting from desktop to mobile: 1. resolution size and UI rearrangement, 2. converting mouse events to touch events, 3. distribution as native app wrapper or mobile Web. What would be the best strategy to facilitate this desktop to mobile conversion? For example, should I try to code the game for both platforms, or port the game UI over to mobile by branching the code base. Should I just publish on the mobile Web or wrap the game in a native app framework? And if I were to code for both platforms using the same codebase, should I register both click and touch events, or remap click events to touch using dispatchEvent?

  • How can I create a flexible system for tiling a 2D RPG map?

    - by CptSupermrkt
    Using libgdx here. I've just finished learning some of the basics of creating a 2D environment and using an OrthographicCamera to view it. The tutorials I went through, however, hardcoded their tiled map in, and none made mention of how to do it any other way. By tiled map, I mean like Final Fantasy 1, where the world map is a grid of squares, each with a different texture. So for example, I've got a 6 tile x 6 tile map, using the following code: Array<Tile> tiles = new Array<Tile>(); tiles.add(new Tile(new Vector2(0,5), TileType.FOREST)); tiles.add(new Tile(new Vector2(1,5), TileType.FOREST)); tiles.add(new Tile(new Vector2(2,5), TileType.FOREST)); tiles.add(new Tile(new Vector2(3,5), TileType.GRASS)); tiles.add(new Tile(new Vector2(4,5), TileType.STONE)); tiles.add(new Tile(new Vector2(5,5), TileType.STONE)); //... x5 more times. Given the random nature of the environment, for loops don't really help as I have to start and finish a loop before I was able to do enough to make it worth setting up the loop. I can see how a loop might be helpful for like tiling an ocean or something, but not in the above case. The above code DOES get me my final desired output, however, if I were to decide I wanted to move a piece or swap two pieces out, oh boy, what a nightmare, even with just a 6x6 test piece, much less a 1000x1000 world map. There must be a better way of doing this. Someone on some post somewhere (can't find it now, of course) said to check out MapEditor. Looks legit. The question is, if that is the answer, how can I make something in MapEditor and have the output map plug in to a variable in my code? I need the tiles as objects in my code, because for example, I determine whether or not a tile is can be passed through or collided with based on my TileTyle enum variable. Are there alternative/language "native" (i.e. not using an outside tool) methods to doing this?

  • Handling game logic events by behavior components

    - by chehob
    My question continues on topic discussed here I have tried implementing attribute/behavior design and here is a quick example demonstrating the issue. class HealthAttribute : public ActorAttribute { public: HealthAttribute( float val ) : mValue( val ) { } float Get( void ) const { return mValue; } void Set( float val ) { mValue = val; } private: float mValue; }; class HealthBehavior : public ActorBehavior { public: HealthBehavior( shared_ptr< HealthAttribute > health ) : pHealth( health ) { // Set OnDamage() to listen for game logic event "DamageEvent" } void OnDamage( IEventDataPtr pEventData ) { // Check DamageEvent target entity // ( compare my entity ID with event's target entity ID ) // If not my entity, do nothing // Else, modify health attribute with received DamageEvent data } protected: shared_ptr< HealthAttribute > pHealth; }; My question - is it possible to get rid of this annoying check for game logic events? In the current implementation when some entity must receive damage, game logic just fires off event that contains damage value and the entity id which should receive that damage. And all HealthBehaviors are subscribed to the DamageEvent type, which leads to any entity possesing HealthBehavior call OnDamage() even if he is not the addressee.

  • XNA 2D Top Down game - FOREACH didn't work for checking Enemy and Switch-Tile

    - by aldroid16
    Here is the gameplay. There is three condition. The player step on a Switch-Tile and it became false. 1) When the Enemy step on it (trapped) AND the player step on it too, the Enemy will be destroyed. 2) But when the Enemy step on it AND the player DIDN'T step on it too, the Enemy will be escaped. 3) If the Switch-Tile condition is true then nothing happened. The effect is activated when the Switch tile is false (player step on the Switch-Tile). Because there are a lot of Enemy and a lot of Switch-Tile, I have to use foreach loop. The problem is after the Enemy is ESCAPED (case 2) and step on another Switch-Tile again, nothing happened to the enemy! I didn't know what's wrong. The effect should be the same, but the Enemy pass the Switch tile like nothing happened (They should be trapped) Can someone tell me what's wrong? Here is the code : public static void switchUpdate(GameTime gameTime) { foreach (SwitchTile switch in switchTiles) { foreach (Enemy enemy in EnemyManager.Enemies) { if (switch.Active == false) { if (!enemy.Destroyed) { if (switch.IsCircleColliding(enemy.EnemyBase.WorldCenter, enemy.EnemyBase.CollisionRadius)) { enemy.EnemySpeed = 10; //reducing Enemy Speed if it enemy is step on the Tile (for about two seconds) enemy.Trapped = true; float elapsed = (float)gameTime.ElapsedGameTime.Milliseconds; moveCounter += elapsed; if (moveCounter> minMoveTime) { //After two seconds, if the player didn't step on Switch-Tile. //The Enemy escaped and its speed back to normal enemy.EnemySpeed = 60f; enemy.Trapped = false; } } } } else if (switch.Active == true && enemy.Trapped == true && switch.IsCircleColliding(enemy.EnemyBase.WorldCenter, enemy.EnemyBase.CollisionRadius) ) { //When the Player step on Switch-Tile and //there is an enemy too on this tile which was trapped = Destroy Enemy enemy.Destroyed = true; } } } }

  • Searching for fast skeletal animation algorithm

    - by igf
    Is it theoretically possible to dynamicaly animate scene with 100-150 400 poly characters meshes on high-end GL ES 2.0 mobile devices or i definetley should use prerendered keyframe animation? Scene have only one light source and precalculated shadow maps. View from top like in Warcraft 3. No any other meshes or objects. 2d collision detecting between objects calculated via spatial hashing. It can be any other algorithm besides ragdoll, but it must supply fast and simple skeletal animation for frame with 100+ low poly meshes for each mesh. Any ideas?

  • Collision detection doesn't work for automated elements in XNA 4.0

    - by NDraskovic
    I have a really weird problem. I made a 3D simulator of an "assembly line" as a part of a college project. Among other things it needs to be able to detect when a box object passes in front of sensor. I tried to solve this by making a model of a laser and checking if the box collides with it. I had some problems with BoundingSpheres of models meshes so I simply create a BoundingSphere and place it in the same place as the model. I organized them into a list of BoundingSpheres called "spheres" and for each model I create one BoundingSphere. All models except the box are static, so the box object has its own BoundingSphere (not a member of the "spheres" list). I also implemented a picking algorithm that I use to start the movement. This is the code that checks for collision: if (spheres.Count != 0) { for (int i = 1; i < spheres.Count; i++) { if (spheres[i].Intersects(PickingRay) != null && Microsoft.Xna.Framework.Input.ButtonState.Pressed == Mouse.GetState().LeftButton) { start = true; break; } if (BoxSphere.Intersects(spheres[i]) && start) { MoveBox(0, false);//The MoveBox function receives the direction (0) and a bool value that dictates whether the box should move or not (false means stop) start = false; break; } if (start /*&& Microsoft.Xna.Framework.Input.ButtonState.Pressed == Mouse.GetState().LeftButton*/ && !BoxSphere.Intersects(spheres[i])) { MoveBox(0, true); break; } } The problem is this: When I use the mouse to move the box (the commented part in the third if condition) the collision works fine (I have another part of code that I removed to simplify my question - it calculates the "address" of the box, and by that number I know that the collision is correct). But when I comment it (like in this example) the box just passes trough the lasers and does not detect the collision (the idea is that the box stops at each laser and the user passes it forth by clicking on the appropriate "switch"). Can you see the problem? Please help, and if you need more informations I will try to give them. Thanks

  • OpenGL depth texture wrong

How to calculate the inner polygon co-ordinates? Edit: I was able to solved the issue by getting the mid-points of all lines. From these mid-points I can move d distance, So I can get three points. No I have 3 points and 3 slopes. From this, I can get three new equations. Simultaneously, solving the equation get the 3 points.

    I've scoured the internet for the last few hours looking for an example of how to run even the most basic OpenGL ES 2 example using JOGL but "by Jupiter!" it has been a total fail. I tried converting the android example from the OpenGL ES 2.0 Programming Guide examples (and at the same time looking at the WebGL example -- which worked fine) yet without any success. Are there any examples out there? If anyone else wants some extra help regarding this question see this thread on the official Jogamp forum.

    In the official Unity Animator State Machine tutorial video animation clips are dragged out from the assets folder into the animator and dropped. I have a 3D model that i bought online to experiment with that comes with animations. I added a custom made animation as well. These all work well in my demo project. But when i add a animator to the assets and try to drag and drop animations onto it it doesnt work. I get a forbidden-sign as a mouse pointer. I try to add animations through the inspector but that does not work either. The tutorials makes it seem so easy and does not talk anything about what animations can be used. What am i doing wrong?

    In my game I use particle effect for various purposes. In that I detect the completion of the particle effect. Basically I want to do something after completion of the particle effect. But the problem is that I didn't able to find the particle effect completion. So any community member please help me. EDIT : I was creating particle effect using following code pointParticleEmtitter = new PointParticleEmitter(pX, pY); particleSystem = new ParticleSystem(pointParticleEmtitter, maxRate, minRate, maxParticles, mParticleTextureRegion.deepCopy()); particleSystem.setBlendFunction(GL10.GL_SRC_ALPHA, GL10.GL_ONE); particleSystem.addParticleInitializer(new ColorInitializer(0f, 0f, 1f)); particleSystem.addParticleModifier(new AlphaModifier(1, 0, 0, 0.5f)); particleSystem.addParticleModifier(new ExpireModifier(0.5f)); gameObject.getScene().attachChild(particleSystem); Using above code the particle effect was started but when finished that I want to detect. After finishing effect I want to remove the object from the scene.

    How this kind of effects are technically implemented using OpenGL ES? Are they performing simulation on GPU (using Shaders) or CPU while using some smart vertex positioning and texturing? Why it appears so fast (in terms of performance)?

  • How to detect GLSL warnings?

    - by msell
    After compiling a shader with glCompileShader, I can call glGetShaderiv with GL_COMPILE_STATUS to check if the shader compiled successfully. I can also call glGetShaderInfoLog to get information about possible errors, warnings or other info. The information log returned by this function is unspecified. In a tool where users can write their own shaders, I would like to print all errors and warnings from the compilation, but nothing if no warnings or errors were found. The problem is that the GL_COMPILE_STATUS returns only false if the compilation failed and true otherwise. If no problems were found, some drivers return empty info log from glGetShaderInfoLog, but some drivers can return something else such as "No errors.", which I do not want to print to the user. How is this problem generally solved?
