  • Farseer circle hangs where it's spawned

    - by necrosmash
    I'm currently trying to simply spawn a circle in Farseer. However, it's stuck wherever I spawn it! The game is updating fine, as I can see the circle spinning in place when I spawn it because of how I currently have gravity set up (following code from Game1.cs): // Initialise the screen center for use with // the Level class screenCenter = new Vector2(graphics.GraphicsDevice.Viewport.Width / 2f, graphics.GraphicsDevice.Viewport.Height / 2f); world = new World(new Vector2(20, 20)); currentLevel = new Level1(screenCenter, circleSprite, groundSprite, ref world); Level1 constructor: public Level1(Vector2 screenCenter, Texture2D circleSprite, Texture2D groundSprite, ref World world) { player = new Player(ref world, screenCenter, circleSprite); ground = new Ground(ref world, screenCenter, groundSprite); listLevelItems = new List<LevelItem>(); listLevelItems.Add(player); listLevelItems.Add(ground); } Player constructor: public Player(ref World world, Vector2 screenCenter, Texture2D sprite) { setSprite(sprite); setPosition((screenCenter / MeterInPixels) + new Vector2(0f, 0f)); playerBody = BodyFactory.CreateCircle(world, 96f / (2f * MeterInPixels), 1f, playerPosition); getBody().BodyType = BodyType.Dynamic; // Ball bounce and friction getBody().Restitution = 0.3f; getBody().Friction = 0.5f; } If I use a breakpoint and change the playerBody position while the game is halted, the ball does move, but stays fixed in its new location. Any help would be greatly appreciated.

  • Help with collision detection method [on hold]

    - by derek jones
    I was wondering if any of you could spare me some time to go over some collision detection on my platform engine. i tried XNA a few years back but for reasons i wont go into online could not continue, my health is now at a state where i am ready to try again but due to my current circumstances (and age) schooling is out of the question so i turn to you guys for help. Whilst i can adapt the MS sample ok and have some great features, you will agree modifying code is not really learning. So i have spent the last couple of week going over my old MS code and lots of stuff online and decided on what i want and have ported most of it over to code that i understand 90% of. I have my player class that moves about, jumps with gravity, has animations and a bounding box that follows it around. I have my map & basic level class to load levels from text files. Its just how i handle the collisions that i am struggling with as i will want per pixel collision on some tiles(i have code for this in a pong game i made so that should be ok). I'm pretty clear in my mind on what i need to do its just putting it in code and in the right place, here's what i was thinking. I was going to do it all in layers, have a tile layer, a collision layer & an item layer this way i could make a nice map editor in Win Forms at some point. Anyway i need to read in the collision layer the assign each tile a rectangle and collision property, and this is where i get me. Would any of you be able to spare some time and go over this with me ? I will post some code later Regards Del

  • Collision Detection within Player/Enemy Class

    - by user1264811
    I'm making a 2D platform game. Right now I'm just working on making a very generic Player class. I'm wondering if it would be more efficient/better practice to have an ActionListener within the Player class to detect collisions with Enemy objects (also have an ActionListener) or to handle all the collisions in the main world. Furthermore, I'm thinking ahead about how I will handle collisions with the platforms themselves. I've looked into the double boolean arrays to see which tiles players can go to and which they can't. I don't understand how to use this class and the player class at the same time. Thank you.

  • Options for 2D Web/iPhone/Android, with Test Framework

    - by ashes999
    I would like to make a 2D game with one codebase that runs on iPhone, Android, and web (any flavour of web -- HTML5, Flash, Silverlight, etc.) What are my options? I should be able to write my code once, and run it anywhere. I also absolutely need the ability to write unit tests (or write a unit-testing framework) -- I cannot make sizable games without testing. Unity is good, but unity is 3d; even with hacks, the graphical assets will still be 3d. I'm after 2d, not 3d. (If you need a Mac or separate licensing for the Mac part, that's okay.)

  • How to build a "traffic AI"?

    - by Lunikon
    A project I am working on right now features a lot of "traffic" in the sense of cars moving along roads, aircraft moving aroun an apron etc. As of now the available paths are precalculated, so nodes are generated automatically for crossings which themselves are interconnected by edges. When a character/agent spawns into the world it starts at some node and finds a path to a target node by means of a simply A* algorithm. The agent follows the path and ultimately reaches its destination. No problem so far. Now I need to enable the agents to avoid collisions and to handle complex traffic situations. Since I'm new to the field of AI I looked up several papers/articles on steering behavior but found them to be too low-level. My problem consists less of the actual collision avoidance (which is rather simple in this case because the agents follow strictly defined paths) but of situations like one agent leaving a dead-end while another one wants to enter exactly the same one. Or two agents meeting at a bottleneck which only allows one agent to pass at a time but both need to pass it (according to the optimal route found before) and they need to find a way to let the other one pass first. So basically the main aspect of the problem would be predicting traffic movement to avoid dead-locks. Difficult to describe, but I guess you get what I mean. Do you have any recommendations for me on where to start looking? Any papers, sample projects or similar things that could get me started? I appreciate your help!

  • Is it possible to create an "impossible" rooms in games?

    - by qwerty3000
    Forgive me my lack of knowlegde, but for quite a long time I asked myself whether it was possible to create a continous game space that some player could walk inside and so on, that would be absolutely impossible in reality, e.g. you have a very small house that allows you to go around it to see all sides and the full dimensions, and then, when you enter, it is like a giant hall, without any loading screen or (internal) "model change" and so on. I'm no game designer and I never needed to learn 3D-modelling, so I don't know what is possible and what isn't. And is this the same as Is the "impossible object" possible in computer graphics? this? Or is it just the same category, but not exactly the same question? Thanks.

  • UnityEngine.Vector2 does not contian a definition for "Set".... using futile

    - by FreshJays
    I am a bit lost, I am using futile and I am just trying to run the demo. But I keep getting UnityEngine.Vector2 does not contian a definition for "Set" in just one class, my using statments are: using System; using UnityEngine; using System.Collections; using System.Collections.Generic; When I look at the documents, I see that Set is a function http://docs.unity3d.com/Documentation/ScriptReference/Vector2.html I am using version 3.4.2 (in futile its happening in just the FAtlas class)

  • Alternative ways to construct maps

    - by sideways8
    I've searched around and it seems like most people are using tile-based map systems. I suppose this question is more theoretical than practical (I am not very concerned about memory or performance speed), but I want to know: what other ways can a map be created in a game? A map being a graphic representation of terrain that can be navigated, has entrances and exits, and boundares (no-go zones). Besides using text files to store and arrays to load tile data, one idea I had was to store a map entirely as a graphic file and use queries on the pixel colour to determine boundaries (ie, you can only move in a certain direction if the way is bright enough in that direction). What other creative map systems are out there?

  • Which is better a computer science degree or a Software engineer degree?

    - by Shadow wolf
    I'm asking here so since you all have experience in or around game programming, that's what I want to do, and I’m trying to find as many options as I can before my senior year, which is next year. So do you have any opinions on the matter of which would give me a better education in programming? Please no talking about anything other than the two degrees because I know of game programming degrees out there but I like to see which of these would provide the best alternate choice.

  • Using 2d collision with 3d objects

    - by Lyise
    I'm planning to write a fairly basic scrolling shoot 'em up, however, I have run into a query with regards to checking for collision. I plan to have a fixed top down view, where the player and enemies are all 3d objects on a fixed plane, and when the enemy or player fires at the other, their shots will also be along this fixed plane. In order to handle the collision, I have read up a bit on collision detection in 3d, as it is not something I have looked into previously, but I'm not sure what would be ideal for this situation. My options appear to be: Sphere collision, however, this lacks the pixel precision I would like Detection using all vertexes and planes of each object, but this seems overly convoluted for a fixed plane of play Rendering the play screen in black and white (where white is an object, black is empty space), once for enemies and once for the player, and checking for collisions that way (if a pixel is white on both, there is a collision) Which of these would be the best approach, or is there another option that I am missing? I have done this previously using 2d sprites, however I can't use the same thinking here as I don't have the image to refer to.

  • Is it safe to run multiple XNA ContentManager instances on multiple threads?

    - by Boinst
    My XNA project currently uses one ContentManager instance, and one dedicated background thread for loading all content. I wonder, would it be safe to have multiple ContentManager instances, each in it's own dedicated thread, loading different content at the same time? I'm prompted to ask this question because this article makes the following statement: If there are two textures created at the same time on different threads, they will clobber the other and you will end up with some garbage in the textures. I think that what the author is saying here, is that if I access one ContentManager simultaneously on two threads, I'll get garbage. But what if I have separate ContentManager instances for each thread? If no-one knows the answer already from experience, I'll go ahead and try it and see what happens.

  • How can I calculate the angle between two 2D vectors?

    - by Error 454
    I am working on some movement AI where there are no obstacles and movement is restricted to the XY plane. I am calculating two vectors, v, the facing direction of ship 1, and w, the vector pointing from the position of ship 1 to ship 2. I am then calculating the angle between these two vectors using the formula arccos((v · w) / (|v| · |w|)) The problem I'm having is that arccos only returns values between 0° and 180°. This makes it impossible to determine whether I should turn left or right to face the other ship. Is there a better way to do this?

  • Error when updating enumerated value?

    - by igrad
    Once upon a time, there was a Player class (simplified version) enum animState{RUNNING,JUMPING,FALLING,IDLING}; class Player { public: Player(int x, int y); void handle(); void show(); ~Player(); private: int m_x; int m_y; animState playerAnimState; } There was also a "handle" function-member, which took care of all movement and collisions for the player: #include "player.h" void Player::handle() { if(/*Player presses 'D' key*/) { m_x++; playerAnimState = RUNNING; } //Other stuff that is just there to look nice Through lots of experimentation with "//" and "/**/", I've found that I consistently get an error at "playerAnimState = RUNNING." Have I broken some enumeration rule? Does my laptop really suck that bad? I hate to post a "fix my code for me" question, but I'm not very seasoned with enums.

  • Managing game objects/components

    - by Xeon06
    Good day everyone, By far the biggest problem that has always dawned on my when programming games is how to structure my code. It just becomes an incredible mess after a while. The reason for that is because I have no idea how different classes should interact with each other. Let's have an example. Say I have a class Player, a class PlayerInput and a class Map. The player class contains information as to the location of the player, whereas the player input class handles changing that location, but by first making sure it's within a walkable area from the map class. How to structure this? My usual approach is to pass those components as parameters in the constructors of the parameters that need them, like so: var map = new Map(); var player = new Player(); var input = new PlayerInput(player, map); The problem with that is that it quickly gets messy, when you add new components you have to go through your constructors and update them, and it doesn't work well if you have mirroring references: var physics = new Physics(input); //Oops, doesn't work var input = new Input(physics); So, how do you guys usually manage this? Thanks.

  • How can I use an object pool for optimization in AndEngine?

    - by coder_For_Life22
    I have read up on a tutorial that allows you to reuse sprites that are re-added to the scene such as bullets from a gun or any other objects using an ObjectPool. In my game i have a variation of sprites about 6 all together with different textures. This is how the object pool is set up with its own class extending Java's GenericPool class public class BulletPool extends GenericPool<BulletSprite> { private TextureRegion mTextureRegion; public BulletPool(TextureRegion pTextureRegion) { if (pTextureRegion == null) { // Need to be able to create a Sprite so the Pool needs to have a TextureRegion throw new IllegalArgumentException("The texture region must not be NULL"); } mTextureRegion = pTextureRegion; } /** * Called when a Bullet is required but there isn't one in the pool */ @Override protected BulletSprite onAllocatePoolItem() { return new BulletSprite(mTextureRegion); } /** * Called when a Bullet is sent to the pool */ @Override protected void onHandleRecycleItem(final BulletSprite pBullet) { pBullet.setIgnoreUpdate(true); pBullet.setVisible(false); } /** * Called just before a Bullet is returned to the caller, this is where you write your initialize code * i.e. set location, rotation, etc. */ @Override protected void onHandleObtainItem(final BulletSprite pBullet) { pBullet.reset(); } } As you see here it takes a TextureRegion parameter. The only problem i am facing with this is that i need to have 6 different sprites recycled and reused in the ObjectPool. This ObjectPool is set up to only use one TextureRegion. Any idea's or suggestions on how to do this?

  • Problem texturing with opengl

    - by Killrazor
    Hello! I'm having problems making a simple sprite rendering. I load 2 different textures. Then, I bind these textures and draw 2 squares, one with each texture. But only the texture of the first rendered object is drawn in both squares. Its like if I'd only use a texture or as if glBindTexture don't work properly. I know that GL is a state machine, but I think that you only need to change active texture with glBindTexture. I load texture with this method: bool CTexture::generate( utils::CImageBuff* img ) { assert(img); m_image = img; CHECKGL(glGenTextures(1,&m_textureID)); CHECKGL(glBindTexture(GL_TEXTURE_2D,m_textureID)); CHECKGL(glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR)); CHECKGL(glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR)); //CHECKGL(glTexImage2D(GL_TEXTURE_2D,0,img->getBpp(),img->getWitdh(),img->getHeight(),0,img->getFormat(),GL_UNSIGNED_BYTE,img->getImgData())); CHECKGL(glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, img->getWitdh(), img->getHeight(), 0, GL_RGBA, GL_UNSIGNED_BYTE, img->getImgData())); return true; } And I bind textures with this function: void CTexture::bind() { CHECKGL(glBindTexture(GL_TEXTURE_2D,m_textureID)); } Also, I draw sprites with this method void CSprite2D::render() { CHECKGL(glLoadIdentity()); CHECKGL(glEnable(GL_TEXTURE_2D)); CHECKGL(glEnable(GL_BLEND)); CHECKGL(glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA)); m_texture->bind(); CHECKGL(glPushMatrix()); CHECKGL(glBegin(GL_QUADS)); CHECKGL(glTexCoord2f(m_textureAreaStart.s,m_textureAreaStart.t)); // 0,0 by default CHECKGL(glVertex3i(m_position.x,m_position.y,0)); CHECKGL(glTexCoord2f(m_textureAreaEnd.s,m_textureAreaStart.t)); // 1,0 by default CHECKGL(glVertex3i( m_position.x + m_dimensions.x, m_position.y, 0)); CHECKGL(glTexCoord2f(m_textureAreaEnd.s, m_textureAreaEnd.t)); // 1,1 by default CHECKGL(glVertex3i( m_position.x + m_dimensions.x, m_position.y + m_dimensions.y, 0)); CHECKGL(glTexCoord2f(m_textureAreaStart.s, m_textureAreaEnd.t)); // 0,1 by default CHECKGL(glVertex3i( m_position.x, m_position.y + m_dimensions.y,0)); CHECKGL(glPopMatrix()); CHECKGL(glDisable(GL_BLEND)); } Could you help me? All help is welcome. Thanks!!

  • What is "top new free" on GooglePlay

    - by Lumis
    On Android Market i.e. GooglePlay, there used to be a page with the latest new games. So every game had a chance to get noticed and make its way up especially if it was good. But now I see "top new free" page and no more the latest apps. I don't understand how can be "top new" Anybody knows how this works? If there are no more pages with the very latest uploaded games then the new apps will be barely seen to exist even if they are excellent, and new programmers have very little chance of getting noticed. Any good advice how to promote a new Android app these days?

  • How to properly code in Unity? [on hold]

    - by Vincent B.
    I'm fairly new to Unity (yet I touched it and made a few proto with it) and I'd like to know how I'm supposed to work with it. I'm student in programming so I'm used to C/C++ with SDL/SFML, writing code and only using Input/Graphics/Network libs. I followed a few Unity guides and it was way more around drag & drop on scenes and a bit of scripting to activate it all, which disturbed me. So I fond a way to only use one GameObject and use a Singleton to launch code and display stuff (for 2d games at least). At the end of the day I make games not using "Instantiate" or such at all. Is it the right way ? Am I supposed to do this ? How much are your scenes populated (in a professional environment) ? When should I stop coding and start using the editor ?

  • Rotate triangle so that its tip points in the direction of the point on the screen that we last touched

    - by Sid
    OpenGL ES - Android. Hello all, I am unable to rotate the triangle accordingly in such a way that its tip always points to my finger. What i did : Constructed a triangle in by GL.GL_TRIANGLES. Added touch events to it. I can rotate the triangle along my Z-axis successfully. Even made the vector class for it. What i need : Each time when I touch the screen, I want to rotate the triangle to face the touch point. Need some help. Here's what i implemented. I wonder that where i am going wrong? My code : public class Graphic2DTriangle { private FloatBuffer vertexBuffer; private ByteBuffer indexBuffer; private float[] vertices = { -1.0f,-1.0f, 0.0f, 2.0f, 0.0f, 0.0f, -1.0f, 1.0f, 0.0f }; private byte[] indices = { 0, 1, 2 }; public Graphic2DTriangle() { ByteBuffer vbb = ByteBuffer.allocateDirect(vertices.length * 4); vbb.order(ByteOrder.nativeOrder()); // Use native byte order vertexBuffer = vbb.asFloatBuffer(); // Convert byte buffer to float vertexBuffer.put(vertices); // Copy data into buffer vertexBuffer.position(0); // Rewind // Setup index-array buffer. Indices in byte. indexBuffer = ByteBuffer.allocateDirect(indices.length); indexBuffer.put(indices); indexBuffer.position(0); } public void draw(GL10 gl) { gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); gl.glVertexPointer(3, GL10.GL_FLOAT, 0, vertexBuffer); gl.glDrawElements(GL10.GL_TRIANGLES, indices.length, GL10.GL_UNSIGNED_BYTE, indexBuffer); gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); } } My SurfaceView class where i've done some Touch Events. public class BallThrowGLSurfaceView extends GLSurfaceView{ MySquareRender _renderObj; View _viewObj; float oldX,oldY,dX,dY; final float TOUCH_SCALE_FACTOR = 0.6f; Vector2 touchPos = new Vector2(); float angle=0; public BallThrowGLSurfaceView(Context context) { super(context); // TODO Auto-generated constructor stub _renderObj = new MySquareRender(context); this.setRenderer(_renderObj); this.setRenderMode(RENDERMODE_WHEN_DIRTY); } @Override public boolean onTouchEvent(MotionEvent event) { // TODO Auto-generated method stub touchPos.x = event.getX(); touchPos.y = event.getY(); Log.i("Co-ord", touchPos.x+"hh"+touchPos.y); switch(event.getAction()){ case MotionEvent.ACTION_MOVE : dX = touchPos.x - oldX; dY = touchPos.y - oldY; if(touchPos.y > getHeight()/2){ dX = dX*-1; } if(touchPos.x < getWidth()/2){ dY = dY*-1; } _renderObj.mAngle += (dX+dY) * TOUCH_SCALE_FACTOR; requestRender(); Log.i("AngleCo-ord", _renderObj.mAngle +"hh"); } oldX = touchPos.x; oldY = touchPos.y; Log.i("OldCo-ord", oldX+" hh "+oldY); return true; } } Last but not the least.

I can rotate the triangle with the touch of my finger. But i want that ONE VERTEX of the triangle should point at my finger position respective of the position of my finger.

  • How to find 2D grid cells swept by a moving circle?

    - by Nevermind
    I'm making a game based on a 2D grid, with some cells passable and some not. Dynamic objects can move continuously, independent of the grid, but need to collide with impassable cells. I wrote an algorithm to trace a ray against the grid, that gives me all cells that ray intersects. However, actual object are not point-sized; I'm currently representing them as circles. But I can't figure out an effective algorithm to trace a moving circle. Here's a picture of what I need: The numbers show in what order the circle collides with grid cells. Does anybody know the algorithm to find these collisions? Preferably in C#. Update The circle can be bigger than a single grid cell.

What I have in mind is basically just a 2-player game witch you can play with 2 phones over local area connection/WiFi. Both phones need to be able to pass 3 integer values to the other phone in real time. So far I have considered using Socket's, but before I dig into it too deep I wanted to ask if there might be a better approach? Thanks!

  • Algorithm to zoom a plotted function

    - by astinx
    I'm making a game in android and I need plot a function, my algorithm is this: @Override protected void onDraw(Canvas canvas) { float e = 0.5f; //from -x axis to +x evaluate f(x) for (float x = -z(canvas.getWidth()); x < z(canvas.getWidth()); x+=e) { float x1,y1; x1 = x; y1 = f(x); canvas.drawPoint((canvas.getWidth()/2)+x1, (canvas.getHeight()/2)-y1, paintWhite); } super.onDraw(canvas); } This is how it works. If my function is, for example f(x)=x^2, then z(x) is sqrt(x). I evaluate each point between -z(x) to z(x) and then I draw them. As you can see I use the half of the size of the screen to put the function in the middle of the screen. The problem isn't that the code isn't working, actually plots the function. But if the screen is of 320*480 then this function will be really tiny like in the image below. My question is: how can I change this algorithm to scale the function?. BTW what I'm really wanting to do is trace a route to later display an animated sprite, so actually scale this image doesnt gonna help me. I need change the algorithm in order to draw the same interval but in a larger space. Any tip helps, thanks! Current working result Desired result UPDATE: I will try explain more in detail what the problem is. Given this interval [-15...15] (-z(x) to z(x)) I need divide this points in a bigger interval [-320...320] (-x to x). For example, when you use some plotting software like this one. Although the div where is contain the function has 640 px of width, you dont see that the interval is from -320 to 320, you see that the interval is from -6 to 6. How can I achieve this?

  • SDL: How would I add tile layers with my area class as a singleton?

    - by Tony
    I´m trying to wrap my head around how to get this done, if at all possible. So basically I have a Area class, Map class and Tile class. My Area class is a singleton, and this is causing some confusion. I´m trying to draw like this: Background / Tiles / Entities / Overlay Tiles / UI. void C_Application::OnRender() { // Fill the screen black SDL_FillRect( Surf_Screen, &Surf_Screen->clip_rect, SDL_MapRGB( Surf_Screen->format, 0x00, 0x00, 0x00 ) ); // Draw background // Draw tiles C_Area::AreaControl.OnRender(Surf_Screen, -C_Camera::CameraControl.GetX(), -C_Camera::CameraControl.GetY()); // Draw entities for(unsigned int i = 0;i < C_Entity::EntityList.size();i++) { if( !C_Entity::EntityList[i] ) { continue; } C_Entity::EntityList[i]->OnRender( Surf_Screen ); } // Draw overlay tiles // Draw UI // Update the Surf_Screen surface SDL_Flip( Surf_Screen); } Would be nice if someone could give a little input. Thanks.

  • Retrieve the coordinates of the *occluding* (closest/drawn) pixels during 3D overlap, using OpenGL?

    - by Big Rich
    Hi, Sorry if the question is not worded well, I'm a new to both 3D and OpenGL. How could I go about obtaining the 3D coordinates of the occluding object, at the point where occlusion is happening (i.e. the 'intersection' of the object in front/closest to the screen)? Just to offer a [very] rudimentary, visual, example, if you were to form an index-finger cross, with your right hand closest to your face, I'd like to know the coordinates of the part of your right finger which obscures the other finger (obviously back within the OpenGL context - no jokers ;-) ). If there is a way to find out both about the occluder (hider) and the occluded (hidden) objects in OpenGL, then that would be of great use, also. Cheers Rich
