  • Drawing a line using openGL does not work

    - by vikasm
    I am a beginner in OpenGL and tried to write my first program to draw some points and a line. I can see that the window opens with white background but no line is drawn. I was expecting to see red colored (because glColor3f(1.0, 0.0, 0.0);) dots (pixels) and line. But nothing is seen. Here is my code. void init2D(float r, float g, float b) { glClearColor(r,g,b,0.0); glMatrixMode(GL_PROJECTION); gluOrtho2D(0.0, 200.0, 0.0, 150.0); } void display() { glClear(GL_COLOR_BUFFER_BIT); glColor3f(1.0, 0.0, 0.0); glBegin(GL_POINTS); for(int i = 0; i < 10; i++) { glVertex2i(10+5*i, 110); } glEnd(); //draw a line glBegin(GL_LINES); glVertex2i(10,10); glVertex2i(100,100); glEnd(); glFlush(); } int main(int argc, char** argv) { //Initialize Glut glutInit(&argc, argv); //setup some memory buffers for our display glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB); //set the window size glutInitWindowSize(500, 500); //create the window with the title 'points and lines' glutCreateWindow("Points and Lines"); init2D(0.0, 0.0, 0.0); glutDisplayFunc(display); glutMainLoop(); } I wanted to verify that the glcontext was opening properly and used this code: int main(int argc, char **argv) { glutInit(&argc, argv); //setup some memory buffers for our display glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB); //set the window size glutInitWindowSize(500, 500); //create the window with the title 'points and lines' glutCreateWindow("Points and Lines"); char *GL_version=(char *)glGetString(GL_VERSION); puts(GL_version); char *GL_vendor=(char *)glGetString(GL_VENDOR); puts(GL_vendor); char *GL_renderer=(char *)glGetString(GL_RENDERER); puts(GL_renderer); getchar(); return 0; } And the ouput I got was: 3.1.0 - Build 8.15.10.2345 Intel Intel(R) HD Graphics Family Can someone point out what I am doing wrong ? Thanks.

  • ArrayList of Entites Random Movement

    - by opiop65
    I have an arraylist of entites that I want to move randomly. No matter what I do, they won't move. Here is my female class: import java.awt.Graphics2D; import java.awt.Image; import java.awt.Rectangle; import java.util.Random; import javax.swing.ImageIcon; public class Female extends Entity { static int femaleX = 0; static int femaleY = 0; double walkSpeed = .1f; Random rand = new Random(); int random; int dir; Player player; public Female(int posX, int posY) { super(posX, posY); } public void update() { posX += femaleX; posY += femaleY; } public void draw(Graphics2D g2d) { g2d.drawImage(getFemaleImg(), posX, posY, null); if (Player.showBounds == true) { g2d.draw(getBounds()); } } public Image getFemaleImg() { ImageIcon ic = new ImageIcon("res/female.png"); return ic.getImage(); } public Rectangle getBounds() { return new Rectangle(posX, posY, getFemaleImg().getHeight(null), getFemaleImg().getWidth(null)); } public void moveFemale() { random = rand.nextInt(3); System.out.println(random); if (random == 0) { dir = 0; posX -= (int) walkSpeed; } } } And here is how I update the female class in the main class: public void actionPerformed(ActionEvent ae) { player.update(); for(int i = 0; i < females.size(); i++){ Female tempFemale = females.get(i); tempFemale.update(); } repaint(); } If I do something like this(in the female update method): public void update() { posX += femaleX; posY += femaleY; posX -= walkSpeed; } The characters move with no problem. Why is this?

  • (Android) How are OpenGL ES 1 framebuffers and textures sized?

    - by jens
    I am trying to draw to a texture using a framebuffer using OpenGL ES 1.1 on Android, Java. Afterwords I want to overlay this texture full-screen over my game. In theory, this works like a charm, but somehow the coordinates are off. For testing I drew something at (0,0) with width and height 200, and it partly is off-screen. This is how I create the framebuffer: fb = new int[1]; depthRb = new int[1]; renderTex = new int[1]; gl11ep.glGenFramebuffersOES(1, fb, 0); gl11ep.glGenRenderbuffersOES(1, depthRb, 0); // the depth buffer gl.glGenTextures(1, renderTex, 0);// generate texture gl.glBindTexture(GL10.GL_TEXTURE_2D, renderTex[0]); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_REPEAT); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_REPEAT); texBuffer = ByteBuffer.allocateDirect(buf.length*4).order(ByteOrder.nativeOrder()).asIntBuffer(); gl.glTexImage2D(GL10.GL_TEXTURE_2D, 0, GL10.GL_LUMINANCE, texW, texH, 0, GL10.GL_LUMINANCE, GL10.GL_UNSIGNED_BYTE, texBuffer); gl11ep.glBindRenderbufferOES(GL11ExtensionPack.GL_RENDERBUFFER_OES, depthRb[0]); gl11ep.glRenderbufferStorageOES(GL11ExtensionPack.GL_RENDERBUFFER_OES, GL11ExtensionPack.GL_DEPTH_COMPONENT16, texW, texH); Before I draw, I do this: gl11ep.glBindFramebufferOES(GL11ExtensionPack.GL_FRAMEBUFFER_OES, fb[0]); gl.glClearColor(0f, 0f, 0f, 0f); // specify texture as color attachment gl11ep.glFramebufferTexture2DOES(GL11ExtensionPack.GL_FRAMEBUFFER_OES, GL11ExtensionPack.GL_COLOR_ATTACHMENT0_OES, GL10.GL_TEXTURE_2D, renderTex[0], 0); // attach render buffer as depth buffer gl11ep.glFramebufferRenderbufferOES(GL11ExtensionPack.GL_FRAMEBUFFER_OES, GL11ExtensionPack.GL_DEPTH_ATTACHMENT_OES, GL11ExtensionPack.GL_RENDERBUFFER_OES, depthRb[0]); I set texW = 1024 and texH = 512. When rendering this texture fullscreen, with a lightmask (size 200x200) placed at (0, 0) and (texW/2, texH/2). You can see that it seems like the coordinate system doesnt start at (0,0) as that light overlaps the screen and the images are not drawn as squares (my lightcone-texture is a circle, not an ellipse). So, how is the coordinate system of this offscreen-drawn texture defined? Thanks

  • How to chain actions/animations together and delay their execution?

    - by codinghands
    I'm trying to build a simple game with a number of screens - 'TitleScreen', 'LoadingScreen', 'PlayScreen', 'HighScoreScreen' - each of which has it's own draw & update logic methods, sprites, other useful fields, etc. This works well for me as a game dev beginner, and it runs. However, on my 'PlayScreen' I want to run some animations before the player gets control - dropping in some artwork, playing some sound effects, generally prettifying things a little. However, I'm not sure what the best way to chain animations / sound effects / other timed general events is. I could make an intermediary screen, 'PrePlayScreen', which simply has all of this hardcoded like so: Update(){ Animation anim1 = new Animation(.....); Animation anim2 = new Animation(.....); anim1.Run(); if(anim1.State == AnimationState.Complete) anim2.Run(); if(anim2.State == AnimationState.Complete) // Load 'PlayScreen' screen } But this doesn't seem so great - surely their must be a better way? I then thought, 'Hey - an AnimationManager! That'd be awesome!'. But then that creeping OOP panic set in as I thought about it some more. If I create the Animation in my Screen, then add it to the AnimationManager (which may or may not be a GameComponent hooked up to Update/Draw), how can I get 'back' to it? To signal commands like start / end / repeat? I'd still need to keep a reference to the object in my Screen so that I could still communicate with it once it's buried in the bosom of a List in my AnimationManager. This seems bad. I've also tried using events - call 'Update' on all the animations in the PlayScreen update loop, but crucially all of the animations have a bool flag ('Active') which determines whether they should begin. The first animation has this set to 'true', all others 'false'. On completion the first animation raises an event, which sets animation 2's bool flag to true (and so it then runs). Once animation 2 is complete another 'anim complete' event is raised, and the screen state changes. Considering the game I'm making is basically as simple as it gets I know I'm overthinking this... it's just the paradigm shift from web - game development is making me break out in a serious case of the stupids.

  • Position sprite at center of screen

    - by Wellie
    I am trying to get a sprite to position itself at the center of the screen but nothing seems to be working for me. I'm trying Viewport viewport = graphics.GraphicsDevice.Viewport; logoPosition = new Vector2((viewport.Width - towerImage.Width) / 2, (viewport.Height - towerImage.Height) / 2); and spriteBatch.Draw(towerImage, centre, null, Color.White, 0, baseOrigin, 1.0f, SpriteEffects.None, 0); This is my first time using XNA and I don't really have a clue what I'm doing.

  • 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!!

  • MVC Can the model know ANYTHING about the view?

    - by AwDogsGo2Heaven
    I'm working on a game, and without getting into any details I am using MVC "patterns", "rules" or whatever you want to call it to make the game. The view includes everything needed to draw things on the screen, the controller passes input to the model. And the Model contains game logic. Here's my problem, the game is being made for mobile devices that vary in screen sizes. I feel my model needs to know the view size so it can appropriately adjust for it. I've thought about it for a while I could put all the adjustments in the view, but it just seems inefficient to translate the model positioning to the view's needed positioning every time. If the model knows the size it only needed to adjust itself once. So my question is can I pass the view size to the model without 'breaking' MVC? I feel personally they are still decoupled this way because a size is just a number, I could still change the view any time as long as it has a size. But I wanted to get a community response on this because I haven't seen many discussions of MVC being used in a game. (And to be clear I don't want an answer of why I shouldn't use it in a game, but do I break MVC by letting it know the view's size) EDIT - More details on the game's needs and why I wanted to pass the view. Some objects positions need to be set relative to the edge of the screen (such as UI elements) so that they appear relatively in the same place. Sprite sizes are not stretched if the window size is wider such as an IPhone 5 screen. They will just be placed relatively to the screen edge. .If I gave it to the view to handle this, I will need a flag saying that this element is positioned say x number of pixels from TOP BOTTOM RIGHT LEFT. Then allow the view to draw it with that information. Its acceptable, I just wanted to know if there was a better way while still being MVC because it seems this way will be repeating a logic over and over, where as if I knew the view size in the model, I could convert all the relative positions into absolute positions in one run, but with this I have to convert on every update to the screen.

  • Powerpoint not drawing in slide properly...

    - by commradepolski
    So got another issue to post about. I have a user here who uses powerpoint a lot, Office 07 with SP2. When he opens up the presentation, powerpoint opens fine without errors, but does not draw in the main slide properly. So to better explain that, the list on the left hand side, that shows the slides and what order they are in, loads up fine. You can see the slides and the content etc. When you click on a slide, to edit it, it does not draw in on the editing screen. Not really sure how to explain that. The screen where the work on the slide is done, is what is affected. This is a screen shot from my pc not the users. So instead of the screen saying "Click to add title" it would be improperly drawn such that if I were to drag an explorer window across it, it would leave a trail. I have tried reinstalling office, updating it, as well as giving the user a new windows image and nothing has helped. Any help or advice is appreciated.

  • adding onTap method on path direction between 2 point

    - by idham
    I have a problem in my Android application I have a path direction on my application and I want to add an onTap method for the path, so if I touch that path my application will display information with alert dialog. This my activity code: hasilrute hr = new hasilrute(); for (int k = 0;k < hr.r2.size(); k++){ String angkot = hr.r2.get(i).angkot; Cursor c = db.getLatLong(hasilrute.a); Cursor cc = db.getLatLong(hasilrute.b); String x = (c.getString(3)+","+c.getString(2)); String xx = (cc.getString(3)+","+cc.getString(2)); String pairs[] = getDirectionData(x, xx); String[] lnglat = pairs[0].split(","); GeoPoint point = new GeoPoint((int) (Double.parseDouble(lnglat[1]) *1E6),(int)(Double.parseDouble(lnglat[0]) * 1E6)); GeoPoint gp1; GeoPoint gp2 = point; for (int j = 1;j < pairs.length; j++){ lnglat = pairs[j].split(","); gp1 = gp2; gp2 = new GeoPoint((int) (Double.parseDouble(lnglat[1]) *1E6),(int) (Double.parseDouble(lnglat[0]) * 1E6));
