  java rotation collision slick2d
  I have started to develop a basic game in java. The view is top down, the player is represented by a green circle, and the enemies by red circles. The player has a sword. If an enemy touches the player, it gets hurt. If the sword touches an enemy, it is killed.The basic collision detection of the player<->enemies and enemies<->sword work (i use bounding ellipses). But i cannot rotate the ellipse representing the sword around the player. It stays at one place. I have tried with Transform.cr

  I’m using slick2d and in my Java application. In my render method I use a method called changeBackground();@Override public void render(GameContainer gc, StateBasedGame sbg, Graphics g)throws SlickException { changeBackground(g); }changeBackground();public void changeBackground(Graphics g) throws SlickException{Thread.sleep(500);g.setBackground(new org.newdawn.slick.Color(0, 255, 0);Thread.Sleep(500);g.setBackground(new org.newdawn.slick.Color(255, 0, 0);changeBackground(g); }When I run my appli

What is the difference betweenImage spriteImage = new Image(“content/man.png”);andspriteImage = new Image(“content/man.png”);(Which actually works)

  When I debug the game in eclipse the game works fine. However, when I make runnable jar out of it the game crashes when enemy gets hit, the rest of the game works fine except that part. What do I do, how do I debug runnable jar?

  java animation slick2d
  I’m working on a game with some basic graphics that utilizes Slick2D. In order to display an animation I have to display an image that’s both rotated and scaled, so I quickly discovered that none of the methods in the Animation class would work for me.The solution I came up with was to draw the image at Animation.getFrame() (the animation’s current image). To update the image I call the following lines of code:System.out.println(“Updating animation data…”); a.setAutoUpdate(false);a.update(delt

  Whenever I use the method getGraphics() from org.newdawn.slick.Image in fullscreen mode, it causes a crash. It works perfectly fine in windowed mode, and I’ve tried doing stuff like Graphics g = new Image(100,100).getGraphics(), this also causes the crash.I am using Slick2DThis is the output I get: Tue May 07 14:58:08 CEST 2013 INFO:Slick Build #264 Tue May 07 14:58:09 CEST 2013 INFO:LWJGL Version: 2.9.0 Tue May 07 14:58:09 CEST 2013 INFO:OriginalDisplayMode: 1366 x 768 x 32 @59Hz Tue May 07 14:

  java lwjgl slick2d slick
  I have recently been programming a platforming game in java, and I have run into a problem when I tried to use a separate class to store my map (tiled). I then tried to fix it by moving the map into the main class, and it didn’t help.This is the code that is causing the problem (When the world.map1.render(0,0) is removed, no problem exists) – I know that I should be using getters and setters. I’m just find them a pain.public void render(GameContainer arg0, Graphics arg1) throws SlickException {
