Also, make sure your browser has an up-to-date JRE plug-in installed. The latest is 6 (or 1.6) but that's a prerelease, so 5 (update 9) should be fine ----------------------------------- gsquare567 Tue Dec 05, 2006 3:49 pm ----------------------------------- i based my entire game on the LinkedList which is where i store the sprites or objects on the screen... so i'll try downloading the latest plugin and update, i'll get back to you to tell you if it still doesnt work. ----------------------------------- gsquare567 Tue Dec 05, 2006 4:03 pm ----------------------------------- nope, didnt work. still says "Applet GalacticWar notinited". i dled the jdk 5 update 10... ----------------------------------- gsquare567 Wed Dec 06, 2006 7:16 pm ----------------------------------- BUMP... and, added a lil info if it helps you solve this complex error :D. ok. i re-dled the whole jse and got update 10. heres the shiz lol: HTML CODE Galactic War - enhanced by Gsquare567 FIRST LINES OF MAIN JAVA CODE public class GalacticWar extends Game abstract class Game extends Applet implements Runnable, KeyListener MANIFEST FILE CODE Main-Class: GalacticWar PS thanks a lot for helping me man. if you actually solve this problem... well... iunno i'll thank you. :?

----------------------------------- gsquare567 Wed Dec 13, 2006 9:57 pm ----------------------------------- ok, this is REALLY buggin me, so im just taking random guesses, hoping someone can help. so it says applet notinited, i thought, well maybe its the init method. well, here it is, i checked EVERYTHING i could, but there is something missing/incorrect. help! please! public void init() { backBuffer = new BufferedImage(screenWidth, screenHeight, BufferedImage.TYPE_INT_RGB); g2d = backBuffer.createGraphics(); sprites = new LinkedList(); addKeyListener(this); gameStartup();// implemented by subclass } and here is the method implemented by the subclass. void gameStartup() { // load sounds and music music.load("music.midi"); shoot.load("shoot.au"); explosion.load("explode.au"); // load the health/shield bars barFrame = new ImageEntity(this); barFrame.load("barframe.png"); barImage[0] = new ImageEntity(this); barImage[0].load("bar_health.png"); barImage[1] = new ImageEntity(this); barImage[1].load("bar_shield.png"); // load powerups powerupShield = new ImageEntity(this); powerupShield.load("powerup_shield2.png"); powerupHealth = new ImageEntity(this); powerupHealth.load("powerup_cola.png"); powerup250 = new ImageEntity(this); powerup250.load("powerup_250.png"); powerup500 = new ImageEntity(this); powerup500.load("powerup_500.png"); powerup1000 = new ImageEntity(this); powerup1000.load("powerup_1000.png"); powerupGun = new ImageEntity(this); powerupGun.load("powerup_gun.png"); // load the background background = new ImageEntity(this); background.load("bluespace.png"); // create the ship shipImage[0] = new ImageEntity(this); shipImage[0].load("spaceship.png"); shipImage[1] = new ImageEntity(this); shipImage[1].load("ship_thrust.png"); shipImage[2] = new ImageEntity(this); shipImage[2].load("ship_shield.png"); AnimatedSprite ship = new AnimatedSprite(this, getGraphics()); ship.setSpriteType(SPRITE_SHIP); ship.setImage(shipImage[0].getImage()); ship.setFrameWidth(ship.getImageWidth()); ship.setFrameHeight(ship.getImageHeight()); ship.setPosition(new Point2D(SCREENWIDTH/2, SCREENWIDTH/2)); ship.setAlive(true); ship.setState(STATE_EXPLODING); collisionTimer = System.currentTimeMillis(); addToSprites(ship); // load the bullet bulletImage = new ImageEntity(this); bulletImage.load("plasmashot.png"); // load the explosion explosions[0] = new ImageEntity(this); explosions[0].load("explosion.png"); explosions[1] = new ImageEntity(this); explosions[1].load("explosion2.png"); // load the asteroids for(int i = 0; i < 5; i++) { bigAsteroids[i] = new ImageEntity(this); bigAsteroids[i].load("asteroid" + (i+1) + ".png"); } for(int i = 0; i < 2; i++) { medAsteroids[i] = new ImageEntity(this); medAsteroids[i].load("medium" + (i+1) + ".png"); } for(int i = 0; i < 3; i++) { smlAsteroids[i] = new ImageEntity(this); smlAsteroids[i].load("small" + (i+1) + ".png"); } for(int i = 0; i < 4; i++) { tnyAsteroids[i] = new ImageEntity(this); tnyAsteroids[i].load("tiny" + (i+1) + ".png"); } // start in pause mode pauseGame(); } i checked that all files were written correctly, although i wasnt sure if a MIDI file's extension was mid or midi so i tried both, and neither worked, so i assume it doesnt matter. also, the au extension is for an AU file, and png is for PNG... so i know those are correct. what could be the problem? just throw things PLEASE! ----------------------------------- Neville Wed Dec 13, 2006 11:40 pm ----------------------------------- I would start by debugging as much as you can. Do you use an IDE with built in debugging? This way you could step through and see where it is failing. If not, try writing an output file with little messages to see how far along your init() goes before it fails. That way you can narrow down the problem. It's most likely an exception being thrown somewhere.
