Or the lack of a Keyboard.next() check, or both, FYI.

FYI, it was the lack of a Keyboard.next() check that was crashing it. How annoying.

The frame stops responding, but I'm not getting any command prompt messages. I always use the command prompt and a simple text editor, by the way. And you may add a instance.draw() inside the while (gameOn) loop (it doesn't really matter since it's never rendering it the second time around).

GL only. The latest hardware attempt was single-threaded. It still crashes. It's very weird because I've had a lot of success with the hardware renderer in the past, and I can't see anything wrong with this code. All ENTER is doing in this version is flipping gameOn.
Code: [Select]
private void draw() {
// buffer.clearZBufferOnly();
buffer.clear(Color.black);
xWing.rotateAxis(xWing.getXAxis(), rotationStored.x);
xWing.rotateAxis(xWing.getYAxis(), rotationStored.y);
xWing.rotateAxis(xWing.getZAxis(), rotationStored.z);
if (!cameraOnTie)
follow();
rotationStored.x = 0;
rotationStored.y = 0;
rotationStored.z = 0;
buffer.update();
theWorld.renderScene(buffer);
theWorld.draw(buffer);
drawAxisRep();
if (!openGL)
buffer.display(this.getGraphics());
else buffer.displayGLOnly();
}
public static void main(String[] args) {
boolean hardware = false;
if (args != null && args.length > 0) {
if (args[0].equalsIgnoreCase("OpenGL"))
hardware = true;
}
RogueSquadron instance = new RogueSquadron(hardware);
if (instance.openGL) {
instance.buffer = new FrameBuffer(800, 600, FrameBuffer.SAMPLINGMODE_HARDWARE_ONLY);
try {
Keyboard.create();
}
catch (Exception e) {System.out.println("Keyboard failed: "+e.getMessage());}
glLoop(instance);
Keyboard.destroy();
instance.buffer.disableRenderer(IRenderer.RENDERER_OPENGL);
instance.buffer.dispose();
}
}
private static void glLoop(RogueSquadron instance) {
int keyCode;
instance.buffer.enableRenderer(IRenderer.RENDERER_OPENGL);
instance.buffer.disableRenderer(IRenderer.RENDERER_SOFTWARE);
instance.draw();
while (!Display.isCloseRequested()) {
keyCode = Keyboard.getEventKey();
instance.keyPressed(keyCode);
if (instance.gameOn) {
instance.moveTowards(instance.xWing, instance.targetCone.getTransformedCenter(), .01f);
instance.follow();
if (instance.wingsHaveChanged)
instance.changeWings();
try {
Thread.sleep(50);
}
catch (InterruptedException e) {}
}
}
instance.gameOn = false;
}

The main thread (in static method main(String[]) calls draw() once, after which time all it does is check the keyboard. When you press ENTER a new thread, the game loop, starts. But in OpenGL mode, all I'm getting is a frozen window. I have to have Windows kill the process.

Thanks a lot, that was simple!
Another question: I'm getting crashes with a second thread in hardware OpenGL mode. It doesn't happen in software mode. Is there anything about OpenGL or otherwise lwjgl that can't be multi-threaded?

How do I make it so that a ship is rotated around its own axis? As I understand it, objects are rotated by the world axis, so that the moment I rotate a ship in any of its 3 axis, it's no longer aligned with the worls axis. Or am I far off here?

The hero doesn't rotate at all. And he sometimes rotates awkwardly.

I need the hero to look in the direction of the mouse click. By the way, I could just use the original mouse coordinates which are already in 2D. So shouldn't converting the hero's center and the hero's direction vector (in front of him) to 2D and then calculate that angle make sense? And if you agree, tell me if my changes work and if not please make your own. Thanks a lot.

OK, now I'm confused. My s1 was the hero's transformed center, and my s2 was the mouse click's position.
The hero''s transformed center is the origin. I have a direction vector for the keyboard that's always directly ahead of the hero, and I have the direction vector of the mouse click. What exactly should I feed into the method and for that matter, what version of the method? Yours?

OK, but I still think that a Math class with all sorts of operations would be invaluable.
By the way, you know my problem and it didn't work for that one. I also tried the 2D variation that follows. Why doesn't it work?

public float calculateAngle(SimpleVector s1, SimpleVector s2) {

Point p1 = new Point((int)p13d.x, (int)p13d.y);
SimpleVector p23d = Interact2D.project3D2D(theCamera, buffer, s2);
Point p2 = new Point((int)p23d.x, (int)p23d.y);
float pa=(float)p1.x*(float)p2.x+(float)p1.y*(float)p2.y;
// Inaccuracies may cause NaN...fix this:
if (pa<-1)

return (float) Math.acos(pa);

Thanks a lot. What about my suggestion of adding a Math class? Could be quite useful and wouldn't make jPCT cumbersome in any way.

More specifically, I'm trying to calculate a 2D angle, so this method would only use the x and y components of the SimpleVector class. static float calculateAngle2D(SimpleVector origin, SimpleVector p1, SimpleVector p2) might be a better name!
