Java Game APIs & Engines / OpenGL Development / Re: Implementing an FPS Camera [solved, thanks irc :D]

on: 2012-10-21 16:50:17

I solved it

The key was that i got my game loop like:

1
2
3
4

while (running) {
     clear(); // clear the view and such, move the camera
     render();
}

And the Display.sync method was inside the render() method, so clear() was working in a different fps than the rendering.

Thanks all !!

thanks for replying What i mean is that it works bad. So if I press "W" to go forward, it does 1 "step" and then stops, after a few seconds, does another one, and such, while what it has to do is walk forward. If u download the source and run it you will see what I mean. It don't works smoothly

I'm trying to implement Lloyd's FPS camera in my coude but it works very bad, dont know why. I've tried to put the functions that moves the camera into a while (Keyboard.next()) loop but works worst when I do it... I realy dont know what to do here :S. The game isn't laggy, works at 60fps here is the source code: http://www.mediafire.com/?da5z2akca1jnnda the "important" classes are: Game.java and FPCameraController. There's actually a "InitGL" method into Screen class and I dont know if has the appropiate settings for this setup. Well, I hope somebody can help me Thanks!

Java Game APIs & Engines / OpenGL Development / Having problems to understand OpenGL view method... [solved]

Hello!

I'm trying to make a 3D game with LWJGL and right now I got the movement basics in 2D (moving a cube upwards when pressing "W" and such...) but now I want to move the camera so I get a nice 3D view. I'm trying to do it with gluLookAt() but it just don't have any result at all... I've drew the cube at 0,0,0 and I wanted to go a bit far so I can see it completely but gluLookAt does nothing. I don't actually know exactly after what MatrixMode I have to write it, MODELVIEW or PROJECTION? >.<

I'm using this:

1
2
3

GLU.gluLookAt(0.0f, 0.0f, -5.0f,
                 0.0f, 0.0f, 0.0f,
                 0.0f, 1.0f, 0.0f);

I've tried using it after

1
2
3

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glLoadIdentity();
glMatrixMode(GL_PROJECTION);

and after

1
2
3

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glLoadIdentity();
glMatrixMode(GL_MODELVIEW);

but no one works. I've actually tried using gluPerspective but I need to change the view's angle so...

I've also tried to use glRotatef(30.0f, 1.0f, 0.0f, 0.0f) and glTranslatef(0.0f, 0.0f, 5.0f) but had 0 effect xD

I need a bit of help here! Help please

edit: So i searched thru google (i did that before "-.-) and finally find a piece of code that worked well for me:

1
2
3
4
5
6
7
8

glMatrixMode(GL_MODELVIEW);
       glLoadIdentity();
       GLU.gluLookAt(0, 1, 5, 
                     0, 0, 0, 
                     0, 1, 0);

       glPushMatrix();
       glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

And after that put all the cube's code.

wow x) thanks for the replies I got some mindf**ks trying to port JOGL 1 to JOGL2 so porting LWJGL to JOGL2 .______. ... I'll give it a try but, someone has JOGL2 ones?

Hi! I'm starting with JOGL and I've seen multiple tutorials about geometry and thouse with JOGL and now I need some tutorial or guide about the creation of a complete (simple) game. I've search it but I can't find it so... someone knows about some webpage with tutorials like that or some ebooks? Thanks!
