My Game Runs, But I Can't Move Around?

[AaronLLF]

Hi.

I'm developing a game (under a secret title ) and I need help with my code.

The code was originally a FPCamera from lloydgoodall.com, which came with SEVERAL errors, which I fixed. I also added a 3D cube and made a window for it.

I can run the game and the box shows up, BUT I can't move around. Here is my code:

import java.awt.event.KeyEvent;

    //the rotation around the Y axis of the camera
    private float       yaw         = 0.0f;
    //the rotation around the X axis of the camera
    private float       pitch       = 0.0f;
    //Constructor that takes the starting x, y, z location of the camera
    public FPCameraController(float x, float y, float z)
    {
        //instantiate position Vector3f to the x y z params.
        position = new Vector3f(x, y, z);
    }
    public FPCameraController() { // This is made so the line FPCameraController app = new FPCameraController(); will work
		// TODO Auto-generated constructor stub
	}
	//increment the camera's current yaw rotation
    public void yaw(float amount)
    {
        //increment the yaw by the amount param
        yaw += amount;
    }

    //increment the camera's current yaw rotation

    }

Sorry for the other replies, if anyone saw those, but figured it out properly...

In your "render()" method, you are calling "GL11.glLoadIdentity();" which basically erases everything that you set for the matrix in your "lookThrough()" method.  Comment that out.

Also, where you create the instance of "camera" and other "initialization" type variables, move that outside of the loop in the "run" method.

I have run this code, and it works perfectly for me:

There are still problems with your code though...

Your loop is really messed up and pushing "escape" doesn't work to close it.
You're using 2 instances of FPCameraController.  You only need one.  Just remove the 2nd instance and pass in "(0,0,0)" for the 1st instance in the "main(...)" method.
You can figure out the rest of these mistakes and any others.

Also, I suggest using static imports for portability, easy copy and paste for OpenGL C code, and not having to type GL11 everywhere.

Ummmm...

Any idea how to get the forward/backwards/mouse working? :/

[jediTofu]

The mouse works fine for me...like it moves it up, down, left, and right, not sure what you want it to do, but it does make it move.

[AaronLLF]

Yes, thanks, I re-input the code and it works. Though the mouse is reverse... I'll try to fix that.
