How to make mouse navigation?

Question

I am using LibGDX for my game and I want the mouse to move the "head" of the player, eg. like in Minecraft. How would I achieve this? I have got it to kinda work with yaw and pitch values that glRotateF what is being rendered, but the mouse moves outside the window (obviously) after a while of turning right. I have tried to use the robot class to reset the pointer position to the center of the screen but then navigation is nearly impossible.

Here is my player class:

package com.amzoft.gdxracingtestgamething;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.InputProcessor;
import com.badlogic.gdx.graphics.GL11;
public class Player implements InputProcessor{
 int pitch = 0;
 int yaw = 0;
 public Player()
 {
 }
 public void render()
 {
 GL11 gl = Gdx.gl11;
 gl.glRotatef(-yaw, 0, 1, 0);
 gl.glRotatef(-pitch, 1, 0, 0);
 }
 /*....a ton of unused implemented methods*/
 int xBefore = 0;
 int yBefore = 0;
 @Override
 public boolean touchMoved(int x, int y) 
 {
 if(xBefore<x-3)
 {
 yaw += 1;
 }
 if(xBefore>x+3)
 {
 yaw -= 1;
 }
 if(yBefore<y-3)
 {
 pitch -= 1;
 }
 if(yBefore>y+3)
 {
 pitch += 1;
 }
 if(yaw > 90)yaw = 90;
 if(yaw < -90)yaw = -90;
 if(pitch > 90)pitch = 90;
 if(pitch < -90)pitch = -90;
 xBefore = x;
 yBefore = y;
 return true;
 }
 @Override
 public boolean scrolled(int amount) 
 {
 return false;
 }
}

Im sorry if the solution is very obvious, I am very new to 3D game development and LibGDX.

• Displayname1234: anyone know how to accomplish this?? I know it probably involves trigonometry which I dont understand (yet)...

Answer 1

Trigonometry :) I used gluLookAt to make the camera look at the coordinates that were calculated from the sine, cosine and negative cosine of the yaw and pitch. It works pretty well.
