Hi,

I add a perspective camera.

1  
    cam = new PerspectiveCamera(45, 480, 320);


When I try to get the touchpoints with

1  
    (Gdx.input.getX(), Gdx.input.getY())


I get wrong numbers. My Perspective width is 480.

When I touch with my finger the screen (rightmost), I get 1196.

This is my screen resolution of my device.

EDIT: I also get wrong numbers when I try:
 
1  
2  
3  
4  
5  
      private Vector3 touchPoint;

       cam.unproject(touchPoint.set(Gdx.input.getX(), Gdx.input.getY(), 0));

       System.out.println(touchPoint.x+" | "+touchPoint.y);

    I get something like this with touchpoint.x: -6 to 0.75

Hi,

I solved it now so:
1  
2  
3  
float X = MathUtils.round(Gdx.input.getX()*(480f/1196f));

float Y = MathUtils.round(Gdx.input.getY()*(320f/720f));


If there is a better solution, then please post it.
