I added the perspective camera like this:
camera = new PerspectiveCamera(67, VIRTUAL_WIDTH, VIRTUAL_HEIGHT);
gluPerspective is the same, right?
OK. I try to explain. e.g.
The sprite is moving from left to right. When I now
System.out.println(sprite.x+" | "+sprite.y)
I get this e.g. x:50, y:100 or x:55, y100 or x:500, y:100 etc.
The (0,0) is left bottom!
Now I don't know how move the 3d object at this positions? This is not working:
Gdx.gl10.glTranslatef(sprite.x, srite.y, -35.0f);
For e.g. When I do this,
Gdx.gl10.glTranslatef(100f, 0.0f, -35.0f);
I don't see the 3d object on the screen:
