the update_camera_pos() func is working fine,
But another problem:
what values should i put in world_layer.transform_anchor?
I tried putting the sprite's position, and when zooming, it correctly
anchored to the center of the sprite.
However if I moved the sprite (and update_camera_pos()), the sprite
becomes farther from center of the window if I move the camera from
the center of the game world.
Thanks
