Try to make a space game, the ship is always on the center of the screen.
With A and D key i can torque the ship. This works so far.
But with W-key i want to accelerate the ship with torque direction (and other physic behaviors).
So the ship should not move, all other things must move (background stars, other objects, etc.).
How can this be done?
The examples and so on i found, are always for a moving player.
