Hi. I have a ball that moves arround with wasd and a camera that follows the ball in a third person perspective. I can move the camera around using the mouse. How can apply a force to the ball to where the camera is pointing to ?

Cast a ray from the camera’s center, get it’s normal. Use the normal to multiply by some speed value.
