Why we used rb.addrelativeforce instead of rb.addforce ? what will be the difference
AddRelativeForce
adds force relative to the object’s coordinate system. That is it’s local space. AddForce
adds force in world space. If you AddForce
in the Vector3.up
direction, it will be ‘up’ relative to everything, i.e. the top of the screen. AddRelativeForce
in the Vector3.up
direction is towards the rocket’s top, no matter how it is rotated. We want the rocket to go towards its top, not the screen’s top.
