The problems with my spaceship are:
1. despite not allowing for changing of targetPos when !moving, clicking while its moving to a different location will cause it to redirect the ship. Holding down the ship causes it to follow the mouse cursor.
once ship reaches the targetPosition, the rotation of the ship gets set to 0, im trying to make it retain the rotation of the angle just prior to it reaching its destination (e.g. distance to targetPos is 0).
When it reaches the boundaries sometimes it can go through it despite me adjusting the targetPosition if the mouse is too far into a deadzone the ship cannot enter.
