feat: add movement behaviors

Browse Source 
the following behaviors will function
MoveRight
MoveLeft
FlyUp
FlyDown
MoveForward
MoveBackward

The behavior of the behaviors is once a move in an axis is active, that behavior must finish its movement before another one on that axis can do another movement on it.
