moveTowardsTarget<T extends GameComponent> method

bool moveTowardsTarget<T extends GameComponent>({ required T target, Function? close, double margin = 4, MovementAxis movementAxis = MovementAxis.all, })

This method move this component to target Need use Movement mixin. Method that bo used in update method. return true if moved.
