Get angle of Sprite(Tween Property)- Can be done by storing the angle of an object in a variable("Angle Variable") by using the Sprite.Angle expression
2)Set Angle of Sprite- Can be done by passing the "Angle Variable" in the set angle action.
I actually made a little plugin for this that can save/restore width, height, x, y, angle and opacity of objects... I just never put it out there. Maybe I should :V
