I have a sprite of a robot character and I have an animation (of robotic hand movement) made from sprites (with the help of dope sheet view). I want to apply a collider on robotic hand in such way that it moves along with the arm. But I couldn't find anyway to change the collider with respect to each sprite frame? I tried Polygon Collider 2D but it remains same through out the sprite animation. Box Collider 2D don't rotate on each frame, it can only change its size and position. Does anyone know how to change the collider (rotate more specifically) on each frame of sprite animation ?
