I followed tutorial and read the manual about hotspot stuff, instead of use box collider or polygon collider is it possible to use the sprite itself ? This comes in handy if an animation of npc’s or object has an important space variation and avoid to draw the exact shape of a complex sprite to have pixel perfect detection.

You may, however, be able to have multiple colliders of different shapes attached and include changes to their enabled states (so that only one is enabled at a time) into the animation itself. That way, it can swap to a different one when the animation requires it.
