?ちょっと意味がよくわからない
Create collider - Ticking this will automatically create and animate a box collider.
You should tick this if any of the animation clips you play for this sprite will need a collider.
For example, if you start at a default idle animation which doesn't need colliders,
and you could potentially play an attack animation which needs a collider,
you should tick this here so no dynamic allocations will be performed.
