I’ve got my character doing a spinning kick animation. How do I make the kick damage enemies in a circle around my character? Thanks.

What you can do is use Physics.SphereCastAll

That will basically check all that was hit within a sphere then return an array of RaycastHits which you can then use to access the colliders/objects that were hit in order to do things like apply damage and so on.

Physics.SphereCast for 3D, Physics2D.CircleCast for 2D.
