Re: How do I show hitboxes during play?
If in the Unity Editor you can just select to see HitBoxesScript.cs' gizmos in either the Scene or Game view.
In-game though out of the Unity Editor, there is no out of the box way to visualize in game. You'll have to code some script to spawn an object/primitive at each hitbox's location with the known parameters and assign a material to render it properly.
