You could use Hitbox:GetTouchingParts() (say, every time you swing your fists). It’s more accurate than .Touched. However, raycasting is more accurate and is apparently less resource intensive. There’s a module you can find here:
You can easily use fists with this module (people have done it already) and it supports all types of hitboxes. If you’re looking for something simple, that’s the way to go. But if you’re advanced and want to create your own raycasting system, that module is a good place to start.
