Forcing the hammer to hit when swung at players

Basically wondering if you can change the behavior of the building hammer so that it will register hits on players. Ideally, I'd like to change the behavior so if an animal is hit, it does nothing.

I haven't found any examples of this existing either.

 

You can get what the player is looking at when they swing the hammer, but you can't make the hammer make physical contact with something it doesn't normally to my knowledge.
