A question

I know I am stupid and can't code. If this post is deemed irrelevant or unintelligent, I'd prefer for things to still remain civil. This is the internet so that might not be possible. Oh well.

Is the area of the hitbox dictated by the server? If not, could it be made arbitrarily small?

Thanks.

Yes, it is controlled by the server. The hitbox is also slightly bigger then the player model too and projectiles can still hit you if they're about 1 centimeter off. It's stupid, but can't be helped.
