OnEntityTakeDamage

Alternatively, modify the HitInfo object to change the damage.
It should be okay to set the damage to 0, but if you don't return non-null, the player's client will receive a damage indicator (if entity is a BasePlayer).
HitInfo has all kinds of useful things in it, such as Weapon, damageProperties or damageTypes

Usage

• Return a non-null value to override default behavior
