Add an asset property/properties similar to BladeID for entities to take damage if it and the damage source match the property ID. This makes it so that entities take damage by specific means, which exists in Unturned, although limited to trees and certain melee weapons.
The property must have at least one ID and can accept multiple more if desired. It must also be usable for weapons, throwables, vehicles, barricades, structures, and everything that deals and/or takes damage in the game.
It can be a good tool, such as making vehicles susceptible to damage by some guns and launchers or making throwables that can blow up a specific player structure or barricade. Creatively, it may also used on some clothing items so that a player can start taking damage with the appropriate item or damage source that has the same property ID.
