How to make zombies immune to ranged attacks and only vulnerable to melee damage?

[adrian]

I am trying to make a zombie that can only be damaged by melee attacks. Is it possible?

As a mod / buff, yes.

If you greatly decrease the entityDamage passive, tagged for ranged and explosives then those damage types will do at most 1 point of damage.

I tried copying the wrestler effect buff from Snufkin's mod which reduces entity damage and increases melee damage but I can't get it to work. 

Can I see a sample code on how to implement it? Thanks!
