immune

int [] Terraria.NPC.immune = new int[256]

This determines if an NPC can be hit by a item or projectile owned by a particular player (it is an array, each slot corresponds to different players (whoAmI)). It is decremented towards 0 every update. Melee items set immune[Player.whoAmI] to Player.itemAnimation, which starts at item.useAnimation and decrements towards 0. Penetrating projectiles usually set immune to 10, while non-penetrating projectiles do not set immune. ExamplePiercingProjectile.csexplains more about options for npc and projectile immunity.
