Half-Life 1 like Helmet and Armor Hitbox on NPCs

To make this mod work, you have to copy the vpk file located in steamapps\workshop\content\362890\2566368072, and paste them in the custom folder (create one inside the bms folder if you dont have one). I do not know why the mod does not automatically work.

This mod adds a protective hitbox on all NPCs that wears helmets. That includes the marines, alien grunts, and black mesa guards. Shooting these NPCs in their helmets with any weapon (except the crowbar and the gluon gun) will inflict no damage just like in the original. I also removed the headshot hitbox on alien grunts so they can last even longer in combat (instead of being cheaply killed by a 357 shot. This mod also adjusted the armor hitboxes on alien grunts. Additionally, I slightly changed the marine shotgunner's model so instead of just being a generic gasmask dudes, they now always wear sunglasses without helmets and gasmasks (i made them look like their HL1 shotgunners minus the balaclavas). These guys also have a damage reducing vests (although this doesnt nullify all damage, they just reduce it for balancing reasons). To modify how much damage is reduced, you can edit this cvar "sk_npc_ricochet". The default value is 0.8.

This mod uses character_manifest.txt and global_actors.txt and they are absolutely essential to make this mod work as intended. If you want to incorporate the changes i made in these files to your other mods, you can copy the changes that i made. I changed the following npcs along with their SCRIPTED appearances (do not forget them):
For the character manifest:
npc_human_commander
npc_human_grunt (also with "Specific grunts")
npc_human_grenadiers
npc_human_medic
npc_human_security (also with "security_no_armor", "specific guards" amd "specific (name of the chapter appearance")
For the global actors:
Added a new model for commanders named commander_marine and commander_marine_02
All shotgunners (marked by their _sg suffix) are now classified as male (the male and female thing here refers to their normal voice or "gasmask" voice. Apparently the female voice is the gasmask voice.)
