Sabre-aN's Headcrab Zombie Mod

In short, what this mod does is:
-Adds 25 new Headcrab Zombie variants.
-Adds new Headcrab Zombie playermodels.
-Adds a 'Skin Randomiser' feature that will randomly change the skin of the zombies spawned naturally by the map, and the ones from the NPC spawnmenu that have a '?' on their icon. The skins used can be configured from a menu in your utilities menu.

Want the Rebel Zombies for your Half-Life 2 games? There's now a small model replacement addon for that, get it here: http://www.moddb.com/games/half-life-2/addons/sabreans-hl2-headcrab-zombie-improvements

!THIS MOD REQUIRES HALF LIFE 2: EPISODE 1 MOUNTED IN GARRY'S MOD FOR THE ZOMBINE NPCS TO WORK FULLY! With only Episode 2 mounted (not Episode 1) they will appear in the spawnmenu but may have no sounds. Without Episode 1 or 2, they will not appear in the spawnmenu at all. The rest of the NPCs work fine without any of the Episodes

--------------------------------------------------

IF ALL ZOMBIES ARE THEIR DEFAULT HL2 VERSIONS then you have some form of model conflict. So far this has been found to be caused by any of the following:

1. Conflicting Workshop Addons - To solve, look through all your other addons' contents via Gmod's ingame prop browser. If any contain the HL2 zombie models, disable them and restart. If you want to quickly check if it is an addon before starting this, simply disable all other addons and test.

2. Zombie models in the main garrysmod directory - Go to your "C:\Program Files (x86)\Steam\SteamApps\common\GarrysMod\garrysmod" folder. If there is a "models" folder, open it. If there is then a "zombie" folder inside, delete it. If there is no zombie folder then this was not the cause.

3. Content Packs - This should be obvious, pirated content packs for HL2 games will contain all a game's content, including the HL2 zombie models, and so will cause a model conflict. So if you have ever had any of these, delete them. Pirating's bad, mkay?

4. Mounting Issues - After the November 2017 Gmod update, some people have suddenly reported this issue starting for them. This was solved by one person via the following procedure:

--1.Launch Gmod if necessary, go to the main menu
--2.Unsubscribe from this mod
--3.Make sure all games are unmounted via the mounted games list - make sure every box is unticked.
--4.Close Gmod
--5.Go to your garrysmod/addons folder and delete this mod's .gma file if present
--6.Resubscribe to this mod
--7.Launch Gmod, remount the appropriate games via the mounted games list
--8.Restart Gmod, launch a map and test.

--------------------------------------------------

This addon changes adds zombified versions of all the main groups from HL2 that were missing - citizens, blue and green rebels, blue and grey medics, metrocops, combine shotgunners, combine prison guards, and combine elites, while keeping the original versions.

You can use the 'Skin Randomiser' to configure what zombie variants will spawn. Just go into your 'Q' menu, then go to the utilities tab on the right, and then go to 'Skin Randomiser' under 'Headcrab Zombie Mod'. There you will find checkboxes for all the variables - if you check a box, it enables the corresponding feature.

The way this mod works is that this mod replaces your stock zombie models with new versions that have been compiled with extra models effectively 'built in', which are normally set to use an invisible texture until a skin which needs the extra model part is selected - this can be seen on skins like the Rebel Zombie skin, where he gains his combat vest, backpack, and bits of armour etc. or the Zombine Elite, who gains his correct boots. This means that if you have any other addons which replace the standard zombie models, you will need to disable them in order for this mod to function.


KNOWN BUGS:

-When having the 'Random Zombies can be Zombine' checkbox enabled, zombies produced from spawners, either naturally in the map or forced, are 'forgotten', leading to a new replacement zombie being spawned regardless of whether the maximum amount of NPCs it was supposed to spawn has been reached. Normally this isn't a problem but if settings are set such that all zombies are turned into zombine, this can result in infinite zombine in some cases.

-When Joining a server that doesn't have this mod installed, zombies will use bizarre animations
This is because the animations I've used do not exactly match up with those used stock by the source engine. It is possible to fix this bug, I actually had it sorted for a while, but it comes at the price of the models being unstable and disappearing when viewed from certain angles (due to not having a base $sequence in their .qc file, if you must know, as the only way I can get the animations to match up is via $includemodel) This is not a price I am willing to pay - the solution is to simply disable this addon when trying to join a server that does not have this mod
