Half Life 2 Animation Fix

[08/27/2023] YOOO! Made it to the most popular addons page! Thanks everybody!

[08/08/2024] As of the July 2024 Update, Facepunch has finally fixed the Alyx, Kleiner, and Vortigaunt animations. HOWEVER, they have yet to fix other models such as Eli and Dog. Therefore, you will still need this addon if you want to play through all of the campaigns.

I will be updating and removing changes as Facepunch makes their own fixes. Ultimately, once all of the models have been fixed, I will revert the changes on this addon prior to the July 2024 update for posterity's sake and for those who wish to play on an older version of Gmod.

[08/11/2024] Alright, I have decided to revert the addon back to its release prior to the July 2024 update and will keep it as is. As of this writing, Facepunch has yet to fix all of the models. If you would like to keep track of their progress, please look at Gmod Issue #5945[github.com]. (Yes, I am the one who posted that issue).

HEY! To ensure this addon is working properly, restart your game after downloading and installing it!

ALSO! If you would like to make a model replacement or just plain curious as to how this mod works, check out my guide about the animation fix HERE!

Have you ever wanted to play the Half Life 2 campaigns on Garry's Mod, only to find out that Episode 1 and Episode 2 failed to work because of broken/missing animations? Well look no further! This addon addresses this problem by having the Half Life 2 models gain access to their animations from all three games!

FEATURES:

• Half Life 2, as well as it's subsequent Episodes, are completely playable WITHOUT restarting gmod!
  
• Alyx can now convert rollermines to your side! (Even her injured Episode 2 counterpart!)
  
• Alyx can now enter and ride with the player in the Jalopy! NOTE: if you want to do this outside of the Episode 2 campaigns, you will need an additional mod to do so, such as Enhanced Sandbox NPCs by Blixibon
  
• Dog can use his Episode 1 inspect/throw animation when he plays fetch with you! NOTE: this can make the box catching sequence in Black Mesa East a bit buggy; you can "force" your way through this sequence by walking up and destroying the box in Dog's hand with the Gravity Gun
  
• Vortigaunt animations are set to their Episode 2 counterparts, so they move and attack faster!
  
• Vortigaunts can now utilize their aoe attacks!
  
• Combine Turrets now have access to their Episode 2 skins!
  
• Combine Mines (Hoppers) now have access to their Episode 2 skins!

BUGS:

• No Alyx/Vortigaunt finishers; this is a technical issue, not an animation issue. *Fixed in the July 2024 Update, but ONLY if the console command hl2_episodic is set to 1 or 2*
  
• Half Life 2/Episode 1: The Advisor in the monitor is angled a bit off from the camera since it now uses the Episode 2 models.
  
• Episode 1 Intro: Vortigaunts have no blue texture *Fixed in the July 2024 Update*
  
• Episode 1 Train Sequence: Alyx is a bit misaligned from the stalker she's pinned against (just a visual bug; you can play through the sequence without any problems)
  
• Episode 2 Gman Sequence: The camera will initially zoom backwards and through the map, but will fix itself in subsequent cuts.
  
• Episode 2 White Forest Strider Defense: Two Alyxes will spawn if you transition from the previous level (this is a problem caused by Gmod). To fix this, immediately delete the Alyx that spawns with you. *Fixed in the July 2024 Update*

FAQ (I will update this as needed):
Q: Do I need Half Life 2/Episode 1/Episode 2?
A: This addon only contains .mdl files, so YES you DO NEED the respective games to be properly loaded onto Garry's Mod if you want to access the maps, prop models, etc.

Q: Can you fix the Episode 1 intro so that the vortigaunts are glowing blue?
A: Yes and no. I do actually have a fix for this problem (and it works!), but unfortunately it causes the vortigaunts that heal Alyx in Epsiode 2 to go invisible, since they use the same model. As far as I'm concerned, it looks like a material issue, which is something beyond my capabilities. *This is fixed in the July 2024 Update*

Q: Can we use custom models and still have animations work?
A: YES! See the guide posted at the top of the description on how to make model replacements compatible for all three Half Life 2 campaigns!

Q: My model replacement isn't working! What gives?
A: Is your model replacement loaded AFTER this addon? If not, then the game will end up using the default models that come with the animation fix. For more details, check out the guide I posted at the top of the description.
