I need help looking, or possibly requesting an addon to be made if that works for you of course

hello, so you know how in half life 2, the combine soldiers and zombies have dedicated animations when they’re on fire? Well, I’m looking for an addon that gives that animation to every npc when they’re on fire, since right now when every other npc catches on fire, they stand still, take damage, and then just die. Any help is great please, thank you!
