Call of Duty 2 Play Animation

[Tally]

1) How many model I can add to the mod?
2) Can I control the bot player?

You can theoretically precache 1000 xmodels, but you will likely crash the server with the index-model overflow error before you get there, because maps have models in them to start with.

What type of animations are you trying to run? First-person ones? Or world animations?

For world animations, you can force an animation on a player or bot by putting the animation in a weapon file, and forcing the weapon on the player/bot. This is how Meatbot and Pezbot make the bots run, climb, throw a grenade, or shoot. This is very advanced stuff, and you are likely to need someone with experience to do it for you.

For first-person animations, you are pretty much stuck with having to create xanims and put them in a weapon file. Again, you force the weapon on a player/bot, and play the xanim.
