 }
 

I have a script set up so a NPC (That is spawned in with another script when the game is a server) walks on a set path around a town. However Animation.crossfade doesn't work, and niether does animation.Play.

I debugged it a bit and I know the PlayAnim is being played I've moved where its being called a bit and it doesn't work, and I know that the script is trying to run the correct anim so I'm not sure what to do.

Thanks in advance for help.
