how easy is it to animate NPC's? I can't find any tutorials on how to do this. I'd want to learn something new, and adding a couple friendly NPC's sitting or walking would be nice.
It's just a matter of spawnscript or usescript. Look for the SET_ANIM_UPPER, SET_ANIM_LOWER and SET_ANIM_BOTH commands in BehavEd. Also experiment with SET_ANIM_HOLDTIME_UPPER, SET_ANIM_HOLDTIME_LOWER and SET_ANIM_HOLDTIME_BOTH with a number of milliseconds to hold their animation still.
