PlayObjectAnimation ('creature_name', 'anim_name', anim_type)

Instead of creature_name, you need to specify the name given to the creature on the map.
Instead of anim_name, you need to specify the animation that the creature should have. Examples: attack00, specability, rangeattack.
Instead of anim_type, specify an additional animation type: ONESHOT – plays once until the end, ONESHOT_STILL – plays once and freezes at the end, IDLE – plays infinitely until the end, returning to the initial position and replaying the animation over and over.
