I discovered that trigger action Animation - Lock body part can be useful in some situations. But you can turn only head and torso. What is the requirement to allow unit to turn his part? Is the name of bones or something?
Thanks! Now I managed to make konstrukt_marine to turn his head by renaming helpers.
P.S. Maybe locking body parts can be useful for tanks which could attack while moving (with some triggering and JASS along, of course). What do you think? But this is maybe for other topic.
