How to change and block unit Roll angle?

i want to know how i can block the unit roll angle. i have seen it done in Elimination, where the projectiles models could face a Z offset.. (a projectile angle "___" could be " \ "). i am actually making a map where you control a helicopter in 3D space , you can make loopings and all, but i would like the helicopter to have the same model Z inclinaison as my Helicopter_Inclinaison varriable, wich calculate the trajectory on a Z offset..
i am almost 100 % sure it doesnt exist in gui, so if anyone could give me the Jass function to change a unit inclinaison, i would be grateful.

24 hours and no replies? =(

I believe you can't do that, but you have to make the model have many different animations for each angle wanted.

I think elimination uses a dummy unit to do just that, and then attach the effect to the unit, but I could be wrong.

Yes, all maps with this use an imported dummy.
I've taken the liberty to attach it to this post for you.

(I forget which made it. >_>)

Use SetUnitAnimationByIndex(MyUnit, MyIndex) to set the pitch.
180 for the index is directly up, 0 is directly down.
Allows for full rotation.
Have fun.

Ooh, that's useful. What attachment points does it have?

Attachment point is "chest". And I'm nearly 100% sure it was Infrane.

The only problem with such a dummy model is that the actual model for the projectile/unit needs to be attached as a special effect, so it will only play it's stand animation (and birth/death when created/destroyed). Might be enough for a helicopter.

Thanks guys. it was exactly what i needed.

im actually editing the model to allow it to do a 360 degree turn.

Why not just add 180 to the facing angle instead?

Origin works too.
That's the one I use.
