[Trigger] turning a unit except...

[doom_sheep]

...i want it to turn up and down rather than left and right. is it doable? beastmaster's roar in dota seems to use roar effects that are turned sideways.

 

[morbent]

I don't think it's possible... and the beastmaster roar aint turned sideways... I think.

You can fiddle around with the unit's pitch angle and roll angle in the object editor (http://puu.sh/EOGW)
If you imagine someone doing front flips or back flips, the pitch turns the unit in the same way. On the other hand, the roll will make the unit turn similarly to cartwheels.

You need to set them to negative values to see any effect. Hold shift and click the pitch/roll entries to be able to set them to negative values.

Here is an upside down footman: http://puu.sh/EOGr

The world editor does not provide a way to do this with triggers. However, if you know vJASS, the XE spell library brings support to turn special effects along the z axis like you want (http://www.wc3c.net/showthread.php?t=101150). It does not help much if you actually want the unit to be controllable though.

actually all i want is a projectile that turns to face up/down during it's arc.

can it be done with a custom script?

Yes, that is actually precisely the sort of thing the XE spell library is useful for. In particular the xemissile library is intended to be used for projectiles that travel through the air similarly to wc3's unit missile attacks.

You can, of course, simply take the xe dummy unit's model and roll out your own solution if you feel like it. The dummy unit's model has around 180 animations to it, each one corresponding to a z angle. You would have to attach your missile's model as a special effect to the dummy model and set the dummy model's animation to the appropriate number to do the rotation.

I recommend simply using xemissile though.

The hive has a resource for missiles as well that seems to control arcing using the same model, viewable here: http://www.hiveworkshop.com/forums/jass-resources-412/system-missile-207854/
Have not tried it myself, though.

i'm not going to import an entire system in a language i can't read for one spell.

i think i'll just replace the missile mid-air or something.

So you want a realistic-looking projectile system ?
Which the tip of the projectile will obey the rules of Projectile Motion ?

Well, if you are comparing to Rexxar's ultimate, Primal Roar, it uses a static dummy unit, therefore it can be achieved by just editing this;
Art - Maximum Pitch Angle (degrees): -90 (face down) / -270 (face up)

That's how Rexxar achieve the effect.

kind of got told that already. thanks anyway.

did it by replacing the unit a couple times. you can consider this solved.

Haha unefficient as it seems.
