Possible to disable turning

[MathsDebator]

As title suggests: is it possible to disable a unit from turning? It would be an interesting skill for a future hero..

[MauranKilom]

You can pause/stun him... Effectively prevents him from turning...
But i guess that's not what you were looking for.

Setting turnrate to 0 will make any turning instant (as opposed to making it impossible). it slow, but not impossible.

You can simply turn the unit back to its original facing angle every 0.1 seconds, as is done with Black Hole.

But will the unit be able to move by spam-clicking the move command?

[EebstertheGreat]

Yeah, he could move slightly diagonally, not just straight forward. However, if you reduce the interval to 0.01 seconds, this effect would be completely negligible. You can't turn very much in a hundredth of a second.

Setting turnrate to 0 will give a unit the lowest possible turnrate. If you want to make a unit only to be able to move forward for some seconds this could be a good solution.

that's just in the object editor which uses a different way of showing turn rate and has a minimum of 0.10, whatever that means. in practice the unit turns slow but very clearly is still able to turn.

Oh man, messed that up with 0 movespeed... Sorry.

[MathsDebator]

okay thx for comments.

What I was after is something along the lines of Eebster: only being able to face in one direction, therefore only being able to move or attack in that direction, such that you cant physically attack a unit that is not directly in front of you. Still possible?

Edit: Useless information.

Someone would need to confirm what a units attack angle is, as I clearly don't know anymore.

[MauranKilom]

GUI-Action: Animation - Change Unit Turn Speed -> Set it to 0. Works perfectly.
Jass: call SetUnitTurnSpeedBJ( unit, 0.00 )

Have to test what influence this has on attacks. But the unit can only run in a straight line for now. I'll collect my findings below.

Attacking is still possible in a limited angle. Don't know how it is determined though.

Art - Propulsion Window has some interesting effects. If you set it to 90° then the unit will not do anything when ordered to go behind itself, but move forward when ordered to somewhere in front of it. Similarly, if it's 180° the unit will move forward no matter where you order it to go, which interacts in a funny way with the wc3 pathing (the engine doesn't consider stuff in front of you an obstacle because you should turn around first, thus you start moving. But since you don't turn around, you start moving through stuff in front of you).

The turnspeed isn't exactly 0, but it's close. You'll need 2 minutes to turn 180° i believe.

Also, reporting for move to Programming.

[chick3nfist]

Or you can just trigger everything. Inelegant programming though.

[SoletLuna]

Reeeeeeeeeeports, eh, moved.

If you have tested it you will know that propulsion window has nothing to do with attack angle and is another story.


From my tests a unit can attack a target if the angle between its facing and center of the target is less than ~11.756°.

This seems to be a constant for all units except the ones with Movement - Speed Base 0 (and the ones that have a root ability with rooted turning boolean false and are in rooted state).

Note that the facing of the model does not always show the actual facing of the unit (extreme example would be jakiro). While spell casting, attacks and running use the actual facing of the unit, GetUnitFacing(unit u) returns the facing of the model.

I found that information about Propulsion window in a quick search around the web. I then proceeded to test it and i removed it as soon as i realized that this information was wrong. Refer to my sig.

[EebstertheGreat]

I can't find any mathematical justification for 11.756°. I wonder where it comes from.

Anyway, PropWin is clearly buggy, like so many fields.

No idea .
And its something like 11.755xxxxxxxx. But feel free to retest, there is too little test stuff goin on these days an my fingers still bleeding from hitting the test button in WE that often the last years ..

Hm, I think it does what its supposed to do..
