[Trigger] Make unit face unit/point/angle instantly...

[Kingz]

Well i have a problem...
You see in my spells Tempest Dance and Ruinous Onslaught the caster moves fast towards the defined targets, now the problem is when i try to make them face the target, i tried the following:

• Unit - Make unit face target
• Unit - Make unit face position of target
• Unit - Make unit face (angle between position of unit to position of target)

All over 0.00 seconds and even tried 0.01 seconds but it doesn't work.
And yes i tried moving the unit instantly and facing the target/position of target/(angle between position of unit to position of target).
So any ideas?
The user who helps me will get +rep .

Did you set the targeted unit to Unit Variable 'target' and the caster to the Unit Variable 'unit' correctly?

 

[Lord_BoNes]

By memory, there is no way to make a unit turn "instantly". But, I think that there is a workaround... a "near-instant turn". I just can't remember how to do it in GUI

I'm certain that someone around here will be able to help.

Tried this?

• Unit - Move (Triggering unit) instantly to (Center of (Playable map area)), facing Default building facing (270.0) degrees

Move the unit to where its standing though.

 

[Bobo_The_Kodo]

you cant change their facing instantly, thats a fact. ( unless you use a dummy & SetUnitLookAt )

This will issue a stop order since you are using SetUnitPosition.

I don't think that there is a decent way to change a unit's facing instantly without doing that, though. You can use a very small time interval with SetUnitFacingTimed, but that is still not instantaneous (it has a maximum rotation speed)

 

[Soga-]

You could remove and recreate the unit facing in a direction.

 

[idodik]

Technically the trigger should work, but paste the whole lot of it so we can know please.

 

[Lord_BoNes]

You could remove and recreate the unit facing in a direction.

There would unforeseen consequences...
EI: Enemy units currently attacking the "turning unit" would temporarily stop, for a moment while they rethink their options. Any units following the "turning unit", would stop following immediately (the unit they were following no longer exists). You'd have to re-assign all the variables associated with the unit, if you use LocalHandleVars, then you're screwed, if a timer is going for the unit at the same time. You have to set the unit's health / mana / items / abilities = lots of stuffing around (easy to do, but still, stuffing around). And other possibilities, that I obviously can't foresee.

You could do:

call SetUnitTurnSpeed(unit, 999)
call SetUnitFacingTimed(unit, direction, 0.001)
call SetUnitTurnSpeed(unit, GetUnitDefaultTurnSpeed(unit))

Or possibly the way that Bobo_The_Kodo described: Create a dummy, and use SetUnitLookAt() to make your turn.

Hope that this is useful.

 

[Palaslayer]

what is the action make unit face 'instantly' for if u cannot face instantly?

change units turning rate to a very high figure and order it to attack the supposed target, the nmove it, which will interrupt the attack as far as i know

 

[Kingz]

Okay i already said i tried moving the unit, and yes the unit is stored into a variable, i change it's facing every 0.02 seconds and it ain't efficent enough...
Please tell me there are way's to do that without dummy units....
@Lord_Bones
I will try what you said though...

 

[idodik]

Hmm. The only type of unit that can't turn even with triggers (although I'm not sure about that) is buidings. Am I right? So technically if you remove the building classifation it should work correctly.
Just in case your unit was a building.

He doesn't mean he can't get it to turn. He just can't get it to turn instantly.

 

[Lord_BoNes]

@Kingz: How did it go? Have you solved your problem, or are there unforeseen circumstances?

 

[Kingz]

Still the same, i just cannot belive that there is a option in WE that doesn't work properly...

 

[redscores]

All you people are wrong.... there is a instant facing set.... it is a JASS function I used for my missile system... even bobo... i thought you are good.

call SetUnitFacing(unit, angle)

 

[Avator]

If that surprises you, then you still need some more experience in using the WE. There are plenty of stuff that are illogical in it.

 

[redscores]

Try my function... it works....

 

[Kingz]

If that is so why doesn't this work:

• call SetUnitFacing(udg_RO_caster[udg_RO_integer[2]], AngleBetweenPoints(udg_RO_caster_point[udg_RO_integer[2]], udg_RO_target_point[udg_RO_integer[2]]))

 

[redscores]

It works dude... just look at my system: GUI MUI Missile System V1.03 - The Hive Workshop - A Warcraft III Modding Site

Test the homing single target missile, it heals on allieds or deals damage to enemies, let one of your units patrol and cast it on the unit..., it will follow with a perfect facing towards the unit, and that system uses that function... and now be silent.

 

[RolePlaynGamer]

redscores, SetUnitFacing doesn't make an unit face an angle instantly.
Not even if the unit has locust.

 

[redscores]

It does, I use it in that map.... if you look at it you will understand...

 

[Kingz]

And would you kindly explain to us mortals what is wrong with the sample i provided, and yes the points are set into the variables i double checked them...

 

[redscores]

Just check how I did it in the map, easy peasy? O,o.

 

[RolePlaynGamer]

Well, you're wrong on this one, I bet you updated the facing several times/second.

Back ontopic, I've actually been wondering how to make an unit face an angle instantly lately, perhaps I'll look into it and post my results.

Kingz, your sample doesn't work. Maybe there're some gameplay constants for max turn rate, maybe it's hardcoded into Warcraft.

 

[Kingz]

I try to change it every 0.02 seconds and it still isn't good...

 

[redscores]

You dont even look on my example... bad luck for you, so you will never have a smooth face change.

 

[Kingz]

@Redscores
Checking it out, i will reply tommorow...

 

[RolePlaynGamer]

Smooth?
We're trying to set a unit facing instantly.
And give up your theory. SetUnitFacing doesn't set an units facing instantly.

 

[Lord_BoNes]

SetUnitFacing() doesn't set unit facing instantly.

@Redscores: Your system does appear to turn instantly... but, it really doesn't. It's just close enough to fool the eyes. We are after an "instant" turn.

@RolePlaynGamer: There isn't a gameplay constant that caps the turn rate I thought that there was, but I can't find it.

Has anyone tried SetUnitFacingTimed() with a negative duration? It's just a thought that I had.

 

[Kingz]

Saw your missile system redscores and it didn't help at all...

 

[Xarian]

Negative duration has the same effect as a duration of 0, 0.01, or anything else so small that it hits the turn speed cap.

The only way I know to do it involves using SetUnitLookAt and moving whatever unit that it's facing using SetUnitX/Y. That doesn't change the actual facing, just what it appears to be looking at...

 

[Kingz]

Well that doesn't help...

 

[Quantum_Menace]

The turn speed limit seems related to the unit's "Art - Orientation interpolation" value. Most units have a value of 0, which is the fastest, and setting it higher forces a slower turn speed.

Unfortunately setting it to a negative value doesn't help, as it appears to default back to 0. The same thing happens with values over 8.

I'm guessing this is the system that forces the turn speed limit, and Blizzard didn't seem to leave any way to bypass it.
