Facing of Unit

[hdm]

A unit starts the effect of an ability

This ability creates two units


Unit 1| Caster | Unit 2


How to make units face the angle opposite to the caster ? Mean

<--- Face here Unit 1| Caster | Unit 2 ----> face here

Actions
    Set PointCaster = (Position of (Triggering unit))
    Set Point1 = (PointCaster offset by 256.00 towards (Facing of (Triggering unit)) degrees)
    Set Point2 = (PointCaster offset by 256.00 towards ((Facing of (Triggering unit)) + 180.00) degrees)
    Unit - Create 1 Footman for (Owner of (Triggering unit)) at Point1 facing (Angle from PointCaster to Point1) degrees
    Unit - Create 1 Footman for (Owner of (Triggering unit)) at Point2 facing (Angle from PointCaster to Point2) degrees

You can try something like the above.

That will only work if the caster is facing 0 to 180 degrees. The Set Point2 part that is.
Because if the units i facing 181 degrees Point2 will equal to 361 degrees and that is not possible.

You have to throw in an If/then/else.
Set Real2 = (PointCaster offset by 256.00 towards ((Facing of (Triggering unit)) + 180.00) degrees)
If - Real2 is Greater than 360
Then - Set Real2 = Real2 - 360
Else -

And go from there.

361 will just work as the same as 1, dont worry.

No it wont. Wc3 only works in 360 degrees.

No it wont. Wc3 only works in 360 degrees.

Yes it will.Sin30 = Sin390 = Sin750 ..... so since facing is also about angles it won't change result.

It seems you are correct.
I just tried this:

• Untitled Trigger 001
  • Events
    • Player - Player 1 (Red) types a chat message containing qw as An exact match
  • Conditions
  • Actions
    • Unit - Order Tauren Chieftain 0000 <gen> to Orc Tauren Chieftain - Shockwave ((Position of Tauren Chieftain 0000 <gen>) offset by 256.00 towards 450.00 degrees)

And he does indeed cast towards 90 degrees.
I'm sorry.

Though I am pretty sure I have encountered problems with degrees above 360. Some cone spell if memory serves me.

This is only true if you compare 'unit facing angle' with 'angle between points'.
In WC3, the latter detects angle between -180 and 180. The former detects angle between 0 and 360. So problem will only arise if you use real comparison between both types of angle.
