[Solved] More damage if the target is not facing the caster

[TheAyalalalalon]

Hello
This is a fast question
I am trying to make a triggered ability to make more damage if it hits a unit from behind (dont mind the projectile, is an instant ability based on cripple)

You could compare angle between target and caster with the facing of the target.

This is the first trigger that came to my mind. Result of 180/-180 means you are casting in front of the target, 90/-90 is from the side and 0 is from behind. So you can check if abs(result) < 90 for example.
Trigger leaks of course.

• SpellDirection
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Cripple (Neutral Hostile)
  • Actions
    • Set AngleBetween = (Angle from (Position of (Target unit of ability being cast)) to (Position of (Triggering unit)))
    • Set AngleTarget = ((Facing of (Target unit of ability being cast)) - 180.00)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • AngleTarget Less than 0.00
      • Then - Actions
        • Set AngleTarget = (AngleTarget + 360.00)
      • Else - Actions
    • Set Result = (AngleBetween - AngleTarget)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • Result Less than -180.00
      • Then - Actions
        • Set Result = (360.00 + Result)
      • Else - Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • Result Greater than 180.00
      • Then - Actions
        • Set Result = (360.00 - Result)
      • Else - Actions
    • Game - Display to (All players) the text: (String(Result))

Here's a small script I rewrote into GUI (to make it usable in normal editor) from MoCo works (it was originally written in vJass). If you use JNGP, I recommend use his [vJASS] - [Snippet] Field of View (IsUnitInSight + IsUnitBehind) which is the original version I based the script from (it's quite easy to implement, just a line of custom script will do the job, and works much more efficiently).

It is able to detect if the unit is behind a unit.

Thank you all

I had a problem implementig this trigger in another map

• IsUnitInView GUI
  • Events
  • Conditions
  • Actions
    • Set FoVView = (FoVView x 0.50)
    • Set FoVFacing = (Facing of FoVObserver)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • FoVObserverScan Equal to True
      • Then - Actions
        • Custom script: set udg_FoVAngle = bj_RADTODEG*Atan2(GetUnitY(udg_FoVTarget) - GetUnitY(udg_FoVObserver), GetUnitX(udg_FoVTarget) - GetUnitX(udg_FoVObserver))
        • Custom script: set udg_FoVUnitInSight = not (RAbsBJ(udg_FoVFacing - udg_FoVAngle) > udg_FoVView and RAbsBJ(udg_FoVFacing - udg_FoVAngle - 360.) > udg_FoVView)
      • Else - Actions
        • Custom script: set udg_FoVAngle = bj_RADTODEG*Atan2(GetUnitY(udg_FoVObserver) - GetUnitY(udg_FoVTarget), GetUnitX(udg_FoVObserver) - GetUnitX(udg_FoVTarget))
        • Custom script: set udg_FoVUnitBehindUnit = not (RAbsBJ(udg_FoVFacing - udg_FoVAngle) > udg_FoVView and RAbsBJ(udg_FoVFacing - udg_FoVAngle - 360.) > udg_FoVView)

I can not enable the trigger. It displays on all the custom scripts an "Expected a Variable name" error

There's another trigger with the missing variables inside or you can just manually create them in variable editor :
FoVAngle (Real)
FoVUnitInSight (Boolean)
FoVUnitBehindUnit (Boolean)
(Follow the case correctly!)

The VAngle was the missing one, but now is working
Thank for your attention
