[Trigger] Angle Problems

[dm251]

Well.. I wanna Do a spell that hits units in front of him.
An example or Image of it is this one..

The problems are.
I cant find the proper angle and the way to avoid other units getting damage except from the angle shown above.
Help?

Just enumerate the units and check if the angle between the caster and their location is like the facing of the caster + or - a value

• Trg
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
  • Actions
    • Set Points[1] = (Position of (Triggering unit))
    • Custom script: set bj_wantDestroyGroup = true
    • Unit Group - Pick every unit in (Units within 2000.00 of Points[1] matching ((((Matching unit) is A structure) Equal to False) and ((((Matching unit) is alive) Equal to True) and (((Matching unit) belongs to an enemy of (Owner of (Triggering unit))) Equal to True)))) and do (Actions)
      • Loop - Actions
        • Set Points[2] = (Position of (Picked unit))
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Cos(((Facing of (Triggering unit)) - (Angle from Points[1] to Points[2])))) Greater than (Cos(45.00))
          • Then - Actions
            • Special Effect - Create a special effect attached to the overhead of (Picked unit) using Abilities\Spells\Human\DispelMagic\DispelMagicTarget.mdl
            • Special Effect - Destroy (Last created special effect)
          • Else - Actions
        • Custom script: call RemoveLocation (udg_Points[2])
    • Custom script: call RemoveLocation (udg_Points[1])

There.

I'll try your Example Pharoah.. *Rep added*
Bdw, what does this script use?

Custom script: set bj_wantDestroyGroup = true

 

[sephiroth1234]

Pharaoh used that custom script line "set bj_wantDestroyGroup = true" to prevent the Unit Group to leak.

 

[BuRnInSpartan]

this doesn't work

 

[ikillforeyou]

Pharaoh, why do you use "Cos" wouldn't that return the same value at 4 different angles? it doesn't make sense to me.

Try getting rid of the Cos and seeing if it works.

Check this spell, I'm sure you'll find the answer.
