[Trigger] Making a shockwave like spell as a trigger

[Mallaboro]

I'm trying to make a spell like shockwave which deals damage to all units in a straight line.
I've never made a spell like this before, so I'm asking for help.

• Voltric Shot
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to Voltric Shot (Heroes)
  • Actions
    • -------- Math --------
    • Set Spell_VoltricShotDamage = ((Level of (Triggering unit)) x 50)
    • -------- Points --------
    • Set Spell_VoltricPoint = (Target point of ability being cast)
    • Set Spell_VoltricShotCasterLocatio = (Position of (Triggering unit))
    • -------- Angles --------
    • Set Spell_VoltricShotAngle = (Angle from Spell_VoltricShotCasterLocatio to Spell_VoltricPoint)
    • -------- Group --------
    • Set Spell_VoltricShotGroup = (Units within 100.00 of Spell_VoltricShotCasterLocatio)
    • -------- Actions --------
    • Unit Group - Pick every unit in Spell_VoltricShotGroup and do (Actions)
      • Loop - Actions
        • Unit - Set life of (Picked unit) to ((Life of (Picked unit)) - (Real(Spell_VoltricShotDamage)))
    • -------- Desecrate Variables --------
    • Custom script: call DestroyGroup(udg_Spell_VoltricShotGroup)
    • Custom script: call RemoveLocation(udg_Spell_VoltricPoint)
    • Custom script: call RemoveLocation(udg_Spell_VoltricShotCasterLocatio)

Currently the spell hits all units around the caster. (Thats only there cause I can't find out how to damage all units in VoltricShotAngle

You need to make it in a line. To do this, use another periodic trigger that picks units and damages them further away from the caster.

This is clever. Not exactly what I was after, but I can learn from this. Thanks very much. + rep and internet hi-fives

you will need one triger to set all spell constants and other whit periodic action.
