How can I make a spell that damages(or effects in anyway) only undead units? For example I want a crushing wave spell that instantly kills any undead units in front of it, but does no harm to living enemies.

You would have to trigger it.

Here's a Custom Shockwave spell I made, it's very easy to configure. I designed it using Dynamic Indexing: Visualize: Dynamic Indexing
  • Custom Shockwave Cast
    • Events
      • Unit - A unit Starts the effect of an ability
    • Conditions
      • (Ability being cast) Equal to Custom Shockwave

To configure the settings to your liking:
Simply edit the settings listed under -------- CONFIGURE Settings: -------- in the Custom Shockwave Cast trigger:
  • Actions
    • -------- CONFIGURE Settings: --------
    • Set VariableSet SW_Damage[SW_Index] = 100.00
    • Set VariableSet SW_DamageType[SW_Index] = Magic
    • Set VariableSet SW_AttackType[SW_Index] = Spells
    • Set VariableSet SW_Speed[SW_Index] = 25.00
    • Set VariableSet SW_Height[SW_Index] = 60.00
    • Set VariableSet SW_AoE[SW_Index] = 200.00
    • -------- --------
    • -------- Counter is increased by 1 every 0.03 seconds. Once this Counter reaches SW_CounterMax the missile is destroyed --------
    • -------- By default I set CounterMax to 40, which is equal to 1.20 seconds ---> 0.03 * 40 = 1.20 --------
    • Set VariableSet SW_CounterMax[SW_Index] = 40
You can also edit the If - Conditions in the Custom Shockwave Timer trigger to modify the Targets Allowed. By default I have settings similar to the standard Shockwave ability:
  • Unit Group - Pick every unit in (Units within SW_AoE[SW_Loop] of SW_Point[0].) and do (Actions)
    • Loop - Actions
      • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        • If - Conditions
          • ((Picked unit) belongs to an enemy of (Owner of SW_Caster[SW_Index]).) Equal to True
          • ((Picked unit) is alive) Equal to True
          • ((Picked unit) is A ground unit) Equal to True
          • ((Picked unit) is Magic Immune) Equal to False
          • ((Picked unit) is hidden) Equal to False
          • ((Picked unit) is invulnerable) Equal to False
          • ((Picked unit) is in SW_HitGroup[SW_Loop].) Equal to False
        • Then - Actions
          • Unit Group - Add (Picked unit) to SW_HitGroup[SW_Loop]
          • Unit - Cause SW_Caster[SW_Loop] to damage (Picked unit), dealing SW_Damage[SW_Loop] damage of attack type SW_AttackType[SW_Loop] and damage type SW_DamageType[SW_Loop]
        • Else - Actions

I attached pictures to show you how to modify the spell to kill Undead units instantly.

The attached map requires the most recent version of Warcraft 3.


Edit: Updated the map to fix some minor bugs. Map name changed from Custom Shockwave to Custom Shockwave v.1.
