[Trigger] Custom Chain Lightning

[nedio95]

Greetings
I have been working on a custom chain lightning spell so I can use a heroes stats for the damage. The thing is that what I have done so far crashes the game after a few uses (~after 3 uses) which is highly undesireable as you can suggest.
I am not much into jass and I have no idea if the custom script is ok (I suppose it is as I have only edited a script from another post around) or I am doing something whrong on fundamental level in war3.

So can someone point out my mistake ? Or suggest a better way of creating the desired effect ?

Thats what I have done so far:

GUI code

• Chain Lightning
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Chain Lightning New Far Seer
  • Actions
    • Set CL_Caster = (Triggering unit)
    • Set CL_Owner = (Owner of CL_Caster)
    • Set CL_Target = (Target unit of ability being cast)
    • Set CL_Level = (Level of Chain Lightning New Far Seer for CL_Caster)
    • Set CL_Damage = (Real((CL_Level x (50 + (Intelligence of CL_Caster (Include bonuses))))))
    • Set CL_Count = (3 + CL_Level)
    • Set CL_Point = (Position of CL_Target)
    • Unit - Cause CL_Caster to damage CL_Target, dealing CL_Damage damage of attack type Spells and damage type Normal
    • Unit - Create 1 Chain Lightning for CL_Owner at CL_Point facing Default building facing degrees
    • Set Temp_Unit = (Last created unit)
    • Unit - Add a 1.00 second Generic expiration timer to Temp_Unit
    • Unit - Add Chain lightning dummy buff to Temp_Unit
    • Unit - Set level of Chain lightning dummy buff for Temp_Unit to CL_Level
    • Unit - Order Temp_Unit to Undead Banshee - Curse CL_Target
    • Trigger - Turn on CLLoop <gen>

• CLLoop
  • Events
    • Time - Every 0.40 seconds of game time
  • Conditions
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • CL_Count Greater than 0
      • Then - Actions
        • Set TempGroup = (Units within 350.00 of CL_Point matching ((((Matching unit) has buff Lightning Strike ) Equal to False) and ((((Matching unit) belongs to an enemy of CL_Owner) Equal to True) and (((Matching unit) is alive) Equal to True))))
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Number of units in TempGroup) Greater than 0
          • Then - Actions
            • Set CL_Count = (CL_Count - 1)
            • Set CL_Target = (Random unit from TempGroup)
            • Set TempPoint = (Position of CL_Target)
            • Set CL_Damage = (0.85 x CL_Damage)
            • Unit - Cause CL_Caster to damage CL_Target, dealing CL_Damage damage of attack type Spells and damage type Normal
            • Lightning - Destroy CL_Light
            • Custom script: set udg_CL_Light = AddLightningEx("CLPB", true , GetLocationX(udg_CL_Point), GetLocationY(udg_CL_Point), GetLocationZ(udg_CL_Point) + 70, GetLocationX(udg_TempPoint), GetLocationY(udg_TempPoint), GetLocationZ(udg_TempPoint) + 70)
            • Custom script: call RemoveLocation(udg_CL_Point)
            • Set CL_Point = (Position of CL_Target)
            • Custom script: call RemoveLocation(udg_TempPoint)
            • Unit - Create 1 Chain Lightning for CL_Owner at CL_Point facing Default building facing degrees
            • Set Temp_Unit = (Last created unit)
            • Unit - Add a 1.00 second Generic expiration timer to Temp_Unit
            • Unit - Add Chain lightning dummy buff to Temp_Unit
            • Unit - Set level of Chain lightning dummy buff for Temp_Unit to CL_Level
            • Unit - Order Temp_Unit to Undead Banshee - Curse CL_Target
          • Else - Actions
            • Lightning - Destroy CL_Light
            • Custom script: call DestroyGroup(udg_TempGroup)
            • Custom script: call RemoveLocation(udg_CL_Point)
            • Custom script: call RemoveLocation(udg_TempPoint)
            • Trigger - Turn off (This trigger)
      • Else - Actions
        • Lightning - Destroy CL_Light
        • Custom script: call DestroyGroup(udg_TempGroup)
        • Custom script: call RemoveLocation(udg_CL_Point)
        • Custom script: call RemoveLocation(udg_TempPoint)
        • Trigger - Turn off (This trigger)

Destroying a null lightning can cause a crash.

You destroy it before creating it, learn to use move lightning.
