Timed Lightning in custom script

[Manasurge]

Got a trigger which i do not know how to make the Lightning effects get a lifespan(duration). I want them to last for 0.7 seconds but it doesn't seem to exist a premade option to do so.

I was wondering if anyone knew if you could do it in custom script and how.
(I got a feeling it can only be done in jass.)

im new and have no experience what so ever, trial and error, that's how i learn. Tell me if i made anything fataly wrong (except Lightning, i know they will bug)

The easiest way in GUI to set duration for lightning effects is using dummy units, in my opinion.
When you create a lightning, create a dummy unit anywhere and attach lightning to dummy. Then add an expiration timer to dummy and destroy lightning upon dummy's death.

• Set Loc1 = Lightning source location
• Set Loc2 = Lightning target location
• Lightning - Create a Chain Lightning - Primary lightning effect from source Loc1 to target Loc2
• Unit - Create 1 DummyUnit for Player 1 (Red) at Loc1 facing Default building facing degrees
• Unit - Add a 1.00 second Generic expiration timer to (Last created unit)
• Hashtable - Save Handle Of(Last created lightning effect) as 0 of (Key (Last created unit)) in YourHashtable
• Custom script: call RemoveLocation(udg_Loc1)
• Custom script: call RemoveLocation(udg_Loc2)

• Untitled Trigger 002
  • Events
    • Unit - A unit Dies
  • Conditions
    • (Unit-type of (Triggering unit)) Equal to DummyUnit
  • Actions
    • Lightning - Destroy (Load 0 of (Key (Triggering unit)) in YourHashtable)

Don't forget to clear the child hashtable.
