Question about triggers and variables

[world23wc3]

Hi!

I've been quite unsure about this question I've had for some time now and I thought that it was time to ask for help now.
Let's say that I have this trigger

• Example
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Firebolt (Neutral Hostile)
  • Actions
    • Set example_unit = (Target unit of ability being cast)
    • Wait 20.00 seconds
    • Unit - Kill example_unit

What if the trigger is runned twice but from different units, Will it create two instaces of the variable "example_unit" or will the first targeted unit be set to example unit and then the other one override the variable with it's targeted unit? Do I need to create many IF, THEN ACTIONS, ELSE ACTIONS?
Please help me, I hope I made myself as clear as possible.

afaik just the second "example_unit" dies. The "example_unit" gets overridden.

and thats where local variables come in handy. they are pretty easy to use via custom scripts aswell.

You could do it this way.

• Example
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Firebolt (Neutral Hostile)
  • Actions
    • Custom script: local unit Target = GetSpellTargetUnit()
    • Wait 20.00 seconds
    • Custom script: set udg_example_unit = Target
    • Unit - Kill example_unit
    • Custom script: set Target = null

This will ensure that example_unit will refer to the targeted unit 20 seconds after casting.
