Trigger shortcut needed

[Blademaster_X]

I need a fast way to make this trigger work for every player in the game. I tried doing "Set Target[Player number of (Owner of Target of Ability Being Cast)] = Target of Ability Being Cast", but then I realized after 480 seconds you can't refer to the target of the ability being cast anymore. So is there a more efficient way than making this trigger for every player(replacing the numbers in the arrays with the number of the player)?

Event:
Unit - A unit Starts the effect of an ability
Condition:
(Ability being cast) Equal to Storm Bolt
Action:
Set Target[1] = (Target unit of ability being cast)
Wait 480.00 seconds
Unit - Create 1 Dummy Unit 1 for Player 12 (Brown) at (Position of Target[1]) facing Default building facing degrees
Unit - Hide (Last created unit)
Unit - Order (Last created unit) to Undead Dreadlord - Sleep Target[1]
Wait 0.01 seconds
Unit - Remove (Last created unit) from the game
Wait 20.00 seconds
Game - Display to player group(Owner of Target[1]) lots of text...
Wait 20.00 seconds
Unit - Add Avatar to Target[1]
...

local variables!

1. make a (global) unit variable called "Target"

Event:
    Unit - A unit Starts the effect of an ability
Condition:
    (Ability being cast) Equal to Storm Bolt
Action:
    Custom script: set udg_Target = GetSpellTargetUnit()
    [now refer to the Target variable as normal in the GUI]
    Wait 480.00 seconds
    Unit - Create 1 Dummy Unit 1 for Player 12 (Brown) at (Position of Target) facing Default building facing degrees
    Unit - Hide (Last created unit)
    Unit - Order (Last created unit) to Undead Dreadlord - Sleep Target
    Wait 0.01 seconds
    Unit - Remove (Last created unit) from the game
    Wait 20.00 seconds
    Game - Display to player group(Owner of Target) lots of text...
    Wait 20.00 seconds
    Unit - Add Avatar to Target

Thanks Darg. Now I know how to use local variables

 

[Darg]

Well this particular case is actually more like "local global variables", and not local variables in their purest form.

Also, beware of a JASS bug that doesn't allow you to do more than 1 "local global variable" per trigger.

I have more questions about local global variables:
1. Can I use the same local variables in other triggers to refer to that same unit? In other words, can I use "Target" in another trigger and it will still refer to the same unit even after the trigger has run many times for other players?
2. This particular local global variable has been set to "GetSpellTargetUnit ()". How do you know to set it to this string? Is there a place where I can look up the strings for other things like Casting Unit, etc.?
