Hey guys, i have lots of trigger based missile abilities, right now i'm using create unit -> launch effect and adding thread. But there are few situations when i need get owner of a missile that was launched through data (without thread that inherit caster unit) so if i store the creator's id in missile custom value how can i reference this unit? If i will use data tables would it lag like a hell? What are your advises?

@abvdzh: Go

If I'm understanding you correctly, it seems like you would need to give the creator unit an ID in a custom value (or otherwise a global variable,) then set the missile's custom value to that ID. Then you can run a check like "Custom Value 1 of Missile == Custom Value 1 of Shooter" to get your match.

If, for example, the missile kills another unit and you want to add minerals for the killing player, you could do something like this (pseudo-code):

Events
    Any Unit Dies
Conditions
    Unit Type of (triggering unit) == Guy With A Missile Launcher
    Unit Type of (Killing unit) == Missile
Variables
    Killer (unit) = (no value)
Actions
    Pick each unit in Units of Type 'Guy With A Missile Launcher' in Entire Map owned by Any Player and do
        Actions
            If
                Custom Value 1 of (Picked unit) == Custom Value 1 of (Killing unit)
            Then
                Set Killer = (Picked unit)
                Modify player (Owner of Killer) minerals: +1
                Send Actor Message to Killer: PlayAnim Dance LoopForever
                Break
            Else

You can use the "Unit Tag" function to return a unique integer associated with a unit.

You can't access a unit by its tag without looping through all the units and checking for the correct tag, or using a data structure to store the unit in, e.g. a data table as you suggested.

There is a UnitFromId(int) function in galaxyscript, but it only works with units that were pre-placed in the editor.

Thanks, used checking loop solution
