[JASS] What is this function for?

What is this function for?

TriggerRegisterVariableEvent

 

[Maker]

When a variable's value becomes something the trigger fires. It only works for reals.

For example if you register variable called Deaths, becomes equal to 0. When the variable's value becomes 0, the trigger fires.

If it is already 0, and it is set to 0, nothing happens. If it is 0, you set it to 1, and then back to 0, the trigger executes.

GUI Damage Detection systems and the GUI events that I use take advantage of that function.

However, in vJass/JASS you don't need such a thing.

TriggerRegisterVariableEvent has only one use in vJass other than Events:

library CoolStuffInThisLib

    globals
        real dontEdit = 9001
    endglobals

    private struct Init extends array
        private static method run takes nothing returns boolean
            call DisplayTimedTextToPlayer(GetLocalPlayer(), 0, 0, 60, "Tard!")
            return false
        endmethod

        private static method onInit takes nothing returns nothing
            local trigger t = CreateTrigger()
            call TriggerRegisterVariableEvent(t, "dontEdit", NOT_EQUAL, 9001)
            call TriggerAddCondition(t, Condition(function thistype.run))
            set t = null
        endmethod
    endstruct
endlibrary

So epic, it can't even compile.

I think that instead of constant reals we should use that.
More sphagetti code can't be bad after all.

Hell yeah
