[JASS] How to exit loop?

[SupremeGrandRuler]

I want 2 different exit loop functions:

exitwhen Picked Unit has Buff[Integer A]
exitwhen MyBoolean = True

I'm not sure how to do it though. Any help appreciated

 

[KhaosMachine]

exitwhen = if

An example:

local integer i = 0
local boolean exit = false
loop
    exitwhen i >= 10 or / and exit
    set exit = GetUnitAbilityLevel(XUnit, XAbility) > 0
    set i = i + 1
endloop

I tried that first but it's not working for me.

From what I understand;

I want 2 different exit loop functions:

I believe you should use OR function, right ?
Either condition should be fine, exit loop either your picked unit has buff, or your Boolean is equal to True.

Or the other way around ?
Both must be true ? (Picked unit has buff + Boolean is True) ?

No, no seperate. Each is for different loops.

So you mean each condition is not meant for each other ?
So this is somewhat 2 separate function, eh ?

If you want to check a certain condition over-time, direct loop is never the answer.

You should use the Event Time - Periodic Event so that you can evaluate the condition each time.

The method you currently used is a direct looping which checks the condition for several times (but in a single period) where you should constantly checking the condition, that's why we use that Event.

Let's say we take a 0.10 second of Periodic Time event.

So, each 0.10 second pass, you make a check, this way you will evaluate those conditions per 0.10 second.

There is no limit to the number of "exitwhen" clauses a loop can have in WarCraft III.

In programming languages like C this is obtained by using the "break" statement (which JASS does not have). The use is to allow early exits from complex loops without having to reach the end.

In simple loops you can often tie the logic together using the logical "and" and "or" operators.

Yes.

Basically, when a unit is struck by a projectile, I need to check if the unit has a buff on, then exit the loop as soon as a buff is found.

Did you even read my post below that ?

Yes. It wouldn't work for what I'm doing.

Posting some code for the others would be nice. (If you want to)
