[Trigger] End Loop

[defskull]

How can I end a loop, prematurely without the process going to the check of "exitwhen" ?

Let's say;

loop
exitwhen i > j
IF SOMETHING
END THE LOOP
endloop

How can I end that loop without the process going for a check of "i > j" ?

Maybe you can set the i to be equal to the j right when the condition is met.

That's what I want to avoid, that's why I highlight those text - in yellow.

Oh I see. My bad

Well there are a few ways to get around like clearing the entire enum group or killing the unit current being iterated.

There isn't a one-size-fits-all solution as far as I know

EDIT: But it all goes down to the condition in the end so I myself think that there isn't a way to skip that

You need the exitwhen line.

But you don't need the integer variable.

You can, for example, change it to a boolean and check if its true or not.

globals
    boolean abc = false
endglobals

function Whatever takes nothing returns nothing
    loop
        call BJDebugMsg("test")
        if abc == true then
            exitwhen true
        endif
        call PolledWait(0.2)
        set abc = true // to make doom happy..^^
    endloop
endfunction

@SeriousEnemy: or you can set the boolean to be true inside the loop. It also works

I know, it was just an example^^

Ah I forgot that using while loop @@.
All this while, I've been using for loop.

Thanks to you guys

I'd just like to note that this also works:

function LoopFunction takes nothing returns nothing
    local integer i = 0
    
    loop
        exitwhen i >= 10 // Regular exitwhen
        
        // Action block 1
        
        if boolexpr then
            // Exiting the loop
            exitwhen true
        endif
        
        // Action block 2
        
        set i = i+1
    endloop
endfunction

In case you want to exit the loop after Action block 1, but still do something special (like giving an item to a unit or whatever).

You don't see this very often though

boolexpr, doesn't that generate leak ?
I don't know if I heard it right, or not.

It will leak when returning null.
No leak when true of false.

Wow never know about such thing. Thanks for sharing

I'm just using it here as a substitute for anything you fill in by the way.
Something like myBool == false, or myUnit1 == myUnit2. Anything along those lines.

from I dont know which patch null boolexprs wont null(the proof of this is using nulls as boolexpr to groupenum functions and triggerevents, they even stated several times(users) that it not longer leaks), even Blizzards BJS uses null as boolexpr to trigger events
however to if you should rather say boolean than boolexpr
trying to fit boolexpr within if and then will cause compiler errors
Cannot convert boolean to boolexpr

It will leak when returning null.
No leak when true of false.

As far as I know, the latest wc3 patch has fixed this. boolexpr and filterfunc do not leak anymore.
