Looping..

I was referencing Lord Vexorian's mech map and I see this:

"Custom script: loop" in conjuction with "Custom script: exitwhen"

Where are those or what series of trigger bits are those representing? I would expect "custom script: loop" to be a fairly obvious "loop" action.. but i can't find anything that says "loop" anywhere except with the integers, but I don't need intergers.. I just need it to loop until a given variable hits a number. Nevermind, that's just making things confusing..

How do I loop a set of actions, that's my question.

you can loop actions with the use of any Variables and array, but what kind of loop do you need? Can you give a exemple ?

kinda sounds like you dont need integers but you do

You can say that again. I mean, it's damn simple really. I'm looking at Lord Vexorian's spell and thinking "There's GOT to be a simple "loop this until the given conditions are met".. But I can't seem to find it. Look at Lord Vexorian's Mech spell map, and look at the anti-materia spell to see what I'm talkin about.

A loop in JASS looks like this:

Using GUI with custom script you can make a loop like this, it will continue to loop until "tempBool" becomes equal to true.

The == true in your exitwhen is not necessary.
exitwhen udg_tempBool
is enough (and means the same).

You got me confused. How exactly does that trigger work? Like how does it determine how many times it loops?

Under said JASS loop, it loops forever until the exit value becomes true.

Yeah, now you see what I was getting at. What you did Grater is exactly how I got around my little gui issue. I was just wondering if there was sucha thing within WE's gui trigger menu's. That little loop thing has some f'cking mad potential though.. to be able to look anything until a given condition is met.. and not just based on integers or something.. nice..

Guess why we use JASS? heh, as sadly, GUI doesn't offer you this looping-potential -_-

It's a personal preference issue, I find it helps my understanding of code to make things like that explicit and it keeps boolean comparisons consistent with other comparisons (which always have a RHS and LHS). Altough I'm aware such practises dash my chances of ever winning an obfuscated c competetion :)

Well, I guess it also depends on the name of the variable. As an example if I have 2 booleans named attacking and defending and the first one is true if an attack is running, the second if you currently defend.
Then I consider it more understandable if I have:
if attacking then
// do something
elseif defending then
// do something
endif

instead of:
if attacking == true then
//
elseif defending == true then
//
endif

Its also slightly slower to do it the second way because first what happens is that your boolean variable is storing a 0 or a 1
If (attacking)then is actually reading it as If(1 continue, 0 quit)
But now your throwing in another expression it has to evaluate.
if(attacking==true)then
It now has to convert that into a 1 or a 0 then proceed onward with the path choosing operator. Its an extra step and it'll slow you down.

ok, it is possible to do some loops with the regular functions, here is an example where I spawn any unit in a specific region. This works fairly well excaept if you have more than one unit in the region at a time it dosent stop right but Im sure there are ways around it, just havent been working on this map becuz not to many ppl like it. :\

there ya go sans, hope it helps.
