breakOut, breakTo - related to While?

[5133p39 16]

I need to break from a "while" loop, i now i can do it with the help of a simple boolean variable which value is later changed, causing the loop condition to be false:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">_done = false;

while{ not _done } do {

_done = true;

};

...but it would fit better my nit-picking nature if i could use some sort of 'break' command, instead of wasting resources by initializing more and more unnecessary variables.

On Biki i found two commands - breakOut and breakTo, but i can't figure how to use them. What exactly is their purpose?

They seem to work like this:

This counts to five:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

_x = 0;

while{true} do {

 scopeName "myLoop";

 _x = _x + 1;

 hint format["%1", _x];

 sleep(0.25);

 if(_x == 5) then {breakOut "myLoop"};

};

And this does the same thing:

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

scopeName "myRoot";

_x = 0;

while{true} do {

 _x = _x + 1;

 hint format["%1", _x];

 sleep(0.25);

 if(_x == 5) then {breakTo "myRoot"};

};

@Kegetys: I am speechless... THANK YOU!

Damn it!!!

So breakTo is doing something like a jump (#)

If i just could now this bevore then i could save a lot lot lot of time...

If I Interpret http://community.bistudio.com/wiki/breakTo correctly, breakTo breaks back "into" the scope named at breakto. So it probably doesn't jump to before the while loop at the place where the scope is defined, but in fact "returns" to the scope, and as such it doesn't jump, but just exits the while loop in Kegetys his example.

Interpreting his post, he seems to state the same.

Also consider exitWith which will exit from a foreach loop, which allows you to do things like....

foundThing=objNull;

{

currentThing=_x;

if ( _x == _anotherThing) exitWith{

foundThing=_x;

};

} foreach things;
