breakTo not working

[wiggum2 31]

Hi !

I just played around with the "breakTo" command but even the most simple script does not work...

private ["_x"];
scopeName "main";
_x = 0;
while{true} do {
_x = _x + 1;
hint format["%1", _x];
sleep 1;
if(_x == 5) then {breakTo "main"};
};

Now i got this from a "working" example Kegetys posted, but for me its not working.

The script counts to five and then stops doing anything.

I also tried many other things like making another scope or/and using breakOut...nothing works for me.

I call the script from a trigger with condition true and:

nul=execVM "whyohmygod.sqf"

Is the command broken ?

No it works as it should be.

The problem is that you have a wrong idea what it does.

It is NOT goto. It exits to the current scope to the given scope.

So in your example it will continue AFTER the while loop.

[CarlGustaffa 4]

Untested, but...

private ["_x"];
scopeName "main";
_x = 0;
while{true} do {
_x = _x + 1;
hint format["%1", _x];
sleep 1;
if(_x == 5) then {breakTo "main"};
hint "this should not show";
}; 
hint "this should show";

Does that work as I intended?

Also, if you only have one variable, you don't need to use private statement with array, private "_x"; would be enough. And since you're already initializing it at the beginning, strictly speaking it is not needed.

[wiggum2 31]

Ok, i got that...but the example on the BIKI sounds a bit differend:

scopeName "main"; 
while {true} do { 
scopeName "loop1"; 
while {true} do { 
scopeName "loop2"; 
if (condition1) then {breakTo "main"}; // Breaks all scopes and return to "main" 
if (condition2) then {breakOut "loop2"}; // Breaks scope named "loop2" 
sleep 1; 
}; 
sleep 1; 
};

The Breaks all scopes and return to "main" part sounds like goto for me...

And im still dont understand it really whats the differense between "breakTo" and "brekOut" is...

And this dont works:

private ["_x"];

_x = 0;

scopeName "main";
while{true} do {
scopeName "loop1";
while{true} do {
_x = _x + 1;
hint format["%1", _x];
sleep 1;
if(_x == 5) then {breakTo "loop1"};
hint "NOOOOOOOOOOOO";
};
scopeName "loop2";
while{true} do {
_x = _x - 1;
hint format["%1", _x];
sleep 1;
if(_x == 0) then {breakTo "loop2"};
hint "NOOOOOOOOOOOOOOOOOOOO";
};
};

hint "YEEEEEEEEEEEEEES";

I always get a error in line 15 (scopeName "loop2")

And i never see the "Yes" hint.

Do you use squint by Mac yet?

[Master85 1]

I always get a error in line 15 (scopeName "loop2").

you're trying to name the same scope twice (loop1 and loop2) - that's not allowed.

[wiggum2 31]

So, if breakTo is no "goto"...its basicly just something to break out of a while loop even if the actuall while condition is still true ?

And could you explain/show me a situation where i would need "breakOut" please ?

Do you use squint by Mac yet?

Yes, it shows me no errors with this script.

you're trying to name the same scope twice (loop1 and loop2) - that's not allowed.

Sorry, could you show that to me with a example, i dont understand what you mean.

[st_dux 26]

The Breaks all scopes and return to "main" part sounds like goto for me...

It goes back to the main scope; it does not go back to the line where you wrote the word "main"; that line is immaterial.

[nuxil 2]

Also keep in mind if you use BreakOut on most inner scopename you will terminate the script.

scopeName "main"; 
sleep 1;
hint "Main scope";
_A=0;
_B=0;
if(true) then 
{
   //this is a scope so we name it
   scopeName "if"; 
   //if (BREAK==0) then {_A=_A+1; breakTo "main";};
   if (BREAK==0) then {_A=_A+1; breakOut "if";}; // same as above. but breaks out of "if" scope and continutes
   if (BREAK==1) then {_A=_A+1; breakOut "main";}; // terminates the script
};
sleep 1;
hint format["%1\n%2",_A,_B];

@ nuxil

Thanks, i hope i got it now.

[wiggum2 31]

Sorry, but i got a problem with this again:

private ["_x"];

_x = 0;

scopeName "main";
while{true} do {
scopeName "loop1";
while{true} do {
_x = _x + 1;
hint format["%1", _x];
sleep 1;
if(_x == 5) then {breakTo "loop1"};
hint "NOOOOOOOOOOOO";
};
scopeName "loop2";
while{true} do {
_x = _x - 1;
hint format["%1", _x];
sleep 1;
if(_x == 0) then {breakTo "loop2"};
hint "NOOOOOOOOOOOOOOOOOOOO";
};
};

hint "YEEEEEEEEEEEEEES";

I always get a error in line 15 (scopeName "loop2").

Now master85 told me that:

you're trying to name the same scope twice (loop1 and loop2) - that's not allowed.

But why ?

What did i do wrong ?

Can someone show me what i have to change in my example to get it working without these error in line 15 ?

[sickboy 13]

You can also use if (condition) exitWith { /* some code */ };

to exit the current scope only; http://community.bistudio.com/wiki/exitWith

[wiggum2 31]

@ Sickboy

Yes, thats a good idea too.

But i would still like to know what is wrong with my example and why i "named the same scope twice" ?

[buliwyf 4]

http://community.bistudio.com/wiki/scopeName

...and in your first While{}do{}-loop you use scopeName twice!

private ["_x"];
_x = 0;
while{true} do {
scopeName "main";
while{true} do {
scopeName "loop1";
_x = _x + 1;
hint format["%1", _x];
sleep 1;
if(_x > 4) then {breakOut "loop1"};
hint "NOOOOOOOOOOOO";
};
while{true} do {
scopeName "loop2";
_x = _x - 1;
hint format["%1", _x];
sleep 1;
if(_x < 1) then {breakOut "loop2"};
hint "NOOOOOOOOOOOOOOOOOOOO";
};
breakOut "main";
};
hint "YEEEEEEEEEEEEEES";

[wiggum2 31]

Sorry, but look at the example from the BIKI:

scopeName "main"; 
while {true} do {
scopeName "loop1"; 
while {true} do {
[...]

So the "scopeName" always after the while or before ?

[nuxil 2]

i think you missunderstand what scopes are.

you might rather say. scope names is always after { but not entierly true

scopename "a";
if (tralla) then
{
   scopename "b";
   if (something) then
   {
       scopename "c";
       if (ok) then
       {
           code;
       };
       // this is scope c
   };
   //this is scope b
};
//scope a

i dont know if i can explain it better than this.

you can not define a name for a scope twise in same scope.

Edited October 22, 2011 by nuxil

[wiggum2 31]

Ok, but what not works is this:

scopename "a";
while {tralla} do
{
   scopename "b";
   while {something} do
   {
           code;
   };
   //this is scope b
       scopename "c";
       while {ok} do
       {
           code;
       };
       // this is scope c
};
//scope a  

But why ?

I think a scope is jus everything after "scopeName" while/if {}

Edited October 22, 2011 by Wiggum

If you format your script you will see that you have two scopeName`s in one While-loop!

private ["_x"];
_x = 0;
scopeName "main";
[color="Red"]while{true} do {[/color]
  [color="Red"]scopeName "loop1";[/color]
     while{true} do {
     _x = _x + 1;
     hint format["%1", _x];
     sleep 1;
     if(_x == 5) then {breakTo "loop1"};
     hint "NOOOOOOOOOOOO";
     };
  [color="Red"]scopeName "loop2";[/color]
     while{true} do {
     _x = _x - 1;
     hint format["%1", _x];
     sleep 1;
     if(_x == 0) then {breakTo "loop2"};
     hint "NOOOOOOOOOOOOOOOOOOOO";
     };
[color="Red"]};[/color]
hint "YEEEEEEEEEEEEEES";  

:coop:

[wiggum2 31]

This looks like two sub-scopes inside one main-scope (while) to me:

[color="Red"]scopeName "main";
while {true} do {[/color]
[color="SeaGreen"]scopeName "loop1"; 
while {true} do { [/color]
[color="Blue"]scopeName "loop2"; 
if (condition1) then {
breakTo "main"
};
if (condition2) then {
breakOut "loop2"
}; [/color]
[color="SeaGreen"]}; [/color]
[color="Red"]};[/color]

@ Buliwyf

I think you added the color a bit wrong.

Again,why does it not work ?

Why have (look a my example below) i named the same scope twice now ?

Only one sub-scopename per while loop ?

private ["_x"];
_x = 0;
[color="Red"]scopeName "main";
while{true} do {[/color]
  [color="SeaGreen"]scopeName "loop1";
     while{true} do {[/color]
     _x = _x + 1;
     hint format["%1", _x];
     sleep 1;
     if(_x == 5) then {breakTo "loop1"};
     hint "NOOOOOOOOOOOO";
     [color="SeaGreen"]};[/color]
  [color="Blue"]scopeName "loop2";
     while{true} do {[/color]
     _x = _x - 1;
     hint format["%1", _x];
     sleep 1;
     if(_x == 0) then {breakTo "loop2"};
     hint "NOOOOOOOOOOOOOOOOOOOO";
     [color="Blue"]};[/color]
[color="Red"]};[/color]
hint "YEEEEEEEEEEEEEES";

It seems impossible to add more then one while sub-scopes to a main scope (while loop)...

With a if scope this works, look at the example above.

:rolleyes:

not sure what you mean? but as i said. you can only name a scope once.

scopename "a"
while {true} do 
{
   scopename "b";
   while {true} do
   {
       scopename "c";
       while {true} do 
       {
           scopename "d";
           ...
       };
   };
};

[wiggum2 31]

Yes, i understand.

But look at my example, its just the same like you just posted isnt it ?

private ["_x"];
_x = 0;
[color="Red"]scopeName "main";
while{true} do {[/color]
  [color="SeaGreen"]scopeName "loop1";
     while{true} do {[/color]
     _x = _x + 1;
     hint format["%1", _x];
     sleep 1;
     if(_x == 5) then {breakTo "loop1"};
     hint "NOOOOOOOOOOOO";
     [color="SeaGreen"]};[/color]
  [color="Blue"]scopeName "loop2";
     while{true} do {[/color]
     _x = _x - 1;
     hint format["%1", _x];
     sleep 1;
     if(_x == 0) then {breakTo "loop2"};
     hint "NOOOOOOOOOOOOOOOOOOOO";
     [color="Blue"]};[/color]
[color="Red"]};[/color]
hint "YEEEEEEEEEEEEEES";

[color="Red"]scopename "a"
while {true} do 
{[/color]
[color="SeaGreen"]    scopename "b";
   while {true} do
   {[/color]
[color="Blue"]        scopename "c";
       while {true} do 
       {[/color]

       [color="Blue"]};[/color]
   [color="SeaGreen"]};[/color]
[color="Red"]};[/color] 

Have you tried this ingame ?

EDIT:

Now i spotted my error..pretty clear now if i look at it !

But two seperate while loops (with scopeName) inside another while loop (main scope) should be possible i think...

follow the closing of the brackets, that tells you where scopes begin and end, if your script is formatted, every new tab indicates a new scope, so that means, that two scopes within the same tab of space, is wrong, because its the same scope. which is why:

while {true} do {
  scopename "one";
  blah.....
  if (blah) then {
  };
  scopename "two";
};

throws an error, because the inside of that while loop (scope 1) is trying to be renamed to a different scope, that would only work and not error, if you moved scopename two inside the if statement, as that is a new tab of space, and a new scope.
