Title: Using exitwith in sqf files
Post by: Gielovic on 10 Nov 2007, 16:40:38

Hey guys,

I have somthing like this in my sqf script

Code: [Select]

FUNCTION = {private[blabla];
while(true) do{somthing};
[b]???if(true) exitWith{}???[/b]
}; //end

[blabla] call FUNCTION;
[balbal] call FUNCTION;
:
:
[blkajd] call FUNCTION;

do i need to insert an exitwith in the end of the function ( like i did in bold ) to let it terminate or does it do that automatically?

You don't need to terminate a function in any way. The only thing is that the function will always return the value of the last statement in it so I tend to just put nil at the end so that I'm not returning something unexpected (which is the same as a final if (true) exitWith {}).

Code: (returns the new value of var, which may not be expected) [Select]

add5ToVar =
{
    var = var + 5;
};


Code: (returns nil) [Select]

add5ToVar =
{
    var = var + 5;
    nil;
};


Code: (returns nil) [Select]

add5ToVar =
{
    var = var + 5;
    if (true) exitWith {};
};
