Description
- Description:
- If the result of condition is true, code is evaluated, and current block with result of code. It only exits the current scope. exitWith exits the execution of a loop defined by one of commands do, for, count or forEach. When you use exitWith not inside a loops, the behaviour is undefined - sometimes it may exit the script, sometimes some other scope, but this is not intended and designed behaviour of this command, and it is not guaranteed to work reliably. It exits the loop only, not the script.

Syntax
Examples
- Example 1:
if (_x>5) exitWith {echo "_x is too big"; _x}
When _x is greater than 5, outputs message and terminates code in current level with value of _x- Example 2:
for "_j" from 1 to 10 do { player sideChat format ["%1",_j]; if (_j==5) exitWith {player sideChat "5 is enough"}; }; player sideChat "Complete";
Only the "for" loop will exit when the exitWith condition has been fulfilled (not the whole script). Execution will continue after the end of the loop (player sideChat "Complete").- Example 3:
- Most loops will also terminate when their scope exited. To exit and terminate scopes which are called every frame such as onEachFrame and waitUntil use the following examples:
onEachFrame { if (!alive player) exitWith { onEachFrame {} } }
_time = time + 10; waitUntil { if (time > _time) exitWith { true } }

- Since ArmA2 uses Blocks in FSM as any ordinary Handle like while, for etc. in Scripts, ExitWith also only closes the Block in the FSM.

- I cannot dare to edit the description of this command as it was put by BIS dev himself. But I'd like to clarify the nature of this command to avoid any further confusion. The command will exit the current scope - no ifs no buts. If the current scope is a loop, it will exit the loop. If the current scope is the main body of a script, it will exit the script. For more understanding of scopes and exitWith have a look at this resource.

- To further explain Killzone_Kid's above statement, exitWith does not work as described within any subsequent inner scopes of a loop - it will only simply exit the current scope. For example, this code will not exit the while loop:
while {true} do { // 'while' scope if (player == (leader player)) then { // 'if-then' scope if (time > (5 * 60)) exitWith {}; // This will only exit the 'if-then' scope }; sleep 1; }; hint "Mission Started"; // This code will never execute

- Do not use this command to exit the main body of a script. While the current implementation may do that, as Killzone_Kid said, it's not part of its specification and may change in the future which will break any scripts that depend on that behavior. That is what the developer was saying in the article.
