Description

Description:

Suspend execution of function or SQF based script until condition is satisfied. This command will loop and call the code inside {} every frame until the code returns true. The execution of the rest of the script therefore will be suspended until waitUntil condition is satisfied and the loop is aborted. Because of this script suspension use spawn or execVM to safely execute code containing waitUntil.

In case you have more complex code inside waitUntil loop, to be on the safe side always return boolean at the end of the scope: player addEventHandler ["Fired", { _null = (_this select 6) spawn { _p = [0,0,0]; waitUntil { if (isNull _this) exitWith {true}; _p = getPos _this; false //<-- boolean at the end of the scope }; hint str _p; }; }];

waitUntil suspends both SQF functions and SQF scripts. In functions, the calling script is still in suspension due to waiting for a return from the call command. The game engine will continue, however. See Function for more detail.

If WaitUntil uses an undefined call code, WaitUntil won't release, even when this code is separated from other conditions through or. Be warned that this won't cause an error message.

By default the cycle time for the condition check is per frame. Look at the example 3, how to set it at a lower rate yourself. Often times one does not need per frame checking. Saves a lot CPU checks; especially when the condition is complex to compute.
