Description

Description:

Suspend execution for given time in seconds. The sleep precision is given by a framerate, the delay given is the minimal delay expected. Must be called inside of a context which is interruptible, i.e. a script executed by execVM or spawn.

Note that this command will suspend the script indefinitely if game simulation is paused in SP. To avoid this, use uiSleep.

Sleep 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.

Sleep durations between .0005 and .02 will cause the same delay (roughly .02 seconds).
Delays of .0005 and less have no effect (ie, the sleep call will return immediately).

Sbsmac

The comment above is a little misleading. The game engine appears to work by processing frames and then checking to see whether scripts are available to execute. Sleep causes the script/function to be suspended until at least the specified time has elapsed. To wait for the next frame, or give other scripts a chance to run, use Sleep 0.001.

For scripts called by the Init Event Handler the first sleep command will suspend the script at the briefing screen at the start of a mission. The script will continue after the briefing screen, when actually "in game".

Sleep will treat negative values as if they were 0. (Tested in Arma 3 v1.22)

For server scripts, if you are creating "while true" timers, it is best to use uiSleep instead, as the sleep from that command is not slowed down by simulation / server lag, so the timers will execute at intervals that are much closer to real time, even under heavy lag.

Waffle SS.

The sleep command will be ignored on JIP. This affects code/functions called from init.sqf or object initialization. It will simply ignore the command and continue through the code. Even if the function uses spawn to create a new process.
