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.

Description

Description:
Suspends code 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.
ⓘ
  • this command will suspend the code for at least the given amount of time, and can be way more if the script scheduler is busy.
  • this command will suspend the script as the game gets paused in single player (and will resume with it). To avoid this, use uiSleep.
Groups:
Program Flow

Syntax

Syntax:
sleep delay
Parameters:
delay: Number - in seconds. Negative values will not be considered.
Return Value:
Nothing

Examples

Example 1:
[] spawn { sleep 5; hint "after (at least) 5 seconds..."; };
Example 2:
sleep 5 + random 10; // incorrect - will only sleep for 5 seconds, as it will be interpreted as (sleep 5) (+(random 10)) sleep (5 + random 10); // correct

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".
