JASS:
library GameStatus initializer Ini /*
GameStatus 3.1 by Bribe, special thanks to Troll-Brain
Check if a game is online, a replay or is a single-player game.
function GetGameStatus
takes nothing
returns integer
Get the status of the game. This function cannot be called until the
OnGameStatusFound function has run (so don't use this check during an
initialization or 0-second timer, wait for this function).
It returns one of the three constants:
GAME_STATUS_OFFLINE
GAME_STATUS_ONLINE
GAME_STATUS_REPLAY
function OnGameStatusFound
takes code func
returns nothing
Executes the function when the game's status has been detected.
Example use:
OnGameStatusFound(function OnLoad)
You are not able to use TriggerSleepAction from this function.
