API JoinBattlefield

Queues the player, or the player's group, for a battlefield instance. JoinBattlefield(index[, asGroup[, isRated]])

Arguments

 * index : Number - Which battlefield instance to queue for (0 for first available), or which arena bracket to queue for.
 * asGroup : Boolean - If true-equivalent, the player's group is queued for the battlefield, otherwise, only the player is queued.
 * isRated : Boolean - If true-equivalent, and queueing for an arena bracket, the group is queued for a rated match as opposed to a skirmish.

Details
The function requests the player to be added to a queue for a particular instance of the currently selected battleground type, as set by (index). You CANNOT queue immediately after a call, and must instead capture the event that indicates that the instance list is available.

Example
The following code creates a utility function, JoinBattlegroundType, which allows you to queue for the first available instance of a specific battleground type. do local f, aG, iR = CreateFrame("FRAME"); f:SetScript("OnEvent", function(self, event)  JoinBattlefield(0, aG, iR);   self:UnregisterEvent("PVPQUEUE_ANYWHERE_SHOW");  end); function JoinBattlegroundType(index, asGroup, isRated) if f:IsEventRegistered("PVPQUEUE_ANYWHERE_SHOW") then error("A join battleground request is already being processed"); end f:RegisterEvent("PVPQUEUE_ANYWHERE_SHOW"); aG, iR = asGroup, isRated; RequestBattlegroundInstanceInfo(index); end end
