API:IsPlayerSolo

UI Lua API · Group functions
Version: WAR 1.4.8

Returns whether the player has no groupmates, as the number 1 or 0.

solo = IsPlayerSolo()

Arguments

None.

solo: number – 1 if the first groupmate slot is empty, otherwise 0. Nothing if there is no player object.

The result is a number, not a boolean. In Lua both 0 and 1 are true values, so if IsPlayerSolo() then is always taken. Compare with == 1, as the stock UI does.
Only the first groupmate slot is tested: the slot counts as empty when its stored level is 0.
Warband membership is not looked at separately.

None.

From default/ea_playerassist/source/ea_playerassist.lua:

local isPlayerSolo = ( IsPlayerSolo() == 1 )
