Returns an array of game objects seen within the given area that passes the optional filter which can be one of a player index, ALL_PLAYERS, ALLIES or ENEMIES. By default, filter is ALL_PLAYERS. Finally an optional parameter can specify whether only visible objects should be returned; by default only visible objects are returned. The label can either be actual positions or a label to an AREA. Calling this function is much faster than iterating over all game objects using other enum functions. (3.2+ only)
