Why function quickJoinGame in GameApi fire Exception, when I try call it on empty server zone? In my opinion if the zone does not have any room it should return null and not exception.

Code: Select all

findRoomsMathExpression = new MatchExpression(RoomProperties.IS_GAME, BoolMatch.EQUALS, true).and
                                           (RoomProperties.HAS_FREE_PLAYER_SLOTS, BoolMatch.EQUALS, true);

 getGameApi().quickJoinGame(user, findRoomsMathExpression, getZone(), "battle");

Code: Select all

The API expect at least one Room to search, otherwise it doesn't make sense searching for anything. If you don't want to catch the exception (which is actually a RuntimeException, so not mandatory) you could just make a little check.

Code: Select all

if (zone.getRoomCount() == 0) 
// avoid searching...

which is the same as testing if the returned Room is null.

This IF should be inside a function quickJoinGame, that function does not fall under the correct parameters. I handed her a MatchExpression and search location(Zone), it should not fall if it did not find any room. Otherwise it seems unreliable.
