Documentation

FIFO Match

- addPlayer(object, notify) takes in an object to store in a queue as the first argument. In the second argument, notify will be fired when the list reaches capacity of two or more elements and first objects put into the queue are removed until the size is less than 2.

Elo Based Match

Note: notify is automatically called once a match is found.

- addPlayer(object) takes in an object to store in a queue as the first argument. Object must contain "elo" property which is a number.
- setNotify(notify) sets the notify function to be used.
- setRequiredEloDistance(newRequiredEloDistance) sets the threshold where a match is considered where newRequiredEloDistance is a number. Default is 1000.
- setRequiredDefaultTimeWeight(newRequiredDefaultTimeWeight) sets the weight of time when computing a match where newRequiredDefaultTimeWeight should be a number resembling a decimal percentage. Default is 0.15.
- setDefaultRefreshRate(newDefaultRefreshRate) sets the default refresh rate of the interval when checking for matches between players and newDefaultRefreshRate should be a number. Default is 1000ms.
- clearMatchMaking() sets the player queue to an empty array.
- stopMatchMaking() calls clearInterval on the running match making interval.
- startMatchMaking() calls startInterval(notify, defaultRefreshRate).
- stopAndClearMatchMaking()` calls stopMatchMaking() then clearMatchMaking().
