• Event Touch Leave : This is an event by actor, which means it gets executed
when the actor holding it in its graph gets a touch moved over it and left while
click events are enabled.
• Write Leaderboard Integer : This allows you to write a leaderboard integer
value for a state name and submit it. It requires a player controller (which is the
current class used by the player to control and navigate), a state name (which is a
representation of the leaderboard value on the game center), and the value of this
state. This returns just one value: either true or false indicating the successful
or otherwise completion of the process.
• Read Leaderboard Integer : This queries for the value of an integer ( Stat
Name ). This function requires two inputs: the stat name and the player controller.
It can succeed and return the integer value to you as a Leaderboard Value , or it
can fail for some reason, such as no connection to the Internet.
• Flush Leaderboards : As its name implies, this flushes the leaderboard values in-
to the database. This requires the player controller as the input, as all other online
services do, and the session name which is the same as State Name too.
