Used in the game
There were a couple of usages of custom
data attributes
in the game with dif-
ferent purposes and for different reasons. As mentioned previously, one use was to
specify a player's current speed. Two other instances of the attribute were used to
identify and distinguish a player from the other and to group separate buttons that
were intended to behave the same way.
