Tutorial: Can participate

By default, all players will play all stages of an app. This behaviour can be customized by creating a Stage.canPlayerParticipate(player) function that returns true if the player should play the stage, or false otherwise.

Here is an example:

// app.js
myStage.canPlayerParticipate = function(player) {
    if (player.idInGroup == 1) {
        return true;
    } else {
        return false;
    }
}

In this example, only the first players of each group will play myStage. Other players will proceed directly to the next stage, without calling myStage.playerStart and myStage.playerEnd
