Using CloudScript actions with PlayStream

// This is a CloudScript function.
// "args" is set to the value of the "FunctionParameter" parameter of the ExecuteCloudScript API.
// "context" contains additional information when the CloudScript function is called from a PlayStream action.
handlers.helloWorld = function (args, context) {

    // The pre-defined "currentPlayerId" variable is initialized to the PlayFab ID of the player logged-in on the game client.
    // CloudScript handles authenticating the player automatically.
    var message = "Hello " + currentPlayerId + "!";

    // You can use the "log" object to write out debugging statements. It has
    // three functions corresponding to logging level: debug, info, and error. These functions
    // take a message string and an optional object.
    log.info(message);
    var inputValue = null;
    if (args != null && args != undefined)
    {
        inputValue = args.inputValue;
    }
    log.debug("helloWorld:", { input: inputValue });

    // The value you return from a CloudScript function is passed back
    // to the game client in the ExecuteCloudScript API response, along with any log statements
    // and additional diagnostic information, such as any errors returned by API calls or external HTTP
    // requests. They are also included in the optional player_executed_cloudscript PlayStream event
    // generated by the function execution.
