Further Adventures

Listing 5.13 - Displaying a player's information - Task 1

Create a function called showLine that logs a line of dashes to the console.

var showPlayerInfo;
var showPlayerName;
var showPlayerHealth;
var showPlayerPlace;
var showLine;    // Declare a variable

showPlayerName = function (playerName) {
    console.log(playerName);
};

showPlayerHealth = function (playerName, playerHealth) {
    console.log(playerName + " has health " + playerHealth);
};

showPlayerPlace = function (playerName, playerPlace) {
    console.log(playerName + " is in " + playerPlace);
};

// Define the function and assign it
showLine = function () {
    console.log("----------------------------");
};

showPlayerInfo = function (playerName, playerPlace, playerHealth) {
    console.log("");

    showPlayerName(playerName);

    console.log("----------------------------");

    showPlayerPlace(playerName, playerPlace);
    showPlayerHealth(playerName, playerHealth);

    console.log("----------------------------");
    console.log("");
};

showPlayerInfo("Kandra", "The Dungeon of Doom", 50);
showPlayerInfo("Dax", "The Old Library", 40);

Listing 5.13 - Displaying a player's information - Task 2

Update the showPlayerInfo function to use the showLine function rather than logging dashes to the console directly.

var showPlayerInfo;
var showPlayerName;
var showPlayerHealth;
var showPlayerPlace;
var showLine;

showPlayerName = function (playerName) {
    console.log(playerName);
};

showPlayerHealth = function (playerName, playerHealth) {
    console.log(playerName + " has health " + playerHealth);
};

showPlayerPlace = function (playerName, playerPlace) {
    console.log(playerName + " is in " + playerPlace);
};

showLine = function () {
    console.log("----------------------------");
};

showPlayerInfo = function (playerName, playerPlace, playerHealth) {
    console.log("");

    showPlayerName(playerName);

    showLine();

    showPlayerPlace(playerName, playerPlace);
    showPlayerHealth(playerName, playerHealth);

    showLine();
    console.log("");
};

showPlayerInfo("Kandra", "The Dungeon of Doom", 50);
showPlayerInfo("Dax", "The Old Library", 40);

Listing 5.13 - Displaying a player's information - Task 3

Create and use a showBlankLine function for logging a blank line to the console.

var showPlayerInfo;
var showPlayerName;
var showPlayerHealth;
var showPlayerPlace;
var showLine;
var showBlankLine;    // Declare a variable

showPlayerName = function (playerName) {
    console.log(playerName);
};

showPlayerHealth = function (playerName, playerHealth) {
    console.log(playerName + " has health " + playerHealth);
};

showPlayerPlace = function (playerName, playerPlace) {
    console.log(playerName + " is in " + playerPlace);
};

showLine = function () {
    console.log("----------------------------");
};

// Define a function and assign it
showBlankLine = function () {
    console.log("");
};

showPlayerInfo = function (playerName, playerPlace, playerHealth) {
    showBlankLine();

    showPlayerName(playerName);

    showLine();

    showPlayerPlace(playerName, playerPlace);
    showPlayerHealth(playerName, playerHealth);

    showLine();
    showBlankLine();
};

showPlayerInfo("Kandra", "The Dungeon of Doom", 50);
showPlayerInfo("Dax", "The Old Library", 40);
