D)HTML Structure - top

This game have the canvas tag in the body. The ready event into the body calls the main function of the game: CMain().
The head section declares all the javascript functions of the game. The whole project uses a typical object-oriented approach.
In the init function there are 8 mapped events that can be useful eventually for stats


  • Game option: You can easily customize game setting when creating a new instance of the game in index.html file
  • 					var oMain = new CMain({
    											audio_enable_on_startup:false, //ENABLE/DISABLE AUDIO WHEN GAME STARTS 
    											check_orientation: true,     //SET TO FALSE IF YOU DON'T WANT TO SHOW ORIENTATION ALERT ON MOBILE DEVICES
    															[[100, 0, 0, 0],
    															 [80, 20, 0,0],
    															 [75, 15, 5, 5],
    															 [10, 10, 80, 0],
    															 [50, 35, 0, 15],
    															 [45, 35, 0, 20],
    															 [0, 0, 70, 30],
    															 [25, 45, 0, 30],
    															 [0, 60, 10, 30],
    															 [0, 0, 50, 50],
    															 [5, 35, 30, 30]
    											iPlayerHealth: 5, //SET HOW MANY HIT THE PLAYER CAN TAKE
    											aZombieHealth: [1, 2, 1, 3], // SET HOW MANY SHOT EACH ZOMBIE CAN TAKE
    											aAmountZombiesOnStage: [8, 18, 28, 39, 50, 62, 73, 84, 95, 95, 95], // SET THE NUMBER OF ZOMBIES FOR EACH WAVE, AFTER THE LAST ONE THE NUMBER IS FIXED
    											iWaveInterval : 1.5, //HOW MANY SECONDS WE WAIT BETWEEN WAVES
    											iSpawnInterval : 1, // HOW MANY SECONDS WE WAIT BETWEEN ZOMBIE SPAWNS
    											iZombieOnScreen : 4 //MAXIMUM NUMBER OF ZOMBIES VISIBLE ON SCREEN

    E) CSS Files and Structure - top

    The game use two CSS files. The first one is a generic reset file. Many browser interpret the default behavior of html elements differently. By using a general reset CSS file, we can work round this. Keep in mind, that these values might be overridden somewhere else in the file.

    The second file contains all of the specific stylings for the canvas and some hack to be fully compatible with all most popular mobile devices

    F) Source Code - top

    This game contains:

    1. jQuery
    2. Our custom scripts
    3. CreateJs plugin
    4. Howler Sound library
    1. jQuery is a Javascript library that greatly reduces the amount of code that you must write.
    2. The game have the following js files:
      • CMain: the main class called by the index file.
        This file controls the sprite_lib.js file that manages the sprite loading, the loop game and initialize the canvas with the CreateJs library
      • ctl_utils: this file manages the canvas resize and its centering
      • sprite_lib: this class loads all images declared in the main class
      • settings: general game settings
      • CLang: global string variables for language localization
      • CPreloader: simple text preloader to show resources loading progress
      • CMenu: simple menu with the play button
      • CGfxButton: this class create a standard button
      • CToggle: this class create a standard toggle button
      • CTextButton: this class create a standard text button
      • CGame: this class manages the game logic
      • CInterface: this class controls game GUI that contains text and buttons
      • CPlayer: this class manages all the info about the player such as ammo and health
      • CZombie: this class manages a single zombie.
      • CEndPanel: this class is a simple panel that show you score at the end of the game.
      • CHelpPanel: this class is a simple panel that show how to play.
      • CTweenController: this class manages the tweening function for zombie movement.
      • CCreditsPanel: this class is a simple panel that display info about the creator of the game.
    3. CreateJs is a suite of modular libraries and tools which work together to enable rich interactive content on open web technologies via HTML5.
    4. Howler is a javascript Audio library.

    Resuming, the complete game flow is the following:

    1. The index.html file calls the CMain.js file after ready event is called
    2. The main class calls CPreloader.js to init preloader text and start sprite loading
    3. When all sprites contained in "/sprites" and "/sounds" folder are loaded, the main class removes the preloader and calls the CMenu.js file that shows the main menu
    4. If the user click the Play button in main menu, the CGame.js class is called and game starts
    5. CGame.js creates than the stage, and instantiate the max possible CZombie.js class that is possible and call the main game loop using the Update() function
    6. In the main game loop are handled the camera bobbing, the background looping and the general game states ("Waiting For Wave", "In-game", "GameOver")
    7. Each CZombie.js class listen for the mouse or touch click on its sprite and then communicate with CGame.js its state
    8. If the user click on the exit button in the down-right corner, the game returns to the menu screen
