The ZIP package contains the game with 1920x1920 resolution that scales to fit the whole screen both in portrait and landscape mode
Just warning that for very wide screens, the game may not be perfectly full screen. The game is fully compatible with all most common mobile devices.
Sounds are enabled for mobile but we can't grant full audio compatibility on all mobile devices due to some well-know issue between some mobile-browser and HTML5. So if you want to avoid sound loading, please read Disable Sound section).
WARNING: Sounds can't be enabled for Windows Phone as this kind of device have unsolved issues with 'audio' and 'video' tag.

C)Getting Started - top

To install the game just upload on your server the game folder live_demo.

• Game Resize: All game resolution automatically center itself and fits on the screen thanks to the ctl_utils.js file. If you want to avoid this, comment this function in index.html file:

					$(document).ready(function(){
						if (isIOS()) {
							setTimeout(function () {
								sizeHandler();
							}, 200);
						} else {
							sizeHandler();
						}
					});
				

• Localization: You can easily change game text for different languages, changing string in CLang.js

					var TEXT_SCORE = "SCORE";
					var TEXT_SCORE_GAMEOVER = "TOTAL SCORE";
					var TEXT_LEVEL = "LEVEL";
					var TEXT_GAMEOVER = "GAME OVER";
					var TEXT_HOW_TO_PLAY = "HOW TO PLAY";
					var TEXT_PAUSE = "Pause";
					var TEXT_ARE_SURE = "ARE YOU SURE?";
					var TEXT_CREDITS_DEVELOPED = "DEVELOPED BY";
					var TEXT_NEXT = "NEXT";
					var TEXT_LINES = "LINES";
					var TEXT_PAUSE = "PAUSE";

					var TEXT_SHARE_IMAGE = "200x200.jpg";
					var TEXT_SHARE_TITLE = "Congratulations!";
					var TEXT_SHARE_MSG1 = "You collected ";
					var TEXT_SHARE_MSG2 = " points!

Share your score with your friends!";
					var TEXT_SHARE_SHARE1 = "My score is ";
					var TEXT_SHARE_SHARE2 = " points! Can you do better";

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 7 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({
                    level_up_lines: 10, //EVERY N LINES IS FILL 
                    score_line: [40, 100, 300, 1200], //ADD THIS VALUE TO SCORE WHEN DESTROY LINES
                    blocks_occurence: [19, 19, 19, 12, 12, 7, 11], //BLOCKS SPAWN OCCURENCE 
                    start_refresh_game: 1,
                    min_refresh_game: 0.05, //MINIUM REFRESH FOR GAME UPDATE (MAX VELOCITY OF GAME)
                    step_decrease_refresh_game: 0.25, //EVERY LEVEL UP REFRESH VALUE IS DECREASE 
                    audio_enable_on_startup:false, //ENABLE/DISABLE AUDIO WHEN GAME STARTS 
                    fullscreen:true,        //SET THIS TO FALSE IF YOU DON'T WANT TO SHOW FULLSCREEN BUTTON
                    check_orientation:false, //SET TO FALSE IF YOU DON'T WANT TO SHOW ORIENTATION ALERT ON MOBILE DEVICES
                    num_levels_for_ads: 3 //NUMBER OF TURNS PLAYED BEFORE AD SHOWING //
                            //////// THIS FEATURE  IS ACTIVATED ONLY WITH CTL ARCADE PLUGIN./////////////////////////// 
                            /////////////////// YOU CAN GET IT AT: ///////////////////////////////////////////////////////// 
                            // http://codecanyon.net/item/ctl-arcade-wordpress-plugin/13856421///////////
                });

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
   • CAreYouSurePanel: this class show are you sure panel.
   • CBlock: this class manage the block of cell.
   • CCell: this class manage a cell.
   • CController: this class show controller for mobile.
   • CCreditsPanel: this class show credits panel.
   • CEdges: this class manages sides edges.

   • CNextBlock: this class show next block.
   • CNextBlockBoard: this class show next block board.
   • CPause: this class show pause menu.
   • CSantaClaus: this class manages Santa Claus character.
   • CScoreBoard: this class show score board.
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 start the game
5. If the user click on the exit button in the up-right corner, the game returns to the menu screen
