C)Getting Started - top

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

• Game Embedding: The proper way to embed the game is in a full-screen web page or in an iframe.
  In the first case the game will fit the screen size, in the second, that of the iframe.
  If the iframe size matches that of the screen, the game will fit accordingly.
  The alignment will be proportioned to the aspect ratio of the game.
  To install the game in a WordPress website, we suggest to use our plugin CTL Arcade .
  
  
• Localization: You can easily change game text for different languages, changing string in CLang.js

						TEXT_START_GAME = "CLICK ON THE SCREEN TO START THE GAME";

						TEXT_GAMEOVER  = "GAME OVER";
						TEXT_SCORE     = "YOUR SCORE IS: ";
						TEXT_PAUSE      = "PAUSE";
						var TEXT_DEVELOPED = "developed by";

						TEXT_DESKTOP = "MOVE YOUR MOUSE LEFT OR RIGHT TO CONTROL THE HERO. THE FURTHER THE CURSOR WILL BE FROM THE CENTRE OF THE SCREEN, THE FASTER THE HERO WILL FLY";
						TEXT_MOBILE = "SWIPE LEFT OR RIGHT TO CONTROL THE HERO. THE FURTHER YOUR FINGER WILL BE FROM THE CENTER OF THE SCREEN, THE FASTER THE HERO WILL FLY";
						TEXT_ORIENTATION = "TURN YOUR PHONE LEFT OR RIGHT TO CONTROL THE HERO. THE MORE YOU'LL ROTATE THE PHONE, THE FASTER THE HERO WILL FLY";

						TEXT_PLATFORM0 = "FIXED PLATFORM";
						TEXT_PLATFORM1 = "MOVING PLATFORM";
						TEXT_PLATFORM2 = "CRASHING PLATFOMR";
						TEXT_PLATFORM3 = "VANISHING PLATFORM";

						TEXT_SPRING = "MEGA JUMP PLATFORM";

						TEXT_COIN = "EXTRA SCORE COINS";
						TEXT_WINGS = "SUPER SPEED POWERUP";

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

Share your score with your friends!";
						TEXT_SHARE_SHARE1 = "My score is ";
						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 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({
											player_spd_max: 15,                      //maximum speed that the player can reach
                                            player_spd_min: 0.2,                     //minimum speed that the player can reach
                                            player_acceleration_no_giroscope: 1.2,   //the accelleration to moltiply to the velocity to the player when there is no giroscope on device
                                            player_acceleration_giroscope: 1.1,      //the accelleration to moltiply to the velocity to the player when there is the giroscope on device
                                            player_deceleration: 0.9,                //deceleration to add to the player in way to reache the player_spd_min
                                            object_spd: 5,                           //speed of the object (when they are going to move vertically)
                                            object_spd_orizzontal: 4,                //speed of the object (when they are going to move orizontally)
                                            acceleration: 4,                         //acceleration of the various objects ( platforms, coins, ... )
                                            deceleration: 0.8,                       //deceleration of the various objects ( platforms, coins, ... )
                                            deceleration_bg_game_over: 0.5,          //deceleration of the game background when there is a game over
                                            object_spd_max: 17,                      //maximum speed that the varios object can reach
                                            object_spd_min: -17,                     //minimum speed that the varios object can reach
                                            gamma_range_accepted: 4,                 //maxinum gamma read from the game, the more it is, the more the game is difficult (if there is a giroscope)
                                            canvas_half_width_range_accepted: 215,   //cursor range accepted (calculated by the half measure of the canvas width +- this value), if there is no giroscope
                                            num_platform_created_for_spring: 20,     //number of platform to create before the game decide if it have or not to spawn a spring
                                            height_between_object: [50, 60, 70, 80], //distance from a platform to another
                                            coin_occurrence: 100,                     //occurrence percentage of the coin. Set this between 0-100.
                                            bonus_occurrence:1,                       //occurrence percentage of the 'Super Jump' power-up. Set this between 0-100.

                                            check_orientation:true //SET TO FALSE IF YOU DON'T WANT TO SHOW ORIENTATION ALERT ON MOBILE DEVICES
                                           });

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

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
   • CVector2: this class manages the calculations between 2 vectors
   • CMath: this class manages the calculations
   • 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
   • CHelp: this class shows the Help Panel
   • CInterface: this class controls game GUI that contains text and buttons
   • CEndPanel: this class controls game GUI that contains text and buttons
   • CPlayer: this class manages what the player have to do
   • CPlatform: this class manages what the platform have to do
   • CSpring: this class manages what the spring have to do
   • CBonus: this class manages what the bonus ( coin, super jump power up) have to do
   • CScrollingBG: this class controls the scrolling of the 4 backgrounds
   • CClouds: this class manages the clouds over the background after a certain score
3. CreateJs is a suite of modular libraries and tools which work together to enable rich interactive content on open web technologies via HTML5.

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 CHelp.js class is called, then, after this, the CGame.js Class is called and game starts
5. If the user click on the exit button in the down-right corner, the game returns to the menu screen
