Flappy Bird Clone Coding

Flappy Bird is a game that is very addicting, and is a good idea to try to code, so I started to make it off a tutorial.

Game from tutorial

It is made with the phaser HTML5 game framework, which is very useful, it has things like velocity and handles sprites.


Code:

var mainState = { preload: function () { // This function will be executed at the beginning // Change the background color of the game game.state.backgroundColor = ‘#71c5cf’; // Load the bird sprite game.load.image(‘bird’, ‘assets/bird.png’); // That’s where we load the game’s assets }, create: function(){ // This function is called after the preload function // Set the physics system game.physics.startSystem(Phaser.Physics.ARCADE); // Display the bird on the screen this.bird = this.game.add.sprite(100, 245, ‘bird’); // Add gravity to the bird to make it fall game.physics.arcade.enable(this.bird); this.bird.body.gravity.y = 1000; // Call the ‘jump’ fnction when the space key is hit var spaceKey = this.game.input.keyboard.addKey(Phaser.Keyboard.SPACEBAR); spaceKey.onDown.add(this.jump, this); // Here we set up the game, display sprites, etc. }, update: function() { // This function is called 60 times per second // If the bird is out of the world (too high or too low), call the ‘restartGame’ function if (this.bird.inWorld == false) this.restartGame(); // It contains the game’s logic }, jump: function() { // Add a vertical velocity to the bird this.bird.body.velocity.y = -350; },

It doesn’t have the traditional bird or pipe they use in the real game like so:

Instead it uses colored squares, orange for the player, and green for the pipes.

Sprites in the game asset files.

It is a good tutorial to learn for those who want to develop games, and it helps us understand how the games are built.
