Phaser tutorial: creation of an HTML5 string avoider prototype, working on mobile devices too

Read all posts about "" game

Last summer I showed you how to create an HTML5 String Avoider game made with Phaser, but at that time Phaser was 2.0.5 version while now we have 2.2 released with a lot of new features, and above all now it works on iOS browsers.

This is the game, move the mouse around the maze and don’t let the string touch the walls:

You can play directly on your mobile devices going to this link.

And this is the source code, already explained in the original post.

				var game = new Phaser.Game(320,480,Phaser.CANVAS,"",{
					preload:onPreload,
					create:onCreate,
					update:onUpdate
				});
				
				var tailLength=1;
				var tailNodes=300;
				var nodes = [];
				var canvas;
				var bitmap;
            		
				// THE GAME IS PRELOADING
				function onPreload() {
					game.scale.pageAlignHorizontally = true;
					game.scale.pageAlignVertically = true;
					game.scale.scaleMode = Phaser.ScaleManager.SHOW_ALL;
					game.scale.setScreenSize(true);
					game.load.image("maze", "maze.png");
					for (i=0; i<tailNodes; i++) {
	                		nodes[i]={
						 	x:0,
							y:0
						};
	            		};
				}
				
				// THE GAME HAS BEEN CREATED
				function onCreate() {
					bitmap = game.make.bitmapData(320,480);
					bitmap.draw("maze");
					bitmap.update();
					game.add.sprite(0,0,bitmap);
					canvas = game.add.graphics(0,0); 
				}
							
				// THE GAME IS GOING TO BE UPDATED
				function onUpdate() {
					canvas.clear();
					canvas.alpha=1;
					canvas.lineStyle(2,0x00ff00,1);
					var headX=game.input.x;
					var headY=game.input.y;
					canvas.moveTo(headX,headY);
					nodes[0]={
						x:headX,
						y:headY
					};
					for(var i=1;i<tailNodes-1;i++){
						var nodeAngle = Math.atan2(nodes[i].y-nodes[i-1].y,nodes[i].x-nodes[i-1].x);
						nodes[i]={
							x: nodes[i-1].x+tailLength*Math.cos(nodeAngle),
							y: nodes[i-1].y+tailLength*Math.sin(nodeAngle) 
						}
						
						var color = bitmap.getPixelRGB(Math.round(nodes[i].x),Math.round(nodes[i].y));
						if(color.a!=0){
							canvas.lineStyle(2,0xff0000,1)
						}
						canvas.lineTo(nodes[i].x,nodes[i].y);
					}
	    			}
	    		};
