I'm going through the HTML game module, and I found " var myleft = this.x; var myright = this.x + (this.width); var mytop = this.y; var mybottom = this.y + (this.height); " In https://www.w3schools.com/graphics/game_obstacles.asp Can someone please explain what points are myleft, myrightm mytop and mybottom on the component? I'm confused because aren't myleft and mytop the same point on the component? Please help. Thanks, Prakhar

I copied the game code from w3 schools for a school project, however I wanted to change the turning and moving object from a red square to an image. Now everything works fine but the image does not turn when the object turns, how do I fix this. Here is my code: <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1.0"/> <style> canvas { border:1px solid #d3d3d3; background-color: #f1f1f1; } </style> </head> <body onload="startGame()"> <script> var myGamePiece; function startGame() { myGamePiece = new component(30, 30, "images/smiley.png", 255, 255, "image"); myGameArea.start(); } var myGameArea = { canvas : document.createElement("canvas"), start : function() { this.canvas.width = 800; this.canvas.height = 500; this.context = this.canvas.getContext("2d"); document.body.insertBefore(this.canvas, document.body.childNodes[0]); this.frameNo = 0; this.interval = setInterval(updateGameArea, 10); window.addEventListener('keydown', function (e) { e.preventDefault(); myGameArea.keys = (myGameArea.keys || []); myGameArea.keys[e.keyCode] = (e.type == "keydown"); }) window.addEventListener('keyup', function (e) { myGameArea.keys[e.keyCode] = (e.type == "keydown"); }) }, stop : function() { clearInterval(this.interval); }, clear : function() { this.context.clearRect(0, 0, this.canvas.width, this.canvas.height); } } function component(width, height, color, x, y, type) { this.type = type; if (type == "image") { this.image = new Image(); this.image.src = color; } this.width = width; this.height = height; this.speed = 0; this.angle = 0; this.moveAngle = 0; this.x = x; this.y = y; this.update = function() { ctx = myGameArea.context; if (type == "image") { ctx.drawImage(this.image, this.x, this.y, this.width, this.height); } else { ctx.fillStyle = color; ctx.fillRect(this.width / -2, this.height / -2, this.width, this.height); } ctx.save(); ctx.translate(this.x, this.y); ctx.rotate(this.angle); ctx.restore(); } this.newPos = function() { this.angle += this.moveAngle * Math.PI / 180; this.x += this.speed * Math.sin(this.angle); this.y -= this.speed * Math.cos(this.angle); } } function updateGameArea() { myGameArea.clear(); myGamePiece.moveAngle = 0; myGamePiece.speed = 0; if (myGameArea.keys && myGameArea.keys[37]) {myGamePiece.moveAngle = -2; } if (myGameArea.keys && myGameArea.keys[39]) {myGamePiece.moveAngle = 2; } if (myGameArea.keys && myGameArea.keys[38]) {myGamePiece.speed= 2; } if (myGameArea.keys && myGameArea.keys[40]) {myGamePiece.speed= -2; } myGamePiece.newPos(); myGamePiece.update(); } </script> <p></p> </body> </html> I very appreciate the help!

I was thinking it would be nice for people to be easily be able to play other people's games they made (using languages such as JavaScript) without telling them to copy-paste your code. I'd like to play what other people made. As long as its it not a virus code. The only problem is, how would you do it? I have no idea.

This would be quite a simple issue for someone more experienced: (I have just begun with Jquery and Javascript)I have coded a really simple HTML, CSS, Jquery animation.. The ball <div> moves from side to side (Pretty Damn COOL!) BUT... I need to try and trigger the animation with scrolling, basically creating a 'Pong' game. From one side of the scren to the other. HOW do I do this? I have been trying to find a sollution online and can't. Please help, or I will find you and kill you. <!DOCTYPE html><html> <head> <title> Pong </title> <style type="text/css"> .pong{ position: relative; border-radius:100%; top:250px; float:left; z-index: 1; width: 100px; height: 100px; transition-property: transform, -webkit-transform; transition-duration: 0.2s; transition-timing-function: ease-out; background-color:#FFF700; } #stage{ min-height:500px; min-width:500px; background-size:cover; } </style> <script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.js"></script> <script type="text/javascript"> $(document).ready(function () { move(); }); function move() { $(".pong").animate({ left: 900 }, { duration: 5000, complete: function () { $(".pong").animate({ left: 40 }, { duration: 5000, complete: function () { move(); } }); } }); } </script> <script type="text/javascript"> </script> </head> <body> <div class id="stage"> <div class="pong"> </div> </div> </body></html> any help would be greatly appreciated.

I seem to have gotten in over my head with this project. I spent most of the day just typing out code, without the ability to debug it due to slow browser speed. When I got off work I started correcting my syntax errors, which didn't take very long. Unfortunately, I have spent many hours trying to resolve some sort of logic error in the game which is apparently a very serious one, as it prevents any of my sprites from appearing. The fillRect() function is showing up perfectly, but the drawImage() function is not. I will go ahead and post the whole game code, as it is pretty concise by my own meager standards. I am a noob to javascript and coding in general, and this will probably show. That being said, I really expected this to work, and would certainly appreciate any help which is on offer. Upon previewing my post I noticed that spacing differences rendered my map array unreadable. I have decided to attach a text file (as I am not permitted to upload .js files) instead of pasting. I hope this is acceptable. script.txt -
Hi! I am making a little game for iOS using apache's Cordova.I use Zepto.js as a light css3 jQuery replacement for animations etc. Players have to create letters as Wim Crouwel did in his New Alphabet, they have to do it in a short amount of time, thus far the project is going fine for the limited skills i have but now i am encountering a problem and i dont know where it could come from. What happens is that when i validate if a letter hase been constructed correctly and it is in fact correct it adds 2 "levels" instead of just 1, what i discovered is that the script actually runs twice. It even reacts tot the amounts of clicks i made on the page, lets say i click 4 "clickable" element's on the page it ads 4 levels. This is what i get in the console: 2 clicks = 2 levels up?validating...correct! go from level 0 to..1validating...correct! go from level 0 to..2 here is a live demo:http://bram-de-leeuw...welGame/(you'll probably have to resize your browser to make it work, the first thing you'll see is a iPhone5 version that isn't styled correctly. When you'll make your browser smaller it will show a iPhone 4 version.) This is the validation code: // Validate Letter A$("#verder").click(function () {//if (Level = 0){ // LETTER = A // CORRECT console.log("validating..."); if ( // LETTER A $(".CenterBottom").hasClass("black") === true && $(".CenterRight").hasClass("black") === true && // NOT LETTER A $(".CenterLeft").hasClass("black") === false && $(".CenterTop").hasClass("black") === false && // ETC.. ){ // IF ITS CORRECT console.log("correct! go from level 0 to..") Level++; $("#alert-fact").animate("Alert", {duration:2000, easing: 'ease'}); $(".CenterBottom").animate("Correct", {duration:2000, easing: 'ease'}); $(".CenterRight").animate("Correct", {duration:2000, easing: 'ease'}); console.log(Level); // SOMETHING IS MISSING } else if ( $(".CenterBottom").hasClass("black") === true && $(".CenterRight").hasClass("black") === false || $(".CenterRight").hasClass("black") === true && $(".CenterBottom").hasClass("black") === false ) { $("#alert-missing").animate("Alert", {duration:2000, easing: 'ease'}); if ($(".CenterBottom").hasClass("black") === true) { $(".CenterBottom").animate("Correct", {duration:2000, easing: 'ease'}); }; if ($(".CenterRight").hasClass("black") === true) { $(".CenterRight").animate("Correct", {duration:2000, easing: 'ease'}); }; // WRONG } else { $("#alert-wrong").animate("Alert", {duration:2000, easing: 'ease'}); };//};//if (Level = 1){ // LETTER = B//};});
