Trying viewing this Pen in Debug Mode, which is the preview area without any iframe and does not require JavaScript. Any URL's added here will be added as s in order, and before the CSS in the editor. The resource you are linking to is using the 'http' protocol, which may not work when the browser is using https. Obviously, the game is boring if the paddle can’t move. You can apply a script from anywhere on the web to your Pen. Functions are just little packages of code. You can fill in just one value in the background function between 0 (black) and 255 (white) to create a shade of grey. That’s what this code below does. Or, choose Neither and nothing will be applied. On that note, make sure that every function and if statement has both an opening curly brace { and a closing curly brace }. For more p5.js, I have also written an Instagram Filter tutorial and a Sunset Scene tutorial. The code in the ellipse function places the circle at the point (100, 100) and gives it both a width and height of 50 (making it a circle). Tags: #css #html #javascript Howdy Folks, in this new tutorial, you will learn how to create the classic Ping Pong Game with Javascript and HTML5 canvas. In CodePen, whatever you write in the HTML editor is what goes within the tags in a basic HTML5 template. By continuously updating the x- and y-coordinates of an object in the draw function, you can animate it. Now if we refresh, our canvas takes up the whole preview screen! Now we are prepared to animate our ball! Add these to the top of your code, along with the ball-associated variables: This allows us to alter the paddle’s x- and y-coordinates from anywhere in the code and prepares us to define a 100x25 paddle. If the preprocessor matches, it will attempt to combine them before processing. If you link to another Pen, it will include the CSS from that Pen. Make sure it occurs AFTER the if statement above! Player wins the game … At the very top of your code, before the setup function, create these variables: xBall starts off the ball with a random x-coordinate between 50 and 350. yBall starts off the ball with a default y-coordinate of 50. If you want to add classes there that can affect the whole document, this is the place to do it. You can see that xBallChange and yBallChange are multiplied by -1 to achieve this effect. Add this code to the bottom of your program, after the draw function ends: Now you should be able to control your paddle with the right and left arrow keys!
