Resize external website to fit in the iFrame

NG Code, How to, Quick Tip, Useful

I recently had to publish a game on my website which was written by another developer and was in public domain. My website was responsive and worked great for PC, tablet and mobile but this game came in a fixed size and was not responsive. It was using canvas which could not be resized inside an iFrame to fit in the available space so I looked for options to fit this game in my website layout and make it work for all devices (PC, tablet, mobile). The idea was to use something which would work similar to how mobile devices use viewport to fit the content in its browser. CSS3 comes with the support for scaling of iFrame content which works perfectly in my scenario so the embeded game/page is scaled down to fit in the iFrame. There is some computation required to scale the embeded page correctly. The article[…]

Add Phaser 2 style buttons in Phaser 3

NG How to, JavaScript, Phaser, Quick Tip

Phaser 2 had a very convenient way of adding buttons to a state. Phaser 3 has got rid of those buttons but if we want to keep the habit of adding buttons in Phaser 3 scenes like we used to in Phaser 2, following lines will help achieve it. Phaser.Scene.prototype.addButton = function (x, y, key, callback, callbackContext, overFrame, outFrame, downFrame) { // add a button let btn = this.add.sprite(x, y, key, outFrame).setInteractive(); btn.on(‘pointerover’, function (ptr, x, y) { this.setFrame(overFrame); }); btn.on(‘pointerout’, function (ptr) { this.setFrame(outFrame); }); btn.on(‘pointerdown’, function (ptr) { this.setFrame(downFrame); }); btn.on(‘pointerup’, callback.bind(callbackContext, btn)); return btn; }; Above piece of code can now be used var button = this.addButton(100, 100, ‘buttons’, this.clickButton, this, overFrame, outFrame, downFrame); clickButton event can be defined as following clickButton(button) { // use this to access scene // button is also available as the first param }

Use textarea in Phaser Game

NG How to, HTML5, JavaScript, Phaser, Quick Tip

In order to use textboxes in canvas we can use html input components and position them over the canvas. I recently had a requirement to display a message board resembling “textarea” in a Phaser game. The game was responsive so it also required repositioning and resizing of the textarea. I am posting bare minimum code to achieve this fuctionality here. Add following html <!DOCTYPE html> <html> <head> <title>Demo</title> <meta http-equiv=”Content-type” content=”text/html; charset=utf-8″> <meta name=”viewport” content=”width=device-width, minimum-scale=1, initial-scale=1, user-scalable=no”> <link rel=”stylesheet” href=”css/app.css”> <script src=”js/phaser.min.js”></script> <script src=”js/game.js”></script> </head> <body> <textarea disabled id=”txtArea” style=”display:none” class=”txtArea”></textarea> <div id=”container”> <div id=”mygame”></div> </div> </body> </html> We have added a textarea which is hidden initially. We will display this component after resizing and repositioning inside the game. Now add css as following in app.css body { padding: 0px; margin: 0px; background: #862C2C; overflow-x: hidden; } .txtArea{ position: absolute; background-color: #ffffff; color: #000; padding: 10px; border: 3px solid #9E9E9E;[…]
