WebP Image Fallback Options

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

WebP is a relatively new image format which provides lossless and lossy compression for web images. It was developed and released by Google in 2010. Accroding to Google WebP format saves around 25-30% of image size which is a big saving for image-heavy sites. Even for normal sites, it saves a lot of network bandwidth and results in overall performance improvement of a web site (in turn a better ranking by search engines). Even though this format has been there since 2010, it is still not supported by all browsers.The good thing is that it is natively supported in Google Chrome and the Opera browsers which cover for bigger chunk of browser market share. For mobile sites this format has become a necessity to optimize load time of websites on mobile. Google provides tools to convert images from one format(png, jpg etc) to webp and viceversa https://developers.google.com/speed/webp/ If we are using webp format of[…]

Compile Cordova App for iOS

NG Cordova, How to, HTML5, iOS, Mobile

I recently planned to compile my Phaser games for iOS App Store. These games were build using Cordova CLI and have already been published on Android Store so I already have a functioning game which was to be ported to iOS. I decided to document the steps I had to follow to get my game compiled and published to iOS App Store. You can develop the game on any platform of your liking but in order to compile and publish these games to iOS App Store you do need to have a Mac. It can not be done from Windows or any other platform. Steps to compile the game: Download MacOS installer for Node.js and install it on your Mac. Go to App Store on your Mac and install latest version of XCode. You need XCode to build the game. Open Terminal console (Finder -> Applications ->Utilities) on your MacOS and install cordova using npm utility of Node.js by[…]

Phaser RESIZE Scale mode not resizing the game on mobile

NG Framework, HTML5, JavaScript, Mobile, Phaser

I had minimal html markup for a web game which used RESIZE scale mode as following <!DOCTYPE html> <html> <head> <meta charset=”utf-8″ /> <title>My Game</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> </head> <body> <div id=”game-container”> <div id=”mygame”></div> </div> <script src=”js/game.js”></script> </body> </html> The game was started with the following statement var mygame; window.onload = function () { mygame = new Phaser.Game(window.innerWidth, window.innerHeight, Phaser.AUTO, “mygame”); mygame.state.add(“Boot”, Boot); mygame.state.add(“Loading”, Loading); mygame.state.add(“TheGame”, TheGame); mygame.state.start(“Boot”); } code of Boot class // —————boot——————— var Boot = { init: function () { mygame.scale.scaleMode = Phaser.ScaleManager.RESIZE; }, preload: function () { mygame.stage.backgroundColor = 0x510100; mygame.load.image(“loading”, “images/loading.png”); }, create: function () { mygame.state.start(“Loading”); } }; When the game was loaded initially on mobile, it took the available space on the mobile screen for that orientation but turning the mobile device to other orientation did not correctly fit in the[…]

How to avoid screen flicker when embedding responsive Phaser game in Bootstrap site

NG Bootstrap, HTML5, jQuery, Phaser

Phaser games can be responsive and will fit in the available space which makes it easy to embed in variety of devices with different sizes. When Phaser games are embeded in a Bootstrap site which is responsive, there can be some flickering on the web page when game is initially loaded. When Phaser games are loaded, it loads in the actual size it was created in and afterwards CANVAS is resized to fit in the available space. The example below is a bootstrap template in which Phaser game is embeded in half of the screen and remaining half screen has some other content. Click the link to load the page to see how the game is being resized to fit in the available space. To make the game load in a nice manner without visible resizing, we need to intially hide the div in which game is loaded. In Phaser boot method we can[…]

How to Handle Orientation Change in Phaser Mobile Web Game

NG HTML5, Mobile, Phaser

If you are not using RESIZE mode for mobile game development and using SHOW_ALL or other scale modes, then you would need to lock the game for one specific orientation. In the previous articles we discussed about the mobile game which was to be published to Android store (Intoduction, Calculation, Game Screen), I also uploaded the game online. The game was played in Landscape mode and I initially developed it for desktop. When I opened it in mobile, though I could open it in Portrait mode and everything was calculated well, I wanted to lock it for Landscape orientation when opened in browser on a mobile device. The orientation was easily locked in Android app by simply changing some configuration option but for browser version I had to write some addtional code. I got some help from Emanuele’s blog on the same topic and borrowed some code. I had to handle it differently[…]

Compile Phaser Game to WIndows 10 Store App

NG HTML5, Phaser, Windows Store App

In previous articles we started building an Android mobile app using Phaser. Check out the articles – Introduction, Calculation, Game Screen, FPS Problem Now since windows has native support for javascript and HTML5, it makes sense to distribute our Phaser games to windows app store to reach new audience. The steps required to compile Phaser game to Windows 10 App is pretty straight forward with no need  for any change in the code. You would need windows 10 to develop and debug the application. If you do not have windows 10 yet, go and download evaluation version of windows and install it in a VM. Microsoft is also providing evaluation version of readymade VMs supporting various technologies such as VMWare, HyperV, Parallels etc which comes pre-loaded with development tools such as Visual Studio 2017 Community edition which you can try for evaluation. https://developer.microsoft.com/en-us/windows/downloads/virtual-machines If you already have windows 10 then download and install[…]

Making of a Responsive Mobile Game App using Phaser: FPS Problem

NG Android, HTML5, Mobile, Phaser

In the previous articles (Intoduction, Calculation, Game Screen) we went through the basic steps required for mobile game creation and looked at calculating and adding responsive behaviour to our game. The same concept applies to the game screen as well. Here is the main game screen The game is a classic dominoes game where players are required to throw their dominoes on their personal train or a special public train, or any other player’s personal train when it becomes public during the play. A lot of tweeing effects are used in the game which is turning out to be the main area to focus. The first step to optimize the game was to reduce the resolution for mobile which I chose to be 960×640 for devices with low processing power and 1350×900 for devices with high processing power. In order to do some benchmarking I integrated some code to measure FPS in[…]
