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

We can customize scrollbar styles to make it look nicer using webkit scrollbar properties. You can change these styles to match your game. This works on chrome and safari. Other browsers do not support these properties but you can still stylize it using normal css styles to match your game. Now add the game code as following

WebP Image Fallback Options

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.

Phaser Cordova Mobile App Crashing on iOS

I recently decided to compile Phaser games to iOS and publish to The App Store. The games were already published on Google Play Store for Android and worked without any issues. I faced few issues after compiling Phaser games for iOS. The first issue which I faced was the game crashing randomly on iOS. After doing further research I found this article on Intel XDK forum which turned out to be the reason for crash. The games were written a while back with older versions of Phaser and I did not get time to upgrade and test this with newer versions of Phaser (CE and higher) so I decided to try the fix specified in this thread and voila, it worked just fine. Here is the code which I borrowed from the thread

Send Email from Asp.Net Application using Google Account and SMTP

In order to send mail from the application we can use SMTP server from Google (which off course has certain limitations). We can use a Google mail account and send the mail using SMTP server from Google. This works very well for Asp.net applications which need to use a simple form such as “Contact Us”. An example of this is explained below. We will use AJAX to send the request to an ASP.Net web service which sends the mail from the server side. Create a web service as following

In order for the method to be called using AJAX make sure to uncomment [System.Web.Script.Services.ScriptService] in the web service code. Add following appsettings in web.config

Change values and replace email and password to your account credentials. Leave SMTPhost and port as-is. We will now create a simple HTML page to input the data
