Dependency Injection - Simplest tutorial ever!


I have been hearing about Dependency Injection often. So I googled and found this very useful post by James Shore. The article begins with the below excerpt.

When I first heard about dependency injection, I thought, "Dependendiwhatsit?" and promptly forgot about it. When I finally took the time to figure out what people were talking about, I laughed. "That'sall it is?"
"Dependency Injection" is a 25-dollar term for a 5-cent concept. That's not to say that it's a bad term... and it's a good tool. But the top articles on Google focus on bells and whistles at the expense of the basic concept. I figured I should say something, well, simpler.

DoTween - The Big Demo

Image
I love DoTween , and have been using it extensively at work and personal projects, ever since I heard of it. Tweens are a great and cheap way to get a polished look for all transitions and animations in your game or mobile app. Stop coding movement by hand for menu items, HUDs, simple translations etc. if you are still doing it. So I made a small 2d demo in Unity5 with DoTween, where you can play with different types of tweens, including an option to choose a different tween for different axes (X and Y) Its open-source btw, and you can play with the code yourself on github . Click to open the unity web player in new tab (Firefox, Safari recommended) If Chrome blocks, follow instructions . Easing is an important component of making your games and interactive experiences Juicy. If you don't know what Juicyness is watch this amazingly cool super awesome video of two game developers showcasing their demo.

How to install Android SDK without internet connection I searched all over the internet and found no posts like this, hence I'm making one hoping it would be helpful for a lot of people. The magic URL used to be  - http://dl-ssl.google.com/android/repository/repository.xml  (Outdated) That is the XML file from which the URL for downloading the SDK packages are obtained.

You will find a block under tag SDK 4.0.3 like this <sdk:arch...
