We provide the two backgrounds from our spritesheet as parameters.Unity Technologies have announced their next big example game for other developers to learn from. The Background is a Sprite GameObject which has a RandomBackgroundScript attached.

We have various objects made children of our perspective camera and the Flappy bird. Now, let’s take a more detailed look at our scene. Then, we created a small animation to simulate the flight course of the bird (this can be easily accomplished if you drag-drop the relevant sprites into the scene).

First of all, we used Unity’s spritesheet editor to “slice” the spritesheet and get references to specific sprites So, let’s start with the small tutorial! This game’s development has many aspects, we’ll attempt to touch all of them one by one. For debugging purposes, don’t forget to check the Visual Studio tools for Unity here. Game code was written in Visual Studio (check the free Community edition here). The sprite sheet used was found here whereas the sounds were found here: Needless to mention that all graphics and sounds found in the tutorial are used only for educational purposes and do not intend to harm any intellectual property at all circumstances. Hence, I decided to give it a shot and recreate it using Unity. Unless you’ve been living in a cave or visiting outer space, you have certainly played Flappy Bird, one of the most successful games for mobile devices. Update: If you’re trying the downloaded game in Unity 5, uncheck the “Apply Root Motion” on the Animator component on the flappy GameObject and everything should work like a charm.
