This video goes through the process of making an augmented reality app with Unity 3D and the Vuforia plugin. An image of your Pokemon card gets loaded into an image database and when your phone camera picks up that image it renders the 3d version of that Pokemon over top of the card. This tutorial then goes through how to set up two attacks, water and fire, so when you hit a button on the app the Pokemon performs that attack. I tried to gear this tutorial towards beginners so sorry that it is a little long. I also see some value in leaving mistakes in the video as well, so beginners can learn how to recover. Also, Unity allows you to build apps cross platform, so this app can be built for Android or iPhone (IOS).
Let me know in the comments what you want to see in the next video!
