I can't see textures in Game Engine I unwrapped the plane and cube using UV unwrap. I added an Image. My view is set to texture. But when I press P the textures are not shown. I cant figure out the problem.

I made the project using this tutorial - https://www.youtube.com/watch?v=ZBVoKL3sbnw

This is my project file - https://drive.google.com/open?id=0Bzymlv8wN9TiZ2Mwb2lDRWJCSHM

I saw many similar questions on this forum but cant figure out the problem. I am a beginner and any help would be appreciated.
You need to make a material for your object—go to the Materials tab (looks like a ball) in the panel on the right and hit the plus button. Then to to the Textures tab, one to the right. You should be able to add your image there.
