Please explain Unity basics to me.

I am new to unity, can someone please explain the basics to me? I do not have time to watch the video tutorials since my classes are only 45 minutes long and the tutorials are over an hour. Thanks!

Unity is a tool to create games. You use the Unity Editor to create scenes. Each scene have GameObjects which is the basic building block to represent entities. Behaviour is added to GameObjects through components. One GameObject can have none, one or several added components beyond the transform which represents positioning in the world.

Unity takes care of most details so the developer can focus on productivity and realtively easily publish to a wide array of platforms. If you want to learn more, watch some videos, read the manual or scripting reference.

There is no shortcut, you have to sit down and read, experiment and get your hands dirty.
