Careful what you wish for, heres a quick hacked together demo for you from me. But I wouldn't go blatantly copy-pasting any of the code into your own project cause honestly it's a dirty hack-job to just get a basic working example going and nothing more.

I'm so sorry ! Because I'm beginner of progamming. May you code that example for me? I understand you,but I can't know code how to do that. I code for my hobby, I am not Professional Programmer. And my English is not good. (_)! Please...thank you admin !!!
@TwistedTwigleg has the right idea with posting a tutorial link but honestly if you have to ask such a basic question then you should probably dedicate some time to learning the basics of programming before you dedicate yourself to a full blown game development project. I do get that it can get a bit boring though and making a small demo game project can be a fun change between the dry technical tutorials however. :) Good luck and have fun.
edit: forgot the link!
