How does Matlab realize gluttonous Snake Mini Game

Editor to share with you how to achieve gluttonous Snake Mini Game, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to understand it!

Make up the picture:

Yeah, it's kind of like a snake in the battle of the Snake.

Then improvements include:

Do not report an error setting when closing the window, because the function timer is used, it will report an error when closing the image, so we can add a callback function:

Set (gcf,'tag','co','CloseRequestFcn',@clo); function clo (~, ~) stop (game) delete (findobj ('tag','co')); clf close end

It means that the function clo is called every time there is a closed request.

Then to prevent him from prompting you to call close recursively

Plus delete (findobj ('tag','co')); delete the previous settings.
