一、简介
基于matlab GUI贪吃蛇游戏(难度、地图、音乐)
二、源代码
function snake(cmd)
%SNAKE Graphical User Interface for playing "Nokia Classic Game" Snake.
%
% The Game:
% Make the snake grow longer by directing it to the food.
% Extra bonus points are given from hearts, eat them as fast as possible
% as amount of bonus points decreases with time.
% Higher level gives more points for the food but will also make it
% tougher to steer a long snake as speed increaces.
% Five different mazes as well as play w/o maze are possible.
%
% Game Controls:
% Steer snake using arrow keys. Pause game with ‘p‘ or space.
%
% Example:
% snake % Start Main Snake Interface
