【游戏】基于matlab GUI贪吃蛇游戏【含Matlab源码 1146期】

一、简介

基于matlab GUI贪吃蛇游戏

二、源代码

function varargout = Snake(varargin)
% SNAKE M-file for Snake.fig
%      SNAKE, by itself, creates a new SNAKE or raises the existing
%      singleton*.
%
%      H = SNAKE returns the handle to a new SNAKE or the handle to
%      the existing singleton*.
%
%      SNAKE('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in SNAKE.M with the given input arguments.
%
%      SNAKE('Property','Value',...) creates a new SNAKE or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Snake_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Snake_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
