Mini-app-implemented greedy Snake game [Source Code download], greedy snake source code download

This article describes the snake games implemented by applets. We will share this with you for your reference. The details are as follows:

Let's take a look at the running effect:

The Code is as follows:

Page layout pages/snake. wxml:

<! -- Snake. wxml --> <view class = "control" bindtouchstart = "tapStart" bindtouchmove = "tapMove" bindtouchend = "tapEnd"> <view class = "score"> <view class = "title "> snake </view> <view class =" scoredetail "> <view class =" scoredesc "> score </view> <view class =" scorenumber ">{{ score}} </view> <view class = "scoredetail"> <view class = "scoredesc"> highest history </view> <view class = "scorenumber"> {{maxscore }}</view> <vi Ew class = "ground"> <view wx: for = "{ground}" class = "rows" wx: for-item = "cols"> <view wx: for = "{cols}" class = "block _ {item}"> </view> <modal class = "modal "hidden =" {modalHidden }}" no-cancel bindconfirm = "modalChange"> <view> the game is over, start again? </View> </modal> </view>
