這篇“怎么用git實現羊了個羊游戲”文章的知識點大部分人都不太理解，所以小編給大家總結了以下內容，內容詳細，步驟清晰，具有一定的借鑒價值，希望大家閱讀完這篇文章能有所收獲，下面我們一起來看看這篇“怎么用git實現羊了個羊游戲”文章吧。
以下就是基礎的Hap的page文件：index.ets
build() {
Row() {
Column() {
Canvas(this.context)
.width('100%')
.height('100%')
.onClick((ev: ClickEvent) => {
console.log("screen.xy:"+ev.screenX+":"+ev.screenY)
console.log("xy:"+ev.x+":"+ev.y)
})
.onReady(() =>{
this.context.imageSmoothingEnabled = false
this.drawBlock()
})
}
.height("80%")
.width("100%")
}
.height('100%')
.width('100%')
.backgroundImage($r("app.media.grass"))
.backgroundImageSize(ImageSize.Cover)
}build是基礎頁面的構造函數，用于界面的元素構造，其他的頁面的生命周期函數如下：
declare class CustomComponent {
/**
* Customize the pop-up content constructor.
* @since 7
*/
build(): void;
/**
* aboutToAppear Method
* @since 7
*/
aboutToAppear?(): void;
/**
* aboutToDisappear Method
* @since 7
*/
aboutToDisappear?(): void;
/**
* onPageShow Method
* @since 7
*/
onPageShow?(): void;
/**
* onPageHide Method
* @since 7
*/
onPageHide?(): void;
/**
* onBackPress Method
* @since 7
*/
onBackPress?(): void;
}canvas是畫布組件用于自定義繪制圖形
頁面顯示前會調用aboutToAppear()函數，此函數為頁面生命周期函數
canvas組件初始化完畢后會調用onReady()函數，函數內部實現小游戲的初始頁面的繪制
initBlocks() {
for (let i=0;i<this.avaliableCnt;i++) {
let lineCn = Math.floor(i/3)
let rowCn = Math.floor(i%3)
if (lineCn == 0) {
this.blockList[i] = {
img: "censer",
isShow: true,
x: this.startX+rowCn*30,
y: this.startY,
w: 55,
h: 53,
}
} else if (lineCn == 1) {
this.blockList[i] = {
img: "cloud",
isShow: true,
x: this.startX+rowCn*30,
y: this.startY+lineCn*90,
w: 55,
h: 53,
}
} else if (lineCn == 2) {
this.blockList[i] = {
img: "knif",
isShow: true,
x: this.startX+rowCn*30,
y: this.startY+lineCn*90,
w: 55,
h: 53,
}
}
}
}小游戲的每個卡片都是用canvas繪制的圖片資源，用于進行排列以及點擊判斷所以在此設計了個數據結構
{
img: 卡片資源類型，用于圖片渲染和相似圖片消除
isShow: 卡片是否顯示標志，用于渲染的時候進行判斷
x：卡片渲染左上角橫坐標
y：卡片渲染左上角縱坐標
w：卡片渲染寬度
h: 卡片渲染高度
}現在制作的是用固定方法初始化卡片的方法即渲染3行，每行3個圖片，之后改進可以改成明確一個區域，然后采用隨機算法進行位置和卡片類型生成。
drawBlock() {
//初始化消除區域的卡片
this.blockList.forEach((block)=>{
if (block.isShow) {
let imgItem:ImageBitmap = null
switch(block.img) {
case "censer":
imgItem = this.censerImg
break
case "cloud":
imgItem = this.cloudImg
break
case "knif":
imgItem = this.knifImg
break
default:
imgItem = this.censerImg
break
}
this.context.drawImage( this.cardImg,block.x,block.y,this.blockw,this.blockh)
this.context.drawImage( imgItem,block.x+5,block.y+5,block.w,block.h)
}
})
//初始化選擇卡片區域
this.context.drawImage( this.slotImg,this.slotX,this.slotY,300,39)
let pos = 0
for (let i=0;i<5;i++) {
this.context.drawImage( this.cardImg,this.slotX + pos,this.slotY+40,61,69)
if (i < this.emptyList.length) {
let emptyText = this.emptyList[i]
let pItem = null;
switch (emptyText) {
case "censer":
pItem = this.censerImg;
break;
case "cloud":
pItem = this.cloudImg;
break;
case "knif":
pItem = this.knifImg;
break;
default:
break;
}
if (pItem) {
this.context.drawImage(pItem,this.slotX + pos + 3,this.slotY+40,55,59)
}
}
pos += 60
}
}整個繪制區域分兩個區域：
消除區域：繪制卡片背景和卡片類型，利用初始化的卡片數據進行卡片繪制；
選擇區域：繪制欄桿，卡片背景，以及選擇的卡片
簡單的小游戲主體游戲邏輯為：初始化（之前的章節已經介紹），點擊（選中，選不中，消除，選擇區域滿，消除區域空）流程圖如下：
graph LR
init[初始化] --> click[點擊]
click[點擊] --> isSelect{是否點中}
isSelect -->|點中| yes[點中]
isSelect -->|沒點中| no[沒點中]
yes --> isEmpty{是否選擇區域滿}
isEmpty -->|滿| full[無法消除]
isEmpty -->|不滿| notfull[加入選擇區域]
notfull --> canClear{有3個相同}
canClear -->|能消除| clear[消除]
canClear -->|不能消除| append[進入選擇區域]
append --> 重繪.onClick((ev: ClickEvent) => {

遺留問題：
點擊選擇沒有判斷圖層：可以在卡片數據結構里增加圖層標識，最下面的卡片為圖層標識為1，上面的多一層加1，點中選擇的時候可以判斷，增加是否可以選中的邏輯；
消除區域布局可靈活配置：增加布局配置邏輯，使用數據結構設定布局邏輯，可規定卡片種類，數量，布局行數，列數以及層級
游戲聲音問題：目前ohos不支持音頻播放資源音頻，看之后版本是否支持
