本文實例為大家分享了JS實現紙牌發牌動畫的具體代碼，供大家參考，具體內容如下

先看演示

游戲構建準備

1.準備52張紙牌

2.一張桌布

3.編輯工具為 Visual Code

技術概要

1.對象操作

2.數據操作

3.JS animation動畫

4.全局變量

function desen_x(){

let that = this;

var desen=["h_1","h_2","h_3","h_4","h_5","h_6","h_7","h_8",

"h_9","h_10","h_11","h_12","h_13","p_1","p_2","p_3","p_4"

,"p_5","p_6","p_7","p_8","p_9","p_10","p_11","p_12","p_13"

,"t_1","t_2","t_3","t_4","t_5","t_6","t_7","t_8","t_9","t_10"

,"t_11","t_12","t_13","x_1","x_2","x_3","x_4","x_5","x_6","x_7"

,"x_8","x_9","x_10","x_11","x_12","x_13"];

//將你的撲克前戳名全部存儲到數組中

var Obj = new Object(); //新建一個對象

var array=[];//空數組一個

for(var i=0;i<4;i++){//游戲演示里只需要發4張撲克，所以只要<4

var x=Math.round(Math.random()*52);//隨機數取整*52

Obj[i]=x;//存入到全局變量中 否則每次只能存一個數值

}

console.log(Obj);//打印對象看看是不是4個對象

window.array=[desen[Obj[0]],desen[Obj[1]],desen[Obj[2]],desen[Obj[3]]];

//將存好的數組 帶入撲克全局

}

function send_poker(){ //該方法是發牌事件

console.log(window.array);

//測試你的全局變量是否正常

//并且將傳遞的全局變量帶入temp[]

var temp=[window.array[0],window.array[1],window.array[2],window.array[3]];

var ti=0;

var iamges="../poker/"+temp+".png";//這是圖片的默認路徑 +你的 desen

var creator=document.getElementById("d_back"); //取得操作的dom父元素

var po_1=document.createElement("div");//虛擬生成div

var num = 0; //初始化變量

//po_1.src="../h_1.png";

//img_1.scr="../images/poker/h_1.png";

for(var i=0;i

var that=this;

var img_1=document.createElement("img");

img_1.src+="./images/poker/"+temp[i]+".png";//對創建的img賦值可變的路徑

console.log("等于0時");

var ten=10;

img_1.className="poker_float";//為其指定一個類，也就是默認的初始發牌位置

creator.appendChild(img_1);//生成對象

//"../images/poker/"+temp.i+".png";

}

move_poker();//該方法是自封裝的動畫

}

動畫事件

function move_poker(){ //移動撲克

var node = document.getElementById("d_back").childNodes;//獲取父元素下的所有子節點

console.log(node);//打印出有多少

var n5=node[9];//以要操作的 img對象類為 9開始操作

var n6=node[10];

var n7=node[11];

var n8=node[12];

var popo=anime({//animation動畫可在最后查看

targets: n5, //操作的對象

translateX:-150, //移動到的橫向位置

translateY: -250,//移動到的縱向位置

easing: 'easeInOutQuad',//緩動，不更改css機制

duration:100,//完成時間

});

var popo1= anime({

targets: n6,

translateX:-100,

translateY: -250,

easing: 'easeInOutQuad',

duration:200,

});

var popo2=anime({

targets: n7,

translateX:-50,

translateY: -250,

easing: 'easeInOutQuad',

duration:300,

});

var popo3= anime({

targets: n8,

translateX:0,

translateY: -250,

easing: 'easeInOutQuad',

duration:400,

});

}

function gui(){ //GUI 是將所有節點復位，方便下次發牌

var node = document.getElementById("d_back").childNodes;

var n5=node[9];

var n6=node[10];

var n7=node[11];

var n8=node[12];

var popo4=anime({

targets: [n5,n6,n7,n8],

translateX:0,

translateY: 0,

})

node.removeChild(popo4);

}

animation封裝

function setAnimationsProgress(insTime) { //該方法有多個dom時，則執行異或異步線程模式進行

var i = 0;

var animations = instance.animations;

var animationsLength = animations.length;

while (i < animationsLength) {

var anim = animations[i];

var animatable = anim.animatable;

var tweens = anim.tweens;

var tweenLength = tweens.length - 1;

var tween = tweens[tweenLength];

if (tweenLength) { tween = filterArray(tweens, function (t) { return (insTime < t.end); })[0] || tween; }

var elapsed = minMax(insTime - tween.start - tween.delay, 0, tween.duration) / tween.duration;

var eased = isNaN(elapsed) ? 1 : tween.easing(elapsed);

var strings = tween.to.strings;

var round = tween.round;

var numbers = [];

var toNumbersLength = tween.to.numbers.length;

var progress = (void 0);

for (var n = 0; n < toNumbersLength; n++) {

var value = (void 0);

var toNumber = tween.to.numbers[n];

var fromNumber = tween.from.numbers[n] || 0;

if (!tween.isPath) {

value = fromNumber + (eased * (toNumber - fromNumber));

} else {

value = getPathProgress(tween.value, eased * toNumber);

}

if (round) {

if (!(tween.isColor && n > 2)) {

value = Math.round(value * round) / round;

}

}

numbers.push(value);

}

var stringsLength = strings.length;

if (!stringsLength) {

progress = numbers[0];

} else {

progress = strings[0];

for (var s = 0; s < stringsLength; s++) {

var a = strings[s];

var b = strings[s + 1];

var n$1 = numbers[s];

if (!isNaN(n$1)) {

if (!b) {

progress += n$1 + ' ';

} else {

progress += n$1 + b;

}

}

}

}

setProgressValue[anim.type](animatable.target, anim.property, progress, animatable.transforms);

anim.currentValue = progress;

i++;

}

}
