在我的项目中需要在里面添加一个翻牌游戏，就研究了一下，在这里只实现了基本的效果。不多说，和大家分享一下。
说到翻牌游戏，大致分为以下几个步骤：
绘制正反面卡牌-------------->洗牌----------------------->翻牌------------------->翻牌判断
这里面应用的一些图片，，，，，，额额额额，，，大家就自己下两个试试，这里也提供不了。。。嘿嘿
1.绘制正反面卡牌
function make_deck()//生成卡组并绘制
{
var i;//
var a_card;//a组卡牌容器
var b_card;//b组卡牌容器
var a_pic;//a组卡牌图片
var b_pic;//b组卡牌图片
var cx = first_x;//初始坐标X=50
var cy = first_y;//初始坐标Y=10
for ( i = 0; i < pairs.length/2; i++) {
/*Canvas绘制图片
* var c=document.getElementById("myCanvas");
var cxt=c.getContext("2d");
var img=new Image()
img.src="flower.png"
cxt.drawImage(img,0,0);*/
a_pic = new Image();
a_pic.src = pairs[i][0];
//绘制卡牌a组
a_card = new Card(cx, cy, card_width, card_height, a_pic, i);//给卡牌属性即卡牌对象生成了，并绘制了背面
deck.push(a_card);//将a组卡牌装进数组deck[]
//绘制与之a组卡牌面相同的b组
b_pic = new Image();
b_pic.src = pairs[i][1];
b_card = new Card(cx, cy + card_height + margin, card_width, card_height, b_pic, i);
deck.push(b_card);// 将b组卡牌装进数组deck[]
cx = cx + card_width + margin;
//cy = cy + card_height + margin;
//note
a_card.draw();
b_card.draw();
}
//绘制后两排
cx=first_x;
cy=first_y+card_height*2+margin*2;
for ( i = 4; i < pairs.length; i++) {
a_pic = new Image();
a_pic.src = pairs[i][0];
//绘制卡牌a组
a_card = new Card(cx, cy, card_width, card_height, a_pic, i);
deck.push(a_card);
//绘制与之a组卡牌面相同的b组
b_pic = new Image();
b_pic.src = pairs[i][1];
b_card = new Card(cx, cy + card_height + margin, card_width, card_height, b_pic, i);
deck.push(b_card);//
cx = cx + card_width + margin;
//cy = cy + card_height + margin;
//note
a_card.draw();
b_card.draw();
}
}2.洗牌
function shuffle()//洗牌
{
var i;
var j;
var temp_info;
var temp_img;
var deck_length = deck.length;
var k;
for ( k = 0; k < 9 * deck_length; k++) {
i = Math.floor(Math.random() * deck_length);//0-16
j = Math.floor(Math.random() * deck_length);//0-16
temp_info = deck[i].info;//第1张
temp_img = deck[i].img;//第1张图片
deck[i].info = deck[j].info;
deck[i].img = deck[j].img;
deck[j].info = temp_info;
deck[j].img = temp_img;
}
}3.翻牌判断
function choose(ev) {
//var out;
var mx;
var my;
//var pick1;
//var pick2;
var i;
//note
if (ev.layerX || ev.layerX == 0) {// Firefox
mx = ev.layerX;
my = ev.layerY;
} else if (ev.offsetX || ev.offsetX == 0) {// Opera
mx = ev.offsetX;
my = ev.offsetY;
}
for ( i = 0; i < deck.length; i++) {
card = deck[i];
if (card.sx >= 0)//牌未被消除
{
//判断点击的是哪一张牌
if (mx > card.sx && mx < card.sx + card.swidth && my > card.sy && my < card.sy + card.sheight) {
if (i != first_card)//如果两次点击同一张牌不做处理
break;
}
}
}
if (i < deck.length) {
if (first_pick)//如果是第一次点击
{
window.addEventListener("load",function(){
var myaudio=document.getElementByIdx_x("a1");
myaudio.volume=0.5;//表示的是播放音量为一半
myaudio.play();
alert("shengyin");
});
first_card = i;
first_pick = false;
//note
ctx.drawImage(card.img, card.sx, card.sy, card.swidth, card.sheight);
} else {
first_pick = true;
//note
second_card = i;
ctx.drawImage(card.img, card.sx, card.sy, card.swidth, card.sheight);
tid = setTimeout(flip_back, 1000);
}
}
}function flip_back() {
if (card.info==deck[first_card].info)//配对成功
{
ctx.fillStyle = table_color;
ctx.fillRect(deck[first_card].sx, deck[first_card].sy, deck[first_card].swidth, deck[first_card].sheight);
ctx.fillRect(deck[second_card].sx, deck[second_card].sy, deck[second_card].swidth, deck[second_card].sheight);
deck[first_card].sx = -1;
deck[second_card].sy = -1;
first_card = -1;
gg();
} else {
deck[first_card].draw();
deck[second_card].draw();
first_card = -1;
}
