Question

我是一位图形艺术家，对编码非常陌生。我试图制作一个简单的基于HTML5的游戏模型。我想要做的是将一个精灵动画交换到另一个精灵动画onclick。每个精灵动画都有不同的大小和帧数。

第一张图片上的动画已经开启，点击图片时，该动画将被另一幅动画取代。进行切换后，会显示乐谱动画（另一个精灵动画）。

我尝试过很多不同的Javascript，但到目前为止还没有很好的结果。我只能提出一个脚本而且它不起作用。（两张图片相互重叠）我确定我做错了什么，但我真的需要你帮忙。

＆＃13;

function change(){
			var image = document.getElementById('pupwag01');
			image.src = "images/pup01-win-sprite.png";
		}

＆＃13;

#null01{
	position: absolute;
	top: 700px;
	left: 100px;
}

#pupwag01 {
	background-image: url('../images/puppy01sprite.png');
	width: 173px;
	height: 221px;
	position: relative;
	animation: pupwag01 1s steps(6) infinite;
}

@keyframes pupwag01 {
	0% {background-position: 0px;}
	100% {background-position: -1038px;}
}
#null01a{
	position: absolute;
	top: 680px;
	left: 50px;
}
#pupwin01 {
	background-image: url('../images/pup01-win-sprite.png');
	width: 308px;
	height: 191px;
	position: relative;
	animation: pupwin01 .5s steps(3) infinite;
	background-repeat: no-repeat;
}

@keyframes pupwin01 {
	0% {background-position: 0px;}
	100% {background-position: -924px;}
}

#nullscore01{
	position: absolute;;
	top: 600px;
	left: 110px;
}

#score01{
	background-image: url('../images/score-sprite01.png');
	width: 150px;
	height: 200px;
	position: relative; 
	animation: score01 1s steps(24) 1;
}

@keyframes score01 {
	0% {background-position: 0px;}
	100% {background-position: -3600px;}
}

Answer 1

假设您想要在单击按钮或图像本身时更改精灵图像。这是你如何做到的。

＆＃13;

var puppyImage = document.getElementById('puppy-image');
var puppyBackground = document.getElementById('puppy-background');

var winButton = document.getElementById('button-win');
var normalButton = document.getElementById('button-normal');

//adding click event listener to puppy-image

puppyImage.addEventListener('click', function(e){
	// adding/removing class `win`
	this.classList.toggle('win');
	if(this.classList.contains('win')){
		//if win class exists, change src to win image of puppy
		this.src = "https://i.stack.imgur.com/rl1BU.jpg"
	}else{
		//if win class does't exists change src to normal image of puppy
		this.src = "https://i.stack.imgur.com/O144b.jpg";
	}
});

//adding click event listener to win button
winButton.addEventListener('click', function(){
	puppyImage.src = "https://i.stack.imgur.com/rl1BU.jpg";
})

//adding click event listener to normal button
normalButton.addEventListener('click', function(){
	puppyImage.src = "https://i.stack.imgur.com/O144b.jpg";
})

//adding click event listener to element with puppy background image.
puppyBackground.addEventListener('click', function(e){
	//toggling class `win`, background will change using css.
	this.classList.toggle('win');
});

＆＃13;

#puppy-background{
	height: 300px;
	width: auto;
	background-image: url('https://i.stack.imgur.com/O144b.jpg');
background-repeat: no-repeat;
}
#puppy-background.win{
	background-image: url('https://i.stack.imgur.com/rl1BU.jpg');	
}
