我是一名图形艺术家，对编码完全陌生。我正在尝试制作一个简单的基于 HTML5 的游戏模型。 我想要做的是将一个 Sprite 动画交换到另一个 Sprite 动画 onclick。每个 Sprite 动画都有不同的大小和帧数。
第一个图像上的动画已经打开，当单击图像时，该动画将被另一个动画替换。进行该切换后，将显示得分动画(另一个 Sprite 动画)。
我已经尝试了很多不同的 Javascript，但到目前为止没有什么好的结果。我只能想出一个脚本，但它根本行不通。 (两张图片相互重叠)我确定我做的事情完全错了，但我真的需要你们的帮助。
function change(){
var image = document.getElementById('pupwag01');
image.src = "images/pup01-win-sprite.png";
} #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;}

假设您想要通过单击按钮或图像本身来更改 sprite 图像。以下是您可以如何做到这一点。
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 = "/image/rl1BU.jpg"
}else{
//if win class does't exists change src to normal image of puppy
this.src = "/image/O144b.jpg";
}
});
//adding click event listener to win button
winButton.addEventListener('click', function(){
puppyImage.src = "/image/rl1BU.jpg";
})
//adding click event listener to normal button
normalButton.addEventListener('click', function(){
puppyImage.src = "/image/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');
});#puppy-background{
height: 300px;
width: auto;
background-image: url('/image/O144b.jpg');
background-repeat: no-repeat;
}
#puppy-background.win{
background-image: url('/image/rl1BU.jpg');
