基于HTML5 SVG的超酷打击乐器特效

简要教程

这是一款使用SVG结合TweenMax.js制作的超酷打击乐特效。该特效中使用SVG制作水桶和瓢盆等模拟打击乐器,用户点击相应的乐器时会发出相应的乐器音效,非常有趣。

你可以使用键盘来控制各种乐器,有效的键盘按键有:B、D、F、G、H、J、K、L、N、Y。当你按下上面的任意键时,屏幕中就会出现相应的按键提示。

使用方法

HTML结构

所有的乐器都是使用SVG来制作,所有的乐器都已<g>元素作为分组,代码如下:

乐器的音效通过<audio>元素来实现。

<audio id="can1-Audio">     <source src="vedio/can1.mp3" preload="auto" type="audio/mp3" /> </audio> <audio id="can2-Audio">     <source src="vedio/can2.mp3" preload="auto" type="audio/mp3" /> </audio> ......

JAVASCRIPT

特效中通过TweenMax.js来控制用户于乐器之间的交互。实现代码页非常简单,例如can1乐器的JS代码如下:

// 鼠标点击can1时的缩放效果 var can1tl = new TimelineMax({   paused: true }); can1tl.to(can1, 0.1, {scaleX: 1.06, transformOrigin: "50% 50%", ease: Expo.easeOut}) .to(can1, 0.1, {scaleY: 0.95, transformOrigin: "50% 50%", ease: Expo.easeOut}, '0') .to(can1, 0.2, {scale: 1, transformOrigin: "50% 50%", ease: Elastic.easeOut});   // Can1的音效 function playCan1Audio() {   can1Audio.currentTime = 0;   can1Audio.play(); }   // 用户点击时执行的动作 function can1hit(){   can1tl.restart();   can1tl.play();   playCan1Audio(); }   // 附加鼠标点击事件 can1.addEventListener("click", can1hit);
