如果需要本地测试,建议使用备忘的资源,这样它就无需本地静态虚拟服务器的支持,若此,将第 20 行代码注释或删掉。
源码第 21 行引用我重新封装的全屏模块,它实际上还集成对音频控制按钮的封装,只要指定按钮标识,代码在第 22 行:
FS(papa, player);
其中的 player 就是按钮的 id 标识。此外,如果启用了按钮管理,该模块还封装对视频的管理。
若需要启用全屏模块的附加功能,请在CSS设置相关的CSS,具体代码请参考第 4、5、6、7、8 这几行。
这个效果漂亮,这是在哪个球上了 花飞飞 发表于 2025-5-1 20:29
咦?今天居然评到没分后面补上吧。。
抢楼了{:4_170:} 这个不是花潮,是粒子潮{:4_173:}
开篇可看到远远的一团从小到大扑面而来。。。。
那是世界的尽头么。。
那个飞轮的小播放在粒子中心转动时带起粒子风。。 小播加了个黄色的光晕,触碰有变化。。
全屏按纽也给了个触 碰变黄的效果,更加显眼了
每次看白老师的作品都能看到各种不同的细微改进{:4_173:} 马黑黑 发表于 2025-5-1 20:35

这个也看到了。FS是昨天修改好的 话说这个小粒子支持图片不呢?{:4_173:} 马黑黑 发表于 2025-5-1 20:40

目前不支持。我刚刚接触 three.js,能画个矩形出来就已经相当不错了,可以自己给自己奖励两包华子 马黑黑 发表于 2025-5-1 20:41

代码一排排看过去时发现的。。。还给粒子整了画布{:4_173:} 花飞飞 发表于 2025-5-1 20:42

three.js 就是使用canvas画布渲染最终结果的。当然,可以不管这些,一样可以运行。 马黑黑 发表于 2025-5-1 20:43

华子容易,这个我可以包了。。{:4_173:}
three.js又是个什么好东东,能做这么炫的效果
我的天,你一手设计出来的,这么大工程。。。。
赞个。。。 马黑黑 发表于 2025-5-1 20:44
{:4_170:}这个新梗,忍不住要拿来用用,多好玩。。
大不了回送你一个{:4_204:}
