Code Review
本次 PR 实现了在暂停播放时暂停背景动画的功能,并进行了一些样式优化和问题修复。整体实现清晰,新功能的逻辑明确。
我在代码中发现了一些可以改进的地方:
- 在
PlayerBackground.vue中,audioManager的事件监听器没有在组件卸载时被移除,这会造成内存泄漏。此外,playing状态的初始值可能不准确。 - 在
BackgroundRender.vue中,onUnmounted钩子中使用了一个硬编码的500ms延迟,这使得代码比较脆弱,未来难以维护。
我已经在具体的代码行上提出了修改建议,希望能帮助你提升代码质量。

在 onUnmounted 钩子中使用 setTimeout 和一个硬编码的 500ms 延迟来处理 dispose 调用,虽然可以解决背景立即消失的问题,但这种方式比较脆弱。这个延迟时间很可能与 CSS 过渡动画的持续时间有关,如果动画时间在别处被修改,这里的代码也需要手动更新,容易导致不一致和未来的维护困难。
为了提高代码的可维护性和健壮性,建议将 500 这个“魔术数字”提取为一个有意义的常量,并添加注释说明其用途以及与动画时长的关联。
bgRenderRef.value?.pause();
// 延迟销毁以等待过渡动画完成,此值应与 CSS 过渡时间保持一致
const FADE_OUT_DURATION = 500;
setTimeout(() => {
if (bgRenderRef.value) {
bgRenderRef.value.dispose();
bgRenderRef.value = undefined;
}
}, FADE_OUT_DURATION);

通过设置 `flowSpeed` 为 `0` 来暂停动画,这样貌似没什么问题 除此之外,还优化了一些样式和问题 为 `BackgroundRender` 的 `dispose` 设置了 500ms 的延迟以修复点击关闭按钮后背景立即消失的问题 删掉了 `PlayerControl` 里一些地方的 `cursor: pointer;`
