对于 Unity WebGL 构建，无法覆盖 div 全屏 Canvas
Can Not Overlay div Over Full Screen Canvas for Unity WebGL Build
我想在全屏 Unity 前面叠加一个 div - Canvas。当它不是全屏时我可以覆盖它但无法弄清楚如何在 canvas 处于全屏模式时覆盖 Unity Canvas 前面的 div。
我在 Unity WebGL 构建的 index.html 文件中加载了 CSS。我粘贴在下面。
<style>
.loader {
position: absolute;
left: 50%;
top: 50%;
z-index: 999;
width: 120px;
height: 120px;
margin: -76px 0 0 -76px;
border: 16px solid #f3f3f3;
border-radius: 50%;
border-top: 16px solid #babfc2;
-webkit-animation: spin 2s linear infinite;
animation: spin 2s linear infinite;
}
/* Safari */
@-webkit-keyframes spin {
0% { -webkit-transform: rotate(0deg); }
100% { -webkit-transform: rotate(360deg); }
}
@keyframes spin {
0% { transform: rotate(0deg); }
100% { transform: rotate(360deg); }
}
</style>
<div id="modelLoading" class="loader"></div>
我将此 CSS 用作 class 用于 div，基本上，div 显示在正常的 window 中，如图所示下方，但它在全屏时消失 window。还尝试过：全屏但没有用。
我在下面添加了屏幕截图和完整的 HTML 代码。
感谢您的帮助。

您可以制作整个 canvas 容器，而不是要求统一库制作 canvas 全屏
fullscreen 自己使用 JavaScript 和 DOM API。
这样你就会有更多的控制权。请参阅下面的演示代码。解释在代码注释中。
由于您尚未共享 CSS 和 javascript 库，因此我添加了自己的样式以用于演示目的。
将整个代码放在本地 .html 文件中，然后 运行 在浏览器中。然后按 Fullscreen。您会注意到旋转加载器与 canvas.
一起全屏显示

我想如果你在 chrome 开发者控制台中调试 unityInstance.SetFullscreen(1) 然后你会发现它做了类似的事情：调整 canvas 的大小并调用 requestFullscreen() 就可以了。
注意： Whosebug 和其他在线 html 编辑器不允许全屏，因此您必须尝试本地 .html 文件中的代码。

我想如果你在 chrome 开发者控制台中调试 unityInstance.SetFullscreen(1) 然后你会发现它做了类似的事情：调整 canvas 的大小并调用 requestFullscreen() 就可以了。
注意： Whosebug 和其他在线 html 编辑器不允许全屏，因此您必须尝试本地 .html 文件中的代码。
修复后您的代码将如下所示：

您可能需要调整 fullScreenContainer 元素的样式。
