我使用的是unity 2019.4 LTS版
一共有两步
1 在Index.html中修改
<!DOCTYPE html>
<html lang="en-us">
<head>
<meta charset="utf-8">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Unity WebGL Player | DMJ</title>
<link rel="shortcut icon" href="TemplateData/favicon.ico">
<link rel="stylesheet" href="TemplateData/style.css">
<script src="TemplateData/UnityProgress.js"></script>
<script src="Build/UnityLoader.js"></script>
<script>
var unityInstance = UnityLoader.instantiate("gameContainer", "Build/DMJ_WebApp.json", {onProgress: UnityProgress});
</script>
</head>
<!-- 调用 OnResize方法, 当用户改变浏览器尺寸时, 屏幕会自适应 -->
<body onResize="ChangeCanvas()">
<div class="webgl-content">
<!-- 设置长宽都是百分百填充 -->
<div id="gameContainer" style="width:100%; height:100%"></div>
<!-- 底部的显示条，不需要的话直接删掉-->
<div class="footer">
<div class="webgl-logo"></div>
<div class="fullscreen" onclick="gameInstance.SetFullscreen(1)"></div>
<div class="title">DMJ</div>
</div>
</div>
<!--添加自动设置分辨率的方法-->
<script type="text/javascript">
function ChangeCanvas()
{
document.getElementById("unityInstance").style.width = window.innerWidth + "px";
document.getElementById("unityInstance").style.height = window.innerHeight + "px";
document.getElementById("#canvas").style.width = window.innerWidth + "px";
document.getElementById("#canvas").style.height = window.innerHeight + "px";
}
</script>
</body>
</html>
2 修改css 的内容 位置在打包出来的文件/TemplateData/style.css
.webgl-content * {border: 0; margin: 0; padding: 0}
/*主要是这里 添加 width: 100%; height: 100%;*/
.webgl-content {position: absolute; top: 50%; left: 50%; width: 100%; height: 100%; -webkit-transform: translate(-50%, -50%); transform: translate(-50%, -50%);}
.webgl-content .logo, .progress {position: absolute; left: 50%; top: 50%; -webkit-transform: translate(-50%, -50%); transform: translate(-50%, -50%);}
.webgl-content .logo {background: url('progressLogo.Light.png') no-repeat center / contain; width: 154px; height: 130px;}
.webgl-content .progress {height: 18px; width: 141px; margin-top: 90px;}
.webgl-content .progress .empty {background: url('progressEmpty.Light.png') no-repeat right / cover; float: right; width: 100%; height: 100%; display: inline-block;}
.webgl-content .progress .full {background: url('progressFull.Light.png') no-repeat left / cover; float: left; width: 0%; height: 100%; display: inline-block;}
.webgl-content .logo.Dark {background-image: url('progressLogo.Dark.png');}
.webgl-content .progress.Dark .empty {background-image: url('progressEmpty.Dark.png');}
.webgl-content .progress.Dark .full {background-image: url('progressFull.Dark.png');}
/*如果你要保存 footer模块, 然后又要让footer显示在最顶部,这样处理*/
.webgl-content .footer {margin-top: -45px; margin-left: 5px; margin-right: 5px; z-index: 1; position: relative; height: 38px; line-height: 38px; font-family: Helvetica, Verdana, Arial, sans-serif; font-size: 18px;}
.webgl-content .footer .webgl-logo, .title, .fullscreen {height: 100%; display: inline-block; background: transparent center no-repeat;}
.webgl-content .footer .webgl-logo {background-image: url('webgl-logo.png'); width: 204px; float: left;}
.webgl-content .footer .title {margin-right: 10px; float: right;}
.webgl-content .footer .fullscreen {background-image: url('fullscreen.png'); width: 38px; float: right;}
