坑1
top left 无效，无法居中显示游戏内容
原因; position 不能是 static 改为absolute
<canvas id="unity-canvas"
style=" position: absolute; width: 1920px; height: 1080px;">
</canvas>
坑2
留白改为黑色
<style>
html
{
background-color: black;
}
</style>
修改步骤
1 自适应代码块（'unity-canvas'拼写需要和上发一样 不然无效）
<script>
var unityContainer = document.getElementById('unity-canvas');
function unityContainerResize()
{
var w = window.innerWidth || document.body.clientWidth,
h = window.innerHeight || document.body.clientHeight,
ratio = 16 / 9,
r = w/h;
var setW, setH, setTop, setLeft;
if (r >= ratio) { // 高度撑满
setW = h * ratio;
setLeft = (w - setW) / 2;
} else { // 宽度撑满
setH = w / ratio;
setTop = (h - setH) / 2;
}
unityContainer.style.width = (setW || w) + 'px';
unityContainer.style.height = (setH || h) + 'px';
unityContainer.style.top = (setTop || 0) + 'px';
unityContainer.style.left = (setLeft || 0) + 'px';
}
window.addEventListener('resize', unityContainerResize)
unityContainerResize()
</script>
2 修改了positon属性为absolute
<canvas id="unity-canvas"
style=" position: absolute; width: 1920px; height: 1080px;">
</canvas>
3 修改默认 留白为留黑
<style>
html
{
background-color: black;
}
</style>
完整代码
在unity打包后的文件夹下面名字是index.html
按照上方修改步骤进行
