Unity/WebGL/画面縦横幅拡大

WebGLで出力されてたcanvasを100%にする方法

1. http://corevale.com/unity/1636 にある以下の.webgl-content * {}スタイルシートで、TemplateData/style.cssを更新
2. index.htmlに記載されてる縦幅横幅を100%に変更。
3. 出力されたhtmlに以下記載されてることを確認

<link rel="stylesheet" href="TemplateData/style.css">

リサイズ対応

canvas.style.width = "{{{ WIDTH }}}px";
canvas.style.height = "{{{ HEIGHT }}}px"; 

上記辺りのところを以下に変更

function loadWindow() {
    if (document.documentElement.clientWidth / document.documentElement.clientHeight < {{{ WIDTH }}} / {{{ HEIGHT }}}) {
        canvas.style.width = "100%";
        canvas.style.height = (document.documentElement.clientWidth * {{{ HEIGHT }}} / {{{ WIDTH }}}) + "px";
    } else {
        canvas.style.height = "100%";
        canvas.style.width = ((document.documentElement.clientHeight - 20) * {{{ WIDTH }}} / {{{ HEIGHT }}}) + "px";
    }
    window.setTimeout(resizeWindow, 5000);
}
function resizeWindow() {
    if (document.documentElement.clientWidth / document.documentElement.clientHeight < {{{ WIDTH }}} / {{{ HEIGHT }}}) {
        canvas.style.width = "100%";
        canvas.style.height = (document.documentElement.clientWidth * {{{ HEIGHT }}} / {{{ WIDTH }}}) + "px";
    } else {
        canvas.style.height = "100%";
        canvas.style.width = ((document.documentElement.clientHeight - 20) * {{{ WIDTH }}} / {{{ HEIGHT }}}) + "px";
    }
}
window.addEventListener('resize', resizeWindow);
window.addEventListener('load', loadWindow);

右に表示されてしまうのを中央表示に変更する方法

TemplateData/style.css

body {
    text-align: center;
}
