html - 调整统一 webgl 画布无响应的大小

Question

我正在尝试调整 Unity 的 WebGL 画布以适应浏览器窗口的纵横比。我不希望它响应，只需调整大小以适合窗口。

如何在 css/html 中实现这一点？

我尝试将窗口的宽度和高度都设置为 100%，但它仍然无法缩放。我究竟做错了什么？

var buildUrl = "Build";
      var loaderUrl = buildUrl + "/WebGL_ResponsiveBuild.loader.js";
      var config = {
        dataUrl: buildUrl + "/WebGL_ResponsiveBuild.data",
        frameworkUrl: buildUrl + "/WebGL_ResponsiveBuild.framework.js",
        codeUrl: buildUrl + "/WebGL_ResponsiveBuild.wasm",
        streamingAssetsUrl: "StreamingAssets",
        companyName: "DefaultCompany",
        productName: "WebGL",
        productVersion: "0.1",
      };

      var container = document.querySelector("#unity-container");
      var canvas = document.querySelector("#unity-canvas");
      var loadingBar = document.querySelector("#unity-loading-bar");
      var progressBarFull = document.querySelector("#unity-progress-bar-full");
      var fullscreenButton = document.querySelector("#unity-fullscreen-button");
      var mobileWarning = document.querySelector("#unity-mobile-warning");

      // By default Unity keeps WebGL canvas render target size matched with
      // the DOM size of the canvas element (scaled by window.devicePixelRatio)
      // Set this to false if you want to decouple this synchronization from
      // happening inside the engine, and you would instead like to size up
      // the canvas DOM size and WebGL render target sizes yourself.
      // config.matchWebGLToCanvasSize = false;

      if (/iPhone|iPad|iPod|Android/i.test(navigator.userAgent)) {
        container.className = "unity-mobile";
        // Avoid draining fillrate performance on mobile devices,
        // and default/override low DPI mode on mobile browsers.
        config.devicePixelRatio = 1;
        mobileWarning.style.display = "block";
        setTimeout(() => {
          mobileWarning.style.display = "none";
        }, 5000);
      } else {
        canvas.style.width = "1920px";
        canvas.style.height = "1080px";
      }
      loadingBar.style.display = "block";

      var script = document.createElement("script");
      script.src = loaderUrl;
      script.onload = () => {
        createUnityInstance(canvas, config, (progress) => {
          progressBarFull.style.width = 100 * progress + "%";
        }).then((unityInstance) => {
          loadingBar.style.display = "none";
          fullscreenButton.onclick = () => {
            unityInstance.SetFullscreen(1);
          };
        }).catch((message) => {
          alert(message);
        });
      };
      document.body.appendChild(script);

var w = window.innerWidth;

var h = window.innerHeight;

使用 vanilla js 获取窗口大小并在此处添加它们：

    canvas.style.width = "1920px";  <-- w
    canvas.style.height = "1080px"; <-- h
