I am trying to customize the html5 template.

Quoting the docs on canvasResizePolicy = 1:

means Godot will resize the canvas on start, and when changing window size via engine functions.

But I could not find how to those “engine functions”

What I did find are functions that do would be helpful, like “updateSize”:

godotengine/godot/blob/64e8eee3c626a61a97a388feae8fa3deffff4776/platform/javascript/js/libs/library_godot_display.js#L577


      
          			}
          			return 0;
          		},
          		_updateGL: function () {
          			const gl_context_handle = _emscripten_webgl_get_current_context(); // eslint-disable-line no-undef
          			const gl = GL.getContext(gl_context_handle);
          			if (gl) {
          				GL.resizeOffscreenFramebuffer(gl);
          			}
          		},
          		updateSize: function () {
          			const isFullscreen = GodotDisplayScreen.isFullscreen();
          			const wantsFullWindow = GodotConfig.canvas_resize_policy === 2;
          			const noResize = GodotConfig.canvas_resize_policy === 0;
          			const wwidth = GodotDisplayScreen.desired_size[0];
          			const wheight = GodotDisplayScreen.desired_size[1];
          			const canvas = GodotConfig.canvas;
          			let width = wwidth;
          			let height = wheight;
          			if (noResize) {
          				// Don't resize canvas, just update GL if needed.

But I found no way of calling those as they are sealed away inside the Godot engine object and not callable from the outside.

Thanks for any pointers
