cocos creator 插件开发小知识

编辑器

• 获取预览地址

  /** cocos 编辑器窗口对象 */
  const cocos_window = ((electron as any).remote as typeof electron).BrowserWindow.getAllWindows().find(
  	(v) => v.title !== "CocosCreator" && v.title.includes("Cocos Creator")
  )!;
  /** 预览地址 */
  let preview_url_s = await cocos_window.webContents.executeJavaScript("window.xxx.address");
  
  // 不存在预览地址
  if (!preview_url_s) {
  	await cocos_window.webContents.executeJavaScript(
  		'window.xxx.$refs.qr.parentElement.dispatchEvent(new Event("mouseenter")); window.xxx.$refs.qr.parentElement.dispatchEvent(new Event("click"))'
  	);
  	await new Promise<void>((resolve_f) => {
  		const timer = setInterval(async () => {
  			preview_url_s = await cocos_window.webContents.executeJavaScript("window.xxx.address");
  			if (preview_url_s) {
  				clearInterval(timer);
  				resolve_f();
  			}
  		}, 10);
  	});
  
  	cocos_window.webContents.executeJavaScript('window.xxx.$refs.qr.parentElement.dispatchEvent(new Event("mouseleave"))');
  }
  

窗口

• 获取当前打开的窗口对象

const window_id_ns = electron.BrowserWindow.getAllWindows().map((v) => v.id);
await Editor.Panel.open(config.name_s);
const window = electron.BrowserWindow.getAllWindows().find((v) => !window_id_ns.includes(v.id))!;
