VSCode配合chrome浏览器调试cocos2d js项目

1.准备阶段

  1. 具备调试功能的VSCode(我的是在win10上,版本是1.17.1)

  2. 在VSCode里下载安装Debugger for Chrome扩展插件。

2.具体操作

  1. 创建一个cocosjs工程 cocos new coco315Pro -l js -d 你的路径 -p 包名

  2. 使用VSCode打开这个工程。 Ctrl + o

  3. 由于cocosjs会加载json文件,所以需要把他部署到一个本地服务器上。我用nodejs创建了一个简单的http服务器,但是不好使,虽然index.html会正常发到浏览器上,但是脚本加载的时候会报unexpected token <的错误。我记得cocos提供的命令cocos run -p web会先启动一个本地服务器,所以通过查阅cocos.py,定位到引擎目录下的tools/cocos2d-console/plugins/plugin_run下的project_run.py里使用BaseHTTPServer创建了一个本地的http服务器。同时打开浏览器,访问127.0.0.1:8000。

     def run_web(self, dependencies):
            if not self._platforms.is_web_active():
                return
    
            from SimpleHTTPServer import SimpleHTTPRequestHandler
            HandlerClass = SimpleHTTPRequestHandler
            ServerClass  = BaseHTTPServer.HTTPServer
            Protocol     = "HTTP/1.0"
            HandlerClass.protocol_version = Protocol
    
            host = self._host
            if self._port is None:
                port = 8000
                port_max_add = 2000
            else:
                port = int(self._port)
                port_max_add = 0
    
            deploy_dep = dependencies['deploy']
            run_root = deploy_dep.run_root
    
            i = 0
            httpd = None
            while (i <= port_max_add):
                port += i
                i += 1
                server_address = (host, port)
                try:
                    cocos.Logging.info(MultiLanguage.get_string('RUN_INFO_HOST_PORT_FMT', (host, port)))
                    httpd = ServerClass(server_address, HandlerClass)
                except Exception as e:
                    httpd = None
                    cocos.Logging.warning(MultiLanguage.get_string('RUN_WARNING_SERVER_FAILED_FMT', (host, port, e)))
    
                if httpd is not None:
                    break
    
            if httpd is None:
                raise cocos.CCPluginError(MultiLanguage.get_string('RUN_ERROR_START_SERVER_FAILED'),
                                          cocos.CCPluginError.ERROR_OTHERS)
    
            # from threading import Thread
            # sub_url = deploy_dep.sub_url
            # url = 'http://%s:%s%s' % (host, port, sub_url)
            # thread = Thread(target = self.open_webbrowser, args = (url,))
            # thread.start()
    
            sa = httpd.socket.getsockname()
            with cocos.pushd(run_root):
                cocos.Logging.info(MultiLanguage.get_string('RUN_INFO_SERVING_FMT', (sa[0], sa[1])))
                httpd.serve_forever()
  4. 我们把启动浏览器的代码注释掉:
       # from threading import Thread
       # sub_url = deploy_dep.sub_url
       # url = 'http://%s:%s%s' % (host, port, sub_url)
       # thread = Thread(target = self.open_webbrowser, args = (url,))
       # thread.start()
  5. 点击VSCode左边栏的Debug图标(甲虫图案),自动弹出一个launch.json文件让你配置。可以参考https://go.microsoft.com/fwlink/?linkid=830387

    我是这样配置的:

    {
        "version": "0.2.0",
        "configurations": [
            {
                "name": "Launch localhost",
                "type": "chrome",
                "request": "launch",
                "url": "http://localhost:8000",
                "sourceMaps": true,
                "webRoot": "${workspaceRoot}"
            }
        ]
    }

3.开始调试

  1. 我们先在cmd里输入:
    cocos run -p web
  2. 然后你就可以打断点,F5调试了

     等我在详细看一下nodejs,再写一个nodejs启一个本地服务器的做法。
