Unity 使用this关键字进行函数拓展 - GameObject

Example:

      private void Start()
      {
         var testComponent = gameObject
              .Activate()
              .Deactivate()
              .Name("")
              .Layer(0)
              .Layer("")
              .Tag("")
              .GetComponentForcibly(typeof(LineRenderer));
         bool isActive = testComponent
              .Activate()
              .Deactivate()
              .Name("")
              .Layer(0)
              .Layer("")
              .Tag("")
              .IsActive();
      }
