 ## 6.异闻录-FAQ
+- **代码查找组件报错**：确认获取物体的名字和物体实际名字一致。
+- **代码加载InputActionAsset报错**：确认处于`Resources`文件夹下，名字和查找名字一致。
 - **移动不播放动画**：确认动画控制器的参数名字和脚本中设置的一样。
 - **动画只播放一遍**：检查是否勾选循环播放，在模型上看。
-- **动画状态切换有延迟**：确认动画控制器中连接线的HasExitTime是否勾选。
+- **动画状态切换有延迟**：确认动画控制器中连接线的`HasExitTime`是否勾选。
 
 完成以上步骤，即可得到一个带动画的第三人称控制器。[项目地址](http://home.gtuantuan.online:8300/TuanTuan/StudyCase)
