Troubleshooting Tips故障排除提示

Issues Arise 问题出现

As you work through the hands-on activities in this course, you may encounter issues due to the following:
在您完成本课程中的动手活动时，可能会遇到以下问题：

1. You are working on a different version of Unity - Unity is updated continuously. While most upgrades are seamless, there are times where an upgrade introduces a new bug, changes the interface slightly, adds new functionality, and/or modifies the way things work.
   您正在使用 Unity 的不同版本——Unity 持续更新。虽然大多数升级都是无缝的，但有时升级会引入新的错误，稍微改变界面，增加新功能，以及/或修改事物的工作方式。
2. You are working on a different platform - the videos are created with the Windows version of the Unity Editor. You may be using the MacOS or Linux version of the Unity Editor. Fortunately, the editor is nearly identical across platforms. There are a few minor differences in hot keys. For example, the Mac using the Command key for menu shortcuts (such as COMMAND-S = Save) while Windows uses the CTRL key (such as CTRL-S = Save). The Mac and Windows file systems (where things are saved) and desktops are slightly different as well. Overall, these differences are fairly minor and I try to point them out along the way.
   您正在使用不同的平台 - 视频是用 Unity 编辑器的 Windows 版本创建的。您可能在使用 Unity 编辑器的 MacOS 或 Linux 版本。幸运的是，编辑器在不同平台上的几乎完全相同。在热键上存在一些细微的差异。例如，Mac 使用 Command 键作为菜单快捷键（如 COMMAND-S = 保存），而 Windows 使用 CTRL 键（如 CTRL-S = 保存）。Mac 和 Windows 文件系统（保存内容的地方）以及桌面也有所不同。总的来说，这些差异相当小，我会沿途指出它们。
3. You missed a step or misunderstood a step - there is a lot of information presented in the hands-on projects - both step-by-step instructions and conceptual ideas. I do suggest pausing the video so you can follow along and replaying any parts of the video that you missed or find confusing.
   您错过了一步或理解错了步骤——动手项目中提供了大量信息，包括逐步指导和概念想法。我确实建议您暂停视频，以便跟随并重新播放您错过或觉得困惑的部分。

Take Action 采取行动

If you encounter a problem with your project, such as you are receiving an error message that I am not receiving or the behavior of your project differs from what is presented, try the following steps:
如果您在项目中遇到问题，例如您收到我未收到的错误消息或您项目的行为与展示的不同，请尝试以下步骤：

1. Rewatch the lecture and double-check your work. And note that the issue may have actually come up due to something you missed in a previous step OR a change in Unity itself.
   重新观看讲座并仔细检查你的工作。注意，问题可能实际上是由于你在之前的步骤中遗漏了某些内容，或者是因为 Unity 本身发生了变化。
2. For common issues across learners, I will post a "Solutions to Common Issues" (reading or lecture) after the lecture where the issue arose. If you see a "Solutions to Common Issues" lecture, check it out.
   对于学习者普遍存在的问题，我将在问题出现后的讲座后发布“常见问题解决方案”（阅读或讲座）。如果您看到“常见问题解决方案”讲座，请查看。
3. Browse or search the Coursera discussion forums. If it is a common issue, someone else probably has encountered it and posted the question and others may have already posted a solution.
   浏览或搜索 Coursera 讨论区。如果是常见问题，可能有人已经遇到过并提出了问题，其他人可能已经发布了解决方案。
4. Use Google (or your favorite internet search engine) to search for a solution. Unity has a great community around it. You likely will find answers to issues on the Unity Community website, Stack Overflow, or elsewhere on the web.
   使用谷歌（或您喜欢的搜索引擎）搜索解决方案。Unity 拥有庞大的社区。您很可能会在 Unity 社区网站、Stack Overflow 或其他网络平台上找到问题的答案。
5. If you don't find an answer, post your question on Coursera in the appropriate discussion forum. Our great community of learners are great at helping each other out. I will also try to answer as many questions as I can.
   如果您找不到答案，请在 Coursera 的相关讨论区发帖提问。我们庞大的学习社区擅长互相帮助。我也会尽力回答尽可能多的问题。
