Unity Help Page

Download/Installation

• Unity version: work with the latest, all examples in class are based on Unity-2022.3.20f1 (LTS: Long Term Support releases):
• Download+Install: follow this link https://unity3d.com/unity/qa/lts-releases (in China, here is a better link https://unity.cn/releases/lts/2021, 2022.3.17f1c1 would be just fine), scroll down to find our version and install.
• Modules to install:
• IDE: I will be using Visual Studio Code (VSC). You are free to use anything IDE you like, the default IDE for Unity is Microsoft Visual Studio Community, which works very well also.
• WebGL Build Support: Please make sure to install this module for our playtesting (for part-2 of this class will be based on WebGL builds. Additionally, if you are running on a Mac, please also install Windows Build Support such that you can build for PC EXE and the TA can run your assignment submissions.
• Documentation: I would advice installing this as well.

Debugging

• VSC Debugger from Unity has been deprecated. I use Debug.Log() (like cout) for debugging.
• Here is the official documentation on debugging with C#.

Problems Q&A

• WebGL build configuration
• When trying to run your web-GL build, if you encounter this error:
  
• This new setting solved the problem form me. Take a look at this discussion. Before building, click Player Settings on the pop-up window, click on Player and under Publishing Settings look for Compression Format, set this to Disabled as indicated in the following:
  
  
  
• Missing Unity API Intellicence: there may be a few things that are wrong:
• Default editor setting: Edit->Preferences->External Tools->External Script Editor, make sure this is set to your default IDE.
• First time opening the project: Assets->Open C# Project
• Visual Studio Code: if you are using VSC, make sure to install the Unity extension from Microsoft
  
  
• UI option missing from create manu: You need to add the UnityEngine.UI package (Windows->PackageManager [Packages: Unity Registry], search for Unity UI
