In order to create VCI script, you need to complete the steps in Installation of VCI development environment and installation of following programs.

• VSCode

Download and install VSCode from VSCode.
VSCode is an open source text editor provided by Microsoft. (Wikipedia)
We will be using this for the creation of VCI script.

Open Visual Studio Marketplace and select Install.
If a dialog appears asking for permission to open in VSCode, select Open.

When VSCode opens, select Install.
This will enable Lua Intellisense.

Before continuing with following steps, import the VCI into Virtual Cast and spawn it at least once.
Following procedure requires the path and the file that are created during the execution of Virtual Cast.

1. Launch VSCode and open the following folder by selecting [File] > [Open Folder…].

C:/Users/__USER_NAME__/AppData/LocalLow/VirtualCast/VirtualCast

2. Open “EmbeddedScriptWorkspace” folder inside the path specified above.
Note: You have to replace the _USER_NAME_ with the User Name set for your computer.

If you could see [Types.lua] and [template.lua] loaded into VSCode, the VCI Intellisense is successfully enabled.
