Install the ActionScript and MXML extension for Visual Studio Code

Prerequisites

The ActionScript & MXML extension for Visual Studio Code has the following requirements:

• Visual Studio Code
• Java JDK 11 (or newer)

💡 Tip: OpenJDK is available to download for free from a variety of vendors, and many experts now recommend avoiding the JDK version from Oracle. If you’re not sure which JDK vendor to choose, a good option is Temurin OpenJDK from Adoptium.net. All OpenJDK versions should be compatible, but Temurin OpenJDK is typically used when testing the vscode-as3mxml and vscode-swf-debug extensions.

Installation

Run Visual Studio Code, and follow these steps to install the ActionScript & MXML extension:

1. Open the Extensions view.
2. Search for ActionScript.
3. In the results, find the ActionScript & MXML extension by Bowler Hat LLC.
4. Click the Install button.

You may be asked to restart Visual Studio Code, and then you're ready to create your first project.
