Code Upgrader Plugin

Code Upgrader is a tool designed to help upgrade your GDScript code from Godot 3 to Godot 4. This plugin automates the process of updating deprecated methods, properties, and syntax, ensuring your projects are compatible with the latest version of Godot.

Notice

This plugin is a work-in-progress tool.

Please know that I might not have picked up all the changes, as there are a lot, so if you find ones that I haven’t added, you can let me know and I will implement those fixes into the plugin!

Next Steps

• Do more focused testing on all the individual Nodes, especially for the TileMapLayer node, to see where I can add more conversions.
• Continuously test the updated functions with a variety of code snippets to ensure that all transformations are applied correctly and do not interfere with each other or modify unintended parts of the code.
• Optimize the performance, especially if applied to large bodies of code, and optimize or refactor as necessary to ensure efficiency.

Usage Instructions

• Download the plugin and enable it.
• If enabled correctly, there should be a new dock on the left side of the editor.
• This dock has two parts: a code input and an output panel.
• We will paste our Godot 3 code in the input panel, and copy our Godot 4 code from the output panel.
• Press execute and your code should be converted!
