- Explore editor scripting libraries like EditorAssetLibrary and EditorUtilityLibrary
- Write Slate code to build custom editor widgets
- Create a custom editor tab for displaying Slate widgets
- Create materials and connect pins through code
- Create custom editor hot keys to trigger custom functions
- Extend the Content Browser Menu Actor Selection Menu, and World Outliner
- Add custom icons as UI elements
✅ Requirements
- Skills: Experience with C++ in Unreal Engine, or at least one Unreal C++ course completed.
📝 Description
This course is all about getting your hands dirty with the Unreal Engine 5 editor. You’ll start by exploring the built-in scripting libraries like UEditorAssetLibrary and UEditorUtilityLibrary to handle quick asset actions. From there, you’ll build custom menu entries that let you search and delete unused assets or clean out empty folders right from the Content Browser context menu.
The real meat comes when you dive into Slate. You’ll learn how to create your own editor tab, populate it with widgets like list views, checkboxes, and buttons, and wire them up to perform real tasks. This isn’t just theory—you’ll build a functional tool that lists unused assets and lets you delete them with a click.
The second half of the course shifts focus to actors. You’ll use EditorActorSubsystem to implement batch selection, duplication, and transform randomization. Then you’ll combine everything you’ve learned to create a selection lock feature, custom hot keys, and even extend the World Outliner with your own columns and buttons.
By the end, you’ll have a solid understanding of how to create custom editor tools that fit your specific workflow. Whether it’s automating material creation from code or adding your own icons to menu entries, you’ll have the skills to make the editor work for you.
