This demo shows how to create a custom Editor (or Inspector) for your component in Unity. It rapidly covers a number of concepts, from Serialized Objects to Undo and Redo. (Voice generated using Eleven Labs AI technology.)
In the demo, many custom inspector GUIs are created for a component that distributes objects within a radius. Changes to important data (SerializedProperties) are tracked correctly, which causes the component to be marked as dirty. Updates to serialized properties are properly tracked against paste, reset, revert, and other complicated operations.
This video also presents the open source "BetterEditor" library and demonstrates its value

(The library contains the demo scene, components, and all code shown in the video, and it's got tons of comments which expand and explain concepts in the video!)
