EditorWindow.CreateGUI()

설명

CreateGUI is called when the EditorWindow's rootVisualElement is ready to be populated.

Use CreateGUI to add UIToolkit user interface elements to your window.

// A simple script that saves frames from the Game view when in Play mode.
// This example is the same as the OnGUI() example, but uses retained-mode UIToolkit UI.
//
// You can put the frames together later to create a video.
// The frames are saved in the project, at the same level of the project hierarchy as the Assets folder.
