EditorWindow.autoRepaintOnSceneChange

설명

Does the window automatically repaint whenever the Scene has changed?

Editor Window that renders what the main camera is "seeing".

// Simple script that lets you render the main camera in an editor Window.

using UnityEngine;
using UnityEditor;

public class CameraViewer : EditorWindow
{
    Camera camera;
    RenderTexture renderTexture;

    [MenuItem("Example/Camera viewer")]
    static void Init()
    {
        EditorWindow editorWindow = GetWindow(typeof(CameraViewer));
        editorWindow.autoRepaintOnSceneChange = true;
        editorWindow.Show();
    }

    public void Awake()
    {
        renderTexture = new RenderTexture((int)position.width,
            (int)position.height,
            (int)RenderTextureFormat.ARGB32);
    }

    public void OnEnable()
    {
        camera = Camera.main;
    }

    public void Update()
    {
        if (camera != null)
        {
            camera.targetTexture = renderTexture;
            camera.Render();
            camera.targetTexture = null;
        }
        if (renderTexture.width != position.width ||
            renderTexture.height != position.height)
            renderTexture = new RenderTexture((int)position.width,
                (int)position.height,
                (int)RenderTextureFormat.ARGB32);
    }

    void OnGUI()
    {
        GUI.DrawTexture(new Rect(0.0f, 0.0f, position.width, position.height), renderTexture);
    }
}
