OnSceneGUI 관련코드

 

 

 

 

 

OnDrawGizmos처럼 상시동작하는점이 비슷하지만

OnDrawGizmos는 기즈모 드로우 옵션이 켜져있을때에만 동작하므로

기능코드는 가급적 OnSceneGUI에 넣는것이 좋다

 

 

 

1. Static에서 FindObjectsOfType를 이용해 가져와서 처리하는 방식

gist : https://gist.github.com/ahzkwid/3294e9d4cf3980ae2d1c135123db145c

public class SampleClass : MonoBehaviour
{
  static void OnSceneGUI(SceneView sceneView)
  {
      foreach (var sampleClass in FindObjectsOfType<SampleClass>())
      {
          if (sceneView.camera != null)
          {
              var sceneCamera = sceneView.camera;
              //CameraCode
          }
          //otherCode
      }
  }
}

2. SceneView.duringSceneGui에서 이벤트를 받는 방식

아래 코드는 내가 만든게 아니고 위 링크에서 가져와 간소화 한것일뿐이다

[ExecuteInEditMode]
public class SampleClass : MonoBehaviour
{
     void OnEnable()
    {
        SceneView.duringSceneGui += OnSceneGUI;
        EditorApplication.hierarchyWindowItemOnGUI += OnHierarchyGUI;
    }

     void OnDisable()
    {
        SceneView.duringSceneGui -= OnSceneGUI;
        EditorApplication.hierarchyWindowItemOnGUI -= OnHierarchyGUI;
    }
     void OnSceneGUI(SceneView obj)
    {
        HandleDragAndDropEvents();
    }

     void OnHierarchyGUI(int instanceID, Rect selectionRect)
    {
        HandleDragAndDropEvents();
    }
     void HandleDragAndDropEvents()
    {
        if (Event.current.type == EventType.DragUpdated)
        {
            OnDragUpdated();
        }
        if (Event.current.type == EventType.DragPerform)
        {
            OnDragPerform();
        }
    }
    void OnDragUpdated()
    {
        Debug.Log("OnDragUpdated()");
    }
    void OnDragPerform()
    {
        Debug.Log("OnDragPerform()");
    }
}
