Unity2018定位游戏场景视图到Scene视图工具编写

使用编辑器：

Unity2018.4.2

工具来由

当Unity场景中的物体太多，无法在scene视图定位到游戏中看到的物体时，可以通过使用SceneView对当前视图进行定位

应用举例

using UnityEngine;
#if UNITY_EDITOR
	using UnityEditor;
#endif

public class SyncSceneView : MonoBehaviour
{

#if UNITY_EDITOR
	private SceneView view = null;

	// Use this for initialization
	void Awake()
	{
		view = SceneView.lastActiveSceneView;
		//view.m_RenderMode = DrawCameraMode.Mipmaps;
		SceneView.CameraMode cameraMode = view.cameraMode;
		cameraMode.drawMode = DrawCameraMode.Mipmaps;
	}

	private void LateUpdate()
	{
		if (view != null)
		{
			view.LookAt(transform.position, transform.rotation, 0f);
		}
	}

	private void OnDestroy()
	{
		if (view != null)
		{
			view.LookAt(transform.position, transform.rotation, 5f);
		}
	}

	public void CloseTool()
	{
		//view.m_RenderMode = (DrawCameraMode)0;
		SceneView.CameraMode cameraMode = view.cameraMode;
		cameraMode.drawMode = DrawCameraMode.Textured;
		view = null;
		Destroy(this);
	}
#endif
}
