- Type: Enum
- Namespace: UnityEngine
- Assembly: UnityEngine.TerrainModule
[Flags]public enum TerrainChangedFlags
Remarks
Use bitwise AND to detect multiple changes.
using UnityEngine;[ExecuteInEditMode]public class DetectTerrainChanges : MonoBehaviour{ void OnTerrainChanged(TerrainChangedFlags flags) { if ((flags & TerrainChangedFlags.Heightmap) != 0) { Debug.Log("Heightmap changes"); } if ((flags & TerrainChangedFlags.DelayedHeightmapUpdate) != 0) { Debug.Log("Heightmap painting"); } if ((flags & TerrainChangedFlags.TreeInstances) != 0) { Debug.Log("Tree changes"); } }}
The above example shows how you can detect terrain changes by using OnTerrainChanged callback and TerrainChangedFlags enum.
