TerrainChangedFlags

Description

Indicate the types of changes to the terrain in OnTerrainChanged callback.

Use bitwise AND to detect multiple changes.

@ExecuteInEditMode
public class DetectTerrainChanges extends MonoBehaviour {
	function OnTerrainChanged(flags: TerrainChangedFlags) {
		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");
		}
	}
}

[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.
