unity3d教程动态创建简单平面地形

unity3d创建地形是不须要usingUnityEditor的。这里使用了AssetDatabase。所以需using UnityEditor;
创建三步:
1.TerrainData 

terrainData = newTerrainData();
2.设置terrainData的属性
3.依据terrainData创建地形
  GameObject obj =Terrain.CreateTerrainGameObject(terrainData);
详细脚本例如以下:
using UnityEngine;
using System.Collections;
using UnityEditor;

public class Tutor_1_CreateSimpleTerrain : MonoBehaviour {
void Start()
{
CreateTerrain();
}
public Terrain CreateTerrain()
{
TerrainData  terrainData = newTerrainData();
terrainData.heightmapResolution = 513;
terrainData.baseMapResolution = 513;
terrainData.size = new Vector3(50, 50, 50);
terrainData.alphamapResolution = 512;
    terrainData.SetDetailResolution(32, 8);
GameObject obj =Terrain.CreateTerrainGameObject(terrainData);
AssetDatabase.CreateAsset(terrainData,"Assets/Tutorial/Tutor_1_SimpleTerrain.asset");
    AssetDatabase.SaveAssets();
return obj.GetComponent<</span>Terrain>();
}
}
