Unity3D中无地形瓦片长远尾场景构建指南

在Unity3D中， 构建一个无地形瓦片的长远尾场景，能让你的游戏或应用拥有更加独特的视觉效果。

1. 删除默认地形瓦片

先说说你需要删除场景中的默认地形瓦片。在Unity编辑器中，右键点击层级面板中的地形，选择“Delete”即可。

2. 创建自定义地形

删除默认地形瓦片后你需要创建一个自定义的地形。这能通过编写代码来实现。

using UnityEngine;
public class CreateTerrain : MonoBehaviour {
    public Material material;
    void Start {
        // 创建 Terrain 数据
        TerrainData terrainData = new TerrainData;
        terrainData.size = new Vector3;
        int resolution = 256;
        terrainData.heightmapResolution = resolution;
        terrainData.alphamapResolution = resolution - 1;
        terrainData.SetDetailResolution;
        terrainData.baseMapResolution = resolution - 1;
        // 创建 Terrain GameObject
        Terrain terrain = Terrain.CreateTerrainGameObject.GetComponent;
        terrain.materialTemplate = material;
        terrain.gameObject.name = "MyTerrain";
        terrain.transform.position = Vector3.zero;
    }
}

3. 添加纹理和植被

为了使地形看起来更加天然你能为地形添加纹理和植被。

using UnityEngine;
public class AddTexture : MonoBehaviour {
    public Texture2D splatmap;
    public Texture2D textures;
    void Start {
        Terrain terrain = GetComponent;
        // 设置 Splatmap
        terrain.terrainData.splatPrototypes = new SplatPrototype;
        for  {
            terrain.terrainData.splatPrototypes = new SplatPrototype;
            terrain.terrainData.splatPrototypes.texture = textures;
        }
        float splatmapData = new float;
        for  {
            for  {
                Color splat = splatmap.GetPixel;
                for  {
                    if  {
                        splatmapData = 1f;
                    }
                }
            }
        }
        terrain.terrainData.SetAlphamaps;
        // 添加植被
        DetailPrototype detailPrototypes = new DetailPrototype;
        for  {
            detailPrototypes = new DetailPrototype;
            detailPrototypes.prototypeTexture = textures;
            detailPrototypes.renderMode = DetailRenderMode.GrassBillboard;
        }
        terrain.terrainData.detailPrototypes = detailPrototypes;
        for  {
            int detailMap = new int;
            for  {
                for  {
                    detailMap = Random.Range;
                }
            }
            terrain.terrainData.SetDetailLayer;
        }
    }
}

4. 自动删除地形瓦片

如果你希望在场景启动时自动删除地形瓦片，能用以下代码：

void Start {
    Terrain terrain = GameObject.FindObjectOfType;
    DestroyImmediate;
}

这些个观点。
