unity建房子脚本

以下是一个简单的 Unity 建房子脚本示例，用于创建一个基本的房屋模型：

using UnityEngine;

public class HouseBuilder : MonoBehaviour
{
    public GameObject wallPrefab;       // 墙体预制件
    public GameObject floorPrefab;      // 地面预制件
    public GameObject ceilingPrefab;    // 天花板预制件
    public float wallHeight = 3.0f;     // 墙体高度
    public float roomWidth = 10.0f;     // 房间宽度
    public float roomDepth = 10.0f;     // 房间深度

    void Start()
    {
        BuildHouse();
    }

    void BuildHouse()
    {
        // 创建墙体
        GameObject leftWall = Instantiate(wallPrefab, transform.position, Quaternion.identity);
        leftWall.transform.localScale = new Vector3(1, wallHeight, roomDepth);
        leftWall.transform.position += new Vector3(-roomWidth / 2, wallHeight / 2, 0);

        GameObject rightWall = Instantiate(wallPrefab, transform.position, Quaternion.identity);
        rightWall.transform.localScale = new Vector3(1, wallHeight, roomDepth);
        rightWall.transform.position += new Vector3(roomWidth / 2, wallHeight / 2, 0);

        GameObject backWall = Instantiate(wallPrefab, transform.position, Quaternion.identity);
        backWall.transform.localScale = new Vector3(roomWidth, wallHeight, 1);
        backWall.transform.position += new Vector3(0, wallHeight / 2, -roomDepth / 2);

        GameObject frontWall = Instantiate(wallPrefab, transform.position, Quaternion.identity);
        frontWall.transform.localScale = new Vector3(roomWidth, wallHeight, 1);
        frontWall.transform.position += new Vector3(0, wallHeight / 2, roomDepth / 2);

        // 创建地面
        GameObject floor = Instantiate(floorPrefab, transform.position, Quaternion.identity);
        floor.transform.localScale = new Vector3(roomWidth, 1, roomDepth);
        floor.transform.position += new Vector3(0, -0.5f, 0);

        // 创建天花板
        GameObject ceiling = Instantiate(ceilingPrefab, transform.position, Quaternion.identity);
        ceiling.transform.localScale = new Vector3(roomWidth, 1, roomDepth);
        ceiling.transform.position += new Vector3(0, wallHeight - 0.5f, 0);
    }
}

这个脚本可以创建一个简单的房屋模型，包括四面墙体、地面和天花板。你可以将该脚本附加到一个空的 GameObject 上，并在 Inspector 窗口中设置墙体、地面和天花板的预制件，以及房间宽度、深度和墙体高度等属性。

需要注意的是，这只是一个简单的示例脚本，你可以根据自己的需求进行修改和扩展。如果你想要创建更复杂的房屋模型，需要使用更高级的建模工具和脚本来实现。
