Question

我正在制作一个spawner脚本，但遇到一个我无法找到解决方案的问题...

我收到错误消息

＆＃34;无法隐式转换类型＆＃39; UnityEngine.Vector3＆＃39;到UnityEngine.Transform＆＃39;＆＃34;

我可以通过向public GameObject[] spawningObj; public GameObject[] insects; public GameObject[] invierment; public GameObject[] inviermentSingel; public Transform player; public int maxNPCsPerChunk; public int maxInectsPerChunk; public int maxInviermentalsPerChunk; public int spawningAria; private Transform spawningpos; // Use this for initialization void Start() { if (player == null) player = GameObject.FindWithTag("Player").transform; int max = Random.Range(0, maxInectsPerChunk); for (int i = 0; i < max; i++) { spawningpos = new Vector3(Random.Range(-spawningAria, spawningAria) + transform.position.x, 2f, Random.Range(-spawningAria, spawningAria) + transform.position.z); //Error on above line Instantiate(insects[Random.Range(0, insects.Length)], spawningpos); }添加.position来删除错误，但这不会起作用，因为它不是对象的变换只是脚本中的变换变量

SELECT prod
FROM yourTable
GROUP BY prod
HAVING SUM(CASE WHEN catid = 1 THEN 1 ELSE 0 END) > 0 AND
       SUM(CASE WHEN catid = 2 THEN 1 ELSE 0 END) > 0 AND
       SUM(CASE WHEN catid = 3 THEN 1 ELSE 0 END) > 0 AND
       SUM(CASE WHEN catid = 4 THEN 1 ELSE 0 END) > 0 AND
       SUM(CASE WHEN catid = 5 THEN 1 ELSE 0 END) > 0

Answer 1

您收到的错误很好地解释了您的问题，让我们一起来看看

＆＃34;无法隐式转换类型＆＃39; UnityEngine.Vector3＆＃39;到UnityEngine.Transform＆＃39;＆＃34;

那你在哪里尝试将Transform的值设置为Vector3？

private Transform spawningpos;

spawningpos是转换

spawningpos = new Vector3(Random.Range(-spawningAria, spawningAria) + transform.position.x, 2f, Random.Range(-spawningAria, spawningAria) + transform.position.z);

但是你明确将其值设置为Vector3

Instantiate(insects[Random.Range(0, insects.Length)], spawningpos);

然后在这一行上实例化对象 - 使用Transform作为输入。正如您将找到here，您正在使用该方法的重载实际上是要求父转换，请尝试此操作

private Vector3 spawningpos;

跟随之前一样

spawningpos = new Vector3(Random.Range(-spawningAria, spawningAria) + transform.position.x, 2f, Random.Range(-spawningAria, spawningAria) + transform.position.z);

最后

Instantiate(insects[Random.Range(0, insects.Length)], spawningpos, Quaternion.identity);

此代码将调用Instantiate方法的正确重载，在传递Vector3时必须设置对象的旋转

Answer 2

您不能直接将 Vector3 对象转换为 Transform。我找到了一个简单的方法。

首先在场景中创建一个 spawnPosition - 一个空的游戏对象。
将变换位置设置为 (0,0,0)
向位置添加随机值。
使用 spawnPosition 的变换。

试试我下面的演示代码，

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CubeSpawner : MonoBehaviour {
    [SerializeField] GameObject cube;
    [SerializeField] Transform spawnTransform;

    // Start is called before the first frame update
    void Start() {
        InvokeRepeating("SpawnCubes", 2, 0.5f);
    }

    // Update is called once per frame
    void Update(){
    }

    void SpawnCubes() {
        spawnTransform.position = new Vector3 (Random.Range (0f, 10f), 18f, 0f);
        GameObject cube1 =Instantiate(cube, spawnTransform) as GameObject;
    }
}

将vector3转换为变换
