Question

嘿伙计们我对团结和编码很新，但我真的试图找出为什么这个脚本不适用。该脚本的想法是应该在X轴上的随机位置上在+9到-9范围内重复产生一个对象，但它只是在对象的起始位置产生一次。希望有人能指出我正确的方向：）

using UnityEngine;
using System.Collections;

public class SpawnOnXaxis : MonoBehaviour {

public GameObject Goodfood;
public int numToSpawn;
public Vector3 position;

void Awake()        
{
    Vector3 position = new Vector3(Random.Range(-9.0F, 9.0F), 10.5f, -1); // -9 på Xaxis - +9 ----- Y = 10.5 z = -1
}

void Start() 
{
    int spawned = 0;

    while (spawned < numToSpawn)
    {

        position = new Vector3(Random.Range(-9.0F, 9.0F), 10.5f, Random.Range(-9.0F, 9.0F));

        GameObject tmp = Instantiate(Goodfood, position, Quaternion.identity) as GameObject; // Quaternion.identity betyder "ingen rotation"

        spawned++;
        System.Threading.Thread.Sleep(500);
    }
}

}

Answer 1

您没有将numToSpawn设置为任何内容。试试这个：

public class SpawnOnXaxis : MonoBehaviour {

public GameObject Goodfood;
public int numToSpawn;
public Vector3 position;

void Awake()        
{
    position = new Vector3(Random.Range(-9.0F, 9.0F), 10.5f, -1); // -9 på Xaxis - +9 ----- Y = 10.5 z = -1
    numToSpawn = 10;
}

void Start() 
{
    int spawned = 0;

    while (spawned < numToSpawn)
    {

        position = new Vector3(Random.Range(-9.0F, 9.0F), 10.5f, Random.Range(-9.0F, 9.0F));

        GameObject tmp = Instantiate(Goodfood, position, Quaternion.identity) as GameObject; // Quaternion.identity betyder "ingen rotation"

        spawned++;
        System.Threading.Thread.Sleep(500);
    }
}
}

试试这个。 Invoke Reapeating可以解决您的问题。下面的代码调用CreateObjects 0.3秒。首先是1秒后开始。

public GameObject Goodfood;
public int numToSpawn;  //I assume you edit this value in editor
public Vector3 position;
int spawned = 0;
void Start() // or you can use Awake too.
{
    InvokeRepeating("CreateObjects", 1, 0.3);
}

void CreateObjects(){
     position = new Vector3(Random.Range(-9.0F, 9.0F), 10.5f, Random.Range(-9.0F, 9.0F));
     GameObject tmp = Instantiate(Goodfood, position, Quaternion.identity) as GameObject;
     spawned++;
     if(spawned>9){
        CancelInvoke("CreateObjects");
     }
}

如果您不想使用此功能，也许您可以使用Update方法。像

 void Update() {
     if(spawned<10){
         position = new Vector3(Random.Range(-9.0F, 9.0F), 10.5f, Random.Range(-9.0F, 9.0F));
         GameObject tmp = Instantiate(Goodfood, position, Quaternion.identity) as GameObject;
         spawned++;
     }
 }

Unity脚本没有做任何事情，但也没有得到任何错误
