[英]Unity 4 C# - IndexOutOfRangeException: Array index is out of range
[英]Unity3d scripting error c# IndexOutOfRangeException: Array index is out of range
這是用c#編寫的我的生成腳本。該腳本應在場景中隨機創建對象。
問題是我在運行時遇到此錯誤。
IndexOutOfRangeException: Array index is out of range.
CreateEasterEggs.MakeThingToSpawn () (at Assets/CreateEasterEggs.cs:52)
CreateEasterEggs.Update () (at Assets/CreateEasterEggs.cs:28)
不確定我做錯了什么,認為與游戲對象有關嗎?
謝謝。
using UnityEngine;
using System.Collections;
public class CreateEasterEggs : MonoBehaviour
{
public float secondsBetweenSpawning = 0.1f;
public float xMinRange = -25.0f;
public float xMaxRange = 25.0f;
public float yMinRange = -5.0f;
public float yMaxRange = 0.0f;
public float zMinRange = -25.0f;
public float zMaxRange = 25.0f;
public GameObject[] spawnObjects; // what prefabs to spawn
private float nextSpawnTime;
void Start ()
{
// determine when to spawn the next object
nextSpawnTime = Time.time+secondsBetweenSpawning;
}
void Update ()
{
// if time to spawn a new game object
if (Time.time >= nextSpawnTime) {
// Spawn the game object through function below
MakeThingToSpawn ();
// determine the next time to spawn the object
nextSpawnTime = Time.time+secondsBetweenSpawning;
}
}
void MakeThingToSpawn ()
{
//Start the vector at an invalid position
Vector3 spawnPosition = new Vector3(0, 0, 0);
//while we are not in the right range, continually regenerate the position
while ((spawnPosition.z < 4 && spawnPosition.z > -4) || (spawnPosition.x < 4 && spawnPosition.x > -4))
{
spawnPosition.x = Random.Range (xMinRange, xMaxRange);
spawnPosition.y = Random.Range (yMinRange, yMaxRange);
spawnPosition.z = Random.Range (zMinRange, zMaxRange);
}
// determine which object to spawn
int objectToSpawn = Random.Range (0, spawnObjects.Length);
// actually spawn the game object
GameObject spawnedObject = Instantiate (spawnObjects [objectToSpawn], spawnPosition, transform.rotation) as GameObject;
// make the parent the spawner so hierarchy doesn't get super messy
spawnedObject.transform.parent = gameObject.transform;
}
}
IndexOutOfRange
表示您嘗試訪問不存在的數組元素。
在您的情況下,使用Random.Range (0, spawnObjects.Length);
那么唯一可能的情況是您的數組為空。
嘗試Debug.Log(spawnObjects.Length):
在Instantiate
之前,您會發現實際上您的游戲對象數組為空,因為它將返回0。
