Unity的C#中的数组错误
本文关键字：错误 数组 Unity | 更新日期: 2023-09-27 17:59:06
大家好，我正试图在C#中为unity制作一个库存列表，但当我拿起我的物品时遇到了一个数组错误，我不明白为什么我想知道是否有人能帮忙。我到处寻找一些提示，但没有遇到任何错误是：-
ArgumentException：目标数组不够长。检查destIndex和长度，以及数组的下限
作为编辑iv附上完整的代码
附在下面的代码：-
using UnityEngine;
using System.Collections;
[AddComponentMenu ("Inventory/Inventory")]
public class Inventory : MonoBehaviour {
//This is the central piece of the Inventory System.
public Transform[] Contents; //The content of the Inventory
public int MaxContent = 12; //The maximum number of items the Player can carry.
bool DebugMode = true; //If this is turned on the Inventory script will output the base of what it's doing to the Console window.
private InventoryDisplay playersInvDisplay; //Keep track of the InventoryDisplay script.
public Transform itemHolderObject; //The object the unactive items are going to be parented to. In most cases this is going to be the Inventory object itself.
//Handle components and assign the itemHolderObject.
void Awake (){
itemHolderObject = gameObject.transform;
playersInvDisplay = GetComponent<InventoryDisplay>();
if (playersInvDisplay == null)
{
Debug.LogError("No Inventory Display script was found on " + transform.name + " but an Inventory script was.");
Debug.LogError("Unless a Inventory Display script is added the Inventory won't show. Add it to the same gameobject as the Inventory for maximum performance");
}
}
//Add an item to the inventory.
public void AddItem ( Transform Item ){
ArrayList newContents = new ArrayList();
//FIXME_VAR_TYPE newContents= new Array(Contents);
newContents.Add(Item);
//Contents=newContents.ToBuiltin(Transform); //Array to unity builtin array
newContents.CopyTo(Contents); //Array to unity builtin array
System.Array.Resize(ref Contents, 1);
if (DebugMode)
{
Debug.Log(Item.name+" has been added to inventroy");
}
//Tell the InventoryDisplay to update the list.
if (playersInvDisplay != null)
{
playersInvDisplay.UpdateInventoryList();
}
}
//Removed an item from the inventory (IT DOESN'T DROP IT).
public void RemoveItem ( Transform Item ){
ArrayList newContents = new ArrayList();
//FIXME_VAR_TYPE newContents=new Array(Contents); //!!!!//
int index = 0;
bool shouldend = false;
foreach(Transform i in newContents) //Loop through the Items in the Inventory:
{
if(i == Item) //When a match is found, remove the Item.
{
newContents.RemoveAt(index);
shouldend=true;
//No need to continue running through the loop since we found our item.
}
index++;
if(shouldend) //Exit the loop
{
//Contents=newContents.ToBuiltin(Transform); //!!!!//
Contents=newContents.ToArray(typeof (Transform)) as Transform[];
if (DebugMode)
{
Debug.Log(Item.name+" has been removed from inventroy");
}
if (playersInvDisplay != null)
{
playersInvDisplay.UpdateInventoryList();
}
return;
}
}
}
//Dropping an Item from the Inventory
public void DropItem (Item item){
gameObject.SendMessage ("PlayDropItemSound", SendMessageOptions.DontRequireReceiver); //Play sound
bool makeDuplicate = false;
if (item.stack == 1) //Drop item
{
RemoveItem(item.transform);
}
else //Drop from stack
{
item.stack -= 1;
makeDuplicate = true;
}
item.DropMeFromThePlayer(makeDuplicate); //Calling the drop function + telling it if the object is stacked or not.
if (DebugMode)
{
Debug.Log(item.name + " has been dropped");
}
}
//This will tell you everything that is in the inventory.
void DebugInfo (){
Debug.Log("Inventory Debug - Contents");
int items=0;
foreach(Transform i in Contents){
items++;
Debug.Log(i.name);
}
Debug.Log("Inventory contains "+items+" Item(s)");
}
//Drawing an 'S' in the scene view on top of the object the Inventory is attached to stay organized.
void OnDrawGizmos (){
Gizmos.DrawIcon (new Vector3(transform.position.x, transform.position.y + 2.3f, transform.position.z), "InventoryGizmo.png", true);
}
}
希望有人能提前帮上忙谢谢你：）
当数组被分配时，它们的大小是固定的——只有模拟数组交互的复杂类型才具有自动增长功能。
检查要复制原始数组内容的目标数组的容量。
我不确定ToBuiltIn方法的作用，但它必须创建一个新数组作为原始数组的副本（顺便说一句，您的数据可能已经在数组中了，请通过调试进行检查），其容量设置为数组中的项目总数，可以是1或0。
检查变量并调试代码以查看数组的长度和容量。
更新（根据更新的代码）
调用Add Item方法时，Contents数组未初始化。
为了清楚起见，我已经重写了你粘贴的代码，我没有你使用的所有类，所以我没有测试或检查它的构建，但它会让你知道你能做什么。如果你使用泛型列表，你的数组管理可以简化。
