我的统一项目中有一个文件夹,位于“Resources/ScriptableObjects/Skins”下。我需要获取文件夹中的所有对象,为索引生成一个随机数,然后将精灵分配给脚本附加到的现有游戏对象。我得到的当前错误是第 151 行的“NullReferenceException:对象引用未设置为对象的实例”,但我正在第 149 行创建对象的实例。什么给出了?这是我将文件夹中随机脚本对象中的精灵分配给脚本所绑定的游戏对象的函数:
void AssignRandomSkin(){
// Load all skins into memory
Object[] skinObjects = Resources.LoadAll("ScriptableObjects/Skins");
// Get length of list
int amountOfSkins = skinObjects.Length;
// Get random index of skin to assign
int skinToAssignIndex = Random.Range(0, amountOfSkins);
GameObject thisSkin = Instantiate(skinObjects[skinToAssignIndex]) as GameObject;
// Assign it to game object
gameObject.GetComponent<SpriteRenderer>().sprite = thisSkin.GetComponent<Sprite>();
}
这是可编写脚本的对象:
using UnityEngine;
[CreateAssetMenu(fileName = "Skin", menuName = "ScriptableObjects/SkinObject", order = 1)]
public class SkinObject : ScriptableObject
{
public string spriteName; // Name of sprite
public Sprite sprite;
public float xPos;
public float yPos;
public float zPos;
public float xScale;
public float yScale;
public float zScale;
public float fallSpeed; //AKA Weight
public string tier; //Category that skin can be assigned in
}
