Question

“ assets / resource / mat”中有一些图像。我想获取此图像并将其放置到array中。但是当我尝试获取这些图像时，我得到了ArrayIndexOutOfBoundsException。我认为Resource.LoadAll（“ mat”）方法存在问题。但是我无法解决。请帮助我

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

public class test : MonoBehaviour
{
    private string t;
    public Sprite[] Icons;

    void Start()
    {
        Object[] loadedIcons = Resources.LoadAll("mat");
        Icons = new Sprite[loadedIcons.Length];

        for (int x = 0; x < loadedIcons.Length; x++)
        { 
            Icons[x] = (Sprite)loadedIcons[x];
            Debug.Log("Loading....");
        }

         GameObject sp = new GameObject();
         sp.GetComponent<SpriteRenderer>().sprite = Icons[0];
    }
}

Answer 1

使用LINQ从特定文件夹加载所有图像看起来像这样...

using UnityEngine;
using System.Linq;

public class Four : MonoBehaviour
{    
    public Sprite[] icons;

    void Start()
    {
        icons= Resources.LoadAll("met", typeof(Sprite)).Cast<Sprite>().ToArray();
    }
}

我不确定，但是我想您不是必须先加载Sprite而不是Texture2D，然后再从中创建一个Sprite。

还请注意，您在新创建的空GameObject上使用了GetComponent<SpriteRenderer>()，因此显然不会附加任何SpriteRenderer组件。而是使用AddComponent。

Sprite[] Icons;
Texture2D LoadedTextures;

private void Start()
{
    LoadedTextures = (Texture2D[])Resources.LoadAll("mat", typeof(Texture2D));
    Icons = new Sprite[loadedIcons.Length];

    for (int x = 0; x < loadedIcons.Length; x++)
    { 
        Icons[x] = Sprite.Create(
            LoadedTextures[x], 
            new Rect(0.0f, 0.0f, LoadedTextures[x].width, LoadedTextures[x].height), 
            new Vector2(0.5f, 0.5f), 
            100.0f);
    }

     GameObject sp = new GameObject();

     // Note that here you created a new empty GameObject
     // so it obviously won't have any component of type SpriteRenderer
     // so add it instead of GetComponent
     sp.AddComponent<SpriteRenderer>().sprite = Icons[0];
}
