Unity学习第三篇之实现Resources资源加载模块

首先先定义ILoader基类

using System;

public interface ILoader
{
GameObject LoadPrefab(string path);
GameObject LoadPrefabAndInstantiate(string path, Transform parent = null);
void LoadConfig(string path, Action<object> complete);
T Load<T>(string path) where T : Object;
T[] LoadAll<T>(string path) where T : Object;
}

继承自ILoader 的 Resources资源加载类

using System.Collections;
using UnityEngine;
using Object = UnityEngine.Object;

public class ResourceLoader : ILoader
{
public GameObject LoadPrefab(string path)
{
var prefab = Resources.Load<GameObject>(path);

return prefab;
}

public GameObject LoadPrefabAndInstantiate(string path, Transform parent = null)
{
var prefab = LoadPrefab(path);
var temp = Object.Instantiate(prefab, parent);
return temp;
}

public T Load<T>(string path) where T : Object
{
var sprite = Resources.Load<T>(path);
if (sprite == null)
{
Debug.LogError("未找到对应图片，路径：" + path);
return null;
}

return sprite;
}

public T[] LoadAll<T>(string path) where T : Object
{
var sprites = Resources.LoadAll<T>(path);
if (sprites == null || sprites.Length == 0)
{
Debug.LogError("当前路径下未找到对应资源，路径：" + path);
return null;
}

return sprites;
}

public void LoadConfig(string path, Action<object> complete)
{
CoroutineMgr.Single.ExecuteOnce(Config(path, complete));
}

private IEnumerator Config(string path, Action<object> complete)
{
if (Application.platform != RuntimePlatform.Android)
path = "file://" + path;

var www = new WWW(path);
yield return www;

if (www.error != null)
{
Debug.LogError("加载配置错误，路径为：" + path);
yield break;
}

complete(www.text);
Debug.Log("文件加载成功，路径为：" + path);
}
}

继承自ILoader 的AB包资源加载方式

public class ABLoader : ILoader
{
public GameObject LoadPrefab(string path)
{
throw new NotImplementedException();
}

public GameObject LoadPrefabAndInstantiate(string path, Transform parent = null)
{
throw new NotImplementedException();
}

public void LoadConfig(string path, Action<object> complete)
{
throw new NotImplementedException();
}

public T Load<T>(string path) where T : Object
{
throw new NotImplementedException();
}

public T[] LoadAll<T>(string path) where T : Object
{
throw new NotImplementedException();
}
}

LoadMgr 管理类，外部只需要调用管理类

}

public GameObject LoadPrefab(string path)
{
return _loader.LoadPrefab(path);
}

public GameObject LoadPrefabAndInstantiate(string path, Transform parent = null)
{
return _loader.LoadPrefabAndInstantiate(path, parent);
}

public void LoadConfig(string path, Action<object> complete)
{
_loader.LoadConfig(path, complete);
}

public T Load<T>(string path) where T : Object
{
return _loader.Load<T>(path);
}

public T[] LoadAll<T>(string path) where T : Object
{
return _loader.LoadAll<T>(path);
}
}
