# 资源加载
|
|
|
|
在加载资源对象的时候只需要提供相对路径，统一约定该相对路径名称为：location
|
|
|
|
加载接口：
|
|
|
|
- YooAssets.LoadAssetSync() 同步加载资源对象接口
|
|
- YooAssets.LoadSubAssetsSync() 同步加载子资源对象接口
|
|
- YooAssets.LoadAssetAsync() 异步加载资源对象接口
|
|
- YooAssets.LoadSubAssetsAsync() 异步加载子资源对象接口
|
|
- YooAssets.LoadSceneAsync() 异步加载场景接口
|
|
- YooAssets.LoadRawFileAsync() 异步读取原生文件接口
|
|
|
|
**加载路径的匹配方式**
|
|
|
|
````C#
|
|
// 不带扩展名的模糊匹配
|
|
YooAssets.LoadAssetAsync<AudioClip>("Audio/bgMusic");
|
|
|
|
// 带扩展名的精准匹配
|
|
YooAssets.LoadAssetAsync<AudioClip>("Audio/bgMusic.mp3");
|
|
````
|
|
|
|
**异步加载范例**
|
|
|
|
````C#
|
|
// 委托加载方式
|
|
void Start()
|
|
{
|
|
AssetOperationHandle handle = YooAssets.LoadAssetAsync<AudioClip>("Audio/bgMusic.mp3");
|
|
handle.Completed += Handle_Completed;
|
|
}
|
|
void Handle_Completed(AssetOperationHandle handle)
|
|
{
|
|
AudioClip audioClip = handle.AssetObject as AudioClip;
|
|
}
|
|
````
|
|
````C#
|
|
// 协程加载方式
|
|
IEnumerator Start()
|
|
{
|
|
AssetOperationHandle handle = YooAssets.LoadAssetAsync<AudioClip>("Audio/bgMusic.mp3");
|
|
yield return handle;
|
|
AudioClip audioClip = handle.AssetObject as AudioClip;
|
|
}
|
|
````
|
|
````C#
|
|
// Task加载方式
|
|
async void Start()
|
|
{
|
|
AssetOperationHandle handle = YooAssets.LoadAssetAsync<AudioClip>("Audio/bgMusic.mp3");
|
|
await handle.Task;
|
|
AudioClip audioClip = handle.AssetObject as AudioClip;
|
|
}
|
|

**资源卸载范例**
|
|
|
|
````C#
|
|
IEnumerator Start()
|
|
{
|
|
AssetOperationHandle handle = YooAssets.LoadAssetAsync<AudioClip>("Audio/bgMusic.mp3");
|
|
yield return handle;
|
|
...
|
|
handle.Release();
|
|
}
|
|
````
|
|
|
|
**预制体加载范例**
|
|
|
|
````C#
|
|
IEnumerator Start()
|
|
{
|
|
AssetOperationHandle handle = YooAssets.LoadAssetAsync<GameObject>("Panel/login.prefab");
|
|
yield return handle;
|
|
GameObject go = handle.InstantiateSync();
|
|
Debug.Log($"Prefab name is {go.name}");
|
|
}
|
|
````
|
|
|
|
**子对象加载范例**
|
|
|
|
例如：通过TexturePacker创建的图集，如果需要访问图集的精灵对象，可以通过子对象加载接口。
|
|
|
|
````c#
|
|
IEnumerator Start()
|
|
{
|
|
SubAssetsOperationHandle handle = YooAssets.LoadSubAssetsAsync<Sprite>(location);
|
|
yield return handle;
|
|
var sprite = handle.GetSubAssetObject<Sprite>("spriteName");
|
|
Debug.Log($"Sprite name is {sprite.name}");
|
|
}
|
|
````
|
|
|
|
**场景异步加载范例**
|
|
|
|
````c#
|
|
IEnumerator Start()
|
|
{
|
|
var sceneMode = UnityEngine.SceneManagement.LoadSceneMode.Single;
|
|
bool activateOnLoad = true;
|
|
SceneOperationHandle handle = YooAssets.LoadSceneAsync("Scene/Login", sceneMode, activateOnLoad);
|
|
yield return handle;
|
|
Debug.Log($"Scene name is {handle.Scene.name}");
|
|
}
|
|
````
|
|
|
|
**原生文件加载范例**
|
|
|
|
例如：wwise的初始化文件
|
|
|
|
````c#
|
|
IEnumerator Start()
|
|
{
|
|
string location = "wwise/init.bnk";
|
|
string savePath = $"{Application.persistentDataPath}/Audio/init.bnk";
|
|
RawFileOperation operation = YooAssets.LoadRawFileAsync(location, savePath);
|
|
yield return operation;
|
|
byte[] fileData = operation.GetFileData();
|
|
string fileText = operation.GetFileText();
|
|
}
|
|
````
