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

资源加载接口：

• 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

加载路径的匹配方式

// 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

// 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;
}

// 协程加载方式
void Start()
{
	this.StartCoroutine(AsyncLoad());
}
IEnumerator AsyncLoad()
{
	AssetOperationHandle handle = YooAssets.LoadAssetAsync<AudioClip>("Audio/bgMusic.mp3");
	yield return handle;   
	AudioClip audioClip = handle.AssetObject as AudioClip;
}

// Task加载方式
async void Start()
{
	await AsyncLoad();
}
async Task AsyncLoad()
{
	AssetOperationHandle handle = YooAssets.LoadAssetAsync<AudioClip>("Audio/bgMusic.mp3");
	await handle.Task;
    AudioClip audioClip = handle.AssetObject as AudioClip;	
}

资源卸载范例

void Start()
{
	AssetOperationHandle handle = YooAssets.LoadAssetAsync<AudioClip>("Audio/bgMusic.mp3");

	...

	handle.Release();
}

预制体同步加载范例

var handle = YooAssets.LoadAssetSync<GameObject>(location);
GameObject go = handle.InstantiateObject;

var handle = YooAssets.LoadAssetSync<GameObject>(location);
GameObject go = UnityEngine.Object.Instantiate(handle.AssetObject as GameObject);

子对象同步加载范例

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。

var handle = YooAssets.LoadSubAssetsSync<Sprite>(location);
foreach (var asset in handle.AllAssets)
{
	Debug.Log($"Sprite name is {asset.name}");
}

场景异步加载范例

void Start()
{
	// 场景加载参数
	SceneInstanceParam param = new SceneInstanceParam();
	param.LoadMode = UnityEngine.SceneManagement.LoadSceneMode.Single;
	param.ActivateOnLoad = true;

	AssetOperationHandle handle = YooAssets.LoadSceneAsync("Scene/Login", param);
	handle.Completed += Handle_Completed;
}
void Handle_Completed(AssetOperationHandle handle)
{
	SceneInstance instance = handle.AssetInstance as SceneInstance;
	Debug.Log(instance.Scene.name);
}
