# TextMeshPro With AssetBundle
TextMeshPro加载AssetBundle字体测试

TextMeshPro字体默认放在`Resources`相对目录，由于字体有热更的需求，此工程字体打包成AssetBundle测试TextMeshPro能否加载

发现`TMP_Text.cs`是留有自定义加载fontAsset和spriteAsset接口的:
```c#
// *** Unity Event Handling ***

/// <summary>
/// Event delegate to allow custom loading of TMP_FontAsset when using the <font="Font Asset Name"> tag.
/// </summary>
public static event Func<int, string, TMP_FontAsset> OnFontAssetRequest;

/// <summary>
/// Event delegate to allow custom loading of TMP_SpriteAsset when using the <sprite="Sprite Asset Name"> tag.
/// </summary>
public static event Func<int, string, TMP_SpriteAsset> OnSpriteAssetRequest;

/// <summary>
/// Event delegate to allow modifying the text geometry before it is uploaded to the mesh and rendered.
/// </summary>
public virtual event Action<TMP_TextInfo> OnPreRenderText = delegate { };
```
`<font>、<sprite>`这两个标签字体可以通过上面两个事件委托处理

```c#
...
TMP_Text.OnFontAssetRequest += TMP_Text_OnFontAssetRequest;
TMP_Text.OnSpriteAssetRequest += TMP_Text_OnSpriteAssetRequest;
...
private TMP_FontAsset TMP_Text_OnFontAssetRequest(int fontHashCode, string fontAssetName)
{
    throw new System.NotImplementedException();
}

private TMP_SpriteAsset TMP_Text_OnSpriteAssetRequest(int fontHashCode, string spriteAssetName)
{
    throw new System.NotImplementedException();
}
```
# 注意事项
1. 使用`Fallback Sprite Assets`时需要使用`<sprite name="spriteName">`,此时标签`<sprite index=1>`无效
