# UIExtension UXDraggable 拖拽模块手册

## 模块概述
`UXDraggable` 把拖拽生命周期包装为 `UnityEvent<PointerEventData>`，便于直接在 Inspector 或代码中订阅。

## 可调用 API
源码：`Packages/com.alicizax.unity.ui.extension/Runtime/UXComponent/Drag/UXDraggable.cs`
- `onDrag`
- `onBeginDrag`
- `onEndDrag`

## 快速上手
```csharp
var draggable = gameObject.AddComponent<UnityEngine.UI.UXDraggable>();
draggable.onBeginDrag.AddListener(_ => UnityEngine.Debug.Log("Begin"));
```
