# Vector2::MoveTowards
```cpp
static Vector2 MoveTowards(const Vector2& current, const Vector2& target, float maxDistance)
```
将当前向量朝目标向量移动指定距离。如果当前向量与目标向量的距离已小于 maxDistance则直接返回目标向量。
**参数:**
- `current` - 当前向量
- `target` - 目标向量
- `maxDistance` - 最大移动距离
**返回:** `Vector2` - 移动后的位置
**线程安全:**
**异常:** (无)
**复杂度:** O(1)
**示例:**
```cpp
Vector2 current(0.0f, 0.0f);
Vector2 target(10.0f, 0.0f);
Vector2 moved = Vector2::MoveTowards(current, target, 3.0f); // (3.0f, 0.0f)
```
