+# Vector3::MoveTowards
+
+```cpp
+static Vector3 MoveTowards(const Vector3& current, const Vector3& target, float maxDistance)
+```
+
+将当前向量朝目标向量移动指定距离。如果距离已小于 maxDistance，则直接返回目标。
+
+**参数：**
+- `current` - 当前向量
+- `target` - 目标向量
+- `maxDistance` - 最大移动距离
+
+**返回：** `Vector3` - 移动后的位置
+
+**复杂度：** O(1)
+
+**示例：**
+
+```cpp
+Vector3 current(0.0f, 0.0f, 0.0f);
+Vector3 target(10.0f, 0.0f, 0.0f);
+Vector3 moved = Vector3::MoveTowards(current, target, 3.0f);  // (3.0f, 0, 0)
+```
