# 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)
|
|||
|
|
```
