# Quaternion::LookRotation
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
static Quaternion LookRotation(const Vector3& forward, const Vector3& up = Vector3::Up());
|
||
|
|
```
|
||
|
|
|
||
|
|
创建使 forward 方向朝向目标的旋转四元数。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `forward` - 前向方向（会被归一化）
|
||
|
|
- `up` - 向上方向，默认为 Y 轴正方向
|
||
|
|
|
||
|
|
**返回：** 使 forward 朝向目标的旋转四元数
|
