# Vector2::Lerp
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
static Vector2 Lerp(const Vector2& a, const Vector2& b, float t)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
在线性插值两个向量之间。参数 t 会在 [0, 1] 范围内被限制。
|
|||
|
|
|
|||
|
|
**参数：**
|
|||
|
|
- `a` - 起始向量
|
|||
|
|
- `b` - 结束向量
|
|||
|
|
- `t` - 插值因子，0 返回 a，1 返回 b
|
|||
|
|
|
|||
|
|
**返回：** `Vector2` - 插值结果
|
|||
|
|
|
|||
|
|
**复杂度：** O(1)
|
|||
|
|
|
|||
|
|
**示例：**
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
Vector2 start(0.0f, 0.0f);
|
|||
|
|
Vector2 end(10.0f, 10.0f);
|
|||
|
|
Vector2 mid = Vector2::Lerp(start, end, 0.5f); // (5.0f, 5.0f)
|
|||
|
|
```
