# Rect::Contains (Vector2)
|
|
|
|
```cpp
|
|
bool Contains(const Vector2& point) const
|
|
```
|
|
|
|
检测 Vector2 点是否在矩形内。
|
|
|
|
**参数：**
|
|
- `point` - 要检测的二维点
|
|
|
|
**返回：** `bool` - 点在矩形内（左上边界包含，右下边界不含）返回 true
|
|
|
|
**复杂度：** O(1)
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
Rect rect(0.0f, 0.0f, 100.0f, 100.0f);
|
|
Vector2 point(50.0f, 50.0f);
|
|
if (rect.Contains(point)) {
|
|
// 点在矩形内
|
|
}
|
|
```
