# Rect
|
|
|
|
浮点矩形结构体，用于 2D 区域表示。
|
|
|
|
**头文件：** `#include <XCEngine/Core/Math/Rect.h>`
|
|
|
|
**命名空间：** `XCEngine::Math`
|
|
|
|
## 结构体定义
|
|
|
|
```cpp
|
|
struct Rect {
|
|
float x = 0.0f; // 左边界
|
|
float y = 0.0f; // 上边界
|
|
float width = 0.0f;
|
|
float height = 0.0f;
|
|
|
|
Rect() = default;
|
|
Rect(float x, float y, float w, float h) : x(x), y(y), width(w), height(h) {}
|
|
};
|
|
```
|
|
|
|
## 构造函数
|
|
|
|
| 方法 | 描述 |
|
|
|------|------|
|
|
| `Rect()` | 默认构造，初始化为零 |
|
|
| `Rect(x, y, w, h)` | 从坐标和尺寸构造 |
|
|
|
|
## 边界访问
|
|
|
|
| 方法 | 返回值 | 描述 |
|
|
|------|--------|------|
|
|
| [GetLeft()](getleft.md) | `float` | 左边界 (x) |
|
|
| [GetRight()](getright.md) | `float` | 右边界 (x + width) |
|
|
| [GetTop()](gettop.md) | `float` | 上边界 (y) |
|
|
| [GetBottom()](getbottom.md) | `float` | 下边界 (y + height) |
|
|
| [GetPosition()](getposition.md) | `Vector2` | 左上角位置 (x, y) |
|
|
| [GetSize()](getsize.md) | `Vector2` | 尺寸 (width, height) |
|
|
| [GetCenter()](getcenter.md) | `Vector2` | 中心点 |
|
|
|
|
## 检测方法
|
|
|
|
| 方法 | 返回值 | 描述 |
|
|
|------|--------|------|
|
|
| [Contains(px, py)](contains-float.md) | `bool` | 浮点坐标点检测 |
|
|
| [Contains(point)](contains-vector2.md) | `bool` | Vector2 点检测 |
|
|
| [Intersects(other)](intersects.md) | `bool` | 与另一矩形相交 |
|
|
|
|
## 静态方法
|
|
|
|
| 方法 | 返回值 | 描述 |
|
|

|
|
| [Intersect(a, b)](intersect.md) | `Rect` | 两矩形交集 |
|
|
| [Union(a, b)](union.md) | `Rect` | 两矩形并集 |
|
|
|
|
## 设置方法
|
|
|
|
| 方法 | 返回值 | 描述 |
|
|
|------|--------|------|
|
|
| [Set(x, y, w, h)](set.md) | `void` | 设置所有值 |
|
|
| [SetPosition(x, y)](setposition-float.md) | `void` | 设置位置 |
|
|
| [SetPosition(position)](setposition-vector2.md) | `void` | 设置位置 |
