ssdfasd 63d0271a5b Fix broken links in Math API docs
Fix 30+ broken cross-references in docs/api/math/:
- viewport: viewport-getaspectratio/getrect -> getaspectratio/getrect
- matrix4: ../color/operator-mul -> operator_mul, operator-index -> operator_index
- matrix4/get-*: gettranslation/getscale/getrotation -> get-translation/-scale/-rotation
- vector3 operator links: operator_*_assign -> operator-*-assign
- vector3 operator links: operator_sub/add -> operator-sub/add
- vector3 operator-eq/neq: swap mutual references to use hyphen naming
- vector4: ../plane/constructor-default -> constructor_default
- Linter fixes: aabb and rectint relative paths corrected

RectInt

整数矩形结构体,用于像素级 2D 区域表示。

头文件: #include <XCEngine/Math/Rect.h>

命名空间: XCEngine::Math

结构体定义

struct RectInt {
    int32_t x = 0;
    int32_t y = 0;
    int32_t width = 0;
    int32_t height = 0;

    RectInt() = default;
    RectInt(int32_t x, int32_t y, int32_t w, int32_t h);
};

构造函数

方法 描述
RectInt() 默认构造
RectInt(x, y, w, h) 从整数坐标和尺寸构造

边界访问

方法 返回值 描述
GetLeft() int32_t 左边界
GetRight() int32_t 右边界
GetTop() int32_t 上边界
GetBottom() int32_t 下边界
GetPosition() Vector2 位置(转换为浮点)
GetSize() Vector2 尺寸(转换为浮点)
GetCenter() Vector2 中心点

检测方法

方法 返回值 描述
Contains(px, py) bool 整数坐标点检测
Intersects(other) bool 与另一矩形相交
