ssdfasd b414bc5326 refactor(docs): Fix broken links across multiple modules
Fixed broken references:
- texture-import-settings: Fix 16 files referencing wrong overview filename
- math/rectint: Fix 9 method links (rectint-* → get*, contains, intersects)
- rhi/opengl/device: Fix 8 cross-references (opengl-* → */**)
- resources/mesh: Fix meshsection and vertexattribute links
- rhi/d3d12/sampler: Fix RHISampler reference path
- math/vector3: Fix projectonplane → project-on-plane
- rhi/opengl/command-list: Remove broken ClearFlag enum ref
- rhi/opengl/device: Create 2 new method docs (MakeContextCurrent, GetNativeContext)
- rhi/device: Fix device-info types reference

All 0 broken references remaining.

RectInt

整数矩形结构体,用于像素级 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

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
