如何在Raylib中隐藏图形？

#include "raylib.h"

int main()
{
    InitWindow(800, 600, "Hide Graphics Example");
    
    // 其他代码
    
    CloseWindow();
    
    return 0;
}

while (!WindowShouldClose())
{
    BeginDrawing();
    
    ClearBackground(RAYWHITE);
    
    // 绘制图形
    
    EndDrawing();
}

Rectangle rect = { 100, 100, 200, 200 };
bool isHidden = false;

while (!WindowShouldClose())
{
    BeginDrawing();
    
    ClearBackground(RAYWHITE);
    
    if (!isHidden)
    {
        DrawRectangleRec(rect, RED);
    }
    
    EndDrawing();
    
    if (IsKeyPressed(KEY_H))
    {
        isHidden = !isHidden;
    }
}
