分配 2 个向量 SDL_Rect c++ 导致垃圾值

在 Tilemap 类中，我使用矢量 来保存每个 Tilemap 对象的平台位置和大小。在文件 Tilemap_data 中，我声明了我所有的 Tilemap 对象，包括 vector 在 Tilemap 类中，我使用矢量 来保存每个 Tilemap 对象的平台位置和大小。在文件 Tilemap_data 中，我声明了我所有的 Tilemap 对象，包括它们附带的 vector。 我有一个 present_tilemap_pos_x 变量来检查 Tilemap 对象是否在屏幕之外。 在main.cpp中，如果程序运行正常，当正在显示的Tilemap对象（符号为“present_tilemap”）跑出屏幕，下一个Tilemap对象（符号为“next_tilemap”）正在显示时，程序会发生变化，使得present_tilemap 取 next_tilemap 的值，next_tilemap 的数据将从包含 SDL_Rect 对象的向量数组中随机获取。 （在我上面提到的 Tilemap 对象的数据集中）。 然而，虽然为 next_tilemap 分配新值工作正常，但为 present_tilemap 对象分配值是错误的，因为向量 的 x、y 和 h 值分配正确，而 w 值是垃圾值。 我将在这里发布我的代码，为了简化它，我将删除所有与我在问题中提出的问题无关的不相关部分。为了方便起见，我还会提供一个日志文件，记录每次迭代后的程序。 文件 Tilemap.hpp: #pragma once #ifndef Tilemap_hpp #define Tilemap_hpp #include <iostream> #include <vector> #include <SDL2/SDL.h> using namespace std; class Tilemap { private: int tilemap_index; int tilemap[18][32]; int number_of_platform = 0; vector <SDL_Rect> platform_rects; public: Tilemap(); Tilemap(int index, int tilemap[18][32], int number, SDL_Rect platform[]); ~Tilemap(); int get_tilemap_index(); int get_tilemap(int x, int y); void set_tilemap_index(int index); void set_tilemap(int x, int y, int value); int get_number_of_platform(); void set_number_of_platform(int number_of_platform); void set_platform_rects(std::vector <SDL_Rect> platform_rects); std::vector <SDL_Rect> get_platform_rects() { return platform_rects; } vector <SDL_Rect> update_platform_rects(Tilemap& tilemap, int tilemap_pos_x); void create_platform_rects(int x, int y, int width, int height); void update_platform_rects(int tilemap_pos_x); }; #endif /* Tilemap_hpp */ 文件 Tilemap.cpp： #include "Tilemap.hpp" Tilemap::Tilemap() { } Tilemap::Tilemap(int index, int tilemap[18][32], int number, SDL_Rect platform[]) { tilemap_index = index; for (int i = 0; i < 18; i++) { for (int j = 0; j < 32; j++) { this->tilemap[i][j] = tilemap[i][j]; } } number_of_platform = number; for (int i = 0; i < number; i++) { platform_rects.push_back(platform[i]); } } Tilemap::~Tilemap() { } int Tilemap::get_tilemap_index() { return tilemap_index; } int Tilemap::get_tilemap(int x, int y) { return tilemap[x][y]; } void Tilemap::set_tilemap_index(int index) { tilemap_index = index; } void Tilemap::set_tilemap(int x, int y, int value) { tilemap[x][y] = value; } void Tilemap::create_platform_rects(int x, int y, int width, int height) { SDL_Rect platform_rect; platform_rect.x = x; platform_rect.y = y; platform_rect.w = width; platform_rect.h = height; platform_rects.push_back(platform_rect); } void Tilemap::update_platform_rects(int tilemap_pos_x) { // di chuyển các platform sang trái với tốc độ speed for (int i = 0; i < platform_rects.size(); i++) { platform_rects[i].x += tilemap_pos_x; } // xóa các platform ở phía bên trái màn hình while (!platform_rects.empty() && platform_rects[0].x + platform_rects[0].w < 0) { platform_rects.erase(platform_rects.begin()); } } int Tilemap::get_number_of_platform() { return number_of_platform; } void Tilemap::set_number_of_platform(int number_of_platform) { this->number_of_platform = number_of_platform; } void Tilemap::set_platform_rects(std::vector<SDL_Rect> platform_rects) { this->platform_rects = platform_rects; } vector <SDL_Rect> Tilemap::update_platform_rects(Tilemap& tilemap, int tilemap_pos_x) { for (int i = 0; i < platform_rects.size(); i++) { platform_rects[i].x += tilemap_pos_x; } return platform_rects; } 文件 Tilemap_data.hpp： ...
