C++ SFML 2.2矢量

Question

我只是玩C++ SFML的東西，我有點不明白爲什麼我的代碼不工作。我想要做的事情就是讓我們說5，在窗口中使用矢量隨機放置在窗口中的正方形，但我不明白爲什麼它不起作用。

這是主要的遊戲類：

#include "main_game.h" 
#include "main_menu.h" 

void main_game::Initialize(sf::RenderWindow* window) 
{ 
    this->Player = new player(); 
    this->Player->setOrigin(this->Player->getGlobalBounds().width/2, this->Player->getGlobalBounds().height/2); 

    this->TestObject = new testObject(); 
    this->TestObject->Initialize(); 
    this->TestObject->setOrigin(this->TestObject->getGlobalBounds().width/2, this->TestObject->getGlobalBounds().height/2); 
} 

void main_game::Update(sf::RenderWindow* window) 
{ 
    this->Player->setPosition(sf::Mouse::getPosition(*window).x, sf::Mouse::getPosition(*window).y); 
    this->Player->Update(); 

    if (this->Player->CheckCollision(TestObject)) 
    { 
     this->TestObject->setColor(sf::Color::Red); 
    } 
    else 
    { 
     this->TestObject->setColor(sf::Color::Cyan); 
    } 

    if (sf::Keyboard::isKeyPressed(sf::Keyboard::Key::Escape)) 
    { 
     coreState.SetState(new main_menu()); 
    } 
} 

void main_game::Render(sf::RenderWindow* window, std::vector<sf::Sprite> sprites) 
{ 
    this->TestObject->Render(*window, sprites); 

    window->draw(*this->Player); 
} 

void main_game::Destroy(sf::RenderWindow* window) 
{ 
    delete this->Player; 
    delete this->TestObject; 
} 

這是testObject.h類

#pragma once 

#include "entity.h" 

class testObject : public Entity 
{ 
public: 
    testObject(); 
    void Initialize(); 
    void Render(sf::RenderWindow window, std::vector<sf::Sprite> sprites); 
    void Update(); 
private: 
    sf::RenderWindow window; 
}; 

這是testObject.cpp類

#include "testObject.h" 

testObject::testObject() 
{ 
    this->Load("testObject.png"); 
} 

void testObject::Initialize() 
{ 
    sf::Texture testObjectTexture; 
    sf::Sprite testObjectSprite; 

    testObjectTexture.loadFromFile("testObject.png"); 
    testObjectSprite.setTexture(testObjectTexture); 

    std::vector<sf::Sprite> sprites(5, sf::Sprite(testObjectSprite)); 

    srand(time(0)); 

    for (unsigned int i = 0; i < sprites.size(); i++) 
    { 
     sprites[i].setPosition(1 + (rand() % 1024 - 32), rand() % 640 - 32); 
    } 
} 

void testObject::Render(sf::RenderWindow window, std::vector<sf::Sprite> sprites) 
{ 
    for (unsigned int i = 0; i < sprites.size(); i++) 
    { 
     window.draw(sprites[i]); 
    } 
} 

void testObject::Update() 
{ 
    Entity::Update(); 
} 

該錯誤消息

Answer 1

此特定錯誤，（雖然我敢肯定，你將有更多的，一旦你解決這個問題），可能來源於此：

void testObject::Render(sf::RenderWindow window, std::vector<sf::Sprite> sprites) 

您傳遞RenderWindow的價值，但它是非可複製。改爲通過引用或指針傳遞它。

好的，我解決了這個問題，但現在它不會給我任何錯誤，所以這很好，但它不會渲染任何東西。
