我试着做回合制游戏。现在我试着做网格。我在屏幕上输出关于网格的信息的文本。但是过了一会儿窗口一直关闭。可能我做错了什么？我的代码在下面。
tile. h//网格块

  1. #pragma once
  3. #include "SFML/Graphics.hpp"
  4. #include "AssetManager.h"
  6. class Tile
  7. {
  8. public:
  9.     Tile();
  11.     Tile(float size, sf::Texture texture);
  13.     void setPosition(sf::Vector2f position);    
  14.     sf::Vector2f getPosition() const;
  16.     void setTexture(std::string& filename);
  18.     
  19.     float getTileSize();
  21.     void setShape(); // set the rectangle shape parametrs
  22.     sf::RectangleShape& getShape();
  24. private:
  26.     float tileSize = 0;
  27.     sf::Vector2f tilePosition;
  28.     sf::Texture tileTexture;
  29.     sf::RectangleShape tileShape;
  30. };

我不知道如何解决这个问题。

我知道问题出在哪。我有：

  1. while (window->pollEvent(event_play)) 
  2. {
  3.     if (event_play.key.code == sf::Keyboard::Escape) { window->close(); } }
  4. }

字符串
当我将这个字符串改为下面的字符串时，一切都很好：

  1. while (window->pollEvent(event_play)) 
  2. {
  3.     if (event_play.type == sf::Event::Closed) { window->close(); }
  4. }
