试图替换＆＃34;创建玩家＆＃34;这里有void game :: createPlayer，它位于此文件的底部。
#include "Engine.h"
Game::Game()
{
DASH = 0, x = 0, y = 0;
total_enemies = 1;
p_timer = 0;
e_timer = 0;
}
Game::~Game()

void Game::run()

srand((unsigned int)time(NULL));
这是我在实施方面遇到的问题。我试图让它工作，所以我可以使用这个功能来取代＆＃34;创建播放器＆＃34;在void game :: run（）下使用它来创建一个类，但是我无法弄清楚导致它超出范围的原因。任何关于如何实施这一点的帮助将非常感激。

您的player_texture是本地变量。当它在方法结束时超出范围时，它将被销毁。现在你的player_sprite有一个破坏的纹理。由于不知道曾经保存在该纹理中的是什么，SFMl会将其绘制为白色。
您需要做的是确保您的player_texture变量至少与您的播放器变量一样长。
你可以把它放在你的游戏课上。但是你的球员似乎生活在那个级别之外。你会很快发现所有的精灵，你需要一个班级来容纳所有精灵。类似于TextureManager或ResourceHolder的东西。然后你会发现，在一个地方，例如在TextureManager.load（）方法中访问所有外部资源（文件）会更实际。然后你需要你的第一个加载屏幕。欢迎来到游戏世界。
