我在改变游戏中玩家之间的回合时遇到问题。当我运行它时,它似乎以任何顺序运行。因此,显示轮到谁的文本变得混乱。

            #include <iostream>
            #include "SDLSetup.h"
            using namespace std;

            int p = 1;

            void Player1()
            {
                Player = TTF_RenderText_Solid(font, "Player 1", textColor);
                apply_surface(0, 630, Player, screen);
                SDL_Flip(screen);
                p = 2;
            }

            void Player2()
            {
                Player = TTF_RenderText_Solid(font, "Player 2", textColor);
                apply_surface(0, 630, Player, screen);
                SDL_Flip(screen);
                p = 1;
            }

clean_up();

最佳答案

邪恶的goto turn;引起了问题。切换播放器的代码可能不会执行。
在C ++教科书中,查找关键字continuebreak,因为它们适用于您的do-while循环。

例如,您可以替换

goto turn;




continue;


一些建议:


首先确定板方,无需其他代码。
可能是每个板位的switch语句(例如0 .. 8)。


简化和适当的缩进将向您显示在切换播放器时功能底部为什么存在问题。

使用调试器可以轻松解决此问题。
