C++ easyx 五子棋游戏

受不了黑框框，想用easyx做一个界面

#include<iostream>
#include<easyx.h>
using namespace std;

struct state {
    int x;
    int y;
    int player;
};
class chess {
public:
    void buildboard(); //棋盘与棋子绘制
    void mouse_confirm(ExMessage *mess);  //鼠标确认
    int judge(int x, int y);
private:
    int chess[15][15]; //存储棋子状态，初始化为0，-1为黑子，1为白子
    state Gstate; //默认黑子先行
};


void chess::buildboard() 
{
    setlinecolor(WHITE);   //设置线条颜色
    setlinestyle(PS_SOLID, 2);
    //线条间距为40
    for (int i = 1; i < 16; i++) {
        line(30, i * 40, 30 + 40 * 14, 40 * i);
    }

        line(30 + i * 40, 40, 30 + i * 40, 40 * 15);
    }
    //绘制边框与棋盘定点
    setlinestyle(PS_SOLID, 4);
    rectangle(30, 40, 30 + 14 * 40, 40 * 15);
    setfillcolor(WHITE);
    solidcircle(30 + 7 * 40, 40 * 8, 5);  //中间

                return 1;
            }
        }
    }
}

int main() {
    chess wuziqi;
    initgraph(800, 720);
    IMAGE background;
    loadimage(&background, "beijin.jpg");  //加载图片
    putimage(0, 0, &background);   //输出图片
    wuziqi.buildboard();
    while (1) {
        ExMessage mess; //处理消息
        //鼠标消息获取
        if (peekmessage(&mess, EX_MOUSE)) //消息类型
        {
            switch (mess.message) {
            case WM_LBUTTONDOWN:  //左键
                wuziqi.mouse_confirm(&mess);
                break;
            default:
                break;
            }
        }

    }
    system("pause");
    return 0;
}

代码每一个部分都完成了，但是为什么不能下棋，是哪里出了问题

以为是坐标的问题，Gstate.x = (int)((mess->x - 30) / 40);

Gstate.y = (int)((mess->y - 40) / 40);

用了强制类型转换，还是不可以

easyx官网上的例子代码很多，可以捡感兴趣的参考一下。
