main.h结构体Glo中加入选项Tank *player.

class QImage;
class GameMap;
class Tank;
typedef struct{
unsigned int framei;
QImage *blockimage;
GameMap *gamemap;
Tank *player;
}Glo;//实列化Glo类型变量，能实列化出来,所有的指针变量所占空间daxiao一样。

mainwindow.cpp paintEvent函数变更如下

void MainWindow::paintEvent(QPaintEvent *event)
{
Q_UNUSED(event);

setFixedSize(WIDTH,HEIGHT);

paint.begin(this);
glo.gamemap->Display(paint);
