用指向基类对象的指针输出数据

public int getGameAction(int key)
 {
  if(key == -1||key == KEY_NUM2)
   return UP;
  else if(key == -3||key == KEY_NUM4)
   return LEFT;
  else if(key == -5||key == KEY_NUM5)
   return FIRE;
  else if(key == -4||key == KEY_NUM6)
   return RIGHT;
  else if(key == -2||key == KEY_NUM8)
   return DOWN;
  else
   return 0;
 }

把这段代码放在游戏代码中,即可解决K700左右软键无响应bug.
