大家好,又見面了,我是你們的朋友全棧
int main(){ Init();//初始化while (!die){ ProcessKey();//處理按鍵Move();//移動蛇Judge();//碰撞檢測Draw();//畫圖Sleep(snack.timeperstep);//延時}while (_getch() != 27);//游戲結束后按esc退出}void Init(){ SetConsoleTitleW(L"貪吃蛇");system("MODE CON: COLS=64 LINES=32");snack.body.push_back(new COORD{ 15,15});snack.body.push_back(new COORD{ 14,15 });GenerateFood();}這里有坑,方向鍵會產生兩個鍵碼,所以要用兩次getch。方向鍵會先產生-32鍵碼,然后產生72 75 77 80這四個鍵碼中的一個
void ProcessKey(){ Direction before = snack.heading;snack.timeperstep = 1000 / snack.body.size();char ch1, ch2;while (_kbhit()){ ch1 = _getch();switch (ch1){ case VK_ESCAPE:if (_getch() == 27)exit(0);break;case -32:switch (ch2 = _getch()){ case 72://upif (Direction::down != before)snack.heading = Direction::up;break;case 80://downif (Direction::up != before)snack.heading = Direction::down;break;case 75://leftif (Direction::right != before)snack.heading = Direction::left;break;case 77://rightif (Direction::left != before)snack.heading = Direction::right;}break;case VK_SPACE:snack.timeperstep = snack.timeperstep = 300 / snack.body.size();;}}}這里只是把頭往前移動了一格
void Move(){ COORD* head = snack.body.front();switch (snack.heading){ case Direction::up:snack.body.push_front(new COORD{ head->X,head->Y - 1 });break;case Direction::down:snack.body.push_front(new COORD{ head->X,head->Y + 1 });break;case Direction::left:snack.body.push_front(new COORD{ head->X - 1,head->Y });break;case Direction::right:snack.body.push_front(new COORD{ head->X + 1,head->Y });break;}}判斷頭有沒有和食物、墻、身體重疊。這里的坑就是判斷身體的時候,一定要掐頭去尾來判斷
void Judge(){ COORD* head = snack.body.front();if (food.X == head->X && food.Y == head->Y)GenerateFood();else if (head->X < 0 || head->Y < 0 || head->X == 30 || head->Y == 30)die = true;else{ delete snack.body.back();snack.body.pop_back();for (list<COORD*>::iterator i = ++snack.body.begin(); i != snack.body.end(); i++){ if ((*i)->X == head->X && (*i)->Y == head->Y)die = true;}}}用緩沖,先把要輸出到屏幕的東西寫道緩沖區,解決屏閃。大致順序是先畫墻,再畫食物,再畫蛇,如果蛇死了就再畫一個lost
