如何用python写2048
2048游戏规则:简单的移动方向键让数字叠加,并且获得这些数字每次叠加后的得分,当出现2048这个数字时游戏胜利。同时每次移动方向键时,都会在这个4*4的方格矩阵的空白区域随机产生一个数字2或者4,如果方格被数字填满了,那么就GameOver了。
来一步步的进行剖析:
(1)生成4*4的棋盘, 其中数据结构为列表嵌套列表
field = [[0 for j in range(4)] for i in range(4)]
(2)创建函数random_create, 在棋盘的一个随机位置插入一个数字2或者4,其中2的几率大
import random def random_create(): i = random.choice(range(4)) j = random.choice(range(4)) value = random.choice([2,2,2,4]) field[i][j] = value
(3)如果随机插入数字的位置已经有内容, 如何解决覆盖原有数字的问题
def random_creat(): while True: i = random.choice(range(4)) j = random.choice(range(4)) if li[i][j] == 0: li[i][j] = 4 if random.randint(1, 100) > 80 else 2 break random_creat() random_creat()
(4)将生成的数据, 通过图像画出来
def draw_sep(): print('+-----' * 4 + '+') def draw_num(row): print(''.join('|{:^5}'.format(num) if num != 0 else '| ' for num in row) + '|') for row in li: draw_sep() draw_num(row) draw_sep()
(5)矩阵的反转
def invert(field): return [row[::-1] for row in field]
(6)矩阵的转秩
def transpose(field): return [list(row) for row in zip(*field)]
(7)判断棋盘是否可移动
def is_row_change(row): # row # 判断一行内容是否可以移动 def is_change(i): # 判断每两个元素之间是否可以移动 if row[i] == 0 and row[i + 1] != 0: return True if row[i] != 0 and row[i + 1] == row[i]: return True else: return False return any([is_change(index) for index in range(len(row) - 1)])
(8)判断这个棋盘是否可左右上下移动
def is_move_left(field): return any([is_row_change(row) for row in field]) def is_move_right(field): # 对于列表元素进行反转 field = invert(field) print(field) return is_move_left(field) def is_move_up(field): # 对于列表元素进行转置 field = transpose(field) return is_move_left(field) def is_move_down(field): # 反转+ 转置 field = transpose(field) return is_move_right(field)
棋盘的移动,相加
def tight(row): # [2, 0, 2, 0] # 最快的方式, 通过排序实现........... return sorted(row, key=lambda x: if x == 0 ) score = 0 # 相加 def merge(row): # [2,2,0,0] # [0,1,2] for i in range(len(row)-1): # 如果两个值相等, 前一个元素*2, 后一个元素改为0。 if row[i] == row[i+1]: row[i] *= 2 row[i+1] = 0 # 如果覆盖成功, 就给得分 global score score += row[i] return row
棋盘左右上下移动相加
def move_row_left(self, row): return self.tight(self.merge(self.tight(row))) def move_left(self, field): return [self.move_row_left(row) for row in field] def move_right(self, field): field = self.invert(field) return self.invert([self.move_row_left(row) for row in field]) def move_up(self, field): return self.transpose([self.move_row_left(row) for row in self.transpose(field)]) def move_down(self, field): return self.invert(self.transpose([self.move_row_left(row) for row in self.invert(self.transpose(field))]))
(9)判断游戏的胜利与结束
#判断游戏何时胜利:当棋盘中出现2048时,就代表着游戏胜利 def victory(field): li = [y for row in li for y in row] if max(li) >= 2048: print('Victory') def game_over(filed): if all((is_move_left(filed), is_move_right(filed), is_move_up(filed), is_move_down(filed))) == False: print('Game Over')
这样程序的各个部分就写好了,将各个部分封装到一个类里面,再导入curses模块来控制游戏,就可以了。
