memory小游戏
之前在Coursera上学习python课程的时候写的一个memory的小游戏。属于记忆类的小游戏。
原来的memory是所有的纸牌都排成一列的，通过点击来翻牌，如果最近的两次翻的牌都一样那么就成功了，牌会保持翻开的状态。如下图所示：
实现代码：
# implementation of card game - Memory
# by Sean
import simplegui
import random
# helper function to initialize globals
def init():
global deck, exposed, card_list, moves
deck = [(i // 2) for i in range(0, 16)]
random.shuffle(deck)
exposed = []
for i in range(0, 16):
exposed.append(False)
card_list = []
moves = 0
l.set_text("Moves = 0")
# define event handlers
def mouseclick(pos):
global exposed, state, moves
card_checked = int(pos[0]) * 2 // 100
if exposed[card_checked] == True:
return
moves += 1
l.set_text("Moves = " + str((moves + 1) // 2))
exposed[card_checked] = True
if len(card_list) == 0:
card_list.append(card_checked)
elif len(card_list) == 1:
card_list.append(card_checked)
else:
card1, card2 = card_list.pop(), card_list.pop()
if deck[card1] != deck[card2]:
exposed[card1], exposed[card2] = False, False
card_list.append(card_checked)
# cards are logically 50x100 pixels in size
def draw(canvas):
SIDE_LEN = 50
for i in range(0, 16):
canvas.draw_text(str(deck[i]), [5 + SIDE_LEN * i, 75], 60, "White")
if not exposed[i]:
canvas.draw_polygon(([SIDE_LEN * i, 0], [SIDE_LEN * (i + 1), 0], [SIDE_LEN * (i + 1), 100], [SIDE_LEN * i, 100]), 1, "Red", "Green")
# create frame and add a button and labels
frame = simplegui.create_frame("Memory", 800, 100)
frame.add_button("Restart", init)
l = frame.add_label("Moves = 0")
# initialize global variables
init()
# register event handlers
frame.set_mouseclick_handler(mouseclick)
frame.set_draw_handler(draw)
# get things rolling
frame.start()
现做出如下改动：
将牌面放在一个二维的平面上。
将原来的牌的正面数字以及牌的背面均用图片代替。
使用pygame.

main()
可以看到里面的一些函数还是空的。因为没有太多时间和精力去完善它，尽管是很小的东西，但是要做的精致还是很困难的。
下面是游戏运行的截图：
当所有牌都是正面的时候就gameover了。
体会感悟：
虽然做的东西很简单，但全都是自己一点一点做的，每张图片，每个图片的处理，每行代码都认真的考虑过，修改过，所以完成的时候还是挺开心的。功能方面还是有很多可以添加和改进的，可以很容易想到的就有，对于点击次数的计数，还可以添加关卡设置不同难度，玩家排名数据统计等等，但要全部实现实在精力有限。或许有闲暇时间会来再次改进。（剪图片挺有意思的^-^）
