一、先把pygame的框架搭起来
import pygame,sys
pygame.init()
screen=pygame.display.set_mode((600,500))
pygame.display.set_caption('pygame和列表元素有趣的碰撞V1.0')
clock=pygame.time.Clock()
while True:
for event in pygame.event.get():
if event.type==pygame.QUIT:
pygame.quit()
sys.exit()
screen.fill((0,0,0))
clock.tick(300)
pygame.display.update()
黑黑的框框，熟悉的味道
二、来个矩形框吧
pygame.draw.rect(screen,(255,0,0),(200,200,300,100),2)
pygame.draw.rect(screen,(255,0,0),(200,200,300,100))
看到区别了吗？
那就来个红色边框加绿色填充的矩形框吧。
import pygame,sys
pygame.init()
screen=pygame.display.set_mode((600,500))
pygame.display.set_caption('pygame和列表元素有趣的碰撞V1.0')
clock=pygame.time.Clock()
while True:
for event in pygame.event.get():
if event.type==pygame.QUIT:
pygame.quit()
sys.exit()
screen.fill((0,0,0))
pygame.draw.rect(screen,(0,255,0),(200,200,300,100))
pygame.draw.rect(screen,(255,0,0),(200,200,300,100),2)
clock.tick(300)
pygame.display.update()
三、来一箩筐的矩形框吧
用list对象存储起来
（一）初始化list对象
rect_list =[((255,0,0),(95,95,300,100),2)]
i = 0
j = 5
while i < 10:
color = (random.randint(0,255),random.randint(0,255),random.randint(0,255))
a_rect = (100+i*j,100+i*j,300,100)
width = random.randint(1,3)
rect_list.append((color,a_rect,width))
i += 1
（二）展示list元素
for myrect in rect_list:
pygame.draw.rect(screen,myrect[0],myrect[1])
pygame.draw.rect(screen,myrect[0],myrect[1],myrect[2])
发现红色的第一个框显示在最下面了，因此我们需要倒序处理以下list对象。
（三）实现list元素倒序显示
for myrect in rect_list[::-1]:
pygame.draw.rect(screen,myrect[0],myrect[1])
pygame.draw.rect(screen,myrect[0],myrect[1],myrect[2])
OK，红色的显示在最前面了。
四、实现鼠标响应事件
（一）实现鼠标事件
for event in pygame.event.get():
if event.type==pygame.QUIT:
pygame.quit()
sys.exit()
if event.type == pygame.MOUSEBUTTONDOWN:
rect_list.pop(0)
（二）完整代码
import pygame,sys
import random
pygame.init()
screen=pygame.display.set_mode((600,500))
pygame.display.set_caption('pygame和列表元素有趣的碰撞V1.0')
rect_list =[((255,0,0),(95,95,300,100),2)]
i = 0
j = 5
while i < 10:
color = (random.randint(0,255),random.randint(0,255),random.randint(0,255))
a_rect = (100+i*j,100+i*j,300,100)
width = random.randint(1,3)
rect_list.append((color,a_rect,width))
i += 1
clock=pygame.time.Clock()
while True:
for event in pygame.event.get():
if event.type==pygame.QUIT:
pygame.quit()
sys.exit()
if event.type == pygame.MOUSEBUTTONDOWN:
rect_list.pop(0)
screen.fill((0,0,0))
for myrect in rect_list[::-1]:
pygame.draw.rect(screen,myrect[0],myrect[1])
pygame.draw.rect(screen,myrect[0],myrect[1],myrect[2])
clock.tick(300)
pygame.display.update()
（三）运行效果
发现list随着鼠标的点击，越来越少元素了，最后没有了。
（四）在删除第一个元素的同时，增加新元素，进行补给
if event.type == pygame.MOUSEBUTTONDOWN:
rect_list.pop(0)
color = (random.randint(0,255),random.randint(0,255),random.randint(0,255))
a_rect = (100+i*j,100+i*j,300,100)
width = random.randint(1,3)
rect_list.append((color,a_rect,width))
（五）增加移去第一个元素的动态事件
while True:
for event in pygame.event.get():
if event.type==pygame.QUIT:
pygame.quit()
sys.exit()
if event.type == pygame.MOUSEBUTTONDOWN:
if cur_rect is None:
cur_rect = rect_list[0]
rect_list.pop(0)
color = (random.randint(0,255),random.randint(0,255),random.randint(0,255))
a_rect = (100+i*j,100+i*j,300,100)
width = random.randint(1,3)
rect_list.append((color,a_rect,width))
flag = random.randint(0,3)
（六）检测是否为空，如果不为空，移动
if cur_rect is not None:
move(screen,flag)
（七）实现move函数
step = 0
def move(screen,i):
global step,cur_rect
if i == 0:
newrect = (cur_rect[1][0] - step,cur_rect[1][1],cur_rect[1][2],cur_rect[1][3])
elif i == 1:
newrect = (cur_rect[1][0] + step,cur_rect[1][1],cur_rect[1][2],cur_rect[1][3])
# cur_rect[1][0] += step
elif i == 2:
newrect = (cur_rect[1][0] ,cur_rect[1][1]+ step,cur_rect[1][2],cur_rect[1][3])
# cur_rect[1][1] += step
elif i == 3:
newrect = (cur_rect[1][0],cur_rect[1][1]- step,cur_rect[1][2],cur_rect[1][3])
# cur_rect[1][1] += step
pygame.draw.rect(screen, cur_rect[0], newrect)
pygame.draw.rect(screen, cur_rect[0], newrect, cur_rect[2])
step += 5
if newrect[0]<0 or newrect[0]>600 or newrect[1] <0 or newrect[1] > 500:
step = 0
cur_rect = None
如果出界，置为None
五、实现效果
