Python学习心情记录 2020/3/31
本帖最后由 wuqramy 于 2020-3-31 18:56 编辑今天我们来用Pygame画图。
首先下载Pygame第三方库：
在cmd中输入以下命令
pip install pygame
然后上代码（今天没有附件哦）：
首先我们画三个不同的正方形：
import pygame
import sys
from pygame.locals import *
pygame.init()
WHITE = (255,255,255)
BLACK = (0,0,0)
size = whidth,height = 640,150
screen = pygame.display.set_mode(size)
pygame.display.set_caption('drawing')
clock = pygame.time.Clock()
while True:
for event in pygame.event.get():
if event.type == QUIT:
sys.exit()
screen.fill(WHITE)
pygame.draw.rect(screen,BLACK,(50,50,150,50),0)
pygame.draw.rect(screen,BLACK,(250,50,150,50),1)
pygame.draw.rect(screen,BLACK,(450,50,150,50),10)
pygame.display.flip()
clock.tick(10)
效果如下：
然后是一条鱼：
import pygame
import sys
from pygame.locals import *
pygame.init()
WHITE = (255,255,255)
BLACK = (0,0,0)
GREEN = (0,255,0)
points = [(200,75),(300,25),(400,75),(450,25),(450,125),(400,75),(300,125)]
size = whidth,height = 640,200
screen = pygame.display.set_mode(size)
pygame.display.set_caption('drawing')
clock = pygame.time.Clock()
while True:
for event in pygame.event.get():
if event.type == QUIT:
sys.exit()
screen.fill(WHITE)
pygame.draw.polygon(screen,GREEN,points,0)
pygame.display.flip()
clock.tick(10)
效果如下：
接着：
import pygame
import sys
from pygame.locals import *
pygame.init()
WHITE = (255,255,255)
BLACK = (0,0,0)
GREEN = (0,255,0)
RED = (255,0,0)
BLUE = (0,0,255)
size = whidth,height = 620,480
screen = pygame.display.set_mode(size)
pygame.display.set_caption('drawing')
position = size // 2,size // 2
moving = False
clock = pygame.time.Clock()
while True:
for event in pygame.event.get():
if event.type == QUIT:
sys.exit()
if event.type == MOUSEBUTTONDOWN:
if event.button == 1:
moving = True
if event.type == MOUSEBUTTONUP:
if event.button == 1:
moving = False
if moving:
position = pygame.mouse.get_pos()
screen.fill(WHITE)
pygame.draw.circle(screen,RED,position,25,1)
pygame.draw.circle(screen,GREEN,position,75,1)
pygame.draw.circle(screen,BLUE,position,125,1)
pygame.display.flip()
clock.tick(120)
画出了个靶子：
嘿！这个靶子还能移动！：
这里还剩下了两段代码，大家可以把运行结果留言在评论区：
代码1：
import pygame
import sys
from pygame.locals import *
pygame.init()
WHITE = (255,255,255)
BLACK = (0,0,0)
GREEN = (0,255,0)
RED = (255,0,0)
BLUE = (0,0,255)
size = whidth,height = 620,300
screen = pygame.display.set_mode(size)
pygame.display.set_caption('drawing')
position = size // 2,size // 2
clock = pygame.time.Clock()
while True:
for event in pygame.event.get():
if event.type == QUIT:
sys.exit()
screen.fill(WHITE)
pygame.draw.ellipse(screen,BLACK,(100,100,440,100),1)
pygame.draw.ellipse(screen,BLACK,(220,50,200,200),1)
pygame.display.flip()
clock.tick(120)
代码2：
import pygame
import sys
from pygame.locals import *
pygame.init()
WHITE = (255,255,255)
BLACK = (0,0,0)
GREEN = (0,255,0)
points = [(200,75),(300,25),(400,75),(450,25),(450,125),(400,75),(300,125)]
size = whidth,height = 640,480
screen = pygame.display.set_mode(size)
pygame.display.set_caption('drawing')
clock = pygame.time.Clock()
while True:
for event in pygame.event.get():
if event.type == QUIT:
sys.exit()
screen.fill(WHITE)
pygame.draw.lines(screen,GREEN,1,points,1)
pygame.draw.line(screen,BLACK,(100,200),(540,250),1)
pygame.draw.aaline(screen,BLACK,(100,250),(540,300),1)
pygame.draw.aaline(screen,BLACK,(100,300),(540,350),0)
pygame.display.flip()
clock.tick(10)
嗯，今天就到这里了哦！ 哇哇，大神！
帅气！ Hello. 发表于 2020-3-31 19:04
帅气！
呵呵 呃？@DavidCT 你没看到？ 用turtle他不香吗 乘号 发表于 2020-4-3 08:43
