Python学习心情记录 2020/3/26
本帖最后由 wuqramy 于 2020-3-26 13:27 编辑@DavidCT ，快来，pygame第三期！
首先下载pygame第三方库，在cmd中输入以下命令：
pip install pygame
其次上附件：
注！：请把图片文件放在一个文件夹里，然后在图片名前面加上文件夹路径！
资源打包：
最后上代码：
这是一个裁剪龟兄的程序，玩法：
1.拖戈鼠标，选中一块区域；
2.移动鼠标；
3.再次点击鼠标；
好玩吗？代码如下：
import pygame
import pygame.transform
import sys
from pygame.locals import *
pygame.init()
size = width,height = 400,350
bg = (255,255,255)
clock = pygame.time.Clock()
screen = pygame.display.set_mode(size)
pygame.display.set_caption('cutting turtle')
turtle = pygame.image.load('turtle.png')
select = 0
select_rect = pygame.Rect(0,0,0,0)
drag = 0
position = turtle.get_rect()
position.center = width // 2,height // 2
while True:
for event in pygame.event.get():
if event.type == QUIT:
sys.exit()
elif event.type == MOUSEBUTTONDOWN:
if event.button == 1:
if select == 0 and drag == 0:
pos_start = event.pos
select = 1
elif select == 2 and drag == 0:
capture = screen.subsurface(select_rect).copy()
cap_rect = capture.get_rect()
drag = 1
elif select == 2 and drag == 2:
select = 0
drag = 0
elif event.type == MOUSEBUTTONUP:
if event.button == 1:
if select == 1 and drag == 0:
pos_stop = event.pos
select = 2
if select == 2 and drag == 1:
drag = 2
# 设置背景
screen.fill(bg)
# 更新图片
screen.blit(turtle,position)
if select:
mouse_pos = pygame.mouse.get_pos()
if select == 1:
pos_stop = mouse_pos
select_rect.left,select_rect.top = pos_start
select_rect.width,select_rect.height = pos_stop - pos_start,pos_stop - pos_start
pygame.draw.rect(screen,(0,0,0),select_rect,1)
if drag:
if drag == 1:
cap_rect.center = mouse_pos
screen.blit(capture,cap_rect)
# 更新背景
pygame.display.flip()
# 延时10毫秒
#pygame.time.delay(10)
# 设置帧数
clock.tick(30)
然后还有一个隐身龟兄：
import pygame
import pygame.transform
import sys
pygame.init()
size = width,height = 350,300
bg = (0,0,0)
clock = pygame.time.Clock()
screen = pygame.display.set_mode(size)
pygame.display.set_caption('running turtle')
turtle = pygame.image.load('C:\\Pythonstudy\\mytest\\Pygamestudy\\images\\turtle.png')
background = pygame.image.load('C:\\Pythonstudy\\mytest\\Pygamestudy\\images\\grass.jpg')
position = turtle.get_rect()
position.center = width // 2,height // 2
def blit_alpha(target,source,location,opacity):
x = location
y = location
temp = pygame.Surface((source.get_width(),source.get_height())).convert()
temp.blit(target,(-x,-y))
temp.blit(source,(0,0))
temp.set_alpha(opacity)
target.blit(temp,location)
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
screen.blit(background,(0,0))
blit_alpha(screen,turtle,position,200)
pygame.display.flip()
clock.tick(30)
今天就到这里。

来抢沙发了
你已经是一个成熟的鱼油了，
应该学会不自觉地抢沙发了{:10_256:}

早起打卡了，好吗
试试代码呀！ 隐身的乌龟是渐显吗？

不是，目前还没有做出这种效果啦
