pygame从无到有教会你制作有趣的大小图效果,不看是你的损失,
好的,马上开始。
文章目录
一、实现基本的功能
(一)先搭个架子
import pygame,sys
pygame.init()
screen = pygame.display.set_mode((500, 500))
pygame.display.set_caption('大小框展示')
fcclock = pygame.time.Clock()
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT or event.type == pygame.K_F1:
pygame.quit()
sys.exit()
fcclock.tick(60)
pygame.display.flip() # 刷新窗口
黑黑的框,不截图了。大家都懂。
(二)直接贴个图
1、代码如下:
import pygame,sys
pygame.init()
screen = pygame.display.set_mode((500, 500))
pygame.display.set_caption('大小框展示')
img = pygame.image.load('./image/aerial-alpine-ceresole-reale-desktop-backgrounds-1562.jpg').convert_alpha()
fcclock = pygame.time.Clock()
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT or event.type == pygame.K_F1:
pygame.quit()
sys.exit()
screen.blit(img,(0,0))
fcclock.tick(60)
pygame.display.flip() # 刷新窗口
2、运行效果
(三)截取部分图
1、简单截取
screen.blit(img,(0,0),(1000,1000,500,500))
2、让部分截图动起来
# aerial-alpine-ceresole-reale-desktop-backgrounds-1562.jpg
import pygame,sys
pygame.init()
screen = pygame.display.set_mode((500, 500))
pygame.display.set_caption('大小框展示')
fcclock = pygame.time.Clock()
img = pygame.image.load('./image/aerial-alpine-ceresole-reale-desktop-backgrounds-1562.jpg').convert_alpha()
i = 0
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT or event.type == pygame.K_F1:
pygame.quit()
sys.exit()
screen.blit(img,(0,0),(i,1000,500,500))
i += 1
fcclock.tick(60)
pygame.display.flip() # 刷新窗口
3、显示个全图出来吧
import pygame,sys
pygame.init()
screen = pygame.display.set_mode((500, 500))
pygame.display.set_caption('大小框展示')
fcclock = pygame.time.Clock()
img = pygame.image.load('./image/aerial-alpine-ceresole-reale-desktop-backgrounds-1562.jpg').convert_alpha()
img = pygame.transform.scale(img, (500, 500))
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT or event.type == pygame.K_F1:
pygame.quit()
sys.exit()
screen.blit(img,(0,0))
fcclock.tick(60)
pygame.display.flip() # 刷新窗口
二、实现右下角半透明化小图
(一)初始化小图surface
img_small = pygame.transform.scale(img_big, (int(img_big.get_rect().width/flag), int(img_big.get_rect().height/flag)))
bgSurface = pygame.Surface((int(img_big.get_rect().width/flag), int(img_big.get_rect().height/flag)))
pygame.Surface.convert_alpha(bgSurface)
(二)循环过程中画小图
bgSurface.blit(img_small,(0,0))
screen.blit(bgSurface,(screen.get_rect().width - bgSurface.get_rect().width,screen.get_rect().height - bgSurface.get_rect().height))
(三)完整代码
import pygame,sys
flag = 20
pygame.init()
screen = pygame.display.set_mode((500, 500))
pygame.display.set_caption('大小框展示')
fcclock = pygame.time.Clock()
img_big = pygame.image.load('./image/aerial-alpine-ceresole-reale-desktop-backgrounds-1562.jpg').convert_alpha()
print(img_big.get_rect().width,img_big.get_rect().height)
img_small = pygame.transform.scale(img_big, (int(img_big.get_rect().width/flag), int(img_big.get_rect().height/flag)))
bgSurface = pygame.Surface((int(img_big.get_rect().width/flag), int(img_big.get_rect().height/flag)))
pygame.Surface.convert_alpha(bgSurface)
i = 0
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT or event.type == pygame.K_F1:
pygame.quit()
sys.exit()
screen.blit(img_big,(0,0),(i,1000,500,500))
bgSurface.set_alpha(220)
i += 1
bgSurface.blit(img_small,(0,0))
screen.blit(bgSurface,(screen.get_rect().width - bgSurface.get_rect().width,screen.get_rect().height - bgSurface.get_rect().height))
fcclock.tick(60)
pygame.display.flip() # 刷新窗口
(四)运行效果
三、增加小图的选择矩形框
(一)核心代码
bgx = screen.get_rect().width - bgSurface.get_rect().width
bgy = screen.get_rect().height - bgSurface.get_rect().height
posx = i / img_big.get_rect().width * bgSurface.get_rect().width+bgx
posy = j / img_big.get_rect().height * bgSurface.get_rect().height+bgy
rect_rect = (int(posx), int(posy), WIDTH / flag, HEIGHT / flag)
print(rect_rect)
pygame.draw.rect(screen,(255,0,0),rect_rect,2)
(二)完整代码
import pygame,sys
flag = 20
pygame.init()
WIDTH = 500
HEIGHT = 500
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption('大小框展示')
fcclock = pygame.time.Clock()
img_big = pygame.image.load('./image/aerial-alpine-ceresole-reale-desktop-backgrounds-1562.jpg')
print(img_big.get_rect().width,img_big.get_rect().height)
img_small = pygame.transform.scale(img_big, (int(img_big.get_rect().width/flag), int(img_big.get_rect().height/flag)))
bgSurface = pygame.Surface((int(img_big.get_rect().width/flag), int(img_big.get_rect().height/flag)))
pygame.Surface.convert_alpha(bgSurface)
i = 0
j = 1000
bgx = screen.get_rect().width - bgSurface.get_rect().width
bgy = screen.get_rect().height - bgSurface.get_rect().height
# posx = i/img_big.get_rect().width*bgSurface.get_rect().width
# posy = j/img_big.get_rect().height*bgSurface.get_rect().height
# rect_rect = (posx,posy,WIDTH/flag,HEIGHT/flag)
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT or event.type == pygame.K_F1:
pygame.quit()
sys.exit()
screen.blit(img_big,(0,0),(i,j,500,500))
bgSurface.set_alpha(230)
bgSurface.blit(img_small,(0,0))
screen.blit(bgSurface,(bgx,bgy))
posx = i / img_big.get_rect().width * bgSurface.get_rect().width+bgx
posy = j / img_big.get_rect().height * bgSurface.get_rect().height+bgy
rect_rect = (int(posx), int(posy), WIDTH / flag, HEIGHT / flag)
print(rect_rect)
pygame.draw.rect(screen,(255,0,0),rect_rect,2)
i += 1
fcclock.tick(60)
pygame.display.flip() # 刷新窗口
(三)运行效果
上面的都是自动运动的,现在需要实现鼠标响应操作。
四、实现鼠标单击响应操作
(一)实现鼠标响应事件
if event.type == pygame.MOUSEBUTTONDOWN:
choose_rect = pygame.Rect(bgx,bgy,int(img_big.get_rect().width/flag), int(img_big.get_rect().height/flag))
pos = x, y = pygame.mouse.get_pos() # 获取鼠标位置,鼠标就是需要打击的目标
if choose_rect.collidepoint(pos):
print('in')
else:
print('not in')
(二)实现矩形框点击响应函数
if event.type == pygame.MOUSEBUTTONDOWN:
choose_rect = pygame.Rect(bgx,bgy,int(img_big.get_rect().width/flag), int(img_big.get_rect().height/flag))
pos = x, y = pygame.mouse.get_pos() # 获取鼠标位置,鼠标就是需要打击的目标
if choose_rect.collidepoint(pos):
select = True
print('in')
if x-12.5>0:
posx = x-12.5
else:
posx = 0
if y-12.5>0:
posy = y-12.5
else:
posy = 0
rect_rect = (int(posx), int(posy), WIDTH / flag, HEIGHT / flag)
i = (posx-bgx)*img_big.get_rect().width/bgSurface.get_rect().width
j = (posy-bgy)*img_big.get_rect().height/bgSurface.get_rect().height
pygame.draw.rect(screen, (255, 0, 0), rect_rect, 2)
else:
print('not in')
(三)实现效果
五、实现鼠标移动监听事件
初始化变量select=False
(一)鼠标按下
if event.type == pygame.MOUSEBUTTONDOWN:
choose_rect = pygame.Rect(bgx,bgy,int(img_big.get_rect().width/flag), int(img_big.get_rect().height/flag))
pos = x, y = pygame.mouse.get_pos() # 获取鼠标位置,鼠标就是需要打击的目标
if choose_rect.collidepoint(pos):
select = True
print('in')
if x-12.5>0:
posx = x-12.5
else:
posx = 0
if y-12.5>0:
posy = y-12.5
else:
posy = 0
rect_rect = (int(posx), int(posy), WIDTH / flag, HEIGHT / flag)
i = (posx-bgx)*img_big.get_rect().width/bgSurface.get_rect().width
j = (posy-bgy)*img_big.get_rect().height/bgSurface.get_rect().height
pygame.draw.rect(screen, (255, 0, 0), rect_rect, 2)
else:
print('not in')
(二)鼠标移动
if event.type == pygame.MOUSEMOTION:
if select:
choose_rect = pygame.Rect(bgx,bgy,int(img_big.get_rect().width/flag), int(img_big.get_rect().height/flag))
pos = x, y = pygame.mouse.get_pos() # 获取鼠标位置,鼠标就是需要打击的目标
if choose_rect.collidepoint(pos):
