1.pygame事件
- QUIT:关闭按钮被点击事件
MOUSEBUTTONDOWN:鼠标按下MOUSEBUTTONUP：鼠标弹起
MOUSEMOTION：鼠标移动
关心鼠标事件产生的位置
pos属性，获取鼠标事件产生的位置
KEYDOWN：键盘按键被按下
KEYUP：键盘按钮弹起
关心键盘事件产生的位置
*key属性，获取被按的按键对应的Unicode编码
*chr,将Unicode转换为字符
import pygame
if __name__ == '__main__':
pygame.init()
screen=pygame.display.set_mode((600,400))
screen.fill((255,255,255))
# screen.blit()
# 设置游戏事件
pygame.display.set_caption('游戏事件')
pygame.display.flip()
while True:
#每次循环检查事件
for event in pygame.event.get():
#不同类型的事件对应的type值不一样
# pos属性，获取鼠标事件产生的位置
if event.type==pygame.QUIT:
exit()
if event.type==pygame.MOUSEBUTTONDOWN:
print('鼠标按下',event.pos)
if event.type==pygame.MOUSEBUTTONUP:
print('鼠标弹起',event.pos)
if event.type==pygame.MOUSEMOTION:
print('鼠标移动',event.pos)
#键盘相关事件
if event.type==pygame.KEYDOWN:
print('键盘按键被按下',chr(event.key))
if event.type==pygame.KEYUP:
print('键盘按钮弹起',chr(event.key))
2.pygame的应用
import pygame
from random import randint
# 画一个按钮
def draw_button(screen,btn_color,title_color):
# 画个鼠标
'''矩形框'''
pygame.draw.rect(screen, btn_color, (100, 100, 100, 60))
'''文字'''
font = pygame.font.SysFont('Times', 30)
title = font.render('clicke', True, title_color)
screen.blit(title, (120, 110))
# 写一个函数，判断指定的点是否在指定的矩形范围中
def is_in_rect(point,rect):
x,y=point
rx,ry,rw,rh=rect
if (rx<=x<=rx+rw) and (ry<=y<=ry+rh):
return True
return False
def draw_ball(screen,pos):
pygame.draw.circle(screen, rand_color(), event.pos, randint(10, 20))
# 只要屏幕上的内容有更新，都需要调用下面的两个方法
pygame.display.update()
# pygame.display.flip()
def rand_color():
return randint(0,255),randint(0,255),randint(0,255)
if __name__ == '__main__':
pygame.init()
screen=pygame.display.set_mode((600,400))
screen.fill((255,255,255))
pygame.display.set_caption('鼠标事件')
draw_button(screen, (0, 255, 0), (255, 0, 0))
pygame.display.flip()
while True:
for event in pygame.event.get():
if event.type==pygame.QUIT:
exit()
if event.type==pygame.MOUSEBUTTONDOWN:
# draw_ball(screen,event.pos)
if is_in_rect(event.pos,(100,100,100,60)):
draw_button(screen, (0, 0,255 ), (255, 0, 0))
pygame.display.update()
print('点中按钮')
if event.type==pygame.MOUSEBUTTONUP:
draw_button(screen, (0, 255, 0), (255, 0, 0))
pygame.display.update()
if event.type==pygame.MOUSEMOTION:
screen.fill((255,255,255))
draw_button(screen, (0, 0, 255), (255, 0, 0))
draw_ball(screen,event.pos)

4.动画效果

'''
动画原理：不断的刷新界面上的内容(一帧一帧的画)
'''
import pygame
from random import randint
def static(address):
font=pygame.font.SysFont('Times',40)
title=font.render('welcome',True,(255,0,0))
screen.blit(title,(50,50))
def animation_title(address):
font = pygame.font.SysFont('Times', 40)
title = font.render('welcome', True, (randint(0,255), randint(0,255), randint(0,255)))
screen.blit(title, (100, 100))
if __name__ == '__main__':
pygame.init()
screen=pygame.display.set_mode((600,400))
screen.fill((255,255,255))
static(screen)
pygame.display.flip()
while True:
for event in pygame.event.get():
if event.type==pygame.QUIT:
exit()
# 不断改变字体的颜色
# 程序执行到这个位置，cpu休息一段时间再执行后面的代码(程序堵塞)
# 单位：毫秒(1000ms=1s)
pygame.time.delay(160)
# 内容清空
screen.fill((255,255,255))
static(screen)
animation_title(screen)
# pygame.time.wait(1000)
# 内容展示
pygame.display.update()
