Python使用Pygame实现时钟效果

本文实例为大家分享了Python使用Pygame实现时钟效果的具体代码，供大家参考，具体内容如下

import pygame,sys,math,randomfrom pygame.locals import *from datetime import datetime,date,timedef print_text(font,x,y,text,color=(255,255,255)): imgText=font.render(text,True,color) screen.blit(imgText,(x,y))def wrap_angle(angle): return angle%360#main program beginspygame.init()screen=pygame.display.set_mode((600,500))pygame.display.set_caption('Analog Clock Demo')font=pygame.font.Font(None,36)orange=220,180,0white=255,255,255yellow=255,255,0pink=255,100,100 pos_x=300pos_y=250radius=250angle=360while True: for event in pygame.event.get():if event.type==QUIT: sys.exit() keys=pygame.key.get_pressed() if keys[K_ESCAPE]:sys.exit() screen.fill((0,0,100)) #draw one step around the circle pygame.draw.circle(screen,white,(pos_x,pos_y),radius,6) #draw the block number 1~12 for n in range(1,13):angle=math.radians(n*(360/12)-90)x=math.cos(angle)*(radius-20)-10y=math.sin(angle)*(radius-20)-10print_text(font,x+pos_x,y+pos_y,str(n)) #get the time of day today=datetime.today() hours=today.hour%12 minutes=today.minute seconds=today.second #draw the hours hand hour_angle=wrap_angle(hours*(360/12)-90) hour_angle=math.radians(hour_angle) hour_x=math.cos(hour_angle)*(radius-80) hour_y=math.sin(hour_angle)*(radius-80) target=(pos_x+hour_x,pos_y+hour_y) pygame.draw.line(screen,pink,(pos_x,pos_y),target,25) #draw the minute hand min_angle=wrap_angle(minutes*(360/60)-90) min_angle=math.radians(min_angle) min_x=math.cos(min_angle)*(radius-60) min_y=math.sin(hour_angle)*(radius-60) target=(pos_x+min_x,pos_y+min_y) pygame.draw.line(screen,orange,(pos_x,pos_y),target,12) #draw the second hand sec_angle=wrap_angle(seconds*(360/60)-90) sec_angle=math.radians(sec_angle) sec_x=math.cos(sec_angle)*(radius-40) sec_y=math.sin(sec_angle)*(radius-40) target=(pos_x+sec_x,pos_y+sec_y) pygame.draw.line(screen,yellow,(pos_x,pos_y),target,6) #cover the center pygame.draw.circle(screen,white,(pos_x,pos_y),20) print_text(font,0,0,str(hours)+':'+str(minutes)+':'+str(seconds)) pygame.display.update()

运行结果：
