Python绘制时钟的示例代码

2022-09-21 11:11我的天才女友 Python

这篇文章主要介绍了如何利用Python和Pygame库绘制一个简单的时钟效果。文中的示例代码讲解详细,对我们学习Python有一定帮助,需要的可以参考一下

导入需要的包设置变量

from datetime import datetime
from pygame.locals import *
import sys, math, pygame
 
 
def print_text(font, x, y, text, color=(255, 255, 255)):
    img_text = font.render(text, True, color)
    screen.blit(img_text, (x, y))
 
 
def wrap_angle(angle):
    return angle % 360
 
 
pygame.init()
screen = pygame.display.set_mode((600, 500))
pygame.display.set_caption("在线时钟")
 
# 设置字体
font1 = pygame.font.SysFont("方正粗黑宋简体", 24)
orange = 220, 180, 0
white = 255, 255, 255
yellow = 255, 255, 0
pink = 255, 100, 100
 
pos_x = 300
pos_y = 250
radius = 250
angle = 360

这里绘制一个600*500的屏幕,设置圆心位置及其半径。根据时间的不同,计算弧度,通过三角函数计算出对应的坐标,从圆心的位置绘制出时针的线条。

写数字

通过循环1到12,将数字写在对应的位置上,-10 和对应的字体微调使其更加对正

for n in range(1, 13):
    angle = math.radians(n * (360 / 12) - 90)
    x = math.cos(angle) * (radius - 20) - 10
    y = math.sin(angle) * (radius - 20) - 10
    print_text(font1, pos_x + x, pos_y + y, str(n))

绘制时针

这里通过时间计算出对应的角度,然后从圆心到指定位置画时针。

hour_angle = wrap_angle(hours * (360/12) - 90) + wrap_angle(minutes * (360/60) - 90) / 60
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)
