150行Python代码模拟太阳系行星运转

今天我们用Python来模拟一下太阳系行星运动轨迹玩玩~

先上成品图（运行效果含音乐的呦）

想要实现这样的效果并不难

1、准备材料

首先我们需要准备这样一些材料

宇宙背景图

背景透明的行星图

2：编写代码

代码分块详解

导入需要的模块

import pygame
import sys
import math
from pygame.locals import *

定义窗口大小、标题名称、字体设置、创建时钟

size = width, height = 1206, 780
screen = pygame.display.set_mode(size)
pygame.display.set_caption("太阳系行星运转示意图")
myfont = pygame.font.Font(None,60)
clock = pygame.time.Clock()

宇宙背景初始化

background = pygame.image.load(r" 这里填背景图片本地路径 ")screen.blit(background, (0, 0))

右侧文字及星球显示

    textImage = myfont.render("Solar System", True, (255, 255, 0))           # 太阳系screen.blit(textImage, (100, 100))my_font = pygame.font.SysFont("arial", 15)text_surface = my_font.render("Sun", True, (255, 0, 0), (0, 0, 0))       # 太阳screen.blit(text_surface, (1020, 30))sun = pygame.image.load(r"F:\solar-system\image\sun_bg.png")screen.blit(pygame.transform.scale(sun, (27, 27)), (1090, 25))my_font = pygame.font.SysFont("arial", 15)text_surface = my_font.render("Mercury", True, (255, 0, 0), (0, 0, 0))   # 水星screen.blit(text_surface, (1020, 70))my_font = pygame.font.SysFont("arial", 15)Mercury = pygame.image.load(r"F:\solar-system\image\mercury_bg.png")screen.blit(pygame.transform.scale(Mercury, (27, 27)), (1090, 65))text_surface = my_font.render("Venus", True, (255, 0, 0), (0, 0, 0))     # 金星screen.blit(text_surface, (1020, 110))my_font = pygame.font.SysFont("arial", 15)spark = pygame.image.load(r"F:\solar-system\image\spark_bg.png")screen.blit(pygame.transform.scale(spark, (27, 27)), (1090, 105))text_surface = my_font.render("Earth", True, (255, 0, 0), (0, 0, 0))     # 地球screen.blit(text_surface, (1020, 150))my_font = pygame.font.SysFont("arial", 15)earth = pygame.image.load(r"F:\solar-system\image\earth_min_bg.png")screen.blit(pygame.transform.scale(earth, (27, 27)), (1090, 145))text_surface = my_font.render("Moon", True, (255, 0, 0), (0, 0, 0))      # 月球screen.blit(text_surface, (1020, 190))my_font = pygame.font.SysFont("arial", 15)moon = pygame.image.load(r"F:\solar-system\image\mercury_bg.png")screen.blit(pygame.transform.scale(moon, (27, 27)), (1090, 185))text_surface = my_font.render("Mars", True, (255, 0, 0), (0, 0, 0))      # 火星screen.blit(text_surface, (1020, 230))Mars = pygame.image.load(r"F:\solar-system\image\venus_bg.png")screen.blit(pygame.transform.scale(Mars, (27, 27)), (1090, 225))my_font = pygame.font.SysFont("arial", 15)text_surface = my_font.render("Jupiter", True, (255, 0, 0), (0, 0, 0))   # 木星screen.blit(text_surface, (1020, 270))Jupiter = pygame.image.load(r"F:\solar-system\image\jupiter_min_bg.png")screen.blit(pygame.transform.scale(Jupiter, (27, 27)), (1090, 265))my_font = pygame.font.SysFont("arial", 15)text_surface = my_font.render("Saturn", True, (255, 0, 0), (0, 0, 0))    # 土星screen.blit(text_surface, (1020, 300))Saturn = pygame.image.load(r"F:\solar-system\image\saturn_bg.png")screen.blit(pygame.transform.scale(Saturn, (30, 30)), (1090, 305))my_font = pygame.font.SysFont("arial", 15)text_surface = my_font.render("Uranus", True, (255, 0, 0), (0, 0, 0))    # 天王星screen.blit(text_surface, (1020, 340))Uranus = pygame.image.load(r"F:\solar-system\image\uranus_bg.png")screen.blit(pygame.transform.scale(Uranus, (27, 27)), (1090, 345))my_font = pygame.font.SysFont("arial", 15)text_surface = my_font.render("Neptune", True, (255, 0, 0), (0, 0, 0))   # 海王星screen.blit(text_surface, (1020, 380))Neptune = pygame.image.load(r"F:\solar-system\image\neptune_bg.png")screen.blit(pygame.transform.scale(Neptune, (27, 27)), (1090, 385))

设定太阳初始位置

sun = pygame.image.load(r"F:/solar-system/image/sun_bg.png")
screen.blit(pygame.transform.scale(sun, (170, 170)), (527,307))

实现各个星球绕着太阳转

    # 水星roll_3 += 0.077  # 每帧公转pipos_3_x = int(size[0] // 2 + size[1] // 8 * math.sin(roll_3))pos_3_y = int(size[1] // 2 + size[1] // 8 * math.cos(roll_3))mercury = pygame.image.load(r"F:\solar-system\image\mercury_bg.png")screen.blit(pygame.transform.scale(mercury, (8, 8)), (pos_3_x, pos_3_y))# 金星roll_2 += 0.069  # 每帧公转pipos_2_x = int(size[0] // 2 + size[1] // 7 * math.sin(roll_2))pos_2_y = int(size[1] // 2 + size[1] // 7 * math.cos(roll_2))venus = pygame.image.load(r"F:\solar-system\image\venus_bg.png")screen.blit(pygame.transform.scale(venus, (10, 10)), (pos_2_x, pos_2_y))# 地球roll_e += 0.060  # 每帧公转pipos_e_x = int(size[0] // 2 + size[1] // 6 * math.sin(roll_e))pos_e_y = int(size[1] // 2 + size[1] // 6 * math.cos(roll_e))earth = pygame.image.load(r"F:\solar-system\image\earth_min_bg.png")screen.blit(pygame.transform.scale(earth, (15, 15)), (pos_e_x, pos_e_y))# 火星roll_4 += 0.053  # 每帧公转pipos_4_x = int(size[0] // 2 + size[1] // 5 * math.sin(roll_4))pos_4_y = int(size[1] // 2 + size[1] // 5 * math.cos(roll_4))venus = pygame.image.load(r"F:\solar-system\image\venus_bg.png")screen.blit(pygame.transform.scale(venus, (13, 13)), (pos_4_x, pos_4_y))# 木星roll_5 += 0.045  # 每帧公转pipos_5_x = int(size[0] // 2 + size[1] // 4 * math.sin(roll_5))pos_5_y = int(size[1] // 2 + size[1] // 4 * math.cos(roll_5))mouth = pygame.image.load(r"F:\solar-system\image\jupiter_bg.png")screen.blit(pygame.transform.scale(mouth, (70, 70)), (pos_5_x, pos_5_y))# 土星roll_6 += 0.037  # 每帧公转pipos_6_x = int(size[0] // 2 + size[1] // 3.5 * math.sin(roll_6))pos_6_y = int(size[1] // 2 + size[1] // 3.5 * math.cos(roll_6))saturn = pygame.image.load(r"F:\solar-system\image\saturn_bg.png")screen.blit(pygame.transform.scale(saturn, (50, 50)), (pos_6_x, pos_6_y))# 天王星roll_7 += 0.031  # 每帧公转pipos_7_x = int(size[0] // 2 + size[1] // 2.7 * math.sin(roll_7))pos_7_y = int(size[1] // 2 + size[1] // 2.7 * math.cos(roll_7))uranus = pygame.image.load(r"F:\solar-system\image\uranus_bg.png")screen.blit(pygame.transform.scale(uranus, (45, 45)), (pos_7_x, pos_7_y))# 海王星roll_8 += 0.025  # 每帧公转pipos_8_x = int(size[0] // 2 + size[1] // 2 * math.sin(roll_8))pos_8_y = int(size[1] // 2 + size[1] // 2 * math.cos(roll_8))neptune = pygame.image.load(r"F:\solar-system\image\neptune_bg.png")screen.blit(pygame.transform.scale(neptune, (37, 37)), (pos_8_x, pos_8_y))

实现月亮绕着地球转

roll_m += 0.2  # 每帧公转pi
pos_m_x = int(pos_e_x + size[1] // 50 * math.sin(roll_m))
pos_m_y = int(pos_e_y + size[1] // 50 * math.cos(roll_m))
mouth = pygame.image.load(r"F:\solar-system\image\mercury_bg.png")
screen.blit(pygame.transform.scale(mouth, (6, 6)), (pos_m_x, pos_m_y))

如果你很有情调的话，还可以在循环体之前加一段代码，配曲music

注：此处音乐力求达到宏伟效果，因此选的是 Victory.mp3

# 添加背景音乐
pygame.mixer.music.load('F:/music.mp3')
pygame.mixer.music.play(-1, 40)
pygame.mixer.music.set_volume(0.5)
