этот код рисует основы моего симулятора орбит, но как только он совершил одну орбиту с планетой, он переходит на следующую в списке, как мне сделать так, чтобы он выполнял все разные орбиты на одной и той же орбите?время.
#import the library
import pygame,math
#classes
class planet():
def __init__(self,name,colour,distance,eccentricity,radius,x,y,angle):
self.screen = screen
self.name = name
self.colour = colour
self.distance = distance
self.eccentricity = eccentricity
self.radius = radius
self.x = x
self.y = y
self.angle = angle
def draw(self):
pygame.draw.circle(self.screen,self.colour,(self.x,self.y),self.radius,)
def draw_orbit(screen,colour,x,y,r):
screen.fill(Black)
int(r)
pygame.draw.circle(screen,colour,[x,y],r)
pygame.display.flip
orbit()
также я могу сделать так, чтобы в списке был только один элемент, но он никогда не делал больше одного поворота, поэтому, если я добавляю planet.angle + 360 вместо только 360, он делает первыйодин, но никогда не двигается от него.
def orbit(planet):
while planet.angle <= 360:
a = planet.distance*(1.496*10**8)
e = planet.eccentricity
angle_radians = math.radians(planet.angle)
r = a*(1-(e*math.cos(angle_radians)))
planet.x = int(math.cos(angle_radians)*r/10**6)
planet.y = int(math.sin(angle_radians)*r/10**6)
planet.angle +=1
## print(planet.angle)
## print(planet.x,planet.y)
planet.x +=800
planet.y +=400
screen.fill(Black)
pygame.draw.circle(screen,Red,center,10)
