Le projet sur lequel je travaille est supposé modéliser une impulsion descendant un ensemble de sphères reliées par des ressorts. J'essaie de diminuer la longueur du ressort lorsque le pouls descend dans la chaîne, mais quand je le lance, rien ne se passe.La boucle pour changer les longueurs de ressort ne change rien quand je l'exécute
Voici mon code:
from visual import *
one = sphere(pos=(-10,0,0), radius = 0.5, color = color.red)
two = sphere(pos=(-8,0,0), radius = 0.5, color = color.orange)
three = sphere(pos=(-6,0,0), radius = 0.5, color = color.yellow)
four = sphere(pos=(-4,0,0), radius = 0.5, color = color.green)
five = sphere(pos=(-2,0,0), radius = 0.5, color = color.blue)
six = sphere(pos=(0,0,0), radius = 0.5, color = color.cyan)
seven = sphere(pos=(2,0,0), radius = 0.5, color = color.magenta)
eight = sphere(pos=(4,0,0), radius = 0.5, color = color.white)
nine = sphere(pos=(6,0,0), radius = 0.5, color = color.red)
ten = sphere(pos=(8,0,0), radius = 0.5, color = color.orange)
spring1 = helix(pos = (-10, 0, 0), length = 2, radius = 0.3,
thickness = 0.05, color = color.red)
spring2 = helix(pos = (-8, 0, 0), length = 2, radius = 0.3,
thickness = 0.05, color = color.orange)
spring3 = helix(pos = (-6, 0, 0), length = 2, radius = 0.3,
thickness = 0.05, color = color.yellow)
spring4 = helix(pos = (-4, 0, 0), length = 2.0, radius = 0.3,
thickness = 0.05, color = color.green)
spring5 = helix(pos = (-2, 0, 0), length = 2.0, radius = 0.3,
thickness = 0.05, color = color.blue)
spring6 = helix(pos = (0, 0, 0), length = 2.0, radius = 0.3,
thickness = 0.05, color = color.cyan)
spring7 = helix(pos = (2, 0, 0), length = 2.0, radius = 0.3,
thickness = 0.05, color = color.magenta)
spring8 = helix(pos = (4, 0, 0), length = 2.0, radius = 0.3,
thickness = 0.05, color = color.white)
spring9 = helix(pos = (6, 0, 0), length = 2.0, radius = 0.3,
thickness = 0.05, color = color.red)
masses = [one, two, three, four, five, six, seven, eight, nine, ten]
springs = [spring1, spring2, spring3, spring4, spring5, spring6, spring7,
spring8, spring9]
while True:
n=0
deltax=.2
while n < 10:
rate(30)
masses[n].pos.x = masses[n].pos.x + deltax
if n < 9:
springs[n].pos = masses[n].pos
springs[n].axis = masses[n+1].pos-masses[n].pos
n=n+1
n = n-1
while n >= 0:
rate(30)
masses[n].pos.x = masses[n].pos.x - deltax
if n < 0:
springs[n-1].pos = masses[n-1].pos - deltax
springs[n-1].axis = masses[n].pos-masses[n-1].pos
n = n-1
while True:
m=0

while m<9:
