我正在尝试为matplotlib(python)中的两个不同的粒子设置动画.我只是想出了一种在matplotlib中对一个粒子进行动画处理的方法,但是我在尝试使程序与多个粒子一起使用时遇到困难.有谁知道哪里出了问题以及如何解决？
import numpy as np
from matplotlib import pyplot as plt
from matplotlib import animation
fig = plt.figure()
fig.set_dpi(100)
fig.set_size_inches(5, 4.5)
ax = plt.axes(xlim=(0, 100), ylim=(0, 100))
enemy = plt.Circle((10, -10), 0.75, fc='r')
agent = plt.Circle((10, -10), 0.75, fc='b')
def init():
#enemy.center = (5, 5)
#agent.center = (5, 5)
ax.add_patch(agent)
ax.add_patch(enemy)
return []
def animationManage(i,agent,enemy):
patches = []
enemy.center = (5, 5)
agent.center = (5, 5)
enemy_patches = animateCos(i,agent)
agent_patches = animateLine(i,enemy)
patches[enemy_patches, agent_patches]
#patches.append(ax.add_patch(enemy_patches))
#patches.append(ax.add_patch(agent_patches))
return enemy_patches
def animateCirc(i, patch):
# It seems that i represents time step
x, y = patch.center
# 1st constant = position and 2nd constant = trajectory
x = 50 + 30 * np.sin(np.radians(i))
y = 50 + 30 * np.cos(np.radians(i))
patch.center = (x, y)
return patch,
def animateLine(i, patch):
x, y = patch.center
x = x + 1
y = x+ 1
patch.center = (x, y)
return patch,
def animateCos(i, patch):
x, y = patch.center
x = x + 0.2
y = 50 + 30 * np.cos(np.radians(i))
patch.center = (x, y)
return patch,
def animateSin(i, patch):
x, y = patch.center
x = x + 0.2
y = 50 + 30 * np.sin(np.radians(i))
patch.center = (x, y)
return patch,
anim = animation.FuncAnimation(fig, animationManage,
init_func=init,
frames=360,
fargs=(agent,enemy,),
interval=20,
blit=True)
plt.show()
动画一个粒子的工作代码

def init():

def animateCirc(i, patch):

# 1st constant = position and 2nd constant = trajectory
x = 50 + 30 * np.sin(np.radians(i))
y = 50 + 30 * np.cos(np.radians(i))
patch.center = (x, y)
return patch,
def animateLine(i, patch):
x, y = patch.center
x = x + 1
y = x+ 1
patch.center = (x, y)
return patch,
def animateCos(i, patch):

x = x + 0.2
y = 50 + 30 * np.cos(np.radians(i))

return patch,
def animateSin(i, patch):
x, y = patch.center
x = x + 0.2

return patch,
anim = animation.FuncAnimation(fig, animateCos,
init_func=init,

plt.show()
解决方法:
import numpy as np
from matplotlib import pyplot as plt
from matplotlib import animation
fig = plt.figure()
fig.set_dpi(100)
fig.set_size_inches(5, 4.5)
ax = plt.axes(xlim=(0, 100), ylim=(0, 100))
enemy = plt.Circle((10, -10), 0.75, fc='r')
agent = plt.Circle((10, -10), 0.75, fc='b')
def init():
enemy.center = (5, 5)
agent.center = (5, 5)
ax.add_patch(agent)
ax.add_patch(enemy)
return []
def animationManage(i,agent,enemy):
animateCos(i,enemy)
animateLine(i,agent)
return []
def animateLine(i, patch):
x, y = patch.center
x += 0.25
y += 0.25
patch.center = (x, y)
return patch,
def animateCos(i, patch):
x, y = patch.center
x += 0.2
y = 50 + 30 * np.cos(np.radians(i))
patch.center = (x, y)
return patch,
anim = animation.FuncAnimation(fig, animationManage,
init_func=init,
frames=360,
fargs=(agent,enemy,),
interval=20,
blit=True,
repeat=True)
plt.show()
