让乌龟从墙上反弹 [英] Getting Turtle to Bounce Off the Walls
问题描述
我正在为某人制作节目,所以他们可以锻炼他们的眼睛,我正在使用乌龟,所以它会随机移动。
我希望乌龟从墙上弹开,这样它就不会从侧面消失,永远不会再被看见!
我看过: TurtleGraphics Python:Bouncing turtle离开墙壁?并使用了jnylen的一些代码,所以有些功劳归于他!
无论如何,这是我的旧的,可怕的代码(这是为了参考):
I am making a program for somebody, so they can exercise their eyes, and I am using the turtle, so it will move randomly. I want the turtle to bounce off the walls, so that it does not disappear off the sides, never to be seen again! I have looked at: TurtleGraphics Python: Bouncing turtle off the walls? and used some code from jnylen, so some credit goes to him! Anyway, here is my old, and terrible code (This is kept for reference):
from random import *
from turtle import *
penup() # Get rid of those lines it leaves behind!
def main():
while True: # I want this to be infinite
a = randint(1,600)
print a
b = randint(1,359)
print b
c = randint(1,600)
print c
d = randint(1,359)
print d #Checking my randoms
forward(a)
edge() # Keep calling edge, so it will bounce on the edge.
left(b)
edge() # Keep calling edge, so it will bounce on the edge.
forward(c)
edge() # Keep calling edge, so it will bounce on the edge.
right(d)
edge() # Keep calling edge, so it will bounce on the edge.
def edge():
x, y = position()
top = window_height()/2
bottom = -top
right = window_width()/2
left = -right
if (x <= left and 90 <= heading() <= 270) or (right <= x and not 90 <= heading() <= 270):
f = 178 * h
left(f)
main()
elif (y <= bottom and heading() >= 180) or (top <= y and heading <= 180):
f = -2 * heading()
left(f)
main()
else:
main()
main()
然而,当我运行它时,我得到了输出:
However, When I run it, I get the output:

left(f)
TypeError: 'int' object is not callable
拜托,有人可以帮我解决这个问题。我已经尝试将 f
设置为 float
,字符串
和 int
,但没有任何作用!这可能是非常明显的事情,所以如果是,抱歉。
Please, can somebody help me fix this. I have tried setting f
to a float
, a string
and an int
, but nothing works! This is probably something really obvious, so if it is, sorry.
这是我新的,希望正确的代码:
Here is my new, and hopefully, correct code:
from random import *
from turtle import *
penup() # Get rid of those lines it leaves behind!
def main():
while True: # I want this to be infinite
a = randint(1,600)
print a
b = randint(1,359)
print b
c = randint(1,600)
print c
d = randint(1,359)
print d #Checking my randoms
forward(a)
x, y = position()
top = window_height()/2
bottom = -top
right = window_width()/2
l = -right
if (x <= l and 90 <= heading() <= 270) or (right <= x and not 90 <= heading() <= 270):
f = 178 * heading()
left(f)
print "1"
elif (y <= bottom and heading() >= 180) or (top <= y and heading <= 180):
f = -2 * heading()
left(f)
print "2"
else:
print "3"
left(b)
x, y = position()
top = window_height()/2
bottom = -top
right = window_width()/2
l = -right
if (x <= l and 90 <= heading() <= 270) or (right <= x and not 90 <= heading() <= 270):
f = 178 * heading()
left(f)
print "1"
elif (y <= bottom and heading() >= 180) or (top <= y and heading <= 180):
f = -2 * heading()
left(f)
print "2"
else:
print "3"
forward(c)
x, y = position()
top = window_height()/2
bottom = -top
right = window_width()/2
l = -right
if (x <= l and 90 <= heading() <= 270) or (right <= x and not 90 <= heading() <= 270):
f = 178 * heading()
left(f)
print "1"
elif (y <= bottom and heading() >= 180) or (top <= y and heading <= 180):
f = -2 * heading()
left(f)
print "2"
else:
print "3"
right(d)
x, y = position()
top = window_height()/2
bottom = -top
right = window_width()/2
l = -right
if (x <= l and 90 <= heading() <= 270) or (right <= x and not 90 <= heading() <= 270):
f = 178 * heading()
left(f)
print "1"
elif (y <= bottom and heading() >= 180) or (top <= y and heading <= 180):
f = -2 * heading()
left(f)
print "2"
else:
print "3"
main()
推荐答案
你覆盖左
命令到这里的int值:
You overwritten the left
command to the int value here:
left = -right
所以当你试图转动你的乌龟
so when you try to turn your turtle with
left(f)
您尝试调用 int
对象,只需重命名本地变量 left
you try to call the int
object, simply rename your local variable left
