[英]turtle graphics Turtle slows down
I set the turtle to fastest and when I ran the first loop alone it was fine but as I added more it became comparably to when it was just executing first loop alone.我将乌龟设置为最快,当我单独运行第一个循环时它很好,但是随着我添加更多它变得与单独执行第一个循环时相当。 I don't know if this is just because of the complexity of the drawing but it takes a decently long amount of time to complete the shape.我不知道这是否只是因为绘图的复杂性,但完成形状需要相当长的时间。 Is there anthing I can do to fix this?我能做些什么来解决这个问题吗?
import turtle
turtle.bgcolor("Red")
turtle.color("Yellow", "Pink")
turtle.shape("turtle")
turtle.begin_fill()
turtle.speed("fastest")
while True:
turtle.forward(300)
turtle.left(179)
turtle.circle(20)
if abs(turtle.pos()) < 1:
break
turtle.setheading(270)
while True:
turtle.forward(300)
turtle.left(179)
turtle.circle(20)
if abs(turtle.pos()) < 1:
break
turtle.setheading(180)
while True:
turtle.forward(300)
turtle.left(179)
turtle.circle(20)
if abs(turtle.pos()) < 1:
break
turtle.setheading(90)
while True:
turtle.forward(300)
turtle.left(179)
turtle.circle(20)
if abs(turtle.pos()) < 1:
break
turtle.end_fill()
turtle.getscreen()._root.mainloop()
My analysis is that your filling, ie turtle.begin_fill()
and turtle.end_fill()
, is slowing down the code 3X to no real effect.我的分析是您的填充,即turtle.begin_fill()
和turtle.end_fill()
将代码减慢了3 倍,但没有实际效果。 One of these images is with fill, one is without :这些图像之一是填充,一个是没有:
If you can't appreciate the difference (even at full size) then the fill is probably just a waste of time.如果您无法体会差异(即使是全尺寸),那么填充可能只是浪费时间。 If you just want the final image, and don't care about watching it being drawn, then for more performance, I suggest something like:如果您只想要最终图像,而不关心观看它的绘制,那么为了获得更高的性能,我建议如下:
from turtle import Screen, Turtle
screen = Screen()
screen.bgcolor("Red")
screen.tracer(False)
turtle = Turtle(visible=False)
turtle.color("Yellow", "Pink")
for heading in range(0, 360, 90):
turtle.setheading(heading)
turtle.begin_fill()
while True:
turtle.forward(300)
turtle.left(179)
turtle.circle(20)
if abs(turtle.pos()) < 1:
break
turtle.end_fill()
screen.tracer(True)
screen.mainloop()
