For a my class, I am tasked with programming a turtle function that is user controlled via the arrow keys. The function displays itself and then a mirror of itself with dots. Each dot should be a completely randomized color. So far, I have this:
from turtle import *
from random import randrange
FRAMES_PER_SECOND = 10
mirrorTurtle = Turtle()
def turnRight():
global turtle
global mirrorTurtle
turtle.right(45)
def turnLeft():
global turtle
global mirrorTurtle
turtle.left(45)
def randomColor(turtle):
r = randrange(256) # red component of color
g = randrange(256) # green component
b = randrange(256) # blue component
def move():
colormode(255)
global turtle
global mirrorTurtle
global moving
if moving:
for i in range(1):
turtle.penup()
mirrorTurtle.penup()
turtle.forward(40)
turtle.dot(20, "red")
mirrorTurtle.dot(10, "blue")
turtle.forward(1)
mirrorTurtle.setpos(-turtle.xcor(), -turtle.ycor())
ontimer(move, 1000 // FRAMES_PER_SECOND)
def start():
global moving
moving = True
move()
def stop():
global moving
moving = False
def main():
colormode(255)
global turtle
global mirrorTurtle
turtle = Turtle()
turtle.hideturtle()
mirrorTurtle.hideturtle()
onkey(turnRight, "Right")
onkey(turnLeft, "Left")
onkey(start, "Up")
onkey(stop, "Down")
listen()
if __name__ == "__main__":
main()
the issue for me is, where I have "red" and "blue" are supposed to be random colors (that still act as a mirror (ie; if the first dot typed is blue, the mirror should be blue as well).
If you search for a function that gives you a random color string, see this:
def randcolor():
return "#"+"".join([random.choice("0123456789ABCDEF") for i in range(6)]
You are very close to a solution. You need small changes to randomColor
and to move
.
In randomColor
, you have successfully created three random numbers. Now you just need to create a tuple
and return it, like so:
def randomColor():
r = randrange(256) # red component of color
g = randrange(256) # green component
b = randrange(256) # blue component
return r,g,b
Then, you need to use that random color in your call to dot()
:
mirrorTurtle.dot(10, randomColor())
Additionally, to get your program to work in my environment, I need to add a call to update()
at the end of move()
, and a call to mainloop()
at the end of main()
.
