> Hi everyone, I'm trying to create a simple maze program. When the user finishes the maze, I want to print in big letters "You Win!" and when the user hits a wall, I want the user to go back to the beginning of the maze. The problem is "collision detection" which is an advanced topic and I'm only in a beginning programming class. Is there anyway I can force the user back to the starting point when the turtle hits the wall? Thank you in advance.


Sorry about that, I realized I forgot to include the code.
So basically I have one turtle that draws the maze at the beginning and then another turtle(userTurtle) that completes the maze. When the userTurtle hits any point on the wall, I want to force userTurtle back to the start of the maze.
 Here it is:

import turtle
userTurtle = turtle.Turtle()
draw = turtle.Turtle()
scr = turtle.Screen()

def drawMaze():
    draw.pencolor("gold")
    draw.pensize(3)
    draw.penup()
    draw.goto(0,-180)
    draw.pendown()
    draw.speed(10)
    draw.setheading(180)
    draw.fd(180)
    draw.setheading(90)
    draw.fd(60)
    draw.setheading(0)
    draw.fd(120)
    draw.backward(120)
    draw.setheading(90)
    draw.fd(300)
    draw.setheading(0)
    draw.fd(120)
    draw.setheading(-90)
    draw.fd(120)
    draw.setheading(180)
    draw.fd(60)
    draw.setheading(90)
    draw.fd(60)
    draw.setheading(-90)
    draw.fd(120)
    draw.setheading(90)
    draw.fd(60)
    draw.setheading(0)
    draw.fd(120)
    draw.setheading(-90)
    draw.fd(60)
    draw.setheading(0)
    draw.fd(60)
    draw.setheading(-90)
    draw.fd(60)
    draw.backward(60)
    draw.setheading(0)
    draw.fd(60)
    draw.setheading(90)
    draw.fd(60)
    draw.penup()
    draw.setheading(180)
    draw.fd(60)
    draw.pendown()
    draw.setheading(90)
    draw.fd(60)
    draw.setheading(180)
    draw.fd(60)
    draw.setheading(90)
    draw.fd(60)
    draw.setheading(0)
    draw.fd(120)

    draw.setheading(180)
    draw.fd(60)
    draw.setheading(90)
    draw.fd(60)
    draw.backward(60)
    draw.setheading(180)
    draw.fd(60)
    draw.penup()
    draw.setheading(0)
    draw.fd(300)
    draw.pendown()
