The levels program - Answers
Here is the final code. You can easily copy and paste this straight into Python's Idle and run it from there.
import turtle, sys
#Initialise the variables
size = 0
colour= ""
speed= 0
#Draw the window you will play the game in
window = turtle.Screen()
window.bgcolor("lightyellow")
window.setup(800, 800)
#Create a turtle object called Fred
Fred = turtle.Turtle()
#Draw a dot and move it across the screen
def alien(size, colour, speed):
Fred.ht()
Fred.up()
Fredx = -370
Fredy = 0
Fred.setpos(Fredx, Fredy)
while Fred.xcor()< 360:
window.delay(speed)
Fredx = Fredx + 10
Fred.setpos(Fredx, Fredy)
Fred.dot(size, colour)
#Display a menu. Player selects option.
level = input("""
Please select a level:
1 = Easy
2 = Medium
3 = Hard
""")
print("You have selected level",level)
#Load up values depending on level selected.
if int(level) == 1:
size = 100
colour = "blue"
speed = 25
if int(level) == 2:
size = 30
colour = "red"
speed = 10
if int(level) == 3:
size = 10
colour = "black"
speed = 1
