Making a Race game

This project was to enhance my understanding of OOP and the modules in python.

This project is done by adjusting the speeds of each object at random. Something I didn't totally get at first was how to adjust the speed. I thought I was to change the speed by changing the speed method. However, I just needed to set the amount the object goes forward by.

Also, I underestimated the capabilities of for loops. This will be further elaborated on later on.

from turtle import Turtle, Screen

import random

screen = Screen()

screen.setup(width = 500, height = 400)

user_bet = screen.textinput(title = 'Make your bet', prompt= 'Which turtle do you think will win? Enter a color:')

colors = ['red', 'blue', 'yellow', 'purple','orange', 'black']

y_coordinates = [-150, -100, -50, 0, 50, 100]

is_game_on = False

turtles = []

for _ in range(6):

    tim = Turtle(shape= 'turtle')

    tim.color(colors[_])

    tim.penup()

    tim.goto(x=-230, y = y_coordinates[_])

    turtles.append(tim)

if user_bet:

    is_game_on = True

while is_game_on:

    for _ in turtles:

        distance = random.randint(1, 10)

        _.forward(distance)

        if _.xcor() >= 210:

            winning_color = _.pencolor()

            is_game_on = False

if winning_color.lower() == user_bet.lower():

    print('You won')

else:

    print('You lost')

The turtle module is something offered by python. It enables the user to draw and show things on the interface. This is quite the change as I have not been able to really show things on the interface.

In the part 'for _ in turtles' I initially wrote 6 independent turtles. This is time-consuming and ineffective. By using the for loop I could repeat the loop until I had 6 turtles, tweaking little elements so that each turtle's position differed.

Things learned

• from filename import *

  #this imports all classes from the file

• from turtle import Turtle

  tim= Turtle()

  
  

  import turtle as t

  tim = t.Turtle()

• if try to install pack that isn't installed, can actually install by clicking on some shortkeys

• if you use function as an argument, you don't have to add parentheses at the end.

  def move():

      tim.forward(10)

  screen.onkey('space', move)

• higher order functions : functions that can work with other functions

• event listeners: waits for input of keys

  
  

  screen.listen() - preset

  screen.onkey(func, key)

• setting a new heading in turtle:

  
  

  tim= Turtle()

  new_heading = tim.heading() + 10

  tim.setheading(new_heading)

• with classes, you can create multiple instances.
