    if goals[count].ycor() > 240 or goals[count].ycor() < -240:
        goals[count].right(180)


        #collision checking
    if isCollision(player, goals[count]):
        goals[count].setposition(random.randint(-250, 250), random.randint(-250, 250))
        goals[count].right(random.randint(0,360))
        score += 1
        #Drwa the score on the screen
        mypen.undo()
        mypen.penup()
        mypen.hideturtle()
        mypen.setposition(-240, )
        scorestring = "Score: %s" %score
        mypen.write(scorestring, False, align="left", font=("Arial",14, "normal")

delay = raw_input("press Enter to Finish")
