极客教程在Python中使用Turtle创建一个简单的双人游戏
TurtleMove游戏基本上是一个基于运气的游戏。在这个游戏中，两个玩家（红色和蓝色），使用自己的Turtle（对象）玩游戏。
如何玩
游戏是在预定的网格中进行的，有一些边界。
- 两位玩家将Turtle移动一个单位距离。
- 现在，双方都抛出硬币。
- 如果HEAD，那么就向右转
- 否则左转
- 现在重复1和2，直到两只Turtle都躺在边界内
用Turtle Python实现
- 首先，为网格边界创建一个Turtle屏幕对象。
- 现在，两只Turtle（红和蓝）被创造出来，每个玩家都有一只。
- 两只Turtle都使用turtle_obj.forward(50)方法移动了一个单位距离。
- 使用随机范围(0, 2)，即0代表左边，1代表右边，决定转向。
- 每一步棋后，都要检查每只Turtle的位置，如果有Turtle越过了边界，那么这只Turtle就会输掉比赛。
以下是实现：
import random
import turtle
# function to check whether turtle
# is in Screen or not
def isInScreen(win, turt):
# getting the end points of turtle screen
leftBound = -win.window_width() / 2
rightBound = win.window_width() / 2
topBound = win.window_height() / 2
bottomBound = -win.window_height() / 2
# getting the current position of the turtle
turtleX = turt.xcor()
turtleY = turt.ycor()
# variable to store whether in screen or not
stillIn = True
# condition to check whether in screen or not
if turtleX > rightBound or turtleX < leftBound:
stillIn = False
if turtleY > topBound or turtleY < bottomBound:
stillIn = False
# returning the result
return stillIn
# function to check whether both turtle have
# different position or not
def sameposition(Red, Blue):
if Red.pos() == Blue.pos():
return False
else:
return True
# main function
def main():
# screen initialization for turtle
wn = turtle.Screen()
# Turtle Red initialization
# instantiate a new turtle object
# called 'Red'
Red = turtle.Turtle()
# set pencolor as red
Red.pencolor("red")
# set pensize as 5
Red.pensize(5)
# set turtleshape as turtle
Red.shape('turtle')
pos = Red.pos()
# Turtle Blue initialization
# instantiate a new turtle object
# called 'Blue'
Blue = turtle.Turtle()
# set pencolor as blue
Blue.pencolor("blue")
# set pensize as 5
Blue.pensize(5)
# set turtleshape as turtle
Blue.shape('turtle')
# make the turtle invisible
Blue.hideturtle()
# don't draw when turtle moves
Blue.penup()
# move the turtle to a location 50
# units away from Red
Blue.goto(pos[0]+50, pos[1])
# make the turtle visible
Blue.showturtle()
# draw when the turtle moves
Blue.pendown()
# variable to store whether turtles
# are in screen or not
mT = True
jT = True
# loop for the game
while mT and jT and sameposition(Red, Blue):
# coin flip for Red
coinRed = random.randrange(0, 2)
# angle for Red
# random.randrange(0, 180)
angleRed = 90
# condition for left or right
# based on coin
if coinRed == 0:
Red.left(angleRed)
else:
Red.right(angleRed)
# coin flip for Blue
coinBlue = random.randrange(0, 2)
# angle for Blue
# random.randrange(0, 180)

# condition for left or right based
# on coin

Blue.left(angleBlue)
else:
Blue.right(angleBlue)
# draw for Red
Red.forward(50)
# draw for Blue
Blue.forward(50)
# checking whether turtles are in the
# screen or not
mT = isInScreen(wn, Blue)
jT = isInScreen(wn, Red)
# set pencolor for Blue and Red as black
Red.pencolor("black")
Blue.pencolor("black")
# condition check for draw or win
if jT == True and mT == False:
# writing results
Red.write("Red Won", True, align="center",
font=("arial", 15, "bold"))
elif mT == True and jT == False:
# writing results

# writing results

font=("arial", 15, "bold"))
# exit on close

# Calling main function
