如何乘以 python 流星对象
How multiply python meteors objects
好的，所以我正在尝试制作一款流星游戏，您必须在其中躲避流星。但我不只想要 1 颗流星，我想要多颗。那么如何将我的第一颗流星复制到更多呢？
我试过用一个函数来做更多。但它给了我一个错误。我试过使用 while 循环，所以它运行流星代码 10 次，但没有用
import turtle
import random
# meteorgame by Daniel99oslo
wn = turtle.Screen()
wn.title("Meteor")
wn.bgcolor("black")
wn.setup(width=500, height=600)
wn.tracer(0)
#Player
Player = turtle.Turtle()
Player.speed(0)
Player.shape("square")
Player.color("Blue")
Player.shapesize(stretch_wid=1, stretch_len=1)
Player.penup()
Player.goto(0, -100)
#Meteor
Meteor = turtle.Turtle()
Meteor.speed(0)
Meteor.shape("square")
Meteor.color("red")
Meteor.shapesize(stretch_wid=1, stretch_len=1)
Meteor.penup()
Meteor.goto(0, 290)
y1 = (random.randint(500,600))
y2 = Meteor.ycor()
Meteor.sety(y1)
# left/right
def Player_Left():
x = Player.xcor()
x -= 5
Player.setx(x)
def Player_Right():
x = Player.xcor()
x += 5
Player.setx(x)
# Keyboard binds a/d
wn.listen()
wn.onkeypress(Player_Left, "a")
wn.onkeypress(Player_Right, "d")
# Main game loop
while True:
wn.update()
#Meteor respawn/location
x1 = (random.randint(-230,230))
y = Meteor.ycor()
y -= 0.1
Meteor.sety(y)
if Meteor.ycor() <-300:
Meteor.sety(290)
x = Meteor.xcor()
Meteor.setx(x1)
#Meteor hit player detection
if Player.distance(Meteor) < 25:
#Code that will kill player add here
pass
如果你只是循环遍历 meteor 代码你有 10 次你仍然只会得到一个结果，因为每次循环它时变量都会被覆盖。处理此问题的一种简单方法是创建一个列表并将流星存储在其中。

另一种方法是初始化一个流星原型，然后使用它的 .clone() 方法来填充你的流星数组：
from turtle import Screen, Turtle
from random import randint
# ...
# Meteors
prototype_meteor = Turtle()
prototype_meteor.shape('square')
prototype_meteor.speed('fastest')
prototype_meteor.color('red')
prototype_meteor.penup()
prototype_meteor.setposition(randint(-230, 230), randint(250, 300))
meteors = [prototype_meteor]
for i in range(9):
meteor = prototype_meteor.clone()
meteor.setposition(randint(-230, 230), randint(250, 300))
meteors.append(meteor)
