在我的代码中（将在长描述的末尾）我制作了一个tkinter画布游戏。到目前为止，画布上名为“播放器”的精灵向鼠标移动。当精灵“玩家”的坐标足够接近精灵“食物”的坐标时，食物将从画布上删除，然后在另一个随机位置再次创建。这也会将精灵“玩家”的大小增加1（通过在x1和y1坐标上加1）。
但我的问题是，如果没有一些非常奇怪的结果，我似乎无法创造超过1个稳定的“食物”精灵。理想情况下，我希望能够无限复制，直到我的CPU过热......但我会满足于10个精灵（但后来需要相同）。这样“玩家”精灵可以吃更多的食物。

这个Guys是我对如何复制相同精灵的最初想法的来源。但如果你自己运行它，你会发现结果是......有问题的。 请帮我把这个工作做好。

请参阅下面的答案：
from tkinter import *
import random
class App:
def __init__(self, root):
self.root = root
self.label = []
self.text = []
self.root.geometry("500x500")
self.canvas = Canvas(root, width=500, height=500)
self.button = Button(self.canvas, text="Ok", command=self.random)
self.canvas.pack(expand=True, fill="both")
self.button.pack()
def random(self):
self.label.append(Label(self.canvas, text="text"))
for i in self.label:
self.text.append(self.canvas.create_window(random.randrange(500), random.randrange(500), window=i))
root = Tk()
App(root)
root.mainloop()
在上文中，我们创建了两个list s label和text。
每次推送button时，我们都会创建一个新的label并将其存储在列表label中。然后，我们对list label进行迭代，并为列表中的每个元素创建一个新的canvas窗口，将这些窗口存储在text中以供日后使用。
这将允许您继续生产食物，直到CPU过热。
作为附注，我建议你回顾一下：

您提供了太多不相关的代码，您的问题归结为“我如何随机化画布中多个对象的位置？”然而，你已经为你的玩家角色包含了整个逻辑。
