Question

我正在尝试使用tkinter在Python中编写Tron街机游戏。我在碰撞检测方面遇到了一些问题。我的问题是，我不确定如何跟踪尾巴，玩家正在绘制他们移动的地方。我的第一个想法是每次创建一个新矩形时创建一个新列表。然后在每次移动时检查这些列表与玩家位置的比较。虽然我不确定如何编写循环，但仍会检查新列表。然后我发现可以将列表添加到另一个列表中。所以我想我可以制作一个包含矩形的所有坐标的列表，但它似乎只是在它们移动时覆盖旧坐标，而不是将其添加到它，即使我使用追加。我正试图在功能移动中做这些事情。

这就是我的代码目前的样子，没有我刚才描述的先前尝试的任何代码。如果您需要任何其他信息，请告诉我。

    del p2CoordList[0]
    canvas.move(player1, x1Move, y1Move)
    canvas.move(player2, x2Move, y2Move)

canvas.bind("<KeyPress>", moveVar)
