c# - How to handle class visibility/access correctly

Question

I'm designing a simple game and I'm not sure how to correctly handle the access and relations between classes. E.g:

Class Game - method Start that will initialiaze objects (fields) Player, CPUPlayer, Board.

Player/CPUPlayer contains a method "Place a pawn" but they would need to access the Board object to check for coordinates.

But they do not see the Board object. Does it mean I need to pass the Board object reference (or any other objects) in their constructor?

Answer 1

是的，如果它们依赖于该对象，则需要在创建它们时将其注入它们。构造函数是正确的地方。稍后，当你掌握了一些东西时，你可能想考虑使用像UnityBoard这样的 DI 容器，但现在，只需在它们的构造函数中接收一个实例。

Answer 2

在这种特殊情况下，它们似乎确实需要对 Board 对象的引用。如果您想对其进行过度设计，您可以创建一个专用接口 ICoordinateCheckable，在 Board 中实现它，并让 Player 在构造函数中接受此接口的实例（而不是 Board）。
