public abstract class State
{
public virtual Enter(/* THIS NEED A PARAMETER */)
{
// an empty method
}
}
public class PlayerState : State
{
public override Enter(Player pl)
{
// method implementation
}
}
public class GoalkeeperState : State
{
public override Enter(Goalkeeper gk)
{
// method implementation
}
}
//EXAMPLE OF USE
public State globalState;
globalState.Enter(owner);
// OWNER CAN BE PLAYER OR GOALKEEPER
据我所知,virtual和overriden方法需要具有相同的“print”。所以这里有一个设计缺陷。所以这样的事情是可能的。我怎样才能做到这一点 ? 你会怎么做?

您可以在此处使用泛型:
public abstract class State<T>
{
public virtual Enter(T item)
{
// an empty method
}
}
public class PlayerState : State<Player>
{
public override Enter(Player pl)
{
// method implementation
}
}
public class GoalkeeperState : State<Goalkeeper>
{
public override Enter(Goalkeeper gk)
{
// method implementation
}
}

你可以定义
public override Enter(State pl)
或者,但是我不确定我是否理解你想要做的事情,这样的事情:
public class Player
{
public virtual Enter() {}
}
public class GoalKeeper : Player
{
public override Enter() {}
}
public class State
{
public List<Player> players {get; private set;}
public State() { players = new List<Player(); }
}
