我试图在C#中用我的数据内联声明一个delegate,但似乎无法编译。我希望有人能帮我(重新)架构一下我的思路或代码。
我的目标是在一个在线游戏中创建不同的玩家类型。 每个玩家类型都有他们所采用的策略。这个策略是通过调用一个内联async函数来实现的,这个函数可能会调用HTTP REST资源作为IQueryable评估的一部分。
问题:什么是可维护的方式?
EvaluateTurn()
每一个人的代表 AIPlayer
类型?将会增加更多的玩家类型,并? IQueryable
以成为针对CosmosDB、AzureTable、SQL、内存数组等的延迟执行Linq查询。
public class AIPlayer
{
public string PlayerPersonaName { get; set; }
public string Description { get; set; }
public delegate int EvaluateTurn(IQueryable<GameplayRound> playHistory);
}
public List<AIPlayer> CreateDefaultPersonas()
{
var ret = new List<AIPlayer>();
ret.Add(new AIPlayer()
{
PlayerPersonaName = "CopyCat" ,
Description = "Hello! I start with Cooperate, and afterwards, I just copy whatever you did in the last round. Meow",
});
ret.Add(new AIPlayer() {
PlayerPersonaName = "Grudger" ,
Description = "Listen, pardner. I'll start cooperatin', and keep cooperatin', but if y'all ever cheat me, I'LL CHEAT YOU BACK 'TIL THE END OF TARNATION."
});
ret.Add(new AIPlayer() {
PlayerPersonaName = "AlwaysCheat",
Description = "the strong shall eat the weak"
});
ret.Add(new AIPlayer() {
PlayerPersonaName = "AlwaysCooperate",
Description = "Let's be best friends! <3"
});
ret.Add(new AIPlayer() {
PlayerPersonaName = "Detective",
Description = "First: I analyze you. I start: Cooperate, Cheat, Cooperate, Cooperate. If you cheat back, I'll act like Copycat. If you never cheat back, I'll act like Always Cheat, to exploit you. Elementary, my dear Watson."
});
ret.Add(new AIPlayer()
{
PlayerPersonaName = "CopyKitten",
Description = "Hello! I'm like Copycat, except I Cheat back only after you Cheat me twice in a row. After all, the first one could be a mistake! Purrrrr",
});
ret.Add(new AIPlayer()
{
PlayerPersonaName = "Simpleton",
Description = "hi i try start cooperate. if you cooperate back, i do same thing as last move, even if it mistake. if you cheat back, i do opposite thing as last move, even if it mistake.",
});
ret.Add(new AIPlayer()
{
PlayerPersonaName = "Random",
Description = "Monkey robot! Ninja pizza tacos! lol i'm so random (Just plays Cheat or Cooperate randomly with a 50 / 50 chance)",
});
return ret;
}
delegate是一个类型,你需要声明一个该类型的属性。
public class AIPlayer
{
public string PlayerPersonaName { get; set; }
public string Description { get; set; }
public EvaluateTurn Evaluation { get; set; }
public delegate int EvaluateTurn(IQueryable<GameplayRound> playHistory);
}
Then:
new AIPlayer()
{
PlayerPersonaName = "CopyCat" ,
Description = "Hello! I start with Cooperate, and afterwards, I just copy whatever you did in the last round. Meow",
Evaluation = playHistory => 1
};
或者你可以直接使用 Func
为简洁起见。
public class AIPlayer
{
public string PlayerPersonaName { get; set; }
public string Description { get; set; }
public Func<IQueryable<GameplayRound>, int> Evaluation { get; set; }
}
