使用说明

1、注册积分类型列表，放在GameState的
PlayerScoreSystem.RegisterInfo(InScoreList) 其中InScoreList 可参考PlayerScoreSystem.Config.ScoreList

2、在玩家加入时添加
PlayerScoreSystem.InitPlayerScoreData(PlayerKey)

3、绑定得分表的更新函数，更新函数内可以设置同步参数，参数放置GameState内
PlayerScoreSystem.BindChangeScoreDataCallBack(Func, Obj)
刷新绑定的案例：
(1)GameState加入同步参数PlayerScoreDatas

(2)GameState的BeginPlay函数内加入
if UGCGameSystem.IsServer() then
    -- 绑定更新积分的函数
    PlayerScoreSystem.BindChangeScoreDataCallBack(self.UpdateAllPlayerScoreDatas, self)
end

(3)加入UpdateAllPlayerScoreDatas函数
function UGCGameState:UpdateAllPlayerScoreDatas()
    self.PlayerScoreDatas = PlayerScoreSystem.GetPlayerScoreDatas()
end

(4)加入UpdateAllPlayerScoreDatas函数
function UGCGameState:UpdateAllPlayerScoreDatas()
    self.PlayerScoreDatas = PlayerScoreSystem.GetPlayerScoreDatas()
end

(5)加入OnRep_PlayerScoreDatas函数
function UGCGameState:OnRep_PlayerScoreDatas()
    PlayerScoreSystem.SetPlayerScoreDatas(self.PlayerScoreDatas)
    UGCEventSystem.SendEvent(EventEnum.UpdatePlayerScoreData)
end

-------------------------------------------------------------------------------------------

常用函数 -----------

--- Server 重置所有玩家的积分信息
PlayerScoreSystem.ResetAllPlayerScoreData()

--- Server 增加玩家积分
PlayerScoreSystem.AddPlayerScoreData(PlayerKey, ScoreType, AddVal)

--- Server 设置玩家积分
PlayerScoreSystem.SetPlayerScoreDataFromType(PlayerKey, ScoreType, Val)

--- Server or Client 获取玩家积分信息
---@return number
PlayerScoreSystem.GetPlayerScoreDataFromType(PlayerKey, ScoreType)

--- Server or Client 获取玩家得分 返回: ∑得分类型×类型对应得分
---@return number
PlayerScoreSystem.GetPlayerScore(PlayerKey)

--- Server or Client 获取玩家排名 InPlayerKeys:所需排名的PlayerKeys,若为nil则全部一起排名
---@return "table {PlayerKey, ...}"
PlayerScoreSystem.GetRank(InPlayerKeys)

--- Server or Client 获取队伍的玩家排名
---@return "table {[TeamID] = {PlayerKey, ...}, ...}"
PlayerScoreSystem.GetTeamRank()

--- Server 刷新或重设PlayerScoreSystem内的玩家TeamID
PlayerScoreSystem.UpdatePlayerTeamID(PlayerKey, TeamID)




-- 特殊情况需要用的函数 -----------

--- Server 移除玩家得分信息 NeedNotify是否通知更新    这个比较少用，用于有玩家退出时再进行补人的操作，放在PlayerExit内调用
PlayerScoreSystem.RemovePlayerScoreInfo(PlayerKey, NeedNotify)

--- Server 清除退出的玩家得分信息
PlayerScoreSystem.ClearExitPlayer()

]]

PlayerScoreSystem = PlayerScoreSystem or {}

PlayerScoreSystem.Config = {}


-- Config ----------------------------------------------------------------
PlayerScoreSystem.Config.EScoreType = {
    Kills = 1,
    Assists = 2,
    Deaths = 3,
}

--- Key值对应得分类型，Value值对应该类型每点所获得的积分
PlayerScoreSystem.Config.ScoreList = {
    [PlayerScoreSystem.Config.EScoreType.Kills] = 2;
    [PlayerScoreSystem.Config.EScoreType.Assists] = 1;
    [PlayerScoreSystem.Config.EScoreType.Deaths] = 0;
}
-- Config End ------------------------------------------------------------

-- Params ----------------------------------------------------------------
-- 得分类型对应的分数 [ScoreType] = Score
PlayerScoreSystem.ScoreList = {};
-- 得分类型
PlayerScoreSystem.ScoreType = {};
-- 玩家得分信息 [PlayerKey] = {[ScoreType] = Score, ...} 额外附加 TeamID(PlayerScoreSystem.PlayerScoreDatas[PlayerKey].TeamID)
PlayerScoreSystem.PlayerScoreDatas = {};
-- Params End ------------------------------------------------------------


--- 注册积分类型列表
---@param InScoreList 可参考PlayerScoreSystem.Config.ScoreList
function PlayerScoreSystem.RegisterInfo(InScoreList)
    if type(InScoreList) ~= "table" then
        UGCLogSystem.LogError("[PlayerScoreSystem_RegisterInfo] InScoreType 类型错误")
    end

    PlayerScoreSystem.ScoreList = InScoreList

    UGCLogSystem.LogTree("[PlayerScoreSystem_RegisterInfo] ScoreType", PlayerScoreSystem.ScoreType)
    UGCLogSystem.LogTree("[PlayerScoreSystem_RegisterInfo] ScoreList", PlayerScoreSystem.ScoreList)

end

--- Server or Client
--- 获取得分信息
function PlayerScoreSystem.GetPlayerScoreDatas()
    return PlayerScoreSystem.PlayerScoreDatas
end

--- Server
--- 设置全部的得分信息  此操作不进行函数回调，因为有可能是GameState的参数传进来的所以有可能导致死循环
function PlayerScoreSystem.SetPlayerScoreDatas(InPlayerScoreDatas)
    PlayerScoreSystem.PlayerScoreDatas = InPlayerScoreDatas
end

--- Server
--- 绑定GameState的更新函数，简化其他操作，所以只能绑一个
function PlayerScoreSystem.BindChangeScoreDataCallBack(Func, Obj)
    PlayerScoreSystem.ChangeScoreDataCallBackFunc = Func
    PlayerScoreSystem.ChangeScoreDataCallBackObj = Obj
end

--- Server
--- 通知回调
function PlayerScoreSystem.NotifyChangeScoreDataCallBack()
    if PlayerScoreSystem.ChangeScoreDataCallBackFunc then
        if PlayerScoreSystem.ChangeScoreDataCallBackObj then
            PlayerScoreSystem.ChangeScoreDataCallBackFunc(PlayerScoreSystem.ChangeScoreDataCallBackObj)
        else
            PlayerScoreSystem.ChangeScoreDataCallBackFunc()
        end
    end
end

--- Server
--- 初始化玩家的积分信息，也可作为重置函数使用
function PlayerScoreSystem.InitPlayerScoreData(PlayerKey, IsReset)
    if PlayerScoreSystem.PlayerScoreDatas[PlayerKey] == nil or IsReset then
        -- 初始化列表
        PlayerScoreSystem.PlayerScoreDatas[PlayerKey] = {}
        -- 初始化信息
        for i, v in pairs(PlayerScoreSystem.ScoreType) do
            PlayerScoreSystem.PlayerScoreDatas[PlayerKey][v] = 0
        end
        -- 设置队伍ID
        PlayerScoreSystem.PlayerScoreDatas[PlayerKey].TeamID = UGCPlayerStateSystem.GetTeamID(PlayerKey)
        UGCLogSystem.Log("[PlayerScoreSystem_InitPlayerScoreData] TeamID:%s", tostring(PlayerScoreSystem.PlayerScoreDatas[PlayerKey].TeamID))
        -- 更新函数回调
        PlayerScoreSystem.NotifyChangeScoreDataCallBack()
    end
end

        PlayerScoreSystem.PlayerScoreDatas[PlayerKey].TeamID = UGCPlayerStateSystem.GetTeamID(PlayerKey)
    end
