子系统

简介

子系统用于实现类似门客、情缘、子嗣等玩法逻辑，所有子系统应继承自SubSystemBase<TGrain, TSubSystem> 类型并使用 SubSystemAttribute 特性标注注入。

子系统在被初始化后拥有和包含它的Grain组件一样的生命周期，并且可以和Grain一样通过注入维护自身的 State 对象。

SubSystemBase{TGrain, TSubSystem}

    public abstract class SubSystemBase<TGrain, TSubSystem> : ISubSystemSet, ISubSystem
        where TSubSystem : SubSystemBase<TGrain, TSubSystem>
        where TGrain : GrainBase
    {
         protected SubSystemBase(IServiceProvider serviceProvider);

        protected virtual void InitPersistentStates(IServiceProvider serviceProvider);

        protected TGrain Grain { get; set; }

        protected IServiceProvider ServiceProvider { get; }

        protected abstract Task OnSetupAsync(CancellationToken arg);

        protected abstract Task OnActivate(CancellationToken arg);

        protected abstract Task OnDeactivateAsync(CancellationToken arg);

    }

    public class AvatarHeros : SubSystemBase<Avatar, AvatarHeros>
    {
        #region State
        [PropertyPersistentState("HeroEntityState", SystemStorages.RelationalListStorage)]
        private IPersistentState<HeroEntityStateV2> HeroEntityPersistentState { get; set; }
