unity GameFrameWork 储存数据 setting模块

变化

首先，在UI层面玩家做一些操作时，会使得某些模块的数据产生变化，比如设置模块：

        public void OnMusicMuteChanged(bool isOn)
        {
            GameEntry.Sound.Mute("Music", !isOn);
            m_MusicVolumeSlider.gameObject.SetActive(isOn);
        }

在对应的声音模块有两个：

1个是SoundExtension

2个是SoundComponent

SoundComponent常常作为SoundExtension的参数传入，上面就是这样：

namespace UnityGameFramework.Runtime
{
    public sealed partial class SoundComponent : GameFrameworkComponent
    {
        [Serializable]
        private sealed class SoundGroup
        {
            [SerializeField]
            private string m_Name = null;

            [SerializeField]
            private bool m_AvoidBeingReplacedBySamePriority = false;

            [SerializeField]
            private bool m_Mute = false;

            [SerializeField, Range(0f, 1f)]
            private float m_Volume = 1f;

            [SerializeField]
            private int m_AgentHelperCount = 1;

            public string Name
            {
                get
                {
                    return m_Name;
                }
            }

            public bool AvoidBeingReplacedBySamePriority
            {
                get
                {
                    return m_AvoidBeingReplacedBySamePriority;
                }
            }

            public bool Mute
            {
                get
                {
                    return m_Mute;
                }
            }

            public float Volume
            {
                get
                {
                    return m_Volume;
                }
            }

            public int AgentHelperCount
            {
                get
                {
                    return m_AgentHelperCount;
                }
            }
        }
    }
}

        public static void Mute(this SoundComponent soundComponent, string soundGroupName, bool mute)
        {
            if (string.IsNullOrEmpty(soundGroupName))
            {
                Log.Warning("Sound group is invalid.");
                return;
            }

            ISoundGroup soundGroup = soundComponent.GetSoundGroup(soundGroupName);
            if (soundGroup == null)
            {
                Log.Warning("Sound group '{0}' is invalid.", soundGroupName);
                return;
            }

            soundGroup.Mute = mute;

            GameEntry.Setting.SetBool(Utility.Text.Format(Constant.Setting.SoundGroupMuted, soundGroupName), mute);
            GameEntry.Setting.Save();
        }

如上所示，在赋值了soundGroup.Mute = mute了之后，

进行了

            GameEntry.Setting.SetBool(Utility.Text.Format(Constant.Setting.SoundGroupMuted, soundGroupName), mute);
            GameEntry.Setting.Save();

这样的两步储存

其中save的表达为：

        public void Save()
        {
            m_SettingManager.Save();
        }

这两部储存的具体代码被封装了，暂时看不到，但可以猜到是帮我们做了储存的封装。

加载

在一开始加载游戏时的ProcedureLaunch流程中，就进行了加载：

        private void InitSoundSettings()
        {
            GameEntry.Sound.Mute("Music", GameEntry.Setting.GetBool(Constant.Setting.MusicMuted, false));
            GameEntry.Sound.SetVolume("Music", GameEntry.Setting.GetFloat(Constant.Setting.MusicVolume, 0.3f));
            GameEntry.Sound.Mute("Sound", GameEntry.Setting.GetBool(Constant.Setting.SoundMuted, false));
            GameEntry.Sound.SetVolume("Sound", GameEntry.Setting.GetFloat(Constant.Setting.SoundVolume, 1f));
            GameEntry.Sound.Mute("UISound", GameEntry.Setting.GetBool(Constant.Setting.UISoundMuted, false));
            GameEntry.Sound.SetVolume("UISound", GameEntry.Setting.GetFloat(Constant.Setting.UISoundVolume, 1f));
            Log.Info("Init sound settings complete.");
        }

当我们加载某个界面时，会出现以下的内容，也就是从加载后的数据中获得数据：

            m_MusicMuteToggle.isOn = !GameEntry.Sound.IsMuted("Music");
            m_MusicVolumeSlider.value = GameEntry.Sound.GetVolume("Music");

            m_SoundMuteToggle.isOn = !GameEntry.Sound.IsMuted("Sound");
            m_SoundVolumeSlider.value = GameEntry.Sound.GetVolume("Sound");

            m_UISoundMuteToggle.isOn = !GameEntry.Sound.IsMuted("UISound");
            m_UISoundVolumeSlider.value = GameEntry.Sound.GetVolume("UISound");

也是在同样的地方SoundExtension，是这样的写的

        public static float GetVolume(this SoundComponent soundComponent, string soundGroupName)
        {
            if (string.IsNullOrEmpty(soundGroupName))
            {
                Log.Warning("Sound group is invalid.");
                return 0f;
            }

            ISoundGroup soundGroup = soundComponent.GetSoundGroup(soundGroupName);
            if (soundGroup == null)
            {
                Log.Warning("Sound group '{0}' is invalid.", soundGroupName);
                return 0f;
            }

            return soundGroup.Volume;
        }

总结：

除了soundExtension以外，还有UIExtension，EntityExtension，LoadDataTable，都是以自己的组件为第一个参数进行处理的静态类。

至于那些储存后的名字，可以找一个类进行列举，比如

    public static partial class Constant
    {
        public static class Setting
        {
            public const string Language = "Setting.Language";
            public const string SoundGroupMuted = "Setting.{0}Muted";
            public const string SoundGroupVolume = "Setting.{0}Volume";
            public const string MusicMuted = "Setting.MusicMuted";
            public const string MusicVolume = "Setting.MusicVolume";
            public const string SoundMuted = "Setting.SoundMuted";
            public const string SoundVolume = "Setting.SoundVolume";
            public const string UISoundMuted = "Setting.UISoundMuted";
            public const string UISoundVolume = "Setting.UISoundVolume";
        }
    }

比如我要建立自己的储存，我可以建立自己的CatComponent，然后建立一个CatExtension，在这里引用setting模块进行大部分数值的保存和加载。
