**结构说明**:

- **Core**: 核心架构和基础设施,不依赖其他层
- **Domain**: 领域模型和业务规则,纯业务逻辑
- **Application**: 应用服务和用例,协调领域对象
- **Infrastructure**: 技术实现,如数据访问、资源加载
- **Presentation**: 表现层,处理用户交互和显示
- **Modules**: 功能模块,封装完整的功能单元

### 1.2 创建核心架构

```csharp
using GFramework.Core.architecture;
using GFramework.Core.Abstractions.architecture;

namespace MyGame.Core.Architecture
{
    /// <summary>
    /// 游戏主架构
    /// </summary>
    public class GameArchitecture : Architecture
    {
        public static IArchitecture Interface { get; private set; }

        protected override void Init()
        {
            Interface = this;

            Console.WriteLine("初始化游戏架构...");
        }

        protected override void InstallModules()
        {
            // 模块将在步骤 3 中安装
            Console.WriteLine("安装功能模块...");
        }
    }
}
```

## 步骤 2: 架构分层

实现清晰的分层架构,确保各层职责明确,依赖关系单向。

### 2.1 领域层 - 玩家模型

```csharp
using GFramework.Core.model;
using GFramework.Core.property;

namespace MyGame.Domain.Models.Player
{
    /// <summary>
    /// 玩家数据模型
    /// </summary>
    public class PlayerModel : AbstractModel
    {
        // 基础属性
        public BindableProperty<string> Name { get; } = new("Player");
        public BindableProperty<int> Level { get; } = new(1);
        public BindableProperty<int> Experience { get; } = new(0);

        // 战斗属性
        public BindableProperty<int> Health { get; } = new(100);
        public BindableProperty<int> MaxHealth { get; } = new(100);
        public BindableProperty<int> Mana { get; } = new(50);
        public BindableProperty<int> MaxMana { get; } = new(50);

        // 位置信息
        public BindableProperty<float> PositionX { get; } = new(0f);
        public BindableProperty<float> PositionY { get; } = new(0f);
        public BindableProperty<float> PositionZ { get; } = new(0f);

        protected override void OnInit()
        {
            Console.WriteLine($"玩家模型初始化: {Name.Value}");

            // 监听等级变化
            Level.Register(OnLevelChanged);
        }

        private void OnLevelChanged(int newLevel)
        {
            Console.WriteLine($"玩家升级到 {newLevel} 级");

            // 升级时恢复生命值和法力值
            Health.Value = MaxHealth.Value;
            Mana.Value = MaxMana.Value;
        }

        /// <summary>
        /// 受到伤害
        /// </summary>
        public void TakeDamage(int damage)
        {
            Health.Value = Math.Max(0, Health.Value - damage);

            if (Health.Value == 0)
            {
                Console.WriteLine("玩家死亡");
            }
        }

        /// <summary>
        /// 获得经验
        /// </summary>
        public void GainExperience(int exp)
        {
            Experience.Value += exp;

            // 检查是否升级
            int expNeeded = GetExperienceForNextLevel();
            if (Experience.Value >= expNeeded)
            {
                LevelUp();
            }
        }

        private void LevelUp()
        {
            Level.Value++;
            Experience.Value = 0;

            // 提升属性
            MaxHealth.Value += 10;
            MaxMana.Value += 5;
        }

        private int GetExperienceForNextLevel()
        {
            return Level.Value * 100;
        }
    }
}
```

### 2.2 领域层 - 领域事件

```csharp
using GFramework.Core.Abstractions.events;

namespace MyGame.Domain.Events.Player
{
    /// <summary>
    /// 玩家升级事件
    /// </summary>
    public record PlayerLevelUpEvent(int NewLevel, int OldLevel) : IEvent;

    /// <summary>
    /// 玩家生命值变化事件
    /// </summary>
    public record PlayerHealthChangedEvent(int NewHealth, int OldHealth, int MaxHealth) : IEvent;

    /// <summary>
    /// 玩家死亡事件
    /// </summary>
    public record PlayerDeathEvent(string Reason) : IEvent;

    /// <summary>
    /// 玩家位置变化事件
    /// </summary>
    public record PlayerPositionChangedEvent(float X, float Y, float Z) : IEvent;
}
```

### 2.3 应用层 - 玩家系统

```csharp
using GFramework.Core.system;
using GFramework.Core.Abstractions.events;
using MyGame.Domain.Models.Player;
using MyGame.Domain.Events.Player;

namespace MyGame.Application.Systems.Player
{
    /// <summary>
    /// 玩家管理系统
    /// </summary>
    public class PlayerSystem : AbstractSystem
    {
        private PlayerModel _playerModel;
        private IEventBus _eventBus;

        protected override void OnInit()
        {
            // 获取依赖
            _playerModel = this.GetModel<PlayerModel>();
            _eventBus = this.GetService<IEventBus>();

            // 监听玩家属性变化
            _playerModel.Level.Register(OnLevelChanged);
            _playerModel.Health.Register(OnHealthChanged);

            Console.WriteLine("玩家系统初始化完成");
        }

        private void OnLevelChanged(int newLevel)
        {
            // 发布升级事件
            _eventBus.Publish(new PlayerLevelUpEvent(newLevel, newLevel - 1));
        }

        private void OnHealthChanged(int newHealth)
        {
            // 发布生命值变化事件
            _eventBus.Publish(new PlayerHealthChangedEvent(
                newHealth,
                _playerModel.Health.Value,
                _playerModel.MaxHealth.Value
            ));

            // 检查死亡
            if (newHealth == 0)
            {
                _eventBus.Publish(new PlayerDeathEvent("生命值耗尽"));
            }
        }

        /// <summary>
        /// 移动玩家
        /// </summary>
        public void MovePlayer(float x, float y, float z)
        {
            _playerModel.PositionX.Value = x;
            _playerModel.PositionY.Value = y;
            _playerModel.PositionZ.Value = z;

            _eventBus.Publish(new PlayerPositionChangedEvent(x, y, z));
        }

        /// <summary>
        /// 治疗玩家
        /// </summary>
        public void HealPlayer(int amount)
        {
            int newHealth = Math.Min(
                _playerModel.Health.Value + amount,
                _playerModel.MaxHealth.Value
            );

            _playerModel.Health.Value = newHealth;
            Console.WriteLine($"玩家恢复 {amount} 点生命值");
        }
    }
}
```

### 2.4 应用层 - 命令模式

```csharp
using GFramework.Core.command;
using MyGame.Domain.Models.Player;

namespace MyGame.Application.Commands.Player
{
    /// <summary>
    /// 移动玩家命令
    /// </summary>
    public class MovePlayerCommand : AbstractCommand
    {
        private readonly float _x;
        private readonly float _y;
        private readonly float _z;
        private float _oldX;
        private float _oldY;
        private float _oldZ;

        public MovePlayerCommand(float x, float y, float z)
        {
            _x = x;
            _y = y;
            _z = z;
        }

        protected override void OnExecute()
        {
            var playerModel = this.GetModel<PlayerModel>();

            // 保存旧位置(用于撤销)
            _oldX = playerModel.PositionX.Value;
            _oldY = playerModel.PositionY.Value;
            _oldZ = playerModel.PositionZ.Value;

            // 移动到新位置
            playerModel.PositionX.Value = _x;
            playerModel.PositionY.Value = _y;
            playerModel.PositionZ.Value = _z;

            Console.WriteLine($"玩家移动到 ({_x}, {_y}, {_z})");
        }

        protected override void OnUndo()
        {
            var playerModel = this.GetModel<PlayerModel>();

            // 恢复旧位置
            playerModel.PositionX.Value = _oldX;
            playerModel.PositionY.Value = _oldY;
            playerModel.PositionZ.Value = _oldZ;

            Console.WriteLine($"撤销移动,返回 ({_oldX}, {_oldY}, {_oldZ})");
        }
    }
}
```

## 步骤 3: 模块化设计

使用 IArchitectureModule 将相关功能封装成独立模块。

### 3.1 创建玩家模块

```csharp
using GFramework.Core.Abstractions.architecture;
using MyGame.Domain.Models.Player;
using MyGame.Application.Systems.Player;

namespace MyGame.Modules.PlayerModule
{
    /// <summary>
    /// 玩家功能模块
    /// </summary>
    public class PlayerModule : IArchitectureModule
    {
        public string Name => "PlayerModule";
        public string Version => "1.0.0";

        public void Install(IArchitecture architecture)
        {
            Console.WriteLine($"安装模块: {Name} v{Version}");

            // 注册玩家相关的 Model
            architecture.RegisterModel(new PlayerModel());

            // 注册玩家相关的 System
            architecture.RegisterSystem(new PlayerSystem());
            architecture.RegisterSystem(new PlayerLevelSystem());

            Console.WriteLine($"模块 {Name} 安装完成");
        }

        public void Uninstall(IArchitecture architecture)
        {
            Console.WriteLine($"卸载模块: {Name}");

            // 清理资源
            // 注意: GFramework 会自动处理组件的清理
        }
    }

    /// <summary>
    /// 玩家等级系统
    /// </summary>
    public class PlayerLevelSystem : AbstractSystem
    {
        protected override void OnInit()
        {
            var playerModel = this.GetModel<PlayerModel>();

            // 监听升级事件
            playerModel.Level.Register(level =>
            {
                Console.WriteLine($"等级系统: 玩家达到 {level} 级");
                CalculateStats(level);
            });
        }

        private void CalculateStats(int level)
        {
            // 根据等级计算属性
            Console.WriteLine($"重新计算 {level} 级的属性");
        }
    }
}
```

### 3.2 创建战斗模块

```csharp
using GFramework.Core.Abstractions.architecture;
using GFramework.Core.system;
using MyGame.Domain.Models.Player;

namespace MyGame.Modules.CombatModule
{
    /// <summary>
    /// 战斗功能模块
    /// </summary>
    public class CombatModule : IArchitectureModule
    {
        public string Name => "CombatModule";
        public string Version => "1.0.0";

        public void Install(IArchitecture architecture)
        {
            Console.WriteLine($"安装模块: {Name} v{Version}");

            // 注册战斗系统
            architecture.RegisterSystem(new CombatSystem());
            architecture.RegisterSystem(new SkillSystem());
            architecture.RegisterSystem(new DamageCalculationSystem());

            Console.WriteLine($"模块 {Name} 安装完成");
        }

        public void Uninstall(IArchitecture architecture)
        {
            Console.WriteLine($"卸载模块: {Name}");
        }
    }

    /// <summary>
    /// 战斗系统
    /// </summary>
    public class CombatSystem : AbstractSystem
    {
        private PlayerModel _playerModel;

        protected override void OnInit()
        {
            _playerModel = this.GetModel<PlayerModel>();
            Console.WriteLine("战斗系统初始化完成");
        }

        /// <summary>
        /// 攻击目标
        /// </summary>
        public void Attack(string targetName, int damage)
        {
            Console.WriteLine($"玩家攻击 {targetName},造成 {damage} 点伤害");

            // 获取伤害计算系统
            var damageSystem = this.GetSystem<DamageCalculationSystem>();
            int finalDamage = damageSystem.CalculateDamage(damage);

            Console.WriteLine($"最终伤害: {finalDamage}");
        }
    }

    /// <summary>
    /// 技能系统
    /// </summary>
    public class SkillSystem : AbstractSystem
    {
        private readonly Dictionary<string, float> _cooldowns = new();

        protected override void OnInit()
        {
            Console.WriteLine("技能系统初始化完成");
        }

        /// <summary>
        /// 使用技能
        /// </summary>
        public bool UseSkill(string skillName, int manaCost)
        {
            var playerModel = this.GetModel<PlayerModel>();

            // 检查法力值
            if (playerModel.Mana.Value < manaCost)
            {
                Console.WriteLine($"法力值不足,无法使用 {skillName}");
                return false;
            }

            // 检查冷却
            if (_cooldowns.ContainsKey(skillName))
            {
                Console.WriteLine($"技能 {skillName} 冷却中");
                return false;
            }

            // 消耗法力值
            playerModel.Mana.Value -= manaCost;

            Console.WriteLine($"使用技能: {skillName}");
            return true;

        }
    }
}
```

## 步骤 4: 依赖管理

使用 IoC 容器管理依赖关系,实现松耦合设计。

### 4.1 注册服务

```csharp
using GFramework.Core.architecture;
using GFramework.Core.Abstractions.architecture;
using GFramework.Core.ioc;
using MyGame.Modules.PlayerModule;
using MyGame.Modules.CombatModule;
using MyGame.Modules.InventoryModule;

namespace MyGame.Core.Architecture
{
    /// <summary>
    /// 游戏主架构(完整版)
    /// </summary>
    public class GameArchitecture : Architecture
    {
        public static IArchitecture Interface { get; private set; }

        protected override void Init()
        {
            Interface = this;

            Console.WriteLine("=== 初始化游戏架构 ===");

            // 注册核心服务
            RegisterCoreServices();
        }

        protected override void InstallModules()
        {
            Console.WriteLine("\n=== 安装功能模块 ===");

            // 按依赖顺序安装模块
            InstallModule(new PlayerModule());      // 基础模块
            InstallModule(new InventoryModule());   // 依赖玩家模块
            InstallModule(new CombatModule());      // 依赖玩家模块
            InstallModule(new QuestModule());       // 依赖多个模块

            Console.WriteLine("\n=== 所有模块安装完成 ===");
        }

        /// <summary>
        /// 注册核心服务
        /// </summary>
        private void RegisterCoreServices()
        {
            // 注册日志服务
            var loggerFactory = new ConsoleLoggerFactory();
            RegisterService<ILoggerFactory>(loggerFactory);

            // 注册配置服务
            var configManager = new ConfigurationManager();
            RegisterService<IConfigurationManager>(configManager);

            // 注册资源管理器
            var resourceManager = new ResourceManager();
            RegisterService<IResourceManager>(resourceManager);

            Console.WriteLine("核心服务注册完成");
        }
    }

    // 简化的服务实现示例
    public interface ILoggerFactory { }
    public class ConsoleLoggerFactory : ILoggerFactory { }

    public interface IConfigurationManager { }
    public class ConfigurationManager : IConfigurationManager { }

    public interface IResourceManager { }
    public class ResourceManager : IResourceManager { }
}
```

### 4.2 创建任务模块(展示模块间依赖)

```csharp
using GFramework.Core.Abstractions.architecture;
using GFramework.Core.model;
using GFramework.Core.system;
using MyGame.Domain.Models.Player;
using MyGame.Modules.InventoryModule;

namespace MyGame.Modules.QuestModule
{
    /// <summary>
    /// 任务功能模块
    /// </summary>
    public class QuestModule : IArchitectureModule
    {
        public string Name => "QuestModule";
        public string Version => "1.0.0";

        public void Install(IArchitecture architecture)
        {
            Console.WriteLine($"安装模块: {Name} v{Version}");

            // 注册任务模型和系统
            architecture.RegisterModel(new QuestModel());
            architecture.RegisterSystem(new QuestSystem());

            Console.WriteLine($"模块 {Name} 安装完成");
        }

        public void Uninstall(IArchitecture architecture)
        {
            Console.WriteLine($"卸载模块: {Name}");
        }
    }

        public string Description { get; set; }
        public bool IsCompleted { get; set; }
        public int RewardExp { get; set; }
        public int RewardGold { get; set; }
    }

    /// <summary>

        protected override void OnInit()
        {
            Console.WriteLine("任务模型初始化完成");
        }

        public void AddQuest(Quest quest)

                Console.WriteLine($"完成任务: {quest.Name}");
            }
        }

        public IReadOnlyList<Quest> GetActiveQuests() => _activeQuests.AsReadOnly();
    }

    /// <summary>
    /// 任务系统(依赖多个模块)
    /// </summary>
    public class QuestSystem : AbstractSystem
    {
        private QuestModel _questModel;
        private PlayerModel _playerModel;
        private InventoryModel _inventoryModel;

        protected override void OnInit()
        {
            // 获取依赖的模型
            _questModel = this.GetModel<QuestModel>();
            _playerModel = this.GetModel<PlayerModel>();
            _inventoryModel = this.GetModel<InventoryModel>();

            Console.WriteLine("任务系统初始化完成");
        }

        /// <summary>
        /// 完成任务并发放奖励
        /// </summary>
        public void CompleteQuest(int questId)
        {
            var quest = _questModel.GetActiveQuests()
                .FirstOrDefault(q => q.Id == questId);

            if (quest == null)
            {

                return;
            }

            // 标记任务完成
            _questModel.CompleteQuest(questId);

            // 发放奖励
            GiveRewards(quest);
        }

        private void GiveRewards(Quest quest)
        {
            Console.WriteLine($"\n=== 任务奖励 ===");

            // 经验奖励
            if (quest.RewardExp > 0)

            }

            // 金币奖励
            if (quest.RewardGold > 0)
            {
                _inventoryModel.Gold.Value += quest.RewardGold;
                Console.WriteLine($"获得金币: {quest.RewardGold}");
            }

            Console.WriteLine("=================\n");
        }
    }
}
```

## 步骤 5: 代码组织

建立清晰的代码组织规范,提高代码可读性和可维护性。

### 5.1 命名规范

```csharp
namespace MyGame.Core.Constants
{
    /// <summary>
    /// 游戏常量定义
    /// </summary>
    public static class GameConstants
    {
        // 游戏配置

        public const string GameVersion = "1.0.0";

        // 玩家配置
        public const int DefaultPlayerLevel = 1;
        public const int MaxPlayerLevel = 100;
        public const int DefaultHealth = 100;
        public const int DefaultMana = 50;

        // 库存配置
        public const int DefaultInventorySlots = 50;
        public const int MaxInventorySlots = 200;

        // 战斗配置
        public const float BaseDamageMultiplier = 1.0f;
        public const float CriticalDamageMultiplier = 2.0f;
    }

    /// <summary>
    /// 层级常量
    /// </summary>
    public static class LayerConstants
    {
        public const string PlayerLayer = "Player";
        public const string EnemyLayer = "Enemy";
        public const string EnvironmentLayer = "Environment";
        public const string UILayer = "UI";
    }

    /// <summary>

        // 战斗属性
        public BindableProperty<int> Health { get; } = new(100);
        public BindableProperty<int> MaxHealth { get; } = new(100);

        #endregion

        #region Lifecycle

        protected override void OnInit()
        {

        }

        #endregion

        #region Private Methods

        private void RegisterEventHandlers()
        {
            Level.Register(OnLevelChanged);
        }

        private void OnLevelChanged(int newLevel)
        {
            Console.WriteLine($"玩家升级到 {newLevel} 级");
        }

        #endregion
    }
}
```

### 5.3 扩展方法组织

```csharp
using GFramework.Core.Abstractions.architecture;
using MyGame.Domain.Models.Player;
