# 敌人寻路逼近 + 攻击选择器 实现计划
|
||||
|
||||
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
|
||||
|
||||
**Goal:** 新增"寻路逼近（Approach）+ 到攻击范围内按策略选招攻击、攻击时暂停逼近"的敌人交战范式，与现有冲锋（Chase）范式并存。
|
||||
|
||||
**Architecture:** 感知系统（`PhysicsPerceptionSystem`）继续管敌人级交战状态（脱战/警戒/追逐）；每个攻击能力**自管圆形攻击触发范围**；AI 状态机（`PerceptionStateMachine`）新增 opt-in 的 `Approach↔Attack` 两态子机做决策；纯逻辑的 `EnemyAttackSelector` 从"够得着+未冷却+LOS+着地"的候选里按 `WeightedRandom`/`Priority` 选招。
|
||||
|
||||
**Tech Stack:** Unity 2D、C#、PathBerserker2d 导航、自研 BrainGraph HFSM、NUnit EditMode 测试（Unity Test Runner）。
|
||||
|
||||
**设计文档：** `Docs_Dev/superpowers/specs/2026-07-24-enemy-nav-approach-attack-design.md`
|
||||
|
||||
**通用验证方式：**
|
||||
- **编译门**：改动 C# 后，用 MCP `unity_get_compilation_errors` 确认 0 错误。
|
||||
- **EditMode 测试**：Unity 菜单 `Window > General > Test Runner > EditMode > Run All`（或运行指定类）。
|
||||
- **提交**：每个 Task 末尾 `git add <改动文件> && git commit`。提交信息用中文 + 类型前缀（`feat(enemy):`/`test(enemy):`）。
|
||||

|
||||
|
||||
## Task 1: 枚举与 SO 字段（选招/射程元数据）
|
||||
|
||||
**Files:**
|
||||
- Create: `Assets/_Game/Scripts/Enemies/Abilities/AbilityCategory.cs`
|
||||
- Create: `Assets/_Game/Scripts/Enemies/Abilities/AttackSelectionMode.cs`
|
||||
- Modify: `Assets/_Game/Scripts/Enemies/Abilities/EnemyAbilitySO.cs`
|
||||
- Modify: `Assets/_Game/Scripts/Enemies/EnemyStatsSO.cs`
|
||||
|
||||
- [ ] **Step 1: 建 AbilityCategory 枚举**
|
||||
|
||||
`AbilityCategory.cs`：
|
||||
```csharp
|
||||
namespace BaseGames.Enemies.Abilities
|
||||
{
|
||||
/// <summary>能力调度分类：攻击选择器只从 <see cref="Attack"/> 类里选招。</summary>
|
||||
public enum AbilityCategory
|
||||
{
|
||||
None, // 未分类（默认，不参与选招）
|
||||
Attack, // 攻击招式（选择器候选）
|
||||
Movement, // 位移/机动
|
||||
Utility // 辅助/增益
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
- [ ] **Step 2: 建 AttackSelectionMode 枚举**
|
||||
|
||||
`AttackSelectionMode.cs`：
|
||||
```csharp
|
||||
namespace BaseGames.Enemies.Abilities
|
||||
{
|
||||
/// <summary>多攻击选招策略。</summary>
|
||||
public enum AttackSelectionMode
|
||||
{
|
||||
WeightedRandom, // 合格集内按 weight 加权随机
|
||||
Priority // 合格集内取 priority 最高（并列取首个）
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
- [ ] **Step 3: EnemyAbilitySO 加字段**
|
||||
|
||||
在 `EnemyAbilitySO.cs` 的 `priority` 字段之后（`exclusionGroup`/`priority` 所在 Header 块末尾）追加：
|
||||
```csharp
|
||||
[Header("选招（攻击选择器用）")]
|
||||
[Tooltip("能力调度分类；攻击选择器只从 Attack 类里选招")]
|
||||
public AbilityCategory category = AbilityCategory.None;
|
||||
[Tooltip("WeightedRandom 模式下的相对权重（越大越易被选）")]
|
||||
[Min(0f)] public float weight = 1f;
|
||||
|
||||
[Header("攻击触发范围（招式自管，圆形）")]
|
||||
[Tooltip("触发半径(m)；category==Attack 时必须 > 0，否则永远够不着（Awake 报错）")]
|
||||
[Min(0f)] public float rangeRadius = 0f;
|
||||
[Tooltip("范围圆心相对敌人的偏移(m)，X 随朝向翻转")]
|
||||
public Vector2 rangeOffset = Vector2.zero;
|
||||
```
|
||||
> `EnemyAbilitySO` 已 `using UnityEngine;` 且与 `AbilityCategory` 同命名空间，无需额外 using。旧的 `preferredMinRange/preferredMaxRange` 保留不动（降级为编辑器提示）。
|
||||
|
||||
- [ ] **Step 4: EnemyStatsSO 加字段**
|
||||
|
||||
在 `EnemyStatsSO.cs` 的 `AttackCooldown` 字段附近（战斗参数区）追加：
|
||||
```csharp
|
||||
[Header("攻击选招策略")]
|
||||
[Tooltip("到攻击范围内如何从多个候选招里选一个")]
|
||||
public BaseGames.Enemies.Abilities.AttackSelectionMode attackSelectionMode
|
||||
= BaseGames.Enemies.Abilities.AttackSelectionMode.WeightedRandom;
|
||||
```
|
||||
|
||||
- [ ] **Step 5: 编译门**
|
||||
|
||||
用 MCP `unity_get_compilation_errors`，预期：0 错误。
|
||||
|
||||
- [ ] **Step 6: 提交**
|
||||
|
||||
```bash
|
||||
git add Assets/_Game/Scripts/Enemies/Abilities/AbilityCategory.cs \
|
||||
Assets/_Game/Scripts/Enemies/Abilities/AttackSelectionMode.cs \
|
||||
Assets/_Game/Scripts/Enemies/Abilities/EnemyAbilitySO.cs \
|
||||
Assets/_Game/Scripts/Enemies/EnemyStatsSO.cs
|
||||
git commit -m "feat(enemy): 攻击选招元数据(category/weight/圆形射程)与选招模式入 SO"
|
||||
```

|
||||
|
||||
## Task 2: 攻击候选契约与 InAttackRange
|
||||
|
||||
**Files:**
|
||||
- Create: `Assets/_Game/Scripts/Enemies/Abilities/IAttackCandidate.cs`
|
||||
- Modify: `Assets/_Game/Scripts/Enemies/Abilities/EnemyAbilityBase.cs`
|
||||
|
||||
- [ ] **Step 1: 建 IAttackCandidate 接口**
|
||||
|
||||
`IAttackCandidate.cs`：
|
||||
```csharp
|
||||
namespace BaseGames.Enemies.Abilities
|
||||
{
|
||||
/// <summary>
|
||||
/// 攻击选择器的候选契约。攻击类 <see cref="EnemyAbilityBase"/> 实现之；
|
||||
/// 抽象出来使 <see cref="EnemyAttackSelector"/> 可脱离 MonoBehaviour 单测。
|
||||
/// </summary>
|
||||
public interface IAttackCandidate
|
||||
{
|
||||
bool CanUse { get; } // 未冷却 + 未运行 + 存活
|
||||
bool RequiresLineOfSight { get; } // 是否需要视线（由敌人级 LOS 提供）
|
||||
bool RequiresGrounded { get; } // 是否需要着地
|
||||
float Weight { get; } // WeightedRandom 权重
|
||||
int Priority { get; } // Priority 优先级
|
||||
bool InAttackRange(); // 招式自管圆形射程内是否有玩家
|
||||
bool Execute(); // 触发本招
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
- [ ] **Step 2: EnemyAbilityBase 实现 IAttackCandidate**
|
||||
|
||||
在 `EnemyAbilityBase.cs`，把类声明改为实现接口：
|
||||
```csharp
|
||||
public abstract class EnemyAbilityBase : MonoBehaviour, IAttackCandidate
|
||||
```
|
||||
并在类内（`CanUse` 属性附近）追加以下成员（`CanUse` 已存在，接口自动匹配）：
|
||||
```csharp
|
||||
// ── IAttackCandidate（供 EnemyAttackSelector 选招）──────────────────
|
||||
public bool RequiresLineOfSight => _config != null && _config.requiresLineOfSight;
|
||||
public bool RequiresGrounded => _config != null && _config.requiresGrounded;
|
||||
public float Weight => _config != null ? _config.weight : 0f;
|
||||
public int Priority => _config != null ? _config.priority : 0;
|
||||
|
||||
/// <summary>本招圆形攻击范围内是否有玩家（招式自管其射程；LOS 复用敌人级 IsPlayerVisible）。</summary>
|
||||
public virtual bool InAttackRange()
|
||||
{
|
||||
if (_config == null || _config.rangeRadius <= 0f
|
||||
|| _enemy == null || _enemy.PlayerTransform == null) return false;
|
||||
float sign = _transform.localScale.x < 0f ? -1f : 1f;
|
||||
Vector2 origin = (Vector2)_transform.position
|
||||
+ new Vector2(_config.rangeOffset.x * sign, _config.rangeOffset.y);
|
||||
float r = _config.rangeRadius;
|
||||
return ((Vector2)_enemy.PlayerTransform.position - origin).sqrMagnitude <= r * r;
|
||||
}
|
||||
```
|
||||
> `Execute()` 与 `CanUse` 已在基类存在，直接满足接口。`_config`/`_enemy`/`_transform` 均为已有受保护字段。
|
||||
|
||||
- [ ] **Step 3: 编译门**
|
||||
|
||||
MCP `unity_get_compilation_errors`，预期 0 错误。
|
||||
|
||||
- [ ] **Step 4: 提交**
|
||||
|
||||
```bash
|
||||
git add Assets/_Game/Scripts/Enemies/Abilities/IAttackCandidate.cs \
|
||||
Assets/_Game/Scripts/Enemies/Abilities/EnemyAbilityBase.cs
|
||||
git commit -m "feat(enemy): EnemyAbilityBase 实现 IAttackCandidate 契约(自管圆形射程)"
|

## Task 3: EnemyAttackSelector（选招器）+ 单元测试（TDD）
|
||||
|

**Files:**
|

- Test: `Assets/Tests/EditMode/Enemies/EnemyAttackSelectorTests.cs`
|

- Create: `Assets/_Game/Scripts/Enemies/Abilities/EnemyAttackSelector.cs`
|

}
|

```
|
||||
|
||||
- [ ] **Step 2: 运行确认失败**
|
||||
|
||||
Test Runner 运行 `EnemyAttackSelectorTests`，预期：**编译失败**（`EnemyAttackSelector` 未定义）。
|
||||
|
||||
- [ ] **Step 3: 实现 EnemyAttackSelector**
|
||||
|
||||
`EnemyAttackSelector.cs`：
|
||||
```csharp
|
||||
using System.Collections.Generic;
|
||||
using UnityEngine;
|
||||
|
||||
namespace BaseGames.Enemies.Abilities
|

public EnemyAttackSelector(IEnumerable<IAttackCandidate> candidates)
|

public int Count => _candidates.Count;
|
||||
|

private static bool Eligible(IAttackCandidate c, bool hasLOS, bool grounded)
|
||||
=> c != null && c.CanUse && c.InAttackRange()
|

&& (!c.RequiresLineOfSight || hasLOS)
|
||||
&& (!c.RequiresGrounded || grounded);
|
||||
|
||||
public bool HasEligible(bool hasLOS, bool grounded)
|
||||
{
|
||||
for (int i = 0; i < _candidates.Count; i++)
|
||||
if (Eligible(_candidates[i], hasLOS, grounded)) return true;
|
||||
return false;
|
||||
}
|
||||
|
||||
public IAttackCandidate Select(bool hasLOS, bool grounded, AttackSelectionMode mode)
|
||||
=> mode == AttackSelectionMode.Priority
|
||||
? SelectByPriority(hasLOS, grounded)
|
||||
: SelectByWeight(hasLOS, grounded);
|
||||
|
||||
private IAttackCandidate SelectByPriority(bool hasLOS, bool grounded)
|
||||
{
|
||||
IAttackCandidate best = null;
|
||||
for (int i = 0; i < _candidates.Count; i++)
|
||||
{
|
||||
var c = _candidates[i];
|
||||
if (!Eligible(c, hasLOS, grounded)) continue;
|
||||
if (best == null || c.Priority > best.Priority) best = c; // 并列取首个
|

private IAttackCandidate SelectByWeight(bool hasLOS, bool grounded)
|
||||
{
|
||||
float total = 0f;
|
||||
for (int i = 0; i < _candidates.Count; i++)
|
||||
{
|
||||
var c = _candidates[i];
|
||||
if (Eligible(c, hasLOS, grounded)) total += Mathf.Max(0f, c.Weight);

|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
- [ ] **Step 4: 运行确认通过**
|
||||
|
||||
Test Runner 运行 `EnemyAttackSelectorTests`，预期：全部 PASS。若 `Assets/Tests/EditMode/Enemies/` 需要 `.asmdef`——不需要，EditMode 测试同属 `BaseGames.Tests.EditMode` 程序集（已引用 `BaseGames.Enemies`）。
|
||||
|
||||
- [ ] **Step 5: 提交**
|
||||
|
||||
```bash
|
||||
git add Assets/_Game/Scripts/Enemies/Abilities/EnemyAttackSelector.cs \
|
||||
Assets/Tests/EditMode/Enemies/EnemyAttackSelectorTests.cs
|
||||
git commit -m "feat(enemy): EnemyAttackSelector 选招器(射程+冷却+LOS+着地过滤,两模式选招)+单测"
|
||||
```

|
||||
|
||||
## Task 4: ICombatant 扩展 + EnemyBrainContext 实现 + FakeCombat
|
||||
|
||||
**Files:**
|
||||
- Modify: `Assets/_Game/Scripts/AI/ICombatant.cs`
|
||||
- Modify: `Assets/_Game/Scripts/Enemies/AIBrain/EnemyBrainContext.cs`
|
||||
- Modify: `Assets/Tests/EditMode/AI/Fakes/FakeAiContext.cs`
|
||||
|
||||
- [ ] **Step 1: ICombatant 加两方法**
|
||||
|
||||
在 `ICombatant.cs` 接口内追加：
|
||||
```csharp
|
||||
/// <summary>攻击选择器中是否有"够得着且未冷却"的招（供 Approach→Attack 转换）。</summary>
|
||||
bool HasEligibleAttack();
|
||||
|
||||
/// <summary>按敌人配置的选招模式选一个攻击并触发；返回是否成功触发。</summary>
|
||||
bool UseBestAttack();
|
||||
```
|
||||
|
||||
- [ ] **Step 2: EnemyBrainContext 实现**
|
||||
|
||||
在 `EnemyBrainContext.cs` 的 `// ---- ICombatant ----` 区块末尾（`InterruptAbilities` 之后）追加：
|
||||
```csharp
|
||||
public bool HasEligibleAttack()
|
||||
{
|
||||
var sel = _enemy.AttackSelector;
|
||||
if (sel == null) return false;
|
||||
return sel.HasEligible(_enemy.IsPlayerVisible(), _enemy.Movement != null && _enemy.Movement.IsGrounded);
|
||||
}
|
||||
|
||||
public bool UseBestAttack()
|
||||
{
|
||||
var sel = _enemy.AttackSelector;
|
||||
if (sel == null) return false;
|
||||
var mode = _enemy.StatsSO != null
|
||||
? _enemy.StatsSO.attackSelectionMode
|
||||
: Abilities.AttackSelectionMode.WeightedRandom;
|
||||
bool grounded = _enemy.Movement != null && _enemy.Movement.IsGrounded;
|
||||
var pick = sel.Select(_enemy.IsPlayerVisible(), grounded, mode);
|
||||
return pick != null && pick.Execute();
|
||||
}
|
||||
```
|
||||
> `_enemy.AttackSelector` 在 Task 6 添加。此处引用即可（同一提交在 Task 6 前无法编译——所以 Task 4 的编译门与 Task 6 合并验证；见 Step 5）。为避免"引用未定义成员"，**先做 Task 6 的 Step 1（加 AttackSelector 属性桩）再回本任务**——或按下方 Step 顺序：本任务与 Task 6 连续实现、统一编译门。
|
||||
|
||||
- [ ] **Step 3: FakeCombat 实现新方法**
|
||||
|
||||
在 `FakeAiContext.cs` 的 `FakeCombat` 类内追加（供状态机测试控制）：
|
||||
```csharp
|
||||
public bool Eligible; // 测试控制：是否有合格攻击
|
||||
public bool HasEligibleAttack() => Eligible;
|
||||
public bool UseBestAttack()
|
||||
{
|
||||
if (!Eligible) return false;
|
||||
Used.Add("best"); Running = "best"; return true;
|
||||
}
|
||||
```
|
||||
|
||||
- [ ] **Step 4: 检查其它 ICombatant 实现者**
|
||||
|
||||
用 Grep 搜 `: ICombatant` / `ICombatant,` 确认只有 `EnemyBrainContext` 与 `FakeCombat` 两处实现；若有其它实现者，一并补齐两方法（否则编译失败）。
|
||||
|
||||
- [ ] **Step 5: 编译门（与 Task 6 合并）**
|
||||
|
||||
因 `_enemy.AttackSelector` 依赖 Task 6，**先完成 Task 6 再统一跑编译门**。届时 MCP `unity_get_compilation_errors` 预期 0 错误。
|
||||
|
||||
- [ ] **Step 6: 提交（与 Task 6 合并提交，或本任务单独提交待 Task 6 后编译通过再提交）**
|
||||
|
||||
```bash
|
||||
git add Assets/_Game/Scripts/AI/ICombatant.cs \
|
||||
Assets/_Game/Scripts/Enemies/AIBrain/EnemyBrainContext.cs \

## Task 5: IEnemyLocomotion.Pursue + EnemyLocomotion 实现 + FakeLocomotion
|
||||
|
||||
**Files:**
|
||||
- Modify: `Assets/_Game/Scripts/AI/IEnemyLocomotion.cs`
|
||||
- Modify: `Assets/_Game/Scripts/Enemies/EnemyLocomotion.cs`
|
||||
- Modify: `Assets/Tests/EditMode/AI/Fakes/FakeLocomotion.cs`
|
||||
|
||||
- [ ] **Step 1: 接口加 Pursue**
|
||||
|
||||
在 `IEnemyLocomotion.cs` 接口内 `Approach` 之后追加：
|
||||
```csharp
|
||||
void Pursue(Vector2 target); // 寻路逼近(RunSpeed)：每帧朝 target 重寻路(底层防抖)
|
||||
```
|
||||
|
||||
- [ ] **Step 2: EnemyLocomotion 实现 Pursue**
|
||||
|
||||
在 `EnemyLocomotion.cs` 的 `MoveTo` 方法之后追加：
|
||||
```csharp
|
||||
/// <summary>
|
||||
/// 寻路逼近：设 Approach 模式 + RunSpeed，每帧朝 target 发一次寻路请求（底层 Nav 自带防抖/受阻/NavLink）。
|
||||
/// 与一次性 <see cref="MoveTo"/> 的区别：设跑速、语义为"持续追向移动目标"。供 AI 追击态每帧调用。
|

if (_enemy?.Stats != null) _enemy.Nav?.SetSpeed(_enemy.Stats.RunSpeed);
|
||||
_enemy?.MoveTo(target);
|
||||
}
|
||||
```
|
||||
|
||||
- [ ] **Step 3: FakeLocomotion 实现 Pursue**
|
||||
|
||||
在 `FakeLocomotion.cs` 类内追加：
|
||||
```csharp
|
||||
public void Pursue(Vector2 p) { CurrentMode = LocomotionMode.Approach; Calls.Add("Pursue"); }
|
||||
```
|
||||
|
||||
- [ ] **Step 4: 编译门**
|
||||
|
||||
MCP `unity_get_compilation_errors`，预期 0 错误。
|
||||
|
||||
- [ ] **Step 5: 提交**
|
||||
|
||||
```bash
|
||||
git add Assets/_Game/Scripts/AI/IEnemyLocomotion.cs \

## Task 6: EnemyBase 构建选择器 + 根因校验
|
||||
|
||||
**Files:**
|
||||
- Modify: `Assets/_Game/Scripts/Enemies/EnemyBase.cs`
|
||||
|
||||
- [ ] **Step 1: 加 AttackSelector 属性与字段**
|
||||
|
||||
在 `EnemyBase.cs` 的 `Abilities` 属性附近追加：
|
||||
```csharp
|
||||
public Abilities.EnemyAttackSelector AttackSelector => _attackSelector;
|
||||
private Abilities.EnemyAttackSelector _attackSelector;
|
||||
```
|
||||
|
||||
- [ ] **Step 2: 在 Abilities 收集后构建选择器**
|
||||
|
||||
在 `EnemyBase.Awake`（或调用 `_abilities.CollectFrom(gameObject)` 之处）**紧随其后**追加：
|
||||
```csharp
|
||||
BuildAttackSelector();
|
||||
```
|
||||
并在类内新增方法：
|
||||
```csharp
|
||||
/// <summary>
|
||||
/// 从已注册能力里收集 category==Attack 的候选，构建攻击选择器。
|
||||
/// 根因校验：攻击招 rangeRadius<=0（永远够不着）显式报错，不静默兜底（CLAUDE.md §6）。
|
||||
/// </summary>
|
||||
private void BuildAttackSelector()
|
||||
{
|
||||
var candidates = new System.Collections.Generic.List<Abilities.IAttackCandidate>();
|
||||
var all = _abilities?.All;
|
||||
if (all != null)
|
||||
{
|
||||
for (int i = 0; i < all.Count; i++)
|
||||
{
|
||||
var ab = all[i];
|
||||
if (ab == null || ab.Config == null) continue;
|
||||
if (ab.Config.category != Abilities.AbilityCategory.Attack) continue;
|
||||
if (ab.Config.rangeRadius <= 0f)
|
||||
Debug.LogError($"[EnemyBase] 攻击招 '{ab.Config.abilityId}' 的 rangeRadius<=0，" +
|
||||
"永远够不着玩家。请在其 EnemyAbilitySO 上配置攻击触发半径。", ab);
|
||||
candidates.Add(ab); // EnemyAbilityBase 实现 IAttackCandidate
|
||||
}
|
||||
}
|
||||
_attackSelector = new Abilities.EnemyAttackSelector(candidates);
|
||||
}
|
||||
```
|
||||
> 是否报"配了 ApproachAttack 却无候选"由使用该风格的敌人在其 AI/配置侧校验（本期以 rangeRadius 校验为主，够暴露最常见漏配）。`_abilities` 为已有字段（`Abilities` 属性的后备）。
|
||||
|
||||
- [ ] **Step 3: 编译门（含 Task 4 改动）**
|
||||
|
||||
MCP `unity_get_compilation_errors`，预期 0 错误（此时 Task 4 的 `_enemy.AttackSelector` 引用已可解析）。
|
||||
|
||||
- [ ] **Step 4: 运行既有 EditMode 测试确认无回归**
|
||||
|
||||
Test Runner 运行 `EnemyAttackSelectorTests` + `PerceptionStateMachineTests`（既有），预期全 PASS。
|
||||
|
||||
- [ ] **Step 5: 提交（可与 Task 4 合并）**
|
||||
|
||||
```bash
|
||||
git add Assets/_Game/Scripts/Enemies/EnemyBase.cs
|
||||
git commit -m "feat(enemy): EnemyBase 构建攻击选择器(收集 Attack 类+rangeRadius 根因校验)"

## Task 7: PerceptionStateMachine 的 ApproachAttack 拓扑 + 测试（TDD）
|
||||
|
||||
**Files:**
|
||||
- Test: `Assets/Tests/EditMode/AI/PerceptionStateMachineTests.cs`
|
||||
- Modify: `Assets/_Game/Scripts/Enemies/AIBrain/PerceptionStateMachine.cs`
|
||||
|
||||
- [ ] **Step 1: 写失败测试**
|
||||
|
||||
在 `PerceptionStateMachineTests.cs` 类内追加 ApproachAttack 构图工厂与测试：
|
||||
```csharp
|
||||
// ── ApproachAttack 交战风格 ───────────────────────────────────────
|
||||
static AiGraph GraphApproach(string entry = "Idle")
|
||||

|
||||
}
|
||||
```
|
||||
|
||||
- [ ] **Step 2: 运行确认失败**
|
||||
|
||||
Test Runner 运行 `PerceptionStateMachineTests`，预期：**编译失败**（`EngagementStyle`/`ApproachState`/`AttackState` 未定义）。
|
||||
|
||||
- [ ] **Step 3: PerceptionStateMachine 加 EngagementStyle + Config 字段**
|
||||
|
||||
在 `PerceptionStateMachine` 类内、`Config` 之上加枚举：
|
||||
```csharp
|
||||
/// <summary>交战风格：单一冲锋能力，或"寻路逼近 + 选招攻击"两态子机。</summary>
|
||||
public enum EngagementStyle { ChaseAbility, ApproachAttack }
|
||||
```
|
||||
在 `Config` 内追加字段：
|
||||
```csharp
|
||||
// 交战风格（默认冲锋能力，保持现状）；ApproachAttack 时启用 Approach↔Attack 两态子机。
|
||||
public EngagementStyle Engagement = EngagementStyle.ChaseAbility;
|
||||
public string ApproachState = "Approach";
|
||||
public string AttackState = "Attack";
|
||||
```
|
||||
|
||||
- [ ] **Step 4: 改 Add 方法：交战入口与子机分支**
|
||||
|
||||
将 `Add` 中"进追击条件"与"追击状态构建"两段改为如下（其余不变）。
|
||||
|
||||
先把 `canChase` 计算改为仅在 `ChaseAbility` 风格下应用冷却门：
|
||||
```csharp
|
||||
string chaseId = c.ChaseAbilityId;
|
||||
System.Func<IAiContext, bool> canChase;
|
||||
string chaseLabel;
|
||||
if (c.Engagement == EngagementStyle.ChaseAbility && c.PatrolBetweenChases)
|
||||
{
|
||||
canChase = x => x.Sensor.InChaseZone() && x.Combat.CanUseAbility(chaseId);
|
||||
chaseLabel = "InChaseZone+offCD";
|
||||
}
|
||||
else
|
||||
{
|
||||
canChase = x => x.Sensor.InChaseZone();
|
||||
chaseLabel = "InChaseZone";
|
||||
}
|
||||
|
||||
// 交战入口态：冲锋风格=Chase；逼近风格=Approach
|
||||
string combatEntry = c.Engagement == EngagementStyle.ApproachAttack ? c.ApproachState : c.Chase;
|
||||
```
|
||||
把 Idle/Patrol/Alert 三处的 `.To(c.Chase)` 改为 `.To(combatEntry)`：
|
||||
```csharp
|
||||
AddLocomotionState(b, c.Idle, c.IdleMode)
|
||||
.To(combatEntry).When(canChase, chaseLabel)
|
||||
.To(c.Alert).When(x => HasAlert(x) && x.Sensor.InVisionZone(), "InVision+HasAlert");
|
||||
AddLocomotionState(b, c.Patrol, c.PatrolMode)
|
||||
.To(combatEntry).When(canChase, chaseLabel)
|
||||
.To(c.Alert).When(x => HasAlert(x) && x.Sensor.InVisionZone(), "InVision+HasAlert");
|
||||
|
||||
AddLocomotionState(b, c.Alert, c.AlertMode)
|
||||
.To(combatEntry).When(canChase, chaseLabel)
|
||||
.To(c.Rest).When(x => !x.Sensor.InVisionZone(), "leftVision");
|
||||
```
|
||||
把原"追击退出"整段（`var chase = AddAbilityState(...)` 那段）替换为按风格分支：
|
||||
```csharp
|
||||
if (c.Engagement == EngagementStyle.ApproachAttack)
|
||||
{
|
||||
// Approach：寻路逼近；有招够得着→Attack；脱离全部感知→R
|
||||
b.State(c.ApproachState)
|
||||
.OnEnter(x => x.Locomotion.Pursue(x.Sensor.LastKnown))
|
||||
.Tick(x => x.Locomotion.Pursue(x.Sensor.LastKnown))
|
||||
.OnExit(x => x.Locomotion.Stop())
|
||||
.To(c.AttackState).When(x => x.Combat.HasEligibleAttack(), "attackInRange")
|
||||
.To(c.Rest).When(x => !x.Sensor.InChaseZone() && !x.Sensor.InVisionZone(), "leftAllZones");
|
||||
|
||||
// Attack：停逼近 + 选招攻击；打完回 Approach；脱离感知→R
|
||||
b.State(c.AttackState)
|
||||
.OnEnter(x => { x.Locomotion.Stop(); x.Combat.UseBestAttack(); })
|
||||
.OnExit(x => x.Combat.InterruptAbilities())
|
||||
.To(c.ApproachState).When(x => !x.Combat.IsAbilityRunning(), "attackDone")
|
||||
.To(c.Rest).When(x => !x.Sensor.InChaseZone() && !x.Sensor.InVisionZone(), "leftAllZones");
|
||||
}
|
||||
else
|
||||
{
|
||||
var chase = AddAbilityState(b, c.Chase, chaseId);
|
||||
if (c.PatrolBetweenChases)
|
||||
chase.To(c.Rest).When(x => !x.Combat.IsAbilityRunning(chaseId), "dashDone→CD");
|
||||
else
|
||||
chase.To(c.Rest).When(x => !x.Sensor.InChaseZone() && !x.Sensor.InVisionZone(), "leftAllZones");
|
||||
}
|
||||
```
|
||||
> 保留 `AddAbilityState(b, c.Death, c.DeathAbilityId);` 与全局 Died 转换不变。`combatEntry` 用于三处升级转换；`ApproachAttack` 风格下 `c.Chase` 不建态。
|
||||
|
||||
- [ ] **Step 5: 运行确认通过**
|
||||
|
||||
Test Runner 运行 `PerceptionStateMachineTests`（含既有 ChaseAbility 用例 + 新 ApproachAttack 用例），预期：全部 PASS。既有冲锋用例应不受影响（默认 `Engagement=ChaseAbility`）。
|
||||
|
||||
- [ ] **Step 6: 编译门**
|
||||
|
||||
MCP `unity_get_compilation_errors`，预期 0 错误。
|
||||
|
||||
- [ ] **Step 7: 提交**
|
||||
|
||||
```bash
|
||||
git add Assets/_Game/Scripts/Enemies/AIBrain/PerceptionStateMachine.cs \
|
||||
Assets/Tests/EditMode/AI/PerceptionStateMachineTests.cs

## Task 8: 编辑器 —— 攻击射程 Gizmo 与自检校验
|
||||
|
||||
**Files:**
|
||||
- Modify: `Assets/_Game/Scripts/Enemies/Abilities/EnemyAbilityBase.cs`（`#if UNITY_EDITOR` Gizmo）
|
||||
- Modify: 自检工具（`SOValidationRunner` 所在文件，用 Grep 定位）
|
||||
|
||||
- [ ] **Step 1: 攻击范围 Gizmo（选中敌人可见）**
|
||||
|
||||
在 `EnemyAbilityBase.cs` 末尾追加（类内，`#if UNITY_EDITOR`）：
|
||||
```csharp
|
||||
#if UNITY_EDITOR
|
||||
private void OnDrawGizmosSelected()
|
||||
{
|
||||
if (_config == null || _config.category != AbilityCategory.Attack || _config.rangeRadius <= 0f) return;
|
||||
float sign = transform.localScale.x < 0f ? -1f : 1f;
|
||||
Vector3 origin = transform.position
|
||||
+ new Vector3(_config.rangeOffset.x * sign, _config.rangeOffset.y, 0f);
|
||||
UnityEditor.Handles.color = new Color(1f, 0.4f, 0.2f, 0.9f);
|
||||
UnityEditor.Handles.DrawWireDisc(origin, Vector3.forward, _config.rangeRadius);
|
||||
UnityEditor.Handles.Label(origin, $"{_config.abilityId} range");
|
||||
}
|
||||
#endif
|
||||
```
|
||||
> `_config` 在编辑期未 Awake 也可用（SerializeField）；`_enemy`/`_transform` 不依赖，用 `transform` 直接取。
|
||||
|
||||
- [ ] **Step 2: 编译门**
|
||||
|
||||
MCP `unity_get_compilation_errors`，预期 0 错误。
|
||||
|
||||
- [ ] **Step 3: SOValidationRunner 加校验项（若存在该扩展点）**
|
||||
|
||||
用 Grep 定位 `SOValidationRunner`。若其对 `EnemyAbilitySO` 有逐资产校验钩子，追加：`category==Attack` 且 `rangeRadius<=0` → 记为校验失败（附资产路径与 `abilityId`）。若该工具无按类型钩子，则跳过本步（运行时 `BuildAttackSelector` 的 `LogError` 已兜住根因暴露），并在提交信息注明"运行时已校验，SO 静态校验待工具支持"。
|
||||
|
||||
- [ ] **Step 4: 提交**
|
||||
|
||||
```bash
|
||||
git add Assets/_Game/Scripts/Enemies/Abilities/EnemyAbilityBase.cs
|
||||
# 若改了自检工具，一并 add 其文件
|
||||
git commit -m "feat(enemy): 攻击能力射程 Gizmo + category==Attack 的 rangeRadius 自检"
|
||||
```

|
||||
## Task 9: 手动 / PlayMode 验收
|
||||
|
||||
**Files:** 无（场景内验证）
|
||||
|
||||
- [ ] **Step 1: 准备测试敌人**
|
||||
|
||||
在 `TestRoomA`（或用 ChaoFeng）：给一个敌人挂 ≥2 个攻击能力（各配 `category=Attack`、不同 `rangeRadius`/`rangeOffset`、`weight`/`priority`），其 `EnemyStatsSO.attackSelectionMode` 先设 `WeightedRandom`。其 AI 定义（`AiScript`）改用 `Engagement=ApproachAttack`（参照 `E001CaoZhiAi` 的 `PerceptionStateMachine.Add` 配置，去掉 `ChaseAbilityId`、加 `Engagement`）。确保敌人身上有寻路组件（`EnemyNavAgent`）与场景已烘焙 PB2d 导航面（含隔沟处的 Jump/Fall NavLink）。
|
||||
|
||||
- [ ] **Step 2: 验证寻路逼近**
|
||||
|
||||
进 Play，让玩家站在与敌人**隔着平台缺口**的位置且在 `aggro` 范围内。预期：敌人**沿寻路路径**（走到跳点→跳/落 NavLink→过去）逼近玩家，而非直线卡在缺口边。
|
||||
|
||||
- [ ] **Step 3: 验证到范围选招攻击 + 暂停逼近**
|
||||

玩家进入某招 `rangeRadius`。预期：敌人**停下逼近**、播该招攻击；打完回逼近；若仍在范围且招就绪→再次选招（`WeightedRandom` 下多次交战招式有变化）。切 `attackSelectionMode=Priority` 复验：稳定优先高 `priority` 招。
|
||||
|
||||
- [ ] **Step 4: 验证脱战回退**
|
||||
|
||||
玩家跑出全部感知区。预期：敌人退出交战、回巡逻（Rest=Patrol）。
|
||||
|
||||
- [ ] **Step 5: 验证根因校验**
|
||||
|
||||
临时把某攻击招 `rangeRadius` 设 0，进 Play。预期：Console 出现 `[EnemyBase] 攻击招 '...' 的 rangeRadius<=0` 报错（不静默）。验证后改回。
|
||||
|
||||
- [ ] **Step 6: 记录结果**
|
||||
|
||||
把验收结论（通过/问题）记入 `Docs_Dev/Verification/`（沿用现有验证文档风格）。若全通过，本功能完成。

## 自检记录（写计划时）
|
||||
|
||||
- **Spec 覆盖**：§2 职责边界→Task 1/2/6/7；§4.1 SO 字段→Task 1；§4.2 InAttackRange→Task 2；§4.3 选择器→Task 3；§4.4 StatsSO→Task 1；§4.5 ICombatant→Task 4；§4.6 Pursue→Task 5；§4.7 状态机→Task 7；§5 边界/校验→Task 6/9；§6 测试→Task 3/7/9；§7 脚手架/Gizmo/自检→Task 8。全部有对应任务。
|
||||
- **类型一致性**：`EnemyAttackSelector(IEnumerable<IAttackCandidate>)`、`HasEligible(bool,bool)`、`Select(bool,bool,AttackSelectionMode)`、`ICombatant.HasEligibleAttack()/UseBestAttack()`、`IEnemyLocomotion.Pursue(Vector2)`、`EnemyBase.AttackSelector`、`Config.Engagement/ApproachState/AttackState` —— 各任务引用一致。
|
||||
- **顺序依赖**：Task 4（引用 `EnemyBase.AttackSelector`）需与 Task 6 连续实现、统一编译门（已在 Task 4 Step 2/5 注明）。
