From a4b9729de70b0f21a455101bc0493d1683125f1f Mon Sep 17 00:00:00 2001 From: Joywayer Date: Fri, 10 Jul 2026 15:12:28 +0800 Subject: [PATCH] =?UTF-8?q?@=20fix(enemy):=20=E5=B7=A1=E9=80=BB=E8=BE=B9?= =?UTF-8?q?=E7=BC=98=E4=B8=8D=E8=B6=8A=E7=95=8C=20+=20=E5=8D=A1=E6=AD=BB?= =?UTF-8?q?=E5=85=9C=E5=BA=95=20+=20Locomotion=20=E6=83=B0=E6=80=A7?= =?UTF-8?q?=E5=8F=91=E7=8E=B0?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - WouldBlockAhead(EnemyMovement)：按请求方向从碰撞体前缘(bounds.max/min.x) 即时射线判墙/悬崖，天然考虑碰撞体宽度；MoveHorizontal 据此夹紧前进，保证 "碰撞体边缘停在地形边缘、不越界"。移动层夹紧与 Pace 翻向共用同一判定， 避免"夹停却不掉头"。nav 走 MoveWithSpeed 不受影响。 - Pace 加窗口净位移卡死兜底：撞上未挂检测层的墙/卡角(含贴墙微抖)也能翻向， 用净位移而非逐帧差以免微抖重置计数。 - EnemyBase.Locomotion 改惰性发现：关域重载下 Awake 设的实例字段可能残留 为 null，首次访问按需补发现，编辑器/构建都不为空(此前致入口态偶发 NRE)。 PlayMode(跨调用取样，避免 Thread.Sleep 冻结主线程)验证：Pace 来回踱步、 遇边缘/墙掉头、碰撞体不越界。 Co-Authored-By: Claude Opus 4.8 (1M context) @ --- Assets/_Game/Scripts/Enemies/EnemyBase.cs | 4 ++- Assets/_Game/Scripts/Enemies/EnemyMovement.cs | 33 ++++++++++++++++++- .../Enemies/Navigation/EnemyLocomotion.cs | 27 ++++++++++++--- 3 files changed, 57 insertions(+), 7 deletions(-) diff --git a/Assets/_Game/Scripts/Enemies/EnemyBase.cs b/Assets/_Game/Scripts/Enemies/EnemyBase.cs index f0f84fcb..8bfae856 100644 --- a/Assets/_Game/Scripts/Enemies/EnemyBase.cs +++ b/Assets/_Game/Scripts/Enemies/EnemyBase.cs @@ -209,7 +209,9 @@ namespace BaseGames.Enemies // BD 任务访问接口（公共只读属性）──────────────────────────────── public IPathAgent Nav => _nav; - public IEnemyLocomotion Locomotion => _locomotion; + // 惰性发现兜底：关域重载后 Awake 设的实例字段可能残留为 null（编辑器快速迭代）， + // 首次访问时按需补发现，保证编辑器与构建下都不为空。 + public IEnemyLocomotion Locomotion => _locomotion ??
