From 4ecf949d830b72d1183ad02c30914b04d596afef Mon Sep 17 00:00:00 2001 From: Joywayer Date: Thu, 23 Jul 2026 10:10:35 +0800 Subject: [PATCH] =?UTF-8?q?fix(enemy):=20=E7=9B=AE=E6=A0=87=E7=82=B9?= =?UTF-8?q?=E5=90=B8=E9=99=84=E6=94=B9=E7=94=A8=E8=B7=9D=E7=A6=BB=E8=87=AA?= =?UTF-8?q?=E9=80=82=E5=BA=94=E6=90=9C=E7=B4=A2,=E4=BF=AE=E5=A4=8D?= =?UTF-8?q?=E7=A8=8D=E7=A6=BB=E5=9C=B0=E8=B7=AF=E7=82=B9=E5=90=B8=E9=99=84?= =?UTF-8?q?=E5=A4=B1=E8=B4=A5?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 之前 TryGetStandablePointNear 用固定 2m 搜索半径(实为 ±1m AABB)+ agent 过滤映射, 导致摆放在离地面 >1m 的路点(如 wp y=3.16 而地面段 y=2.00)映射失败、误报"超出搜索半径"。 改为与 PB2d 自身 UpdatePath 映射目标完全一致:搜索距离=agent 到目标距离(+0.1), 用不带 agent 过滤的 TryMapPoint(就近段几何映射,可达性交给 allowCloseEnoughPath 寻路阶段)。 只要图上有段就一定吸附得到最近点。移除 EnemyNavAgent._goalMapSearchRadius 固定半径字段。 Play 实测:两个路点 ResolveStandablePoint 均 ok=True((-20.90,3.16)->(-20.90,2.00)), CanReach=True,敌人实际走到 x=-20.75(目标 -20.90)后停,无 EnemyLocomotion 报警。 Co-Authored-By: Claude Opus 4.8 (1M context) --- .../PathBerserker2d/NavAgent/NavAgent.cs | 22 +++++++++++-------- .../Enemies/Navigation/EnemyNavAgent.cs | 8 ++----- 2 files changed, 15 insertions(+), 15 deletions(-) diff --git a/Assets/PathBerserker2d/Scripts/PathBerserker2d/NavAgent/NavAgent.cs b/Assets/PathBerserker2d/Scripts/PathBerserker2d/NavAgent/NavAgent.cs index 1a259062..9c3e6b09 100644 --- a/Assets/PathBerserker2d/Scripts/PathBerserker2d/NavAgent/NavAgent.cs +++ b/Assets/PathBerserker2d/Scripts/PathBerserker2d/NavAgent/NavAgent.cs @@ -620,20 +620,24 @@ namespace PathBerserker2d return PathTo(goal); } - // [项目新增] 目标点吸附：把任意世界点映射到最近的、agent 容身得下的可行走段上，再按 endMargin - // 从段两端内缩，得到"身体真正站得住"的世界点(避免落在角色宽度站不住的崖沿被移动层夹停)。 - // 与 SetRandomDestinationOnCurrentSegment 同源：endMargin 传 agent 半宽 + 落崖检测余量。 - // 段短于 2*endMargin → 退化到中点。searchRadius 内映射不到任何段(目标离导航面太远)时返回 false。 + // [项目新增] 目标点吸附：把任意世界点映射到最近的可行走段，再按 endMargin 从段两端内缩， + // 得到"身体真正站得住"的世界点(避免落在角色宽度站不住的崖沿被移动层夹停)。 + // 与 SetRandomDestinationOnCurrentSegment 同源：endMargin 传 agent 半宽 + 落崖检测余量。段短于 + // 2*endMargin → 退化到中点。映射方式与 PB2d 自身 UpdatePath 映射目标一致(见 UpdatePath)： + // 搜索距离 = agent 到目标的距离(+余量)、用不带 agent 过滤的 TryMapPoint(就近段几何映射,可达性交给 + // allowCloseEnoughPath 的寻路阶段),故只要图上有段就一定能吸附——不会像固定小半径那样漏掉稍离地的点。 /// - /// Maps to the nearest walkable segment the agent fits on, + /// Maps to the NEAREST walkable segment (same robustness as + /// PB2d's own goal mapping in UpdatePath — search distance scales with agent→target distance), /// then insets by from BOTH segment ends so the returned point is /// one a bodied agent can actually stand on (not clamped at a ledge).
