image 当您将Volume添加到关卡时,您会注意到RecastNavMesh-Default还添加了一个Actor。这个Actor具有我们可以用来可视化我们的NavMesh的不同元素的设置,我们还可以调整它的生成方式。 image 我们应该首先将 Agent Radius 和 Height 设置为 44.0 和 192.0 以匹配我们的角色。这将导致 NavMesh 正确识别我们游戏的所有可...
为了使用 NavMesh 进行 AI 导航,首先需要生成 NavMesh 数据。在 Unreal Engine 中,这可以通过以下步骤实现: 虚幻引擎中的基本寻路 | 虚幻引擎 5.4 文档 | Epic Developer Community (epicgames.com) 步骤: 打开场景后,在场景中放置一个 NavMeshBoundsVolume,覆盖你希望 AI 能够移动的区域。 按下P 键,你可以看...
注意:GetRandomPointInNavigableRadius节点使用了导航数据(称之为NavMesh)来判断一个点是否可达。在本例中,我已提前创建好了NavMesh。你可以通过在Viewport选中Show\Navigation观察NavMesh。 如果你想创建自己的NavMesh,请创建Nav Mesh Bounds Volume,缩放其大小为理想可达区域。 接下来,我们需要将位置数据存储到黑板里。
NavMeshBoundsVolumeを選択して、フロア全体をカバーするために[Details]パネルで[Scale]を X = 20, Y = 20, Z = 5 に設定します。Unreal Engine はデフォルトでナビゲーションバウンド内に自動的にナビゲーションを生成します。ナビ...
Generating the Navigation Mesh Generating a simple Navigation Mesh is pretty straightforward in Unreal. Let's look at how we can do it. From the Mode panel, in the Volume tab, you will be able to find the Nav Mesh Bounds Volume, as shown in the following screenshot: Drag it into the ...
Setting parameters for the Nav Mesh If you click on the Nav Mesh Bounds Volume, you will notice that there are no options for the generation of the Nav Mesh. In fact, some parameters are at the project level, while others are at the map level. Let's navigate to the World Outliner, ...
Fixed an issue where the navigation mesh was not generating correctly when the NavMeshBoundsVolume was placed perfectly flat on the floor surface. Added a safety check when loading a navigation mesh to check if code referencing an older version of the navigation mesh attempts to...

如果是一个空白场景,而不是这个demo中说的template “Blueprint Top Down”, 那么还是需要一个”Nav Mesh Bounds Volume”来框住整个角色的运动范围; 按照官网的说法:” The NavMesh in Unreal has a number of functions that work well with Behavior Trees, and while it may not be necessary depending on...
When I install a NavMeshBoundsVolume for the VR teleporting to work, I see the green shading indicating where I can move in VR. Of course, my typical exam room is full of stuff in it and the green shading does not flood into the room as a result of the objects and collisions associa...
