The edge vertices can be adjusted as in Chapter 3.4.
The mesh needn’t be accurate this time. It can be extendable later as in Chapter 3.3. The mesh needn’t be completed at one time. Click the stop drawing button or type Esc key to stop and save. Click the other side of the area’s edge, a new triangle is got. Click the next point on one side of the area’s edge, a new line is got. Along the edge of the area, click on the scene view, a point is generated in the scene. Other than that, you don’t need to care about the storage too much, it has no impact on the scene data.īy clicking the Markermesh Creation button, as shown above, you will start to mark a new area. And it is best to manage them with your revision control system(svn/git/…). With another button named Import From Mesh Object…, a normal mesh can be imported from the asset or the scene. Still, these jobs can be done manually via the 2 buttons. Automatically, the data is loaded when the window is shown and is saved when you complete the editing jobs or the scene is saved. In the NavimeshMarker Editor Window, there are 2 buttons named Reload From Files and Save To Files. And it also means next time the scene is loaded in the editor, you have to open the NavimeshMarker Editor Window to show the markermesh in the Scene Window. It means none of them will be included in the packed App. The gameobject EditorOnly-WontSaved-MarkerMeshManager and the sub-objects are for editor only and won’t be saved in the scene. The markermesh is loaded as sub-game objects with a MeshRenderer component attached to each of them, so the markermesh can be shown in the scene. Then, a gameobject named EditorOnly-WontSaved-MarkerMeshManager is added to the scene. When a scene is loaded, nothing is changed to the scene in the hierarchy until you open the NavimeshMarker Editor Window via Window -> NavimeshMarkerWindow. 
For short, these mesh data are named markermesh below. markermesh.Īnd the mesh files are named sequentially and stored in JSON format. Connecting two edge points to form a new triangle.Īs described above, the meshes data is saved in the same directory as the Unity scene file(*.unity), with the same name as the scene name and the fixed postfix.In this workflow, you must pack the runtime data into the release package.Īs an editor tool, an editor window is made to manage the meshes’ data. The exporting and the runtime source are available via this link(I only add new files and nothing changes are made to the original source, so it is easy to rebase.). And it can be used anywhere as it is written in C++.

An example is provided to show how to use these data in Unity. Then the data will be saved in JSON format and transferred to the Detour format.

The meshes intersection and the union calculation will be performed(The source code of this part is in secret.) during the exportation and the edge vertices are kept. Or you can also export the navmesh without the baking workflow. And it needn’t be packed into the game, which will save the memory at runtime. Instead, they are saved as files in a directory besides the scene file.
And the meshes won’t be saved with the scene. And the navmesh data, instead of the meshes, is utilized at runtime eventually.
provide a bake-free runtime navmesh data with Open Detour format.Īfter the meshes are generated, you can follow the old workflow to bake it to the navmesh data in the Unity Navigation Panel. Then a smarter navigation path will be generated at the runtime and leads to a better AI interaction with different terrains. With the meshes, it is easy to mark a certain area as a specific Navigation Area, which can have different navigation costs. The user can easily generate and edit meshes sticking to the ground. NavimeshMarker is a Unity Editor tool that aims to The re-baking workflow makes the server data different from the client’s, which brings in bugs. I have the open format runtime data so that I don’t have to re-bake it for my server. If I want to mark certain areas, my jobs would probably depend on the artist. I have to select/un-select the existing mesh made by the artist, which is easy to make mistakes. I can edit the navmesh freely within Unity. And the longer I work with it, the stronger feelings I have would be if 
As the project turns large, the meshes can be too complex to match a navigation area. It is useful to bake meshes into a NavMesh file in Unity.
