NavMesh Extension (NavMesh Drawing & Portals)

Hi nogaskater,
the baking process takes all objects into account which are marked as (navigation) static in the layer settings. Please check that the terrain object is not on this layer for it to be excluded.

 

Thanks!

 

Hi!
I buy NavMesh, I have unity 5 in personnal edition, and... it don't work.
All is okay in exemple scene, but when i click on "Edit Mode" button and try to place a vertices in my scene, nothing appears...
So i try it on a new projet/new scene : same think.
:'(
Can you help me Baroni?

Thanks!
(sorry for my english ^^ )

 

Hi, thanks for contacting me.
Do you place vertices on a collider? It can only detect clicks on "hard surfaces", with colliders.

 

Oh... my bad.
I have a collider... on a plane... import to 3ds max...

Thank a lot for this very fast reply! It's perfect now on box with collider!

 

@Tomredfog You're welcome!

 

Seems like demo scene doesn't work in Unity 5...

 

It has been successfully tested against Unity 5.0. Which Unity version are you using and what does "doesn't work" mean?

 

5.0.2.f1

Ok, don't worry, I didn't noticed console saying "Navmesh agent format has changed, please rebake"

Once you rebake, everything works fine, thanks.

 

Hello Baroni.

I am really interested in the Portals Feature. However, I am having some trouble getting it to work.
1. I have used the Portal Manager to place one portal In my scene.
2. I have place to separate nav meshes on my scene. The first portal is on one navmesh and the second is on the other.

When I have the nav agent move to a waypoint located on the second navmesh the nav gets stuck at the edge of the first navmesh. Do the "portal nodes" need to have a Collider Component added to them or something?

thx.

 

Hi there,
no, colliders are not necessary. Do you use the AgentController script of the sample scene - which builds the path using PortalManager.GetPath - or how do you pass the path to the agent?

 

Thanks for quick reply. I guess I am probably not going about things in recommended way. I have done the following:

1. Add the NavAgent to my game character.
2. I added a simple script to the player (via add component, and select script component) that will have her move to a specified point:

void updateMoveToTarget(GameObject trgt) {

Debug.Log ("Selected Object is: " + trgt);
if (trgt != null) {
gameObject.GetComponent<NavMeshAgent> ().SetDestination (trgt.transform.position);
} else {
gameObject.GetComponent<NavMeshAgent> ().SetDestination (gameObject.transform.position);
}

}

3. Created my navmesh using your manager (very intuitive design btw) and baked it.

This got me to the point of having my character move around the screen towards whatever target is placed in the updateMoveToTarget() method.

Then I thought "oh that is neat so let's play with portals." Never got that going, but from your statement I think I need to review your sample code.

thx.

 

ok reviewed your AgentController code. Good example (sorry for not checking that first). I will implement that process, and let you know.

 

Hi Baroni.

I just wanted to followup with working portal example:

thx

 

@myibmaccount the video is set to private!

 

Oops. LOL. Just set it to public.

 

Hi Baroni,
I'm about to buy this great asset, but first I have to know, if it's possible to instantiate and use these nav meshes at runtime? If yes, will the transition between these generated meshes work well? Does offmesh link from unity work on these nav meshes?
Thanks in advance for your awnser, und viele Grüsse aus deinem Nachbarland Schweiz!

 

Hi @Bralgs, unfortunately not. If I may quote a question on the first page of this thread:

Grüsse zurück!

 

Can i set the navmeshes areas and cost?

 

Yes, this asset does not customize Unity's NavMesh settings so you can use them like before.

 

Hi Baroni,

I've just purchased this extension and I'm having a problem were vertices are being placed above the ground when I want them to be placed exactly on the ground. Would you know how to solve this problem and is there a tutorial on how to use this extension?

Thanks,

Mark

 

Hi @markskelton,

have you had a chance to look at the timelapse video on our Asset Store page yet? On the NavMesh Object component (where you enter and leave the edit mode) you can specify an Y offset value, or set it to zero. By default, vertices are placed on the collider you've clicked on + the additional height you've specified for the y offset. So make sure that your colliders are fitting the ground perfectly too.

 

Thanks for the quick response! That's fixed it now. A short video with a voice over on how to use the basic features of your plugin would be brilliant, but it's understandable if you don't have time to do this.

 

Hello Baroni,
Is there a way for the navagent not to stagger everytime i click somewhere to move. Right now if i click a forward direction the player starts walking, if i click a destination slightly ahead or same direction, the player slows down or staggers before going to the next destination. Can you tell me where should i update the code so it doesn't loose it's walk speed and just keeps walking?

 

Hi @Noeinz,

this is the default NavMeshAgent behavior, not something controlled by my code. Have you tried setting auto braking to false in the navmesh agent inspector?

 

so this uses the native navmesh builder

 

Yes.

 

Are you guys still supporting this product?
I tried to reach you on Facebook and Twitter but got no response.
Im having a real hard time making it do anything useful with a terrain shaped mesh.
Most of the time it will place random points in the air, and other times it just leaves huge gaps in the nav meshes.

 

@JohnRossitter Yes, I do - there was an update not too long ago. We don't have a public Facebook page/account, I wonder who you've tried to contact

Could you please send a small repro with the terrain via email so I can take a look (email is stated on our website and in the documentation PDF).

 

I just bought it 3 days ago, so unless your update was in the last 3 days, I think I have the latest version

 

@JohnRossitter Still, I would need a sample scene / repro / mesh to investigate the issue.

 

Well, I have 12 gigs of project, perhaps you can TeamView and look

 

With all due respect, I can't take a look at something and then do a fix afterwards without any chance to reproduce it again under the same conditions. You're an Asset Store publisher yourself, you know how this works. There has to be some effort put on both sides. Your mesh possibly isn't 12 gigs.

 

Wow, thats a bit harsh.

The issue is that the tool is selecting vertex locations that are not on my mesh, so to replicate the issue I would need to let you test it in the same environment that it is happening in.
As a publisher yourself, you should revel in the opportunity to have remote access to another development machine so you can see first hand what issues are happening as well as have the tools to diagnose and possibly fix said issues.

If you just dont want to help, thats cool Ill find another tool

 

I would like to help - as always. I'm here asking for a reliable way to reproduce your issue on my end after all. I just don't want to access your machine because it's (a) a time consuming task for both of us and (b) not something that seems to be easily fixed just by looking at it. I need a way to reproduce this so I can work on it. If you can't send me the mesh, how should I be able to fix it? I don't want to modify things in your project either.

 

It doesn't matter, Ill just make the nav mesh data in Maya.

 

hey there, just a couple of questions i have...

Regarding this package, is the option possible where you could bake different geometry to a specific NavMesh area? (e.g. land area: cost 3, underwater: cost 4) Also, could i use this tool to create mesh ontop of a terrain? (to set rivers or underwater places)

thanks

 

Hi @KIR99,

thanks for your interest!

- Yes, each mesh group you create is separate game object you can assign to different navmesh areas. In Unity 5.6, this can be done via the NavMeshModifier component attached on the mesh.
- Currently the mesh creation does not work well with terrains. I mean, you can create meshes on top of terrains, but they will still be flat and won't follow the surface shape closely. This would require something like a deformation feature, to bend the mesh to fit the terrain shape.

 

Greetings!

Please consider this as feedback to the developer and a little advice for people that stumble across the same problem as me.

Irecently bought this tool since manually drawing a NavMesh is a very cool thing to do. However, I found that deleting Vertices of the created mesh is rather bugged for me: Lets say I want to delete the vertex indicated by the arrow on "NavMesh1" which didn't connect due to a misclick by myself. I delete it and "NavMesh2" happens. This can be a real pain if you have a rather large NavMesh and you want to delete one single vertex - you have to create the mesh all over again or keep an unclean Mesh.

It took me a while, but I finally found out that creating triangles rather than rectangles is to way to go ("NavMesh3-5").
Maybe this could be somehow mentioned in the Quick Start Guide?

Except for that, now it works like a charm and I'm very glad I found this product.

 

Hi @Antragon and thanks for the screenshots! Although each quad is basically a triangle (or two, technically), the behavior you've described in NavMesh1-2 should definitely never happen. I'll try to reproduce that on my end, thanks again for the bug report!

 

I am working on generating procedural landscapes (terrains) with object spawning at runtime. Would this asset help me to dynamically create navmeshs on the terrain?

 

Hi @StevenPicard, please see this post for a related answer. Runtime NavMesh baking is supported by default using Unity's new navigation tools introduced for Unity 5.6 (but available on GitHub as a separate download). This asset let's you draw specific meshes / areas for use with Unity's navigation system, but it does not generate any NavMeshes itself.

 

Hello, I've run across a bug. If you click "New NavMesh" on NavMeshManager, then start drawing a few points (I used 6 verts to draw a concave shape) in the scene, then control click to add a new point on a sub mesh (only one vert), then turn off editing, there will sometimes be an exception. It doesn't always happen, but it appears to happen about 40% of the time.

I realize that's not the intended way to use the tool, but I did it by accident and had to delete and redraw the mesh to fix it.

First exception is:

Code (csharp):

1. Failed setting triangles. Some indices are referencing out of bounds vertices. IndexCount: 24, VertexCount: 0
2. UnityEngine.Mesh:set_triangles(Int32[])
3. NavMeshExtension.NavMeshObjectEditor:DeleteSelected(Boolean) (at Assets/NavMeshExtension/Scripts/Editor/NavMeshObjectEditor.cs:487)

6. NavMeshExtension.NavMeshObjectEditor:OnInspectorGUI() (at Assets/NavMeshExtension/Scripts/Editor/NavMeshObjectEditor.cs:90)
7. UnityEditor.DockArea:OnGUI()

All the following exceptions are:

Hi @SloppyDepot,

thanks for the report. If this is not critical to you, I will try to reproduce and fix this for the next update.

 

It's not critical, thanks for looking into it.

 

Hi!
I used navmesh extension for create path, but when I exported the game it see the path.
How can I do for do not see the path my game?

 

Hi, you can disable the Renderer component (in the inspector) on the NavMesh you've created.

 

thank you!
it is working

 

Am I right thats not possible to change a normal nav mesh build with the nav mehs system ?

 

Not sure what you mean by "normal nav mesh build" and "the nav mesh system"? What do you want to change and how?
