hello
(i guess this one is for normen)
i was busy porting the game programing gems 1 navmesh code,
but as i was strugling to make it work (c++ -> java is a bloody pain in the ass)
i nothiced this code from normen 667 : https://code.google.com/p/jmonkeyplatform-contributions/source/browse/trunk/jme3-artificial-intelligence/AI/src/?r=674#src%2Fcom%2Fjme3%2Fai%2Fnavmesh
i was wondering if this code was ported(finished) and working ?
is there some test case somewhere ?
thx
It’s a plugin that you can download and use in the SDK.

you mean the navmesh generator ?
i dont get it, correct me if i am wrong, but…
i already used the navmesh stuff from monkey zone wich uses recast or its java (jni) equivalent if i remember well
but from the source of normen code i see it is a port from gem programming ai chapter 06
wich seems to be simpler and also what i was planing to do, but already done
Nope I’m talking the “JME3 AI Library” plugin

hmmm, cant find it in the ide (plugins window)
btw is norman on holiday ?

thx, but i cant download it on the page, i am not familiar to github site
how do i proceed ? do i have to sign up ?
Is there not even the last nightly and contrib build that worked on the old update server @sbook?
@curtisnewton: Normally it should be in the plugin list as nehon indicated. But the release of jME 3.0 isn’t that far, I guess the delay is now mainly due to me being busy all the time privately, sry

uber coooooool 
(even when nightly checked, the ai library dont show up)

GitHub is just a place for hosting git repositories. The concept is similar to that of Subversion and other version control systems. If you look on the right side of the jmonkeyengine-contributions project page, there are instructions on how to clone the repository as well as a link for downloading a zip snapshot.

Yup, it built a few days ago… I’ve put it on dropbox: Dropbox - Error - Simplify your life
I use the NavMesh in my game, but during the tests I noticed a few strange behaviours. I didn’t take the time to go into them yet.
But for exemple, sometimes it takes a longer path. And you can’t set a minimum width for your entity. You have to do this with the MeshPath which can become a problem if you have entities of different widths.
There’s also a property to make the turns from a distance from the corners, but it doesn’t check if it goes outbounds or anything.
Besides these little limitations, it works. 
Is the GIT version different from the SVN one ?

yep, i already cloned git stuffs, but on the page there is no link to the repository, nor the usual .ZIP button
anyway i got the jar, but is there come testcase, how to use it ? perhaps monkeyzone ? donno if it uses the same lib
i can already use my own code wich is compatible 
[java]
NavMesh navMesh= new NavMesh();
navMesh.addCell(new Vector3f(1,0,1),
new Vector3f(1,0,0),
new Vector3f(0,0,0));
navMesh.addCell(new Vector3f(0,0,1),
new Vector3f(1,0,1),
new Vector3f(0,0,0));
navMesh.linkCells();
[/java]
but how do i proceed to indicate the start/end point
and build a navigation path, …
ok here is the (easy) code for those who want to get a hand on this
[java]
NavMesh navMesh= new NavMesh();
navMesh.addCell(new Vector3f(1,0,1),
new Vector3f(1,0,0),
new Vector3f(0,0,0));
navMesh.addCell(new Vector3f(0,0,1),
new Vector3f(1,0,1),
new Vector3f(0,0,0));
navMesh.linkCells();
NavMeshPathfinder navMeshPathFinder = new NavMeshPathfinder(navMesh);
navMeshPathFinder.setPosition(new Vector3f(0.1f, 0.0f, 0.05f));
DebugInfo debugInfos = new DebugInfo();
if(navMeshPathFinder.computePath(new Vector3f(0.85f, 0.0f, 0.9f),debugInfos))
{
Path path = navMeshPathFinder.getPath();
if(path.getWaypoints().size()>0)
{
Iterator<Waypoint> it = path.getWaypoints().iterator();
while(it.hasNext())
{
Waypoint wp=it.next();
…
}
}
}
[/java]

I meant at the old location on the jmonkeyengine.com server.

Yes, it was in Jenkins but the artifacts of the projects aren’t publicly viewable or else I would’ve just put up a link to build.jmonkeyengine.org

No, I mean in the original location, where the current SDK looks for them. jmonkeyengine.com/updates/…

hello normen, can you have look a this : http://hub.jmonkeyengine.org/forum/topic/ai-navmesh-random-distribution/
when you got some time
i created a new thread cos it is another question about that very code
thx
