Nav Mesh Jump Link Automatic

[MarcAndreG]

Hi,

I’m trying to create an automatic way to create nav link.

My current code sits at the very end of void FRecastTileGenerator::GatherGeometry, gets all the polys, then get all the vertices, and then do some simple checks to validate if they are a valid pair.

It kind of work.

If I just re-trigger the nav mesh generation, everything is perfect, links are created and in the proper place.
But if I move an object, it seems that I use the old nav mesh to generate the links, so if I do a very small move, it looks like it works but everything has a “small” offset. And if I make a big move, no link are created since there was no vertices there before.

When I noticed that I tried creating the link inside FRecastTileGenerator::GenerateNavigationData but with no success.

Is there a better place / better way to do what I need to do where I would have the full data of the full and newly generated nav mesh ?

Thanks

I’m interested! would you mind share some details?

Not quite the same thing, but I made my own version of this and wanted to share ( after visiting this and many other threads, searching how to do this ).

I ended up with a manual button that needs to be pressed in the editor, which kind of sucks ( will continue to hunt for how to best hook this in for auto-generation ), but it generates the nav mesh links, and my world content author is very excited to not have to do them manually (we have fairly large worlds, which can have ~1000-2000 links generated in it )
