Nextbot attempts to avoid small inclines as if it were marked avoid, but isn't.

[DarkAura]

So I made a nextbot NPC, and the picture below represents what happens when they try to walk over a small gap, they typically walk on the white line, stop, walk along it, rarely cross, and when they do it is at the flat part, so it is probably something to do with the splice navmesh.

It is quite odd, I have the code just in case it has to do with RunBehavoir, otherwise, my guess is they are scared of the spliced navmesh.

Thanks if you can help.

See those cyan lines that connect the areas in the navmesh? Those indicate "one way" connections. To make them to way, you need to tell next bots that they can go from one area to the other AND back. Highlight the other area with your cursor, `nav_select`, mouse over the current area, `nav_connect`, you should see the cyan line go blue. When you do, `nav_save`. I've been meaning to write a tutorial on navmeshes since there's so little documentation. I just can't seem to find the time...

[DarkAura]

Cyan is two way, dark blue is one way, I'll try disconnecting and reconnecting them anyway tho.

[Apickx]

You're right, my bad. Can you turn the path drawing on so we can see where they think they should go?
self:MoveToPos( pos, { tolerance = (math.random(25,50)), maxage = math.random(500, 1000), lookahead = 1000, draw = true})

[DarkAura]

I will later, but for now, the draw path literally just either stops on the line and then goes along it, or it just stops short of it, then turns around.
