AI vehicles won't drive on Roads anymore
Closed, ResolvedPublic


Hi, just trying to make a tank (an AAF Kuma in this instance) drive along the main road from Feres to Selakano on Altis. I've tried every behaviour mode, at varied speeds, but the tank won't stick to the road. It zig-zags, goes off course, and does a whole manner of crazy stuff. This is also now happening with cars - I placed a Strider on a long stretch of highway and made it move to a waypoint a little farther on. It decided to zig-zag its way there! {F24748}

Place a tank on the main road from Feres to Selakano. Set speed to limited and set behaviour to safe. Add a waypoint further up the road. The tank will not follow the road in a smooth,logical manner.

I've uploaded a picture - you can still see the tank tracks - but I've added a yellow line to show the tank's path.

Ah - noticed it effects everything, cars included - guessing this might just be a devBranch, WIP thing!

I've noticed that on Dev Branch. AI pathfinding on roads has gone very strange.

I thought this was just happening to me on particular bit of road. I've got some APCs driving up a steep hill, and they keep swerving off course and rolling off the edge. I had to put down concrete barriers to stop them doing it, but then it got worse after the recent change relating to AI walking through editor-placed objects. After that, the APCs started trying to avoid the barriers and ended up going up the hill on the other side of the road.

Yes, it seems AI vehicle movement on roads is er, not right. Any idea if this is just Dev Branch tweaking?

By the way BIS, this bug totally messes up the convoy behaviour in "Moral Fiber" from the WIN episode.

As well as 'Supply Network' - actually makes the mission unplayable! (Switching to Stable, I'm sure it'll be fixed soon!)

Yeah, as Armadillo says, I'm sure it'll get a quick fix!

Thank you for the report!

Was introduced by recent AI fixes/optimizations. We're on it!

Lol, knew you guys would be all over it! Thanks for the update!
