AI Driving - Feedback topic

Recommended Posts

And inbefore you go with "its broken", yes, there was an issue with Physx vehicles, fix is incoming. I will unlock the thread once the fix safely lands on dev-branch the fix is imminent and I go to watch some football.

Well done, I placed a Hunter on Tanoa, placed a waypoint north of Tanoa, and just let the AI drive. Best taxi drive I've ever had - video will follow soon for those not on dev branch e.g ~0.14% of all players

 

Two things I noticed during the drive:

 

- AI likes to cut curves -> This sometimes leads to a collision with close to the street placed objects

- They sometimes enter crossroads to fast, especially when the road went downhill before and the speed was very high (150kph)

 

A question about configuration:

 

How does the driver know the dimensions of the vehicle. In the past, the driver would try to avoid objects which were not even in the path of the vehicle, just very close, which would then lead to very strange accidents.

 

 

 

 

Again, well done, enjoy your weekend ;)

First attempt at the new driving AI.

 

SIngle Hunter GMG:

It reached its destination and only hit one wall while doing so.. sometimes the AI goes offroad for now apparent reason, and in general they drive slower than before, but that's fine, they do hit the metal once they are on long straight paved roads.

 

Convoy:

Consisting of:

Hunter GMG - HEMMT Medical - HEMMT Transport - Hunter HMG

 

I have to say unfortunately this turned out to be a nightmare. The vehicles would constantly bump into each other, even pushing each other off road. At one point the two HEMMT were so colied up that I had to use Zeus to get the two apart (I'm aware how dirty that sounds). Again, AI would randomly swerve off road, especially the faster Hunter in the back, but even the lead hunter would do that from time to time (right in time to kill a telephone mast). Vehicles would not keep formation.
Settings was "Relax" and "Do not engage", normal speed.

I'll keep you posted.

Yes, this needs tweaking, please try Safe, it will make them use Convoy algorithm.

Test mission included

 

Setting them to safe helps. However, they still often bump into each other. They definitely need to watch their speed

Tried to get a convoy going for 15 minutes, no luck, the issues already start with how one has to set up the convoy.

 

From the editor there is no way to tell which vehicle drives at what position in the convoy, that creates alot of confusion, causing the AI to get in order/line first -> bumping into everything, except there is enough space -> Tanoa Airport

 

I know this is not really related to your pathfinding improvements, but maybe you can pass this down to one of the Eden devs.

Great news that this is being looked!!!

I will test with a ravage convoy script I have tonight...

Excited for these changes...

Loving BI right now :)

This is really exciting! Thank you!

The initial post seems to indicate it works with all "cars" by default, but then says it needs to be configured for every "car."

I know this is a test for vanilla as these features are new. But will any and every car, including modded (assuming they use conventional vehicle making practices) inherit the new behavior? Or just vanilla for now?

No luck with SAFE, here's a video. Sorry about the shitty audio, I had my mic open and it recorded the vibrations of the computer it was lying on

Already looks a million times better than on dev. Really hope there is still room for tweaks.

By default all vehicles inheriting from base class Car has enabled component with settings as I've pasted in first post. This means every car which does not change parameters, will have it working, vanilla or not.

I'm not getting much improvement at my end.

Using Convoy and Safe mode they still seem to exhibit the same issues as previously seen, ramming and driving off road.

Rather than use brakes they seem to want  to swerve left and right until they eventually hit something.

 

In single vehicle mode they do tend to get there as long as there are no oncoming or parked vehicles to avoid, when they do encounter such an object they go off road and it's just luck it they don't hit anything or get stuck.

 

I also tried using forcespeed but this also has an odd behavior, at lower speeds it seems  ok 15kph  but at  40kph  the vehicle starts to swerve left and right as if they're warming up their tyres for a race.

This can get so bad they will over do it and  hit road side objects.

Forcespeed doesn't seem to force that exact speed, instead the driver uses the closest of the three possible speeds - slow/normal/turbo.

No, I assumed the given value was in km/h, but it's m/s. My bad.

 

The swerving looks fine to me. My chauffeur was just slaloming the road marker posts:

Yeah, that convoy AI is still a nightmare :(

The only 2 solutions I found to make a proper convoy are:

 

-either use unitcapture/unitplay

-or make each and every vehicle independant but with limitspeed. you place each vehicle one after another, not grouped and put the same limitspeed to each of them and it should work (more or less).

Are you sure about forcespeed, mine try and drive at whatever speed it's set to 1kmp they are walking pace at 100kmp they are going mental hitting every thing they can.

Can't do video as my connection it too slow and takes forever.

Drivers seem to try to take shortcuts even when it makes no sense.  Like it'll take a slight mud road that shortcuts around a curve, driving through a village instead of around it on the road they were already on.  In this case it ended up stopping the vehicle when the driver of an SUV tried to drive northeast up a hill to take a foot path to La Rochelle instead of staying on the major road and driving NW around the lumberyard:

Those 'mud shortcuts' are classed as roads.

Looks pretty realistic. The same thing happens IRL when you're relying too much on GPS. :) Indeed, this problem stems from the exact same root - no differentiation between road types.

 

Also, would that be possible to make a "keep to the rules of the road" option for AI? It'd try to stay as far to the right side of the road as possible, automatically clamp speed according to roadsigns (might need additional work map-side), would never go off the road and would take sharp corners very carefully. Basically, making it simulate a civilian driver, as opposed to a soldier whose only concern is getting from A to B in minimum time.

Just need a "dont leave the road ever" function, and also some test of surface type to prevent the driver picking roads on wrong surface types.

Had a test... up thru La Rochelle...

 

It is much better... I immediately noticed the AI braking before the corner where it seemed like the old way they would get way too deep into the corner before braking.

 

Only hit one roadsign merging back on to the asphalt but certainly working to getting the big Red P on the back of the AIs cars removed LOL.

 

I also noticed if you ordered the AI to disembark and re embark that i could re order a move point but  once the ai reachs that point it breaks.

Could then do again to get AI moving to assigned location via mapclick

 

looking very promising... not to try some ambient cars and AI

I am still getting AI refusing to drive sometimes, on the current 1.63 build.

Same here.
