AI Driving Control

version 2.6.7

 

Description:

• Gives more control to AI drivers.
• Script uses nearEntities to find vehicles/men, calculates relative angles to nearest one and applies forceSpeed depending on situation.
• Use "STEALTH" behaviour to temporarily bypass the script.

 

Features:

• AI will brake and speed up for vehicles ahead.
• AI gives way to vehicles approaching from the right.
• Pedestrians have priority over vehicles.
• Pedestrians are overtaken or followed if directly in front of vehicle.
• Works on and offroad.
• Have less (not avoid) crashes.
• Engines turn off on idle if at final waypoint.
• Vehicles on "STEALTH" behaviour bypass code until behaviour changes (setBehaviour, etc.).
• Bypass script entirely on a vehicle's init with "this setVariable ["NOAIDRIVINGCONTROL", true, true]".
• For a convoy use "<object> limitSpeed <km/h>" on lead vehicle.
• Gates ("Land_BarGate_F", "Land_BarGate_01_open_F" and "Land_RoadBarrier_01_F") are detected when closed. Note: place gates BEFORE AI driver gets in vehicle/spawn/zeus/etc. i.e. not scanned in realtime. As a bonus, gates are made indestructible (by tanks as well unfortunately).
• Addon and script version.

 

Download:

• Google Drive

 

Usage:

• Works with placed and spawned vehicles, single player and dedicated server.
• Clients with AI drivers must be running the addon.
• For Zeus, the player being Zeus must be running the addon.
• Script version runs once on mission initialization and needs to remoteExec for each new spawn (except Zeus). Follow INSTALLATION.txt.
• Hold movement keys for (up to) 3 seconds if your vehicle's fuel was removed and you're the commander.

• Variables (vehicle's init field only):
  • Defines "bounding box" width, per vehicle, which detects men around and stops the vehicle. Where 1 = vehicle's width; 1.5 = default; 2 = default for tanks. Smaller values improve overtaking men but run them over more often, higher values will be safer but will halt more often. Higher than default should not be necessary:
    • this setVariable ["AIDCBBOXWIDTHCOEF", <coefficient>];
  • Defines "bounding box" length, per vehicle, which detects men around and stops the vehicle. Where 1 = vehicle's length; 1.5 = default:
    • this setVariable ["AIDCBBOXLENGTHCOEF", <coefficient>];
  • Defines setConvoySeparation for each vehicle on AI led groups only. AIDC overwrites that command by default so if it is to be used it must be defined here:
    • this setVariable ["AIDCCONVOYSEPARATION", <distance>];
  • Disable workaround of removing fuel of tanks when nearby infantry:
    • this setVariable ["AIDCNOFUELREMOVE", true];

 

Notes:

• Any forceSpeed command (on affected land vehicles) will be overwritten by the script.
• Does not cause dependency on missions.

 

Known issues:

• When confronted with large groups of pedestrians, vehicles occasionally  stall (with accelerated time only probably).
• Quadbikes are not detected by other vehicles on road (@BI: they always report "isOnRoad false"). Are detected offroad.
• Does not work on ALiVE vehicles.
• Incompatible with TPW SANITY (uses forceSpeed as well).

This is fantastic RCA3 !

 

Thank you very much for sharing !

What makes it incompatible with ALiVE?

Good question.

I tried running Alive and see if vehicles picked up the script, and they did, but they would close it almost immediately.

If you know how to run init vehicle code particularly on Alive vehicles or you know how Alive vehicles can run permanent while{alive}do{} loops, please let me know. Thank you.

 

Edit:

Changed "incompatible" to "Does not work on ALiVE vehicles." since you may still use your own vehicles.

Edited May 25, 2019 by RCA3
Changed Known Issues ALiVE note

[badanov 116]

This seems to be working very well.  I run several repeatable SP games, more than half involving road marches of BTRs and T-72s, and I can see a definitive improvement in road march behavior.  The AI also moves itself, so it will be interesting to see if all AI controlled enemy QRFs arrive safely to  the area of operation.

 

Well done.

             Fixed: Maintain speed of front.

 

I had to change the addon name because I believe people were coming here looking for something else.

I think you mean all the AI combat enhancement mods/addons;  I believe you'll have no problem using them together.

Interested in trying this but the readme states that there is an issue with tanks? Could you please elaborate?

"Something is wrong with tanks: ~10 tanks overloads the script, ~5 seems fine. "

 

Try it out, if it overloads (drastic FPS drop) reduce number of tanks.

Can't tell you exactly why this happens. I know it doesn't happen with other vehicles, APC's, etc.

Thought about it and realized it would be better (humanitarian convoys, etc). Sorry for the constant updating. This should be the last one unless something unforeseen comes up.

OMFG RCA3 ... you have done something that even BIS cannot do ... SORTED AI DRIVING !  What kind of friggen magic is this ?  I watched as trucks FAILED to run over friendlies, FAILED to crash into objects, FAILED to crash into walls ..... this is not the BIS way 🙂

 

For the love of all things sacred .. please keep working on this!

I know you're joking but Bohemia did improve on AI driving back in 2016ish swerving off things and are still improving as of last week.

Thanks, I'll do my best although this is pretty much at the peak of my capabilities.

@arma131

"Something is wrong with tanks: ~10 tanks overloads the script, ~5 seems fine."

 

I'm not so sure about this one anymore. Last testing wasn't as bad as before and I think it could have to do with my PC to begin with.

 

If someone could confirm or deny this issue would be awesome.

 

Here's a test mission with 10 tanks:

https://drive.google.com/open?id=1iR9Fv7Ff9RCUTG4IO_iYw-cCja8c38-c

[kremator 1065]

Testing now.

 

EDIT:  Not seeing any problems so far.

 

EDIT2:  A proper test would be 5 tanks approaching another 5 tanks.   Just added 5 more tanks into the mix, going to opposite way.  Mod handled it pretty well..... unforunately bloody stupid Physx ended with some tanks in the air or on their sides!

[RCA3 593]

@kremator

Thanks bro!

I'll strike that issue now.

 

Cheers!

[kremator 1065]

Is there anything you can do to fix the 'crash, interminably long pause, reverse in the wrong direction, recrash, anothre long pause, reverse in EXACTLY the same way as before, crash ...... etc' ?  I suppose I'm asking if there is a way to detect vehicle crashes.

 

Checked the mod on a dedi server (not fully optimised) and it does improve things .. but needs a little more tweaking I guess

Ok, what's not fully optimized, the addon or the server? Where do you see tweaking being needed?

 

As for crashie... I ain't even touching that. All I do is apply brakes and restore speed if there's someone/thing ahead or not. The long pause can be the script preventing move, or the game itself finding new paths. One note though: scans are all made from the front (hood) of the vehicle, so anything behind that isn't detected (e.g. like reversing on top of a man).

 

I'm guessing you're getting those results on the Altis test or somewhere where the road isn't very wide. As a rule of thumb give vehicles as much space as you can. Account for the vehicle types you're using and a realistic path for them.

 

Edit:

I did try and change timeout values with AICarSteeringComponent from https://forums.bohemia.net/forums/topic/191515-ai-driving-feedback-topic but without success. Maybe someone can build a patch with better values to complement my addon (specifically longer timeouts I find would be useful).

[dr@gon 118]

Someone needs to write a pedestrian script where after the first person gets run over by a giant military truck the rest get the heck off the road. I understand the frustration of your own infantry getting run over by your own vehicles when in column but when civilians stroll down the road and refuse to get out of the way of traffic even after someone has been killed is ridiculous.

There surely must be a way to check if people are walking/running towards a moving vehicle and redirect them a few metres away from that danger (apart from then loading etc)?
