release vAiDriving Multiplayer Script [v13 - updated 05/26/2020]

[LSValmont 789]

vAiDriving Multiplayer Script by Valmont RELEASED!

 

Improved Ai Driving and Civilian Pedestrian Simulation will now also increase your FPS rather than decrease it!

(Three for the price of one, order NOW!) (promotion ends when Arma 4 releases or we run out of stock!)

EDIT: -SOLD OUT-

 

Inspired by (And adapted from) the work of the Ai Driving master @RCA3  !

 

REQUIRES CBA_A3 !

 

vAiDrive Main Features:

1) Greatly reduces the chances of Ai Driven Vehicles colliding with objects, vehicles and other units.
2) Greatly improved the chances of Ai Driven Vehicles evading other vehicles and units.
3) Since version 13 the script is able to handle the waypoints and movement of both vehicles and pedestrians and therefore it no longer needs manual waypoints setup by the mission maker.

All that is required now is the placement of civilian vehicles and units on the scenario and the script does the rest.
4) By giving vehicles the optimal amount of waypoints, waypoint distance, timeout and position while also giving pedestrians custom routines that mimic real urban movement patterns the immersion of any mission using civilians is greatly increased.
5) Has the option to cache far away units and vehicles being handled by the script.
6) Due to its many optimizations, instead of having a toll on server performance this script actually INCREASES the performance (FPS) on the server!

 

Extra Features:

1) Ai units in the way of vehicles will move away from the streets and into buildings.
2) Option for Handled vehicles to open closed bargates automatically.
3) Option to add random uniforms and gear to civilian pedestrians automatically.
4) Ai vehicle Drivers will occasionally use their horns when a obstacle is in front.
5) Ai Drivers are optimized for driving! And if their vehicle run out of fuel then they exit the vehicle and the script stops (liberating resources).
6) The script uses a combination of scheduled and unscheduled Environments to achieve that virtual CERO impact on performance.

OBS: Since version 13 it is nearly impossible to have fatalities of any kind due to bad Ai Driving with vAiDriving enabled (for the CIVILIAN SIDE).

 

CHANGELOG:

Spoiler

version 13 "Automatic Vehicle Waypoints!" Release Highlights:

 

- vAiDrive now has the option handle the waypoints of vehicles automatically so that players and mission makers do not have to set up each vehicle and each waypoint individually nor have other vehicle movement scripts running enabled.(vAiDriving_handleVehWaypoints=true).
- vAiDrive now has the option to automatically cache vehicles and units to preserve resources when players are far away.  (vAiDriving_handleVehCache=true)
- It is now possible to set the vehicles handled by vAiDrive to never run out of fuel. (vAiDriving_vehUnlimitedFuel=true)
- vAiDrive can now also randomize the look of pedestrians automatically. (vAiDriving_dressPedestrians=true)
- All vAiDrive settings are now set by editing  the "vAiDrivingCONFIG.sqf" instead of the main fnc file.
- Fixed Ai civilians not looking at nearby pedestrians when "talking" to them.
- Fixed Bargates sometimes not being handled correctly.

 

version 12 "Handle Civilians" Release Highlights:

- Added the game changer vAiDriving_handlePedestrians param. If set to true the script will automatically optimize all civilians on the mission, turning them into
performance friendly agents that roam the map smartly,  going into buildings, "talking" to other civies and avoiding walking on the middle of roads for long periods.
- vAiDriving_handlePedestrians increases the server FPS even further than before! WAY WAY MORE!

- Further optimization and tweaking not worth detailing.
- After version 12 update the number of civilian casualties due to bad Ai Driving is virtually CERO.
DISCLOSURE: No pedestrians were harmed during the development of this script version. (FINALLY!)

 

 

How it works:

Spoiler

 

It is a very simple script but sometimes simple is enough for most specially if performance is key on the server.

The script runs on each Ai driver and periodically checking nearObjects (for units and vehicles) and lineIntersectsWith (for objects and structures).

If an "OBSTACLE" is detected then the Ai Driver hits the "brakes" rather harshly but it should in most cases diminish deadly collisions.

What makes this script so efficient is that it only runs if the FPS is above 15 and the speed of the vehicle is greater than 1.

Since the vehicles speeds are many times below 1 due to constant breaking that gives the server room to finish its schedule.

 

 

Limitations:

Spoiler

 

- Due to having performance as a focus the script is rather rough when dealing with immersion. (Vehicles hit the brakes and move a little harshly)

- The vehicles move rather slow but that is a sacrifice I had to make in order to keep those checks from saturating the server and also to avoid having to make the vehicles come to a full stop on every obstacle.

- Was tested on a Hosted server with up to 40 vehicles and 80 civilians without performance degradation but more could have a toll on your system.

 

 

Usage:

Spoiler

 

- Put the vAiDriving.sqf file in your mission directory like so: "missionDirectory\vScripts\vAiDriving\vAiDriving.sqf".

- On your initServer.sqf add the following lines:

call compile preprocessFileLineNumbers "vScripts\vAiDriving\vAiDriving.sqf";
waitUntil {sleep 1; time > 1};
[] call vAiDriving_init;

In your mission add the vehicles with Ai Drivers using EDEN and hopefully give them move waypoints on roads. (This Script does not deal with vehicle movement so you will need waypoints or another script for that!)

 

 

Script Optional Configs:

Spoiler

 

Open "vAiDriving.sqf" with a text editor and change these lines to your liking:

vAiDriving_useLinesIntersectWith = true; // Helps vehicles reduce speed when facing obstacles other than other vehicles and men.
vAiDriving_show3DLine = true; // Set to true to draw a visual line for the LINES INTERSECT.
vAiDriving_handleBargates = true; // Should the vehicles open BarGates automatically?
vAiDriving_debug = true; // If you want to see why a car hit the breakes etc.
vAiDriving_handlePedestrians = true; // Set to true to optimize Ai Civilian units and give them waypoints to look "realistic". // New since v12

PS: This script aims towards making the Ai Driven vehicles brake better. If you actually want to make the Ai drive better then you should use @RCA3's amazing AI Driving Control. (Link in spoiler Below)

Enjoy and I am looking forward for suggestions and testing input!

 

Special thanks to @RCA3 again for his work and sharing his amazing scripts and mods with us!

 

vAiDriving version 13 Demo Mission (Malden) DOWNLOAD LINK: https://drive.google.com/open?id=133RUlQmcrzXFxV9RLC27sdIQYOLkFyR5

 

PS2: I haven't tested this script as a CONVOY but I believe it should also help with convoy missions probably. (Please report your results)

[LSValmont 789]

version 12 "Handle Civilians" of the vAiDriving script RELEASED:

 

Release Highlights:

 

- Added the game changer vAiDriving_handlePedestrians param. If set to true the script will automatically optimize all civilians on the mission, turning them into
performance friendly agents that roam the map smartly,  going into buildings, "talking" to other civies and avoiding walking on the middle of roads for long periods.

- vAiDriving_handlePedestrians increases the server FPS even further than before! WAY WAY MORE!

 

- Further optimization and tweaking not worth detailing.

- After this update the number of civilian casualties due to bad Ai Driving is: CERO.

DISCLOSURE: No pedestrians were harmed during the development of this script version. (FINALLY!)

 

PS: Since Ai Drivers are no longer the top predators of Arma 3, players can now be the main danger on the streets again...

ENJOY your newly found Military Simulator first, Destruction Derby simulator second! 😉

Nice work, I always joke about how drivers intentionally drive off the road specifically to kill pedestrians lol. Good job finding a fix.

Thank you @phronk!

 

Yeah it was always funny and sometimes nerve-wrecking watching the Ai Drive over pedestrians. On most missions the civilian population was reduced to half during the first 10 min of a session. 

 

Rather than a fix this is a work-around that sacrifices some stuff in favor of a more grounded and FPS friendly experience. I am sure it will serve many servers and coop missions well.

Nice work man.  Thanks for the contribution. 

 

If you want to improve on the "hits the brakes harshly" bit, you could use setVelocityModelSpace in a tight loop or onEachFrame to slow the vehicle down smoothly in whatever increment you choose.  I can dig up some sample similar code (but not exactly this use case) if you are interested. 

 

In my second Last Tango mission I had a chase sequence where player driving an offroad was chasing a fleeing AI truck.  I used setVelocityModelSpace in two ways:  1) Increase speed incrementally  of chased AI truck so it went much faster in straight sections of road, and 2) slowed player's vehicle incrementally when player too close to fleeing AI vehicle (as it was important to mission that player was not able to crash into the fleeing AI vehicle).

Thank you @johnnyboy , the appreciation is mutual and I still have a long road to travel if I want contribute 10% of what you have around here!

 

I am actually already using  setVelocityModelSpace on the script and it works quite well.

 

The problem is that since this script is meant for multiplayer I had to space checks over 1 sec or more so onEachFrame or tight loops are my mortal enemies. I only every use such loops on my draw3D scripts but nothing else.

 

You would be impressed by the amount of "damage" that a single and even the simplest tight loop can do to a server over two hours of gameplay.

 

In fact CBA, a mod I always found top notch performance wise, has serious issues with its current PATROL/SEARCH fncs just to let you know delicate server performance can be, that even the veterans coders and scripts sometimes fail at optimization some times.

Makes sense.  But...

... I was only thinking of using onEachFrame or tight loops just for the braking event.  So you would sense when to brake however you do it now, then use setVelocityModelSpace in a tight loop momentarily for the braking.  It would not be a constantly running loop or onEachFrame.

 

But its obvious you have thought this through in detail and understand performance impacts far greater than I (especially MP stuff which I am quite weak on).  I'm sure its better how you have it now (just throwing ideas out...not all of them stick!).   Carry on dude! 

 

I need to get back into scripting, but for some reason I haven't been motivated, eventhough I technically have more time for it due to the annoying lockdowns.

Your input is always welcome my friend, specially if I ever get into Single Player mission making. Ever since I started playing arma a couple years ago I never got into Single Player, it is all about the player interactions for me.

 

Anyways about the motivation part... it comes and goes at unexpected moments. Covid is a big let down so even if we have more time now it is also harder to have the will for stuff since we are all kinda depressed.

 

My current motivation is that all these scripts are really for my HUGE Script suite that I plan on using on my next super Multiplayer Mission 😉

 

If you ever wanna combine forces I believe we could do cool things faster than on our own. Additionally I am terrible at the marketing material specially since my english sucks!

 

I could give you a private snippet of what I am working on if you are interested and perhaps could be a motivation to do something BIG.

This is great! Anything that improves the shit driving code (that has vehicles swerving INTO foot mobiles) is very welcome indeed. 

 

Would it be possible to package it up in a mod to work everywhere?

Perhaps... I am in the process of gathering a team so I can get help and help others do things faster and perhaps a mod version too.

Is it compatible with ai driving mod, can i run them together?

You mean the Ai Drive Control mod? Can you link the mod?

[headstone 4]

yes, ai driving control

Then no.

 

This script is compatible with mods that ONLY deal with the movement of the vehicles a nothing else.

 

Ai Driving Control does what this script does (Makes the vehicles brake in time) but also handles the way vehicles interact with other nearby vehicles.

 

So if you have Ai Drive Control you don't need vAiDriving.

 

If you are not having performance problems with Ai Drive Control then there is no point in switching to vAiDriving.

version 13 "Automatic Vehicle Waypoints!" of the vAiDriving script RELEASED:

 

Release Highlights:

 

- vAiDrive now has the option handle the waypoints of vehicles automatically so that players and mission makers do not have to set up each vehicle and each waypoint individually nor have other vehicle movement scripts running.(vAiDriving_handleVehWaypoints=true).

- vAiDrive now has the option to automatically cache vehicles and units to preserve resources when players are far away.  (vAiDriving_handleVehCache=true)

- It is now possible to set the vehicles handled by vAiDrive to never run out of fuel. (vAiDriving_vehUnlimitedFuel=true)

- vAiDrive can now also randomize the look of pedestrians automatically. (vAiDriving_dressPedestrians=true)

- All vAiDrive settings are now set by editing  the "vAiDrivingCONFIG.sqf" instead of the main fnc file.

- Fixed Ai civilians not looking at nearby pedestrians when "talking" to them.

- Fixed Bargates sometimes not being handled correctly.

 

While it started as a simple script to help Arma 3 vehicles brake better, AS OF VERSION 13, vAiDriving has expanded to become a fully fledged CIVILIAN vehicle and pedestrian handling script that does not require any input/extra work from the mission makers to work as intended and to have all its features enabled.

It provides mission makers whose missions involve Ai vehicular driving and/or Ai civilian pedestrians with ALL the tools they need in order to have a more immersive, performance friendly and overall better Arma 3 experience.

Hi, Valmont,

Finally did a little test on your script running your demo mission.

I compared to my script, disabled your waypoints (added manual ones), cache and pedestrians to be fair with mine, and the FPS were not that different. They both variate ~5 FPS while running the mission. The good part is (on my potato PC) I could definitely notice my pointer/mouse to be more responsive while running vAiDriving 🙂. That's probably due to the CBA function(s) keeping everything together while my script is probably flooding the scheduler.

Driving wise they also behaved pretty good 👍.

A quick test with pedestrians only, loved the performance when turning them into agents 👌.

One question: the script does update on spawned vehicles and pedestrians along the mission, right, not just editor placed?

Well done.

Cheers!

I am glad you liked it @RCA3!

 

One key aspect is that I also disable most Ai features on Ai drivers so they are also consuming less scheduler time.

 

The script updates for new drivers/vehicles/pedestrians/BarGates every 300 seconds (5 minutes), It could be set to less and still won't affect performance.

 

Agents are amazing for these kind of scenarios.

 

I am turning @maxjoiner's aliens into agents now and they will be deadly! (While also performing 3 times faster).

With handleVehWaypoints and handleVehCache both set to false, distant vehicles are stopped until a player comes near enough. Is this intentional?

This is quite an exciting script, but the above mentioned behaviour breaks any mission design that expects certain vehicles to be able to move regardless of where the players are.

 

Additionally, the script seems to mess with drivers that are being handled by Silola's DAC. When a player moves near, it may take a while for the driver to start heading towards its waypoint. Upon reaching the waypoint, the driver won't get out and patrol as it's supposed to, which effectively prevents it from following any more waypoints.
