[WIP] bCombat infantry AI Mod [SP]

[SteveJA 12]

Hello fabrizio_T

I would lkie to thank you for releaseing your work as it is very gratefully received. AI has always been a fascinating topic for me but as we all know, Arma's AI has always been inconsistent in terms of ability. At times it shines with moments of brilliance and the next, it does not. I believe that you work has really pushed the AI into behaving more human like and more intelligently. For that you can really be proud for few people have manged to have such a positive impact on the AI's ability. I, and I'm sure a few others here, will look forward to see what other brilliance you can conjure.

Holy sh1t AI now throws nades and uses buidlings :) Man you are awesome!

[fabrizio_t 58]

Thanks to everbody giving feedback and to those taking some time to vote the poll.

So far looks like most people enjoyed bCombat, so it's likely i'm going to spend some more time in order to further refine it.

[twisted 128]

Im enjoying this mod. it seems it makes comabt alot more chanllenging. one of the must have mods for arma3.

one thing is i keep getting an OK dialogue in combat (thats all just the word ok) and i have to click accept to carry on. really breaks immersion.

I'm very sorry for that issue.

I'm positive that's triggered by any non-zero bcombat_cover_radius second parameter values.

Easy way around is putting that second parameter back to zero, example:

bcombat_cover_radius = [15,[b]0[/b]];

Alternatively you may just comment or remove "hintc" command at line 506 of lib\common.sqf, not to lose any functionality.

Thank you.

Looking at the poll, there are two noobs that have voted 'Very Disappointing'! They have to be kidding!

[potemps 1]

Becouse of this mod - I'm thinking now about buy arma III :D Tell my guys, how AI behaving in open areas, such forest etc. Do they have any behaviour when they spot a Tank or something ?

Will 0.15 be available for everyone to download like 0.14?

[fabrizio_t 58]

Will 0.15 be available for everyone to download like 0.14?

I'm evaluating how to handle v0.15 release.

I think best option would be a private RC version released to testers in order to ensure no critical stuff is broken, followed by public release within a couple days.

This as long as testers are willing to give further support for next build.

v0.16 will be a consolidation release, so private testing should not be needed anymore.

I would like to know the causes of such a negative experience.

Maybe they'll post some feedback, it would be useful.

However, that's just matter of tastes, not everybody will like this.

Of course we are here to privately test as usual Fab. Ready when you are.

I just can't understand those that put 'didn't like it'. Seriously? You take a basic AI and actually make it intelligent, and people don't like it? Would be interested in finding out who voted that way.

Ty.

Maybe they did't got it working, or they expected something different.

Rather than "who" i would like to know "why": any negative impressions can eventually help improving stuff.

However most people seem enjoying bCombat and about 1 thousand downloaded it without anybody cursing me (till now).

So far so good. Now i'm less concerned about open beta.

Hey Fabrizio.

Some basic feedbacks on v0.14 :

1/ Awesome AI in Urban or Forest battle. They seem a lot more responsive and aggressive. They look a lot more human like. Good job on that.

2/In my opinion they throw nade just a bit too often.

3/In the single campain, with only bCombat and JSRS2.0 activated i can't pass through the 2nd mission "SItuation Normal".

When i arrived at the survivor group they don't react in any way. It could be a problem on my side though so ill keep checking.

Ok the issue was that Adams died from a grenade in mission 1. I did it again without having Adams killed and the next mission played well.

3*/ Adams can be killed by grenade in mission 1 when he is necessary to start mission 2 "Situation Normal"

Ill keep testing the whole campain and write my feedbacks in this post.

All in all, excellent job. If you keep improving the AI like that, maybe they will soon be able to fight inside buildings! :o)

Fabrizio you made it!, I have played bohemia games since Op. Flashpoint and this is the first time ever that the A.I. is very smart and challenging.

Amazing work, definitively you have to get a job as game programmer. Thanks for making and sharing.

I just set up a very quick mission (using my beloved VTS) with 2 rifle squads facing eachother, buildings in between. The fire fight between them was amazing (you guy HAVE to use Blastcore and JSRS :) ) I do my usual move into camera mode to 'voyeur' the action and I was astounded by how clever the AI was. Very intense action. The only improvement I could see was what you already have put into 0.15, which is CQB reaction quickening.

I'm one of them:(, I played Combined Arms, one of the showcases mission, and with bcombat in only two or three minutes the fight was over, it was like a battle between two snipers teams, I was the only one remained alive and two enemies. Then I used ASRAI, TPW and wwaicover, with some changed configurations, and fight lasted much longer, ~15 min. Don't get me wrong, with b-combat Ai reacts great, but fight it ends too soon for me. I'll try the new version and I hope to change my opinion, and thank you Fabrizio for the hard work. By the way, I'm not a noob, Kremator:p

[jake_krieger 10]

@Gulag you probaly have a very high precision setting in youre configs.

Fabrizio please release difficulty/precision config files or just the lines

to get bCombat properly and in a realistic way working for all users.

[gulag 10]

@Gulag you probaly have a very high precision setting in youre configs.

This isn't the problem, I noticed that with b-combat, they attack too fast and get too close to the enemy.

Cheers gulag, nice to hear from you.

bCombat usually leads to longer firefights, one of the reason being accuracy is sensibly lowered.

May i ask you some questions in order to understand what's going on?

* Which difficulty settings you play on?

* Have you manually set precisionEnemy or PrecisionFriendly? If so, which values ?

* When you tried bCombat, did you had any other AI / skill mods running ?

Thank you, it was nice to get your feedback.

EDIT:

i've just run the same mission, on normal difficulty. I think all worked as expected and played well (so well that maybe i'll run it again and post a video later).

I was finally killed after 834 seconds (which is a little less than 14 minutes), when we were basically assaulting the compound.

6 men from my team were still alive, 1944 bullets were fired in total and 28 men killed, which makes for about 70 bullets/kill ratio.

I think there may be something wrong on your side, maybe bCombat is not running correctly.

Do you have CBA installed ?

Did you see the hint "bcombat XX has started" at top-left of the screen at the beginning of the mission ?

Did you saw debug balloons?

Care to retry and tell me the number of fired bullets and casualties?

Thank you, sorry for the amount of questions, but i'd like to get your issues sorted.

[kremator 1065]

By the way, I'm not a noob, Kremator:p

I'm afraid that you have set your AI skill levels too high ... and therefore I will still have to dub you a noob ;)

[gulag 10]

* Which difficulty settings you play on?

* Have you manually set precisionEnemy or PrecisionFriendly? If so, which values ?

* When you tried bCombat, did you had any other AI / skill mods running ?

regular, friendly 0.80 and enemy 0.70, without other Ai mods. I'll try again.

EDIT

Ok, I just played now, only assaulting the compound, I'm alive, (and not drunk, this time), with 5 men from my team alive, 680 seconds, fired ~2085 bullets (w 1486 e 680) 44 men killed.

well ... It seems that the problem (besides..:803:), was the "bcombat_config" file, I suppose, I did something with it, but now for me is solved, thank's Fabrizio for patience.

I liked how the assault occurred, they used concealments tactics and flanked on the right side of compound. Thank's again Fabrizio.

Kremator, don't say a word, it's a million to one......:Oo:

Guys it would be nice to see what values people are running and compare to get a idea of good balance of bcombat. Here is mine but not sure yet still tweaking did 2 hours of testing last night changing numbers and all. What I have a problem with is this array thing I will post that to or rather my whole config maybe someone can help me balance this out and get a good fight. One point in tweaking the grenadier shot his grenade launcher in begging of firefight then he didnt use it again so I have no idea what triggered that,but that was nice.

[twisted 128]

thanks for the fix. its working great. lobing it.

i however do agree with a couple comments on that it makes AI way more accurate. im normally shot while hiding behind a tree or rock from 300m away. i usually set AI skill to 0.3 and their aiming to about 0.3 or 0.5 for snipers and have longer firefigths. but here its zap, zap, dead. it's only with bcombat.

could you advise me what changing each of the 4 values in the skill config are? i've tried lowerign things like aim accuracy but no dice.

are class CfgAISkill

{

aimingAccuracy[] = {0,0,1,0.7};

aimingSpeed[] = {0,0.3,0.6,0.5};

aimingShake[] = {0,0,0.7,0.4};

endurance[] = {0,0,1,1};

spotDistance[] = {0,0.1,1,0.5};

spotTime[] = {0,0.2,1,1};

courage[] = {0,0,1,1};

reloadSpeed[] = {0,0.2,1,1};

commanding[] = {0,0.3,1,1};

general[] = {0,0,0.6,0.7};

};

Hi fabrizio_t, and sorry for the intrusion. One of your testers found an incompatibility between your Mod and TMR (both in the old unsupported version and the new version cambam47 is working on): apparently your Mod disables all feautures of TMR, save for 2D scopes (that lose their reticles anyway).

A similar post was written in TMR - Alternate thread (link), so if you felt like it you could try and work out the incompatibility with cambam47 himself.

Here is the original incompatibility report. Keep up the good work!

Yay!

[potemps 1]

Guys, how i can entirely disable the whole debug, i deleted this line in config file but it's still apears...and its quite annoying for me :)

[kremator 1065]

//[] spawn bcombat_fnc_debug_text; // Uncomment this line to activare bCombat debug text overlays (as alternative to bcombat_fnc_debug_balloons or bcombat_fnc_fps)

//call bcombat_fnc_debug_balloons; // Uncomment this line to activare bCombat debug balloons (as alternative to bcombat_fnc_debug_text or bcombat_fnc_fps)

//call bdetect_fnc_benchmark; // Uncomment this line to activate bDetect live stats panel (as alternative to bcombat_fnc_fps)

// [] spawn bcombat_fnc_fps; // Uncomment this line to activate FPS stats panel (as alternative to bdetect_fnc_benchmark;)

Do that in config.sqf

@Gliptal it is probably something to do with eventhandlers. Check that cambam is adding them instead of overwriting eventhandlers.
