Shooter AI – The Ultimate Artificial Intelligence Solution

Hi was wondering if it would work well with my game
http://www.kongregate.com/games/pvtctrlalt/toy-box-tanks
if so ill buy right away

 

This might be a bit silly, but until your announcement just now I did not even know there was a multiplayer version of Shooter AI. I bought the normal Shooter AI for integration in a multiplayer game, is that particularly hard to do, or do I really need the multiplayer version?

 

@Pulov -
Sounds like a great idea!

@PvTGreg -
For your game Shooter AI would work, but as it is optimized for first-person shooters it might not be the best for your type of game.

@OnePxl -
Shooter AI Multiplayer is better optimized for multiplayer use. This is our overview video for it:

Thanks!
Ryan

 

@Pulov - Anybody that has purchased 1.x can see for themselves, right now!

@OnePxl - As Ryan said, the Multiplayer version is highly geared towards multiplayer. You could do the multiplayer yourself, though it might take some time to get into SAI.

 

I watched the overview video, but that mentioned it was a single script (add-on) with a network view to sync up Shooter AI over the network. I guess that has changed? Or is the idea still fundamentally the same?

 

and where might that be, nikita. i just purchased ac ouple of days ago the asset @ the store.

thanks

 

After updating to UFPS 4.8 I'm no longer able to apply damage to the AI
This is the error message I keep getting

Code (CSharp):

1. MissingMethodException: The best match for method Damage has some invalid parameter.
2.

6. vp_HitscanBullet:Start() (at Assets/UFPS/Base/Scripts/Gameplay/Combat/vp_HitscanBullet.cs:68)

Any help would be appreciated thanks.

 

@OnePxl -
Idea is still fundamentally the same.

@emmcd3 -
If you're talking about the download link for the beta just send me your order confirmation and i'll send you the link.

@CreatureSurviive -
We'll look into it and hopefully get back to you asap with a solution.

Thanks!!
Ryan

I wouldn't publish my invoices here in a public forum due to your private data...

 

ty corrected it...

sent Ryan a pm...

 

Much appreciated. Its' a secondary account not linked to anything of substance. But, thanks for the action. I guess I was a bit impatient.

 

I have the same issue as CreatureSurviive regarding UFPS 1.4.8.

I purchased it during the sale then I saw that AI shooter supposedly works straight out of the box with UFPS.

So I also bought AI Shooter but it does not work as seamlessly as you suggest. I know its a new update and it's bound to have broken things but to advertise that it works as it does on your YouTube tutorial video is kinda misleading..

Well anyway following the YouTube tutorial there are 2 issues:
- Can't do damage to enemies.
- Can't reduce enemy damage to player.

 

Found out how to get the latest UFPS Working with Unity 3d,
Took me a while but,
In the VP_hitscan script,
From this

// do damage on the target
if(m_Sender != null)
hit.collider.SendMessageUpwards(DamageMethodName, new vp_DamageInfo(Damage, m_Sender), SendMessageOptions.DontRequireReceiver);
else
hit.collider.gameObject.SendMessageUpwards(DamageMethodName, Damage, SendMessageOptions.DontRequireReceiver);

Change to this

// do damage on the target
if(m_Sender != null)
//hit.collider.SendMessageUpwards(DamageMethodName, new vp_DamageInfo(Damage, m_Sender), SendMessageOptions.DontRequireReceiver);
hit.collider.gameObject.SendMessageUpwards(DamageMethodName, Damage, SendMessageOptions.DontRequireReceiver);
else
hit.collider.gameObject.SendMessageUpwards(DamageMethodName, Damage, SendMessageOptions.DontRequireReceiver);

 

In vp_hitscan round 163
Change it to

Code (CSharp):

1.  
2. // do damage on the target
3.  if(m_Sender != null)
4.  //hit.collider.SendMessageUpwards(DamageMethodName, new vp_DamageInfo(Damage, m_Sender), SendMessageOptions.DontRequireReceiver);
5.  hit.collider.gameObject.SendMessageUpwards(DamageMethodName, Damage, SendMessageOptions.DontRequireReceiver);
6.  else
7.  //Debug.Log( hit.collider.gameObject, hit.collider.gameObject);
8.  hit.collider.gameObject.SendMessageUpwards(DamageMethodName, Damage, SendMessageOptions.DontRequireReceiver);
9.  

 

Hi I'm just trying to get ufps and shooter ai and make a quick example as I'm still learning, but I've ran into this error after trying to set-up the ragdoll and shooter ai.



Also, does anybody have any good zombie settings they would like to give away?

 

@Jarretxx

Cheers it works!

I had spent quite a lot of time converting it so that the player uses the AI Shooter health/damage system instead lol. Well least that activity helped me get to grips with the code and how things actually work.

 

@Everybody

Just got back from a short holiday, made some small updates to SAI 2.0 beta and heres the new tutorial for UFPS integration:

Special thanks to Jarretxx!

Also, post your requests for tutorial videos!

Thanks!
Nikita

 

i was watching tutorial, then ufps tutorial integration suddenly disapeared ! your documentation suddenly disapeared !

please check your links.

do you have an estimation for 2.0 release? is it a breaking release?

 

@Damien Delmarle - I had to reupload because we had some audio issues.

The 2.0 release will be breaking and its our goal to send the update away this week, though it all depends on the new demo we're making.

 

New quick setup tutorial for 2.0!

 

@Hypothesys -
Would be possible to do so but it depends on the pathfinding system you are using.
But we have not planned to implement flying enemies, as we focus on humanoid enemies.

Thanks!
Ryan

 

any tutorial for non humanoid characters without ragdoll setup? ( its a request if there isnt yet)

i followed the tutorial above:
when i create the character ai there is an error about editor:

I am using the 2.0 beta multiplayer

 

i found the solution to the problem, i used a character which after exporting it from fbx to unity prefab has a transform hierarchy correctly setup, just the rig was not correctly setup, neck reference wasnt assigned into the mecanim avatar definition. now the error is gone.

 

one little thing for UFPS users, do we have to use a collider on our player ? it would be nice if you allow to enemies or players to be registered as enemies by the function: public GameObject GetEnemyWithinEarshot(stringtagOfEnemy) from the script GatewayGamesEars
even when they use a character controller instead of a collider.

you could do a check for CC component in you foreach loop before using a collider.

my player stop after reaching it first waypoint which is above the ground, any idea what should cause this ?

 

@Damien Delmarle -
Yes you do have to use a collider when using UFPS.
It might be that the second waypoint is too close to the first one this might cause some problems. So just try increasing the distance between your waypoints a bit and let me know if it worked.

Thanks!
Ryan

 

@Everybody -
If you are using the ShooterAIV2 Beta, it now includes a Demo scene. I recommend taking a look at it as it might help with some of your problems.


Thanks!
Ryan

 

@Everybody -
The link for the demo will be posted in the forum as soon as its finished.


Thanks!
Ryan

 

there is definitely no option to add a collider on the UFPS player setup. if you try to add it the character controller will collide with the collider and this will count as fall damage, killing the player itself one second after scene has started.
the waypoint is fixed by increased distance thanks anyway.

 

@Damien Delmarle - Sorry, I think we misunderstood your question. For UFPS you don't need a collider as its built in with the package. You only need one if you're making your own system. If you follow the YouTube tutorial you'll see everything needed for UFPS integration.

@Everybody - We're coming very close to release and are crunching bugs as quickly as we possibly can. Also, we're proud to announce a new feature which you've been asking for since a veerrrry long time: AI communications! Now the AI will call reinforcements when it faces an enemy and there are free AI within a certain radius.

Also, little screenie preview of the first demo scene (amount of AI will be increased):

Hi Nikita,

On the attached, you'll see a couple of exceptions thrown regarding "tagOfBullet". I have hacked a couple of quick workarounds, but, this would not be the test environment that I should use if I were to return any reliable results. The exceptions occur if I overlay 2.0 on the Asset Store version(1.5.2) or separately run.

Your recommended fix or advice will be very much appreciated.

 

@emmcd3 - Thank you for the input, its now fixed in the latest version.

@Everybody!!!!

First off, special thanks to everybody who participated in the beta. You provided us with valuable data, and we were able to make this product much better.
Secondly, thank you every customer who has bought SAI in the 1.x cycle, and tolerated all the bugs and quirks.

We have just uploaded and sent the latest version of SAI 2.0 to the Asset Store team, and are now awaiting their approval for the update to go live. As said before here are 2 new demo scenes:
AI vs AI: https://dl.dropboxusercontent.com/u/86419401/Demos/V2/AIvAI/AIvAI.html
UFPS with SAI: https://dl.dropboxusercontent.com/u/86419401/Demos/V2/SAI-UFPS/SAI-UFPS.html

The AI vs AI is included with SAI, and the ufps one is just based on that.

WARNINGS:
- Once the update is accepted, the new price of Shooter AI will be $50, and Shooter AI Multiplayer will be $70. If you haven't got Shooter AI yet, we highly recommend getting it at the lower price.
- We will be phasing out the tutorials for 1.x in the coming weeks. Please tell us which new tutorials + features you want.

Thanks!
Nikita

 

Hi - This is good news, I'm a fan of shooterAI since the beginning, but I think you should enhance the UFPS demo a bit. The AI enemies are weak, their shooting rate is low, they don't move much. It's too easy to kill them all, so the AI seems dumb, I know it's not but testing the demo doens't give a good impression of shooterAI.

And maybe you could use the incredibly good new demo level of UFPS in it's latest version to show off how dynamic your AI actually is ? http://www.visionpunk.com/products/ufpsc/webplayer/demo.html

 

@XenoGalaxies - Thanks for the feedback.
I'll contact UFPS to ask whether we could use their demo, and i'll also improve our current one as well.

 

New tutorial out from Pärtel Lang!

 

A question about the coming V2. Will the KI also be adjusable with Behavior Designer. I think I read, that V1 was...

 

@red2blue - The IK is adjustable via scripts provided on the model, as seen in the tutorial i posted above. With the correct scripts, you can adjust the IK with BD.

 

Hi nikita,
sorry there was a misspelling from my side. I meant the AI (KI is the german word for AI ). Will it be possible to tweak the AI behavior with Behavior Designer. I guess this was possible within Version 1, or am I wrong? Sorry for the confusion!

 

Hi

When is the expected release and how do I update? It's just I have SAI and recently began a project but I don't really want to work on it without seeing what this version has in store.

One thing I've always found confusing is how all the attributes come together to create a personality. Compare it to say Unreal Tournament (99) where you select a fighting style (cautious, aggressive, etc.) and set aim, strafing, jump, etc. How can I make say a 'cautious' AI personality in SAI?

 

If the developer send the asset to unity, it is up to them how long it will take. It could be days up to weeks, depends on the complexety of the asset.

You can update the asset if you click within unity under the menu "window" --> "Asset Store". In the upcomming window is a download symboled button. The first of the three on the top right. There you can see your purchased assets. If there is an update for the asset it will say "There is a new version available". Just download the update and reimport the asset.

Hope this helps!

 

using 2.0 beta i make a new character, if enemy data have the value search automatically for new enemy set to "true" i have the error:

NullReferenceException: Object reference not set to an instance of an object
GatewayGames.ShooterAI.GatewayGamesEars.GetEnemyWithinEarshot (System.String tagOfEnemy) (at Assets/Shooter AI/Scripts/Sensors/GatewayGamesEars.cs:82)
GatewayGames.ShooterAI.GatewayGamesEars.Tick () (at Assets/Shooter AI/Scripts/Sensors/GatewayGamesEars.cs:44)
GatewayGames.ShooterAI.GatewayGamesBrain.Update () (at Assets/Shooter AI/Scripts/Brain/GatewayGamesBrain.cs:199)

 

In 2.x there's a bug which crashes the whole demo scene, I think it's on the OnTriggerEnter function in the health manager because I commented that and now it works perfectly

 

found the solution to my problem earlier, I had to currently assign manually the "current target" in the inspector, is this normal?

 

@Everybody! SAI 2.0 is finally out! Everybody that currently has SAI gets this update for free.

@red2blue -
1) We haven't made BD integration yet, though its on our plans in the next couple of months.
2) Thank you for helping with the forums!

@Ultimar235 - Out now!
Also, if you try out the new version, you might find it a bit easier to customize. Contact me directly and we can make some specific behaviours.

@Damien Delmarle -
Thats really weird. Looking into it now, though it looks like you haven't set up the tags correctly for the enemies. Try updating to the newest release from the Asset Store, as it may have been a beta error.

@thendricks -
Was it the GatewayGamesDamageRegion script? Thats the only health related script that has OnTriggerEnter.
I've tried it out and we can't get any errors. Are the tags setup for bullets?
Its not a critical piece of code though, as its only used for projectiles (arrows etc..).
If the problem still persists, try reimporting SAI. If the errors continue, contact me and we'll get it fixed.

 

enemy (ai) is tagged Team1 player tagged Player, i have checked the inspector using dictionary into variable, so the tags are not hardwriten into code right?

is the asset store version also the beta ?

 

@thendricks - If you'r e referring to tagOfBullet related exceptions you have to go set in Tags. I think slot three is the one that oddly empty. Put it in (capped "B") and off you go if I'm the above.

 

I think anyone might find an upgrade from 4.5.1.3f to 4.5.5 a very good idea. I was getting a bunch of buggy errors referencing bad audio drivers and other nasties.

 

Could i use this system as a standalone, like attach only one script to the hero, give it the enemy positions at each frame with additions to your script and get back the place he should go for cover ?

Thanks

EDIT: I just realized i had already bought the asset , so i can implement the answer right away

 

my enemy almost never hit the player except if i am in very short range, can i increase weapon range somewhere?

 

@damein Delmarle -
1) No the tags are definitely not hard written into the code.
2) The asset store version is the full release.
3) If you're having problems with aiming, go to you AI's brain -> Emotion Data -> Set "Emotional Effect Factor" lower. Try playing around with the values, as this affects how much adrenaline, fear etc.. affects the AI.

@nasos_333 - Use it as much as you want! Look into GatewayGamesBrain on how we optimized and implemented it.

@emmcd3 & thendricks -
Thank you very much! I've just noticed that we shipped the wrong script for an import script. Replace the code in "GatewayGamesProjectImport" with the following:
