[RELEASED] Emerald AI 3.2 (New Sound Detection) - The Ultimate Universal AAA Quality AI Solution

@BHS Okay, I have enabled all Debug tools and no targets or obstructions are being logged.
Also, according to the documentation for draw raycasts: "A green line indicates that the AI's sight is not obstructed. A red line indicates that an AI's line of sight is obstructed." But my AI's raycast line is yellow.

This was working fine before the update - is there something else that needs to be reapplied or whatever? I have done all animations and attacks.

 

It's definitely LoS related because if I set it to trigger detection it works immediately.

 

Strange, I will look into this right now.

 

I've tested this and the AI detect their targets right when they are with their LoS. Have you reapplied your AI's factions to their faction relation list? This is required due to the new faction system with 2.4.

 

Yes, your demo scenes are working too. Not sure what's wrong.
How about my AI's raycast line being yellow instead of green or red? What does this mean?

EDIT: Also have you tried with stationary (but still aggressive and foolhardy) AI?

 

I've updated the Emerald AI Wiki to explain the other colors. The yellow line is used for the AI's line of sight to its look at target, when using the Head Look feature. An orange line is cast for each target within an AI's detection radius until they are visible by the AI, when using the LoS feature. I have tried the Stationary Movement Type and everything is working correctly on my end.

Are you using custom faction names? I've discovered a bug with 2.4 that sometimes doesn't allow the Faction Data to sync correctly. Is your Faction Manager data and your AI's faction enums displaying the same faction names? I have a fix that will be submitted today to address this.

 

@BHS No, all I am using is creature faction and then the player.

I think I may have solved it though. I am using Unity's Character Controller to control my player instead of a Rigid Body. I added an additional collider and then LoS detection worked. It seems that the capsule collider used on the character controller isn't detected by Emerald like a normal collider is, even though they are the same layer.
Not sure why it works up close though, and also why trigger works with character controller detection but LoS does not.

 

On that note of Factions, I've been trying to setup Avoidance for my AI's using Factions and putting them all in one faction. The goal is to have them attack the player which they do, but to keep it a first come first serve basis so the player isn't overrun with all the baddies at once and they will back off if they detect they are close to one another. But I can't get this to work.

 

You can use the "too close" setting so they will back away, it works well. As far as the "first come first serve basis" you can use detection radius and behavioral settings, as line of sight wouldnt work well in that senario.

 

The Character Controller Collider component doesn't work the same as other colliders so it's not going to be picked up by Emerald AI's detection system. Good to hear you were able to resolve this.

 

Hey everyone,

Emerald AI 2.4.0.1 has been submitted and is awaiting approval. This small update fixes the issues introduced with version 2.4.0 as well as two new functions added to Emerald AI's Event Manager script.

Fixes

• Fixed an issue with the Run Attack Animation Event warning that would be displayed, even if the proper event was created.
• Fixed an issue with the Faction Data not syncing or updating newly added factions properly.

Additions

• Added GetAIRelation(EmeraldAISystem EmeraldTarget) to the EmeraldAIEventsManager to get an AI's current relation to the EmeraldTarget relation.
• Added GetPlayerRelation() to the EmeraldAIEventsManager to get an AI's current relation to the player.

I'm having a tough time trying to get this to work with horror fps kit. Any help is appreciated.

 

@BHS, haven't received a follow-up about whether or not the stop and turn-to-face functionality has been added. I'm still running a little hack for that, but would like to know if you squeezed that in. I also found an issue with the logic in the CameraShake component and hacked in a little fix for that as well. The way it caches you init camera position before the shake occurs works well if a single shake is permitted to finish before another one starts. If a shake occurs while you're camera is already in the shake process, the new shake will cache your wobbled camera vector. So I just tossed in a quick bool to check "isShaking" and it updates to false only after the shake and camera reset are done.

 

Hey guys I finally figured it out. I just had to script it in. I used the BH_Body to tell when the enemy was struck and I just used the attack animation on the enemy to tell when the Ai is attacking. Don't ask why I didn't just use animation for both.

 

I am trying to setup my Companion AI's a little differently. My intentions are to have the AI's wandering around, and when they encounter the Player, they will fire up a Pixel Crushers Dialogue System conversation and that will flip an "inParty" variable to true. Once true, the behavior should change to Companion.

I found this old 2008 code snippet, but it doesn't work...

Code (CSharp):

1.  
2. GetComponent<Emerald_AI>().SetFollowerCompanion(GameObject.Find("Player").transform);
3.  

How do I do this in 2.4?
Mark

EDIT: Also tried:

Code (CSharp):

1. [/COLOR][/FONT][/LEFT]
2.                 if (!jonahInParty)
3.                 {
4.                     EAIsys.CurrentFollowTarget = null;
5.                     EAIsys.Wander();
6.                 }
7.                 else
8.                 {
9.                     //EAIsys.FollowCompanionTarget();
10.                     EAIsys.FollowCompanionTarget();
11.                     JoinedParty = true;
12.                 }
13.  

​

 

I made a limb based damage system for EA, just attach this to all the body parts, make sure the limb is setup like a ragdoll and has a collider and rigidbody.

Code (CSharp):

1. using UnityEngine;
2. using EmeraldAI;
3.  
4.  
5. [RequireComponent(typeof(Collider))]
6. public class EA_LimbDamage : MonoBehaviour
7. {
8.     public EmeraldAISystem AI;
9.  
10.     public BODYPART BODY_PART = BODYPART.BODY;
11.     public enum BODYPART
12.     {
13.         HEAD,
14.         BODY,
15.         ARM,
16.         HAND,
17.         THIGH,
18.         LEG,
19.         FOOT
20.     }
21.     public float DAMAGE_MULTI = 1f;
22.     public bool AUTO_SETUP_MULTI = true;
23.  
24.  
25.     void Awake()
26.     {
27.         if (AI == null)
28.         {
29.             AI = transform.root.GetComponent<EmeraldAISystem>();
30.             if (!AI)
31.             {
32.                 Debug.LogError("CANNOT FIND EMERALD AI. ");
33.             }
34.         }
35.     }
36.  
37.     void Start()
38.     {
39. if(AUTO_SETUP_MULTI)
40.         SetupMulti();
41.     }
42.  
43.     public void SetupMulti()
44.     {
45.         switch (BODY_PART)
46.         {
47.             case BODYPART.HEAD:
48.                 {
49.                     DAMAGE_MULTI = 2.0f;
50.                 }
51.                 break;
52.             case BODYPART.BODY:
53.                 {
54.                     DAMAGE_MULTI = 1.0f;
55.                 }
56.                 break;
57.             case BODYPART.ARM:
58.                 {
59.                     DAMAGE_MULTI = 0.5f;
60.                 }
61.                 break;
62.             case BODYPART.HAND:
63.                 {
64.                     DAMAGE_MULTI = 0.1f;
65.                 }
66.                 break;
67.             case BODYPART.THIGH:
68.                 {
69.                     DAMAGE_MULTI = 0.8f;
70.                 }
71.                 break;
72.             case BODYPART.LEG:
73.                 {
74.                     DAMAGE_MULTI = 0.5f;
75.                 }
76.                 break;
77.             case BODYPART.FOOT:
78.                 {
79.                     DAMAGE_MULTI = 0.1f;
80.                 }
81.                 break;
82.         }
83.     }
84.  
85.     public void Damage(float amount)
86.     {
87.         if (AI != null)
88.         {
89.             AI.Damage((int)(amount * DAMAGE_MULTI), EmeraldAISystem.TargetType.Player);
90.         }
91.     }
92. }

Then in your code to attack, add

Code (CSharp):

1. EA_LimbDamage.Damage(YOUR DAMAGE AMOUNT);

You can either manually set each limbs damage multiplier, or it can set auto on start based on which limb it is. You can change the code to set your own damage multipliers.

 

Hi, I have found what causes this, if you have a ai with both selected and are using run attacks it will cause an error saying it cant find the animation..

EmeraldAISystem

Code (CSharp):

1. CurrentAnimationClip = AIAnimator.GetCurrentAnimatorClipInfo(0)[0].clip;

i changed the error code to this

Code (CSharp):

1. if (AIAnimator.GetCurrentAnimatorClipInfo(0).Length > 0)
2.                 {
3.                     CurrentAnimationClip = AIAnimator.GetCurrentAnimatorClipInfo(0)[0].clip;
4.                 }

What happens is it shows the error code and the ai just goes into T pose, and sometimes it sounds like the ai is running or walking but it doesn't move.

If I remove the run attacks it works ok, but every now and again i will receive damage from far away, and the ai is just attacking nothing in one place.


plus the animation event errors are still showing, i've just commented the code out for now,



Cheers Jim

hmm, there seems to be a regression with ranged attacks, they aren't working anymore

 

Hello everyone. I was using Invector's AI before, but unfortunately it wasn't working all that well with VR.
So I'm trying Emerald AI now, and wow it's a lot more complex. it's also a lot deeper, which I do appreciate, but getting the basics done takes a lot more time.

I'm running into the issue where the character AI is not really walking on the ground itself, but hovering slightly above it, any tips on this? I turned on the follow terrain, and while this does follow bumps, it still hoevers above.

 

Likely your AI's collider needs to be lowered or decreased in height

 

Thanks @Alexandus, sdjusting the navmesh offset worked. Cheers

Having the same issue. The AI doesn't seem to attack me at all. Takes the stance, but then does nothing.

Also having issues with Detection. AI only detects the player half of the time.
Trigger works fine, but field of view doesn't.


Also, does Emerald support a cover type system for enemy AI? So spots where they hide behind?

Edit: Detection issues seems to be related to having an active collider on the controller. I was using a VR controller, which don't have those (fortunately it can be set to be a trigger, so it doesn't mess up controls), adding one seems to solve the detection issues with line of sight. Interesting that it worked fine with trigger, and that the AI can detact the player just find while in combat.

 

To anyone interested, in addition to my Playmaker actions for Emerald AI, I am now developing a full set of AI extensions for Emerald AI with integrations with various other assets. This new project will include the Playmaker actions as an optional add on. The project is called LifeLink. I don't want to pollute forums with more information, so if anyone wants to see the basic idea behind the project and discuss it, please go to my new Discord channel:

anyone please help

 

How would you go about setting up a flying enemy? There don't seem to be any settings for this to use on creatures such as dragons.

 

Use the Y offset

 

Use the NavMesh, and player offset

 

I've seen this as well, probably the source of the problem with ranged abilities in this update

 

@BHS Please see above

 

Emerald Ai and Invector integration. followed all the instructions but the AI will only damage the player when the player attacks them. but if they start the combat and the player does not attack them, it will not cause damage. any solution for this guys?

 

@BHS I am getting this error when the melee attack happens and the AI stops attacking. I am using the RFPS integration and it works fine. It just dies out when the AI gets to close when doing the animations.

Unfortunately, I didn't get the chance to add this in with 2.4.0. If you want, PM me the updated code so I can see specifically what was done so I can try and squeeze it in with the next update. As for the camera fix, thanks. I'll add this in with the next update.

 

Take a look at the Emerald AI API here: https://github.com/Black-Horizon-Studios/Emerald-AI/wiki/Emerald-AI-API. It has tons of code snippets and examples to do what you want.

You can set a follower using this: https://github.com/Black-Horizon-Studios/Emerald-AI/wiki/Emerald-AI-API#SetFollowerTarget

It's as easy as the code below. See the links above for an example on how to access the EventsManager script.

Code (CSharp):

1. EventsManager.SetFollowerTarget(Transform Target)

 

Thanks for the bug report, I will look into this. What's strange is that I tested the run attacks quite a bit with various characters and didn't receive this error, but I will try to recreate this. How many run attack animations does your AI have?

While adding if (AIAnimator.GetCurrentAnimatorClipInfo(0).Length > 0) works, it adds quite a bit of garbage, according to the Unity Profiler, and only prevents the error from being displayed when an animation is missing. I'll look into a solution for this though.

 

Can you please provide more information regarding this?

 

Do you have any other components on your projectile? You shouldn't have any colliders or rigidbodies as Emerald AI adds these at runtime. Can please you provide steps to recreate this, if possible?

 

In order for AI to attack a player when they enter their detection radius, they need to have an Enemy Player Relation: https://github.com/Black-Horizon-St...-Faction-Manager#setting-up-faction-relations

 

My guess is that Emerald AI is detecting the wrong collider object of the RFPS system. Double check that it's grabbing the right object by enabling all of the Debug Tools (Located at the bottom of the Docs tab). This is debug log the detected target to the Unity Console.

 

I have the same issue. There are no errors, the AI simply stands there in their combat animations, but the attack animation doesnt start, nor do they shoot.

 

@Penhoat watch my video. Does it look like that? My AI's attack but then stop... @BHS i turned on debugging and nothing? I bet the same would happen with your RFPS instance. If not, I can send ya my project... Its broken not matter how I shake it.

 

Nah that's a different issue. Mine is like @Alexandus where the ranged attack simply doesnt start.

 

+1 they move around but don't initiate ranged abilities. Melee still works

 

Hey, Thanks for your response I have had the errors using multiple ai and each have between 1 and 3 run attack animations. I can send you a prefab of one of them to get the settings if you like. Not sure if it has to do with ranges.

Anyway thank you for awesome ai system

 

@BHS Found out what my issue was! What do you have slated for next update?

 

It seems if the AI is set for both Melee & Ranged, it is being set back to Melee only during runtime. At least in my project. It didn't always do this, and my code is modified, but that is what I am seeing. Hope it helps...

Mark

 

the Casting Effect Direction of the Ranged AI is Sometimes Right and Sometimes Wrong ?! How can I Fix it ?!

 

My AI's that encountered this bug are set to ranged only

 

I have the Jurassic Pack 1 and first, the animations for the TRex and Spinosaurus look odd when walking. Next both seem that they can't attack my RFPS character. They just continuously walk on top of my character. The Raptors dont seem to have any issues. Any ideas?

 

Hi,
Do I need clean import from ver2.3.x to ver2.4.x？
Or, Is it enough to update with overwrite importing?

Thanks.
