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

Is LifeLink Stop function is more than like stop everything except recevie damage or trigger some animation？It will be so cool~

 

Like hit animations, is will over than six in the future?

 

It stops the AI in such a way so that LifeLink can be in control. However, if the AI takes damage then it stops doing LifeLink things and lets EmeraldAI control it to do battle. Then it resumes LifeLink tasks afterwards.

You can see this in action in the following demo video:

 

I have added sounds to the Attack Sounds section but when the AI is attacking the sounds do not play. Is there any reasons for this?

 

You need a PlayAttackSound animation event on all your attack animations in order to hear the sound.

 

Gotcha, I added the death sounds and they worked without the event. I didn't realize that it needed the event to play the attack sounds. Thank you for that helpful info.

 

Very Cool

 

cool~ I want it to combine with love & hate, it will let npc more like human than before

 

I plan on bringing this back after the next update which will be version 2.6.

 

Have you tried using the Debug Tools (https://github.com/Black-Horizon-Studios/Emerald-AI/wiki/Enabling-an-AI's-Debug-Tools) and enabling raycats to see where the AI's raycast is hitting your player? This is only visible within the Editor tab. Does your player's collider change size?

 

Hello,

Did you added Astar A* pathfinding or still not yet ?, we have terrains that load at runtime (200 tiles) and we are using Astar for dynamic navmesh.

 

Hi, BHS,
There is a critical flaw in Unity's NavMesh system and I have to use Pathfinding Project.
I suppose it's been request few times and I was wondering if you have plan to support it soon.
Right now, I'm jugi going to make a quick patch but I would like an official version..
I would appreciate if you do.
Thanks.

 

What is the critical flaw that you are referring to?

 

Hi, here is the setup.

A middle object, the orange color is a tall ledge and normal NavMesh generator will not generate a path, thus I excluded it from the path generation and there is a hidden NaveMesh underneath it so that NavMeshAgent can move through it. The expected behavior is that the agent will stay on top of the ledge while it's moving through the ledge, but the NavMeshAgent will always put the agent directly on top of the NavMesh, therefore it will go through the ledge object (it ignores the collision between the agent and ledge object).

Pathfinder Project, however, it will put the agent on top of the ledge while going through(it respects the collision between the agent and the ledge object)

 

That's not a flaw. It's doing exactly what you told it to. You need to understand navmeshes better and set yours up so that the ledge is also navigable and that an agent can go from the lower mesh to the higher one. That is all possible, but you need to set it up correctly with off mesh links and jump and drop heights.

 

I know it's possible to jump up the ledge using the mesh link but it involves too much manual work.
Another flaw is that when NavMeshAgent cannot find path, it just sits whereas Pathfindng Project is trying to move toward to the target as far as it can.

Anyway, having the Pathfinding Project integrated would be a good thing. It's much easier to work with it.

 

Well, you said it was a critical flaw. Not wanting to do the manual work to get it working is a different thing.

 

Didn't say it was a bug. Forcing navagent to have a direct contract to navmesh is a critical flaw to me. The mesh link is not even part of the standard navmesh component and it's an overkill and a kludge for what I need to do.

Using Pathfinding Project, you don't need a special setup, you just need to add some animation when moving up/down the ledge. It works beautifuly in my setup.

 

Yeah, I'm all for better solutions. But EmeraldAI only uses NavMesh so far so not really much you can do.

 

@BHS I hope you are well. Where is the documentation regarding EmeraldAIObjectPool.cs?
It was my understanding that EmeraldAI supported object pooling for spawning. How do I use this script?

Thanks.
Mark

 

In my opinion, NavMesh should be optional. AI needs to move toward the target without NavMesh. Currently, AI is useless if it can't find the path. For instance, when a player jumps up a ledge or whereever there is no NavMesh and the AI will just sit and idle instead of moving toward the players. This is one of the other reasons I needed Pathfinding Project.

Yeah, it took me an hour to integrate Pathfinding Project and it works. What you need to do is to abstract the interface. I'm sure you can figure it out without taking too much of your time, unless of course if it's on your todo list. ^^

 

will this asset work with final ik quadground fitter?

 

I've used EmeraldAI with FinalIK grounder and it works great.

[EDIT]
here is a video example of it.

 

@magique Me too, final ik grounded working just fine for me. @BHS has a script to disable final ik as a death event too.

 

Yeah, you definitely have to disable on death. I have a disable behaviors on death feature in LifeLink that I am using.

 

Getting an issue with an AI Generic Rig walking animation - it keeps resetting after the animation is complete. As in, he will complete the walking animation, then teleport back to where he was at the start of the walk animation to start it again - the animation is set to loop, and Root Motion is being used.

Edit: I also can't get emotes to play on this guy.

 

Okay, I fixed the walking issue - it was related to specifying the root node on the character import, this is always a nightmare for me in Unity haha.

Anyway, I still can't get Emotes to play on this character. I am trying to call the play emote event through the event manager, which works on my other characters, but not this guy for some reason.

 

I'm planning on delving into Emerald more next week. Is there an AI heal another AI option? I could only see EventsManager.InstantlyRefillAIHeath(); - looking to seek out nearest AI to damaged AI, then walk up to that AI and heal it.

 

HI~ magique~ Has a tutorial video about how to combine A* Pathfinding Project and root motion ? I watched the tutorial about Final Ik , it works very well for me.

 

Are you asking if I have such a tutorial? I do not. I never used A* pathfinding before.

 

Thanks reply.~Alright~~ I will try it by myself~

 

Hi, is there a roadmap for EmeraldAI? I'll appreciate if you can share it if you have. It will help with planning. Thanks.

 

No, A* pathfinding support hasn't been added yet.

 

I'm not sure if it will help, but Unity does have a runtime navmesh extension that may help: https://learn.unity.com/tutorial/5c515372edbc2a002069505f#5c7f8528edbc2a002053b491

 

Hey there, I made a section on Emerald AI's documentation to cover using the object pooling system: https://github.com/Black-Horizon-Studios/Emerald-AI/wiki/Using-Emerald-AI's-Built-in-Object-Pool

 

Emotes only work when an AI is not in combat. How are you trying to trigger an emote? Are you using this API? https://github.com/Black-Horizon-Studios/Emerald-AI/wiki/Emerald-AI-API#animation-api

 

Not currently, but I do have plans to be able to have AI heal nearby Friendly AI. This will be done through additional options within an Ability's settings.

 

Yes, though I got around this and made it play by calling the animation directly. However, do you think this limitation could be lifted in a future update?

 

Hi

Regarding waypoints, could you add a feature to the AI that it would collect waypoint objects marked by layers and tags? I'm using Dungen to generate dungeons and Dungen uses room based approach to generate. I can place waypoints into the room prefabs but I'd need AI to collect them.

 

That would be a good feature addition. Thanks.

 

my ai companions will follow me into the water but wont follow me out that just stay in the same spot swimming any ideas what could be causing this?

 

Hello,

I have a few questions that I haven't been able to figure out. How do you disable the Emerald AI collider on death so that the player can pass through it? Also i've been trying to set up a kill zone for ai but I can never get it working. Is there a way to damage ai that collide with a trigger?

 

You can add a function to use on the Death Event, something like this...
change LAYER_NUMBER to a new layer that doesn't interact with the Player Layer

Code (CSharp):

1.  
2. public void Awake()
3.     {EmeraldAI.DeathEvent.AddListener(DeadEvent);}

Code (CSharp):

1.  
2. public void DeadEvent()
3.     {EmeraldAI.AICollider.gameObject.layer = LAYER_NUMBER;}

or disable the Collider

Code (CSharp):

1.  
2. public void DeadEvent()
3.     {EmeraldAI.AICollider.enabled = false;}

 

Thank you for the information would you also know how to send damage to an ai when it touches a collider?

 

Try This

Code (CSharp):

1. public int Damage = 5;
2.     public float DelayNextDamage = 2.5f;
3.     protected float LastDelay;
4.  
5.  
6.     protected void Start()
7.     {
8.         //Cache Delay Time
9.         LastDelay = DelayNextDamage;
10.     }
11.  
12.     protected void OnTriggerStay(Collider col)
13.     {
14.         //Don't Damage if Ai is Dead!
15.         if (col.gameObject.GetComponent<EmeraldAI.EmeraldAISystem>().IsDead)
16.             return;
17.  
18.         //Delay Next Damage
19.         if (col.gameObject.GetComponent<EmeraldAI.EmeraldAISystem>())
20.         {
21.             LastDelay -= Time.deltaTime;
22.             if (LastDelay <= 0f)
23.             {
24.                 col.gameObject.GetComponent<EmeraldAI.EmeraldAISystem>().Damage(Damage);
25.                 LastDelay = DelayNextDamage;
26.             }
27.         }
28.     }

 

Thank you yet again for your help

 

Just getting started with Emerald. I'm following the tutorial and I'm stuck trying to figure out where to find the AI Faction Relations screen. I've set up the various factions I want, but the only thing I see under Detection & Tags/Tag & Faction Options/AI Faction Relations is a button to Open Faction Manager. Below that I see a header that says:

AI Faction Relations
List is Empty

I don't see any options to add to the list. What am I missing?

 

anyway to allow ai companions to wander around instead of staying next to the player?

 

It is a little tricky at first, but you were in the right place.
Look under
Detection & Tags
Tag & Faction Option
Faction Options
scroll down to bottom under Player Relations and you will see
AI Faction Relations
click on '+' sign and it will pop up with the drop down menus.

A piece of cake
Good luck!

 

So here's the screen that I see. As you'll note, the AI Faction Relations shows no + to add to the list. In fact, this entire page seems to run off the right side of the screen, whether maximized or minimized. Other pages show the same thing, but some pages, for example the Items tab under AI Settings does show a + where you can add to the Item Object list.

I wonder if this log note when I reopened my project today may be related. It reads:

Code (csharp):

1. The editor layout could not be fully loaded, this can happen when the layout contains EditorWindows not available in this project UnityEditor.WindowLayout:LoadDefaultWindowPreferences()

This apparently has been observed by others for several years. It is currently listed in the Unity Issue tracker for 2020 versions of Unity. [https://issuetracker.unity3d.com/is...d-message-is-shown-when-the-project-is-opened]

FWIW, I'm using 2019.3.7f1. I have reset my layout using Window/Layouts/Revert Factory Settings, but that didn't fix the problem. I've tried some other suggestions discovered via the Google, but no luck there either. Fortunately, I've got time and plenty of other work to do on my project.

EDIT: Update, I found it. But I had to squeeze the Inspector window to it's minimum size and the + showed up. If I widen the Inspector window the + falls out of the right side of the screen and disappears again. The same behavior can be see in the AI Settings/Combat/Damage Settings page.
