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

Hey everyone,

Emerald AI 2.3.1 has been accepted and is now live!

2.3.1 Release Notes
New Features

• Added a brand new example character controller. This is a top-down style similar to Diablo. It features adjustable attack speed, critical hits, various sound effect options, built-in target indicators, and is fully implemented with Emerald AI's new Combat Text System and Camera Shake system.
• Added global Combat Text System which replaces the previous individual combat text system. The new system has been updated to Unity's newer UI system, can be globally controlled with the Combat Text Manager, detects critical hits, AI healing, player damage, and tons more. It also has 5 options for text animation and various settings for controlling speeds, sizes, and colors.
• Added an option for melee AI to have critical hits.
• Added an option to adjust the critical hit odds and damage multiplier for successful melee critical hits.
• Added a Camera Shake system that can be called on using: CameraShake.Instance.ShakeCamera(float ShakeTime, float ShakeAmount); This is useful for critical hits, but can also be used for other custom mechanics. This requires dragging the Camera Shake System prefab into the scene to be used.
• Added various new sound effects, new abilities, and new spell effects.
• Added various font styles to demonstrate the new Combat Text System.

Improvements

• Rewrote the way the single mesh Disable When Off-Screen feature was handled to be more reliable and efficient.
• Added an option to allow AI to be disabled on start. Previously, all AI would be enabled on start until they were culled or not visible by the camera.
• Added an option to control if an AI will attack with its melee attack right when it arrives or wait for its attack speed to calculate an attack (This only happens on the arrival of an attack).

Fixes

• Fixed an issue where non-heat seeking projectiles would hit the base of the player (their feet) instead of the center of their collider.
• Fixed an issue where the damage over time effect spawned incorrectly.
• Fixed an issue where AI would sometimes play a ranged attack animation and not use an ability.
• Fixed an issue where damage was being generated per animation instead of per hit, when using a melee animation with multiple damage hits.
• Fixed an issue where an AI would sometimes fire a projectile in the wrong direction, if the AI's aggro made it switch targets mid attack.
• Fixed an issue that didn't allow the Start Combat Event to trigger if using the First Detected detection type.
• Fixed an issue that allowed impact sounds and hit effects to play after an AI had died.

 

Strange. You can try setting the starting destination of the currently spawned AI right when the AI is spawned using:

Code (CSharp):

1. SpawnedObject.GetComponent<EmeraldAI.EmeraldAISystem>().StartingDestination = SpawnedObject.transform.position;

 

Thanks, I'll look into this and get a fix added with the next update.

 

Hey there, how are you damaging the AI? Are you using the Damage function? An AI will only play a hit animation (if this is the animation you are referring too) if the AI is stationary and not currently attacking.

 

1) This would need to be handled with a simple script that temporarily stops the companion AI from following its follower as the companion's destination is continuously updated to follow its follower. There's an included system that allows an AI to search for "resource" objects, go to the detected object, and play an animation. You could use this system when the above mentioned script stops the companion AI from following its follower.
2) Not currently, but I can look into adding a couple different following types for companion and pet AI with a future update.
3) I do plan on adding a feature for AI to look for cover spots within the next update or two.

 

To clarify, if you do not call SetDestination, the AI will not detect the player or move? This may be how the AI sets its destination within the EmeraldAIInitializer script. When generating dynamic destinations, a raycast is fired downwards from the world up position which would make this unreliable for a spherical word. Custom destinations could be set using a custom script that uses the direction of your spherical world. If you could please post a few screenshots of your generated navmesh in your scene, it would help me get a better understanding of what might be happening.

 

Currently, there are two types of target detection, first detected and the closest detected target. I have plans to add more detection types with the next update such as randomly picking between the currently detected targets.

For now, here's a script that will allow AI to randomly pick from targets within their detection radius when they enter combat. This is triggered using an OnStartCombat event. Simply attach it to the AI you'd like to have their detection type overwritten. There's also a delay variable to allow other targets to get within range so the AI doesn't pick the first detected target.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using EmeraldAI;
5.  
6. public class SwitchToRandomTarget : MonoBehaviour
7. {
8.     public float CallDelay = 1;
9.     EmeraldAISystem EmeraldComponent;
10.     Coroutine RandomTargetCoroutine;
11.  
12.     void Start ()
13.     {
14.         EmeraldComponent = GetComponent<EmeraldAISystem>(); //Get a reference to this AI's Emerald AI Component
15.         EmeraldComponent.OnStartCombatEvent.AddListener(() => StartGetRandomTarget()); //Create an event that triggers when the AI starts combat
16.     }
17.  
18.     void StartGetRandomTarget ()
19.     {
20.         if (RandomTargetCoroutine != null){StopCoroutine(RandomTargetCoroutine);} //Stop the courtine if it's already running
21.         RandomTargetCoroutine = StartCoroutine(GetRandomTarget()); //Start the GetRandomTarget courtine
22.     }
23.  
24.     IEnumerator GetRandomTarget ()
25.     {
26.         yield return new WaitForSeconds(CallDelay); //Delay the call so the first detected object isn't assigned
27.         if (EmeraldComponent.CurrentTarget != null)
28.         {
29.             EmeraldComponent.EmeraldDetectionComponent.SearchForRandomTarget = true; //Enable the SearchForRandomTarget bool which allows the SearchForTarget to look for a random target.
30.             EmeraldComponent.EmeraldDetectionComponent.SearchForTarget();
31.         }
32.     }
33. }

 

Thank you for responding!!
For 1) Do you have any examples that I can follow? What Events do I capture to make this work?

2)Would love to have such an option!! Thank you so much
3) Awesome! You made my day

 

@BHS Roadmap for next update?

 

Casting bars for spells or abilities would be awesome for the AIs

 

low poly fps pack integration would be awesome as well.

 

Low poly fps isnt a controller.... its just animations with a basic mini demo controller.

 

@BHS I checked the latest version and it still has the issue where if I set TotalAttackAnimations to 0 in a script that the AI still randomizes an attack and performs the attack. By being able to set this to 0 in script, but still have attacks in the list, it makes it possible to script phased boss battles and control attacks. It's not a hard hack to fix, but if we can have it in the next version that would be great.

 

Yea I had to do my own little hack for that and I'm still using it. Would be nice to have some native control over that would be nice.

 

Hi, i have a tarantula AI which is firing green slime balls at the player. Sometimes it works, but the most time not. Then i can see the slime ball under the tarantula firing, but its not flying at the player. Having this problem with other ai`s too which are firing other projectiles. Never got ranged attack to work steady. What could be wrong ? Thank you.




I have reduced the size of the box collider, but nothing helped.

 

Are the projectile and enemy layers set to collide in your physics settings?

 

@christougher, where can i find this settings ?

Hi there!
I am trying to make the AI "faint" by using the ragdoll system. How can I call via script?
Thanks in advance!

Dom

 

Hi,
I was trying to follow

to setup my AI but the options I had were less. Why is that? I'm using the latest version 2.3.1.

 

Looks like half f your inspector is off screen. Try docking it to a other side of the screen

 

Thanks!. That's the reason.
But docking it to the other side didn't help. I had to change my resolution but that's not what I want. Everything became so small. Hard to see anything. There is no scrollbar? I've used so many assets. It's the first time like this for me.

 

I doubt you are going to get any quick response here. You should head to Black Horizon Studio's Discord page. They are quite active there
https://discordapp.com/channels/580130304174456842/580138530383331328

 

It might be your Ranged Attack Transform. It may be in a position that's too low which would make it collide with the ground before reaching its target. Try using a different transform that's higher. Did you add any other colliders to your projectiles? This could also be the cause of the issue. A video of the issue would help me better understand what's happening though.

 

I haven't tested enabling the ragdoll components while the AI is still active, but you can try using:

Code (CSharp):

1. YourAI.GetComponent<EmeraldAI.Utility.EmeraldAIInitializer>().EnableRagdoll();

 

What version of Emerald AI are you using? This was fixed a little while back. It's because the pixel difference with 4k monitors.

 

thx for your attention. I downloaded it yesterday and it should be 2.3.1. Where can I see the version?

 

Hi BHS !, can we expect an increased number of animations in the next update?

 

It is, but you have to do some coding. There's only really two pieces you need to modify. I'm using older versions of both packages, but integration is likely similar. If you look in the docs for both packages, you'll see the updated code blocks you need to add.

In for horror, locate the weaponcontroller.cs, in the bulletmark method, you want to add something similar to this:

Code (CSharp):

1.  
2. if (hit.collider.gameObject.GetComponent<EmeraldAI.EmeraldAISystem>() != null)
3.  
4. {
5.  
6. hit.collider.gameObject.GetComponent<EmeraldAI.EmeraldAISystem>().Damage(damage, EmeraldAI.EmeraldAISystem.TargetType.Player, player.transform, 400);
7.  
8. }
9.  

In the emerald package, in emerald_ai.cs, my version has a damageplayer method, you need to add code similar to this:

Code (CSharp):

1.  PlayerGameObject.GetComponent<HealthManager>().ApplyDamage(DamageToPlayer);

The more difficult challenge is actually the save game portion, you have to add an object dictionary to emerald_ai to collect data and then set the data (position, alive or dead, health, etc). Then you have to modify the saveobject.cs from hfps to add emerald as a new savetype. If you need to code, let me know and I can provide you what I have for it, but my versions are older (emerald 2.0 and hfps 1.42). Something to keep in mind is that once you start modifying the packages, you orphan yourself from being able to upgrade without going back and updating your modifications.

 

Thankyou for replying @cloverme. I have sent you a pm.

 

Thanks! I will try and let you know!
thanks again

 

Has anyone integrated opsive ultimate controller?

 

Yes, I wrote integration instructions and they can found on the Opsive Forums:

https://opsive.com/forum/index.php?attachments/opsive_v2_emeraldai_intgration-pdf.1647/

 

how to make a flying ai i wonder?

 

The Asset Store should tell which version you are currently using.

 

Yes, I will be increasing all animation lists to 6 animations and redoing the faction system with the next update.

 

It should wander and generate waypoints using the Dynamic Wander Type.

 

The ability to have NPC sit?

 

Could we get the option to use an event for inflicting damage in a future update? In combat events, currently we can specify a receive damage event (and attack event), it would be great to also use an inflict damage event (or however you wish to word it). So then we could play an animation of the enemy taunting, or make him less aggressive or whatever you want really, many possibilities would be opened up just from that one option.

 

I have a DamageAI action in my Playmaker integration if you are interested in going that route. The integration can be downloaded from the following forum post:

https://forum.unity.com/threads/rel...ality-ai-solution.336521/page-89#post-5132540

 

Thank you, but I have damaging AI working already. I think I should explain it better:
When the AI damages a target (e.g player), then call an event. Currently, we can call an event if the AI attacks or gets damaged itself.

I could find a way around this of course, but it would be a time-saver if implemented.

 

To me, this is better handled by the Player Controller itself since it is the one getting damaged. What controller are you using?

 

@magique I am just using Unity's character controller with Adventure Creator. What I was thinking is, the AI would earn "XP" when it makes contact using it's attack. But, I can no doubt find ways around this if it is never added.

 

Well, in order to damage the player, you have to modify the DamagePlayer script anyway, so you can easily put the code right there to tell some global GameManager class how to handle it.

 

having issue again where my ai wont die log states they are dead but they just slide along any ideas? [RESOLVED]

 

My AI will shoot at the Players feet no matter what I try. I raised the player offset like in the picture below which is represented by the green line (top one), but the AI will ALWAYS fire along the yellow line (bottom line). What do I do?

 

Hi!

I'm trying to get the enemy's ad in a canvas ad. So I don't want to have the health meter above the enemy directly anymore.

Question of mine would be, where can I read out, which target is currently active and how do I get his values from the target for the display?

Hope you can help me further.

Greetings from Kojote

 

@BHS Hello, what is the current state of compatibility with Malbers animal assets? I was hoping to use them with Emerald for the purposes of companion AI and also with Crux Spawner for general fauna.

 

For some reason my ai wont damage each other, they attack but no damage is taken Update (AI will only cause damage to each other if neither are companions, if one is a companion no damage is done to either parties

 

Hi all,

Just wondering, approximately how many AI ingame are supposed to be used before emerald AI starts becoming a real bottleneck? Because I can only get up to ~500 AI before the AI themselves are taking about 10-15ms on the server and for any type of multiplayer game that's supposed to have dynamic AI, this seems pretty low. (500 seems high at first but if you're on an 8kx8k island and spread them over it, you barely encounter one every 10m if you're constantly moving. Also there is other stuff that needs computations as well-not just AI)

Are there any plans to increase performance? I'm looking to have about 1k AI on my land (and it'll increase if the map gets bigger) but this doesn't seem feasible atm.
