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

Is there an integration for uRPG yet?

 

@BHS I have a small suggestion to toss into the hat for upcoming updates. Allowing the user to input their own animator location would be incredibly useful. I've hacked one in on a project I'm working on, but it would have been so much easier to just integrate that into the setup process for those less "programming-capable". In this project the animator is on a "base" component that is an immediate child of the main NPC object.

 

I want to use Emerald AI in a RPG game using a first person player for melee combat. Does Emerald support first person?

 

Your player solution being third or first person is irrelevant. The only requirement is that your player solution can integrate with Emerald and vice versa. Most systems already have integration such as RFPS, but integration is fairly easy even if your chosen player controller doesn't already have it.

 

- Realistic herd mechanics are coming with the 2.4 update, but animals can still wander around with various animations and avoid predators animals.
- I do plan on adding more emote animations after the 2.3 update.
- AI cannot currently swim, but I also plan on adding this at some point. With the example code I posted previously, it is possible for AI to play drinking animations if the collide with the trigger collider. However, the will not seek out said collider. It is only if they happen to come in contact with it.
- Yes, you can place as many waypoints as needed to trigger colliders that can then play needed emote animations using the script I posted. If you setup your factions, you can have certain animals chase and kill other AI. The opposing AI will flee, if you've setup your AI's factions and AI's settings to do so.
- The included character controller is a simple example that allows users to receive damage and inflict damage to AI.
- There's currently no needs system.

 

Not yet. I will begin working on this as soon as the 2.3 update is finished.

 

I can certainly look into this feature for a future update.

 

ah right brilliant how would it be possible to make predators chase prey in radius? or is this a future thing?

 

My Player doesn't seem to be detected as a Player by EmeraldAISystem, but as an AI, though the AI creatures detect the Player and attack it as it's supposed. The Player is tagged Player, and on Player layer. The problem is when the creatures attack, their damage isn't sent to the Player. Apparently EmeraldAISystem consider my player as an AI (TargetTypeRef == TargetType.AI and not .Player, I know because I added a bunch of debug.log ). There's probably something wrong with my Player but I can't find what. What could be causing this?

 

Yes, every AI has its own Detection Radius that it uses to either flee from or attack targets.

 

I did notice something similar while developing the version I'm currently working on and managed to fix it, but it didn't happen very often. I believe the issue was related to the aggro system so try disabling that to see if it resolves the problem for now.

You can also try look at these line in the EmeraldAISystem script as they may be mislabeling your player.

Code (CSharp):

1. TargetTypeRef = (TargetType)TypeOfTarget;

 

ah right so it is possible to create a predator prey relationship ?

 

@BHS Hi, thank you for the answer. I pinpointed the issue with the Line of Sight detection method. With the Trigger one it work as intented, they deliver damage.
In EmeraldAIDetection line 302+ the Player is identified, but after that the TargetType.Player is lost somehow. I'm super beginner at scripting and cannot figure this out :/

Also in Trigger detection mode, once my Player is killed by the AI, they continue to attack as if the Target isn't cleared. Is there some parameter I missed somewhere for that?

Edit: Deactivating the aggro on AIs didn't change the issue.

 

2.3 going to have NPC logic ie at 25% health, cast this spell and do these series of animations?

 

Yes, you would just customize the Faction System. For example, a wolf could be apart of the Predator faction and will see the Prey faction as targets. The Prey faction will see the Predator faction as threats and will flee whenever they enter their detection radius.

 

Are you using a custom character controller? Have you tried testing the included demo scenes to see if this problem is still present?

You also need to make sure that you set your Player layer within the Emerald AI editor as by default the only layer that's detected is the Water:


You need to handle your own logic when the player dies. I've updated the included EmeraldAIPlayerDamage script with the new version to stop AI from attacking once the player's health has reached 0. Since all damage is sent through this script, you just need to apply some code to tell the AI when the player is dead or their health reaches 0, if you are using a custom health system.

 

Yes, the Support abilities will only trigger when the health percentage threshold has been met. The logic for this will be expanded with future versions as well as additional support abilities other than healing.

 

For those who are interested, I've updated the Emerald AI Demo to version 2.3 to showcase some, but not all, of what's possible with the 2.3 version of Emerald AI.

Emerald AI 2.3 Demo (1GB)

 

What an incredible AI system this is, i started out using Emerald Animal AI a while back, and really loved it (still do), but after upgrading to EmeraldAI 2.2, its been great, im developing a jurassic type game called Jurassic Extinction (posted in the WIP section) and i couldnt be happier. I do miss the "grazing" and maybe it will be added in, at a future date.

Its worked out great for dino AI, and the integration with UFPS and Invector 3rd Person Controller, is just great. Ive had no console errors to correct, or any probs so far. Thnx guys, great work on this asset

 

hello, i start coding and i use vrtk with emerald but i only find integrarions ufps or invector, i want to use the system of shooting the gun vrtk simple to damage the AI but i can not find any script ... could you m help for setting up a script? thank you

 

Is their a health system for AI?

 

Well health can be set in a few ways:
You can set base health ( min and max)
You can set at what point a agent "flees" by percentage of health
and can set a health "bar" above an agents body (option)
I wish it had Grazing, and Thirst system that Emerald Animal AI had...
Right now im just getting used to the system, and mods can be made to the code, but base functions are really good

@CHACHINOI you wont find a script for that integration, unless BHS can dev one, thats a tough integration.

 

ah right will the health work for the AI ? and how would i go about implementing the health to the AI?

 

Very cool game! Thanks, it's great to hear you're enjoying Emerald AI and that it's working for your project. I would appreciate if you left a quick review on the Asset Store, if you have the time.

Also, AI can play grazing animations. You just use gazing animations in place of idling animations. I have a few ideas of how to improve this after version 2.3 is released by generating waypoints according to objects such as food sources. This way AI can go to food objects and play eating animations.

 

In order to damage an AI, you just need a reference to the object that was hit with something like this:

Code (CSharp):

1. if (YourTargetReference.GetComponent<EmeraldAI.EmeraldAISystem>() != null)
2. {
3.    YourTargetReference.GetComponent<EmeraldAI.EmeraldAISystem>().Damage(YourDamageAmount, EmeraldAI.EmeraldAISystem.TargetType.Player, YourPlayerTransform, 400);
4. }
5.  

 

Each AI has its own health variable built into the Emerald AI system. Users can set the total health an AI has, as well as how quickly it regenerates after receiving damage, all from within the Emerald AI editor.

 

ah brilliant would an additional collider or a damage script be needed so that it recognizes when it has been hit?

 

@BHS That demo is actually really good.

Anybody on the fence should try out that demo.

 

A collider is applied automatically so there's no need to apply any additional ones. An AI can be damaged by having a reference to the hit AI object and using something like below. This will automatically damage the hit AI according to the YourDamageAmount parameter.

Code (CSharp):

1. YourTargetReference.GetComponent<EmeraldAI.EmeraldAISystem>().Damage(YourDamageAmount, EmeraldAI.EmeraldAISystem.TargetType.Player, YourPlayerTransform, 400);

 

ah brilliant would i need to put this reference in my create damage script?

 

Yes, that is correct.

 

Thanks! I feel like the previous demo did not show Emerald AI's versatility very well. I'm glad you like it.

 

and does the dead animation require anything to work or will it just display the animation once dead?

 

Nope, all you need to do is apply a death animation to the death animation list (you can use up to 3) and one of them will play once your AI's health reaches 0.

 

Any chance that you can add stats to the AIs like mana, stam, armor?

 

Im going to leave a review on asset store for sure. Yes, that what ive done is use grazing animations instead of idle, and it works great, also to be noted is EmeradAI works well with flyers, as it can use any animation, but seems to work really well with my Pteranodons, flying up, dive attacks, etc. they look very realistic.

Great idea with the waypoints/food sources, would be a good addition.

 

I wanted to add these features in with the 2.3 update, but I didn't want it to delay the update any further. I have plans to add these, as optional features, after the 2.3 update.

 

Thanks! That's great to hear Emerald AI has worked so well for you. A really cool improvement with version 2.3 is the significant improvements to AI turning so AI will fully utilize their blend tree turning animations like below, which should look great with your dinosaur models. Cool looking game btw!

 

ah awesome but i do require a damage script or can i just use this asset?

 

Are you referring to player damage or AI damage?

A simple player controller is included that will damage an AI and receive damage from an AI.

If you are using a custom solution for a character controller/player health, you would need to add calls to your custom health system to Emerald AI's EmeraldAIPlayerDamage script. Then, with your custom weapon system, you would add the damage code I posted above to the object that your weapon system hits.

 

That looks awesome!

 

Another question, if i wanted an AI ti stay stationary or can only move in x radius, how would i do that?

 

@BHS Went to integrate with UFPS and got 9 console errors..sent you a conversation request, un less you want me to post here... I even tried the code that was in the tutorial video, as it was different...

 

The Stationary wander type allows an AI to stay in one place and the Dynamic wander type allows the AI to generate random waypoints within its wandering radius. Or do you want the ability for the AI to switch between the two?

 

Yes, I was able to read you message. It looks like there may be syntax errors. Also, what version of UFPS are you using? The tutorial covers version 1.7.5 and not the newer version.

 

ah right no what i'm trying to do atm is have AI animals attack and kill other animals. Also have an AI fight back or flee on low health when being hunted by other AI

 

Hey everyone!

Since there have been numerous request for awhile now with a proper AI's needs/grazing system, I thought I'd write one up real quick, I was also curious of the versatility of Emerald AI.

The AI Needs System will be included with the 2.3 update. For those who want it early, send me a private message via a Conversation, along with your Invoice Number, and I would be more than happy to send it to you early. It should work with the current 2.2 version.

As for the needs system, it works by efficiently searching for nearby objects of the appropriate layer, when an AI's Current Resource amount reaches 0 (aka it's hungry, thirsty, etc). When this happens, an AI will generate waypoints to the detected resource objects, up to the Max Resource Waypoints amount. When an AI reaches a resource object, users can specify which idle animation will be played based off of the index of their Idle Animation List such as an eating animation. The AI will then refill their resources at a rate of 1 resource per second according to the AI's Wait Time seconds.

After an AI has reached its full limit, it will switch to the Dynamic Wander Type and wander around its new area until its Current Resources reaches 0 again. It will then repeat the process, but most likely getting new resource objects with each time it generates new waypoints. There is also an option for an AI to die if it doesn't get to resources quick enough.

Lastly, there is a Gathering Event that is triggered each time an AI successfully collects a resource. This can be used to run custom code to add items to custom inventories or add values to custom variables

I wanted to keep the system very general so any kind of AI can use it. It could allow an AI to collect resources for a town, allow an animal AI to look for food and water sources, and tons more. AI will also still react to or fight off potential threats. All in all, it should allow for some very cool added functionality. I'm looking forward to seeing what users can create with. Keep in mind, I consider it still in beta stage at this point.

Spoiler: Show Editor Screenshot

 

This is handled through the faction system. It's what allows other AI to see who is a target or not. An AI will fight back if they are of the appropriate Behavior Type. For more information on the faction system, see the documentation here: https://docs.google.com/document/d/...2njM7Jx9pYlqgbtM8/edit#heading=h.asmf5b22etw8

An AI will flee when their health is low and if they have the Confidence Type of Brave. You can then customize the amount of health needed for the AI to flee.

 

@BHS I agree, its most likely syntax, and im using UFPS 1.7.5, its looking like its the way i inject the code into the script, any chance i can get a working copy of the EmeraldAIPlayerDamage script? (just send if possible in our Conversation) In the mean time, ill try and figure out whats going on, as this hasnt happened before, could be my Notepad++ which i use for coding, and just updated, could be a few different things, lol

 

@BHS i like that, AI refilling its resources at a generated resource destination, that would be a killer addition, as no other AI i know of does that, and i can think of quite a few applications for that...depending on options...
