ICode (AI For Mecanim 2.0)

There was a problem with some example links in the new update, so i just wrote a small hot fix package for this. Please follow the instructions here.

 

Did an update and all the in Unity example scenes are gone. Any way I can still get acess to them?

Thanks.

 

Yoo, whenever I add the system to my project, I get this error:



"error CS0101: The namespace `global::' already contains a definition for 'AIRuntimeController'"

This happened in two projects, and didn't happen before the update. Any ideas?

 

Hi, please delete the AI System folder before importing the new version.

 

Hi, Zerano
I updated to 1.3, now I have this error in all my previous controllers...
.

 

Hi, you should reimport the examples. http://zerano-unity3d.com/Forums/thread-15.html

 

ok, I installed the examples, but they have new controllers.
I've been working in my own controllers starting from your 1.2 version
it’s mean, if I want use the 1.3 version I lose all my previous work?

 

Hi Zerrano,

Started getting a new error this morning:

The same field name is serialized multiple names in the class or it's parent class. This is not supported: Base(Follow) applyRootMotion

Get the same error twice more but replace the "applRootMotion" for "animator" and "agent".

Anyway I noticed there was an update and tried to download it to see if it fixed the error, it downloaded suspiciously fast. When it came to the import screen there was only 1 line (....\SetInteger,cs), I then tried the Update Manager within unity and it did slightly better with 3 lines (SetInteger.cs, GetProjectedVelocty.cs and UpdateManager.cs).

Any idea what's causing this or is there another link I can try for the new update?

Thanks

 

If I search in files for this project in monodev and look for applyRootMotion I get a few things back. I've deleted all non essential files (like samples that include that var and got it down to 2 files.

Movement.cs and Simple.cs

They do both serialize applyRootMotion, animator and agent. Movement inherits from Simple and Simple inherits from State.They are both stored in Scripts/States/NavMeshAgents

If doubling up on serialization is not allowed according to Unity then the best guess I have is that the, frankly bizarre, update issues I'm having have somehow left me with files from 2 different versions, but that's only a guess.

 

There is only one Simple state now, best way is to just delete the AI System folder and import the new version.

 

Hi Zerano,

Something very strange happening, I deleted the package completely (I deleted C:\Users\Me\AppData\Roaming\Unity\Asset Store\Zerano and removed it from the project I'm currently using) then downloaded it directly from unity, I didn't use the downloaded button I just searched Unity Asset Store for AI and downloaded it directly. The only thing it installed was the scripts folder.

The console is now just saying Assets/AI System/Editor/Update/CheckForUpdates.cs(37,65): error CS0103:The name 'Update Manager' does not exist in the current context.

Currently completely unable to use AI or my project at the moment.

Can't understand how this is happening.

 

Do you have any other scripts then the AI system in your project.(Another class called UpdateManager)?
Can you try to import this package and let me know if the error still exitst:

UpdateManager.unitypackage

 

Thanks Zerano,

Don't know what was causing it but I just created a new project and imported the AI System and Ratkin Army only and it looks like it's working, I think what made me panic is the original download had all the examples included so it took up a few hundred Mb, when I downloaded the latest it only has the scripts and only takes up a few hundred Kb. Sent me into panic mode as it then got the error as well.

If I track down the asset that caused the conflict I'll update in case it helps anyone else.

 

Yes i removed the assets, so you do not need to download them if you only use the ai system without the examples and integrated a donwload manager for the examples.

 

Hey,

I'm doing and enjoying quite well with AI System.

It's good and works fine at the moment, even I extended and modified it for my personal purpose to support legacy animation system with some other various actions.

I'm afraid that there may be duplicated or redundant work which will be at the future release of AI System.

So, it would be good if you share the road-map of AI System, if you have any.

And what's the next update will be?


Best,

-Kim

 

Hey i do not have a real roadmap, what i would like todo in the future is to create more examples and i am sure with new examples there will be new actions, states and conditions.(2D, 2,5D, rigidbody based examples...)

 

I'm interesting in your TDS Prototype

Are you going to Release it? Did you use a Mecanim AI?

And I look forward to the demo RTS Battle

 

The TDS Prototype was created earlier and the ai is hardcoded, but you can create the same ai(or even better) with the AI For Mecanim asset. I can not release it because i simply do not have the art assets to make an example.

 

UFPS Example - the Robot AI Controller appears to be missing. The MineBot is fine. Could you please update the example. I'd really like to learn from this.

 

Sorry the Robot AI Controller was taken from the IK Examples and used in UFPS. So if you import the IK Examples you should have it.

 

The Robot AI doesn't seem to do any damage. I see that the minebot just spawns an explosion. I thought it would be doing some Melee Damage. Do you have examples with the damage as well (preferably both ranged and melee).

 

I have a video showing how to create ranged and meele damage in UFPS:

 

Cool, thanks! Appreciate the extra videos. I thought I was missing something in the examples you provided.

 

Is there any way to get access State.owner or BaseCondition.owner instance in the StateInspector class?

State.owner member field is non-serialized object, so it is always null in a editor script.

How can I get to access the gameObject of current selected state in a editor script such as StateInspector class?


-Kim

 

It is not possible, the system/AIController was made to work in diffrent scenes, so you can not access scene objects in editor mode.

 

Hi Zerano.
I have a question, when in a state of AI controller, i add an IEnumeration, when this IEnumeration ends but the state machine is still in that state, the IEnumeration don't start again right? Because i have a problem with my zombie, when he attack, he play a lot of time the sound effect of attack.

 

Do you marked the action as queue and added a WaitForSeconds action? If the queue is finished it will restart it again.

 

Hi Zerano,
when I start Unity and I'm not connect to internet your chek for update component correctly fails, but it fills of errors my console:
You are trying to load data from a www stream which had the following error when downloading.
Could not resolve host: zerano-unity3d.com; Host not found
UnityEngine.WWW:get_text()
<Run>c__AnonStorey7:<>m__1D() (at Assets/AI System/Scripts/Editor/Update/CheckForUpdates.cs:32)
ContinuationManager:Update() (at Assets/AI System/Scripts/Editor/Examples/ContinuationManager.cs:34)
UnityEditor.EditorApplication:Internal_CallUpdateFunctions()

Is it possible to handle this Exception without throwing those errors?
Thank you

Edited: I read now your request for using your support forum, I will use it for next questions, sorry.

 

Yes going to fix this.

 

Can you tell me or at some point do a tutorial on how to trigger events to send messages back to game objects? That is assuming you can do that with your plug in

 

Hi Zerano,


Regarding line of sight, I was wondering if its currently possible for the character to hide behind a gameobject with a collider. I thought I had this working before, but I can't seem to recreate it.

cheers

 

Version 1.3 is still in beta?
Would have an approximate date when the final version come out?

 

Guys Zerano is still out with a death in his family. He should be back soon though.

 

Sorry to hear that, I was wondering why I hadn't heard back from him. I am in no big rush so I will wait for his return.

 

Hi,
would this AI works good with a Photon?

 

You can use SendMessage action to send a message to the owner or a gameobject that you have assigned before to a parameter. This is realy not that hard. Just use the SendMessage action with a custom parameter or without. To send a message with a parameter use the parameter type to define the parameter you want to send.

Yes this is possible of course, you have to define the correct layer mask in the LineOfSight condition. Just remove the enemies layer and use the equals field to check if the enemy hit something.

It will still take some time. The earliest time when it goes out of beta will be, when i have integrated it with the rpg kit and made more tests and bugfixes.

The ai will not work out of the box with photon.

 

I would really like to see how you would implement a ladder for the AI to go up and down, and a jump zone for the ladder to jump over a gap using your system and Astar pathfinding. I see you have a cool example using 2D for jumping over the gap. I'd really like to have an example for 3D. I tried for many hours to make your 2D work in 3D with Astar pathfinding, but couldn't.

End goal - have AI chase player up a ladder because it's the shortest route. Have AI jump over a defined gap because the player does that.

 

Well it is possible with the build in NavMesh, but i still need to make something similiar for the AStar package.

 

Could you explain how or make an example please.

 

Well for the NavMesh you just create regular OffMeshLinks, which works only on unity pro as far as i know. For the AStar project i would still need to make this integration.

 

What's the intended use case for the Animator CrossFade action? I could have something set up incorrectly, but it seems to me that it's starting the cross fade every frame, which has the effect of sticking to the first frame.

The documentation doesn't really tell me anything, and I downloaded one of the examples but it doesn't seem to use the CrossFade action. Any pointers?

Edit: I just made another AI state system that just has two states with crossfades and they work as expected. So my guess is that I've got the transition happening each frame somehow.

 

Actually, there's definitely something odd going on...

Cross fades with duration set to 0 work fine, in that the correct animation state gets set. Cross fades with durations greater than 0 cause animation to stop. Not sure where the issue is.

 

Thanks, i will test it. However the next update is almost finished and will change the worklfow a little bit. I removed the queue option from the actions, because it was making to many bugs and strange behaviuor, however it will be still possible to make the same timed execution using states and everyFrame option in the actions.
The new update will contain
- clean execution of states and actions
- tooltips for the action and condition fields
- you will not need to drag the AIRuntimeController script on the game object, just drag the new called "StateMachine" asset(AIController renamed to StateMachine)
- Predefined StateMachines that you can just drag into the working editor window and it will place the states, paramerer... into the working StateMachine.(So no need to create same states for diffrent StateMachines)
- Global and local(action fields, condition fields) parameters will be clean (Not more defined by a string and attribute)
- Easy to extend actions and conditions.
- You can use it not just for the ai but also for other things like character control, rts unit control, game control. So it is not longer only an AI System, but still more focused on that.
-ObjectParameter for diffrent kinds of assets(AudioClips, GameObject, Transform,Materials...)
-Conditions for all global parameters
....

 

I bought the package. But there are no example scenes. I don't understand what I have to do to make my enemy behave like in the demo.
Where are the example scenes from the description?

Thank you.

 

I just sended you the link with examples.

 

Can i get the links with examples ? Thanks

NB:
I use an old AI_System_1_1b . When i update it with AI_System_1_3_2b , i have this error message:

 

Please delete the AI System folder and then import the update.

 

Will this break the custom actions/states/conditions I've already made?

I did notice that the guts of your state machine architecture is incredibly similar to what I've written for my character control system.

On another note, I imported the updated package and have run into an issue where I can't open the AI Controller editor any more. The AIs are still working, I just can't open/modify them.

 

Yeah, actually, I can't open the AI editor any more at all. It's not just my existing assets I can't open, even if I create a new one and double-click it immediately I can't do anything.

No errors are logged. Quite simply nothing happens.

Edit: Crisis averted. No idea what it was, but it wasn't your plugin. I noticed that I also couldn't open some other windows, either. I think that what happened is that when Unity hit an error on load earlier today and asked me to reset the layout, it somehow still thought all the old windows were open, so it wouldn't open them again. Loading a new layout again seems to have got everything going again.

 

I am very sorry but yes, this will break all actions, states and conditions you have made, but it will be very easy to convert the states into actions and the conditions have a similiar structure. There will be no longer multiple states, but you will be able to write state code as actions.
