Jadex

[yanet]

Hi, I am new in Jadex, and I have a problem, the class BDIAgent is not solve as a type....i look in side the BDIv3 package is there is not BDIAgent class, only BDIAgentFactory, and BDIAgentFeature, Iam following the BDIv3 tutorial on the jadex web, i have jadex 3.0 RC51 installed.........please my english is not so good, forgive my mistakes...

Thanks

Hi yanet,
to implement a BDIv3 Agent, you do not need to extend any type (like "BDIAgent").
Just make sure your class is named "<yourname>BDI" and has the @Agent annotation:</yourname>

@Agent
@Description("The translation agent A1. <br> Empty agent that can be loaded and started.")
public class MyBDI
{

You may also follow this tutorial:
https://download.actoron.com/docs/releases/jadex-3.0.0-RC51/jadex-mkdocs/BDI%20V3%20Tutorial/02%20Starting%20an%20Agent/#exercise-a3-create-first-simple-jadex-agent

If you need access to Agent Features (such as the IBDIAgentFeature), use @AgentFeature to inject them:

@AgentFeature
protected IBDIAgentFeature bdi;

Using this feature, you can work with goals and adopt plans etc.

Hi, thanks , I solve it, but in this link Put in this way
@Agent
protected BDIAgent agent;

@Belief
protected Map<string, string=""> wordtable;</string,>

what it means ??

Hi, I sorry , I have another question

I am following
https://download.actoron.com/docs/releases/latest/jadex-mkdocs/BDI%20V3%20Tutorial/05%20Using%20Goals/
i can´t find
dispatchTopLevelGoal method , I think the problem is that a declare the agent field as Agent of jadex.micro.anotation.Agent, and the cast is wrong in

Translate goal = (Translate)agent.dispatchTopLevelGoal(new Translate(eword)).get();

but I don´t know where I can find the Agent class where the dispatchTopLevelGoal method
belong

please I know my english is veryyyy bad , but help meee

Thanks

Hi??????

[Julian]

The Documentation may be outdated - which is the primary reason, our jadex 3.0.0 releases are marked as "RC" (Release Candidate).
Jadex components are now feature-based, which means, depending on the internal architecture (bdi, micro, bpmn), different "Features" can be injected into agent classes.
The IBDIAgentFeature provides everything necessary for BDI implementation.

The dispatchTopLevelGoal method can then be found in the IBDIAgentFeature:

@AgentFeature
protected IBDIAgentFeature bdi;

...
bdi.dispatchTopLevelGoal(...

Please have some patience regarding the documentation, we are working on it :)

[yanet]

Thanks you !!!!!.....

[yanet]

Hi again, :-).........there is a way for following the ejecution , i mean breakpoint, ????.......

[yanet]

Hi, I would like you help me to understand, how jadex implements, the deliberative behavior of the BDI architecture, I know that Jade is an inference engine, by rules......but jadex????.... I am sorry I am traying to understand .........thanks

[Julian]

Hi,
to quickly answer your questions:
The Jadex Control Center (JCC) includes a Debugger to follow BDI execution: https://download.actoron.com/docs/releases/jadex-3.0.0-RC51/jadex-mkdocs/AC%20Tool%20Guide/12%20Debugger/

If you are interested in details about the BDI architecture, you may want to read this:
https://download.actoron.com/docs/releases/jadex-3.0.0-RC51/jadex-mkdocs/BDI%20User%20Guide/02%20Concepts/

If you have more specific questions, feel free to ask again.

Hi, it was very helpul the links......but I can´t find the debugger in jadex 3.00, I leave you an attachments.

[Lars Braubach]

The debugger is a plugin that can be activated on the top right (not shown in your screenshot). It is the button with a gear wheel on it. Best Lars

[yanet]

Sorry there is something wrong in agnet body

public void body()
{
String eword = "ojo";

 Translate goal = (Translate)agent.dispatchTopLevelGoal(new Translate (eword)).get();
  System.out.println("Translated: "+ eword +" "+ goal.getGWord());
}

but don´t work neither

[yanet]

The 86 line is
Translate goal = (Translate)agent.dispatchTopLevelGoal(new Translate (eword)).get();

[Lars Braubach]

Because you forgot the @AgentFeature annotation necessary for dependecy injection:

IBDIAgentFeature agent;

->

@AgentFeature
IBDIAgentFeature agent;

You can use also the normal Java debugger with Jadex.

Lars

hello, thanks , you are very patience with me....thanks again

Hi, I have another question
If i have a belief who has a @Plan(trigger=@Trigger(factchangeds="sana")) and I have a mantain goal which change de same belife for keeping always in true, which one is the firts in execute?

I mean it is posible??

@Goal(excludemode=ExcludeMode.Never)
class VivirGoal{
@GoalMaintainCondition(beliefs="sana")
protected boolean maintain()
{
return sana=true;
}

      @GoalTargetCondition(beliefs="sana")
      protected boolean target()
      {
        return sana=false;
      }
}

public void Verif(){

        do something
