General Board / Build an exectuable state machine with Visual Studio

« on: May 16, 2022, 10:43:39 pm »

Hej everyone

I am using the model from the EA examples called Entering A State.

It is a class with a state machine attached to the class.

There is also a executable statemachine artifact to build the model.

I am using Visual Studio 2019 to build the model.

I have written the following script (batch) on the execution analyzer.

call "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\VC\Auxiliary\Build\vcvarsall.bat" x86
if not exist SimulationOutput mkdir SimulationOutput
 
cl.exe /Od /Zi /EHsc /Fo".\SimulationOutput/" /Fd".\SimulationOutput/" *.cpp /link /out:".\SimulationOutput\Artifact1.exe"

I do not get any errors when I am building the application.

Although nothing is generated inside the path folder.

Any ideas why ?

Thanks

Bugs and Issues / Simulation of State Machine with JavaScript - is not a function error

« on: November 12, 2021, 09:08:49 pm »

Hi gents

I am trying to simulate an executable state machine with java script.

The java script code that I want to simulate with EA is the following

class Operation {
 
  // Method
  Add(a,b) {
    this.a = a;
    this.b = b;
    return this.a + this.b;
  }
 
}

 // Create object
 operation1 = new Operation;

result=operation1.Add(10,10)

console.log("Addition is " + result);

For the equivalent response from the EA I did the following steps:
1. Define a Class called Operation.
2. Define an operation called Add(int, int) with the following code on the behavior
this.a=a;
this.b=b;
return a+b;
3. I drag and drop the Class as an object into the state machine and call the object as operation1:Operation
4. I create a simple state machine and call the operation on the entry of the state machine but as well as on a transition connector (code added on the effect tab)
I have used the following code variations
sim.result=sim.operation1.Add(10,10)
sim.result=sim.operation1.Add()
sim.Add(10,10)
this.Add()
etc...

The initialization of the variables a and b have been done with different ways, on the object, on the state machine on the execution analyzer script etc.

I am always get the same error : sim.Add is not a function.

Any ideas why ?

Is it a simulation configuration error ?

I can see on the local variables that the Add() function is not called and not even existed on the object.

Any help appreciated 

Thank you

Bugs and Issues / Executable State Machine -Interpreted Simulation returns error ''not a function'

« on: November 08, 2021, 09:03:58 pm »

Hi everyone

I am trying to simulate an executable state machine that calls an operation. The operation returns a value and it is defined on a class.

As a first step I have used the EA example CD Player.

By running the simulation on interpreted mode I got the following error

\\sim.next is not a function.\\ The simulation is running on java.

The same error I got on my simulation.

I have followed all the guidelines described on EA dynamic simulation guidelines.

Did anyone faced the same problems with dynamic simulation ?

Regarding technicalities
1. How EA defines an operation on a class ?
for example if I define the following
this.a=a
this.b=b
return a+b

Is this enough or I have to define a method based on Java ? Define public or state keywords for the method definition etc

2. How I call this operation from a class ?
I have to define an object or just a simple call will do the job ? For example this.result=add(1,2)

Any help appreciated
