Maybe a super-simple-to-solve question but I haven't been able to figure this out!. I am trying to generate a simple java class that triggers a jit.noise every time it gets a bang. I have something like this:

public class matrixTest3 extends MaxObject{

declareOutlets(new int[]{DataTypes.ALL});

noiss=new JitterObject( "jit.noise", new Atom[] { Atom.newAtom( 4 ), Atom.newAtom( "char" ), Atom.newAtom( 100 ), Atom.newAtom( 100 ) } );

dim1=new JitterMatrix("dimen",4,"char",100,100);

outlet(0,"jit_matrix",new Atom[]{Atom.newAtom(dim1.getName())});

So by calling the method generate() i would like to get the random values of the matrix.

Hello!
Maybe a super-simple-to-solve question but I haven't been able to figure this out!. I am trying to generate a simple java class that triggers a jit.noise every time it gets a bang. I have something like this:

import com.cycling74.max.*;
import com.cycling74.jitter.*;

public class matrixTest3 extends MaxObject{
    JitterObject noiss;
    JitterMatrix dim1;

    public matrixTest3(Atom[] args){
        declareInlets(new int[]{DataTypes.ALL});
        declareOutlets(new int[]{DataTypes.ALL});
        noiss=new JitterObject( "jit.noise", new Atom[] { Atom.newAtom( 4 ), Atom.newAtom( "char" ), Atom.newAtom( 100 ), Atom.newAtom( 100 ) } );
        dim1=new JitterMatrix("dimen",4,"char",100,100);
    }

    public void bang(){
        //generate();
        outlet(0,"jit_matrix",new Atom[]{Atom.newAtom(dim1.getName())});
    }

    /*
    public void generate(){
    I am not sure what to put here!
    */
}  

So by calling the method generate() i would like to get the random values of the matrix.
Sorry if the question is too basic!

Jitter generators are just special versions of matrix operators, with no inputs, only outputs. Use the matrixcalc method to generate the output matrix. As mentioned in a previous thread (on jit.noise in Java), in Java, Javascript, or C these objects don't take matrix arguments like their max wrapper counterparts.

noiss=new JitterObject( "jit.noise");
dim1=new JitterMatrix("dimen",4,"char",100,100);
noiss.matrixcalc(null,dim1);

thank you for the fast answer. I modified my code following your advice:

public class matrixTest3 extends MaxObject

dim1=new JitterMatrix("dimen",4,"char",10,100);

it works but i cannot update the state of the matrix every time i send a bang. Is there any way to do so?

I tried a different approach but this didn't work(it compiles properly but doesn't output anything):

public class matrixTest4 extends MaxObject

        dim1.frommatrix(inname);        

        outlet(0, "jit_matrix", dim1.getName());

Hello Joshua:
thank you for the fast answer. I modified my code following your advice:

public class matrixTest3 extends MaxObject
{
    JitterObject noiss;
    JitterMatrix dim1;

    public matrixTest3(Atom[] args){
        declareInlets(new int[]{DataTypes.ALL});
        declareOutlets(new int[]{DataTypes.ALL});
        noiss=new JitterObject( "jit.noise");
        dim1=new JitterMatrix("dimen",4,"char",10,100);
        noiss.matrixcalc(null,dim1);
    }

    public void bang(){
        outlet(0,"jit_matrix",new Atom[]{Atom.newAtom(dim1.getName())});
    }
}

I tried a different approach but this didn't work(it compiles properly but doesn't output anything):
import com.cycling74.max.*;
import com.cycling74.jitter.*;

public class matrixTest4 extends MaxObject
{
    JitterObject noiss;
    JitterMatrix dim1;

    public matrixTest4(Atom[] args){
        declareInlets(new int[]{DataTypes.ALL});
        declareOutlets(new int[]{DataTypes.ALL});
        noiss=new JitterObject( "jit.noise");
        dim1=new JitterMatrix("dimen",4,"char",10,100);
        noiss.matrixcalc(null,dim1);
    }

    public void jit_matrix(String inname)
	{
		dim1.frommatrix(inname);		

		outlet(0, "jit_matrix", dim1.getName());
	}
}

This is quite strange. I recompiled the external and now nothing happens.

#N: extra arguments for message "jit_noise"

This is quite strange. I recompiled the external and now nothing happens.
It is saying:
#N: extra arguments for message "jit_noise"
wow, I am pretty lost here.


- #N: extra arguments for message "jit_noise"

That is assuredly from your old example where you passed in matrix arguments to your jit.noise object. the new examples should not exhibit that behavior.

The noise is calculated by matrixcalc. Call it once per frame as in:

noiss.matrixcalc(null,dim1); // this is what generates noise!

public void bang(){
noiss.matrixcalc(null,dim1); // this is what generates noise!
outlet(0,"jit_matrix",new Atom[]{Atom.newAtom(dim1.getName())});
}


wow, thank you for the help!
Sorry for all the noise!
