after a lot of research on this forum, I didn't found a correct system to control beamer with PJlink protocol...

http://www.diecyde.com/index.php?page=pjlink-beamer-control

I tuned up it and modifed it to work with " mxj " function 

It is very simple to use it and it's light. 

here is the patch code that work with the java external PJlinkConnect :

Hello,
I'm trying to use this patch without success.
I've installed Java, but when I'm trying to connect to a videoprojector nothing happens. 
Instead I read this message in the console :
"(mxj warning)strange coercion: max numeric (long) forced to symbol."
and 
"Receive-Projector: "PJLINK ERRA""

can anybody tell me which Java package shall I download on my Macbook pro (M1 OS 12.2 Monterey) to run max8? (not for developer). If you also could provide a link would be great!

Hi all, once upon a time I remember being able to find a manual on how to create MXJ externals here. How can I find it these days?

where's-the-manual-on-how-to-write-java-objects

You can find "fresh" documentation here:
https://cycling74.com/sdk/max-sdk-8.0.3/html/modules.html 

I'd be happy to send you the old .pdf which dates from Max4.5, I couldn't find it on cycling74's website.

Thanks! I found it on an old harddisk, so no need to send it.

But this is a bit worrying: is Java in Max perhaps slowly dying?

mxj development has moved to github, and the docs are available here: 
https://github.com/Cycling74/max-mxj/tree/master/java-doc

Where's the manual on how to write Java objects?

I am certain there is any easy answer to this question, however I have been unable to find one online.

I am trying to calculate a division within the JS object, but I would like it to divide as an integer variable normally would and not as a float as it is doing currently. I am using a modulus calculation for dealing with the remainder.

The only type of variable that seems to compile is 'Var' but this does not allow me to specify whether it is an integer or float.

Any help on the correct syntax to declare the variable as an integer would be greatly appreciated!

I'm trying to pass matrix from nurbs with @matrixoutput 2 to mesh inside mxj.

Is it possible?

Hello

Is it possible?
What method should I use?
Can not find a

nurbs-matrixoutput-2-to-mesh-inside-mxj

you have to use a JitterListener object and attach to the nurbs, listening for the "matrixoutput" event. search the file browser for js.gl.matrixoutput for an example in JS (technique should be the same in Java).

Finally I got the matrix from nurbs to mesh. Thanks! (may be matrixoutput example can be also included in mxj examples?)
now trying to catch only vertex planes for mesh, because mesh color matrix should be controlled separately.
but when I set jit.pack offset 0 and jump 3 in mxj,   jit_pack.matrixcalc posts: 1297306704 calling matrixcalc on jit_pack
it seems rather obvious task, but any clue will be appreciated.

well, I played with different matrixes and jit.pack did it's job

In Java, after I've created a jit.movie, with: 

JitterObject movie = new JitterObject("jit.movie");

...I can't query its dimensions. If I'd write:

Querying other attributes is no problem at all, but dims specifically is weird.

Is this the expected behaviour? How do I find out the dimensions of my movie?

In Java, after I've created a jit.movie, with:

how-to-get-dimension-of-jit-movie-in-javamxj

I think the dimensions are an array. So it should be something like: int dims [] = movie.getAttr("dim"); . Also I believe you can also use the function: movie.getDim();

Thanks Timo,
Yes, the dimensions should be an array. When I run the .getAttr("dim") or indeed the .getDim() method on a JitterMatrix, I get the expected result. However, this doesn't work for JitterObject objects within Java.

I'm not entirely sure, but maybe you can do something like this:

JitterMatrix mat = new JitterMatrix();
mat.frommatrix(movie);
int dim[] = mat.getDim();

Thanks, I think somewhere along such lines I could find a solution indeed. Unfortunate though that this involves reading in a movie twice:

once using the JitterMatrix to determine its dimensions.
once using the JitterObject referring to a "jit.movie" to actually play it.

but if this is the only way, I'll use an alternate (equally ugly, but more cpu friendly) solution: scripting the creation of a jit.movie in the parent patcher of my mxj and controlling/querying it through send and receive.

If anyone knows why accessing dimensions in an internal jit.movie is impossible, they're very welcome to enlighten us!

use the "moviedim" attribute. this will give native file dimensions at file load time.

I am new to programming externals in Java, as well as Jython. I am trying to output a string into a message box using Jython. Here is my function. It does not output the string. It will output a number though. Any idea on what I need to do to get it to work?

I am struggling with some Max-Java basics...I am an absolute Java beginner

I would like to get two matrices into Java external and convert them into two arrays. Ideally the matrices should have different dimensions.

I know how to do that for one matrix but with two matrices I am stuck.

PS: what I need to do is to compare individual cells of two matrices

Hi there,
I am struggling with some Max-Java basics...I am an absolute Java beginner
I would like to get two matrices into Java external and

converting-two-jitter-matrices-into-two-java-arrays

I am actually already stuck at just getting two matrices inside Java. For instance this is the code from Jitter tutorial 51:

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

public class j51matrixinfoexample extends MaxObject {

   public void jit_matrix(String s)
   {
     JitterMatrix jm = new JitterMatrix(s);

     outlet(0,"name", jm.getName());
   }
}

How to modify this patch so I could input two matrices (one through inlet 1 and another through inlet 2) ? 

try this (I haven't tested it but I think this is the way to do it):
[edit--made jm0 and jm1 global]

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

JitterMatrix jm0;
JitterMatrix jm1;

public class jtwoMatrixs extends MaxObject
{	
 	// just put another "DataTypes.ALL" argument in the declareInlets 
 	// method for another inlet
	public jtwoMatrixs(Atom[] args)
	{
		declareInlets(new int[]{DataTypes.ALL, DataTypes.ALL}); 
		declareOutlets(new int[]{DataTypes.ALL});		
	}
	
	public void jit_matrix(String s) 
	{
		//check which inlet the matrix came in
		int inlet_num = getInlet();	
		
		//if it came in the first, call it jm0
		if (inlet_num==0)
		{
			jm0 = new JitterMatrix(s); 
		}
		
		// jm1 for second inlet
		if (inlet_num==1)
		{
			 jm1 = new JitterMatrix(s);
		}
	}
	
       public void bang() //bang to see if it works
	{
		outlet(0,"names", jm0.getName( ) +", "+jm1.getName( ));
	}
 }
