Edit: TLDR:

How do I bind the plug method to a method of an object? Something like:

Code:

Foo f = new Foo();
midiIO.plug(foo, "noteOn", 0, 0);

class Foo {

   void noteOn(Note note){
	println("note received");
   }
}

Hi guys - long time listener, first time caller:

I'm having some trouble with the plug method of the proMidi 2.0 library. I am trying to plug a method of a class "Ship" to receive noteOn messages, but I keep getting the "Error on plug: >noteOn< You can only plug methods that have a MidiEvent, a Note, a Controller or a ProgramChange as Parameter"-exception. I understand the exception, but I don't understand why - the callback-method does have a Note as a parameter...

Some code:

stjernetur.pde-snippet:
Code:

import promidi.*;

Engine engine;

void setup(){
  randomSeed(1337);
  frameRate(30);
  colorMode(HSB);  
  
  engine = new Engine();
  
  engine.setupRenderer();
  
  engine.addHunter(300, 1200, 400, 800, 1, 1);

  engine.bindMidiToShip(0, 1);

}

 

Engine.pde-snippet:
Code:

class Engine {
  MidiIO midiIO;
  ArrayList ships;  

  Engine(){    
    midiIO = MidiIO.getInstance();
    
    ships = new ArrayList();
  }

  void addHunter(int xPos, int yPos, int xGoal, int yGoal, int direction, int midiChannel){
    Hunter h = new Hunter(xPos, yPos, xGoal, yGoal, direction, midiChannel);
    ships.add(h);
  }

  void bindMidiToShip(int shipId, int midiChannel){
    midiIO.plug((Ship) ships.get(shipId), "noteOn", 0, midiChannel);
  }

}
 

The "Hunter" is a subclass of the "Ship"-class, which I want instances of to be the callback objects for the proMidi-plug method. The callback function looks like this:

Ship.pde-snippet:
Code:

class Ship {

  //Code removed
  
  public void noteOn(Note note){
    println("note on " + note.getPitch());
    int notePitch = constrain(note.getPitch(), 0, 255);
    shoot(color(notePitch, 200, 200));
  }
}

 

So, to clarify, I have a "Ship"-class with the subclass "Hunter". I also have an "Engine"-class which produces and stores "Hunter"-instances in a ArrayList.
With a call of the "bindMidiToShip"-method I want to make a "Hunter"-instance the callback object of the plug-method, but I keep getting the "You can only plug methods that have a MidiEvent, a Note, a Controller or a ProgramChange as Parameter"-exception, even though the method specified has a Note type as a parameter.

I am probably just confused on the subjects of callback-objects and method, but I can't seem to wrap my head where the error is.

Please let me know if I should post more code.
