Number box like Pure Data

Nailed it.

Made a number box like Pure Data but it still needs some work, any suggestions?

Can you please elaborate?

What is a number box?

This is a PD number box:

Yes, I think it is easy to convert. I’m using the frameCount to count. So if I do counter + 0.1, rather than counter++ I’ll get floating point.

I was asking for ideas to make it better, thank you anyway

Oh, you are commenting other comment, sorry

Congratulations – great work! Thanks for sharing this.

You might also be interested in the numberbox implementation in ControlP5.

import controlP5.*;
ControlP5 cp5;
float numberbox;  // updated by corresponding control name "numberbox"

void setup() {
  size(256, 256);
  cp5 = new ControlP5(this);
  cp5.addNumberbox("numberbox")
    .setPosition(width/2-50, height/2-10)
    .setSize(100, 20)
    .setRange(0, 256)
    .setDirection(Controller.VERTICAL)  // mouse input
    .setMultiplier(1.0)  // units changed per mouse pixel moved
    .setValue(128)
    ;
}

void draw() {
  background(numberbox);
}

For the full documentation, see the ControlP5numberbox example sketch and/or the reference page: http://www.sojamo.de/libraries/controlP5/reference/controlP5/Numberbox.html

That version does not accept text input. There is an example sketch which does:

experimental/ControlP5editableNumberbox.pde

It is a bit touchy, as it deactivates input mode any time the mouse leaves the box screen area, which to my mind is a bit counterintuitive. You could try to remove and replace the .onLeave callback, but I’m not sure if ControlP5 has an easy way to deactivate on click-outside; after looking around I suspect perhaps not.

If you are moving on with your own solution, I would suggest perhaps try a class-based approach next? That will make it easier to create many numboxes and interact with each one separately.

Here is a minimal example with two number boxes. It doesn’t have keyboard input support, although that could be added…

That’s beautiful. Thank you.

I’m new at classes but it seems clean, I’ll look deeper.
