Hi there,

I've seen that the default control label font (a slider label for example) is different from the default Textlabel font.
How can I use the default control label font with my Textlabels?

Thks in advance!

Hi there!

In ControlP5 I want to link two sliders. That is, when I move the slider A, the slider B moves too. And when I move the slider B, the slider A moves too. They must have the always the same value.

The sliders are inside a class. I was not sure about the following code (maybe it creates a loop), but it seems that it works correctly:

1. import controlP5.*;
   
   ControlP5 cp5;
   ControlA ctrlA;
   ControlB ctrlB;
   
   void setup() {
     size(300, 300);
     cp5 = new ControlP5(this);
     ctrlA = new ControlA();
     ctrlB = new ControlB();
   }
   
   void draw() {
   }
   
   class ControlA {
   
     ControlA() {
       cp5.addSlider("SliderA", 0, 1, 0, 10, 10, 50, 10);
     }
   }
   
   class ControlB {
   
     ControlB() {
       cp5.addSlider("SliderB", 0, 1, 0, 10, 30, 50, 10);
     }
   }
   
   void controlEvent(ControlEvent theEvent) {
     if (theEvent.isFrom("SliderA")) {
       cp5.get(Slider.class, "SliderB").setValue(theEvent.getValue());
     }
   
     if (theEvent.isFrom("SliderB")) {
       cp5.get(Slider.class, "SliderA").setValue(theEvent.getValue());
     }
   }
   

Hi!

I want to make a slider with CP5 and I want to control their values with a "snap".
I mean, if the snap = 2, the slider values must be 0, 2, 4, 6. If the sanp = 3, then 0, 3, 6.
Teorically, that's not very difficult using functions like setNumberOfTickMarks(), setTickMarkLength(), snapToTickMarks(), setRange(),...
But it makes me an error when I try to use one of these funcitions, like

cp5.getController("mySlider"). setNumberOfTickMarks(4);

it always says... "The function setNumberOfTickMarks(int) does not exist".
But it exists...

Well, any help would be more than welcome!!

Thanks!

Hi there,

Maybe someone here knows the best way to make that...
I want to control 16 variables with 16 CP5 sliders.

I've the array
int[] values = new int[16]

And now, I want to create an "array of controls", something like that (of course that doesn't work, but that's the idea)

for (int i=0; i<16; i++) {
      cp5.addSlider("values["+i+"]");
      ...
}

And yes, I can create 16 variables and 16 sliders and all would work fine, but I'm looking for the more elegant solution.

Thanks!

Hi,

I'm trying to draw a line...
I want a black, 1 pixel line in P3D. For example, with that simple code I get...a 2 pixel and gray line!!!!

void setup() {
  size(600, 400, P3D);
  background(255);
  noSmooth();
  strokeWeight(1);
  stroke(0);
  line(0, 200, 0, 600, 200, 0);
}

After try with 2 video cards and a lot of experiments I've learned that in Javascript mode it draws the line correctly, but in Java mode not. I'm using Windows 7 (64 bits).
Any idea/advice?
Anyone can draw a black, 1 pixel line in P3D? With wich hardware and software??? I'm going to buy the same...

Thanks!

Hi,

I'm checking the differents rendering modes in 1.5.1 and 2.0 and I am getting many (and surprising) differences.
I'm drawing a simple, black color, line.

stroke(0);
line(0, 100, 600, 100);

and I'm getting all that differents results!

1.5.1 
size(600, 400); -> 1 pixel, black color
size(600, 400, P3D); -> 1 pixel, black color
size(600, 400, OPENGL); -> 2 pixels,  light gray!! (2 pixels? gray?)

2.0
size(600, 400); -> 2 pixel, dark gray!!
etc...

I don't understand anything...Well, sorry if that is well documented. I'm working with Windows 7.
Any idea?

Thanks,
David

Hi there!

I'm trying to make a sketch of a growing rectangle. Yes,yes... that's very easy, I can use scale() or change the rectangle dimensions every frame:

      rectMode(CENTER);
      rect(100, 100, r, r);
      r++;

but I want (I need) to do exactly the same effect using translate() funtion (moving the rectangle towards the z-axis). Something like

      translate(0,0,z);
      rect(100,100,w, h);
      z++;

but that works only is the rectangle center is (widht/2, height/2).
What would be the best way to do that?
Any advice would be appreciated...

Thank you!
David
