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());
     }
   }
