Let’s say you want to control the size of a rectangle that you defined somewhere (ofRectangle rect). Register a lambda function with the patchbay, giving it a human-readable name. The closure should accept a parameter value, which will be a float in the range [0,1]
patchbay.registerControllable1f("rect-size", [&] (float value) {
rect.setHeight(100 * value);
rect.setWidth(100 * value);
});
Now you can connect the x-position of the mouse to the registered parameter:
patchbay.connect1f("mouse-x", "rect-size");
You can disconnect them like this:
patchbay.disconnect1f("mouse-x", "rect-size");
And hook it up to a MIDI controller:
patchbay.connect1f("midi-cc-10", "rect-size");
Or even audio:
patchbay.connect1f("audio-rms", "rect-size");
Installation
Define these objects in ofApp.h
ofxPatchbay patchbay;
ofxPatchbayInput input;
And add this line to ofApp::setup()
input.registerInputs(patchbay);
And call update() on ofApp::update()
patchbay.update();
