setVlaue() @ rangeController
Sep 30th, 2009, 1:46am  
Hi there,

I'm just using the rangeController from the controlP5 library. I'm trying it this way ight now:
controlP5.controller("rangeController").arrayValue()[1].setValue(.2);

and getting this error:
Cannot invoke setValue(float) on the primitive type float

Doesn't that work at all? Or can I simply use an int instead of an float for an rangeController? It would work with a normal slider, but however doesnt with the rangeController.

cheers

arrayValue() returns an array of floats. float is a primitive type, you cannot invoke methods on them.
It seems that Range has setLowValue(), setHighValue() and setValue() methods. You can invoke them directly on the controller() call result.

i'm sorry, but i don't really get what you mean by this.
i'm getting the same error when trying to change sample rate for an minim audio player object.

Code:
    if (player.isPlaying()) {
	if (player.hasControl(Controller.SAMPLE_RATE)) {
	   float val = map(mouseX, 0, width, 0.0, 44100.0);
	   println(player.sampleRate().setValue(val));
	}
    }


thanks for any help!

I don't know Minim player, but I doubt your question is related to controlP5, is it?
I don't think you quote a relevant part of my message.
sampleRate() probably returns an int or float value. Look at Minim library API to see how to change this sample rate. Might be player.setSampleRate(val) or similar (haven't time to check right now).
