1 Knob for several value

d.healey

I see what you were thinking, but I see why it's not working. Can you tell me why this won't work?

	if(0)
        { 
	EQ.setAttribute(EQ.Freq, 20);
	}
	
	if(1)
        { 
	EQ.setAttribute(EQ.Freq, 40);
	}
	
	if(2)
        { 
	EQ.setAttribute(EQ.Freq, 60);
	}
	
        if(3)
        { 
	EQ.setAttribute(EQ.Freq, 80);
	}

mais je vois pourquoi cela ne fonctionne pas. Pouvez-vous me

if(Knob1 == 0)
if(Knob1 == 1)
.....
.... ?
I'm going to get carried away again ^^

@yall

I'm going to get carried away again ^^

Hopefully :)

if(Knob1 == 0)
if(Knob1 == 1)

This would (almost) work, but this isn't what you wrote.

An if statement is always performing a comparison and checking if the value is true (true in this case means not 0).

So what you wrote

if (0) will be false
if (1) will be true
if (2) will be true
etc.

You need to write a comparison instead of just writing a value.

For example you can take the knob's value which is passed into the callback as the value argument.

if (value == 0) {}
if (value == 1) {}
if (value == 2) {}

Another way you could do this is with a switch statement, and another way is to store the values you want to set in an array and use the knob's value as the array index.

yall

ah yes I understood, however how now to control the combo box from the knob?
the values of the combo box are 0 1 2 and 3? for the different lines?

Did you try setting the combobox's value from the knob's callback?

yall

I tried CB.setValue (1);
CB.changed ();
but I am sure it is a beautiful mistake.

d.healey

@yall

tried CB.setValue (1);

Do you want the combobox's value to always be 1?

yall

what did you have against the number 1? ^^
no it obviously has to change but I admit that I don't know

d.healey

@yall Do you want it to change to the knob's value?

yall

inline function onKnob1Control(component, value)
{
if(value == 0)
{
CB.setValue(1);
}

 if(value == 1)
    { 
CB.setValue(2);
}

};

Content.getComponent("Knob1").setControlCallback(onKnob1Control);

i understand i know

yall

@d-healey
I just got there, I didn't put the .changed
thank you .
you won 1 week of vacation with me in the south of France (facing the sea;))

d.healey

Well done!

I'll show you a slightly more efficient way that will only use one line in the callback

CB.setValue(value + 1);

yall

@d-healey said in 1 Knob for several value:

CB.setValue(value + 1);

i will try now

yall

even simpler. yet these are things that I see often, I understand them but I don't have the reflex to apply them correctly.

thanks a lot

It just takes practice. Read lots of code and write lots of code and you'll pick these things up.

One tip, if you find you are writing the same thing multiple times then there is probably a more efficient solution.

yall

@d-healey yes I try more and more to write the codes with what I learn rather than doing stupid copy paste. I am creating a github to host my projects in order to sell them with the open license and I will send you all of this. you will surely be surprised for a little beginner Like me ^^
