Randomizer on 3 Grouped buttons, How?

[d.healey]

@DanH Why not put the randomizing code you have in your button callbacks inside the sliderpack callback? And then all the buttons need to do is change the sliderpack value and trigger its callback.

[DanH]

@d-healey argh making a mess of this lol! I think I've misunderstood your suggestion... (or which bit of the code to switch out into the sliderpack callabck)

[d.healey]

@DanH The button callback contains some code that randomizes the filter. Take that code and put it in the sliderpack callback.

[DanH]

@d-healey do you mean this code?

inline function onRandITControl(component, value)
{

    local randomValue = Math.randInt(0, 5);
    Console.print(randomValue);   
    
    btnRandom[randomValue].setValue(1);
    btnRandom[randomValue].changed();

};

Content.getComponent("RandIT").setControlCallback(onRandITControl);

[d.healey]

@DanH No, I'm talking about the code that randomizes the filter. The part that sets the attributes.

[DanH]

@d-healey so this?

Filter1.setAttribute(3, FilterModes[idx]);
Label1.set("text", FilterNames[idx]);

If so I've been trying to figure out how to get the idx value (from the button callback) into the sliderpack callback

[d.healey]

@DanH Think of it this way: the buttons are only there to provide an interface for the user, you don't need them (except for the randIT button). So write your code so that is uses the sliderpack instead of the buttons, once you have that working you can add the buttons back into the mix.

[DanH]

@d-healey I still need the 'Tabbed Interface' script though don't I?

[d.healey]

@DanH I'm not seeing a tabbed interface in your snippet

[DanH]

@d-healey So the buttons are the 'tabs' if you like. In order that they behave like a radio group.

//// TABBED INTERFACE SCRIPT

const var NUM_TABS = 5;

for (i = 0; i < NUM_TABS; i++)
{
    btnRandom[i].setControlCallback(changeTab);
}

//Tab button callback function
inline function changeTab(component, value)
{
    //Get index of clicked button
    local idx = btnRandom.indexOf(component);
    //Toggle buttons
    for (i = 0; i < btnRandom.length; i++)
    {
        
        if (i == idx)
        {
            btnRandom[i].setValue(btnRandom[i] == component);
            SliderPack1.setSliderAtIndex(idx, btnRandom[idx] == component);
            Filter1.setAttribute(3, FilterModes[idx]);
            Label1.set("text", FilterNames[idx]);
        }
        
        else
        
        {
            btnRandom[i].setValue(0);
            SliderPack1.setSliderAtIndex(i, btnRandom[i] == component);
        }
    }

}

[d.healey]

Rewrite it without the buttons at all. They are only there to provide an interface for the user, they are not important for the functionality. Once you have it working without the buttons you can re-add them (with the radio behaviour too).

[DanH]

@d-healey Thanks for all this David - ok I'm trying this but am unclear on a few things. Trying to store the random number inside the 'btnRandom' array and use that to call the right filter mode in the Sliderpack callback. Not sure why I'm getting this error though:

Line 42, column 25: API call with undefined parameter 1

[d.healey]

@DanH What do you expect this to give you (keep in mind that this is in the sliderpack callback)?

local idx = btnRandom.indexOf(component);

[DanH]

@d-healey Well, one of the things I'm unclear on sliderpack callabacks

I have no idea how they are supposed to look!

[d.healey]

@DanH Same as any other control. But your slider pack isn't in the buttons array so looking for it in there will return -1.

The value parameter of the callback will give you the number of the slider that was moved.

[DanH]

@d-healey Oh right, so then I don't even need to get the value of the 'btnRandom' array then I guess, will give a go tonight

[d.healey]

@DanH Yeah, like I said, you can do the whole thing without the buttons. The buttons are only needed to provide a nice interface for the user.

[DanH]

@d-healey So two issues now, firstly the random button doesn't trigger the SliderPack callback. Should

SliderPack.changed();

work? Doesn't seem to be.

Secondly using the value parameter inside the SliderPack callback sets the filters every time a slider is engaged - probably better to have it only when it's value is 1.

@DanH said in Randomizer on 3 Grouped buttons, How?:

the random button doesn't trigger the SliderPack callback

Sure it does. Put a Console.print in your sliderpack callback and then click the button.

probably better to have it only when it's value is 1.

I agree.

[DanH]

@d-healey

Sure it does. Put a Console.print in your sliderpack callback and then click the button.

I just get 'Interface: [Array]'

The sliders move when clicking the random button but the filter and label don't.
