Reply To: Looking to change button image on value change

[goodweather]

Well, even if the code above is working, the simplest is just to have 2 uiImageSliders modulators:
– one to select the waveform: use an image of a 4 position button, values 0-3
– one to display the wave: use an image with your 4 waveforms, values 0-3

When changing the waveform button, change the value of the wave modulator to the same value with a small Lua code (uncomplete code below but to give you the idea)

--
-- Called when a modulator value changes
-- @mod   http://ctrlr.org/api/class_ctrlr_modulator.html
-- @value    new numeric value of the modulator
--
Wave_OnChange = function(--[[ CtrlrModulator --]] mod, --[[ number --]] value, --[[ number --]] source)
modWaveform:setValue(value, true)
end

Look at my OscShape_OnChange method in my Pro2 panel. Button OSC 1 Shape/noise for example.
It is more complex than what I describe above because I’m also adapting the LCD screen, enabling/disabling other pulldowns based on the wave selection…

But the way I propose is easier than using custom components.
Anyway, in programming, there are always many different ways to achieve the same objective 😉
