Is there a way to trigger the color of the background

EYESY
1

Would anyone know the way to have the background color (knob 5), change when an input trigger is received? thank you in advance.

background colour is changed with etc.color_picker_bg(val)
you can instead use etc.bg_color= color(r,g,b), if you don’t want to use the ‘normal’ colours select by knob5.

btw: handy tip, colour_picker_bg() returns the colour selected… useful for storing…

a trig is detected, by looking for etc.audio_trig=True

so using these, you could do something like use a different colour when the trig is received.

iirc, (i.e. need to go boot my eyesy :wink: ) the knob5 to bg colour selection is done in each individual mode… so you have to change in each mode you want to have this happen.

@oweno have you got a repo for the eyesy modes?
there are some differences from the ETC_Modes repo e.g. for knob5.
(i sometimes use the repos, when I just want to check a patch without booting up a machine :slight_smile: )

Yes, the modes are now organized in their on repository:

I am new at this, I know some code, still becoming familiar with python, so I am editing the slideshow mode and I put the trigger into the source of where the (knob5) was and i can get the colors to trigger, But only black and white. can I get it to filter though the colors available?

def draw(screen, etc) :
global images, image_index, last_screen, nest, bgi, bgi2, trigger, xr, yr
etc.color_picker_bg(etc.audio_trig)
trigger = False

if you look at the modes code, you will find the ‘normal’ implementation is etc.color_picker_bg(etc.knob5)
etc.knob5 returns 0 to 1.0

this is a actually a continuous set of colours, moving thru an RGB palette, rather than a sequence you could ‘step thru’…

but as an example you could do something like (pseudo code, only!)

if etc.audio_trig > 0  :
    bg_colour = bg_colour + 0.1
    if bg_colour > 1.0 : 
      bg_colour = 0.0
    etc.color_picker_bg(bg_colour)

this would then cycle thru 10 colours ( 1.0/0.1 = 10 )

if you wanted to cycle thru a known set of colours (e.g. specified by rgb values) , you could store these in an array, and then cycle thru that array each time audio trig was received.

note: you also might want to do a more ‘elaborate’ code , such the colour only switch when a trig is received, and then waits for audio to drop below a threshold before it re-trigs. but I’ll leave that as an exercise for the reader :wink:
