I think you might want to check out the [pack] object. Feed the three numbers into [pack 0 0 0] and the output of that into a 'color $1 $2 $3' message and it will change the color of the background whenever the left inlet of the [pack] gets a bang. I use a [t b] and attach the rest of them numbers to that and feed it into the [pack], that way each number will trigger the [pack] to spit out the list. I really should write an [autopack] object that updates whenever any inlet receives a message.

hello list,

I am trying to animate the color of GemWin. But I have a problem: I tried the color and colorRGB objects and GemWin doesn't accept them; it is possible to use "color R G B" messages only. So, my problem is in composing the message using variable values for R, G and B (it would be easy if I could use some color object). It is a very basic question, I know, but I haven't found very much documentation about the logic of Pure Data (I work well with programming languages like C, but I still don't know how to make a lot of things in patches...).

I am sending the patch. If somebody could take a look at it, i would thank you a lot.

bye, andrei
