Change color based on time
I have a little question here: I need to make a bunch of buttons cycle through a number of colors over time.
I have some foggy notion about setting up a ramp containing the needed colors, but I don't have even the foggiest notion about how to get any information about the current frame number.
And even if I get this time information: how do I normalize it to propperly access the ramp?
How do I achieve this?
Seems that the question is not that little, eh?
Thanks anyway,
Mario

The easiest way, probably, would be to simply keyframe the color information and then cycle the animation in the Graph Editor. This method doesn't use a ramp.

I Just added a 'time' attribute (ranging from 0-1) and used this to access the ramp.
I needed to do a number of different flashy buttons with different colors and a different cycle timing, that's why I put all the color information in a ramp. That way, I could change colors and timing just by pushing the ramp's colors around a bit.
Thanks for the tip anyway.
