change color according to value

[Ido Shor]

Ok…. I am probably way off here, because my knowledge in expression is almost limited to a Wiggle… 🙂

but just to show you I am making an effort, and maybe sparkles an idea in one of your brilliant minds.. here goes a test I did:

————————————————————————————————————————————–

upColor = thisComp.layer(“Ctrl”).effect(“Up Color”)(“Color”);
downColor = thisComp.layer(“Ctrl”).effect(“Down Color”)(“Color”);
value = thisComp.layer(“Ctrl”).effect(“Slider Control”)(“Slider”);
prevframe = thisComp.layer(“Ctrl”).effect(“Slider Control”)(“Slider”).valueAtTime(time – thisComp.frameDuration);

if(prevframe.valueAtTime < ((time * 25) % 2 == 0).valueAtTime))downColor else upColor;

value;

————————————————————————————————————————————–

And a screen capture of my comp attached.

so… basically I am trying to get a value from a place that doesn’t has one… (linking the source of the text to a slider)

any ideas how to solve this nut?

Not sure if I understood what you wanted to achieve, but let’s say try to put this line in the Fill’s Color attribute

UC = thisComp.layer("Ctrl").effect("Up Color")("Color");
DC = thisComp.layer("Ctrl").effect("Down Color")("Color");
S = thisComp.layer("Ctrl").effect("Slider Control")("Slider"); //determines how many times per-second the color will change
if (1-Math.round(time*S)%2) UC else DC;

Hey Hammer, tnx, but it seems ur code is making the letters flash back and forth from one colour to the next.

in the meantime, with the help of Xavier from Adobe forums we managed to achieve this code:

——————————————————————————————

upColor = thisComp.layer(“Ctrl”).effect(“Up Color”)(“Color”);
downColor = thisComp.layer(“Ctrl”).effect(“Down Color”)(“Color”);
X = thisComp.layer(“Ctrl”).effect(“Slider Control”)(“Slider”);
ta = time – thisComp.frameDuration;
a = X.valueAtTime(ta);
b = X.value;
while (a===b && ta>=inPoint){
b=a;
ta -= thisComp.frameDuration;
a = X.valueAtTime(ta);
};
if (b
