coloring text based on numbers from an array (list)
So I have the following expression that takes a number from a list and puts it up on the screen every six frames (30 fps). Works great. Now i need compare each number from the list to the following and change the color of the test accordingly:
0-100 – Green
101-140 – Yellow
141 – 160 – Orange
161 – Up – RedI’ve tried to use different animator descriptions and changing the hue/saturation, but to no avail.
Any ideas would be greatly appreciated.
Thanks.
// expression to take input of series of numerical values and display them five per second or every six frames
// get our source list
listText = thisComp.layer("heart").text.sourceText;// now make an array, assuming a comma delimiter
list = listText.split(",");// what's the biggest value? we'll use this as our denominator
maximum = Math.max.apply(Math, list);// which number should we look at? one per six frames
wholeSeconds = Math.floor(time-inPoint);
milliSeconds = Math.floor(((time-inPoint) - wholeSeconds) * 1000);
indexModifier = Math.floor(milliSeconds/200);
target = (wholeSeconds*5) + indexModifier;// make sure we don't try to find the value-as-a-percentage for an out-of-bounds array number, or try to divide by zero
if ((target >= 0) && (target < list.length) && (maximum != 0)) {// this will print to screen the array number or zero
speed = list[target];
} else speed= 0; -

Assuming that you’re using an RGB fill animator and “n” represents your number, something like this for fill color should work:
if (n <= 100)
[0,1,0,1]
else if (n <= 140)
[1,1,0,1]
else if (n <= 160)
[1,.5,0,1]
else
[1,0,0,1];

that works good, but returns whatever’s between the square brackets… How do I get that number to return and change in the text’s color?
Thanks again.

I’m lost. I would only work as part of an expression for Fill Color.

This was great! thanks…. It took me a bit to think to put the code in under “color” lol.
