Color and Position
Hi everyones
how can i link a color to a position?
What I want is:
if my arrow layer is between for example 100 and 200 on the X axis i would like affect the colors of my red solid who’s having a Fill effect on.
The color between 100 and 200 is blue.
So how should I write my expression to tell to the color fill effect of my red solid to become blue when the arrow is between 100 and 200 on x axis???am i enough clear???
Thank you!!!! -

It will be something like this:
arrow = thisComp.layer("arrow");
p = arrow.transform.position;
if (p[0] > 100 && p[0] < 200)
[0,0,1,1]
else
value
Color values are four-element arrays (RGBA) with values between 0 and 1, so solid blue would be [0,0,1,1].

What happen if i have multiple condition?
the expression was:
arrow = thisComp.layer(“arrow”);
p = arrow.transform.position;
if (p[0] > 100 && p[0] < 200)
[0,0,1,1]
else
valuebut if i have something between another color between 250 and 350 pixel on the x axis? ond still another color between 400 and 500
?
How should write with multiple condition??
Thank you!! -
You could do it like this:
arrow = thisComp.layer("arrow");
p = arrow.transform.position;
if (p[0] > 100 && p[0] < 200)
[0,0,1,1]
else if (p[0] > 250 && p[0] < 350)
[0,1,0,1]
else if (p[0] > 400 && p[0] < 500)
[1,1,0,1]
else
value
