Color Transition between two Colors by Slider Control

[Sebastian Martinez]

Dear Expression heroes,

my fourth question within a few day – expression rocks:

I want to change the fill of a Shape Layer by a Slider value from 0 to 100.

The Slider Effect is on a Null objekt. But also two Color Control effects, one for the Sliders value at 0, the other for the value at 100.

When animating the Slider between 0 and 100 the color change is supposed to be smooth.

I gave it a try but there was error only:

Col=thisComp.layer("Null 42").effect("Slider Control")("Slider");
color1=[thisComp.layer("Null 42").effect("Color 1")("Color")];
color2=[thisComp.layer("Null 42").effect("Color 2")("Color")];
linear (Col,0,100,color1,color2)

Whats wrong?

Thank you so much in advance,
Sebastian

I guess your only mistakes are the square brackets. You don’t need those, since the link to the color returns an array.

Col=thisComp.layer("Null 42").effect("Slider Control")("Slider");
color1=thisComp.layer("Null 42").effect("Color 1")("Color");
color2=thisComp.layer("Null 42").effect("Color 2")("Color");
linear (Col,0,100,color1,color2)

Stupid me. Too much braketts. This works now:

Col=thisComp.layer("Null 42").effect("Slider Control")("Slider");
color1=thisComp.layer("Null 42").effect("Color Control")("Color");
color2=thisComp.layer("Null 42").effect("Color Control 2")("Color");

linear (Col,0,100,color1,color2)

Anyhow, Thanks to all of you for helping out in this forum, especially Dan!

Take care

Andrei,

yes, the square braketts where too much. I just found it out by myself.

But thank you so much for replying!

Respects
