Multiple expressions in one property
Hi there!
I am trying to use 2 expressions in one propertybut I don’t know how to write it correctly.
I have a SampleImage in the Fill effect, but it is in Y position, but I need change the color in X position, and I don’t know how to have the X.How could I use 2 expression in one property?
This is what I have for Y:
Thank you,
Gustarget = thisComp.layer("Color_gradient");
colorpicker = thisComp.layer("BUBBLE MASTER");
target.sampleImage(target.fromWorld(colorpicker.position), [0.2,0.2], true, time) -

What do you mean by that? How are you using x and y?

I have a gradient (blue to red) from the bottom to top that is changing the color when I move in Y position. But I would like to have an Grey area like 20px on the left and when reach some position in X that turns grey.

I’m still a little confused. If there’s an actual grey strip on your gradient, it seems like your expression should work. If you want to force the result to grey when x is less than 20, something like this should work (not tested):
target = thisComp.layer("Color_gradient");
colorpicker = thisComp.layer("BUBBLE MASTER").position;
if (colorpicker[0] < 20){
[.5,.5,5,1]; // grey
}else{
target.sampleImage(target.fromWorld(colorpicker), [0.2,0.2], true, time);
}

Oh, you are right. I just added a grey strip on the left edge and worked perfect.
But I will use your expression in other situation that I have here ????Thank you Dan,
