Compare two values
Hi,
Is there an expression that can operate like a comparison node, as in compare 2 values and pick one.
For example – compare 2 layers’ x-position values, pick the larger one and set that layer’s opacity to 0%.
Or something to that effect?
Cheers

Both layers would need an expression applied to opacity:
1st layer:
l1=thisLayer;
l2=thisComp.layer("second layer");if (l1.position[0]>l2.position[0]) {
100;
} else {
0;
}
The 2nd layer could just have an expression for opacity like:
l2=thisComp.layer("first layer");
100 - l2.opacity;
or you can re-use the first expression and change the first two lines to:
l1=thisComp.layer("first layer");
l2=thisLayer;if (l1.position[0]>l2.position[0]) {
100;
} else {
0;
}

Obviously, in that last expression 100 and 0 need to be reversed
l1=thisComp.layer("first layer");
l2=thisLayer;if (l1.position[0]>l2.position[0]) {
0;
} else {
100;
}

Works like a charm.
Nice work Filip, thanks for helping out.
