Layer Control to drive opacity of a single layer

[Craig Kristensen]

I have been trying to get something like this to work.
I have a text layer that reads the value of the Layer Control using:
thisComp.layer(“— SELECT”).effect(“Selector”)(“Layer”).name

And then using this on the opacity for each layer to check if the “FRANCHISE NAME” equals the name of the layer. If so, “then opacity = 100”
ifi(thisComp.layer(“FRANCHISE NAME”).text.sourceText = (“thisLayer.name”)) 100 else 0;

But I’m having some syntax troubles.

[Craig Kristensen] “I have a text layer that reads the value of the Layer Control using:”

Layer Controls cannot be keyframed, so this value will be constant throughout the comp. It doesn’t sound like that’s what you want.

[Craig Kristensen] “ifi(thisComp.layer(“FRANCHISE NAME”).text.sourceText = (“thisLayer.name”)) 100 else 0;
“

Here’s the correct syntax:
if (thisComp.layer("FRANCHISE NAME").text.sourceText == thisLayer.name) 100 else 0;

1) It’s “if” not “ifi”.

2) Equality comparison uses “==” not “=”.

3) There is no reason to enclose thisLayer.name in quotes and parentheses. “name” is an attribute of the object called “thisLayer”.

Works perfectly!

Is it possible to use a Layer Control to select layers in a different comp?

[Craig Kristensen] “Is it possible to use a Layer Control to select layers in a different comp?”

No, but you could refer from your main comp to a layer control effect on a layer in a different composition:

comp("OTHER COMP").layer("— SELECT").effect("Selector")("Layer").name

You can precomp . Then drag out timelines for the precomp and the comp and then pick whip across.

I have done it.
