Is it possible to check if layer has an effect applied to it
I need to check if a layer below a layer has an effect applied to it.
The problem I’m running into is if the effect doesn’t exist AE throws an error and disables the expression. Is there a way around this? I’ve tried other variations with little luck.My goal is to check if the layer below has a checkbox effect applied to it, then to check the value of the checkbox.
if(checkbox exists && checkbox == true){
50;
}else{
0;
}if(thisComp.layer(index+1).effect("My Checkbox")("Checkbox")!= undefined && thisComp.layer(index+1).effect("My Checkbox")("Checkbox")==true){
50;
}else{
0;

I think I’d do it this way:
try{
if (thisComp.layer(index+1).effect("My Checkbox")("Checkbox").value == 1) 50 else 0;
}catch (err){
0;
}
