existence ?
I’m using such expression to read some value:
target=comp(thisComp.layer(1).name).layer(thisComp.name);I need to automatically target nothing or something else when the target is not available for a moment (no existence)
(in order not to have an error like this: “impossible to find…”)I don’t want to switch on/off each time all this expression.
it may be something with if(…) has…
Help please !

You can use JavaScript’s try/catch construct for this, like this:
try{
target=comp(thisComp.layer(1).name).layer(thisComp.name);
}catch(err){
target = // something else
}In the catch section you have to define what value to use for target if the try section fails.

Now i need to read the reel scale of a parented layer.
I don’t understand yet the difference between World and Comp but i remember Dan your expression:L = comp(“target”).layer(“target”);
P = L.toComp(L.L.anchorPoint);so i’ve tried with no luck
L = comp(“3×1”).layer(“LIGNES”);
P = L.toComp(L.transform.scale);Can ask you one more time ?

Try this:
L = comp(“3×1”).layer(“LIGNES”);
if (L.hasParent){
s1 = L.parent.transform.scale;
s2 = L.transform.scale;
[s1[0]*s2[0]/100, s1[1]*s2[1]/100]
}else{
L.transform.scale
}Dan
