Expression to pull name of group of layers?
Hey guys, so I have a set of layers that moves x amount based on how many layers there are involved.
Is there any way to pull the amount of layers there are in a comp with a name starting with some string? I basically want to be able to add as many layers with some modifier so that the expression works regardless.
For example, all the layers might start with “01_” or something and then any time the expression sees that it could add that to the sum of layers.
Thanks in advance

To retrieve that number, you can use
num = 0;
str = “01_”;N=thisComp.numlayers;
for (n=1; n<=N; n++){if (thisComp.layer(n).name.indexOf(str)===0) ++num;}; // at this stage, num is the number of layers in the comp whose name starts with "01_". // then you use it to calculate your position offset. Xavier
