Laying out layers with set gaps and random scale
Hi all,
I’ve got this to work fine; sits on the position of each layer.
total = 0;
for (i = 1; i<=(index); i++) { total += thisComp.layer(i).width * (thisComp.layer(i).scale[0]/100) } total += 20; //gap in pixels [total, 300] The problem is it only works when the anchor point is 0 on the x axis. I want the objects to scale from the centre of the object - not the edge. I've figured that the maths is something like this: total += ((thisComp.layer(i).width * (thisComp.layer(i).scale[0]/100))/2) + ((thisComp.layer(i-1).width * (thisComp.layer(i-1).scale[0]/100))/2) But it doesn't seem to work... :o( Any help?

It always happens – I post and then get it to work 2 minutes later… :o)
total = 0;
for (i = 1; i<=(index); i++) { if (i==1) { total = (thisComp.layer(i).width * (thisComp.layer(i).scale[0]/100))/2; } if (i > 1) {
total += ((thisComp.layer(i).width * (thisComp.layer(i).scale[0]/100))/2) + ((thisComp.layer(i-1).width * (thisComp.layer(i-1).scale[0]/100))/2);
total += 20;
}
}
[total, 350] -
Go faster stripes version;
total = 0;
for (i = thisComp.layer(“iconstart”).index+1; i<=(index); i++) { if (i >thisComp.layer(“iconstart”).index+1) {
total += ((thisComp.layer(i).width * (thisComp.layer(i).scale[0]/100))/2) + ((thisComp.layer(i-1).width * (thisComp.layer(i-1).scale[0]/100))/2);
total += 10;
}
}
[thisComp.layer(“iconstart”).transform.position[0]+total, thisComp.layer(“iconstart”).transform.position[1]]Requires a null object named “iconstart” and then all your layers underneath it.
