Help with a script TONIGHT PLEASE

Posted by Adam Forbes on November 12, 2009 at 6:58 am

I need some help fast.

I have multiple projects and thousands of layers so I need a script that will add this expression to every anchor point and every position of a layer:

tempx = value[0];
tempy = value[1];

tempxwhole = Math.round(tempx);
tempywhole = Math.round(tempy);
[tempxwhole, tempywhole]

It’s a simple expression to round the position to the nearest integer which in turn makes the illustrator file appear more clear.

What I need is a script that will apply that expression to all layers selected:

I NEED it ASAP!

Thanks

tempx = value[0]; tempy = value[1];
tempxwhole = Math.round(tempx); tempywhole = Math.round(tempy); [tempxwhole, tempywhole]

Try this:

{
var expr = ‘tempx = value[0];\r’ +
‘tempy = value[1];\r’ +
‘tempxwhole = Math.round(tempx);\r’ +
‘tempywhole = Math.round(tempy);\r’ +
‘[tempxwhole, tempywhole]’;

var myComp = app.project.activeItem;
var myLayer;
for (var i = 1; i <= myComp.numLayers; i++){ myLayer = myComp.layer(i); try{ myLayer.property("anchorPoint").expression = expr; }catch (err){ } myLayer.property("position").expression = expr; } } Dan

Dan,

That’s awesome thanks so much. It doesn’t seem to work for the WHOLE PROJECT. Is there a way to get it to go through every comp in the project instead of just the one I’m in?

Thanks,

Adam

{
var expr = ‘tempx = value[0];\r’ +
‘tempy = value[1];\r’ +

‘tempywhole = Math.round(tempy);\r’ +
‘[tempxwhole, tempywhole]’;

var myComp;
var myLayer;
for (var j = 1; j <= app.project.numItems; j ++){ myComp = app.project.item(j); if (myComp instanceof CompItem){ for (var i = 1; i <= myComp.numLayers; i++){ myLayer = myComp.layer(i); try{ myLayer.property("anchorPoint").expression = expr; }catch (err){ } myLayer.property("position").expression = expr; } } } } Dan

Dan,

That worked great for a while, then it seems to really get tripped up by hidden layers.

It says Unable to execute scrpt at line 19. After Effects error. Can not “set Expression” with this property, because the proptery or a parent property is hidden.

any ideas?

Thanks,
Adam

That’s strange. See if this helps:

{
var expr = ‘tempx = value[0];\r’ +
‘tempy = value[1];\r’ +
‘tempxwhole = Math.round(tempx);\r’ +
‘tempywhole = Math.round(tempy);\r’ +
‘[tempxwhole, tempywhole]’;

var myComp;
var myLayer;
var isHidden;
var isLocked;
for (var j = 1; j <= app.project.numItems; j ++){ myComp = app.project.item(j); if (myComp instanceof CompItem){ for (var i = 1; i <= myComp.numLayers; i++){ myLayer = myComp.layer(i); isLocked = myLayer.locked; myLayer.locked = false; isHidden = myLayer.hidden; myLayer.hidden = false; try{ myLayer.property("anchorPoint").expression = expr; }catch (err){ } myLayer.property("position").expression = expr; myLayer.locked = isLocked; myLayer.hidden = isHidden; } } } } Dan
