  Add expression to selection of properties

  Posted by Pascal Miller on January 23, 2018 at 10:16 pm

  Hello,
  I’m trying to write a script that will add the posterizeTime(); effect and add it to all selected properties. If a given property does not have an expression (say it only has keys), it will create the expression, and if there is an existing expression already there, it will add the posterizetime at the top of the expression (to preserve the existing expression)

  Is this hard?

  Thanks in advance!

  This should not be so hard. Should look like thisif (layerProperty.expression == ''){ //the layer does not have an expression
layerProperty.expression = yourExpression;
}else{ //the layer already has an expression
expr = layerProperty.expression;
layerProperty.expression = yourExpression +'\n'+expr;
}

  layerProperty should be the property you choose and yourExpression should be the expression you use. The ‘\n’ is used there as an empty line.
