expression to trail????

[Mike Clasby]

This is a modification (scale for position) of the first expression on Dan’s page on Trails:

delay = 10; //number of frames to delay

d = delay*thisComp.frameDuration*(index – 1);
thisComp.layer(1).position.valueAtTime(time – d)

To make this work the first layer to scale is the top layer (layer 1) and the expression goes on the layer you want to follow in its scaling. There can be other layers in the comp, the lead scaling layer just needs to be the top layer.

Here’s the page:

Opps. It was later when I wrote that so I grabbed the unmodified expression, here’s the right one (“scale” subbed in for “position”):

delay = 10; //number of frames to delay

d = delay*thisComp.frameDuration*(index – 1);
thisComp.layer(1).scale.valueAtTime(time – d)

It’s the “scale” in the bottom line that’s now right, last night’s had “position” there as in Dan’s original expression, sorry ’bout that.
