dynamic motion using expressions
Is there a way to create a “string” of objects that can move through 3D space which can seem to move relatively to the velocity to object 1 in the string? Meaning the space between the objects would be dictated by how fast Object 1 was moved, creating a sort of flexible buffer between the rest of the objects. Secondly is ther a way to then change how many objects are in that same string with out making the string any longer? I know that there is probably a lengthy explanation to this and any help would be much appreciated.
Thanks for your help.

I think an expression like this would work for layers 2 thru n:
totalDelay = .5; // delay of last object (seconds)
myDelay = totalDelay/(thisComp.numLayers – 1)*(index – 1);
thisComp.layer(1).position.valueAtTime(time – myDelay)As layer 1 speeds up the string will spread out. As you add more layers, the others will squeeze together to make room. The expression assumes there aren’t any layers in the comp except the leader and the followers. Adjust “totalDelay” to get the spacing you want.

This is my favorite of your Follow the Leader Expressions, it’s so organic and loose.
