Linking a text parameter to a slider
Hi,
A have a precomp within a master comp. I have a number of layer in a precomp whose position are all linked to another layer (NULL 2) in the master comp which looks like this:
comp.(“MasterComp”).layer(“NULL 2”).transform.position
The project will have to go through multiple revisions so I’ll be making multiple versions of the master comp. I’ll also have to duplicate the precomp and then replace every time I make a new version to insure that each new version is self contained and I’m not messing up any previous comps. Since this means that I’ll have to edit the expression in each layer of the new precomp is there a way of linking the name of the master comp to a slider? So basically instead of having to write MasterCompV2, MasterCompV3, etc. over and over again in each of the layers of the precomp, if I could do something like MasterCompV(Slidercontrol) I would just have to type in one number and that would save me a ton of work/time.
Any thoughts?
Thanks in advance for all your help,
-Josh

Javascript supports implicit conversion from number to string, so
"foo" + (Math.floor(thisComp.layer("control").effect("Version Slider")(1)))
gives you “foo1” if your slider’s value is >= 1 but < 2, etc. Xinlai Ni Software Engineer, Google Inc. -
THanks for the quick response!
So here’s the expression I made based on yours:comp(“TestV” + (Math.floor(thisComp.layer(“VersionControl”)(“Slider”)(1)))).layer(“MOVER”).transform.position
But I’m getting this error:
Expected:;
Error ocurred at line 1.
Comp:’PrecompTestV1′
Layer: 2 (‘Null137’)
Property: ‘Position’
