MAYA: Linking parameters over time

If i want to script pSphere1 so it at frame 21 has the translation values of pCube1 at frame 2... how could that look?
i want to automate the animation of several objects and all should be timeshifted from the first one
and with the offset as a variable
so i have to point at translation values at a certain frame

pseudocode: pSphere1.translation = pCube1.starttranslation*(thisframe-2)/19 + pSphere1.starttranslation*(21-thisframe)/19
just a basic tweening equation between two values, shifting the weighting factor over tie
time*

oh
so "thisframe" is acctually a "variable" that wrks?
hmm
must test

of course not, its pseudocode

pseudocode =)
heheh
didn't read it all

I suppose you could use a dummy object with a custom attribute to store an animation curve go get better control over how it moves between them over time aswell
go=to*

there is acctually a timeFunction node in maya that trax uses
maybe something that one can use

Im sure there has to be a global variable like "frame" or something
but the code wont work if you plan to animate the objects manually as well. Then you'd have to query the position of the objects at every frame or make some other expression that will update the variables automatically when the position change
there's TONS of cool stuff you could do with this, hehe
procedural animation is awsome
