Expression to offset animation in time?

[captainblack]

Hi

I would like to set up an expression so that the Transform values of node A are the same as that of node B but a little later. Not sure of the expression syntax for this...can anyone help me out? Thanks!

Pure expressions lingo can only possibly ask current time so youd need mel in your expression (now you must understand this is a VERY bad thing for evaluation of the expression).

$value=getAttr -time (frame-5) nurbsSphere1.translate;
nurbsSphere2.translateX=$value[0];
nurbsSphere2.translateY=$value[1];
nurbsSphere2.translateZ=$value[2];

PS ive lately become aware tough that two maya curve nodes could infact instance eachother atleast the node reference seems to indicate so... Havent got it owrking. If i ever do then that would be the way to go!
