Expressions through MEL .. need help

[Anonymous]

Im working on simple script in which I want to connect some attributes with sine of Time through MEL

there are 20-40 grass planes. each has "RandValue" attributes in them. There is Main control where I want to Control all plane's speed by its speed attributes.

...here is the script

     
string $sel []=`ls -sl`;

for ($eachObj in $sel)
{

expression -o $eachObj -s  "rx =  sin (frame)  * $eachObj.RandValue * ctrl.Speed;";

//--- Here the ctrl is control for speed.

but something is wrong and getting errors.

There were a couple of problems with your string and the expression.
this seems to work.

string $sel []=`ls -sl`;
for($eachObj in $sel)
     expression -s ($eachObj+".rx=sin(time*"+$eachObj+".RandValue)*ctrl.speed;") ;
