Hi ,

I m not a mel expert , but with "for" you need to have the {} ...


for($i = 0; $i < $35; $i++)
{
$champagne = rand(2, 5);
$bubbles = rand(10, 20);
}

Here my 2 cents....

hope it helps...

You may check Maya help, look under:
> "MEL and expressions" > "Controlling the flow of a script" > "for"
> "MEL and expressions" > "Values and Variables"

They have some good tutorials to follow too.

Best,

Hi,


there shouldn't be anything wrong with that code... did you have the snapshot1Group selected when you executed the script?

the $tname is used for creating a variable... e.g. if you look into your snapshot1Group after creating the Animated Sweep...
that they e.g. are named transform1_1 upto transform1_35
(or whatever snapshot group you might have it in)

what does the code more do...
the "setKeyframe -at "nodeState" -v 2 -t 0 $tname;"
makes the curve which have the $tname based on the $i value "inactive" from frame 0...
until the "setKeyframe -at "nodeState" -v 0 -t $i $tname;"
makes the curve which have the $tname based on the $i value "active" at the frame value of $i...

e.g. let's take the curve named transform1_14...
"setKeyframe -at "nodeState" -v 2 -t 0 transform1_14;"
will make transform1_14 "inactive" from frame 0 until we get to frame 14... where...
"setKeyframe -at "nodeState" -v 0 -t 14 transform1_14;"
will make transform1_14 "active" again at frame 14...

when you run the code you should just select your snapshot group in which you have the curves...

I have made a little change to the script... just change the snapshotgrp name "select -r snapshot1Group;"
if you have the curves in another snapshotgrp... :)

hope that helps a bit... :)

kind regards

Strarup



proc makeDaSweepGrow()
{
select -cl;
select -r snapshot1Group;
for($i=1;$i<35;$i++)
{
$tname = "transform1_"+$i;
print($tname + "\n");
setKeyframe -at "nodeState" -v 2 -t 0 $tname;
setKeyframe -at "nodeState" -v 0 -t $i $tname;
}
}
makeDaSweepGrow;

be carrefull $tname is not declared, you need to declare this variable (if you don't do that it will not work) :

string $tname = "transform1_" + $i ;
