Maya for 3D Printing - Rapid Prototyping
In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

expression via mel
I have a question concerning expressions via mel script. for some reason it seems to work - no errors... but no expression is being written into the locators. (i have particle called pLetter_Zero. then want to figure out the particle-count, create as many locators and place them to each particle via expression)
any input is much appreciated!
int $partCount = `getAttr ("pLetter_Zero" + ".count") `;
for( $i=0; $i<$partCount; $i++ ) {
spaceLocator -n ("pLocator" + $i);
string $particleLocator[] = `ls -sl`;
string $exprX = ($particleLocator[0] + ".tx");
string $exprY = ($particleLocator[0] + ".ty");
string $exprZ = ($particleLocator[0] + ".tz");
string $cmd = " \
float $particlePos[] = `particle -id $i -at worldPosition -q pLetter_Zero`; \n\
$exprX = $particlePos[0]; \n\
$exprY = $particlePos[1]; \n\
$exprZ = $particlePos[2]; \n\
";
expression -s $cmd;
}
everything starts and ends in the right place at the right time.
