View Full Version : angleBetween problem

Howdy. Here's the code snippet:


for ($inc=0; $selectCount-1; $inc++)
{
$rval1 = $jointRotVal[$inc] ;
$rval2 = $jointRotVal[$inc+1];
$getAngle = `angleBetween -euler -v1 $rval1 -v2 $rval2 -ch on`;
}

Here's the problem:

angleBetween -euler -v1 0 -6.362 -1.264 -v2 0 -2.162 -3.444
// Error line 118: Invalid linear unit: 0 -6.362 -1.264 //

Basically, I'm just iterating through a series of joint location coordinates to figure out the angle between them so I can accomplish some other things.

$jointRotVal is a VECTOR
$rVal1 and $rVal2 are both strings, but I've tried making them vectors as well to different but equally frustrating results.

Am I just building my statement incorrectly? It looks OK to me, but maybe I'm missing something a fresh set of eyes will spot.

Thanks in advance.

Heya,

I've found that maya has probs with vectors in mel scripts.. try putting them explicitly with the .x, .y, and .z..


for ($inc=0; $selectCount-1; $inc++)
{
$rval1 = $jointRotVal[$inc] ;
$rval2 = $jointRotVal[$inc+1];
$getAngle = `angleBetween -euler -v1 ($rval1.x) ($rval1.y) ($rval1.z) -v2 ($rval2.x) ($rval2.y) ($rval2.z) -ch on`;

}

for ($inc=0; $selectCount-1; $inc++)
{
$rval1 = $jointRotVal[$inc] ;
$rval2 = $jointRotVal[$inc+1];
$getAngle = `angleBetween -euler -v1 $rval1 -v2 $rval2 -ch on`;
}

Damn, I thought I'd tried calling them explicitly. That did it.

Thanks Jason.
