To joojaa---desperate need for ur help on this!

[glassfairy]

plz joojaa ...help with this!!!

when we instance a obj to the nparticles then all r in one direction is there a way to alter their direction so that they r all aligned or aimed along the curve....

like in

i have tried using rotationpp for per particle with mel script in it but still not working .

i m uploading the file maya file to give a clear view .

http://www.4shared.com/file/DkzEr64E/instrot.html

i put this code into the creation of rotationpp

int $particleCount = particle -q -count nParticleShape1; int $z=0;
for ($n=0; $n<$particleCount; $n++)
{
if ($n<$particleCount/2)
{
$z=($z-10);
}
else {
$z=($z+10);
}
rotate -r -ws 0 0 $z nParticleShape1.pt[$n];
print $z;
}

in the instancer i chose rotation type as rotationpp and rotation as rotationpp

but still the particles are all in same direction of geometry...is something wrong with mel code...i checked the value of $ z and in script editor and it prints it correctly but the particles dont seem to rotate and align themselve along the curvebased on $z.

someone plz guide or better still correct it and then guide so i get fully clear on it.

thnx in advance

Well im not interested in opening your file per see. I just want a good explanation of what you have and why you choose to do it the way you do. Im after correcting your reasoning not doing your work for you.

Anyway your code wont work. Theres nothing to rotate you just need to write the value of rotationPP array attribute directly.

so can shud it be like

int $particleCount = particle -q -count nParticleShape1; int $z=0;
for ($n=0; $n<$particleCount; $n++)
{
if ($n<$particleCount/2)
{
$z=($z-10);
}
else {
$z=($z+10);
}
nParticleShape1.pt[$n]=<>;

}

how to write the value of rotationpp array based on particle count?

i chose to do it this way as nparticle stimulate faster ....i just want u to correct my mistake .not do my work for me.

[joojaa]

The particle expression IS a for loop it should probably look more like:

particleShape1.rotationPP = <>

PLEASE NOTE: Expressions are NOT mel.

just want u to correct my mistake .not do my work for me.

Well where do i start when your not having even the basic assumptions on the right track.
