Printing particle position

[patrick-geoffroy]

Hi, 

I'm trying to create a file with 3 columns being the position of the particles.

So far if I do this for particle ID "1" it works:

float $speck[] = getParticleAttr -at position -array true particleShape1.pt[1];

// Result: -1.297178 0.190271 0.777298 //  

So to get this for every particle, so each line is the X Y Z position, I'm trying this but with no success:

for  ($i =0; $i < 5; $i++)
{
float $speck[3] = `getParticleAttr -at position -array true particleShape1.pt[$i]`;
print $speck;
} 

-0.1848040.153196-0.178653-0.2324440.0340950.139286-0.155550.0182010.189369

How can I obtain something like this:

X Y Z
X Y Z
X Y Z
and so on

because 

{float $speck[3] = getParticleAttr -at position -array true particleShape1.pt[$i];
print ($speck + "/n");};

// Error: print ($speck + "/n");
// // Error: Illegal operation "+" on data of type float[]. // 

Any idea?

Thanks

I figured out a way, it might not be the best one but it works.

int $NombreDeParticules = particle -ct -q;
for ($i=0;$i<$NombreDeParticules;$i++)
{
float $speck[] = getParticleAttr -at position -array true particleShape1.pt[$i];
string $speckX = ( string ) $speck[0];
string $speckY = ( string ) $speck[1];
string $speckZ = ( string ) $speck[2];
print ($speckX + " " + $speckY + " "+ $speckZ + "\n");
};
