kill particles on special objects

add attr collisionGeometryIndex to you particle shape and :

int $idx = particleShape2.collisionGeometryIndex;
string $geoC[];
string $shape[];
if( $idx != -1 )
string $geoC[] = `listConnections particleShape2.collisionGeometry[$idx]`;

string $shape[] = `listConnections ( $geoC[0] + ".localGeometry" )`;
print( $shape[0] + "\n");
if ($shape[0] == "killcube") particleShape2.lifespanPP = 0;
