I took a plane with 0-99 points and i want to invert direction of. Velocity randomly by taking point number
For this i used array to store point no.but its only storing one last no.

Float x_array;

{
X_array=rand(@ptnum);
}

in vex wrangels you have two modes:
one runs over every point the other detail will only run once…

You dont need to store the values in an array…

for a great reference to learn vex look here: http://www.tokeru.com/cgwiki/?title=Houdini [www.tokeru.com]

Sometimes you do need to create and store an array; and for that purpose alone you can do the following with the wrangle set to Detail(once only):

float @x_array[];
float Randomized;

for( int c = 0; c < npoints(geoself()); c++)
{
Randomized = rand(c);
push(@x_array, Randomized);
setpointattrib(geoself(), "point", c, Randomized , "set");
}

However, if just want to assign those values to each point just have your wrangle set to run over points with:

f@Random_V = rand(@ptnum);
