Like this:
for (int i=0; i<4; i++)
{
    i@P`i` = i;
}

Im trying to create multiple detail attributes like @P0/@P1/@P2/... Tried multiple expressions but all only output a single @Pi..

Any way to achieve that? Thanks!

for (int i=0; i<4; i++)
{
    string name = "P" + itoa(i);
    setdetailattrib(0, name, i, "set");
    //setdetailattrib(0, name, i);
}

Hello, check the attached example file and see if it works for you.

As far as I know the most performant way to dynamically create attributes is to use an Attribute Create inside a feedback loop block.
I never checked python based solution, however.
