You need first to format it and then use the name of it.

pawn Код:

// opening file for playerid
new tmp[32];
for(new v = 0; v < MAX_PLAYERTOYS; v++)
{
    format(tmp, sizeof (tmp), "pt%dModelID", v);
    INI_WriteInt(File, tmp, PlayerToyInfo[playerid][v][ptModelID]);
    format(tmp, sizeof (tmp), "pt%dBone", v);
    INI_WriteInt(File, tmp, PlayerToyInfo[playerid][v][ptBone]);
    // continue the rest like that
}
// closing file for playerid

By the way, modelid and bone are integers not floats. Be careful on those!
