GetAccountNum
From UODemo Wiki
integer getAccountNum(object PlayerObject);
getAccountNum returns the account number of a player object (character). If no valid player object was provided then the function will return 0. Normally, the Avatar character has a fixed account number of 2130706433.
"UoDemo+, Publish 14 and upwards" Server Operators can use the following check to detect themselves (if they didn't override the account number that is):
// Example Code
if( getAccountNum( player_to_check ) == 2130706433 )
{
systemMessage("I am the one running UoDemo+, Publish 14.");
}
