Emblem-important-red.png Usage Warning!

There is no way to determine the success of a llGiveMoney transaction. If you need to know if a transaction was successful, use llTransferLindenDollars instead of llGiveMoney.

Summary

Function: integer llGiveMoney( key destination, integer amount );

Transfer amount of L$ money from script owner to destination avatar.
Returns an integer that is always zero. In contrast llTransferLindenDollars returns a key that can be used to match the function call to the resulting transaction_result event and the transaction history.

• key destination avatar UUID
• integer amount number of L$, must be greater than zero, (amount > 0)

To run this function the script must request the PERMISSION_DEBIT permission with llRequestPermissions and it must be granted by the owner.

Caveats

Permissions
  • Do not depend upon the auto-grant status of permissions. Always use the run_time_permissions event.
  • If the script lacks the permission PERMISSION_DEBIT, the script will shout an error on DEBUG_CHANNEL and the operation fails (but the script continues to run).
  • If PERMISSION_DEBIT is granted by anyone other than the owner, then when the function is called an error will be shouted on DEBUG_CHANNEL.
  • Once the PERMISSION_DEBIT permission is granted there is no way to revoke it except from inside the script (for example, with a new llRequestPermissions call) or the script is reset or deleted.
  • An object cannot pay another object.
  • It is impossible for a script to tell if an llGiveMoney transaction succeeded or failed. Use llTransferLindenDollars instead.
  • Objects deeded to groups cannot give money (the permission cannot be granted).
  • Use is limited to 30 payments in a 30 second interval for all scripts owned by that resident on a region. Sustained overage will produce a script error and halt payments while the rate remains excessive. Historically, faster payments have failed intermittently.
  • Once a script has the PERMISSION_DEBIT permission it can empty an account of L$.
    • Fraud & theft are both Linden Lab violations and crimes. Misuse this function and you risk being banned and legal action. In addition LL may freeze the accounts of anyone the money is transferred to and restore it to it's rightful owners. This may involve retrieving it from third party exchanges and accounts on those exchanges being frozen. The system is not designed to be friendly towards fraud.

   string floatText = "I have no L$ to give away :(";
   if(giveAwayAmount <= currentStash)

// else

   //  I have no L$ to give away :(
   llSetText(floatText, <1.0, 1.0, 1.0>, (float)TRUE);
