transaction_result

Description

Event: transaction_result( key id, integer success, string data ){ ; }

34	Event ID
	Delay

Triggered when task receives asynchronous data

• key	id	–	matches the return of the llTransfer* function
• integer	success	–	TRUE if the transfer succeeded otherwise FALSE.
• string	data	–	On successful transactions this will contain a CSV of information pertaining to the transaction. In failure, a string will be returned matching one of the error tags below.

llTransfer* Function data CSV Contents	Error Tag (Returned from data)	Error Tag Description
key llTransferLindenDollars( key destination, integer amount ) [ key destination, integer amount ]	LINDENDOLLAR_INSUFFICIENTFUNDS	The source agent does not have enough L$ for the transfer
	LINDENDOLLAR_ENTITYDOESNOTEXIST	The destination UUID is not a valid agent.
	LINDENDOLLAR_BADCLOCKSKEW	There is bad clock skew between the sim host and the L$ service
	INVALID_DESTINATION	Destination agent is not a valid UUID
	INVALID_AMOUNT	Amount is <= 0
	THROTTLED	The scripted L$ throttle was hit for this object owner.
	MISSING_PERMISSION_DEBIT	The script does not have debit permission
	GROUP_OWNED	The object is group owned and thus can't give money
	TRANSFERS_DISABLED	L$ transfers are disabled in the region
	EXPIRED	The simulator timed out waiting for a response from the back-end service.
	SERVICE_ERROR	There was an error connecting to the back-end service
	LINDENDOLLAR_TRANSACTIONTIMEOUT	The transaction timed out.

Caveats

Examples

/*
* A simple piggy bank, anyone can pay in money and anyone can click it to get money out.
*
* TO DO:
*  - handle different errors differently based upon CSV output
*
* original by Strife Onizuka
*
* modified by Kireji Haiku:
*  - because weird things happen in LSL when using more than one state
*  - one should say thanks when being payed
*  - added 0 L$ payment when bank is empty, to show failed payment notifications
*  - added target UUID and L$ amount into transaction history, too
*
* Note from Traven Sachs (VWR-28201):
* In testing this script using an account with no funds - it has been noted that when the INSUFFICIENT FUNDS
* error occurs on Transaction Results that the Display of L$ on the account attempting to transfer funds will
* read as -1 on some viewers, even if the account has funds less than the transaction amount available to it.
* (i.e. if account has 7L and attempts to pay 10L the viewer display will read -1 L until the next L$ transaction
* occurs that is actually valid.  Don't know if this is a viewer glitch or back end glitch but felt it should
* be mentioned.)
