money

	Security Warning!
	When writing a vendor, Always (ALWAYS!) check the amount paid in your money() event. Preconfigured payment amounts from llSetPayPrice() are only a suggestion to the client. The client can still send L$0 or any positive integer. Never trust the client software to be secure. This is not important, of course, for a simple tipjar

Description

Event: money( key id, integer amount ){ ; }

20	Event ID
	Delay

Triggered when money is paid to the prim in the amount by id.

• key	id	–	who paid
• integer	amount	–	the amount paid

Specification

When money is paid to the prim, the money is given to the object's owner.
If the object is owned by or deeded to a group it is divvied up amongst the group members immediately (which is why groups can't grant PERMISSION_DEBIT). Only members of a role that has the "Accounting/Pay group liabilities and receive group dividends" attribute will receive money.
Don't forget to turn on the pay-behavior of the prims/objects involved.
The pay buttons should be configured in most applications where money is being transfered (llSetPayPrice), it makes paying money to the object easier.

Caveats

• This event cannot be triggered by a call to llGiveMoney because llGiveMoney cannot be used by one object to pay another object.
• Money cannot be paid to an attachment.

Examples

This example shows the simplest tip-jar and shows how little code is needed to receive unverified amounts of money. <lsl>

default {

   money(key id, integer amount)      // Some money has been received (and has been paid into the owner's account) 
   {
       // Thank the giver for their tip
       llInstantMessage(id, "Thanks for the L$"  + (string) amount + " tip!");
   }

} </lsl> Next level of tip jar, advising owner, keeping a running total, and with floating text to show status. <lsl> integer Total; string OwnerName;

default {

   on_rez( integer sparam )
   {
       llResetScript();
   }
   state_entry()
   {
       OwnerName = llKey2Name( llGetOwner() );
       llSetText( OwnerName + "'s Tip Jar.\nAny tips gratefully received!\nL$0 Donated so far", <.2, 1, .6>, 1);
   }

   money(key id, integer amount)
   {
       Total += amount;
       // Shortcut 'cheat' to avoid multiple casts when constructing a message including non-string items
       string str = (string) [OwnerName, "'s Tip Jar.\nPlease tip if you are so inclined!\nL$", amount, " Was donated last!\nL$", Total, " Donated so far" ];
       llSetText(str, <1,1,1>, 1);
       llInstantMessage(id,"Thanks for the tip!");
       llInstantMessage(llGetOwner(), llKey2Name(id) + " donated L$" + (string) amount );
   }

} </lsl> An elementary vendor with money validation and refund capability <lsl> // Give the first item in this object's inventory to anyone who pays the price

integer price = 10; // The price needed to purchase the item

default {

   state_entry()
   {
       // Turn off pay options so no money can be received until we are ready
       llSetPayPrice(PAY_HIDE, [PAY_HIDE ,PAY_HIDE, PAY_HIDE, PAY_HIDE]);
       // Request Debit Permissions from the owner so refunds can be given
       llRequestPermissions(llGetOwner(), PERMISSION_DEBIT);
   }
   on_rez(integer p)
   {
       llResetScript();                // Reset script on rezzing. Will thus register any change of owner.
   }
   money(key id, integer amount)        // Some money has been received and has gone to this object's owner
   {
       if (amount < price)
       {   // Customer has not paid enough
           llInstantMessage(id, "That's not enough money.");
           llGiveMoney(id, amount);   // Refund the money they paid
           return;
       }
       if (amount > price)
       {   // Customer paid too much. Refund the excess
           integer change = amount - price;
           llInstantMessage(id, "You paid more than L$" + (string)price
               + "  your change is L$" + (string)change );
           llGiveMoney(id, change);
       }
       // Customer has paid at least the right amount. Give them the item.
       string ItemName = llGetInventoryName(INVENTORY_OBJECT, 0);
       llGiveInventory(id, ItemName);
       llInstantMessage(id, "Please accept your purchase worth L$" + (string) price );
   }
   run_time_permissions(integer perm)
   {
       // If Debit permissions are granted, set up the pay price for this single-price vendor
       if(perm & PERMISSION_DEBIT)
           llSetPayPrice(price, [PAY_HIDE ,PAY_HIDE, PAY_HIDE, PAY_HIDE]);
   }
