Lindens in a box?

Some friends are getting married this weekend and I'd like to give them a nice little sum of $L as a starting-out wedding present.

Is there any way to script an object so that when its touched it will give an amount I previously specify? I'd like to put it in a nice gift-box type object. Of course, I only want it to give the amount once

Thank you oh benevolent scripters that make this crazy SL world go 'round!

This is quick and dirty and un-tested in-world, but should theoretically work. If the named recipient touches the object containing this script, it will pay them the amount specified, then self-delete.

integer AMOUNT = 0 ;	// Place the amount you want to give here!

string RECIPIENT = "" ;	// Place the name of the intended recipient here!

key owner ;

default
{
	state_entry()
	{
		owner = llGetOwner() ;
		llRequestPermissions( owner, PERMISSION_DEBIT ) ;
	}
	
	touch_start( integer num )
	{
		if( llDetectedName( 0 ) == RECIPIENT )
		{
			llGiveMoney( llDetectedKey( 0 ), AMOUNT ) ;
			llDie() ;
		}
	}
}

I imagine this script will fail if they take actually ownership of the object, or at the least they'll end up paying themselves.

Hmmmmmm a curious idea. Pituca Chang has some realllly cute gift boxes and bags that can only be opened by a designated recipient, but I think they can only give an object, not L$. I wonder though! Pituca?

it looked like your code was going to compare some ones name to thier key. Witch would fail. Unless llKey2Name was called. So I added that and a little error code. I haven't loged into sl yet so I can't test this.

//settings
integer AMOUNT = 0 ;	// Place the amount you want to give here!
string RECIPIENT = "" ;	// Place the name of the intended recipient here!
string message = "happy birthday!" // this message will be displayed when money is given
//dynamic do not edit values manually, they will be lost
key giverID = NULL_KEY;


key owner ;

default
{
	state_entry()
	{
		giverID = llGetOwner() ;
		llInstantMessage ( giverID, "would like to give  $" + (string)AMOUNT + "to /"" + RECIPIENT +"/" when they touch this object." );
		llRequestPermissions( owner, PERMISSION_DEBIT ) ;
	}
	
	touch_start( integer num )
	{
if ( llGetPermissions() & PERMISSION_DEBIT ) == PERMISSION_DEBIT) )
{
		key touchID = llDetectedName( 0 );
		if( llKey2Name ( touchID ) == RECIPIENT )
		{
			llGiveMoney( llDetectedKey( 0 ), AMOUNT );
			llSay ( 0, message );
			llSay ( 0, llKey2Name ( giverID ) + " has given $" + (string) AMOUNT + " to " + RECIPIENT + "." );
			AMOUNT = 0;
			llDie() ;
		}
		else if ( touchID ==  giverID )
		{
			llInstantMessage( touchID, " "+ (string) AMOUNT + " to '" + RECIPIENT + "'." );
		}
		else
		{
			llInstantMessage ( touchID, "I'm sorry this object is for /"" + RECIPIENT + "/" not /"" + llKey2Name ( touchID ) + "/"." ) ;
			llInstantMessage ( touchID, "if you think this is wrong contact the creator." ) ;
		}
}
else
{
llInstantMessage ( llGetOwner() , "woops permistion not set");
}
	}

	
}

You guys are the frikkin' coolest. Rawk.

(P.S. I will try tonight with a friend and a sequence of 1 $L until we figure out if it works or if I'm just silly. Or both.)

Note that llDie won't work if the object is attached. If your friend attaches it and keeps clicking, they will be able to debit your account indefinately.

Also, Kurt, you were incorrect in your statement about Cross's posted script, it compared the value in RECIPIANT (a name) to the value in llDetectedName(). Though the added permissions check in the touch_start event was a nice touch .

Here's my version:

// Constants / Settings:
string  MESSAGE   = "Happy Birthday from Inez!"; // Message for recipiant here.
string  RECIPIENT = "John Doe"; // Recipiant name here.
integer AMOUNT = 0; // Amount to give.
// Global variables:
key giver;

default {
	state_entry() {
		giver = llGetOwner();
		llInstantMessage(giver, "Please accept permission request before transferring this object.");
		llRequestPermissions(giver, PERMISSION_DEBIT);
	}
	
	run_time_permissions(integer perms) {
		if (perms & PERMISSION_DEBIT) {
			llInstantMessage(giver, "This object will give " + (string) AMOUNT 
			+ " to " + RECIPIENT + " when it is touched by " + RECIPIENT
			llInstantMessage(giver, "This object is ready to be transferred.");
		}
	}
	
	touch_start(integer touchers) {
		if (llDetectedName(0) == RECIPIENT) {
			if (llGetPermissions() & PERMISSION_DEBIT) {
				key recieverKey = llDetectedKey(0);
				llInstantMessage(recieverKey, MESSAGE);
				llInstantMessage(giver, (string) AMOUNT + " has been given to " + RECIPIENT);
				AMOUNT = 0;
				llRemoveInventory(llGetScriptName());
				llDie();
				state dead; // Just in case the above failed to kill script.
			}
		}
	}
}

state dead {
	state_entry() {
		llRemoveInventory(llGetScriptName());
		llDie();
		llSetTimerEvent(30);
	}
	
	timer() {
		llRemoveInventory(llGetScriptName());
		llDie();
	}
}

Oooh, good point, Chris! Hehe, this is why I'm a 'hack' and not a 'real scripter'.

I was assuming that the box was remaining in Inez ownership, which looking back, is kinda silly of me.

Have you guys tested this?

I don't think it will work, because a script can't have someone else's debit permissions.

As soon as your gift-box becomes owned by someone else, it loses your debit permissions. Of course, if you rez the gift-box (and you remain the owner), I think all of the posted scripts will work for you.

Cheers

Ditto on what Francis said. You will need to somehow communicate to an object you own and you have given debit permissions on to transfer cash.

Yeah, probably a better approach will be something that sends an inworld email to another object and tells it to pay the user.

I'd probably hardcode the keys of the avatars to get the money, but that's simply the paranoid programmer in me.

If you want to give it to the first person that touches the object, than you might want to md5 against a secret, but then you have to assume nobody can hack scripts.

Of course, all transfers are recorded so if someone does hack it they risk getting banned.

Or......

I could just quit trying to be so damn cutsie and give him the money outright


No, seriously, I really appreciate everyone's thoughts and efforts on this. If all else fails, I'm really learning a lot about scripting by reading through the code and then the comments about it. Maybe someday I can get to the level where I can make something DO something and not just have it sit around and look purty...and not have to rely on greater minds than my own to make something remotely functional....

thanks again guys!

You can always im me in game if you have any questions. I do tutoring too ^.^

Thanks Kurt! I just might take you up on that offer. I taught myself HTML/CSS but I understand that's the equivilent of scripting baby steps. I can fudge around existing scripts but writing from scratch always gets me befuddled. I'm willing to pay an hourly wage for lessons. Are you available on weekends? Aw never mind, I'll IM ya inworld.

I'm sorry, I had to:

Stop to sell Lindens in a box!

It may be worth mentioning that the attachment hack (and any re-entrancy issues -- don't know those details about scripting yet) can be avoided with a spin-lock/"mutex"/what-have-you.

Eg.

integer moneyGiven = FALSE;

...

if (they touched it && !moneyGiven)
{
   moneyGiven = TRUE; // this must precede the giving of the money
   llGiveMoney( ... );
   ...
}

Something like that ensures that in the worst case scenario, they will fail to receive the money (and they can IM you about the problem).

true, but if the script set the value to 0. Witch it dose, and it's the only thing that changes the value. Witch it is. Then they would have to get the script to restart. At witch point the script restarts, loosing it's permission. If they copy the object. The copy has the same issue.

Personally the idea of giving any one a script that has a permission of mine, like money give me the hebby geebys. I'd always go the e-mail route.

Gene - it's a bit more complex than that. Anone can reset a script they own, thus, clearing your flag / breaking the spinlock.
