Remove NPC/Item without targetting?

[Mindless Automaton]

Lets say I make a gump menu with with options:

brownhorse ON [OFF]

When I'd click ON, it'd do something like this:
http://www.uox3.org/jsdocs/characterm.html#SpawnNPC

My question is, when I click OFF (maybe days later), how do I get rid of that particular brownhorse assuming other unrelated brownhorses exist?

I was thinking something like storing the serial when the horse is spawned and deleting it by the serial?

Thanks!

That's the way. You can save a character's serial using for instance:

Code: Select all

myObject.SetTag( "BrownHorseSerial", ( myBrownHorse.serial & 0x00FFFFFF ) );

then retrieve it later using

Code: Select all

var myBrownHorse = CalcCharFromSer( myObject.GetTag( "BrownHorseSerial" ) );

and then optionally delete it by using

Code: Select all

myBrownHorse.Delete();

myObject can be a character or an item (you need to save the tag somewhere).

So far then:

Code: Select all

// Quest Command 
// Script no: 3014

function CommandRegistration()
{
	RegisterCommand( "quest", 2, true ); //Talk to a targeted character or item
}

function command_QUEST( pSock, execString )
{
	var pUser = pSock.currentChar;
	var myGump = new Gump; // create a new gump
	myGump.AddBackground( 0, 0, 300, 300, 2600 ); // add an automic scaled background
	myGump.AddButton( 300, 5, 0xa50, 1, 0, 0);  // Add a close-gump button
	myGump.AddPicture( 20, 40, 0x12D8 ); // add tile art
	myGump.AddText( 85, 135, 5, "Activate!" ); // add text, gets assigned TextID 0
	myGump.AddText( 85, 165, 7, "Deactivate!" ); // add text, gets assigned TextID 1
	myGump.AddRadio( 50, 130, 2152, 0, 0 ); //RadioButton with ID 0
	myGump.AddRadio( 50, 160, 2152, 0, 1 ); //RadioButton with ID 1
	myGump.AddButton( 160, 265, 0xF7, 1, 0, 1 ); // add the "okay" button
	myGump.Send( pUser.socket ); // send this gump to client now
	myGump.Free(); // clear this gump from uox-memory
	return false;
}


function onGumpPress( pSock, pButton, gumpData )
{
	var pUser = pSock.currentChar;
	
	switch(pButton)
	{
		case 0:
			// abort and do nothing
			break;
		case 1:
			var OtherButton = gumpData.getButton(0);
			switch(OtherButton)
			{ 
				case 0:
					nSpawned = SpawnNPC( "brownhorse", pUser.x, pUser.y, pUser.z, pUser.worldnumber );  //add this npc
					if( nSpawned != null )
					nSpawned.SetTag( "nSpawnedSerial", ( nSpawned.serial & 0x00FFFFFF ) ); //get the serial number for the npc
					pUser.SysMessage( "Wheee - a brown horse just spawned at my location!" ); //confirm
					break;
					
				case 1:
					var nSpawnedObj = CalcCharFromSer( nSpawned.GetTag( "nSpawnedSerial" ) ); //figure out the serial number
					nSpawnedObj.Delete();  // delete the npc
					pUser.SysMessage( "Wheee - a brown horse is deleted!" );  //confirm
					break;

			}
			break;
	}
}

Is there a property index for gumps? I am not sure what the property is for a pressed button. Is it something like OtherButton.pressed or .value?

Ultimately I'd like to have a few quests set up and be able to enable/disable them with the gump.

Thanks

Code: Select all

nSpawned.SetTag( "nSpawnedSerial", ( nSpawned.serial & 0x00FFFFFF ) ); 

Storing the serial of the horse on the horse doesn't make any sense. Store it on the char that created/requestet the horse.

Code: Select all

            case 1:
               var nSpawnedObj = CalcCharFromSer( nSpawned.GetTag( "nSpawnedSerial" ) ); //figure out the serial number
               nSpawnedObj.Delete();  // delete the npc
               pUser.SysMessage( "Wheee - a brown horse is deleted!"

nSpawned doesn't exist if case 1 is run, as it is only created in case 0. Again, store and read the serial from the char that used the gump.
You should also make shure you have a valid object before trying to perform any operations on them, like Delete().

Again, store and read the serial from the char that used the gump.

Ok, what about if you have GM#1 online & he creates the horse and then leaves. Later, GM#2 comes online and uses the menu to destroy the horse. I was assuming it wouldn't happen if the serial was stored on GM#1 since he left the game. Of course I'm assuming GM#2 could come on and nuke the horse as I haven't tested it that far yet.

Thanks!
