[Development] Trying Add Custom Monsters Or NPC

**Pinkof** · 28-11-12

Well i am trying add a custom monster or NPC.

Main 1.02r

Offsets:

00533800 CMP EAX,172 -> Here compare max monster support. if is eax>172 than mob transform in a Bull.

i recommend make a jmp before of cmp eax,172 for compare a new npc or mob.

in my case i use npc 479 Titus

i change offset JA xxxx to JA 006E7588 and there i put it.

[Development] Trying Add Custom Monsters Or NPC

For making it "talkable", NPC, make it gObj->Type = 3 from the GameServer.

i try but not work. =)

**[KeysS]** · 28-11-12

Nice work pink ^^ i made this time ago but i never get the usefull of this cuz i not code into gameserver for get new function or something XDD maybe just for add monsters and make a custom for new events :D

**Gembrid** · 28-11-12

there is a code that compares monster IDs and makes them act like NPCs.
you can either set bp on talk request packet(use regular NPCs) and analyze functions in call stack, or try to search code by regular NPCs IDs.

in old mains for adding NEW mobs(npcs) you will have to allocate more memory for models than main does, or you may have conflict problems, except for mobs(npcs) with player model, since it's already loaded =)

**-=DarkSim=-** · 28-11-12

Everything is much simpler:
1. Object attr (like NPC / Mob / None) stored in one struct in main, like OBJECTSTRUCT from server
2. Everything that is necessary - load model for monster id, other changes can make in struct

About you problem with talk:
- You need change attr for you new Object in struct, set param +722 (BYTE) == 4 (1 = Player, 2 = Monster, 4 = NPC)

Example with Elf Soldier:

Code:

// -> 515596 -> 1 Call
int gMakePreviewSoldierElf(int StructAddr) 
{
	Preview * gPreview = &*(Preview*)StructAddr;
	// ----
	gPreview->WingsSlot			= ITEM2(12, 3);
	// ----
	gPreview->HelmSlot			= ITEM2(7, 24);
	gPreview->HelmLevel			= 13;
	// ----
	gPreview->ArmorSlot			= ITEM2(8, 24);
	gPreview->ArmorLevel		= 13;
	// ----
	gPreview->PantsSlot			= ITEM2(9, 24);
	gPreview->PantsLevel		= 13;
	// ----
	gPreview->GlovesSlot		= ITEM2(10, 24);
	gPreview->GlovesLevel		= 13;
	// ----
	gPreview->BootsSlot			= ITEM2(11, 24);
	gPreview->BootsLevel		= 13;
	// ----
	gPreview->Action			= 11;
	gPreview->ModelScale		= 0x3F800000;
	gPreview->SelectZone		+= 70.0;
	// ----
	return gPreview->Unknown700;
}

In this function main set special attr for this NPC, like items, model scale, action, pk status and etc.

530802 ( int gObjSetAttr(Preview * gPreview, int ObjectID) )
- this function set Object attr from ID, you can use it, example:

Code:

if( ObjectID == 368 || ObjectID == 369 || ObjectID == 370 )
{
	*(BYTE *)(gPreview + 722) = 4; //-> Set NPC status to Object
}
if( ObjectID == 367
	|| ObjectID == 371
	|| ObjectID == 375
	|| ObjectID == 376
	|| ObjectID == 377
	|| ObjectID == 379
	|| ObjectID == 380
	|| ObjectID == 381
	|| ObjectID == 382
	|| ObjectID == 383
	|| ObjectID == 384
	|| ObjectID == 385

	|| ObjectID == 479
	|| ObjectID == 492
	|| ObjectID == 540
	|| ObjectID == 541
	|| ObjectID == 542
	|| ObjectID == 522
	|| ObjectID == 543
	|| ObjectID == 544
	|| ObjectID == 545
	|| ObjectID == 546

int gMakePreviewSoldierElf(int StructAddr) 
{    Preview * gPreview = &*(Preview*)StructAddr; 
   // ---- 
   gPreview->WingsSlot            = ITEM2(12, 3); 
   // ---- 
   gPreview->HelmSlot            = ITEM2(7, 24);    gPreview->HelmLevel            = 13; 
   // ---- 
   gPreview->ArmorSlot            = ITEM2(8, 24);    gPreview->ArmorLevel        = 13;
    // ---- 
   gPreview->PantsSlot            = ITEM2(9, 24);    gPreview->PantsLevel        = 13; 
   // ---- 
   gPreview->GlovesSlot        = ITEM2(10, 24);    gPreview->GlovesLevel        = 13; 
   // ----
    gPreview->BootsSlot            = ITEM2(11, 24);    gPreview->BootsLevel        = 13; 
   // ---- 
   gPreview->Action            = 11;    gPreview->ModelScale        = 0x3F800000;    gPreview->SelectZone        += 70.0; 
   // ---- 
   return gPreview->Unknown700;}

[C++] //Marlon: *(WORD*)(0x0051983A + 7) = ITEM2(7, 9); // -> First Weapon Slot - Pastebin.com

Main 1.03.25 (1.03Y+ JPN)

P.S.:
#define ITEM2(x, y) ((x * 512) + y + 834)

834 - Value only for 1.03.25, you need research it, you can calculate it value from model loader in any main

**caothuphutho** · 02-12-12

work 100% thank -=DarkSim=- very much :))
