Forum :: EOSERV :: Pet system [tutorial] (outdated)

that would be an awesome add on. please do release that. i wish i was good at programming.. i have awesome ideas but no skills to set them up. 

(sorry for going off topic)

I made my own topic about a problem I was having but after playing with it for a bit more i've found a couple of more things i'm not sure if it's because of how I put it or I miss things or if that's just how limited this script actually is but

    * Pets mess up on relog
    * Pets mess up when warping
    * Pets are affected by NPC walls

The NPC walls problem isn't that big of a deal and the warping isn't also. It's not that hard to just double click the egg again to re-spawn it. The only one that really seems to be a problem is the relog problem.

* Pets mess up on relog

Go to character.cpp and add the followed code on the Character::Logout()

Paste above the (this->online = false;)

UTIL_PTR_LIST_FOREACH(this->map->characters, Character, character)
    {
        if (this->InRange(*character))
        {
            this->pet->RemoveFromView(*character);
        }
    }
    erase_first(this->map->npcs, this->pet);
    this->pet->Release();
    this->has_pet = false;

* Pets mess up when warping

If you would go through the code a bit you would notice the (PetTransfer) at character.cpp that warps a pet on walking through a warp.

As you can see it transfers before entering and after entering;

this->player->character->PetTransfer();
                                this->player->character->Warp(Map, X, Y, WARP_ANIMATION_NONE);
                                this->player->character->PetTransfer();

Use those warps also in lets say scrolls;

At item.cpp Case scrolls

this->player->character->PetTransfer();
       this->player->character->Warp(item->scrollmap, item->scrollx, item->scrolly, WARP_ANIMATION_SCROLL);
       this->player->character->PetTransfer();

Warps a player pet with him on a use of a scroll.

* Pets are affected by NPC walls

At map.hpp check out this part;

bool Walkable(bool npc = false)
 {
  if (this->warp && npc)
  {
   return false;
  }

  switch (this->tilespec)
  {
   case Wall:
   case ChairDown:
   case ChairLeft:
   case ChairRight:
   case ChairUp:
   case ChairDownRight:
   case ChairUpLeft:
   case ChairAll:
   case Chest:
   case BankVault:
   case MapEdge:
   case Board1:
   case Board2:
   case Board3:
   case Board4:
   case Board5:
   case Board6:
   case Board7:
   case Board8:
   case Jukebox:
    return false;
   case NPCBoundary: // Hmmm...
    return !npc; // Hmmm....
   default:
    return true;
  }
 }

"Pineapples and shit."

Awesome everything is all fixed up. Thank you very much Ananas (:

I really don't wanna bug you but my pet seems to just stand there if the character is idle and I see where it says:

1. // Random walking
2.  
3.         int act;
4.         if (this->walk_idle_for == 0)

Yes after compiling and i click rebuild and i get this

||=== eoserv, SQLITE ===|

ld.exe||cannot find -lpthreadGC2|
||=== Build finished: 1 errors, 7 warnings ===|

EDIT2: are pets suppose to attack people? becouse mine doesent or are they there for looks?

EDIT: nevermind im dumb, i was missing some linker settings in the compiler and debugger works perfect, very nice

How do you get the pets to attack monsters

Hello everyone, I was wondering if someone could tell me what this means.

I downloaded the compiled version, just doesn't work the commands... #attack,#follow

and I dont know how to spawn a pet

With that compiled source there's a typo on the first line of the player command code,it will say this;

if (this->player->character->admin && message[0] == '#')

Just change the word "admin" to "player" and it should work fine.Also as Digitx said in the previous pages, the commands are;

$sp (name) (npcid) - Spawning pet

$dp (name) - Dismissing a Pet

ye, ty festa, it worked, but now the problem are : How to make a pet attack npcs / player and this command above, which was posted before on this topic :

if(id == ItemID)
                {
                    if(!this->player->character->has_pet)
                    {
                        this->player->character->has_pet = true;
                        unsigned char index = this->player->character->map->GenerateNPCIndex();
                        if (index > 250)
                        {
                            break;
                        }
                        if (this->player->character->PetCounter > 1)
                        {
                            break;
                        }
                        this->player->character->pet = new NPC(this->player->character->map, NpcID, this->player->character->x +1,this->player->character->y, 1, 1, index, true, true);
                        this->player->character->pet->SetOwner(this->player->character);
                        this->player->character->map->npcs.push_back(this->player->character->pet);
                        this->player->character->pet->Spawn();
                        this->player->character->PetCounter = 1;
                    }
                }

I got these errors :

If anyone wants to let characters spawn a pet by using an item place this in item.cpp

Under this..

               

                EIF_Data *item = this->server->world->eif->Get(id);
                reply.SetID(PACKET_ITEM, PACKET_REPLY);
                reply.AddChar(item->type);
                reply.AddShort(id);

Code:

if(id == ItemID)
                {
                    if(!this->player->character->has_pet)
                    {
                        this->player->character->has_pet = true;
                        unsigned char index = this->player->character->map->GenerateNPCIndex();
                        if (index > 250)
                        {
                            break;
                        }
                        if (this->player->character->PetCounter > 1)
                        {
                            break;
                        }
                       this->player->character->pet=newNPC(this->player->character->map,NpcID,this->player->character->x+1,this->player->character->y,1, 1, index, true, true);
                        this->player->character->pet->SetOwner(this->player->character);
                        this->player->character->map->npcs.push_back(this->player->character->pet);
                        this->player->character->pet->Spawn();
                        this->player->character->PetCounter = 1;
                    }
                }

Just replace NpcID / ItemID with the item / npc you wish to use.

Edit: Remove PetCounter if you don't want it.

This does not work, at all. Even after I put

#include npc.hpp

I tried modding this code in several different ways, but it just doesn't want to work. It compiles fine however, I can't seem to get my eggs to do anything.

Edit: tinkered with it, fixed it. put it where Jimbo said to put it. also make sure you 

Edit: Figured out how to get the item to stay after use(choppy but works)

#include npc.hpp

if(id == ItemID)

                {

                     this->player->character->Save(); //this may be unnessasary

                     this->player->character->AddItem(id, 1);//adds back the item after it's use

                     this->player->character->Save();

                    if(!this->player->character->has_pet)

                    {

                        unsigned char index = this->player->character->map->GenerateNPCIndex();

                        if (index > 250)

                        {

                        break;

                        }

                        this->player->character->pet = new NPC(this->player->character->map, NpcID, this->player->character->x + 1,this->player->character->y, 1, 1, index, true, true);

                        this->player->character->pet->Spawn();

                        this->player->character->pet->SetOwner(this->player->character);

                        this->player->character->has_pet = true;

                        //this->player->character->AddItem(682, 1);

                        this->player->character->map->npcs.push_back(this->player->character->pet);

                        this->player->character->Save();

                    }

                }

I set the item type as reward in the pub, with exp bonus of 0.

I edited your code to dismiss the pet if the item is used again, the pet can be summoned and dismissed as many times as needed by clicking the reward item. Now there's no need to type either command to summon or dismiss.

in "npc.cpp" ; 

#include "npc.hpp"

if (this->player->character->HasItem(id))
{
EIF_Data *item = this->server->world->eif->Get(id);
reply.SetID(PACKET_ITEM, PACKET_REPLY);
reply.AddChar(item->type);
reply.AddShort(id);

Add:

if(id == ItemID)
{


this->player->character->Save(); //this may be unnessasary
this->player->character->AddItem(id, 1);//adds back the item after it's use
this->player->character->Save();
