[Help] Custom command .modify mirror or clone or whatever u like ;)

[yimgame]

Hey every body

Well i am not a specialist of C but i have a little princes of 5 years and she ask me if is possible to have a button to morph the player like the creature she have selected... and i think why not.

I was looking around the code and found usefull material in level2.cpp

//mirror (orignally is ModifyMorph + NpcSetModel
bool ChatHandler::HandleModifyMirrorCommand(const char* args)
{
   if (!*args)
       return false;

   CreatureInfo const* cInfo = creatureTarget->GetCreatureInfo(); //NpcSetModel originally recive a unit32 variable and modifymorph use a unit16 variable can this guive some problem ? Help!!!

   uint16 display_id = cInfo; // this is correct ? i can use the variable as is ? or need locate inside the variable the portion dedicated to displayid ? Help!!!

   Unit *target = getSelectedUnit();
   if (!target)
       target = m_session->GetPlayer();

   // check online security
   else if (target->GetTypeId() == TYPEID_PLAYER && HasLowerSecurity((Player*)target, 0))
       return false;

   target->SetDisplayId(display_id);

   return true;
}

I added the proper lines to chat.cpp and chat.h

Now is possible this work ?

I look in forum's about 15 pages returned by the search of modify morph and do not see anything like this.

Any help will be apreciate.

CreatureInfo const* cInfo = creatureTarget->GetCreatureInfo(); //NpcSetModel originally recive a unit32 variable and modifymorph use a unit16 variable can this guive some problem ? Help!!!

uint16 display_id = cInfo; // this is correct ? i can use the variable as is ? or need locate inside the variable the portion dedicated to displayid ? Help!!!

This will give you the pointer to cinfo.

From Creature.h:

struct CreatureInfo
{
...
   uint32  DisplayID_A[2];
   uint32  DisplayID_H[2];
...
};

You should try:

//mirror
bool ChatHandler::HandleModifyMirrorCommand(const char* args)
{
   Creature *pCreature = getSelectedCreature();

   if (!pCreature)
   {
       SendSysMessage("Please select a creature.");
       SetSentErrorMessage(true);
       return false;
   }
   CreatureInfo const* cInfo = pCreature->GetCreatureInfo();

   m_session->GetPlayer()->SetDisplayId(cInfo->DisplayID_A[0]);
   //To my knowledge in most scenarios DisplayID_A[0..1] and DisplayID_H[0..1] should be the same.

   return true;
}

Edit: this works perfectly on my server. Hope I could help!

Slurm you rock man this is wonderfull, many thanks really i dont see the problems. 1º i dont think in Null cose i dont ask for the existance of creature target and 2º i change the displayID to the same target i collected the info.

Thanks for the reply i will try to re compile a new core (i am recently new in nix is totally diferent compile in nix than win.)

Recompile :

make (-j2 if you have a dual core or -j4 if you have a quad)

make install (-j2/-j4)

That's it!
