[Solved] Problem when castin Element of an MemC when more than one inside

Hi,

Using Essenthel 2.0, I'm currently trying to handle NPCS with derived form my Chr class.

I suceed in doing so but it appears, as I store them into an MemC list, that I can't cast them when there is more than two element in my MemC memory. Client crash when using a cast function (cast valid but casted object is unfound/corrupted if I understant right what visual studio gives me during crash).

Details :

In the NPC class how I manage npc storage:

Code:

class NPC : Chr

{

[...]

}

Memc<NPC> npc;

On the game class, in init phase, where I create the NPC

Code:

npc.New().create("Human",Game.ObjParamsPtr(UID(1913893552, 1136375616, 2471945393, 4050012939)),666,Vec(-11.45, 0, 7.9)); //The first NPC

  npc.New().create("Warrior2",Game.ObjParamsPtr(UID(1500814990, 1298568280, 2465897402, 4149338710)),668,Vec(-12, 0, 7.9));//Second NPC spawned at his left

If I spawn only the first NPC, all work I can do with it everything I wish to do...

If I spawn both (or more) well it works until i need to cast one of these obj, like for example when I want to clic on them :

Code:

// move player

      if(Ms.bp(0) && Players.elms()) // on LMB pressed

         if(!Gui.ms() || Gui.ms()==Gui.desktop())

      {

         if(Cur.valid)

         {

            if(Cur.obj.valid())

            {                                                                       

             if(Chr *chr=CAST(Chr, &Cur.obj())) //This is where it crash, suceeding the cast but having trouble with values retrieved from it

              {

               Players[0].actionAttack(*chr);

              } 

            else

            {

               Players[0].actionMoveTo(Cur.pos);

            }

         }

      }

If I suppress all codes involving the cast on these npc I got no crash...
Below a screenshot : me on the left, my two npcs on the right... And the crash when my mouse is on them using the cast...

I tried to give you what I think are the crucial information to aprehend the problem whithout seeking in all the code I got but if more information or details are needed I'll give them happily.

Have a nice Day.

Hi,

Game objects need to be stored in constant memory address, therefore you should be using Memx instead of Memc.

However the recommended way is to use Game::ObjMemx containers as the tutorials present.

Ok then I'll try to correct it this night and see if working well (I'll post result).

Question about your answer: is it ok to use Map in this case or not ? Or maybe store it in Memx and then use a map of pointer ? In base code provided with EE2.0, Neighbors seems to be stored in map and not GameObjMemx (or maybe I was mislead in my code analysis).

Thx for the answer !

Ok so it's working well with MemX, right to the point thanks !
