slot[playerData.activeWeapon].valid() always returns false

Hi!

I have a problem with my game, because

Code:

slot[playerData.activeWeapon].valid()

always returns false.

Definition:

Code:

Reference<ItemEC> slot[SLOT_NUM];        //These are references to items which are placed at certain slots

And my Inventory::update function:

Code:

if(slot[playerData.activeWeapon].valid())

      if(OrientP *point = owner.cskel.findPoint("HandR"))

         slot[playerData.activeWeapon]().matrix(Matrix().setPosDir(point->pos, point->perp, point->dir));

I think that false is a correct "answer", but why it's not valid? When i pick up item, it's added to item container but not to the reference.

you must assign object to reference so it can become valid

slot[x]=object;

I have this code:

Code:

void Player::autoPickUp()

{

   if(!Kb.bp(KB_F)) return;

   Memc<Game::Obj*> obj;

   Vec test_pos = pos() - Vec(0, ctrl.height() / 2, 0);

   Game::World.objGet(obj, Ball(2, test_pos), OBJ_ITEM);

   REPA(obj)

   {

       if(ItemEC *item = CAST(ItemEC, obj[i]))

       {

         if(item->type2 == ITEM_WEAPON && item->mesh && Dist(test_pos, item->mesh->box * item->matrixScaled()) <= ctrl.radius() + 0.5f)

         {

             AddMessage(S + "Podniesiono " + item->name);

             Inv.slot[0] = *item;

             this->itemPickUp(*item);

         }

       }

   }

}

But it didn't works fine.

It works fine if I remove:

Code:

itemPickUp(*item)

from autopickup function.

But, when it's removed and I'm not holding weapon, it's drawing laying on a terrain.

this->itemPickUp(*item);

this changes memory address of 'item' object
you need to set 'slot' in virtual Chr::itemAdded

Ogniok · 03-23-2010 03:56 PM

I have this code:

Code:

void Player::itemAdded(Game::Item &item)

{

    if(ItemEC *actItem = CAST(ItemEC, item))

    {

            //Inv.slot[actItem->type + 1] = CAST(ItemEC, item); 

            Inv.slot[actItem->type + 1] = actItem;

    }

    Inv.itemAdded(item);

}

but when I try to compile my game i have an error:

Code:

1>d:\fps\player.cpp(112) : error C2682: cannot use 'dynamic_cast' to convert from 'EE::Game::Item' to 'ItemEC *'

**Esenthel** · 03-23-2010 03:59 PM

if(ItemEC *actItem = CAST(ItemEC, &item))

you're missing __super::itemAdded

It works fine now.

slot[playerData.activeWeapon].valid() always returns false
