case BUYITEM_MENU:
{
char BuyItem[100];
objmgr.CreateGossipMenuForPlayer(&Menu, pObject->GetGUID(), 1, Plr);
sprintf(BuyItem, "Enter Item Name [%u]", MORPH_COST/DIVIDER);
Menu->AddItem(ICON_WHEEL, BuyItem, BUYITEM_FUNCTION, 1);
Menu->SendTo(Plr);
}break;

case BUYITEM_FUNCTION:
{
QueryResult *BoughtItem = WorldDatabase.Query("Select `Entry` FROM Tiberium_Items where `Name` = '%s'", Code);

if(BoughtItem)
{
Field *Fields = BoughtItem->Fetch();
uint32 BoughtItem = Fields[0].GetUInt32();
Plr->GetItemInterface()->AddItemToFreeSlot(BoughtItem);
Plr->Gossip_Complete();
}
}break;

This is only a tad bit of my script i would rather not post all of it but i am getting this error

---------------------------------------------------------------------------------------------------------------------------------------

1>Compiling...
1>Warper.cpp
1>..\src\GossipScripts\Warper.cpp(142) : error C2664: 'ItemInterface::AddItemToFreeSlot' : cannot convert parameter 1 from 'uint32' to 'Item *'
1> Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast
---------------------------------------------------------------------------------------------------------------------------------------

I can't figure it out the function is to type the name of the item into a box and you get the item i got the idea from the aspire stones morpher but i failed like usual.


Im i'm pretty sure i am posting this in the C++ section if this is in EMu Server guides i apologize LOL

[Function]

Well, from the much I know, Just remember *item would point to the memory of the value of item and item* is the derefrencer which derfrences item

So if string* item = std::string s1 "Hey foo";

Then you went something like

cout << *item; /// It would display the memory value(512 or something more depends on your 32 bit or 64 bit OS) of std::string s1, if you had something more like this cout << item*; it Would display Hey foo; Remember item* and *item are two different things hopefully that may help you but seems you have a type conversion error, as if the pointer doesnt have a value to point to. Just some my info hope i could help!

Thx for the reply but can you or someone dumb it down so i can understand.

Look at this

uint32 BoughtItem = Fields[0].GetUInt32();

and see the specific error message

cannot convert parameter 1 from 'uint32' to 'Item *'

Seems like you assigned BoughtItem wrongly or Item is used in the wrong context or something (I am TERRIBLE at explaining things )
See if you can fix it

edit:

Conversion from integral type to pointer type requires reinterpret_cast

The Item* thing is a pointer while Boughtitem is an integer ( you have a type conversion error, as if the pointer doesnt have a value to point to. )

edit2:
Try re-reading what r00tk3y said, it makes sense after the first few times you read it.
