Item Sets (part 1)

this is Part one of a 2 part update. Part one is the examining of item sets ie.. bags, boxes, crates, of items that can be opened and the contents be added to you invntory. example veteran rewards and armour packs.

Part 2 will update and add code to actually open these items sets and receive your items.
Part 3 will be an update to allow for the selection of one item from the item set ie burynai plant, eggs
ItemSets.JPG
throughout the aritcle, if you update your code yourself and dont rely on svn updated code then you want the following changes, this is becuase of Jab's unability to alter the db due to a technical difficulty. its just a name change so Jab will have to keep references to the old names instead of new names i will be posting in the itemsdb.cpp
original name `item_unknown1` new name `item_stack_size`
original name `item_unknown2` new name `item_list_color`
this is the DB change

Code: Select all

ALTER TABLE `eq2world7`.`item_details_itemset`   
  CHANGE `item_unknown1` `item_stack_size` SMALLINT(5) UNSIGNED DEFAULT 0 NOT NULL,
  CHANGE `item_unknown2` `item_list_color` INT(10) DEFAULT 0 NOT NULL;
Items.h

add (yes its a duplicate number but armorsets use the same code #

Code: Select all

#define ITEM_TYPE_ITEMCRATE		  18
add

Code: Select all

vector<ItemSet*>		item_sets;
ItemSet_Info*			itemset_info;
to the section that starts with

Code: Select all

	#pragma pack()
	Item();
	Item(Item* in_item);
	~Item();
	string					lowername;
	string					name;
	string					description;
	int8					stack_count;
	int32					sell_price;



add the struct ItemSet below

Code: Select all

#pragma pack()
struct ItemStat{
	string					stat_name;
	int8					stat_type;
	sint16					stat_subtype;
	int16					stat_type_combined;
	float					value;
};
struct ItemSet{
	int32					item_id;
	int32					item_crc;
	int16					item_icon;
	int16					item_stack_size;
	int32					item_list_color;
	
};
struct Classifications{
	int32					class_id;  //classifications MJ
	string					class_name;
};
add this to the

Code: Select all

public:
	#pragma pack(1)
section

struct ItemSet_Info{
int32 item_id;
int32 item_crc;
int16 item_icon;
int32 item_stack_size;
int32 item_list_color;
};

add these 2 lines

Code: Select all

void AddSet(ItemSet* in_set);
void AddSet(int32 item_id, int32 item_crc, int16 item_icon, int32 item_stack_size, int32 item_unknown2);
into the section below

Code: Select all

void SetAppearance(int16 type, int8 red, int8 green, int8 blue, int8 highlight_red, int8 highlight_green, int8 highlight_blue);

FYI althought th e above code works as is, there are a couple changes coming to it to better it,
1. the item_list_color will be tweak. although this is the color of the item in the list, for the client, i haves discovered that its color should be devrived based on the level of the item compared to the the level of the player, and not just a hardcoded value,ie for most of these items in the list, if you are the correct level or above or, you are generally able to use the item its white. if you can not use it for some reason, ie level, class etc, it should be red
2. is the adjustment i forgot to make above when i figure it out

coming soon in part 2 will be unpacking the item crate (set)

Going through this code, I think you forgot a couple things.

Add to Items.h

Code: Select all

ItemSet_Info*        itemset_info;
vector<ItemSet*>        item_sets
Add to WorldDatabase.h

Code: Select all

int32    LoadItemsets();
