What Is It?
It's an easy to use function-adding include to implement inventory for players.
Functions
Required
InventoryOnDialogResponse(playerid, dialogid, response, inputtext[])
This goes under OnDialogResponse for it to work properly
Non-Required
AddItem(playerid,ItemName[],Amount)
This gives the player the specified item and amount.
Returns 1 if successfull, returns 0 if player inventory is full. -- You can increase the MAX_ITEMS in the include.
RemoveItem(playerid,ItemName[],Amount)
This removes the specified item and amount.
Returns 1 if successful, returns 0 if player doesn't have the item.
PlayerHasItem(playerid,ItemName[])
This tells you if a player has an item
returns the amount of the item that the player has
GetPlayerItemInfo(playerid,&idx,const ItemName[],len=sizeof(ItemName),&Amount)
Gives you the information pertaining to a single players inventory, much like GetPlayerWeaponData
returns 1 unless &idx reaches a number larger than MAX_ITEMS
ResetPlayerInventory(playerid)
Removes all of a player's inventory
Doesn't return a number.
ShowInventory(playerid)
Shows the inventory dialog for that player. -- This uses my dialog method so it only uses 1 dialog id throughout the entire script, which is modifiable inside the include.
Doesn't return a number
Version 2
SaveInventory(playerid)
Saves the players inventory to "../scriptfiles/Inventory/NAME.inv" so don't forget to create the folder before using
Doesn't return a number
LoadInventory(playerid)
Loads the player's inventory if it exists
Returns 1 if successful, 0 if the file doesn't exist.
Callbacks
OnPlayerUseItem(playerid,ItemName[])
This is called once a player uses an item in the inventory window.
