Inventory System (new.pwn) - Adain - 11.11.2017

Basic Inventory On Dialogs

Hello there! My previous tutorial was really awful, and I don't promise that this will be better. But I try to correct my mistakes as much as I can.

So, The reason why I DO NOT recommend u to use this code:

- It's absolutely on dialog, without any textdraw.
- This code is a bit outdated.

The reason why I DO recommend u to use this code:

- This code is very useful for absolutely new.pwn (For test, after that u can modify it or re-write on textdraws)
- Some dayz servers use this code


Tutorial contain:
- System of Registration/Login and Saving account by using Dini.
- System of Inventory
- System of Hunger and Thirst
- Screenshots
- Archive with Includes and Plugins

How do it look like

To all includes
PHP Code:
#include <a_samp> // Include Basic Samp Functions
#include <dini> // Our read/write (also u can use y_ini)
#include <streamer> // Use streamer instead of standard CreateObject (streamer for loot) 
After that make defines of our dialogs:
PHP Code:
#define DIALOG_REGISTER 1
#define DIALOG_LOGIN 2
#define MAX_HUNGER_AMOUNT 3000 // Hunger Stat
#define MAX_THIRST_AMOUNT 3600 // Thirsty Stat
#define COLOR_GREY 0xAFAFAFAA
#define Dialog_Inventory 3 // Inventory Dialog
#define Dialog_Choose 5 // Use/Drop/Info Dialog
#define Dialog_TakeInv 6 // 
To all news we need to add variables
PHP Code:
new total_vehicles_from_files=3000; // for our loot system (It will use LoadStaticVehiclesFromFile)
new backpack[MAX_PLAYERS];
new file[ 128 ]; // Using for our file ( format( file, sizeof( file ), "Users/%s.ini", GetName(playerid)); ) 
PHP Code:
#define MAX_OBJ 10000 // Max obj 
#define INVNUMBERS 6 // up this number to make more items
new PlayerAdminMassage[MAX_PLAYERS][INVNUMBERS];
new playermassagetoadmin[MAX_PLAYERS]; 
Add enum of PlayerInfo, and PlayerInv
PHP Code:
enum pInfo
{
    pPass, // Player Password
    pAdmin,
    pHungry, // Hunger stat
    pThirsty, // Thirst stat
    pPack, // Player Backpack
    pSlots // Player Slots in Inventory
}
new PlayerInfo[MAX_PLAYERS][pInfo];
enum wInfo //weapon slots info
{
    wSlot0,
    wSlot1,
    wSlot2,
    wSlot3,
    wSlot4,
    wSlot5,
    wSlot6,
    wSlot7,
    wSlot8,
    wSlot9,
    wSlot10,
    wSlot11,
    wSlot12,
}
new Weapon[500][wInfo];
enum dInvEnum
{
Float:ObjPos[3], // Object pos in map
    ObjID, // Object ID
    ObjData // Object data info for dialog_choose -> info
};
new PlayerInv[MAX_PLAYERS][INVNUMBERS]; // Use for giving player loot (for example PlayerInv[playerid][3] = 2; - we give player Bean Can x2 ) 
After that we need to create arrays which will include information about Name of items, object ID's, and what is it for (dialog_choose -> info)
PHP Code:
new InvNames[INVNUMBERS][] = // Names of items in inventory (I also recommend to write down object id near the name)
{ //2040 iao?iiu
    "Empty", //1581
    "Dry Food",//2663
    "Bean Can",//1666
    "Sprunk",//1546
    "Roast Meat",//1546
    "Alice Backpack"// 3026
};
new InvObjects[INVNUMBERS] = // When u'll drop items it will use this ID's.
{
    1581, //empty
    2663, //
    1666, //bean
    1546, //Sprunk
    2806, //meat
    //backpacks (for instance)
    3026
};
enum subinfo // Give information about items for example ( dialogmsgbox ) - Dry Food - Up your hunger stat
{
    iD_sub[64],//noaouy
    iD_text[256]//Iacaaiea
};
new InfoSub[INVNUMBERS][subinfo] = {
    {"Empty", "Empty."},
    {"Dry Food", "Up your hunger stat"},
    {"Bean Can", "Up your hunger stat"},
    {"Sprunk", "Up your thirsty stat"},
    {"Roast Meat", "Up your hunger stat"},
    {"Alice BackPack", "You have more slots for items (loot)"}
};
new dInvData[MAX_OBJ][dInvEnum]; 
Go to the end of your mode and put this stock

PHP Code:
stock GetName(playerid) // This stock more better than always use GetPlayerName
{
    new name[ 32 ]; // array which write down player nickname
    GetPlayerName(playerid, name, sizeof( name )); // Get player name

Hunger and Thirst System

Add to all forward

PHP Code:
forward ProcessAllPlayers(); // All player process
forward ProcessPlayerHunger(playerid); // Hunger
forward ProcessPlayerThirsty(playerid); // Thirst 
public OnPlayerGameModeInit

PHP Code:
SetTimer("ProcessAllPlayers",1000,1); // Timer with repeating every seconds 
Create this publics

PHP Code:
public ProcessPlayerHunger(playerid)
{
    PlayerInfo[ playerid ][ pHungry ]--; // every second -1 hunger stat
    if(PlayerInfo[ playerid ][ pHungry ] <= 0)// If player hunger stat <= 10 - kill player
    {
    SetPlayerHealth(playerid, -10);
    }
    return 1;
}
public ProcessPlayerThirsty(playerid)
{
    PlayerInfo[ playerid ][ pThirsty ]--; // every second -1 thirst stat
    if(PlayerInfo[ playerid ][ pThirsty ] <= -10) // If player thirst stat <= 10 - kill player

So, The reason why I DO NOT recommend u to use this code:

- It's absolutely on dialog, without any textdraw.
- This code is a bit outdated.
- This code is not written well.
So why release it?

Re: Inventory System (new.pwn) - Ponga - 12.11.2017

How can we add looting items?

Re: Inventory System (new.pwn) - Zeth - 12.11.2017

Deleting old thread because of negative comments and making a new one isn't a smart work boi!

Re: Inventory System (new.pwn) - Adain - 12.11.2017

Arthur Kane, because If you have played on different samp dayz server, it's the most popular inventory (on dialogs)
Debjit, I really don't care about negative comments, I make this tutorial for beginners, and this system is really useful. If u are not support my work, you can skip my threads.
Ponga ,if u want to add new items u need to do next steps (sry for my eng)

It will looks like that - https://imgur.com/a/ZDhLq

Find this
PHP Code:
#define INVNUMBERS 6 
and change from 6 to 7. Because if u are not change this it will cause multi-dimensional error

Find this
PHP Code:
new InvNames[INVNUMBERS][] =
{
    "Empty",
    "Dry Food",
    "Bean Can",
    "Sprunk",
    "Roast Meat",
    "Alice Backpack"
    'M4A1' // our new item
}; 
And after 'Alice Backpack create name of your item

Here you write the ID of Model(object) of item (In our case it's 356)
PHP Code:
new InvObjects[INVNUMBERS] =
{
    1581,
    2663,
    1666,
    1546,
    2806,
    3026,
    356 // Object ID of our M4A1
}; 
After this u need to create info about this item, find this lines in your code

PHP Code:
new InfoSub[INVNUMBERS][subinfo] = {
    {"Empty", "Empty."},
    //Еда и питье
    {"Dry Food", "Up your hunger stat"},
    {"Bean Can", "Up your hunger stat"},
    {"Sprunk", "Up your thirsty stat"},
    {"Roast Meat", "Up your hunger stat"},
    {"Alice BackPack", "You have more slots for items (loot)"},
    {"M4A1","Use for protect yourself"} // We add new info
}; 
Go to stock UseItem(playerid) and add the function of using this item

PHP Code:
if(itemid == 6)// m4a1
    {
        GivePlayerWeapon(playerid, 31, 500); // Give player m4a1
        PlayerInv[playerid][itemid]--; // Remove from inventory
        PlayerInfo[playerid][pSlots] --; // Remove 1 slot from inventory ('cause be use this item)
    } 


Re: Inventory System (new.pwn) - Eoussama - 12.11.2017

I discourage working with strings.

Re: Inventory System (new.pwn) - Janoz12 - 22.06.2018

And if I want to place an object directly on the ground for the user to look for it? that does not appear directly in the inventory but that you should look for it

Sorry to revive theme but I really need this system

Re: Inventory System (new.pwn) - CodeStyle175 - 22.06.2018

what is this thing?

Re: Inventory System (new.pwn) - Logic_ - 22.06.2018

A few critiques:

1. Use SQLite (Better than Dini and alternative to MySQL and INI file saving systems and NATIVE-LY implemented in SA-MP!!)
2. Use one array for all the object information and macros?

PHP Code:
#define        GetObjectName(%0)            \
            gObjects[%0][E_OBJECT_NAME]
#define        GetObjectModelID(%0)        \
            gObjects[%0][E_OBJECT_ID]
#define        GetObjectDescription(%0)    \
            gObjects[%0][E_OBJECT_DESCRIPTION]
enum E_OBJECTS {
    E_OBJECT_ID,
    E_OBJECT_NAME[10],
    E_OBEJCT_DESCRIPTION[100],
};
enum {
    OBJECT_M4A1,
};
new gObjects[][E_OBJECTS] = {
    {356,    "M4A1",        "The M4A1 is a fully automatic variant of the M4 carbine – a shorter and lighter variant of the M16."}
};
