Updated Flyen's EXP Tutorial (Fixed Errors)

Post by Archive-Poster »

Hey guys, I read through Flyen's thread about his old EXP tutorial, seen that a LOT of people were having trouble and not understanding why they were getting errors... WELL, I'll post a working tutorial.

First: Include Your Modules

Code: Select all

#include <amxmodx>
#include <amxmisc>
#include <nvault>
Then Define your classes, simply like this

Code: Select all

#define MAXCLASSES 5
Now we have to create the EXP, Levels, and Class Variables.

Code: Select all

new PlayerXP,PlayerLevel,PlayerClass[33]
//These are for your special kills
new XP_Kill,XP_Knife,XP_Hs
//This is for the vault, so your EXP saves to the server
new g_vault
This is where your Maxclasses comes in

Code: Select all

new const CLASSES[MAXCLASSES][] {
             "None",
             "Rifle Specialist",
             "Sniper Specialist",
             "Pistol Specialist",
             "Machine Gun Specialist"
}
Now we will make the Levels with the Exp you desire

Code: Select all

new const LEVELS[10] = {
             "100",
             "200",
             "400",
             "800",
             "1600",
             "3200",
             "6400",
             "12800",
             "25600",
             "51200"
}
Now we create the plugin_init

Code: Select all

public plugin_init()
{
          register_plugin("Simple EXP Mod", "1.0", "Thelius") // Registers the Plugin to the ModName, Version, and Creator
          register_event("DeathMsg", "eDeath", "a") // This is the death event
          SaveXP = register_cvar("SaveXP", "1") // This is to make sure that Saving XP is enabled
          XP_Kill = register_cvar("XP_per_kill", "40") // This defines the amount of EXP you gain per kill
          XP_Hs = register_cvar("XP_hs_bonus", "50") // This defines the amount of exp gained per headshot
          XP_Knife = register_cvar("XP_knife_bonus", "20") // This defines the amount of Exp gained per Knife Kill
          g_vault = nvault_open("XPMod") // This opens the nvault so it can save the exp

          register_clcmd("say /class", "ChangeClass") // Saying /class will open the class menu
          register_clcmd("say_team /class", "ChangeClass") // Team saying /class will open the class menu
          register_clcmd("say /xp", "ShowHud") // Saying /xp will show your EXP
          register_clcmd("say_team /xp", "ShowHud") // Team Saying /xp will show your EXP
}
Now we create the Death event, so it will keep your levels and exp, remember we called it eDeath, Let's begin.

Code: Select all

public eDeath( )
{
        new headshot,attacker = read_data( 1 )
        new weapon = get_user_weapon(attacker,headshot,headshot)
        headshot = read_data( 3 )

        PlayerXP[attacker] += get_pcvar_num(XP_Kill)

        if(PlayerClass[attacker] == 0)

        if(headshot)
        PlayerXP[attacker] += get_pcvar_num(XP_Hs)

        if(weapon == CSW_KNIFE)
        PlayerXP[attacker] += get_pcvar_num(XP_Knife)

        while(PlayerXP[attacker] >= LEVELS[PlayerLevel[attacker]])
        {
                      client_print(attacker, print_chat, "[XP Mod] Congratulations you are now level %i %s!");
                      PlayerLevel[attacker] += 1
         }
         ShowHud(attacker)
         SaveData(attacker)
}
We set the Hud to show the EXP and all that fun stuff

Code: Select all

public ShowHud(id)
{
            set_hudmessage(0, 255, 0, 0.28, 0.88, 0, 6.0, 12.0)
            show_hudmessage(id, "Level: %i^nXP: %i^nClass: %s", PlayerLevel[id],PlayerXP[id],CLASSES[PlayerClass[id]])
}
Now we create the Change Class Menu

Code: Select all

public ChangeClass(id)
{
        new menu = menu_create("Class Menu", "Class_Handle");
        
        menu_additem(menu ,"Rifle Specialist", "1" , 0);
        menu_additem(menu ,"Sniper Specialist", "2" , 0);
        menu_additem(menu ,"Pistol Specialist", "3" , 0);
        menu_additem(menu ,"Machine Gun Specialist", "4" , 0);

        menu_setprop(menu , MPROP_EXIT , MEXIT_ALL);

        menu_display(id , menu , 0);

        return PLUGIN_CONTINUE;
}
Now we create the Menu Handler for the Class Menu

Code: Select all

public Class_Handle(id , menu , item)
{
         if(item == MENU_EXIT)
         {

                       menu_destroy(menu);
         }

         new szCommand[6], szName[64];
         new access , callback;

         menu_item_getinfo(menu , item , access , szCommand , 5 , szName , 63 , callback);

         new i = str_to_num(szCommand)
         if(PlayerClass[id] != i)
         {
                    PlayerClass[id] = i
                    client_print(id,print_chat, "[XP Mod] You are now a %s", CLASSES[i])
         }
         else
         {
                    client_print(id,print_chat, "[XP Mod] You are already a %s",CLASSES[i]
         }

         menu_destroy(menu);
         return PLUGIN_CONTINUE
}
Now we set the Exp to load on someone who joins and has saved EXP

Code: Select all

public client_connect(id)
{
         if(get_pcvar_num(SaveXP) == 1)
         {

                  LoadData(id)
         }
}
Now we set the Exp To save on someone who disconnects from the server

Code: Select all

public client_disconnect(id)
{
         if(get_pcvar_num(SaveXP) == 1)
         {
         
                  SaveData(id)
         }
         PlayerXP[id] = 0
         PlayerLevel[id] = 0
         PlayerClass[id] = 0
}
Now we set the exp to save to the Clients steam id

Code: Select all

public SaveData(id)
{
         new AuthID[35]
         get_user_authid(id,AuthID,34)

         new vaultkey[64],vaultdata[256]
         format(vaultkey,63,"%s-Mod", AuthID)
         format(vaultdata,255,"%i#%i#",PlayerXP[id],PlayerLevel[id])
         nvault_set(g_vault,vaultkey,vaultdata)
         return PLUGIN_CONTINUE
}
Now we set it to Load the Clients Exp Based on his Steam ID

Code: Select all

public LoadData(id)
{
         new AuthID[35]
         get_user_authid(id,AuthID,34)

         new vaultkey[64],vaultdata[256]
         format(vaultkey,63,"%s-Mod",AuthID)
         format(vaultdata,255,"%i#%i#",PlayerXP[id],PlayerLevel[id])
         nvault_get(g_vault,vaultkey,vaultdata,255)

         replace_all(vaultdata, 255, "#", " ")

         new playerxp[32], playerlevel[32]

         parse(vaultdata, playerxp, 31, playerlevel, 31)

         PlayerXP[id] = str_to_num(playerxp)
         PlayerLevel[id] = str_to_num(playerlevel)

         return PLUGIN_CONTINUE
}
And we're Finished

This is what it looks like all together

Code: Select all

#include <amxmodx>
#include <amxmisc>
#include <nvault>

new PlayerXP,PlayerLevel,PlayerClass[33]
//These are for your special kills
new XP_Kill,XP_Knife,XP_Hs
//This is for the vault, so your EXP saves to the server
new g_vault

             "None",
             "Rifle Specialist",

          XP_Kill = register_cvar("XP_per_kill", "40") // This defines the amount of EXP you gain per kill
          XP_Hs = register_cvar("XP_hs_bonus", "50") // This defines the amount of exp gained per headshot
          XP_Knife = register_cvar("XP_knife_bonus", "20") // This defines the amount of Exp gained per Knife Kill
          g_vault = nvault_open("XPMod") // This opens the nvault so it can save the exp

          register_clcmd("say /class", "ChangeClass") // Saying /class will open the class menu
          register_clcmd("say_team /class", "ChangeClass") // Team saying /class will open the class menu
          register_clcmd("say /xp", "ShowHud") // Saying /xp will show your EXP

}

        new headshot,attacker = read_data( 1 )
        new weapon = get_user_weapon(attacker,headshot,headshot)
        headshot = read_data( 3 )

         }
         ShowHud(attacker)
         SaveData(attacker)
}

public ShowHud(id)

            set_hudmessage(0, 255, 0, 0.28, 0.88, 0, 6.0, 12.0)

}
To add HP every 5 levels or however you want it. simply do all these things :P

Code: Select all

#include <fun> // Not sure if this is needed or not, but couldn't get mine to work without.
#include <fakemeta> // Will use for a future update, already used, just trying to get someone to help me with testing.

public plugin_init()
//[....]

        register_event("ResetHUD", "on_spawn", "be")

//[....]
}
YOU WILL NEED TO CREATE THIS WITHIN THE .SMA THIS IS NOT IN THE ORIGINAL!

Code: Select all

public on_spawn(id)
{
       if (PlayerLevel[id] <= 5) // The number 5 Decides which levels are included, and Hopefully you know simple math to know what the <= means..
       {
               set_user_health(id, 150);
        }
}
