How to create unlocks in GunXP mod?

1-
First you need a sma of example. I am using this code:

PHP Code:

#include <amxmodx>
#include <fakemeta>
#include <hamsandwich>
#include <xs>
#include <gunxpmod>
#include <engine>
#include <cstrike>

new PLUGIN_NAME[]     = "Template of unlock"
new PLUGIN_AUTHOR[]     = "xBatista [Jezza for templete]"
new PLUGIN_VERSION[]     = "1.0"

new const WEAPON_V_MDL[] = "add your model here";
#define WEAPON_CSW CSW_ADD YOUR CSW like AK47
new const weapon_n[] = "weapon_Add your weapon like ak47";

const m_pPlayer    = 41;
const m_flPrimaryAttack = 46;

#define IsPlayer(%1)  ( 1 <= %1 <= g_maxplayers )

new g_hasZoom[33];

new damage_weapon, pCvarRof, weapon_recoil;
new g_maxplayers;    
new bool:g_Weapon[33]; 
new Float:cl_pushangle[33][3];
new szClip, szAmmo;

public plugin_init() 
{
    register_plugin(PLUGIN_NAME, PLUGIN_VERSION, PLUGIN_AUTHOR)
    register_gxm_item("Unlock Name", "Description", add number of xp that how much it will cost for unlock like 100)

    damage_weapon = register_cvar("gxm_damage_ak","1.5"); // damage multiplier
    pCvarRof = register_cvar( "ak_rof", "0.090" ); // weapon rof
    weapon_recoil = register_cvar( "ak_recoil", "0.8" ); // weapon recoil

    register_event("CurWeapon", "Event_CurWeapon", "be", "1=1");
    
    RegisterHam( Ham_Weapon_PrimaryAttack, weapon_n, "Fwd_AttackSpeedPost" , 1 );
    RegisterHam(Ham_Weapon_PrimaryAttack, weapon_n, "Fwd_AttackSpeedPre");

        RegisterHam( Ham_Item_Deploy , weapon_n, "Fwd_AttackSpeedPost", 1 );

    RegisterHam(Ham_TakeDamage, "player", "Ham_DamageWeapon");

    register_forward( FM_CmdStart, "Fwd_CmdStart" );

    g_maxplayers = get_maxplayers();
}
public gxm_item_enabled(id) 
{
    g_Weapon[id] = true;
}
public client_connect(id) 
{
    g_Weapon[id] = false;
}
public plugin_precache()  
{
    engfunc(EngFunc_PrecacheModel, WEAPON_V_MDL);
}

public Fwd_AttackSpeedPre(Ent)
{
    new id = pev(Ent,pev_owner);
    entity_get_vector( id, EV_VEC_punchangle, cl_pushangle[id]);
}
public Fwd_AttackSpeedPost( const Entity )
{
    static id ; id = get_pdata_cbase(Entity, m_pPlayer, 4)
    if (g_Weapon[id] && IsPlayer(id) )
    {
        set_pdata_float( Entity, m_flPrimaryAttack, get_pcvar_float( pCvarRof ), 4 );

        new Float:push[3];
        entity_get_vector( id, EV_VEC_punchangle, cl_pushangle[id]);
        xs_vec_sub( push, cl_pushangle[id], push);
        xs_vec_mul_scalar( push, get_pcvar_float( weapon_recoil ), push);
        xs_vec_add( push, cl_pushangle[id], push);
        entity_set_vector( id, EV_VEC_punchangle, push);
    }
}

public Ham_DamageWeapon(id, inflictor, attacker, Float:damage, damagebits) 
{
    if ( !IsPlayer(attacker) || !g_Weapon[attacker] )
            return HAM_IGNORED; 

    new weapon2 = get_user_weapon(attacker, _, _);
    if( weapon2 == WEAPON_CSW)
    {
        SetHamParamFloat(4, damage * get_pcvar_float(damage_weapon));
        return HAM_HANDLED;
    }

    return HAM_IGNORED;
}
public Event_CurWeapon(id) 
{
    if ( !g_Weapon[id] || !is_user_alive(id) )
    return PLUGIN_CONTINUE;

    new Gun = read_data(2) 

    if( Gun == WEAPON_CSW)
    {
        entity_set_string(id, EV_SZ_viewmodel, WEAPON_V_MDL)
    }

    return PLUGIN_CONTINUE;
}

public Fwd_CmdStart( id, uc_handle, seed )
{
    if( !is_user_alive( id ) || !g_Weapon[id] ) 
        return FMRES_IGNORED;

    if( ( get_uc( uc_handle, UC_Buttons ) & IN_ATTACK2 ) && !( pev( id, pev_oldbuttons ) & IN_ATTACK2 ) )
    {
        new szWeapID = get_user_weapon( id, szClip, szAmmo )

        if( szWeapID == WEAPON_CSW && !g_hasZoom[ id ])
        {
            g_hasZoom[ id ] = true
            cs_set_user_zoom( id, CS_SET_AUGSG552_ZOOM, 1 )
        }

        else 
        {    if( g_hasZoom[ id ] )
            {
                g_hasZoom[ id ] = false
                cs_set_user_zoom( id,  CS_RESET_ZOOM, 0 )
            }
        }

        return FMRES_HANDLED;
    }

    return FMRES_IGNORED;
} 


2- Complete the blanks, and add model ;)

P.S: You can try the unlock_scout below in attachments ;) also find your own model
