I want to add a hud to this add-on, that when the player look at the weapon to pick it up, show a hudmessage with the name of the weapon.

PHP Code:

#include <amxmodx>
#include <engine>
#include <hamsandwich>

public plugin_init()
{
    register_plugin("Weapon pick up", "1.04", "daedhelil");
}

public client_PreThink(id)
{
    if(!is_user_alive(id))
        return PLUGIN_CONTINUE;
    
    static oldbuttons;
    oldbuttons = get_user_oldbutton(id);
    
    if(oldbuttons & IN_USE)
        return PLUGIN_CONTINUE;
    
    static buttons;
    buttons = get_user_button(id);
    
    if((buttons & IN_USE))
    {
        new aimOrigin[3];
        get_user_origin(id, aimOrigin, 3);
        
        new entity = -1;
        
        while((entity = find_ent_by_class(entity, "weaponbox")))
        {
            new Float:min_weaponboxOrigin[3];
            entity_get_vector(entity, EV_VEC_absmin, min_weaponboxOrigin);
            
            new Float:max_weaponboxOrigin[3];
            entity_get_vector(entity, EV_VEC_absmax, max_weaponboxOrigin);
            
            new Float:playerOrigin[3];
            entity_get_vector(id, EV_VEC_origin, playerOrigin);

            if(distance < 100.0)
            {
