[aron9forever]

yeah I haven't really done this, I just took my code for removing bomb sites, hostage rescue sites and so on and implemented func_buyzone into it

I still think status icon is the best way

[yokomo]

To completely block buy i already did it by Orpheu, but i need to remove that silly buyzone icon.

I found a code by jim_yang:

  //patch StatusIcon "buyzone" color green from 160 to 0
  patch_mem_data<int>(GETREALADDR(0x535FE), 0);
  patch_mem_data<int>(GETREALADDR(0x618D4), 0);
  patch_mem_data<int>(GETREALADDR(0x619C1), 0);

Not sure signature work or not in current hlds, i'm using 5787 Linux.

info_map_parameters
buying "3"

Spawn this in plugin_precache, see if it works.
If it is then it is the most effective way

[Arkshine]

Basically, StatusIcon with "buyzone" is checkd/updated in CBasePlayer::HandleSignals, which is called each 0.5 second from CBasePlayer::UpdateClientData (by the way, using a member m_tmHandleSignals).

If you don't have a buy zone (func_buyzone entity), game will check if you are in a range (< 200u) of a spawn point.

Best way to hide the icon without too much code is probably to spawn a func_buyzone entity (if not already) and to set its origin to high place, or make entity not solid so you can't touch and trigger a buy signal.

To block buying, info_map_parameters is the easy and fast way but you will get a message. If you're using 1.8.3, you can use CS_OnBuyAttempt forward and returning PLUGIN_HANDLED.

Nice! it works..

Code

PHP Code:

#include <amxmodx>
#include <engine>

new const szClassnameBuy[] = "func_buyzone"

public plugin_precache()
{
    register_plugin("Hide Buyzone", "0.0.1", "wbyokomo")
    
    if(!IsFuncBuyZoneExist())
    {
        new ent = create_entity(szClassnameBuy)
        if(ent != -1)
        {
            log_amx("func_buyzone created: %d", ent)
            entity_set_origin(ent, Float:{8192.0,8192.0,8192.0})
            entity_set_int(ent, EV_INT_solid, SOLID_NOT)
            log_amx("func_buyzone hided: %d", ent)
        }
    }
}

IsFuncBuyZoneExist()
{
    new ent, yes = 0
    while((ent = find_ent_by_class(ent, szClassnameBuy)) != 0)
    {
        yes = 1
        log_amx("func_buyzone found: [%d]", ent)
        entity_set_origin(ent, Float:{8192.0,8192.0,8192.0})
        entity_set_int(ent, EV_INT_solid, SOLID_NOT)
        log_amx("func_buyzone hided: %d", ent)
    }
    return yes;
}

Reason? does func_buyzone only created once in a map? If more than 1 then i don't need to add "break".

[Arkshine]

That's the idea yokomo, though I don't like duplicated code, and I think this should be a better place to do this in plugin_init to make sure map entity is spawned.

Probably something like:

Spoiler

#include <amxmodx>
#include <engine>

public plugin_init()
{
    hideBuyIcon();
}

hideBuyIcon()
{
    new const buyzoneClassname[] = "func_buyzone";
    
    new entitiesList[16];
    new entitiesCount = find_sphere_class(get_maxplayers() + 1, buyzoneClassname, 4096.0, entitiesList, sizeof entitiesList);
    
    if (!entitiesCount)
    {
        entitiesList[0] = create_entity(buyzoneClassname);
        entitiesCount = 1;
    }
    
    for (new i = 0, entity; i < entitiesCount; entity = entitiesList[i], ++i)  
    {
        entity_set_origin(entity, Float:{8192.0, 8192.0, 8192.0});
        entity_set_int(entity, EV_INT_solid, SOLID_NOT);        
    }
}

or maybe like this to avoid to hardcode:

Spoiler

hideBuyIcon()
{
    new const buyzoneClassname[] = "func_buyzone";
    
    new Array:entitiesList = ArrayCreate();
    new entitiesCount, entity;
    
    while ((entity = find_ent_by_class(entity, buyzoneClassname)) > 0)
    {
        ArrayPushCell(entitiesList, entity);
    }
    
    if ((entitiesCount = ArraySize(entitiesList)) <= 0)
    {
        ArrayPushCell(entitiesList, create_entity(buyzoneClassname));
        entitiesCount = 1;
    }

    for (new i = 0, entity; i < entitiesCount; entity = ArrayGetCell(entitiesList, i++))  
    {
        entity_set_origin(entity, Float:{8192.0, 8192.0, 8192.0});
        entity_set_int(entity, EV_INT_solid, SOLID_NOT);        
    }
    
    ArrayDestroy(entitiesList);
}

Actually you could remove any "func_buyzone" and then creating one. The less entities, the better probably.

Spoiler

hideBuyIcon()
{
    new const buyzoneClassname[] = "func_buyzone";
    
    remove_entity_name(buyzoneClassname);
    
    new entity = create_entity(buyzoneClassname);
    entity_set_origin(entity, Float:{8192.0, 8192.0, 8192.0});
    entity_set_int(entity, EV_INT_solid, SOLID_NOT);
}

Hey Arkshine, how can I remove/hide the money and the round timer with this method ?
