Block Wallhack v8 [CS & CZ]
 
2 Attachment(s)


Description:
This plugin blocks wallhacks (transparent walls) and soundhacks (squares, esps) including radar hacks by differently transmitting and filtering entity data.
It is advised to read everything about the plugin before asking questions! I will try to cover everything that you need to know here!
Also follow the instructions they are posted here for a reason!!!
If you ask a question that is already answered here your post will be ignored!





Features:
  • Player non visibility transfer block
    If the player does not see one of the points in the visibility plane of a player the player will not be transmitted therefore becoming invisible for transparent wall cheats.
  • Smooth engine
    The plugin adds prediction to player movement, it will make players not pop (appear out of nowhere).
  • FOV Check
    The plugins checks if the players are in front of us or not, if not the players will not be transmitted, it helps when we talk about CPU efficiency and also for cheats that show the player in 3rd person view.
  • Transparent entity detection and storage base
    It checks if we can see through an entity and it will modify it's properties so that the traces will not be influenced by it! The players will not notice anything!
  • Grenade and weapon transfer block
    The plugin will block entities like grenades and weapons when they are not seen.
  • ESP block
    The plugin will block soundhack and ESP by transmitting the sounds through different channels.
  • Footsteps generator
    The plugin will generate footsteps, if you want this remember to set mp_footsteps to 0!
  • Soundhack key
    The plugin will rename the sounds (the original sounds will not be deleted!) only if you want to this is optional! This helps when there are cheats that show the name of the sound on the screen, so that cheaters will not be able to understand what they mean.
  • Support for dynamic cameras
    The plugin will detect when a player uses a camera and will not affect the visibility.
  • New updated notifier
    The plugin will notify admins when an update is available!

Known bugs (cannot be fixed):
  • Player popping
    There is a risk that player pops out of nowhere, but the chance is small.
  • Player lag late appearance
    If the players have lag the plugin will make it even more difficult for them to play.
  • High ping sometimes [Problem seen on CSDM servers]
    Disable target check! If you are experiencing this problem!
  • Sounds sound different
    It is because of the different transmission. Don't worry about it!

Requirements:
  • Steam
  • AmxModX v1.80
  • EngineX
  • Orpheu




Installation:
  1. Download orpheu_base.zip from here, and unzip the archive in the "<target>/amxmodx" folder
  2. Unzip the file "cstrike" in the "<target>/cstrike" folder
  3. Add the plugin to plugins.ini.
  4. Enjoy!

Cvars:
  • // // TRW Block // //
  • trw_enable 1 // 1 (default/recommended) - plugin is turned on, 0 - off
  • trw_ignore_team 1 // 1 (default) if the plugin ignores teammates, 0 will check teammates and block them if not seen
  • trw_block_ents 0 // 3 block "grenade/armoury/weapon" entities with more checks, 2 block all entities but do more calculations on "grenade" entities, 1 block all entities that are not seen (no extra calculations), 0 (default) let the engine decide
  • trw_fov_check 1 // 1 (default/recommended) - do not transmit entities that are behind the player, 0 transmit everything
  • trw_target_check 1 // 1 (default) - if user shoots and hits someone that person will not be transmited, 0 disable tis check
  • trw_smooth_check 2 // 2 (default/recommended) - it will make the players not pop using vector calculations, 1 it will make players not pop using origin prediction, 0 disabled smooth check
  • trw_textureallow 1 // 1 (default/recommended) - will make the plugin ignore transparent entities, 0 disable this check
  • // // SND Block // //
  • snb_enable 1 // 1 (default/recommended) enable ESP sound blocking, 0 - disabled plugin
  • snb_footsteps 1 // 1 (default/recommended) make the plugin generate footsteps set mp_footsteps to 0!!!, 0 disabled
  • snb_shotover 1 // 1 (default/recommended) override shots, 0 disabled

Config files information:
  • wb_sndkey.cfg
    Location: <target>/cstrike/addons/amxmodx/data/
    This file only appears only if you want to use the soundhack key! The key can be imported from another file and can be managed with the server command wb_createsoundkey. If you have updated the plugin there is a chance that it will not be compatible with the last block wallhack version (depending on updates).
    If you get in the console some of these messages:
    [Block Wallhack] Soundhack key version load failure (Version read failure). Using default sounds!
    [Block Wallhack] Soundhack key version load failure (Number of sounds does not correspond). Using default sounds!
    That means you need to delete these files and folders manually in order to create a new soundkey:
    "addons/amxmodx/data/wb_sndkey.cfg"
    "sound/wallblocker/"
Soundhack key mamagement command:
amx_sndkeycfg <command> <target> -> creates the soundhack key!
This override commands will only work only if the present soundkey is loaded, if it is not loaded you will get an override error.

Here are the usage examples:
amx_sndkeycfg help - this will show you how to use the command
amx_sndkeycfg delete - this will delete the present soundkey (only if it was loaded)
amx_sndkeycfg create - this will delete the present soundkey (only if it was loaded) and create a new one
amx_sndkeycfg import <target> - this will import a soundkey from a file (will not override the present soundkey)
amx_sndkeycfg overimport <target> - this will import a soundkey from a file and delete the present one (only if it was loaded)

How to install the the same soundkey on multiple servers:
In the first server you type the command amx_sndkeycfg create in console to create a soundkey.
After you have done this go to the folder <target>/cstrike/addons/amxmodx/data and copy the file wb_sndkey.cfg.
After that paste that file in the same folder for other servers, the plugin should get the soundhack key automatically.

Plugin camera compatability!
Add this function after you have used attach_view() or EngFunc_SetView functions
PHP Code:
stock wb_setview(id, attachent)
{
    if (!cvar_exists("wallblocker_version") && !cvar_exists("trwb_version"))
        return 0
 
    callfunc_begin("fw_setview", cvar_exists("wallblocker_version") ? "block_wallhack.amxx" : "trblock.amxx")

Re: Block Wallhack
 
It seems you are only checking the 8 corners of the player's hitbox.
What about in complicated maps that the 4 corners may not be visible, but other parts are?
An example would be if a terrorist is standing on the vent ladder in cs_assault where his head is above the top and the feet are below the bottom, so all you can see is the stomach area.

Not only 8 it checks the user origin, and the points between the 8 border points and origin so in total 17 points.

Re: Block Wallhack
 
found two things you really should optimize :/
anyway, as long as you do not detect whether a player can see another one more accurately this plugin is worthless + did you check whether this plugin really blocks wallhacks? i doubt that it will block all hacks since there should be more than just 1 way of creating a wallhack :D

PHP Code:
// fail, pev_flags can only change during player think which makes caching this one in prethink much better that this...
// NEVER USE ADDTOFULLPACK WITHOUT CACHING AS MUCH DATA AS POSSIBLE!!!
if ( pev(ent, pev_flags) & FL_DUCKING )

// --------------------------

// fail again, creating a new var over and over again in your plugin? you should modify
// stocks you use since most only use variables initialized by "new", in this case you should use
// a static variable
new Float:fraction;

Re: Block Wallhack
 
You could use ExecuteHam(Ham_FVecVisible, this, const Float: origin[3]), then you wouldn't have to retrieve player eyes position.

Code:
BOOL CBaseEntity :: FVisible ( const Vector &vecOrigin )
{
        TraceResult tr;
        Vector                vecLookerOrigin;
       
        vecLookerOrigin = EyePosition();//look through the caller's 'eyes'

        UTIL_TraceLine(vecLookerOrigin, vecOrigin, ignore_monsters, ignore_glass, ENT(pev)/*pentIgnore*/, &tr);
       
        if (tr.flFraction != 1.0)
        {
                return FALSE;// Line of sight is not established
        }
        else
        {
                return TRUE;// line of sight is valid.
        }
}

Re: Block Wallhack
 
I had this idea also (and I think that it has also implemented in HLGuard) and the true is: it is almost impossible to make it right without a huge amount of calculations and probably that will make it laggy with many users. One particular point where calculations are missing is in checking if the player carried weapon is visible (what is out of the player's bounding box). That will easily damage the game. And, as Exolent said particular, entities or map, designs can make it behave bad.

Edit: I have an simple idea to you. Instead of shipping it as an anti-wallhack solution, you could make it usable when you perform an action. Example: you suspect that a player is cheating, enable it on him, and check if his performance hugely differs.

One thing about the code: In traceline you should "IGNORE_GLASS".

I tested it on a wallhack and it works. Even if user crouches. Will optimize these parts. I did it fast because I was tired.

}
Ok, will do!

Will see about that.

Edit: joaquimandrade thought about what you said and I won't do it unfortunately, that way it will stress up the admins too much, by leaving it the way it is it's light, and it does its job.
Made all the updates and made a small demonstration movie.

Thanks! It would be good if you can test with other wallhacks.

Re: Block Wallhack
 
How about those wallhacks that dont display models, but a small square where is player, and those that make all walls transparent, also how often are those problems stated in 1st post, once a round, once a map ?
