About:

• Modern version of [L4D & L4D2] God Frames be Gone from AtomicStryker.
• Players will instantly take damage instead of being dealt damage after a delay like the old plugin.
• Reads the IsVulnerable function to detect god frames and overwrites.
• Plugin #100

Thanks:

• Lux - For the patch method suggestions.
• paul92 - For the request and testing.

Changes:

1.7 (26-Oct-2023)
    - Fixed errors if the "m_zombieClass" is out of range. Thanks to "chungocanh12" for reporting.

1.6 (29-Apr-2022)
    - Added cvar "l4d_god_frames_incapacitated" to control damage on Incapacitated players. Requested by "ZBzibing".
    - Changed cvar "l4d_god_frames_allow" to allow the value "2" which only enables the forward.
    - Changed forward "OnTakeDamage_Invulnerable" params to show the damage type.
    - Potentially fixed reviving players instantly being incapacitated. Thanks to "Eyal282" for reporting.

1.5 (10-May-2020)
    - Added better error log message when gamedata file is missing.
    - Extra checks to prevent "IsAllowedGameMode" throwing errors.
    - Fixed delay cvars being read wrong for: world, fire, common, witch, tank.
    - Various changes to tidy up code.

1.4 (01-Apr-2020)
    - Fixed "IsAllowedGameMode" from throwing errors when the "_tog" cvar was changed before MapStart.

1.3 (05-Feb-2020)
    - Moved forward creation to the correct place. Was rushed for demonstration.

1.2 (21-Jan-2020)
    - Fixed L4D1 not using IsInvulnerable function in OnTakeDamage. Thanks to "fbef0102" for reporting.
    - Thanks to Lux for various help. L4D1 now reads and sets the IsInvulnerable timer directly.
    - L4D1 gamedata update required.
    - L4D2 gamedata update required if updating from 1.0.

1.1.2 beta (13-Jan-2020)

    - Fixed not resetting delay timers OnMapEnd.

1.1 beta (13-Jan-2020)
    - Added a heap of new cvars to control damage for individual infected etc.
    - New gamedata required.

1.0 (01-Dec-2019)
    - Initial release.

Requirements:

• Extension: DHooks (Experimental dynamic detour support)

Installation:

DO NOT click 'Get Plugin' or it will fail to compile because this plugin requires DHooks!

1. Download the .smx file and put into your servers \addons\sourcemod\plugins folder.
2. Download the .txt gamedata file and put into your servers \addons\sourcemod\gamedata\ folder.

Updating from 1.5 or older:

• New cvars have been added: use the Cvar Configs Updater, or delete the old cvars config or manually add them.

I would request individual SI godframes control. I would like for hunter pounces to ignore the godframes while don't want double spitters to incap players on the fly.

Also congrats on hitting a 100 plugins!!

[Silvers]

Thanks!

I was hoping no one would ask that...

The problem is the games vulnerable function gets called from the middle of OnTakeDamage. Using OnTakeDamagePre hook might not give reliable data for the players actual damage since a bunch of stuff is calculated inside OnTakeDamage.

Either using a pre hook and patching the function when required, or dhooks to detect when the function is called instead of patching, and allow or disallowing the damage according to cvars in OnTakeDamagePost.

That would be the better option but requires dhooks (which is hopefully becoming standard for all servers anyway).

[Spirit_12]

Dhooks has been such a great extension I feel like it should be part of the base package now.

I also made a similar "godframe gone and control" plugin before(l4d1 support only),
have individual SI and received godframes control, based on
here: https://github.com/Attano/L4D2-Compe...mes_control.sp

and here: https://forums.alliedmods.net/showthread.php?t=127934

but since I'm not such good programer and can not find the l4d1 "CTerrorPlayer::InvulnerabilityTimer" signature offset,
I used a terrible method

Spoiler

PHP Code:

"Games"
{
    "left4dead"
    {
        "Offsets"
        {
            "CTerrorPlayer::InvulnerabilityTimer"
            {
                "windows"        "11924"
                "linux"        "11904"
            }
            "CTerrorPlayer::InvulnerabilityTimer"
            {
                "windows"        "???"
                "linux"        "???"
            }
        }
    }
} 


It checks affected Survivors health after 0.1s an attack hit them, and if it finds player health wasn't reduced, using SetEntityHealth to set player's hp according to the damage .

Really? So no credit to the actual attacker then...

yes.., infected player get 0 reward point, it's wired I know
that's why I am looking for better method to remove godframe for each player
It seems that your plugin removes all players' godframe at pluginstart()

That's the whole point of the plugin to just outright remove them.

You could however is Hook OnTakeDamage and control your own godframes.


reference to this "CTerrorPlayer::InvulnerabilityTimer"
Dunno if it's just me reading timers in l4d1 don't seem to read for me that much unlike l4d2
maybe I am just stupid

Thanks for tips
I probably know how to do that, I will try to modify that

Maybe, use SDKHooks_TakeDamage function.
