    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.

    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!!

    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).

    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

    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 .

    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

    Maybe, use SDKHooks_TakeDamage function.
