From 3d412a4b30a9f7c7f51ea6562e694315948bd3da Mon Sep 17 00:00:00 2001 From: boris Date: Wed, 28 Nov 2018 16:00:02 +1300 Subject: cleaned up in short, the cheat and loader are now separate solutions. unused stuff was moved into the legacy solution in case anyone wants to compile it or whatever. i can change this back if you want to. also, i configured the loader to compile in x64, and have separate build types for linux and win64 --- cheat/internal_rewrite/net_showfragments.cpp | 50 ++++++++++++++++++++++++++++ 1 file changed, 50 insertions(+) create mode 100644 cheat/internal_rewrite/net_showfragments.cpp (limited to 'cheat/internal_rewrite/net_showfragments.cpp') diff --git a/cheat/internal_rewrite/net_showfragments.cpp b/cheat/internal_rewrite/net_showfragments.cpp new file mode 100644 index 0000000..93e5db0 --- /dev/null +++ b/cheat/internal_rewrite/net_showfragments.cpp @@ -0,0 +1,50 @@ +#include "hooks.hpp" +#include "mem.hpp" +#include "context.hpp" + +// Index 13 is GetBool, GetInt and GetFloat are inlined by default. +int __fastcall hooks::net_showfragments_get_int( void* ecx_, void* edx_ ) { + static auto old_fn = g_csgo.m_netshowfragments->get_old_function< decltype( &net_showfragments_get_int ) >( 13 ); + + static auto ret_checkreceivinglist = pattern::first_code_match( g_csgo.m_engine.dll( ), xors( "FF 50 34 8B 1D ? ? ? ? 85 C0 74 16 FF B6" ), 0x3 ); + static auto ret_readsubchanneldata = pattern::first_code_match( g_csgo.m_engine.dll( ), xors( "FF 50 34 85 C0 74 12 53 FF 75 0C" ), 0x3 ); + + static auto last_fragment = 0; + static auto last_time = 0.f; + + stack_t stack( get_baseptr( ) ); + auto cl = g_csgo.m_global_state->get_client_state( ); + auto nc = cl->m_netchannel; + + auto nci = g_csgo.m_engine( )->GetNetChannelInfo( ); + + if ( nci && ( nci->GetLatency( 1 ) > 0.06f ) && g_ctx.m_local ) { + if ( stack.return_address( ) == ret_readsubchanneldata ) { + auto e = ( uint32_t* ) ( nc ); + auto data = &e [ 0x54 ]; + + auto fragment = data [ 0x43 ]; + + if ( fragment == last_fragment ) { + float delta = GetTickCount( ) * 0.001f - last_time; + + if ( delta <= std::max( nci->GetLatency( 1 ), 0.3f ) ) { + ( ( uint32_t* ) data ) [ 0x42 ] = 0; + last_time = GetTickCount( ) * 0.001f; + } + } + } + + if ( stack.return_address( ) == ret_checkreceivinglist ) { + auto e = ( uint32_t* ) ( nc ); + auto data = &e [ 0x54 ]; + + auto fragment = data [ 0x43 ]; + + last_fragment = fragment; + last_time = GetTickCount( ) * 0.001f; + } + } + + return old_fn( ecx_, 0 ); +} \ No newline at end of file -- cgit v1.2.3
