Tried to hook CLagCompensationManager::StartLagCompensation https://github.com/ValveSoftware/source ... n.cpp#L328
Problems with it game crash and ESP not present output in the console when the function was called.

Syntax: Select all

start_lag_compensation = server_binary[b'\x55\x8B\xEC\x83\xE4\xF8\x83\xEC\x48\x56\x8B\xF1\xC7\x44\x24\x48\x00\x00\x00\x00'].make_function(
    Convention.THISCALL,
    (DataType.POINTER, DataType.POINTER, DataType.POINTER),
    DataType.VOID
)

Tried to hook FX_FireBullets https://github.com/ValveSoftware/source ... d.cpp#L108
Problems with it game crash when the function was called.

    Convention.CDECL,
    (DataType.INT, DataType.POINTER, DataType.POINTER, DataType.INT, DataType.INT, DataType.INT, DataType.FLOAT),
    DataType.VOID

Could you please post the full test code, so tests can be done using exactly the same code and doesn't require us to complement your snippets?

Syntax: Select all

from memory import find_binary
from memory import Convention
from memory import DataType
from memory.hooks import PreHook

server_binary = find_binary('server')

start_lag_compensation = server_binary[b'\x55\x8B\xEC\x83\xE4\xF8\x83\xEC\x48\x56\x8B\xF1\xC7\x44\x24\x48\x00\x00\x00\x00'].make_function(
    Convention.THISCALL,
    (DataType.POINTER, DataType.POINTER, DataType.POINTER),
    DataType.VOID
)

fx_firebullets = server_binary[b'\x55\x8B\xEC\x83\xE4\xF8\x81\xEC\x40\x02\x00\x00'].make_function(
    Convention.CDECL,
    (DataType.INT, DataType.POINTER, DataType.POINTER, DataType.INT, DataType.INT, DataType.INT, DataType.FLOAT),
    DataType.VOID
)

@PreHook(start_lag_compensation)
def pre_hook(stack_data):
    print('start_lag_compensation')

@PreHook(fx_firebullets)
def pre_hook(stack_data):
    print('fx_firebullets')

Both function should be called when player shoot.
