Hello! I am trying to make FireBullets function in CSS. It seems working, but gives error:

RuntimeError: Access violation while reading address '8'.

And it doesn't deal damage.

How to fix it?

import memory
from memory import Convention
from memory import DataType
from memory.hooks import PreHook
from weapons.constants import WeaponID
from commands.typed import TypedClientCommand
from players.entity import Player

server = memory.find_binary('server')

fire_bullets = server[b'\x55\x8B\xEC\x81\xEC\x20\x02\x00\x00\x53\x56'].make_function(
    Convention.THISCALL,
    [DataType.POINTER, DataType.INT, DataType.POINTER, DataType.POINTER, DataType.INT, DataType.INT, DataType.INT, DataType.FLOAT, DataType.FLOAT, DataType.FLOAT],
    DataType.VOID)

@TypedClientCommand('fb')
def fb(cmd_info):
    player = Player(cmd_info.index)
    fire_bullets(player.pointer, player.index, player.eye_location, player.view_angle, WeaponID.GLOCK, 0, 100, 0.01, 0.06, 10.0)

The calling convention is not correct. It should be CDECL. Moreover, FX_FireBullets is just for creating the effect, but not for any damage. This has to be done manually e. g. by calling Player.take_damage.
