Call AddLayeredSequence

[rovizon]

Hello! I am trying to blend animations on prop_dynamic_override entity. Trying to call CBaseAnimatingOverlay::AddLayeredSequence:

Syntax: Select all

import memory
from memory import Convention, DataType

server = memory.find_binary('server')

add_layered_sequence = server[b'\x55\x8B\xEC\x51\x53\xFF\x75\x0C'].make_function(
    Convention.THISCALL,
    [DataType.INT, DataType.INT, DataType.INT],
    DataType.INT
)

add_layered_sequence(entity.index, 0, 0)

https://github.com/ValveSoftware/source ... y.cpp#L639

And got an error:

Code: Select all

RuntimeError: Access violation while reading address '112022711'.

Please tell me what am i doing wrong?

Syntax: Select all

import memory
from memory import Convention, DataType

server = memory.find_binary('server')

add_layered_sequence = server[b'\x55\x8B\xEC\x51\x53\xFF\x75\x0C'].make_function(
    Convention.THISCALL,
    [DataType.POINTER, DataType.INT, DataType.INT],
    DataType.INT
)

add_layered_sequence(entity.pointer, 0, 0)

The first argument has to be a pointer (probably the entity?).

The same error:

Code: Select all

RuntimeError: Access violation while writing address '1775008724'.

I sometimes don't understand hooking C++ functions, but in source there's 2 int arguments, while you waiting 3. Why?

[rovizon]

Because I need to add a layer for some specific entity. Therefore, I pass the desired entity as the first argument (the this-pointer). Maybe I'm wrong and you need to do it somehow differently.

prop_dynamic_override

This entity does not inherit from CBaseAnimatingOverlay.
