 |
|
Hello, I have found the full class of an object and I want to call methods withing the object.
I have the full source code of the program so I know exactly what the methods name is and the parameters required but how do I actually do it?
Example:
void Game::processCloseContainer(int containerId)
{
ContainerPtr container = getContainer(containerId);
if(!container) {
return;
}
m_containers[containerId] = nullptr;
container->onClose();
}
can i inject a dll and just call the methods from there?

you want to call it from Cheat Engine?
if yes then use executeCodeEx, example:
| Code: | executeCodeEx(DECLARATION, nil, 0x746050, ContainerId) --where declaration is convention of __cdecl or __stdcall calls
--ContainerId - your container id |
Alternative:
https://github.com/cheat-engine/cheat-engine/blob/847088ee0c6dd93c5d5a0833434e8670d094a203/Cheat%20Engine/bin/celua.txt#L465
and how to know call convention?
Look at the function with disassembler, find the end of that function(must be ret)
if there's any bytes after ret then it means that it has stdcall if not - cdecl
in C++ it would look like this(calling it from injected DLL, in most cases DLL are written in C++):
| Code: | void cSlowRateManager_SetSlowRate(SlowRateType SlowType, float SlowTime) noexcept
{
DWORD address = base + 0x532020; // base is game module address
((void(__cdecl*)(SlowRateType, float))address)(SlowType, SlowTime);
} |
