You are using the wrong offset for witch attack.

This extension, also, no longer works due to WitchAttack::WitchAttack signature change after the latest patch of L4D2.

Learn signature searching so you can find the new signature yourself.

Extensions works fine on Linux, don't know about Windows.

This one requires an offset and not just a signature. I tried to learn that, but couldn't wrap my head around it.

If you need an offset then can't you get it from https://asherkin.github.io/vtable/ ?

The offset that is used in this extension is not a virtual one. I already tried dumping the tables manually and its just not there.

If you need an offset that points to a C++ class property, then you are in for some real serious pain.

Unless if you can reverse engineer the game AND know the game's internals really well, you won't be able to find it. Essentially you are looking for a C++ property like m_bDisabled or m_nTotalCurrency, which doesn't show up symbolically (variable names don't get preserved), but rather show up as something like (pointer + offset) like: *(this + 934), where 934 is the offset you are looking for.

You need to know where this C++ property is located (which functions accesses it), locate at least one of those functions in both linux and windows, and read the offset (similar to signature scanning except here neither windows nor linux has the symbol to the property of interest).

Since the extension works on linux, you can try to search for the offset in linux and cross-reference to windows. Alternatively, if you are lazy, do +/- 4 to the windows offset and keep restarting your server until the extension works (no guarantee of working but it's definitely an option). For example, test offset 1052, 1044, 1040, 1036, ...until you run out of patience.

I'm not sure, if the offset has changed for windows this time or not, but I updated the signatures. Would someone be willing to test it?

I've used for a month and found out that it would accidentally crash the Windows server with latest Sourcemod when players or bot survivors died.
