[1.10b] Mac D2 Function List

[Contrail]

This is the Mac counterpart to the 1.10 D2 Functions List in the Code Editing forum. Any contributions to this list would be quite welcome. In addition to the normal information about each function, the corresponding Windows D2 function from version 1.10 should be listed if one is known to exist. The function ordinals I'm giving here were derived using PEFViewer, a tool for viewing PEF executable files I downloaded from the Apple Developer Connection website.

Diablo II (Carbon).3634 - Get gold limit in character inventory from ptUnit
Diablo II (Carbon).3866 - Gets stat value (base plus items)

That is an impressive start! I bet Souricette would have loved to have known about that last function.

One minor nit, the Windows equivalent functions pointed to are for v1.10 and v1.09x only. When Blizzard Leftover released v1.11 they scrambled the decks badly, then they did it again with v1.11b. Nefarius has been working in the latest version and uses those ordinals exclusively, while some of us dinosaurs (myself included) still work in the older versions.

I'm sure he would've, although the conversion isn't completely perfect for generating bin files for output. There's one multibyte bin datatype (0x17) that doesn't get converted from little-endian to big-endian for some reason, so I had to write some custom code to fix those particular values since they still get generated as big-endian. Thankfully it seems to only be used in a handful of files.

I actually have a longer list that's just equivalences between functions in the Mac version and the Windows version, which were reasoned out while doing some side-by-side comparisons of the same function in both versions. It would've been a lot harder to figure out these functions if I didn't have what's known about the Windows version to use as a reference.

I've edited the initial post to clarify which version of Windows D2 the equivalent functions are taken from. I think it makes the most sense to use the same version on each platform when comparing functions between platforms. If I ever make a 1.11b version of this list, I'd use Windows 1.11b ordinals for the equivalent functions.

That one is strange. Unlike the other datatypes, this type serves to call any number of functions based on the field's purpose. If you trap the call to Diablo II (Carbon).2387 for Monstats, Monstats2, MonPreset and Cubemain, you should see the linking functions used by each type 0x17 field in the stack build (assuming the Mac equivalent formats the inputs the same way).
