From db2b98c248a97d22dacca38dc5382095e288cbc5 Mon Sep 17 00:00:00 2001 From: Roman Masanin <52833910+theR4K@users.noreply.github.com> Date: Thu, 3 Aug 2023 19:09:22 +0200 Subject: [PATCH] MxDirectDraw functions and structures (#33) * MxDirectDraw functions and structures * fix indents, and globals * fix build, add mxdirectdraw build configuration * add new files to cmake * MxDirectDraw: Add code from my PR #19 on main repo Merging in the missing functions from my pull request for MxDirectDraw on the main repo. Credit to @foxtacles for the GetPrimaryBitDepth function. All match 100% on reccmp except ErrorToString, but the problem there is with the jump table at the end. Co-authored-by: Christian Semmler * improve match * improve accuracy * improve accuracy * move _countof, impove up to 96.90% * Update LEGO1/mxdirectdraw.h Co-authored-by: MattKC <34096995+itsmattkc@users.noreply.github.com> * Update LEGO1/mxdirectdraw.cpp Co-authored-by: MattKC <34096995+itsmattkc@users.noreply.github.com> * Update LEGO1/mxdirectdraw.cpp Co-authored-by: MattKC <34096995+itsmattkc@users.noreply.github.com> * Update LEGO1/mxdirectdraw.cpp Co-authored-by: MattKC <34096995+itsmattkc@users.noreply.github.com> * Update LEGO1/mxdirectdraw.cpp * Update LEGO1/mxdirectdraw.cpp --------- Co-authored-by: itsmattkc <34096995+itsmattkc@users.noreply.github.com> Co-authored-by: disinvite Co-authored-by: Christian Semmler --- .gitignore | 1 + LEGO1/decomp.h | 4 + LEGO1/mxdirect3d.cpp | 0 LEGO1/mxdirect3d.h | 0 LEGO1/mxdirectdraw.cpp | 1221 +++++++++++++++++++++++++++++++++++++++- LEGO1/mxdirectdraw.h | 118 ++++ 6 files changed, 1334 insertions(+), 10 deletions(-) create mode 100644 LEGO1/mxdirect3d.cpp create mode 100644 LEGO1/mxdirect3d.h diff --git a/.gitignore b/.gitignore index 402fb660..8768f944 100644 --- a/.gitignore +++ b/.gitignore @@ -1,6 +1,7 @@ Debug/ Release/ *.ncb +/.vs ISLE.EXE LEGO1.DLL build/ diff --git a/LEGO1/decomp.h b/LEGO1/decomp.h index 5466e6d8..cd179ae6 100644 --- a/LEGO1/decomp.h +++ b/LEGO1/decomp.h @@ -4,6 +4,10 @@ #define DECOMP_STATIC_ASSERT(V) namespace { typedef int foo[(V)?1:-1];
