* Visual Studio Project Overhaul + Cleanup * SDL2 project for Windows * Re-added game client icon to SDL2 code * Renamed "AppPlatform_windows" to "AppPlatform_win32" (this is the name of the Windows API and is not representative of the architecture type) * Renamed "LoggerWindows" to "LoggerWin32" * Renamed "SoundSystemWindows to "SoundSystemDS" (DirectSound). This may be used for the 360, so it wouldn't really be Windows-specific then. * Moved "ClientSideNetworkHandler" from "network" to "client/network". We don't need it being compiled for the server if the client's the only thing that needs it. * I wonder if this still works on macOS... * Bugfixes & Fixed for macOS * Options::savePropertiesToFile Logging Bugfix * Silence Winsock Deprecation Warnings in RakNet * VS Project Improvements - Replaced 50 billion relative paths with $(MC_ROOT) - Added $(RAKNET_PATH) variable to override RakNet location - Re-added gitignore for .vcxproj.user files - Added debugging config to Directory.Builds.props - Slimmed down project configurations for SDL2 * VS Project Config Bugfixes - Fixed RakNet header path for additional includes * RakNet Target for XCode * XCode Project Config Fixes * Packet logging * Network VS Project Filter Fix * Fix RakNet Packet ID Length We previously didn't have consistency between old and new C++ regarding PacketType enum length. Now we do. This is required or else it completely breaks networking between the versions. * Additional RakNet Error Handling * Disable packet logging * * Fix CMakeLists.txt This reflects the relocation of ClientSideNetworkHandler.cpp. * * Also add renderer/GL/GL.cpp to the CMakeLists.txt * * Replace libpng with stb_image * * Fix buggy water behavior. * * Put the CMakeLists of the SDL project in debug mode * Visual Studio 2010 Support * * Change the SdlIoCallbacks from an array to a single member. This fixes compilation of the sdl2 target on VS. * * Fix missing _error label. * Revert "* Fix missing _error label." This reverts commit 99a057fc84049a16c864bd840fb439a008af5c74. * Revert "* Replace libpng with stb_image" * info_updateGame Tiles --------- Co-authored-by: Brent Da Mage <BrentDaMage@users.noreply.github.com> Co-authored-by: iProgramInCpp <iprogramincpp@gmail.com>
