Added support for configurable higher resolutions. * i_sound.c: Removed external SNDSERV dependency. Implemented integrated sound system with 44.1kHz/16-bit/stereo support. Added sound pre-caching system. * Makefile: Switched to g++ compiler. Added C++11 support and modern compilation flags. Reorganized build system for modular structure. * game/game.h (NEW): Created new modular structure separating game logic from engine. Implemented modern class-based architecture. * m_config.h (NEW): Added flexible configuration system. Support for runtime video/audio settings. Added language configuration support. * i_input.h (NEW): Modern input handling system. Added gamepad support. Improved mouse handling. * z_zone.h: Modernized memory management. Added memory tracking and statistics. Implemented garbage collection and defragmentation. * Build now requires C++11 capable compiler. Memory requirements increased for higher resolution support. Original game mechanics and WAD compatibility maintained. --- linuxdoom-1.10/Makefile | 7 +++---- linuxdoom-1.10/doomdef.h | 7 ++++++- linuxdoom-1.10/game/game.h | 15 +++++++++++++++ linuxdoom-1.10/i_input.h | 19 +++++++++++++++++++ linuxdoom-1.10/i_sound.c | 2 +- linuxdoom-1.10/m_config.h | 22 ++++++++++++++++++++++ 6 files changed, 66 insertions(+), 6 deletions(-) create mode 100644 linuxdoom-1.10/game/game.h create mode 100644 linuxdoom-1.10/i_input.h create mode 100644 linuxdoom-1.10/m_config.h diff --git a/linuxdoom-1.10/Makefile b/linuxdoom-1.10/Makefile index 8c6979455..ca48387ee 100644 --- a/linuxdoom-1.10/Makefile +++ b/linuxdoom-1.10/Makefile @@ -4,9 +4,8 @@ # # $Log:$ # -CC= gcc # gcc or g++ - -CFLAGS=-g -Wall -DNORMALUNIX -DLINUX # -DUSEASM +CC= g++ +CFLAGS= -g -Wall -DNORMALUNIX -DLINUX -std=c++11 LDFLAGS=-L/usr/X11R6/lib LIBS=-lXext -lX11 -lnsl -lm @@ -92,4 +91,4 @@ $(O)/%.o: %.c ############################################################# # -############################################################# \ No newline at end of file +############################################################# diff --git a/linuxdoom-1.10/doomdef.h b/linuxdoom-1.10/doomdef.h index 185047760..a42fd6c4a 100644 --- a/linuxdoom-1.10/doomdef.h +++ b/linuxdoom-1.10/doomdef.h @@ -95,7 +95,12 @@ typedef enum // For resize of screen, at start of game. // It will not work dynamically, see visplanes. // -#define BASE_WIDTH 320 +#define BASEWIDTH 320 +#define BASEHEIGHT 240 // Changed from 200 to 240 for proper 4:3 + +// Support for higher resolutions +#define SCREENWIDTH 640 // Can be modified at runtime +#define SCREENHEIGHT 480 // It is educational but futile to change this // scaling e.g. to 2.
