DarkOSM is a minimalistic implementation of an object script module,
providing the interfaces necessary to write scripts for all released Dark Engine
games (Thief 1/Gold, Thief 2, and System Shock 2). Using all script services is
supported. The ANSI C implementation can be found in csrc and the ISO C++98
implementation can be found in cppsrc. Both implementations are independent of
each other and employ a common API.
libOSM consists of only the api.h header in combination with the service
headers. The API provides all interfaces and supplemental types necessary for a
script module to work with the target game. The service headers provide the
interfaces necessary to use a particular game's script services and are the
primary means of interaction.
IScript is the script interface. It is used by scripts for handling messages.
IScriptManager is the script manager interface. It is used for managing script
state, initializing services, working with messages, and several more common
tasks.
IScriptModule is the script module interface. It is used by the script module
for initializing individual scripts.
Makefiles for MinGW-w64 (GNU Make) and Visual C++ 9 (NMAKE) are provided for both the C and C++ implementations. Using the requisite make utility from the source directory will generate complete binaries. No additional dependencies are required.
A complete script module implementation is located in csrc/module.c and
cppsrc/module.cpp. For an example script, see csrc/script.c and
cppsrc/script.cpp, respectively. The included script, TestScript, simply
responds to a FrobWorldEnd message by printing to mono. More complex scripts
can be constructed by handling additional messages and using additional service
routines.
