mir2x

With C++20 coroutine feature support, you need a compiler supports c++20 to compile.

mir2x is a c/s based mir2ei implementation with various platforms supported. It contains all need components for game players and developers:

• client
• monoserver
• pkgviewer
• animaker
• mapeditor

Windows

For windows please download binaries from appveyor

https://ci.appveyor.com/project/etorth/mir2x/build/artifacts

If complains missing dll, you may need to copy .dll files from mir2x/bin to mir2x/client and mir2x/server.

Building from source

mir2x requires cmake v3.12 and gcc support c++20 to run. Mir2x needs some pre-installed packages before compile:

libsdl2-dev
libsdl2-image-dev
libsdl2-ttf-dev
libsdl2-mixer-dev
libpng-dev
liblua5.3-dev
libfltk1.3-dev

Cmake complains if libs are missing. After install all these dependencies, clone and compile the repo. By default cmake tries to install in /usr/local. use ``CMAKE_INSTALL_PREFIX" to customize.

$ git clone https://github.com/etorth/mir2x.git
$ cd mir2x
$ mkdir b
$ cd b
$ cmake .. -DCMAKE_INSTALL_PREFIX=install
$ make
$ make install

First time run

The above steps install binaries in mir2x/b/install, to start the monoserver, click menu server/launch to start the service before start client:

$ cd mir2x/b/install/server
$ ./monoserver

Start client, currently you can use default account (id = test, pwd = 123456) to try it:

$ cd mir2x/b/install/client
$ ./client

Currently the magic spell part is not fully done yet, you can press key to trigger:

t: Thunder
s: Summon Taoist Dog
u: Summon Taoist Skeleton
f: Taoist Fire
y: Shield

Code style

Global variables:

1. no globals of builtin types, they are lacking of multithread access control.
2. no globals of class instances, use pointer instead, for better construction/destruction control.
3. all member functions of globals should be:
   • simple
   • thread-safe
   • atomic operations
4. name all global pointers as g_XXXX and use them by extern, and
   • allocate them at beginning of main()
   • remain valid during the whole run, and ONLY free them at process exit.

Error handling:

1. use exception for good/bad path control, force catch at exit of main() or clone().
2. do strict parameters checking before doing actual logic, no assumptions.
3. let the crash happen ASAP if any fatal error detected

General rules:

1. make all member functions self-contained, avoid first/second half logic.
2. don't do optimization too early, perfer simple/clear logic.

Packages

mir2x uses a number of open source projects to work properly, and of course itself is open source with a public repository on github, please remind me if I missed anything.
