A minecraft server implementation written in C for machines with limited resources. The current server supports 1.21.9 for the client.
NOTE: This is a weekend project so i do not recommend using this for production as this is guranteed to have bugs and the general source code quality lacks in consistency.
The server was built and tested on a linux machine. To build on a Windows machine, MSVC is required.
$ sudo apt install git build-essential cmake make
$ git clone https://github.com/vimpop/UCraft/
$ cd ~/UCraft && mkdir build && cd build
$ cmake ..
$ make
In the build/src folder an executable by the name of UCraft will be produced that can be ran.
$ ./src/UCraft
[INFO]: Listening on *:25565
[INFO]: UCraft server started!
Comparing this server to the vanilla server is unfair because it lacks most, if not all, features of the vanilla server. It only has the basic primitives for a simple minigame like TNT run which is included in the code. But if you really want them in a amd64 environment:
- The server binary size is approximately 46K bytes without authentication and 90K bytes with the authentication library. Memory usage varies based on the number of active players. In the worst-case scenario with 10 players, heap usage will be around 70K bytes with authentication and 20K bytes without authentication.
- The maximum clients this server can handle is
FD_SETSIZEwhich is 1024 clients in most machines but has not been tested.
