+ +--- + +## About + +This project is developed as part of the [Epitech](https://www.epitech.eu/) +curriculum, Advanced C++ unit (Year 3). + +The primary goal of it is to design and implement a robust game engine +featuring: +- **An ECS ([`rtecs`](lib/rtecs))**: A high-performance Entity Component System + for modular game logic. +- **High level network library ([`rtnt`](lib/rtnt))**: A cross-platform, + asynchronous network library built on [Asio](https://think-async.com/Asio/) + providing reliable UDP communication. +- **Multithreading**: Decoupled game logic, rendering, and network I/O. +- **Cross-platform support**: Can run on macOS, Linux and Windows on `arm64` and + `x86_64` CPU architectures. + +To demonstrate the engine, we have recreated the mechanics of the classic 1987 +arcade game [R-Type](https://en.wikipedia.org/wiki/R-Type), serving as a +benchmark for real-time multiplayer performance. + +## Compatibility + +This project is developed using **C++23**. +It has been strictly tested and validated on the following environments: + +| Platform | Compiler / Toolchain | CMake | Status | +|:-----------------------------------------------|:-----------------------------|:---------------|:------:| +| macOS (`arm64`) 26.2 Tahoe | AppleClang `17.0.0.17000603` | `4.1.2` | ✅ | +| Linux (`x86_64`) Xubuntu 25.10 | GNU `15.2.0` | `3.31.6` | ✅ | +| Windows (`x86_64`) 10 IoT Enterprise LTSC 2024 | MSVC `19.50.35718.0` | `4.11.1-msvc1` | ✅ | + +> [!WARNING] +> While other configurations might work, they are not officially supported. +> Ensure your environment matches the C++23 requirements. + +## Getting started + +### Prerequisites + +- [Git](https://git-scm.com) +- C++ compiler supporting C++23 ([GCC](https://gcc.gnu.org) 10+, + [Clang](https://clang.llvm.org) 10+, + [MSVC](https://en.wikipedia.org/wiki/Microsoft_Visual_C%2B%2B) 19.28+) +- [CMake](https://cmake.org) 3.20+ +- [Conan](https://conan.io/) 2.0+ + +### Installation & Build + +> [!NOTE] +> Make sure to properly [setup Conan](docs/setup_conan.md) on your machine +> before. + +1. Clone the repository along with its submodules: + ```sh + git clone --recurse-submodules https://github.com/lypitech/rtype.git + cd rtype + ``` + +2. Install dependencies: + ```sh + conan install . --output-folder=build/ --build=missing -s compiler.cppstd=23 -s build_type=Release + ``` + +3. Compile the project using CMake: + ```shell + # Generate build files + cmake -B build/ -DCMAKE_BUILD_TYPE=Release + + # Build (use --parallel for faster compilation) + cmake --build build/ --config Release --parallel + ``` + +Server and client binaries will respectively be stored in +`./build/Server/r-type_server` and `./build/Client/r-type_client`. + +On Windows, they will be stored in `./build/Server/Release/r-type_server.exe` +and `./build/Client/Release/r-type_client.exe`. + +### Using Nix + +If you are a Nix user, you can run the project directly: +```shell +nix run "github:lypitech/rtype#r-type_server" -- ... +nix run "github:lypitech/rtype#r-type_client" --impure -- ... ``` -If you want the build to be faster (to use all of your CPU cores), simply add `--parallel` to the options! +> [!NOTE] +> Please note the `--impure` flag as it is necessary in order to run in a +> non-NixOS graphical environement. -### Other Targets +### Usage -You can use the following custom build targets: +This project follows a Client-Server architecture. +You MUST start the Server before any Clients. -| Target | Description | -| ------- | -------------------------------------------------------------- | -| `re` | Rebuilds the project from scratch. | -| `debug` | Builds the project with debugging symbols and logging enabled. | +1.

The protocol provides connection-oriented + features over connectionless UDP, including session management, optional + reliability and strict ordering. + +Status of This Memo + + This document does not specify an Internet standard of any kind. + Distribution of this memo is unlimited. + +1. Introduction + + rtntp is designed to provide a lightweight abstraction over User Datagram + Protocol (UDP) [RFC768], offering configurable reliability and ordering + guarantees per packet. It employs a header-based framing mechanism to manage + sequence numbers, acknowledgments, and channel separation. + + The protocol is designed to be resistant to packet loss, duplication, and + reordering, making it suitable for unstable network conditions. + +1.1. Terminology + + Peer: An endpoint participating in the connection (Client or Server) + + Session: A logical connection state established between two Peers + + Sequence ID: An increasing identifier for every packet sent + + Order ID: An increasing identifier for packets within a specific ordered + channel + + ACK: Acknowledgment of a received packet + +2. Packet Structure + + All rtntp packets share a common fixed-size header followed by a + variable-length payload. Multi-byte integer are transmitted in Network Byte + Order (Big Endian). + +2.1. Header Format + + The header is exactly 26 bytes long and is packed (1-byte alignment, no + padding). + + The fields are arranged sequentially as follows: + + Protocol ID (2 bytes, u16): + Magic number fixed at 0x2204. Used to identify valid rtntp traffic and + reject random noise. + + Protocol Version (2 bytes, u16): + Version identifier, currently 0x0002. + + Sequence ID (4 bytes, u32): + Unique, incrementing ID for this packet. Used for loss detection and + acknowledgments. + + Channel ID (1 byte, u8): + The virtual channel (0-255) this packet belongs to. Channel 0 is reserved + for internal system messages. + + Order ID (4 bytes, u32): + Incrementing ID for ordered packets on a specific channel. Set to 0 if + the packet is unordered. + + Acknowledge ID (4 bytes, u32): + The highest valid Sequence ID received from the remote peer. + + Acknowledge Bitfield (4 bytes, u32): + A bitmask representing the reception status of the 32 packets immediately + preceding the Acknowledge ID. + + Message ID (2 bytes, u16): + Identifies the type of payload (Command). IDs 0-127 are reserved for + internal use. + + Flags (1 byte, u8): + Bitmask defining packet behavior (Reliability, Ordering). + + Payload Size (2 bytes, u16): + Length of the user data following the header (in bytes). + +2.2. Flags + + The Flags field is a bitmask (encoded on 1 byte, u8) defined as follows: + + Bit 0 (0x01) - kUnreliable: + Fire and forget delivery. + + Bit 1 (0x02) - kReliable: + Guaranteed delivery. The sender will retransmit this packet until + acknowledged. + + Bit 2 (0x04) - kOrdered: + Guaranteed order. The receiver will buffer out-of-order packets to ensure + they are processed in sequence. + + Bit 3 (0x08) - kHasAck: + Indicates that the Acknowledge ID and Bitfield contain valid data. + +3. System Messages + + Packet IDs (encoded on 2 bytes, u16) 0-127 are reserved for internal rtnt + packets. + + ID Name Desc + ------------------------------------------------------------------- + 0x00 ACK Header-only acknowledgment + 0x01 RICH_ACK Contains out-of-band ACKs (old packets history) + 0x02 CONNECT Client -> Server handshake initiation + 0x03 CONNECT_ACK Server -> Client handshake completion + 0x04 DISCONNECT Session termination + If received by the Client, the Client considers + itself as kicked by the server, and closes the + connection. + If received by the Server, the Server closes the + connection. + +4. Protocol Operation + +4.1. Handshake + + 1. The Client sends a CONNECT (0x02) packet to the Server. + 2. The Server receives the packet, creates a Session, and replies + with a CONNECT_ACK (0x03) containing the assigned Session ID. + 3. When client receives CONNECT_ACK, it marks the connection as + established. + +4.2. Reliability and Acknowledgment + + rtntp uses a hybrid acknowledgment mechanism combining piggybacked + bitfields for high-efficiency scenarios and explicit Rich ACKs for high + packet-loss conditions. + +4.2.1. Standard Acknowledgement + + Every packet header carries acknowledgment information: + - Acknowledge ID: The highest Sequence ID received from the remote peer. + - Bitfield: A 32-bit mask representing the reception status of the 32 packets + immediately preceding the Acknowledge ID. + + To ensure timely acknowledgments and prevent "window sliding" race + conditions, an implementation MUST enforce an acknowledgment threshold. + If a peer receives 16 (half the bitfield size) unacknowledged packets + without having sent any packets, it MUST immediately generate and transmit an + explicit ACK (System Message 0x00). + It is possible to increase the threshold to 24, but it is strongly + disrecommended to go higher, for stability reasons. + + This safety buffer prevents the 33rd received packet from pushing the 1st + unacknowledged packet out of the bitfield window before an ACK can be + generated. + +4.2.2. Retransmission + + Packets marked with the kReliable (0x02) or kOrdered (0x04) flag are buffered + by the sender. If a reliable packet is not acknowledged within RESEND_TIMEOUT + (default: 200ms), it is retransmitted. This process repeats up to + MAX_RESEND_ATTEMPTS times (default: 8) before the connection is considered + dead. + +4.2.3. Extended Recovery + + In high packet-loss scenarios, the standard 32-bit window may be insufficient + to represent all missing packets. To handle this, rtntp implements a + reactive acknowledgment strategy: + + 1. Duplicate Detection: If a receiver processes a packet that has already + been acknowledged, it indicates that the sender is unaware of the + acknowledgment (likely due to ACK loss). + 2. Rich ACK Generation: When detecting such a duplicate or an "out-of-band" + packet, the receiver MUST queue the packet's ID for explicit + acknowledgment. + 3. Transmission: These IDs are aggregated into a `RICH_ACK` (0x01) system + packet. This packet contains a list of specific Sequence IDs that are + outside the standard bitfield window but have been successfully received. + + Note: Implementations SHOULD fragment RICH_ACK payloads to respect the + network MTU, as a single RICH_ACK may contain hundreds of IDs in extreme loss + scenarios. + +4.3. Ordering + + Sequence IDs are global per session, but Order IDs are local per Channel. + This prevents a dropped packet on Channel 1 from blocking traffic on Channel + 2. + + - If a received packet's Order ID > Next Expected, it is buffered. + - If Order ID == Next Expected, it is processed, and the expected + counter is incremented. Buffer is then processed in order (if there is + another gap, then wait again). + +5. Serialization + + Payloads are serialized sequentially without padding. + + - Primitive types are converted to Network Byte Order. + - Strings (std::string) are prefixed with a 2-byte length. + - Vectors (std::vector) and Deques (std::deque) are prefixed with a 2-byte + element count. + +6. Security considerations + + - Magic Number: Packets not starting with 0x2204 are dropped. + - Protocol Version: Protocol version contained in packet is checked and + rejected if incompatible with local version. + - Payload size: Packet is dropped if contained packet size doesn't match + actual payload size. + - Checksum (not implemented yet): Packets are dropped if checksum doesn't + match locally computed checksum. + - Future Work: Version 2.0.0 is scheduled to introduce a dedicated + security layer including packet encryption and certificate-based + authentication. + +7. Limits + + - Max Packet Size: 65,535 bytes (limited by u16 size field). + - Max String, Vector, Deque size: 65,535 bytes. + - Max Channel Count: 256 (255 for user-defined channels). + - Max User-defined Packets: 65,407 (first 128 are reserved for internal rtnt + packets) + +8.
