Cross-Platform Rust Toolkit for Games 🏹

🏹 What is Crossbow

A goal of the crossbow project is to provide a complete infrastructure for cross-platform game development in rust. In addition, the project simplifies the creation and packaging of crates for Android, iOS, and other platforms. We want to make most of our tools - engine agnostic, to help rust game developers integrate them into their games, engines, and crates.

🌀 Installation

To install crossbundle, run:

cargo install --git=https://github.com/dodorare/crossbow crossbundle

See installation documentation for more details on how to setup environment on your platform.

🌎 Hello World example

See Hello World example here.

📚 Full documentation

To learn how to run an example project on your own, build, test, and start using crossbow - read our full documentation here.

If you want learn more about crossbundle we recommend that you read the information below.

⚠️NOTE⚠️

For the correct work of the tool, you need to set up a development environment (ex. install some libraries and tools - such as Android SDK, Android NDK, XCode, etc). More information about how to set up the environment in the Android setup and iOS setup here.

📟 CrossBundle CLI

The crossbundle is a command-line tool that encapsulates boring stuff of Android and iOS build/packaging processes and helps mobile developers to create and maintain applications written in rust programming language.

⚙️ Config Cargo.toml Metadata

🎏 CLI options and flags

To see the complete documentation for each command/subcommand you can write -h or --help:

crossbundle -h
crossbundle build android -h
crossbundle run apple -h
crossbundle install -h
# ...

Result of crossbundle -h:

USAGE:
    crossbundle [OPTIONS] <SUBCOMMAND>

OPTIONS:
    -c, --current-dir <CURRENT_DIR>    The current directory where to run all commands
    -h, --help                         Print help information
    -q, --quiet                        No output printed to stdout
    -v, --verbose                      A level of verbosity, and can be used multiple times
    -V, --version                      Print version information

SUBCOMMANDS:
    build      Starts the process of building/packaging/signing of the rust crate
    help       Print this message or the help of the given subcommand(s)
    install    Installs bundletool and Android Studio's sdkmanager
    log        Attach logger to device with running application
    new        Creates a new Cargo package in the given directory. Project will be ready to
               build with `crossbundle`
    run        Executes `build` command and then deploy and launches the application on the
               device/emulator

❌ Troubleshooting

Shared library "<lib_name>" not found

If you ran into problem of missing shared library in the apk/aab - you can fix this by placing your .so file into target/<rust-triple>/<profile>/tools/libname.so. The builder will pick the library up and put it in the final package.
