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.

🗂️ Project structure

Crate structure:

| Name | Description | Status | | ---- | ----------- | ------ | | crossbundle | Command-line tool for building applications | ✅ | | crossbundle-install | Crossbundle install command to install necessary packages | ✅ | | crossbundle-tools | Toolkit used in crossbundle to build/pack/sign bundles | ✅ | | crossbundle-derive | Derive macros for projects built with crossbow | ✅ | | crossbow-ads | Plugin for advertisements | 🛠 | | android-tools-rs | Android-related tools for building and developing application | ✅ | | android-manifest-rs | AndroidManifest serializer and deserializer for Rust | ✅ | | apple-bundle-rs | AppleBundleResources serializer and deserializer for Rust | ✅ |

👁️‍🗨️ Support status

Packaging status:

| Name | Description | Status | | ---- | ----------- | ------ | | Android APK | Default build result method. | ✅ | | Android AAB | Supported via --aab flag. | ✅ | | Apple Debug IPA | Default build result method. Works only on Simulator and could be run on iPhone with Dev Certificate. | 🆗 | | Apple Release IPA | Not supported yet. Crossbundle should generate xcodeproj, but user should build and sign IPA manually. | 🛠 |

Supported game engines:

| Name | Description | Status | | ---- | ----------- | ------ | | Bevy | Default build method. Injects ndk-glue into generated tmp lib.rs file. | ✅ | | Macroquad | Supported via --quad flag. Works as cargo-quad-apk but with all crossbundle features. | ✅ |

P.S: If you don't find your engine here, open an issue! We are happy to add support for new engines.

✅ = Works and tested — 🆗 = Works but may contain bugs — 🛠 = Under development — 📝 = Planned

🌀 Installation

To install crossbundle, run:

sh 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

To see full Cargo.toml Metadata documentation, visit crossbundle README.

🎏 CLI options and flags

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

```sh crossbundle -h crossbundle build android -h crossbundle run apple -h crossbundle install -h

...

```

Result of crossbundle -h:

```text USAGE: crossbundle [OPTIONS]

OPTIONS: -c, --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 "" 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.
