Keyboard Zoo

Cross platform, physics based game for children.

• Custom engine, just Rust + SDL2
• Full screen & toddler safe.
• Random dynamic backgrounds.
• Each key press (smash) generates a letter, number or object & plays a sound.
• Objects are realistically simulated in a 2D physics model.
• All graphics & sounds are easily replaceable.

Build

Requires vcpkg to build.

cargo install cargo-vcpkg
cargo vcpkg build
cargo build --release

All resources are embedded into the binary.

macOS

The linker will fail to link SDL2 haptics. You will need to add the following to ~/.cargo/config.toml:

[target.aarch64-apple-darwin]
rustflags = ["-C", "link-args=-weak_framework CoreHaptics"]

Config

Config is stored in yaml:

• Windows: $HOME\AppData\Roaming\rs.keyboard-zoo\
• macOS: $HOME/Library/Application\ Support/rs.keyboard-zoo/
• Linux: $XDG_CONFIG_HOME/rs.keyboard-zoo or $HOME/.config/rs.keyboard-zoo

Most of it you can ignore except:

• baby_smash_mode: enabled -> each key press has an action e.g. A spawns the letter 'A', disabled -> only use mapped controls
• run_toddler_sandbox: enable to prevent control keys from working. Requires Administrator on Windows/root on Linux/Accessibility controls on macOS.

Video Mode

• Window (default) - note if your screen is not at least 720p then keyboard-zoo may not even load on first attempt.

  video:
    mode: !Window
      width: 1280
      height: 720

• FullScreen - native fullscreen (recommended), note keyboard-zoo should scale to any weird resolution but was designed for 1080p & 4k.

  video:
    mode: !FullScreen
      width: 1920
      height: 1080
