build for android

please note that android support is highly experimental!
gamepad, mouse input is currently borked, and proper touch controls are not available.
srgb and blending are broken too, which leads to many rendering issues

prerequisites: Android SDK, command line tools, NDK, platform-tools, latest JDK
(make sure that your $PATH variable is configured properly)

Setup:

cargo install cargo-apk
cargo target add aarch64-linux-android

Build:

--no-default-features is required for keyboard input!
(prefer-raw-events feature must be disabled on android)

Mouse input is not implemented, touch only!

cargo apk build -p kubi --no-default-features

Run:

cargo apk run -p kubi --no-default-features

android controls

Left side: Movement
Rigth side: Camera controls
Bottom right corner:
- B (e.g. place blocks)
- A (e.g. break, attack)

address = "0.0.0.0:12345"     # ip address to bind to
max_clients = 32              # max amount of connected clients
timeout_ms = 10000            # client timeout in ms
