OpenStarbound for Android

PortActive

An existing game or its source code brought to another platform.

About

OpenStarbound Mobile (oSBM) is a mobile-focused port of OpenStarbound for Android and iOS devices. You must own a copy of Starbound, because base game assets are not provided. The README says the code is worked on whenever the author has spare time.

How it differs from the original

It adds mobile controls: direct screen touch gestures, gyro aiming, an aim joystick, a D-pad, gamepad remapping, and custom on-screen buttons and macros. It also builds as a Nintendo Switch homebrew NRO and for Linux ARM64.

Getting started

Then tap Launch, and touch controls appear in-game while Enable touch overlay is on.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (Android, iOS version).

You must own a copy of the game and provide its packed.pak assets.

Features

The port is focused on Android and iOS devices.
Touch options include direct screen gestures, gyro aiming, an aim joystick, and a D-pad.
Gamepad controls can be remapped.
One touch button can trigger a macro that presses multiple keyboard keys at the same time.

How to install

Find packed.pak in the assets folder of your game installation and send it to your phone.
In the launcher, select the file with “Pick packed.pak”; you only need to select it once unless you delete your data.
After selecting packed.pak, click Launch. Touch controls appear in-game when the touch overlay is enabled.

Controls

With direct screen gestures enabled, a tap anywhere acts as a left click at that location.
With direct screen gestures enabled, hold one finger where you want to aim, then tap or hold a second finger to right-click at that aimed location.
Custom button behaviors include single press, rapid fire/repeat, hold, and toggle.

Summarised from the project's README.

Additional notes

Releases: The latest stable release is recommended, as the nightly build can have bugs.
