v0.6.0

Ostraplan is an out of game ship planner for Ostranauts. Drag every buildable part, including your loaded mods, onto the game's exact tile grid, validated live against the game's own rules, so you know a design works before you lay a tile in game.

If it builds in Ostraplan, it builds in Ostranauts.

Download

Grab Ostraplan-v0.6.0.exe below and double click it. It is self contained, so no .NET install is needed.

Requires Windows, and a local Ostranauts install (Ostraplan reads the game's data and sprites at runtime, and ships no game assets).

What's inside

• Design on the real grid. Every buildable part across the game's eight tabs, game accurate autotiling, drag paint, box and hollow fill, symmetry, flood select, the Replace With tool, a ship wide reskin, group rotate, copy and paste, and unbounded undo and redo.
• Live validation (the Law). You cannot place what the game would refuse, and the ghost glows green and red with the offending tiles and the reason.
• Rooms, airtightness and Ship Rating. Flood fill compartments, room certification, and the six slot rating, ported from the game and parity tested against its own data.
• Bill of materials. Install kit counts for the whole ship or a selection.
• Import and export. Start from a core or modded template, or your own ship from a save, and export any design as a spawnable local mod.
• Edit your live ship. Import it with its identity, redesign out of game, and write it back into a copy of the save (crew, cargo, position and identity preserved, the original untouched).
• Containers and cargo. View any container's contents on the grid, and add, remove and rearrange loose cargo.
• Extras. PNG snapshots, a light and dark theme, an update check, an in app Report a Bug, and an on disk activity log for troubleshooting.

Mod aware

Resolves your loading_order.json exactly like the game, so modded parts show up in the palette. A design records the mods it needs, and opens read only if any are missing, so nothing is silently lost. Pairs with Ostrasort for registering and load ordering your mods.

Known limitations

There will absolutely be bugs and I need help from the community to squash them all. Please use the report bug button in-app to file an issue here on github. This is the best place for me to keep track and manage them all.

Ostraplan cannot draw Ship Zones yet. Any ship you import or export will lose or move its zones, so you will need to delete and redraw them. Ostraplan is under active development, and more updates over the coming weeks will address this.

Good to know

Fan made, and not affiliated with Blue Bottle Games, so please buy the game. Ostraplan ships no game assets. Save editing writes to a copy by default, but back your saves up anyway. If you find a bug, use Report a Bug in the Help menu.
