Menu for changing mission objective, difficulty, and biome settings.

About this mod

Default key is F9, change through settings.json.

Untested for multiplayer - different biome settings will likely cause terrain mismatch. Included copy/paste function hopefully works.

Follow status messages at bottom for simple instructions on how to use each tab. Some options such as setting too many objectives, or invalid biome values will crash the game.

Mission / Objectives

  1. LOAD TEMPLATES first while in the ship
  2. Select the mission you want to change (try search bar)
  3. Change min/max values of existing objectives, add or remove others (unsupported objectives from other factions may crash game)
  4. APPLY DRAFT at the bottom
  5. Select a new mission on the Galactic Map of the type you modified (Operation Reroller or similar mod recommended)

Difficulty / Map (some map functions TBA)

  1. Select the difficulty level to modify
  2. Change values, they're saved immediately
  3. Select a new mission of the difficulty you changed

Biome / Planet

  1. Hover desired planet on the Galactic Map (or it will use the planet you're already on)
  2. Select desired biome from the list (optionally: try blending two biomes)
  3. APPLY TO PLANET button at the bottom

Biome Settings

  1. Select the base biome to edit
  2. Edit exposed fields, or copy individual values from another biome via the second list
  3. Use Biome / Planet tab to swap biome when finished changing settings

Vibecoded in C with Nuklear GUI dependency included.

If you like my work consider supporting me on Ko-fi so I can use more DeepSeek tokens I'm broke and fat and ugly thanks <3 https://ko-fi.com/cloudymostly

What's new in 0.3

Changed Biomes tab to Biome / Planet and support swapping entire hovered planet instead of only after mission selection. Also small UI changes and bug fixes.
