Nro's Galaxy Editor for Stellaris

As a Type-5 Kardashev being, you are able to move the stars of a mere galaxy and manipulate their waypoints as you please with just a divine click of a button.

This is just a small project that generates visual map to edit the position of stars and connects/disconnects hyperlanes. This is also my first project that I actually finished so if there are any issues, post them here.

Note: I will be taking a break now as I have completed the main objectives. I just did this as a hobby addiction really and I'm in university so I need to focus with my studies. I just did this for fun during my summer break, by "fun", I mean taking a month, usually full-time each session, of creating textures, coding and tweaking.

Instructions and Usage

The save-file doesn't need to be a fresh start, it can be used any point in time of the game. The size of the save-file only affects how long it will take to process. Post your creations on the discussions!

Initial

Before starting your shenanigans divine intervention:

• You must use 7-zip for opening the save-files.
• You must use Notepad++ if you want to open the files
• For further instructions on save files and where to locate them: Save-game editing.
• App Directory: %APPDATA%/Nro-Galaxy-Editor/

1. Open your .sav file and drag and drop the gamestate to a folder then drag that file to the screen or open it using the file explorer. (You must put it to a folder, the application won't read the temp folder)

2. Either way, the application will freeze as it tries to read the contents. Check the logs for their status.

Camera Controls

• Movement: Keyboard arrows or W A S D
• Drag camera: Right-click
• Dash: Hold Shift to dash
• Zoom: Hold Q to zoom-out and E to zoom-in (NEW: Mouse wheel now works too)
• Reset: Press R to reset position and zoom
• Name: Hold Tab to temporarily show or hide star names
• Cancel: Press Esc to cancel editor
• Scale UI: Ctrl [+ -]

Buttons

There are three groups of button: Visibility Edit Map Hover to each icon to see their descriptions

• Star Editor: there are three ways to change their position and they are toggled by default
  • Input: Click the x or y input bar to change then press Enter.
  • Arrow: Click the white cardinal arrows.
  • Drag: Click the star first then drag them anywhere. Negative values makes the drag smoother. Range: 2 to (-3)
• Hyperlane Editor: click a star and another star to either connect or disconnect, automatically decides based on whether there is already a connection. Click on the star itself if you want to cancel.
  • Isolate: Click on any star to remove all of its hyperlane
• Nebula Editor: click a star or use the UI to add/remove them, you can also resize and move the nebula where you please. NEW
• Miscellaneous
  • Search: Can use ID or Star's name to possibly find what you look for, if an input exist, it will go to the first star found.
  • Flip: Map is inverted by default, so negative x is on the right side as to imitate Stellaris map. Toggleable
  • Resume: Resumes previous session, the original gamestate. Does not resume any previous changes, if you want to update it, just drag the saved gamestate.
  • Sandbox: Turns the map into spiral DISABLED

Saving

To save the changes you have made: Simply click Map->Save. The application will freeze while it's packing the files, the larger the save is, the longer it will take. Check the Debug for status.

• The results of the changes are located: .../packed/

• Since there are difficulties in packing the file itself, two files are created instead as a result: gamestate and galactic-object

• These two files are methods on how you can put the modified gamestate:

  • gamestate: It is relatively safe now since I used a different way of saving it.

NOTE: This is before 3.3, galactic_object={ is now galactic_object= new line {

• galactic-object: A more safer method. Copy everything inside this file using Notepad++ then open your original gamestate (make a copy) and search for galactic_object={, highlight the { only and press Ctrl+Alt+B then Ctrl+V to paste what you copied before. Save and make sure "galactic_object={" is not duplicated and starbase_mgr={ is intacted.

• After that whole debacle, follow these steps properly, make a copy of the .sav file you used, DON'T ARCHIVE, MAKE A COPY and open it using 7-zip and drag the modified gamestate there directly, the file must be overwriten to work and then bam! you're done! Congratulations, now the denizens of your galaxy are confused why their constellations have changed in just a day. Was there a large clusters of wormhole that transported everyone there? Did some shmuck invented teleportation and suddenly pressed the big red button? or is everything just a simulation? Who knows? Maybe it has always been there. What was, will be; What will be, was.

Troubleshooting

All the stars are gone! Why? Did the Prethoryn or Unbidden came?

From my experience, there's two possible reasons for that

NOTE: This is before 3.3, galactic_object={ is now galactic_object= new line {

• The galactic_object={ is duplicated in which case it becomes galactic_object=galactic_object={, delete that duplicate. This usually happens when the contents of galactic-object is not copied properly, only highlight { and press Ctrl+Alt+B and copy.
• You created/archive a new .sav file, it is not recommended as it would require following these compression configurations. You should only copy your .sav file, open it in 7zip and drag your modified gamestate there so it is overwritten.

I can't click anything on the editor

• Sometimes the entities are not deleted or replaced properly, just close the application.

If there are any other issues, please go to the Issues tab and post your problem including your modified gamestate file if you can.

Changing to another save-file

If you want to change to another save-file, simply drag your new gamestate to the screen

• If there is an error or bug, exit the application and open it again.
• If the application is set to resume the previous session, either delete .../parsed or go to the app directory .../settings and change it to Resume=0

A manual way to edit

Note: This is still doable but the files mentioned here are now formatted in JSON

If the application is too buggy for you, generate a galaxy on the application then toggle the [Resume] button or change the settings to Resume=1 then go to .../parsed and there you can edit them manually using Notepad++.

The data's template can be translated as: file : attributes

• stars : ID,x,y,star_name,star_class
• hyperlanes : ID, (to,length,bridge)

*Note: new stars can't be added as it does not have an existing file on the unpacked folder and it is not advisable to delete them for now. Hyperlanes on the other hand, can be modified but you must add it on both IDs for it to work, it must be paired.

Open the application again, assuming resume is toggled, and then save again, voilà!

• Added much need information in the editor
• Made a video tutorial
• Updated README.md

1.0.0-stable: Hiatus: Search and Isolate Star functions added

My Uni officially starts this week so I won't be touching this project unless it's bug fixes.

• Search function: Uses Engine's String:Find function
• Isolate Star function

• The output directory will now open after saving is finished.

1.0.0 beta-2: Minor fixes

Justtt a bit more dopamine.

Now I take a break.

• Added save feature
• Map is now inverted at x-plane by default as to imitate the galaxy map. toggleable
• Added a resume previous session feature, off by default
• Updated README.md

The coding is a bit of a mess, Function>>Optimize, but it works as intended.

Fear the Blorg Aeternum!

0.9.2: Drag-drop savefile, read, parse, generate visual.

• Added https://github.com/gilzoide/godot-lua-pluginscript, rewrote my lua scripts from scratch
• Parses the contents of the star section of the save game using Lua since their string functions are crucial for pattern-matching.
• It can get most from elements to sub-elements either if it's used right now or not but I'm still confused why it can't get some things sometimes, added contingencies as solution for necessary variables especially the bridge variable in the hyperlane.
• Can drag and drop gamestate file to the executable to start the visual generation, so far it's the only way to initiate it.
• Added temporary icon for the application
• No way to save the changes automatically yet, that's another headache I can't afford right now. Use this as a guide what to edit on your savefile for now.
• It's a mess of a code but no errors so far.

Merged too many savefiles in one, the parallel universes are merging!

0.9: Edit Stars by dragging and clicking and optimized all code

For a month now, I have coded all the basic features needed to edit star position and the hyperlanes from scratch. The only thing I'm lacking of is translating the Lua code I made for parsing and packing, which might be another headache. Therefore, I will take a break from this after I complete my summer classes cause this is turning into my addiction.

• Optimized all code, by optimized, I compressed lines into a "for (key) in (array)" hell.
• Added ability to edit stars by dragging and clicking arrows

0.8: Star Editor

It can now edit Star Position through input, It's already 4AM in my country and I'm still doing this thing while I still have freaking projects for the summer, I need help in addiction. I have basically finished all things I need to do for coding except for translating the Lua I coded into this language. They complete the puzzle but they don't fit yet.

• Added ability to edit stars through coordinate input
• Added better UI button texture, from scratch

0.7: Hyperlane Editor

• Added buttons to toggle visiblity for names, stars and hyperlane
• Added the ability to add and remove hyperlanes

0.6: GODOT:

After trying countless studios, I find it more comfortable to use Godot-Engine since I don't have to deal with problems that will take my focus out of the things I need to do especially with my measly coding skill.

• Created a basic star and hyperlane generator
• Created textures for the map,buttons and stars
• Moved to a different Github repository

0.1-0.5: Replit, Encoding and Decoding

##Old README## I HAVE SUMMER CLASS AND I SPENT A WHOLE WEEK PROCRASTINATING BY CODING THIS THING WHOLE WEEK

Results of mass editing: changing the coordinates work but changing the hyperlane crashes

• Cleaned the test files except for the saves, optimized parsing and packing.

• Added else if statement because the string pattern matching goes bananas and decides to switch to another pattern type.

• Can read then write and replace.

• Positions can be changed, doesn't seem to crash but hyperlanes are an issue, they cause the crash on mass edit

• Now detects bridge=yes variable from hyperlane, (what are they use for??)

• I'll stop this for now, spent a week doing this, still have summer classes so, will take a break in a month

Alpha version: Roblox Studio

My only intention was to visualize my map so I can edit them, now look what happend, I made this for a whole month and more and more!...
