Find your star in the galaxy

Enter coordinates:

(You can also enter the URL, or find your coordinates with the username search here.)

Go until you find a star whose coordinate starts with ""
- If the last digit is , you went too far
- Note: your star is quite far from the centre. If you've gone too far in an empty section, it can help to go up or down a screenful and backtrack
- The coordinate is at the end of a star's URL
  - On desktop, hover over a star's name to see its URL on the bottom left of the page
  - On mobile, long press a star's name to see its URL
- To go in a straight line, you can use the arrow keys on a keyboard although it's extremely slow
Go until you find a star whose coordinate starts with ""
- Note: your star is quite far from the centre
- If the last digit is , you went too far
- Coordinates should always mention either , otherwise you strayed from the column
Your star should be in view, or very close to here, if you have not zoomed in
- You may have to hover over a few dozen stars to find your name if you are one of the lucky few who are in a dense region near the centre

General overview

Sector (the default view is in the centre, so you can see the corners of Quantum, Iron, Sulfur, and Calcite):

Copper	Ammonia	Fluorine	Carbon
Bioflux	Quantum	Iron	Stone
Lithium	Sulfur	Calcite	Electrolyte
Uranium	Tungsten	Holmium	Yumako

Quadrant (example: "Yumako IV" is above "Yumako II"):

Sector III	Sector IV
Sector I	Sector II

Region (example: "Carbon IV: Alpha" is above "Carbon II: Eta"):

Eta	Theta	Iota
Delta	Epsilon	Zeta
Alpha	Beta	Gamma

Dashed numbers (example: "Delta4-5" is above "Delta4-4"):

1-7	2-7	3-7	4-7	5-7	6-7	7-7
1-6	2-6	3-6	4-6	5-6	6-6	7-6
1-5	2-5	3-5	4-5	5-5	6-5	7-5
1-4	2-4	3-4	4-4	5-4	6-4	7-4
1-3	2-3	3-3	4-3	5-3	6-3	7-3
1-2	2-2	3-2	4-2	5-2	6-2	7-2
1-1	2-1	3-1	4-1	5-1	6-1	7-1

This is star finder version 0.1b. Note that this page has no affiliation with Wube besides that I love Factorio

Debug mode

Open the galaxy and open the developer tools (e.g., using F12). Open the debugger and find the file "static/chartbundle/spacemap.js". Set a breakpoint on the first line in the function initSpacemapViewer by clicking on the line number (currently, line 48). Reload the page (F5). The breakpoint should trigger and you can now run opts.debug = true; in the console (switch to that tab or use Escape to open one). Press the play button to run the rest of the page normally.

Congratulations, you can now zoom infinitely far in or out (the galaxy looks much nicer this way, zoomed out more than you can by default!), you get a grid when you zoom in, coordinates on the top left, and other positional debug info on the top right.

To-dos

More testing
How can we "align" the view, so that the user sees all of e.g. "Sulfur IV: Iota5-7" and not most of "Sulfur IV: Iota5-6" with only a sliver of "-7" visible? Might be hard to find your star otherwise
Parse the last bit and tell users (at step 3) where to look within the region they found. Might depend on the previous point

Check how to calculate the row/col from the coordinate name so we can say what the star should look like

starTextureVariations = [`/static/chartbundle/stars/${index + 1}.png` for index in 0..5]
...
const starId = starCoordsToId(starCoords);
if (!starIdToSprite.has(starId) && starIdToIndex(starId) != null) {
  const tex = starTextureVariations[triple32inc(starId) % starTextureVariations.length]
  const scale = baseScale + ((triple32inc(starId) % scaleVariants) * scaleStep);
  ...
function starCoordsToId(coords) {
	return (coords.col << 16) | coords.row
}
[col, row] = ???
