Tired of using the ruler two stars at a time and manually adding up your ETAs? ME TOO!
The following is a script I started recently. I got some awesome help today from @Qwerty! It overrides ruler functions so that instead of measuring between two stars you can continue clicking stars and measure a more complicated route. I’m sure there are some problems with it, and there are still some things I’d like it to do, so I’ll provide the “unminified” code here so that others can collaborate.
Here’s a couple of screenshots:
No warpgates:
Through warpgates, the total “Warp Gate Flight Time” will be correct:
Now here’s the code. In chrome, you can paste this into the dev console and it should work:

Hopefully somebody can help minify it and make it in to a bookmarklet, I took a couple of stabs at encoding it to base64 but couldn’t get it to work. Of course, what would be REALLY swell is if @JayKyburz put this behavior in the game!
Update
Here is a bookmarklet that should work. Don’t forget to remove the leading +

Update
Switched to the MIT license.
Update
If you start the ruler from a carrier and measure to it’s immediate destination, the ruler will use the carrier’s ETA rather than calculating it. This is to account for a carrier travelling between two gates:
Previously, that ETA would have been 3 hours since it would have been calculated off of the carrier distance.
Use the stuff @JayKyburz exposed for us rather than searching for it.
Update
Per discussion with @JayKyburz:
- Ruler is always “gated” meaning it always displays both the eta and the gated eta. Now the eta should be correct and the gated eta should represent the eta if all the stars are gated. The only time that’s not true is some logic to account for the fact that you can’t build gates on carriers.
- Ruler will display the total distance of the chain instead of the last link’s distance.
- Will display the maximum hyperspace required for any link in the ruler chain.
Update
Tweaked the drawing code slightly to make the ruler more transparent (to a point) the farther you go. In other words, as you add links, the older ones will be more transparent and the most recent will be the least transparent.
Update
Fixed the global loop variable.
Update
It got put in the game! Best ruler ever!
As a C++ developer, JavaScript is weird and scary to me. This is me asking stupid questions of my old friend the actual web developer, lol:
