Mine Line Placement
« on: November 27, 2012, 02:02:55 am »
Anyone else having problems with the line placement tool following the line you set?  I keep ending up with it going off at odd angles.  Close, but off enough that creating a run between the wormholes and the cmd center is off.

I've seen that happen if "packed line" is disabled.

Yea, I tried to fix some problems Kahuna had with it shortly before the official, and apparently broke it worse in other ways ;)

Don't feel bad. Dealing with angles and packing non-trivially tileable shapes (like circles) is a real headache inducer to programmers. Especially because of rounding error issues that come into play, which may be extremely marginal in most cases but can be very noticeable once lines start getting long in hard to test ways.

I'm having some trouble placing mines using line placement as well. In my current system I've got zombie units traveling between the two worm holes where I'd like to place the mines. There's so many of them that there is never a break in the flow. If I guesstimate and place mines one by one (w/o line placement) I have no problem placing them on zombie unit path. If I try to do the same using packed line placement with a count of 25 only 2 or 3 are built at odd locations along the line. My best guess is that those locations are breaks in the zombie path where no units existed when the mines were built. The random locations are different each time. In any case, this makes placing 100 mines a big headache.

Techsys and I did some experimenting a while back on this. I updated someone else's tracker issue, I could probably dig it up after 7 PM EST if you wanted.

Anyways, it's worth noting that if it runs like "\", you get significantly different results than if it runs like "/". One's broke, the other is fine (don't remember which off the top of my head). Horizontal and vertical are both fine. If you have it at the proper angle to reproduce the bug, then and only then does it matter where the starting point is, with the result of it being closer to the vertical or horizontal. It's quite noticeable if you're attempting to place mines at around a 45 degree angle.

We were able to consistently reproduce it.

As to the mine spacing, I rather inconsistently but frequently reproduced it, often within minutes in the same session. It might be related to zoom, but I couldn't figure out anything conclusive, just a hunch.

There's one more glitch:  whenever you use the Line place, if you open up the Galaxy Map and choose one of the menus at the bottom, the line placement instructions appear added onto the menus.  See pictures for explanation.

actually, nope, I did the testing with you, LaughingThesaurus. I did Borderlands 2 with TechSY730, i believe.  Bajzillions of guns, bajzillions of starships. Same thing. Honest mistake. I might even be still more confused. I'll figure it out.

The discussion on it was in one of the announcement threads, I should be able to dig it up.
