Diagonal/true line designations
« on: February 07, 2008, 10:05:00 am »

With the advent of diagonal movement, diagonal designations are more useful.  Unfortunately, the designation tool still works in squares, making diagonal designations time consuming.  I propose a line-designation tool for this purpose.  Perhaps you could go a little farther, and turn the designation tool into true multi-point area selection.  For instance, you could dig out a triangle or rhombus easily if you could put down more than two vertices before filling in the area.

I saw this in another thread and someone swore that diagonal movement was already 1.4 times as long.

For many situations, it would be sufficient (and very useful) to be able to designate a single square and say "dig your way here".

It should take 1.4142 times as much to move.  At one point I calculated how much...

A.  Movement is "Lost" when you can't move diagonally directly in a grid based game, so you have to up-right-up-right or something.
B.  Movement is "Gained" when you do move diagonally
C.  Movement is "Lost" when you try to move at a certain angle in a hex-based game, where there isn't a flat edge.

During this process I ended up memorizing the square root of 2, which is 1.4142, the distance between two corners of a square, if the square is 1 unit long.

Ain't notin' wrong with the L_infinity norm.

At some point I worked out that dwarf diagonals are the same as rows and columns, but I forget what my methodology was.  Something about chasing a kobold I think. It convinced me at the time.

There's a beautiful* field of computer science (and mathematics) called metric embeddings that studies just this kind of thing.  In a more obtuse setting, of course.  Questions like: if you really have metric A (like the euclidean plane), but you want to approximate it using metric B (like the grid), how much are you forced to distort distances?


* beautiful means it's both complicated and useless -- like number theory or quantum mechanics.

As with so many thing, macros are your friend if you want to do diagonal designations.  See this wiki section (requires AutoHotKey; see top of that wiki page).

My own study indicated that diagonal movement really does take longer.  The bit I don't understand is that, instead of the diagonal movement itself taking longer, the move immediately *after* it takes longer.  Not sure how that works...

Google says the speed of light = 6.52679909 × 1010 leagues per fortnight

Google is amazing, but I still haven't worked out how many camel days are in a lightyear.

You are still moving on a grid, so whether you instantly move to the final square or whether it moves you there at some point during the delay period isn't all that important.  Right now, the unit moves, then it has to wait for the delay from that move to pass.  I could make it happen before or halfway through, but I'm not sweating it.  Anyway, yeah, diagonal moves take longer, by approximately 362/256.  The actual step times are only 10 or so, which doesn't multiply up very well, so there are some random elements to get it back to around 362/256, ostensibly, on average.

Well mostly it's useful for exploratory digging.  You reveal more tiles when digging diagonally than you would digging in an orthogonal direction.  Since it can be very time-consuming to find rarer metals, I use diagonals a lot.

*Tests*
Huh, you're right.  I'd have though it'd be the same, but it isn't.
Ah, I know why.  Interesting.
