Thanks a lot, you just saved me from re-debugging this thing on my own (or working around it with a dummy element), I greatly appreciate sharing this.

Yep, you are correct. My y coordinates aren’t staggered like in the example.

To me the distance is 1.

This method doesn’t seem to work if the hex the start hex is 1,1 and the end hex is 2,2. The distance should be 2, but:

deltaX = 2 – 1 = 1
deltaY = 2 – 1 = 1
deltaXY = 1 – 1 = 0

Max of the set is 1. What am I doing wrong?

Thanks for taking the time to clear to write a nice explanation, this is certainly helpful!

Thanks Scott for your time and answer :)
I finally found the bug in my code :)

“javascript:” at the beginning of the line should indicate to the browser to execute the stuff that follows, when you enter it in the address bar. If not you might be able to get around the search problem by turning off an option to search from the address bar (but it makes things inconvenient the rest of the time). With JavaScript turned on this shouldn’t be an issue when copying, as clicking the box with the one-liner version should select everything, but make sure too that you’re not missing, say, the first “j” or something when you enter the code.

Mickael:

The distance is three, I think there’s a mistake in how you laid out your hex coordinates.

Looking at the first image above, if you imagine the hex shown as 0,0 to instead be 3,2… the hex shown as 1,1 would be 4,3. Then 2,2 is 5,4, and 6,5 is one hex further in that same direction for a total distance of three. Hope that helps.

I used to use this script with great success for inviting friends to events on facebook, but now I’ve found that the browsers seem to function differently, and, instead of applying the script as a command to an existing page, the browsers are treating it as if I am typing in a web address, and they are pulling up a page saying website not found, or something to that effect. I’ve tried this on Chrome, IE, and Safari, without success (but it used to work!) Is there a way around this?

Given these two points:
a.x = 3
a.y = 2
b.x = 6
b.y = 5

The calculated distance between a and b is 3, but if I draw the 2 points on a hex map, the distance is 5. I don’t understand….

Comment on Q&A: How to Set a Form’s ID in Rails? by Gregory House

Gregory House — Wed, 22 Jun 2011 22:07:05 +0000

This helped thanks. I was stuck with html5 validation interfering with my rails validation. So I added the no validate attribute to my form.

:html => { :novalidate => ‘novalidate’ }

Comment on Chomp for JavaScript by Scott VR

Scott VR — Wed, 13 Apr 2011 00:04:37 +0000

How about this?


String.prototype.chomp = function () {

  return this.replace(/(\n|\r)+$/, '');

}

Your post prompted me to include that in my standard library. Thanks.

Oh, I think I mis-communicated what I meant: by “point-top” hexes I mean what you get if you were to take either of your sample images above and rotate them 90 degrees in either direction.

So the same exact type of hex-grid you’re using, but rotated 90 degrees. I’m trying to figure out if & how that would necessitate altering the algorithm you’ve explained here? Thanks!

If I’m not mistaken, there’s an incorrect assumption in your application of the coordinate axes to “pointy-top” hexes. When you turn the hexes you’ll also want to adjust the direction of the axes, at least to use this system.

The point of this coordinate system is to allow the x and y axes to align with the hexes so they’re each hitting a hex face “flat side on”. You’ll want to make sure the way you’re drawing your axes they don’t hit hexes “point on”.

If the axes-to-hexes alignment is right then the math shouldn’t change and 2,2 to 1,4 should indeed remain a distance of 3.

Hi, thanks so much for writing this very clear write-up. It seems like your technique should work the same for either “flat-top” or “pointy-top” hexes, but for some reason I can’t get it to calculate correctly when using pointy-top hexes.

My code looks like this:

int deltaX = x1 – x2;
int deltaY = y1 – y2;
int deltaDelta = deltaX – deltaY;
int distance = abs(deltaDelta) > abs(deltaX) && abs(deltaDelta) > abs(deltaY) ?
abs(deltaDelta) : abs(deltaX) > abs(deltaY) ? abs(deltaX) : abs(deltaY);

I think that matches your explanation, though I’m not sure if my use of abs() is 100% correct. It almost works correctly, except it appears to be treating the x and y axes identically, when it should not.

For example, when I calculate the distance from 2,2 to 4,1, I get:

deltaX=-2, deltaY=1, deltaDelta=-3, distance=3

Which is correct! However, when I calculate the distance form 2,2 to 1,4, I get:

deltaX=1, deltaY=-2, deltaDelta=3, distance=3

Which is incorrect- In a point-top hex board, that distance should actually be 2. Any idea what I’m doing wrong?

I am extremely impressed with your writing skills and also with the layout on your blog. Is this a paid theme or did you customize it yourself? Either way keep up the nice quality writing, it?s rare to see a nice blog like this one these days.. :)
