Talk:Glacier

0.1

I know 4th place is no surprise after your GlacialHawk releases, but debuting at 4th place above Aleph is still a very nice job. Congrats. =) --Voidious 14:13, 26 September 2009 (UTC)

Thanks. Honestly, 4th place was a surprise for me despite the strong gun proven in the GlacialHawk releases. I'd only given Glacier's movement one test before release: Glacier 0.1, GlacialHawk 1.10, and 8 HawkOnFires. In that test Glacier outscored GlacialHawk barely, but that was somewhat unsurprising: Glacier's movement is a min-risk movement that is extremely focused on HOT dodging and will assume everyone fires HOT. In the case of a bunch of HawkOnFires, that assumption holds true, but I had serious doubts about how it would operate in the wider melee field. I expected it to fall at least behind Aleph in the ranks, but it seems that it turned out to rank a little better than GlacialHawk. --Rednaxela 14:25, 26 September 2009 (UTC)

Congrats for me also! Being able to dodge HOT is very important, using that you immediatly dodge some circular targeting when your perpendicular velocity=0 as well. :)--Positive 20:53, 26 September 2009 (UTC)

Wow, this looks like a really serious contender! I don't envy you trying to fine-tune your movement, given how strong GlacialHawk already is. --Darkcanuck 22:24, 26 September 2009 (UTC)

Thanks Positive and Darkcanuck... looks like my movement has a long road ahead... particularly with the way that Portia's score jumped when it gained wavesurfing ability there. By the way Positive, I consider it quite impressive how quickly you got some wavesurfing working there :) --Rednaxela 05:01, 27 September 2009 (UTC)

Wavesurfing at the end of the melee match

Here's a little question I have about wavesurfing at the end of the melee match for Voidious/Positive/ABC: When using wavesurfing in the 1v1 stage of a melee battle, do you only start learning any wavesurfing data after it becomes 1v1, or is there soem data you carry over from the melee stage? If not, any plans to maybe do so? --Rednaxela 05:05, 27 September 2009 (UTC)

I don't carry anything over from melee. I'd be very hesitant to learn surf data from the melee portion, since you never really know if an enemy was aiming at you when they hit you, but I have considered trying it. You can probably learn if they use HOT or not pretty consistently, but I default to HOT dangers anyway. --Voidious 05:10, 27 September 2009 (UTC)

I'm not using any melee data either, for exactly the same reason as Voidious. Portia does try to collect data during melee, but only for bullets that only fall in Portia's escape angle and not in anyone elses. Those are only about 3-12 hits for a 35-round match. --Positive 15:18, 27 September 2009 (UTC)

Angled Distance

What is angled distance? I try to follow your trig, but fail. Thank you in advance. --Nat Pavasant 13:51, 28 September 2009 (UTC)

Well, it's the way that Glacier characterizes the distances/directions to the bots surrounding eachother. How/why it works however, is not something I can really explain without a diagram. I'll draw one up to explain tonight. --Rednaxela 17:39, 28 September 2009 (UTC)

I'm waiting... --Nat Pavasant 05:43, 30 September 2009 (UTC)

I've been very busy with course work and class lately, I'll have the diagram to explain it in the next few days anyway --Rednaxela 05:48, 30 September 2009 (UTC)

Take your time, don't worry. I have plenty of time now for that I just finished my final. Nat Pavasant 06:10, 30 September 2009 (UTC)

It's like this

The green square is the bot being measured. The arrow is the direction it's moving. The blue squares are surrounding bots. The thin black lines are the lines between the bots, and the thick black lines go on perpendicular to them. The orange lines are the "angled distance" measures from fixed angles relative to the measured bot's heading. Note, they can be infinite when there is no other bot on the measured side. For a segment, I used 1/angledDistance, with a special case of 0 when angledDistance is infinity, since 1/inf=nan. Hope that explains it Nat. I find it gives a good and easily segmentable measure of what opportunities of movement are open to a melee bot. --Rednaxela 00:21, 11 October 2009 (UTC)

The angle from robot's heading to the orange line is fixed, right? --Nat Pavasant 02:01, 11 October 2009 (UTC)

Yep, that's what "fixed angles relative to the measured bot's heading" means. --Rednaxela 03:52, 11 October 2009 (UTC)

Thank you. Got it. --Nat Pavasant 04:04, 11 October 2009 (UTC)

Melee Segmentation

Reading old wiki page randomly, and ran across this page oldwiki:FloodHT/Hype. Kawigi said that he manage to create working antigravity segment. Have you read that page before? --Nat Pavasant 04:04, 11 October 2009 (UTC)
