Lunar Ball / Lunar Pool. It is a minigolf-esque pocket billiards game.

Game objectives

  • Emulator used: FCEU version 0.98.ihavenoidea
  • Complete all 60 boards starting from 1
    • It is possible to begin from any board, including 60, but you have to complete all 60 to get the ending
  • Single player
  • Friction setting: 0 (NONE)
    • See below for notes on this
  • Fastest time
  • Uses death to save time
  • Does not utilize glitches (there exists one, but it was not invoked in this movie)

N/A game objectives

  • This game is completely deterministic. There is no "manipulates luck".
  • There are no dinosaurs in this game.

Comments

This movie was created mostly using a computer program, the development of which took several months and several iterations.
Lunar Ball has this interesting feature, that on the configuration screen, its friction setting can be arbitrarily selected from integer values 0 to 255. The default value is 32. The value 0 in particular is very interesting: It literally means "no friction whatsoever. This movie was created in the frictionless mode.
A pool game played in completely frictionless setup is a very different game from a normal pool game.
In a frictionless game, it is more than possible, that a careless shot makes the game completely unwinnable. Indeed, it is easy to demonstrate such a shot that will leave the game into an infinite loop, much resembling the effect that happens in the popular gadget, "Newton's cradle". In such a loop, there is no choice but to reset the console, terminating the game.
From a computer player's viewpoint, this means that the searching space for valid moves is drastically smaller than it is for a regular game: most shots produce either an infinite loop, or they result in the eventual demise of the cue ball. Due to the law of conservation of energy, so called "preparation shots" simply cannot be done, either. This also means that unless you "suicide" once in a while (intentionally pocket the cue ball), you get a "PERFECT" message in all boards, and that the scores skyrocket. Also, the timeout for shots should be set considerably longer than in a default-friction game, because the balls can be gliding for a long time before they eventually find a pocket.

Score and RATE


In Lunar Ball, each successful shot increases the "RATE" value of the player; each unsuccessful shot resets it. The higher the "RATE" value, the more points the player is awarded for the next successful shot. Points are awarded at a rate of 10 points per frame.
The RATE value maxes at 99, at which point completing a single 6-ball board gives 20790 points ((6+5+4+3+2+1)*99*10), plus the PERFECT bonus. Tallying that amount takes more than half a minute. Because nobody wants to watch 15 minutes of score tallying, it is a good idea to reset the RATE value every once in a while.
However, because this game mode is frictionless, the only possible method that a finite shot can be unsuccessful, is when it shoots the cue ball into a pocket. This I call "suicide", and this movie features that action every once in a while, and it is completely intentional for the aforementioned reason.

I enjoyed this quite a bit. One shot on board 38 seemed questionable to my untrained eye, though.

So wait, was the point of this speed or fewest shots? EDIT: I guess speed, however at points it seems slow. It's surprising to me, however I can kind of understand the reasoning behind this being much due to the "no-friction" thing.

I agree with Xkeeper. Pocketing the white ball just to minimize score tallies somehow goes against the awesomeness of playing perfectly. This is one of the cases where a hack would be preferable to the original to me. It was pretty cool, but long.

This game is perfectly suited for Bisqwit; a man, a myth and a genius (he is part of mensa for heavens sake). So the game choice is spot on for your taste and intelligence :) Like Truncated said, it is good but a bit too long. Despite that, I give this a yes vote. Although I recommend you to reexamine your run and find further improvements.

The last shot in board 38 was done in such a convoluted way because there was no direct angle that would have resulted in the complete halt of the cue ball, due to numerical inaccuracies in the game. Only 256 possible aiming directions after all. andrewg: The point was a bit of both, but with emphasis on speed. At each round, the shot or pair-of-shots was chosen that resulted in the greatest value for the expression "num_pocketed / (nframes+6)", where "num_pocketed" is the number of balls pocketed in the end, excluding the cue ball, and "nframes" is the number of frames before the next shot is available, including the time spent tallying scores and any waits for the board to reset. Usually the number of frames saved by a death, compared by a deathless shot (which would have otherwise accomplished the same result, but with more score), was around 200. This does not mean that the deaths accounted to only ~2000 frames of saving though. Skipping the death means exponential accumulation of score, not linear. AngerFist: Improving the run is a matter of devising new algorithms or new rules to play by. There is one drawback to the algorithm used by my bot: It always optimizes the *current* shot for the best speed as shown above. It is theoretically possible for a number of reasons, that shooting a less optimal shot *now* allows you to shoot an even more optimal shot *next*. In fact, I corrected two or three such situations in this movie manually (and a dozen of those in the upcoming standard friction run), but it is mathematically impractical to optimize them consistently, due to the exponential increase of the search space. That said, I sort of agree with Xkeeper. The score tallying delay is evil.

It looks like you sometimes just shoot the cue ball straight into a pocket without touching the other balls...why?

Out of nonparticular interest, I created a hacked ROM that makes the score tallying very quick. To those who wonder whether it is possible and better to pocket all six balls in the first board, here's the running log of this new attempt:

It shows how it found a way to pocket 6 balls, but then it found a way to pocket 5 balls that is faster per-ball than the 6-ball way.

Well, here's hoping we'll see a hacked all-perfect lowest-shots run sooner or later. Even if not meant for publishing.

There, optimized Bisqwit's screenshot (Which used a slightly odd resolution... the AVI I dumped is 256*224, Bisqwits screenshot was 256*232, I just added a transparent 8 pixel border below). Now someone set this to accepted already, pleaaaaaaaaaaaaaase.

I watched about 20 boards and enjoyed it more than the normal friction WIP, because it doesn't have those setup shots. I still disliked pocketing the cue ball, but it wasn't that bad. I guess I'll watch a couple of boards more and then decide what I vote. EDIT: I watched some more boards and I found this run entertaining. Voting yes.

I enjoyed this movie because it was a lot like watching somebody solve a bunch of puzzles. Knowing that a bot created most of the input added some entertainment as well. Certain stages (e.g. 52) had some unexpectedly clever shots that pocketed all the balls at once. This gets a yes vote from me. I only have a couple of questions: 1. On stage 43, why did you suicide twice? I couldn't see any obvious reason for it. 2. What exactly is going on when a (very) slowly-moving ball hits another and they both stop? Shouldn't one or both of them keep moving because of the frictionless setting?

Thanks for the feedback. Here are answers to your questions: 1a) Upon stage 43 begin, the RATE value was 30. Shooting the first shot as-is would have given a bonus of 30*32+20*31+10*30 points, that is 1880. The first suicide changed it to 30*3+20*2+10*1, that is 140. The difference is 1740 points, e.g. 174 frames, or 2.9 seconds. Which was a larger a saving than the delay of the suicide. 1b) At the beginning of the second shot, the RATE value was 8. Shooting the second shot as-is would have given a bonus of 60*10+50*9+40*8 points, that is 1370. The second suicide changed it to 60*3+50*2+40*1 points, that is 320. The difference is 1050 points, e.g. 105 frames, or 1.75 seconds. Which was a again apparently larger a saving than the delay of the suicide. 2) On impact, the kinetic power is divided between the two colliding balls in a manner that depends on the angle of collision. If the kinetic power is low enough, it may be that after dividing it, it is below the minimum value positive expressible with the fixed point mathematics used in the game. E.g. When you divide 0.01 (hex) by 2, you get 0.008 (hex), which gets saved as 0.00, that is interpreted as halt. The threshold for halt may actually be even higher in this game.

Question: Why did you use the Japanese version instead of the (U) version? Shouldn't you have used the U version? This run desyncs on both (E) and (U) versions. Also, the (E) version appears to be sped up a lot (due to NTSC/PAL differences). Another suggestion: at the submission text, point out how many shots it was required to complete each table (and how many balls went to a pocket, and which ones were just suicide shots), as well as the time for each table. I bet this type of info will be useful on future runs.

Thanks for the feedback, CrazyTerabyte. I used the Japanese version because I am familiar with it (due to it being the only version included on any multigame carts I have had access to). Apologies for any and all inconvenience caused by this fact. The submission message could indeed be more informative. I wrote it kind of in a hurry and without planning. Such information as the number of balls / frames / suicides per level could easily be collected by anyone; it's just some labor that I do not bother to do. Apologies.
