Title: Game Mechanics Quiz 2 - Do you know more?
Post by: UpperKEES on December 06, 2010, 03:24:21 AM
Okay, here we go with the second edition of the Game Mechanics Quiz. This time with a slightly different format than Quiz 1 (http://knucklecracker.com/forums/index.php?topic=5081.msg27012#msg27012):

Rules:
- I'll post a total of 10 questions; these can be open or closed (multiple choice).
- I'll post two questions simultaneously each Wednesday (time permitting) for 5 consecutive weeks.
- Each participant has until Sunday evening at midnight forum time* (this is not your local time or adjusted forum time!) to post one or both answers.
- Each participant will receive 1 point for every correct answer.
- Because my 'answers' do not differ from yours in the sense that I get my data from testing as well, I will first post my own findings. When others found something else, we can have a nice discussion about it before we reach a consensus about the final answer. This discussion will be open for 2 days (until Tuesday midnight forum time). Points will be rewarded after that.
- You are allowed to edit your post / change your answer(s) as often as you like, but make sure you do this before the deadline.
- Answers posted or edited after the deadline will not be taken into account.
- Please make sure you specify which question you're answering. Answers without the number of the question will not be taken into account.
- The person with most points in the end wins (should be mid January).
- When there's a tie or a difference of only 1 point, I will keep asking questions until we have a winner with a 2 point lead. Anyone can participate with these additional questions and try to catch up.
- Of course you're allowed to create your own testmap in the map editor to figure it out empirically.

* Forum time (GMT/UTC minus 5 hours) is used to determine the deadline: midnight sharp every Sunday evening, no exceptions!

Title: Re: Game Mechanics Quiz 2 - Do you know more?
Post by: Kapoios on December 06, 2010, 02:20:53 PM
I'm a bit confused about question 1. The answers are not independent. D/E are special cases of A/B. Let's say I think the location of the base matters. Then, obviously, the distance of the base from the edge also matters since if you change the distance you also change the location, so I should choose both? So, what am I claiming if I choose D but not A? A but not D? Certainly if D and E are sufficient to determine the pattern, so also are A and B, since A and B contain more information (maybe they even contain C, though I don't know).

Basically, it's like saying: What determines x^2?
A: x
B: |x|

Obviously, x^2 depends on x, but not on its sign, i.e. only on its absolute value. But that doesn't stop A being right! x certainly determines x^2. Should I choose both?

Then again, in the question: What determines x^3, I could still answer both A and B if I interpret "determines" as "what does it depend on". x^3 certainly depends on |x|.

Can you please clarify it? :)

I get your point, so I rephrased answers A and B. It seems different, but it comes to the same thing. People can of course change their answers when they interpreted my initial text differently than intended.

By the way: your little math example really clarifies it for the average reader, hahaha! :P

Question 1:
Drones fly in different patterns and drop their bombs in different patterns. What determines these patterns?
A. The distance between their base and target
B. The angle between their base and target
C. Their take-off angle


Perhaps now I'm missing something, but is the take-off angle not determined by B. The angle between their base and target?

I do seem to recollect some "randomness" in how drones take off, but if that was truly random,it would  invalidate this question, so then there is an adjunct question on "what determines the take-off angle of a drone?"

I added one more rule to avoid redundant work for me:

Because my 'answers' do not differ from yours in the sense that I get my data from testing as well, I will first post my own findings. When other participants found something else, we can have a nice discussion about it before we reach a consensus about the final answer. Points will be rewarded after that.

This will also ensure we will get all data about the game mechanics right (because that's what this quiz is all about) and will avoid unnecessary questions for Virgil, as he is busy enough with more important things.

Also please note that forum time is GMT/UTC minus 5 hours, instead of 6, as I previously stated. Thanks to mthw2vc for the correction. :)

So far as I can tell, the correct answer for both questions is G.
Title: Re: Game Mechanics Quiz 2 - Do you know more?
Post by: UpperKEES on December 13, 2010, 12:01:30 AM
Posting for Q1 & Q2 is closed now.

My findings:

Question 1:
A. The distance between their base and target
B. The angle between their base and target
C. Their take-off angle
D. The distance between their base and the edge of the map
E. The distance between their target and the edge of the map
F. A random factor

Each of the green options influences the flight route and/or the number of bombs dropped per bombing run. This would mean the correct answer is 5 out of the 6 options: J.

Question 2:
A. The percentage of the unit's surface touched by creeper
B. The creeper depth
C. The distance between the touching creeper and the center of the unit
D. The type of unit
E. The presence of an emitter touching the unit
F. Whether this unit is connected to Odin City or not

Only the type of unit and the percentage of its surface touched by the creeper determine the survival time. This would mean the correct answer is 2 out of the 6 options: G.

How can you test Q1 E?

Well, of course you can't see how the drone flies off your screen, but you can count the number of bombs it drops. In the center of your screen it could for instance be a pattern like 3-4-3-4-1, while near a corner it often becomes a pattern like 2-2-2-2-2-2-2-1. This means the run takes much longer and the bombs will be dropped with more time between them, which could be to your advantage (because more creeper will flow back).
Title: Re: Game Mechanics Quiz 2 - Do you know more?
Post by: Kapoios on December 13, 2010, 07:04:51 PM
The answers also agree with my findings. Only reason I didn't get answer 1 correct is that apparently I can't count to five!

I went a step further in testing for question 2 and found some things that might be interesting to people:

- Civilian structures (collectors, relays, storages, speeds, reactors) and survival pods only look at their central square to determine whether they are damaged (and hence destroyed, since they don't have HP)

- Military structures (blasters, mortars, drone bases, SAMs) also worry about the 8 surrounding squares so a total of 9 squares. The exception is mines, that only care about their center. Each of the 9 squares contributes equally to damage.

- The particular image (the sprite) of the structure does not matter.

- Units lose HP EVERY frame that they have a square in creeper (as opposed to walls that lose HP every 7 frames). Every frame they lose 1 HP for every one of the squares they care about.

- Units do not heal if they have at least one square in creeper. So, they can't heal and get damaged at the same time.

- Civilian structures have 0 HP. Mines have 20 HP, SAMs 200 HP, drone bases 500 HP, blasters 2500 HP, mortars 4999 HP. Units are alive at 0 HP, but die at negative HP. One might wonder why mortars have 4999 and not 5000 HP. My conjecture is that Virgil typoed a < to <= or vice versa (so, probably they have 5000 HP but die at 0 HP instead of negative). Of course, this makes no perceptible difference and doesn't matter for any reasonable purpose.

- The order of things happening is: Military units take damage, then blasters fire, then civilian units take damage. An illustration of this is the attached map. The collector and the SAM are on identical emitters capped by identical blasters. The collector survives, because its damage is checked after the blaster fires, and hence its square is clean. The SAM, however, takes damage, because the emitter fires, then damage is checked, then blaster clears the area. So it takes 1 HP damage every time the emitter (and then the blaster) fires. The careful observer might notice that it takes more than 200 times for it to die. This is because the SAM is not constantly touching creeper, and therefore has a chance to heal sometimes.

- The Thor during its building phase behaves like a civilian structure in that it has 0 HP and only cares about its central square. However, it takes damage at the same time as military structures i.e. before blasters fire and therefore, the emitter squares in the example that are safe for a collector are not safe for the Thor.

The only thing I haven't tested thoroughly is damage of Odin City, so I don't know which squares it cares about and how many HP she has. Maybe I'll get to do that at some point.

Maybe also nice to know that units heal disconnected from the network (but on the ground). I always figured they had to be connected to Odin City.

I'll keep the answers open for discussion until Tuesday midnight (forum time) and will award the points after that. Two days should be enough I guess, so I'll make this a rule for future weeks as well. Two new questions will be posted along with the rankings.

While I of course agree with your answer to question 2, I have different thoughts about problem 1.

Quote from: UpperKEES on December 13, 2010, 12:01:30 AM
My findings:

Question 1:
A. The distance between their base and target
B. The angle between their base and target
These both seem trivial and hardly affect the 'patterns' as I think of them. Merely how long the flight lasts.
C. Their take-off angle
I disagree. A drone when first built and charged will face to the right every time. Upon returning to its base, when recharged, it will face the same direction it came in for landing. The angle they take off in is one of the most predictable things about drones, and when launched from facing a particular angle, which direction they turn as they lift off is also consistent.
D. The distance between their base and the edge of the map
Confirmed. The flying patterns at takeoff do not change whatsoever based on where the edge of the map is.
E. The distance between their target and the edge of the map
Confirmed. A drone's flying patterns do not appear to be affected by the edge of the map in any situations. However, they will never drop bombs offscreen.
F. A random factor
Confirmed. Testing with launching a pre-built drone before the opening text at a consistent place, I receive different results for when it returns to base each time, with wide variations that simply cannot be caused by user error.

In bold are my findings/thoughts, color-coded for whether or not I agree.

Well, hardly sounds like partly. ;) I do understand your point however; I could have been more clear about the term 'pattern'. I meant the exact way (route) the drones fly and bomb. I'll try to be more clear with future questions.

To all: please ask when something is not entirely clear (like Grauniad and Kapoios did), as my English has its limitations. You can also send a PM if you don't want to give away your considerations. :)

The angle they take off in is one of the most predictable things about drones, and when launched from facing a particular angle, which direction they turn as they lift off is also consistent.

I believe that apart from the random factor every option is consistent. The take-off angle does influence the fly route of the drone. When it faces its target with an angle of less than 90 degrees it will turn completely into the targets direction and when the angle is more than 90 degrees it will turn until an angle of 90 degrees has been reached and take off from there, hence influencing the flight pattern.

Posting for Q1 & Q2 is closed now.

My findings:

Question 1:
A. The distance between their base and target
B. The angle between their base and target
C. Their take-off angle
D. The distance between their base and the edge of the map
E. The distance between their target and the edge of the map
F. A random factor


A. Distance mostly affects the direction of return after several bomb runs and somewhat random turns between runs. More distance means less variability in the direction the drone faces when landing. At extremely close range (ie target right next to/on the base) the first bomb run can be cut short - as in started halfway through.

B. The first bomb run will be on a line close to that between base and target point.

C. Little variation if one is sending the same drone to the same target point; but if using a drone on different targets the direction the drone faces when landing will determine which side of a line between base and target point the drone turns. A very minor factor in the direction of the first bomb run UNLESS the target point is quite close to the base.

D, E. My tests showed drone flight patterns aren't affected by the edge of the map; but drones won't drop bombs off the edge. That can make a meaningful addition to time on target; especially in the corners.

F. On my tests I observed slight random variations in how far a drone turns at the end of a run. Two drones launched on parallel tracks ended up on quite different tracks at the end of their patterns. Also; if a drone is launched at a target directly opposite the direction it faced when landing the drone can turn either left or right.

Yes, the elevation gauge is what you want to be using. Please note that you will have to pause the game a lot to be able to read it accurately, because the creeper flows back fast after damage is done! Using the O = 2 x P (http://knucklecracker.com/forums/index.php?topic=977.0) script may help you with that. Adjust the interval to 27 milliseconds to be able to advance frame by frame (in theory, because in reality you often skip a frame due to limitations of your operating system). It's not necessary to use this script though; when you time pressing the P-key well you should get the same results.
Title: Re: Game Mechanics Quiz 2 - Do you know more?
Post by: Sqaz on December 15, 2010, 12:34:43 PM
Or to be really sure, you should make a map in which if the damage is done all creeper is removed, and then one with 0.1 creeper more, which in case you're right should fail.

What's actually the use of making that second question multiple choice, I can see from your answer you just took all possible results :P

Nah, there are even more possible results, depending on your way of thinking, but I figured 15 options would be hard enough. I also considered making Q3 multiple choice, but I like having some open questions as well to reward people that test thoroughly. :)

I tried to clarify the question. A block in CW is 10 by 10 pixels. A CW map consist out of 70 by 48 blocks, so the visible playing field is 700 by 480 pixels, while your entire CW screen is 700 by 525 pixels.

We don't believe you!

I know you are a good player, but talking in majestic plural is a bit too much, my friend(s). ;D

Besides that you were wrong, as I slept for 3 hours. ;)

Oh, but wait, I still got part of it right, shouldn't that count for something?

Yes, it counts for zero points. You missed 4 valid options, so maybe I should consider assigning 1 - 4 = -3 points. :P

I was thinking one question right=one point, two=two etc.

I calculate it as 238.53720883753125696545713238553 pixels.
Do I round up or do I round down?
If round up: N:239
If round down: M:238

The question is about the maximum number of whole pixels, so for your example that would be 238.

The max distance, does that mean from the middle of the collector, relay or whatever you take to start your bridging, or when it leaves the block of that building, or the farthest point of that block?

From center to center. Now where would the center be for a 10 by 10 block? Hmmmm.... Luckily that doesn't matter. ;)

Well that'd be 7.07106781... pixels of course ;D
You should really have demanded an answer with 6 digits behind the comma, that'd be more fun :P

I just tested it, and my answer works! (Note: High precision needed.)
13 blk horizontal, 20 blk vertical -> sqrt(132+202)=sqrt(169+400)=sqrt(569)=23.853720883753125696545713238553 blocks=238.53720883753125696545713238553 pixels, round down to 238.
Last screenshot shows added collectors to facilitate checking of distances.

Thank you for this screenshot. Very interesting and helpful.

I think, however, that your post would be a bit better timed if it was around 24 hours later :) (Note that in this quiz everyone gets points for correct answers, so you are giving up your lead posting before the deadline, and maybe also spoil the fun for some.) That said, maybe you are outsmarting us, by posting a fake screenshot, or maybe an even longer distance is possible, in which case, cute strategy! :)

Q 3 =  dont know =P , so  i guess : 6 x 1 drone bomb = 3000 ccc ( or whats called )

Q 4 = O. 240

Edit : hmm i guess im to late , my time is 23 :25 now ,
or im im thinking the the wrong way =P

Sorry for the delay, I haven't been home till now. I'll post my findings tonight.
Title: Re: Game Mechanics Quiz 2 - Do you know more?
Post by: UpperKEES on December 21, 2010, 05:34:17 AM
My findings:

Answer 3:
The detonation of the mine does max. 4 damage to 48 squares. When the square where the mine was located contained more than 4 ccc of creeper this square is damaged for max. 8 ccc and only 46 other squares get damaged. Either way the initial detonation does max. 4 x 48 = 192 ccc damage.

The 5 mortar shells do 144 damage each (as described here (http://knucklecracker.com/forums/index.php?topic=5062.msg27244#msg27244)).

This means the total maximum damage for a mine comes to 192 + 5 x 144 = 912 ccc.

Answer 4:
The maximum distance between 2 units (except for relays) is 5.9999999, so anything up to 6. When bridging with 2 weapons and Odin City you can theoretically approach the distance of 24 blocks. However the maximum distance between two collectors is 23.85 blocks (20 by 13 offset), which equals 238 whole pixels. The image below demonstrates this maximum bridge.

Next time indeed better wait with posting 'prove' until after the deadline, so everybody gets a chance to think for themselves.

My findings:
I completely agree with your findings. I'd like to add a few things I've found about mines:

1) Mines decide where they will target their 5 mortar bombs randomly within a square of dimensions 20x20. The mine is located in the lower right "middle" of this square. The bombs cannot fall on top of the mine, so there are 399 possible squares for each of the five mortar bombs. Distribution seems rather uniform to me, although I haven't tested it enough.

2) The central explosion of a mine is the only thing that can inflict damage to creeper while the game is paused (by manually destroying the mine). Of course, you will not see the creeper changing colour or disappearing until the game has been unpaused and possibly several frames later, when the creeper gets redrawn. However, you can see the damage when the game is paused, by hovering your mouse over a square near the mine and looking at the elevation gauge.

3) This point is a bit more subtle. So, first of all, I'll have to revise how the various "bullets" decide the damage they make. So bear with me. Each of them has three constants attached to it: number of squares, depth, radius. For example a blaster "bullet" has 8 squares of depth 1 and radius 8. Once a blaster has chosen the target, it will look around the target in an open disk of radius 8. It will do damage up to 1 to the target, and then will start looking at the squares of the disk in some order (roughly from near to far), until either the disk has been exhausted, or it has found a total of 8 squares with creeper (that also satisfy the requirement that they are of lower or equal elevation to the target). It will do damage up to 1 to them.

Similarly, when a mortar or drone bomb falls, it will do up to 4 damage to the target cell, then start looking at an open disk of radius 8 until it either exhausts the disk or finds 36 or 50 squares respectively and do up to 4 damage to them. That's because the squares, depth, radius values for a mortar and drone bomb are 36, 4, 8 and 50, 4, 8 respectively.

Note that the target square can be targetted twice. The bullet will do damage immediately to the target square, but then relook at it while looking at the (non-punctured) disk of radius 8. This is why a blaster does damage up to 2 to its target cell and mortars and drones up to 8 (and in that case they can only hit up to 7, 35, 49 squares respectively). Technically, it hits the target, then finds that there is still creeper in that cell and rehits it.

The radius thing is demonstrated very nicely in this thread (http://knucklecracker.com/forums/index.php?topic=5062.0), where "through-the-wall" damage only goes as far as <8 squares, even though the 36 squares of damage of mortar have not been exhausted. Note that this radius has nothing to do with the range of weapons, it's a different thing completely, happening after the target has been chosen.

The special thing about mines is that their central explosion has a radius of 15! Their constants are 48, 4, 15 (squares, depth, radius). That's, of course, only for the central explosion. Their fragments are normal mortar bombs with normal mortar constants. In other words, the central mine explosion can display "through-the-wall" effects way farther, almost double the distance, than what a mortar can do.

Short story if 3) was a bit too long to read: The damage of central explosion of mine can reach any distance less than 15 cells away from the mine, as opposed to blaster, mortar and drone bullets, that can only reach less than 8 cells away from the target.



I have used these three special properties of mine explosion in the second part of my latest (http://knucklecracker.com/forums/index.php?topic=5490.0) puzzle map. Admittedly, a somewhat obscure puzzle, but I've been looking forward to posting my findings here on the quiz, so that I can give hints there! :)

QuoteThis means the total maximum damage for a mine comes to 192 + 5 x 144 = 912 ccc.
Should'nt it look like this : 192 + ( 5 x 144 ) = 912 ccc =P ,
or else the = is 29088 ccc =)

And i thought it sendt out 6 Drone shells ,
but even if it had done so ,
i still dont know how much dmg it would give =P

Crap , i was close on the distanse thingy =D

The usual convention is that multiplication has priority to addition. So those parentheses are unnecessary :)

I have updated the overall rankings (http://knucklecracker.com/forums/index.php?topic=5421.msg29624#msg29624).

Unfortunately I haven't had the time yet to come up with two new questions, let alone testing for the answers, so I'll post them next week.
