1。应该是对的 NOMOD除了超高速SLIDER不给红果之外CTB理论上都可以接到 TRUE
2。这个并不是很清楚，不过HR是有上限（OA10）的OA9的歌DT的话应该还是比HR上限快吧。 NOT SURE,SHOULD BE DT.
3。可以看到影子 歌越快影子越少 OA9基本啥都看不到不过要是比较低的话可以明显看到（仔细看的话ORZ） TRUE
4。DT不给红果 但是盘子速度和水果速度都X1.5 就是不可能接到的了 FALSE
5。必须可以啊， LR已经在2月演示过FC中间那一段了。 TRUE,LIRSROSSO ACTUALLY CATCH THOSE SLIDERS ON FEB。

1.Any combination without sliders can be catched theoretically in no mod. (True or False)

: True , maybe

2.The dropping speed of the fruits is always like HR>DT>No Mod. (True or False)

: I played DT , HR many times but i never seen HR is slower than DT

3.When playing a song with HD+FL, you can still see the shadow of the fruits after you get the combo over 200. (True or False)

: I dunno but it' will be true

5.Noisia - Groundhog (Beat Juggle) DJ Larto难度理论是可以FC的(True or False)
ture。。这是光叔以实际行动告诉我的。。
joynama, misa, and a lot of pros prove that already.

1.Any combination without sliders can be catched theoretically in no mod. (True or False) True False. If you put two notes at the exact same time and they're far away from each other, it's not possible to catch both of them.

2.The dropping speed of the fruits is always like HR>DT>No Mod. (True or False) False

3.When playing a song with HD+FL, you can still see the shadow of the fruits after you get the combo over 200. (True or False) True

4.Here's the situation: There's a fruit with hyper dash in a song with no mod, but when processing with DT the hyper dash disappears. The jump, which its hyper dash has been removed in DT, also theoretically can be catched. (True or False) False. The catcher goes faster with relation to the notes on DT, and when placing the red notes it takes that into account, but the calculation it does to place the red notes screws up anyway making some jumps impossible.

5.DJ Larto diff of Noisia - Groundhog (Beat Juggle) is theoretically FCable. True

我了个去，一题不会压力很大(ˉ▽ˉb)

猜一下：

1.TRUE

2.猜都不会猜(ˉ▽ˉb)

3.TRUE 印象中是这样的

4.TRUE

大前提：如果没有红果，NO MOD能接到的JUMP，在DT中都能接到 （感觉是这样的？是这样的么？我也不确定）
小前提：
　　小前提为猜测，
　　那些在DT中去掉了红果的JMUP，在NO MOD中如果没有红果，也是能接到的。
　　　　　　（事实上，许多能够被接到的JUMP被加上了红果）
　　证明为错：事实是Double Time中去掉了红果的JUMP，在NO MOD中如果没有红果，相当一部分是接不到的
　　正如同
　　不少在NO MOD中没有红果的JUMP，在HALF TIME中会被加上红果。
结论：若某个JUMP 在 NO MOD中为HYPER DSAH，而在DT中非HYPER DASH，该JUMP在DT中可完成

5.果然没摸过那个难度(ˉ▽ˉb)，既然都说行就行了呗

Thx for all the answers~
But i see only one person make it all correct. I'll show my answer tomorrow, we can discuss if u think i'm wrong xD

1. Yes, i think ALL is theorecally possible (TRUE)
2. Yes, althought some players can do HR before DT (TRUE)
3. Yes, but you have to see the screen carefully (and not always you can see the shadow but is possible) (TRUE)
4. Yes, i have 3 or 4 maps i did hyperjumps mo mod, no hyperjumps DT mod xDD (Theoretically, with DT you have the enought speed to catch it, but not always, only in some special hyperjumps) (TRUE sometimes.. xD)
5. mmmmmm, true, that sliders are madness but you did xD (TRUE)

All are my opinion, can be false, i wait others opinion.

To all: for question 1,
this screenshot can show something.. i think..
because this is the problem i faced in maping this song..So i think it is the turth..lol~
to mikhe: do you remember this song? i think the problem for you cannot get a good result is just this WTF thing..

人非auto,假设真的有那种反应力及手速的话我想应该还是能接住的,只是没有而已...

2.×
HR不可超越OA10,而DT可以

3.√
SF姥爷说是就是了X_X

4.√
理论上红果出现的条件判定应该为"在当前下落速度&盘子移动速度&水果大小的条件下不可能以任何方式接住这个组合"
这样的话才会出现了DT变成none出现了红果,none变成HT出现了红果.
既然是理论,就要考虑的是auto级的反应力了...

5.√
没玩过,大家说对就对吧/.

看来这次的题目有不少争议。以下是我给出的这些题目的答案，如果你认为我的答案有误，我们可以进行进一步的讨论。
1．错。我想答案其实已经在steven的图中得到体现了，如果你觉得这种情况很不可思议的话你可以看下以下的解释。
A◎B______________C◎D______________E◎F
A◎B______________C◎D______________E◎F
A◎B______________C◎D______________E◎F

首先我们要重新明确极限跳的定义。所谓极限跳就是你需要用盘子的一侧边缘去接第一个果子然后你才能够用另一侧边缘接到第二个果子。明确了这个之后我们可以看上面的简易图，图中有2个极限跳，你必须在位置B用左边缘去接住第一个果子，然后全程按住加速，你才能正好在C处用右边缘接住第二个果子。而问题就在于要接住第三个果子你必须在接住第二个的时候位于D点，这显然和接住前2个的情形矛盾了。这种情况也就是steven的图中的，这3个没有红过，但3个之中你最多接住2个。所以答案是错。

2．错。misa大爷已经说得很清楚了，OA10中DT>HR=No mod。
3．对。我想pieguy的回答应该是具有最高的权威性了吧 :3
4．错。其实mikhe是对，可惜他的答案错了。的确有时是能接住的，但是DT打得多的应该都知道有些去红果的很扯蛋，根本不可能接住，所以答案也是错。
5．对。这个么，大家期待未来的某年某月某日我的replay吧

Seems there’s some controversy with some question. And here’s my opinion of the questions, if u think I’m wrong, please let me know and we can further discuss about it.

1.False. I think the answer was proved by steven’s snap(thx steven). And if u think the scenario is weird and cannot understand it, please see my explanation below.
A◎B______________C◎D______________E◎F
A◎B______________C◎D______________E◎F
A◎B______________C◎D______________E◎F
First we go review the defination of the limit jump. The limit jump means you should use one side edge to catch the first fruit and another side edge to catch the second. Then lets go to the scenario above. There are two limit jumps in the scenario, to catch the first two, u should be at B point and use the left edge to catch the first, and then hold the dash all the time, and u are just be able to reach C and catch the second one. But you should be at D when u catch the second one as the prerequisites to catch third one, so the third one must be missed if u catch the first two. This is the scenario in steven’s illustration and this made the answer to be false.

2.False. As misa said. Songs with OA10 is DT>HR=No mod. U can just try it by editing one song to OA10 and then u will find the result.
3.True. I think pieguy’s answer is with the highest authority. :3
4.False. U r right mikhe :3, but ur answer goes the wrong way. Yes, its no doubt that u can catch such jump sometimes, but some of the jumps meet the situation even cannot be catched theoretically. I think if u r a DT-preferring player, u will find some of the jumps without hyper dash really impossible to catch.
5.True. As one of my favourate song, I’m glad to see no one is wrong about this. xD

题目是不是太简单了？！
btw, problems too easy?!

第一题第二个就是红果了吧

按理说自从更新出了红果之后理论上不存在接不到的果子

其实我一直认为，系统认为一个JUMPING是否是红果，其实并没有考虑盘子的问题(ˉ▽ˉb)。个人感觉，两个果子间，若不可能都用盘子正中接到，就会变成HYPER DASH。
收回这句，考虑错了，肯定不是正中判定的

不过判定HYPER DASH的距离也有可能加上了半个盘子的长度。因为如果这个额外的距离小于等于半个盘子长度时，前面曾提到的那种情形就不会出现。

另外我认为
A◎B______________C◎D______________E◎F
A◎B______________C◎D______________E◎F
A◎B______________C◎D______________E◎F
这种情形，是相当容易考虑到的，若PP加入红果时，没有考虑到这种情况就太2了(ˉ▽ˉb)。毕竟红果的本来目的，就是希望所有JUMPING都能够被完成。
修正：我现在无理由的觉得，如果仅有3个果子，12极限非红果，23极限非红果，123的组合是可接到的，但3个以上的情形就是无法接到的。

反正绝对的，判定的距离不是用的果子间距+一个盘子的长度，即不会是 当 用盘子的一侧边缘去接第一个果子后 无法 用另一侧边缘接到第二个果子， 这个JUMP才会变成 HYPER DASH....毕竟没有HYPER DASH时代的很多可行JUMP都被加上了红果...
这一点还是肯定的。鬼知道PP到底怎么算红果的(ˉ▽ˉb)

至于STEVEN那张图那几个JUMPING间的距离，我觉得应该是恰好在HYPER DASH的判断范围附近。同时我也认为刚 好可以判断为HYPER DASH的JUMP 是可以被接到的。

至于会这样一会有红果一会没有，纯猜测：我也没做过图，也不知道CTB图怎么生成的，猜可能由于作图时，我们也无法直接生成CTB模式，即使是等距离的JUMP，在系统将OSU的图转为CTB图的时候，可能会有少量像素的偏差，就会出现一会红一会不红的情况。

所以我仍然认为第一个是对的...
收回这句，第一题应该是FALSE

刚弄了一个蛋疼到爆的测试图，就不上图了反正100%接不到的....一个绝对接不到的距离，中间塞了3个NOTE，就都不红了(ˉ▽ˉb)

我觉得第一题和第四题，可能HEBI和MIKHE才是对的。我们过于相信自己的技术和经验以至于依赖它们来判断理论上的事情。第一题和第四题其实应该当数学问题来考虑，刨去水果和盘子的大小把它们都当点看，速度按SHIFT的速度算。举个例子，一MAP有个JUMP，水果下落速度设定为1秒从头到盘子判定线，盘子移动速度达到10cm/s，假设你接到一果子时另一个果子刚掉下来那么理论上只要两果子间距小于10cm,就能接到，超过这个范围就接不到。CTB里盘子的移速和水果下落速度是由MAP的参数决定的就那么几个值。我相信HEBI的说法以老板的水平写出这样的语句毫无问题。史蒂文举的例子只能说明人判断总是有误差的。
至于DT的问题，我一开始以为老板编程的时候有失误没考虑DT的情况以为DT根本没红果，但前天HY1亲自打给我看了，开DT也是有红果的。如果只有NOTE那么开DT也是必然能FC的。但有人告诉我，老板设计红果的时候没考虑高速长滑条。导致高速长滑条没红果。我相信不开MOD都不能FC的话开加分MOD必然也不能FC。实际情况老板没说明我们也不知道，那么第四题到底谁是对的那也只有老板知道。

臥槽我們這個月有三次大型考試 下禮拜又要考了 這禮拜先AFK至11月上旬

关于我截得那张图， 我可以肯定的告诉你他们中间的距离是一样的。
其实我以前也一直以为红果是这样一个原则：当盘子处于极限移动时，jump的距离超过起点和终点的正中间，这时就会触发红果。因为实际上很多处不需要红果的地方反而被加上了红果。
但是就在前几天我那个天国地狱做成之后给mikhe, darksoul还有光叔玩过之后，我发现几个jump即使是玩家反应有点慢，但是看上去确实是不可能接的住的。于是我特意去研究了一下极限跳，结果就是前面的那张图。我现在还留着那张map，有闲心或不怕麻烦的朋友可以去看看。
这是链接：http://puu.sh/mF6
这里我做了3个假设：
第一个是简单测试slider与极限跳：相同距离下极限跳是红果， slider不是。
第二个是和slider一样的位置的极限跳：当极限跳中间加了note，和slider相同距离的跳的红果被消掉了。
第三个就是上面那张截图：相同距离下同样是红果跳，当中间加了note，原本的红果被消掉了。
用截图说明太复杂了。。如果大家真正想了解这东西，还是下载我那测试图，试试就知道了~~

史蒂文你那个图不能作为反例来反驳，因为那跳确实没到极限。无论SLIDER,还是中间加NOTE的情况，我都接到过。红果不代表所谓的极限。这题的关键在于老板建红果时用的数学模型，我们需要知道那模型才能知道现在理论上是不是存在不能接的JUMP。

Why do I find this thread so cute :3

蛋疼的红果相关研究：

我做了一系列的测试图，虽然并不完全，但大致证明了以下与CTB及红果有关的问题：

由于我并没有对所有情形进行测试，而且我也不是很懂作图，所以仍可能有纰漏，若发现请指出。
所有测试不涉及slider,仅仅涉及note
所有测试均在no mod下进行，所以暂时无法解释Double Time Half Time的问题
在DT与HT下的测试结果均与本假设吻合。

1.盘子大小仅与circle size参数有关，从大至小，盘子大小依次为，108,96,84,72,60

2.两个相邻note间极限非红果的距离，与两个note间时间间隔t呈线性关系。

2中距离可表示为：S = kt + X

t 表示两个note间时间间隔,单位为毫秒(ms),并且不会因为模式的变化而变动！
k 仅与MOD相关，在NO MODE下为1，Double Time下为1.5，Half Time下为0.75
X 仅与circle size相关，从大到小，依次为，68,60,53,45,38.
S 即极限非红果距离，为作图时两个NOTE中心连线的距离。

关于几个参数的重要说明：

t，这个时间间隔，不会因为模式的变动而变动！是绝对的
这个t值，就是no mod下的时间间隔！！永远不会变！！
如果两个note，在no mod下的间隔为300ms，当我们使用了double time时，虽然我们实际能够移动的时间只剩下200ms，红果仍然是按我们移动了300ms来判定的！！但是判定红果所用的移动速度却变成了1.5倍(ˉ▽ˉb)
这也就解释了HT,DT和No Mod的红果问题
在这一点上，我不知道老板是就这么设计的还是⑨了(ˉ▽ˉb)

k，虽然确定与盘子移动速度成正比，但是是不是盘子的移动速度，我就不知道了，不过应该是是的吧，怎么想都是的吧，我就是没法测试确认，但是我肯定是这么认为(ˉ▽ˉb)

X，若所有数据均为整型，由于四舍五入的关系，盘子大小的5/8正好为X的数值。
（我也不知道为什么是这么一个奇怪的比率，不过既然这个值已经大于1/2的盘子大小，就使得当三个连续的极限非红果出现时，这三个果子将无法被全部接到）



另外指出：
作图时使用distant snap产生的两个note间的斜率，大于以上所称k，即更简单
作图时使用distant snap产生的一个slider的斜率，小于以上所称k，即更难这行搞错了貌似，请无视

我语言表达能力猪一样，将就看吧(ˉ▽ˉb)

p.s.回到这道题上，我承认我错了，光叔你的和STEVEN的答案是正确的

1.Any combination without sliders can be catched theoretically in no mod. (True or False)
False. Hyper jumps madness in high bpm is impossible.
example http://osu.ppy.sh/b/27638

2.The dropping speed of the fruits is always like HR>DT>No Mod. (True or False)
False DT can be more harder than HR in maps with Aproach Rate 9 or 10. Hardrock can't increase Aproach rate to 10+. That is osu system. so AR1~8 will have such view: HR>DT>No Mod. AR9: DT> HR> No Mod. AR10: DT> HR = No mod. In AR 10 HR will just increase HP drain, discrease circle size and replace fruits placement.

3.When playing a song with HD+FL, you can still see the shadow of the fruits after you get the combo over 200. (True or False)
True

4.Here's the situation: There's a fruit with hyper dash in a song with no mod, but when processing with DT the hyper dash disappears. The jump, which its hyper dash has been removed in DT, also theoretically can be catched. (True or False)
False. Some Hyper jumps are impossible. (some hyper jumps in TAG4 for example)

5.DJ Larto diff of Noisia - Groundhog (Beat Juggle) is theoretically FCable.
I don't know, i can't FC that, but may be someone will be able. so i'll say True.

1.Any combination without sliders can be catched theoretically in no mod. (True or False)
false imo

2.The dropping speed of the fruits is always like HR>DT>No Mod. (True or False)
false
in easy diff, DT is faster than HR, right? cmiiw

3.When playing a song with HD+FL, you can still see the shadow of the fruits after you get the combo over 200. (True or False)
i don't know whether the shadow is so fuckingly small or it is completely can't be seen <_<

4.Here's the situation: There's a fruit with hyper dash in a song with no mod, but when processing with DT the hyper dash disappears. The jump, which its hyper dash has been removed in DT, also theoretically can be catched. (True or False)
false

5.DJ Larto diff of Noisia - Groundhog (Beat Juggle) is theoretically FCable.
i don't know.
