General guidelines/一般性指南

1. Perfectly timed. This means that your BPM and offset are spot-on, sliders end when they should, and notes are generally following a rhythm which is comprehendable by a player./必须被很好的测好时间. 这意味着你的bpm和offset必须是正确的，滑条在合适的地方结束，note也应该遵从一个节奏来使得玩家可以读懂。
2. Make sure you can pass the song./确保你自己做的图自己能玩。
3. Each map set must have at least two difficulties, one of which must be below a 3-star difficulty level. This is so that players of all levels of experience are able to enjoy maps of the songs they love. A map set should not have more than two difficulties in the same difficulty level (not based on stars, but on how the map "feels"). That is, a map set can have no more than two "Insane" difficulties, etc. The only exception to this rule is Taiko difficulties. That is, a map set can have two Insane osu!standard difficulties in addition to a Taiko-specific Insane. Finally, no map set should have more than 6 difficulties total. /每一张图至少需要有两个难度，其中一个必须是三星以下（实际上现在已经是有个足够简单的难度就可以了）。这么做是为了让所有水平的玩家都能够玩到他们喜欢的歌。一张图里同一等级的难度不能超过两个，这个难度不是取决于系统分配的ENHI，而是打起来如何。以及，太鼓难度并不计算在内，这就意味着一张图可以有两个Insane和一个Taiko-Oni。总之，全部难度数加起来不能超过六个。
4. CTB-specific difficulties cannot be included in mapsets. However, you may add a link in your beatmap's thread to a CTB difficulty./接水果难度是不能被rank的，所以说不要把它丢到你的图里，当然你是可以把接水果难度的链接丢到Creator's Words之类的地方里的。
5. Beat placement generally follows the time-distance-equality rule (holding Alt while placing beats enforces this). This means you shouldn't have some fast notes with huge distance between them followed by closely placed but slow notes. This gets really confusing if the player isn't the person who designed the beatmap! Having some logic to the placement should be one of your goals./放note的时候应该绝大多数遵从时间上的距离 也就是distance-snap（按着alt放note来强制使用这个 注：如果你edit里已经使用了distance-snap，那就不用理这个了）。这表示你不应当在时间上紧挨着的note之间放置超大间距，而是选择在时间间隔较长的地方使用。否则的话会让作图者以外的人很困惑。在note的放置上有一点设计，这应该是你努力的方向之一。
6. No two hitobjects on the same tick. This includes hit circles, starts and ends of sliders and starts and ends of spinners./不要再同一个时间点上放置两个note，这个包括圈圈、滑条的开始/结束点，和spinner的末尾（吐槽：卧槽那岂不是spinner的开头可以搞重叠了?）。
7. Stack leniency should never be set to a point where stacking no longer occurs. It is there for advanced patterns where stacking is not wanted, but should not be changed in most every map./Stack leniency值不能设置成所有的note都不会堆叠起来。这个值是为了一些不使note叠起来的进阶花样，但在通常情况下，不要更改这个数值。（注：关于0.2能不能rank，目前的答案是可以，如果0.3和其他值都不能满足你的要求的话--比如slider和note, slider和slider之间叠来叠去, 有时候不用0.2不行）
8. A maximum of three slider velocities may be used. This includes 1x, so for example you can have a single map using 0.6x, 0.8x, and 1x, or 1x, 1.5x and 2x./滑条的速度最高是三个，其中包括1.0x速度。例如你可以使用0.6x 0.8x 1.0x或者1.0x 1.5x 2.0x。（注：请尽量减少不必要的速度变化）
9. Please don't use non-inhereted (BPM) timing changes to adjust slider speeds./不要用红线来改slider速度
10. The song should not be too long! Aim for 2-3minutes maximum. Anything longer gets tiring. If you need help editing a song down to length, feel free to ask in the Beatmap Help forum. Use TV versions of opening/ending themes where possible./选曲不要太长！2~3分钟就行了，再长就有点累人了。如果你需要剪切一首歌，尽管到Beatmap Help forum里求助。请尽可能用TV版的OP/ED。（注：短点没坏处，长曲子目前的问题主要是分数）
11. The song audio file should also be of reasonable quality. Try and source mp3 files yourself - ripping them from a streaming video site often results in low quality audio with high file sizes. The bitrate of a beatmap's audio file should be no lower than 128kbps and no higher than 192kbps. If you are having trouble acquiring an appropriate audio file, contact one of the more audio-savvy BAT - they will be more than happy to find one for you./歌曲的音频文件应当有不错的质量。请尽量自己找方法来取得mp3/ogg文件——从视频网站里下视频再转音频一般是很烂的质量。音频文件的比特率应当在128kbps~192kbps之间。如果你找不到适合的音频文件，那么请联系那些存了很多歌的BAT成员，他们很乐意为你效劳。
12. Use breaks where possible. Even if they are only 5-10 seconds, it allows a bit of recovery and hand repositioning for the players./在可能的地方放置休息段，即使只有5~10秒，对玩家来说恢复和调整姿势也足够了。
13. Try to keep osz files under 10mb, or 20mb if you include video (please remove the audio track from video files to save space. It is recommended for the video's dimensions to not exceed 800x600.)/尽量使最后的osz文件大小小于10MB，如果有视频的话总大小请控制在20MB之内（请把视频的音频部分移除来减小体积。推荐你使用800x600以下的分辨率）
14. In case any difficulty can give a maximum score of over 10 million points (check this by pressing F5 in the editor to test play the map), try to lower it. Do not resort to dropping the slider tick rate to reduce score. If you insist on keeping it as is, there are two choices. If you want it in the ranked category, the beatmap needs to be approved by an experienced BAT specifically. Otherwise, it can be approved. The only difference is that an approved map does not count towards your ranked score. You still get a scoreboard and everything./如果有难度的分数高于1000万，那么请尝试去降低它。不要企图用降低slider tick rate来降分。如果你想要就这么rank这张图，那么你有两个选择。一个是找一个熟练的BAT成员来看，剩下的则是app这张图。app的图和rank的图只有一个区别，那就是app的图打完了不计入你的ranked score中，但是每张图依然有自己的分数板以及其他东西。（注：1000万的确有点夸张，但是1600~1700万应该是最高界限了...再高就妥妥的app了）
15. Do not overuse kiai time (general rule is one toggle per minute of playable length). Do not use kiai time just for fountains unless you are doing this extremely rarely. Kiai time is meant to accent chorus sections. You can toggle it off and on halfway through the chorus if that looks good, but using it constantly every 4-8 beats is just stupid./不要到处用KIAI。请尽在高潮部分使用KIAI，除非你极少次数地在其他地方使用。如果看起来不错的话，你可以在副歌部分关闭再打开它。不过请记住，每隔几个note就开关一次就太蠢了。
16. Don't make skinned elements larger than template skin dimensions. This is especially true for combobusts./请不要让自己做的皮肤零件大于模板皮肤里的。尤其是comboburst。（注：宽不要超过500像素，高不要超过767像素）
17. Make sure if you are using any elements created by other community members in your beatmap (video, skins, so on) that you ask for permission beforehand! Respecting the work of others is paramount and most people will be delighted to have their work featured in your projects./如果你用到了任何一个由其他玩家制作的东西（例如视频，皮肤等），请在此之前寻求许可！主要出发点是尊重他人的劳动成果，而且多数人都很乐意自己的作品出现在你的项目中。
    
    
    General score guidelines /分数指南:
    <10m = Great!/ <1000万 = 很好
    10-12m = Can the mp3 be cut to make it shorter and more fun? if not, then check with any experienced BAT but not peppy./ 1000万~1200万 = 剪一下歌会不会让你的图时间更短更有趣？如果不是的话，找任何一个不是老板的BAT来确认一下。（注：现在是完全没问题的）
    12-20m = Same as above, and check difficulty is hard enough that score is not so attainable./ 1200万~2000万 = 和上一条一样（注：但是标注可不一样了），而且保证这个分数符合它的难度。（注：2000万太吓人了... 还是1600~1700万是极限）
    20m+ = rare cases, for insane difficulties which have max attainable scores <=15m/ 2000万以上 = 很少出现，对于insane难度来说，小于1500万都是可以接受的。
    
    
18. You must use hit sounds. Without these things get way too monotonous as you are throwing away one of the main elements of variation present in mapping./你必须使用hitsound。没有这些的话就太单调了，因为你放弃掉了作图中的主要花样。（注：这个大概是最能出彩也最容易被新手遗忘的地方）
19. You must have a background image to get your map ranked./必须有个背景图。
20. No obscene imagery in background image/storyboard/video content. This includes nudity or near-nudity. Keep things PG, suitable for 12+./背景图/SB/视频中不能出现和谐物（包括果体和近似果体）。所有的东西必须12+
21. Maps that use flashing colours in the storyboard MUST be labelled with a warning at the top of the forum thread, or preferrably in the storyboard before it occurs./闪啊闪的图必须有警告，也就是epilespy warning及论坛讨论串里应当有提示。
