Server Level Resource

Level

A level is a playable object in Geometry Dash, namely coming with data that explains on what it is, and the string that the client interprets, known as a level string.

A typical level server response is structured with a key:value:key:value pairing and is then split with a |

keep in mind that the value for key 4 will be replaced with {levelString} as it is too big to show

Each key is tied to a component within the client and the value sets data for the specific component.
A list of all known keys can be found in the table below

Level Object

Keys indicated with an asterisk (*) are only returned from the downloadGJLevel22 endpoint.

Level Structure

Key	Name/Value	Type	Description
1	levelID	Integer	The id of the level
2	levelName	String	The name of the level
3	description	String	The level description, encoded in base64
4*	levelString	Level String	All the data for the level
5	version	Integer	The version of the level published
6	playerID	Integer	The player ID of the level author
8	difficultyDenominator	Integer	Returns 0 if the level is N/A, returns 10 if a difficulty is assigned. Historically used to be the amount of people who have voted on the difficulty.
9	difficultyNumerator	Integer	The nominator used for calculating the level difficulty. Divided by the denominator to get the difficulty icon. Nowadays just 0 = unrated, 10 = easy, 20 = normal, 30 = hard, 40 = harder, 50 = insane. Can be also used to determine the demon difficulty as a side-effect of the voting system. Historically used to be the sum of stars from all votes
10	downloads	Integer	The amount of times the level has been downloaded
11	setCompletes	Integer	The Number of people who have completed a specific level removed in update 2.1
12	officialSong	Integer	The official song number used by the level, if applicable
13	gameVersion	Integer	The GD version the level was uploaded in. Versions 1.0 to 1.6 use version numbers 1 to 7 respectively. Version 10 is 1.7. Otherwise, divide the version number by ten to get the correct number.
14	likes	Integer	likes - dislikes
15	length	Integer	A number from 0-4, where 0 is tiny and 4 is XL
16	dislikes	Integer	dislikes - likes
17	demon	Bool	If the level’s difficulty is demon
18	stars	Integer	The amount of stars rewarded for completing the level
19	featureScore	Integer	0 if the level is not featured, otherwise a positive number. The higher it is, the higher the level appears on the featured levels list.
25	auto	Bool	If the level’s difficulty is auto
26	recordString	String	appears in the GJGameLevel parser but is unused
27*	password	Encrypted String	The password required to copy the level. It is XOR encrypted with a key of 26364
28*	uploadDate	String	The approximate date the level was uploaded on
29*	updateDate	String	The approximate date the level was last updated on
30	copiedID	Integer	The ID the of the original level (if the level was copied)
31	twoPlayer	Bool	Whether the level uses two player mode
35	customSongID	Integer	The ID of the custom Newgrounds song used in the level
36	extraString	String	The extraString passed when uploading the level. Its use is currently unknown
37	coins	Integer	The number of user coins placed in the level
38	verifiedCoins	Bool	If the level’s user coins are verified (silver)
39	starsRequested	Integer	The star value requested for the level
40*	lowDetailMode	Bool	If the level has a low detail checkbox
41*	dailyNumber	Integer	Daily/weekly levels only. Returns which daily/weekly the level was (e.g. the 500th daily level). Subtract 100,000 if the level is weekly
42	epic	Integer	The epic rating for the level. 0 = none, 1 = epic, 2 = legendary, 3 = mythic.
43	demon Difficulty	Integer	The difficulty of the demon rating. 3 = easy, 4 = medium, 0 = hard, 5 = insane, 6 = extreme. Can also be used to determine the level difficulty non-demons had before rating as a side-effect of the voting system.
44	isGauntlet	Bool	if the level is in a gauntlet
45	objects	Integer	The amount of objects in the level, used to determine if the level is considered “large”. It caps at 65535
46	editorTime	Integer	the total number of seconds spend on the current copy of a level
47	editorTime(Copies)	Integer	The accumulative total of seconds spend on previous copies of the level
48	settingsString [Unused]	String	It was found in early 2.1 coming from the servers and was removed shortly after. The December 2019 2.2 Leaks however have information regarding it showing that it is called settingsString but, there is no information regarding its usage
52*	songIDs	Comma-Separated List	The list of all song IDs in the level, separated by commas
53*	sfxIDs	Comma-Separated List	The list of all SFX IDs in the level, separated by commas
54	unknown	Integer	Unknown value, perhaps robtop-only? (corresponds to k106 in the save file)
57*	verificationTime	Integer	How long the level took to verify (in frames, assume 240 FPS)

Trivia

• The getGJLevels endpoint returns the keys 46 and 47 however they aren’t actually correct (as of 2.1)

• Keys 46 and 47 are also capped at the 24-bit integer limit so any time longer than around 4660 hours won’t be accurate

• key 45 caps at the 16-bit integer limit so any level with more objects won’t be accurate

• Key 57 caps at the 24-bit integer limit so any time longer than around 465 hours won’t be accurate
