Editing Level Editor (section)

==Trivia==
*A level can only be verified if it is completed in normal mode without a Start Position. All user coins, if included, must be collected (although not all in a single attempt).
**However, the initial release [https://forums.toucharcade.com/showpost.php?p=2942594&postcount=94 allowed practice mode to be used to verify levels].
*Prior to Update 1.8, level data was stored in base-64 format. Now it is encoded in a different format, probably so it cannot be decoded as easily as before.
*Prior to Update 2.2, an example song ID could be found if the player clicked the "Help" button in the custom song selection menu. The ID, 568699, is the Newgrounds song ID for "[[Hexagon Force]]" by Waterflame.
*In Update 1.9, the Geometry Dash editor had 5 buttons: Copy, Paste, Copy and Paste, Edit Object, and Deselect. However, the Geometry Dash Steam trailer shows an editor with four buttons: Copy and Paste, Edit Object, Deselect, and Edit Group.
**The Edit Group button was not introduced until Update 1.921, suggesting that the version of Geometry Dash used in the Steam trailer was a development version.
*In Update 2.1, all of the colour triggers (BG, Ground, Ground2, Line, 3DL, Obj) were merged into one colour trigger. However, original colour triggers are still in-game to keep 2.1 and newer updates compatible with older levels.
**The only exception is the BG trigger, whose "Tint Ground" feature, which also coloured G1, is no longer accessible; though BG triggers from previous updates that had this option selected still work.
*In Update 2.1, colour channels 1,000 through 1,007 and 1,009 through 1,012 were reserved for BG, Ground, Line, 3DL, Object, Player Colour 1, Player Colour 2, Light BG, Ground 2, Black, White, and Lighter respectively; attempting to use them would crash the game. Despite the bug being "fixed" in Update 2.11, players can still type in colours past 999; colours after 1,012 crash the game due to out-of-bounds edits.
**In Update 2.2, colour channels 1013 and 1014 are reserved for Middleground 1 and Middleground 2, respectively. Colour channel 1008 remains unused.
*The version of the orange teleportation portal introduced in Update 2.0 does not have a button in the editor, as it is automatically placed above the blue teleportation portal along its y-axis. It is bound to the blue entry portal by necessity of its function and consequently cannot be independently moved along its own x-axis.
**In Update 2.2, a new orange teleportation portal was introduced, which ''can'' be independently placed on the x-axis. A second blue teleportation portal was also introduced, which works in tandem with this new variant.
*The second rainbow 26.5° slope is split up into two blocks for no known reason.
*All the 2.1 slopes appear in the first tab for no known reason.
*When the "Dynamic Level Height" option is not selected, the player is killed if they exceed an elevation of roughly 88.5 grid spaces above the ground height.
*When selecting teleportation portals, the "group parent" option is replaced with a "smooth ease" option. When this option is checked, the camera will slowly pan to the exit portal, rather than panning instantly.
*The message "You can't create more than 100 custom objects" is misleading, as the actual custom object limit is 50.
*2.1 uses RGB-4444 for gradients, 2.2 uses RGB-8888 for gradients.
*As of 2.2, level descriptions have a limit of 180 characters.
**In 2.1, level descriptions had a limit of 140 characters.
*The editor is an '''advanced''' feature in Geometry Dash. View the [https://www.robtopgames.com/files/GDEditor.pdf Editor Guide] for more details. A '''lot''' more details.
