This is a sub-page of Crypt of the NecroDancer.
This page details content that is unused in current versions of the game (3.0 and newer). Content is sorted into groups based on which part of the game it's in. The Base Game section covers content within NecroDancer.wsp, Assets from Legacy covers stuff in Legacy (Current version uses Legacy's assets for a lot of things), and the rest are for the various mods bundled with the game (called Feature Packs or DLCs).
 | To do: Like, everything.

 | This article is a work in progress. ...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes. Notes: Lots of image needs to be uploaded. |
 | This game is still under active development. Be aware that any unused content you find may become used or removed in the future. Please only add things to the article that are unlikely to ever be used, or went unused for some time. If they do get used, please remove them from the page and specify in the edit summary! |

Content
This section's for stuff you can re-activate via mods, editing the game's code, tweaking the config files, etc.
"dev" Flag
I won't be explaining how to enable this, as it causes the game to bypass some of its integrity checks for leaderboards, and the NecroDancer community really cares about leaderboards.
From what I can tell, its full effects are:
- Allows using unpackaged versions of the game's built-in mods without disabling leaderboards
- Un-hides the Leaderdoard Options section in Misc Options
- Allows using the F4 debug console without disabling leaderboards
- Allows F1 and F4 debug keys to be used without holding shift
- Enables the following additional debug keys:
- F6: If Shift is held, does a performance test, seemingly of rollback, and prints the results to the game's log file.
- F10: If Shift is held, starts the LuaJIT profiler. Otherwise, starts the regular profiler.
- This appears to just freeze the game.
- F11: If Shift is held, stops the LuaJIT profiler. Otherwise, stops the regular profiler.
- Shows the Lag Log, Light and Sprite tabs in the F1 debug menu.
- Allows errors to be blocking during gameStateReset (i think?)
- Allows pressing tab on leaderboard entries to log some info
- Allows watching replays from older versions
- Prevents mod load locations with "dev" set to false from being used
- Allows the player to see while the game is paused with the "Multiplayer Pause" key
- Allows statistics to be tracked while doing anything that would normally prevent them from being tracked (like playing modded)
- Grants access to the "Test" gamemode
Leaderboard Options
To access:
menu.open("settings", {
prefix = "misc.leaderboard",
})
Credits Menu
Was used in pre-3.x versions of Synchrony, but is no longer used.
To access: menu.open("credits")
Gameplay Options Menu
Possibly a leftover from an earlier version before custom rules were implemented.

Balance Tweaks (3.x only)
Balance Tweaks was a feature pack that contained various options to adjust the balance of the game. While it was used in older versions of the game, it went unused for the rest of v3. It was removed completely in v4. According to Marukyu, Balance Tweaks was never completed.
that menu was part of the "Balance" mod/feature pack, which was never actually finished (many of the options simply did nothing).

HalloweenIdeas.md
A document detailing various ideas for the halloween event.
HalloweenIdeas.md
- Lobby shrines - Last One Dancing (Shrine of Glass) - Deathmatch (Boss Shrine) - Trick or Treat (Shrine of the Feast) - Toggle Raveyard generator (Shrine of Space) - Mechanics - All enemies drop candy in addition to gold - Candy drops are based on the enemy's natural gold drop amount - No coin multiplier is applied when candy is dropped - Objects - Jumpscare chests - Some chests do not contain items, but enemies, minibosses or even bosses - Spooky barrels - Some barrels start rolling themselves at any (non-adjacent) approaching player - Sarcophagi as player spawn points - Players respawn from a random sarcophagus (instead of at a random point on the floor), replacing the next enemy - Walking in any direction frees the player from the sarcophagus, even if the direction is obstructed - Mountain of Candy - Dropped by bosses, attackable like a crate - Yields candy multiple times per hit: 30, 20, 10, 5 - If multiple players hit it in the same beat, all players get the full amount of candy - Enemies - Skeleton Tombkeeper - Periodically picks up the sarcophagus it spawned from, and carries it in a random direction by a few tiles - Goblin Trapper - When within 3 tiles of a player, leaves behind a trail of traps - Pink Leprechaun - Spawns when a candy pile of 25 or more is left alone for 7 beats - Steals all candy on hit, then disappears - Leaves behind a trail of 5 candy per tile, with the same rules as the regular Leprechaun - Drops the Candy Magnet on death, on top of a pile of 30 candy pieces - Can spawn once per floor - Events - Candy Leak - All players leave behind a trail of candy - Players can only pick up the candy trails left behind by other players - Items - Goodie Bag - Permanent backpack slot item, replaces the default holster in Halloween mode - Contains collected candy and allows eating 10 candy to regain half a heart - Pumpkin Crown - Slotless - Indicates top-score, automatically travels to the highest-scoring player using a visual animation - Candy Magnet - Dagger-range melee weapon - Steal 1 candy per non-shielded hit against players or enemies - First extra candy is free, further stolen candy is deducted from the monster's natural drops - Ghost Costume - Armor slot - Restricts vision like Ring of Shadows - When killed while wearing it, no candy is dropped, and the Ghost Costume is passed on to the killer - Disintegrates when wearer is killed by an enemy - Shovel of Shove - Pushes walls instead of digging them - All walls in a row are pushed simultaneously - When a wall is pushed into an obstacle (Shop wall or level border), the furthest wall in the row disintegrates - When a wall is pushed into a player or enemy, damage is dealt based on the wall's dig strength - Infernal Boots - Leaves behind a short-lived trail of hot coals - Grants immunity to hot coals (both permanent and temporary) - Spells - Possession spell (looks like a lantern) - Temporarily take control of a monster or player - Ethereal spell (looks like a wraith) - Temporarily phase through walls for 8 or 16 beats - Can be extended by staying in the wall, but starts dealing suffocation damage until leaving the wall - Necromancy spell (looks like a skull) - Undead enemies (skeletons, zombies) leave behind bone piles, which can be resurrected - The spell resurrects bone piles in a Ring-of-Shadows-like radius around the player - Resurrecting a bone pile creates a Red Skeleton, which mirrors the player's movement and drops no candy/gold - Invisibility spell - Temporarily become invisible for 4 beats - No longer targeted by enemies or visible to other players - Visibility is broken upon being hit or upon digging - It is not possible to attack or use items during invisibility - Last beat of invisibility is telegraphed - Projection spell - Creates fake, non-colliding ghost copies of the player that mirror the player's movement - To the caster, they appear semi-transparent and can be walked through - To other players, they appear as exact copies of the player and can be attacked - To monsters, they appear as a valid target - They despawn when hit, when bumping into an obstacle, or automatically after a few beats - Curse spell (looks like a weird Transmute Spell) - Curses nearby entities on adjacent tiles in various ways - Cursing an enemy causes it to split into two copies of itself upon death - Cursing a mushroom light causes it to turn into an angry giant mushroom light on the next hit - Cursing a shopkeeper causes them to start chasing players without attacking - Cursing an item causes it to disintegrate on pickup, forcing the player to step off and pick up the old item - Cursing a bomb turns it into what seems like a normal bomb item, which immediately drops a lit bomb on pickup - Cursing a chest causes it to spawn an enemy or miniboss instead of an item - Cursing an urn causes it to spawn two minibosses and a boss instead of three items - Cursing a wall causes it to spawn a skeleton when dug - Cursing a trap causes it to stick to the first player to step on it, leaving behind a trail of traps - Cursing a travel rune causes it to teleport players to a random location on the floor - Cursing a player causes them to get teleported to a random location on the floor - Levitation spell - Grants temporary levitation for 16 beats
Assets from Legacy
3.x pulls most of its assets (music, sounds, sprites) from the Legacy version. Most of the unused assets from Legacy also go unused in 3.x.
Sprites
| To do: somehow auto-gen a more comprehensive list? also upload the empty cursed heart sprite |
| Image | File Name | Notes |
|---|---|---|
| File:CryptOfTheNecroDancer-Legacy-cursed heart empty.png | cursed_heart_empty.png | While this was used in Legacy (albeit only when save editing is involved), it goes unused in 3.x due to differences in how cursed health (and health rendering) is implemented. |
Sounds
Here's a list of sounds from Legacy that aren't used in 3.x. This list was auto-generated by listing all sound files in the game that aren't in any sound groups.
| To do: Upload all of the ones that aren't duplicates or completely silent. Add notes for the ones that need it. Maybe make this table collapsable somehow? |
Interestingly, these two unused sounds are assigned to sound groups:
| Audio | File Name | Sound Group |
|---|---|---|
| sfx_countin_other.ogg | countinOther | |
| sfx_countin_beat1.ogg | countinBeat1 |
These may have been intended for something similar to 3.x's unpause count-in.
