Minecart

The Convict riding a minecart

Minecarts are environmental objects that appear exclusively within the Black Powder Mine in Enter the Gungeon. Moving on pre-determined sets of rails, they can be ridden by both the player and enemies.

Behaviour

A Red Shotgun Kin and Bullet Kin riding minecarts together.

Minecarts sit entirely still while absent a rider. If the rider is a player, the motion of the minecart is determined by the players movement input direction, while if the rider is an enemy or non-enemy object, the minecart will move in a predetermined direction along the track, at a constant max speed. If a minecart pushes against an empty minecart on the same track, the empty cart will inherit the momentum of the moving cart.

The player can enter a minecart by approaching it and interacting, and can dismount the same way- or by dodge rolling in a specific direction. If the player does not hold a movement direction while dodging in a minecart, they will dodge roll in place without leaving the cart. This is useful for avoiding damage while traversing tight minecart tracks.

If a minecart collides with an enemy while travelling at a speed greater than 2 tiles per second, it will deal 50 damage to that enemy. Minecarts driven by enemies will not damage other enemies, or the player, regardless of their speed.

Certain enemies have a special behaviour, which prompts them to seek out and enter their nearest minecart. Once inside a minecart, these enemies cannot dismount. A full list of enemies that can ride minecarts is as follows;

Bullet Kin Red Shotgun Kin Cardinal† Shroomer Ashen Bullet Kin‡

Mutant Bullet Kin† Fallen Bullet Kin‡ Mutant Shotgun Kin† Ashen Shotgun Kin† Shotgrub†

Executioner†† Sniper Shell Professional Pirate Bullet Kin† Western Bullet Kin†

Pirate Shotgun Kin† Green Bullet Fish† Blue Bullet Fish† Knight Bullet Kin† Candle Guy† Brollet†

^† This enemy cannot spawn in the Black Powder Mine, so this behaviour is functionally unused.
^‡ This enemy does not spawn naturally in the Black Powder Mine, but can be spawned with the Lament Configurum.
^†† This enemy does spawn naturally in the Black Powder Mine, but does not spawn in any rooms containing minecarts. It can, however, be spawned with the Lament Configurum.

Minecart Turrets

Some minecarts contain pre-placed miniguns, referred to as Minecart Turrets. These turrets will continually fire at the player throughout combat, becoming inert after all enemies in the room have been killed. They are not considered enemies, and cannot take damage.

• The Unity GameObject of Minecart Turrets is called Rotato.

Explosive Barrel Minecarts

Exactly one room layout in the Black Powder Mine contains two rails, each of which connect directly to the walls. Minecarts containing explosive barrels will constantly spawn out of one wall opening, travel along the track, and enter the other wall to despawn. The explosive barrels in these minecarts behave identically to regular explosive barrels, with the exception that they cannot be rolled, kicked, or destroyed by dodge rolls.

If an explosive barrel in a minecart explodes, it will deal damage to all nearby enemies and player, as well as destroy the minecart containing it.

It is unknown why explosive barrel minecarts are only used in a single room layout.

Tracks

The routes that minecarts travel are placed as part of the design of each room that contains them. During floor generation, the game will generate rails along these predetermined paths, following a few rules. These minecart tracks are mostly visual, outside of showing ahead of time the path that a minecart will take. They do, however, count as walkable floor, and can therefore be used as platforms over pits.

Some room layouts contain only rails without minecarts, for either aesthetic reasons or for their aforementioned purpose as diegetic pit crossings.

Tracks can only generate on the Black Powder Mine. If minecarts are generated on other floors, the rails will be invisible, and will not create walkable pit crossings. Additionally, some minecart tracks in the Mines have had their rails disabled, resulting in magical seeming floating minecarts.

• 

  A rail passing over a pit, forming a walkable crossing.
• 

  Two tracks terminating over a pit, creating the appearance of a broken rail
• 

  Tracks that enter into walls will create visual openings. These openings cannot be entered, however.

Other Appearances

• A Keybullet Kin riding a minecart can be seen in the background of promotional art for the Supply Drop Update, illustrated by Max Grecke. This is not a behaviour observable ingame.

Notes

• Minecarts have a configurable max speed and acceleration rate. The default max speed for most minecarts in a vanilla game is 9, reached over 1.5 seconds of acceleration.
• Enemies in minecarts will not deal contact damage to the player. Additionally, the player is immune to all contact damage while they themselves are in a minecart.
• Minecarts were teased in a tweet from Dodge Roll Games on 04/072015, featuring a gif of a Bullet Kin fruitlessly chasing The Convict in a minecart. The text of the accompanying tweet was "He catches up eventually..
