Splinecart

Splinecart adds smooth, realistically curved railway tracks (composite curves / splines) to Minecraft. Minecarts travel on them without jerking, with full banking and speed physics.

Main elements and mechanics

1. Track Ties

• Wooden (Wood Track Ties), Steel (Steel Track Ties), and Classic:
  • Can be placed on blocks and in mid-air.
  • Automatic alignment to look direction: floor (down), wall (forward), ceiling (up).
  • Empty-hand click rotates the tie.
  • Regular ties act as detector rails (emit Redstone signal 15 while a minecart passes).
  • Steel ties generate a third powered rail plus support pillars; wooden ties create wooden beams and posts.

2. Connecting tracks and variants

• The Track item joins two ties into a smooth path.
• Regular Track: standard smooth riding and corner smoothing.
• Chain Drive Track: pulls the minecart at constant speed uphill (ideal for roller coasters).
• Magnetic Track: when powered by Redstone it accelerates sharply; when unpowered it brakes the minecart to a stop even on steep slopes.
• Seamless transition with vanilla tracks: a minecart smoothly enters from splines onto regular rails and vice versa without losing momentum or camera rotation.

!switch

3. Turnouts / Switches

• Two tracks can leave or enter a single tie at the same time.
• The tie automatically becomes a Redstone-controlled switch:
  • State 0 (no signal): minecart follows the main track (1st exit).
  • State > 0 (Redstone powered): minecart immediately turns onto the alternate track (2nd exit).
  • Detector-rail function is disabled on a switch — lever/dust state changes take effect instantly, even with a whole train of minecarts following one another.

Commands (/splinecart)

Command	Effect
/splinecart banking <on | off | toggle>	Enables/disables track and minecart banking on curves.
/splinecart supports <none | wood | metal | steel | auto>	Sets the style of supports and pillars built under new tracks.
/splinecart build line <x1 y1 z1> <x2 y2 z2> [type] [supports] [banking]	Automatically places and connects a straight track segment between coordinates.
/splinecart build path <pos1> <pos2> ... [type] [supports] [banking]	Builds a continuous multi-point route through the given coordinates.
/splinecart connect <x1 y1 z1> <x2 y2 z2> [type] [supports] [banking]	Connects two existing ties with the specified track type.

(Available types in commands: default, chain_drive, magnetic)

!track supports

All four player-obtainable items have shaped crafting recipes in Survival. The Track Follower is a hidden entity spawned by tracks and is not crafted.

!rollercoster

Track Description: Links two Track Ties blocks together.

Unlocks when you pick up a Rail or Iron Block.

Crafting (makes 4): [Iron Block] [Rail] [Iron Block]

---

Chain Drive Track Description: Track variant that pulls minecarts.

Unlocks when you pick up an Activator Rail, Chain, or Iron Block.

Crafting (makes 4): [Iron Block] [Chain] [Activator Rail] [Chain] [Iron Block]

---

Magnetic Track Description: Track variant that accelerates or slows minecarts.

Unlocks when you pick up a Powered Rail, Iron Block, or Copper Block.

Crafting (makes 4): [Iron Block] [Copper Block] [Powered Rail] [Copper Block] [Iron Block]

The magnetic track's strength follows the redstone signal powering its Track Ties block.
