Description
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.

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.

Connects two existing ties with the specified track type. |
(Available types in commands: default, chain_drive, magnetic)

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.
