Splinecart
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.



Splinecart

This mod adds a new type of rail block that can be used to create smooth curved railways for minecart roller coasters.
Originally made for ModFest: Carnival
Getting Started
- Place a Track Ties block on any face of another block.
- Right click the track ties to rotate them.
- Important: Track ties have a "forward" direction, as indicated by the sequence of dark arrows on the block. This determines which direction outgoing tracks will originate from, and incoming tracks will end in.
- Place a second Track Ties block in an appropriate orientation, elsewhere.
- Use a Track item on the first Track Ties block, and then on the second one to create a track connecting them. The order that you click on each track tie block matters.
- Use vanilla rails to run a minecart into the first track tie block.
Track Types
- Track: A regular track that minecarts can travel along
- Chain Drive Track: A track that always carries minecarts forward. Can be used to move minecarts up steep inclines.
- Magnetic Track: A speed control track whose strength is controlled by the redstone signal powering its track tie. Can be used for powered launches or braking segments. Does not work well on steep inclines.
Motion Sickness Warning
- If you are prone to motion sickness, run the following command before riding a Splinecart track:
/splinecartc config rotate_camera false - Splinecart features jarring camera rotation (see Gallery for example) that may cause motion sickness or affect photosensitive users.
- Running the above command prevents the camera from rotating while riding Splinecart tracks to try and reduce this risk.
- Further ways to reduce motion sickness include enabling third person mode in addition to what is described above.
- You can re-enable camera rotation with
/splinecartc config rotate_camera true.
