MCoaster
by 1HelloHello
MCoaster is a Fabric transportation mod for building roller coaster tracks in smoother, more varied layouts, with tools for heading, pitch, banking and relative orientation.
What it does
Track is laid with markers placed in the world, and the mod adds tools that control how the track moves: heading tool changes the horizontal direction, pitching tool changes whether the track climbs or descends, banking tool changes how the track leans through curves, and the relative orientation tool sets heading relative to a pitch already applied. Only the elements a build needs have to be set, so simpler sections stay simple.
The mod is a fork of Splinecart and is open source under the MIT License. Coaster friction is set per track, with the default at 20 and 0 meaning no friction is felt by the cart. A trigger output option hides status messages when triggers fire, and shift right click removes stored triggers from a marker. Most builds use two markers that swap a power setting back and forth, and a chain lift can be turned off with a single setting.
MCoaster requires Fabric API, Mod Menu and YetAnotherConfigLib (YACL). It is client and server, so the server and every player need it, and files cover 1.21.2 – 1.21.4, with 1.0 for 1.21.4 as the latest Fabric build, released on 2025-12-15.
Key features
Heading tool
Changes the horizontal direction the track travels, so layouts can turn in the plane of the ground.
Pitching and banking tools
Pitching sets whether the track goes up or down, and banking sets the lean through curves.
Relative orientation tool
Sets heading relative to a pitch that has already been applied, reducing the number of elements a complex turn needs.
Coaster friction setting
Controls the friction a cart experiences on the track, with 0 removing it entirely.
Trigger controls
A trigger output option hides messages, and shift right click removes stored triggers from a marker.
