I’m so happy about how this script that generates a roller coaster track from a Curve3D turned out!
You can find the code on GitHub.
Be sure to download track.gd, track_generation.tscn and meshes/track_sleeper_rollercoaster.res and fix the path to the mesh on the code.
The roller coaster will be part of my game horror Delta Kayak , adding to the creepy atmosphere.
Also my immediate thought is that the End of the track when it connects to the Start isnt doing it with derivatives and therefore looks not smooth/shockfree.
