Object on Spline Movement System that has physics. Is this possible?

[DC_knights11 (DC_knights)]

Hey all!
I am still quite new to game dev. I want to make a custom movement system that moves objects alone in a spline but incorporates physics such as momentum. This is for a train game; ideally, when the player adds additional cars, it would significantly affect gameplay.

I’ve tried a few approaches but they all end up being glitchy.

Any Ideas?

See if this helps:

Make a Ground Rail with Spline

On the most fundamental level: [image] check the inclination of the spline with dot product accumulate this value - that’s the speed use speed to progress through a spline You’ll need to add friction as this preserves energy as perfectly as frame time allows it. And input. And a gazillion other things that makes it a game.

This is faking physics. Good enough or nah?

Oooo thank you for responding. I will have to give that a shot as soon as I can and let you know what happens!
