I`ll try to simulate roller coaster cars on the track.
I can set normals, velocity and up vector to points on track.
But there is small thing i cant understand.
How to keep particles on curve, slide them freely (without any offset) with applying forces (velocity, gravity and friction/drag) to them. Is it possible?
Without setting position in UV coords for points. Position node and similar not helping. Edge and attractor forces too.
When velocity is too high - particles fall off the track.
I need points to be on the track until they reaches its end(if it exist)
Keep particles on curve with working forces

You could constraint the particles to a curve using point cloud search in a VOP POP.

Well. There is some progress in this rollercoaster.
I`ll did “something physical” with solver dop. But results are not perfect.
What I have for now - animated point fall from a hill, climb at another hill, that higher than first one, and she didn`t get the top of it, and its ok, but when point turn backward, its velosity magically encreased :shock:
Its happens always when point reverse moving direction.
Can anyone help me with kinematic physics in this hip.
Where is a mistake? Maybe I used wrong physical formulas..
And one more thing, i`ll don`t know where to put a friction or air resistance force, without it velocity encreased in exponent to infinity, and its not good
P.S. sorry for bad English, i`ll hope you people understand it)
