Hello! I'm trying to create a system that creates a directional path of physics forces, like a water or wind current. I would like this path to follow a spline path I've created in the editor, so that I can create multiples of them in a level. The paths are not straight and can be quite curvy. To do the physics part, I've been doing horizontal raycasts along the spline, then applying a force to the object in the direction of the spline. But I don't know how to make this affect particles as well. I can't just do a procedural mesh with a texture because the particles (bubbles in my case) need to respond to objects with physics when touched. How can I properly apply these kinds of complex directional forces to my objects?
