If you would like to make the curves for the intersection flush with the sides of the road, you can find out where the lines intersect, and set that as the point for the Bézier curve, which will give you a smooth transition.

Ok, I tried following this tutorial but I'm having a rly hard time doing it because there is a lot of stuff you don't show, for example the functions from the overlay class or create new variables or parameters to functions and not even show or mention them, create structs but not showing where they are placed, etc.. I was finally excited to see how to make roads with this package cuz there is no other tutorials on how to do it, but you're making it hard by not showing everything.

And here am I, who spent a year making my own easy to use spline package. I felt I needed to fill that gap in Assetstore. Although there were some spline packages already, they all were Monobehavour based. I wanted a spline as a serialized object with it's own editor built into property drawer. But now we have this. But I think I still have more features in my BezierZ.

But my curve has interpolation built into it. So I might do it as a separate class so it would be more versatile.

Oh, I feel you. Okay, I didn't write a whole asset from scratch, but I picked up the SplineMesh asset like 10 months ago and rewrote it heavily so that it uses Burst and jobs because I needed quite good performance for the mesh generation. Then I had a look at Unity's asset and recognized that it would be too much work for me to switch the spline asset 🥴😆.

I don't think it is a "hacky" solution. The "internal" specifier is only there to ensure that no one will make use of internal api accidentally. There are also other ways around it, but these make use of relfection. The assembly reference is in fact quite a nice way for doing it.

With it i generate one or multiple crosssection(s) of a road and "sweep" them along road splines and the result is a 3D modular RoadMesh that can be brought by HDA into any engine.

@fokeyjo Жыл бұрын
This was a really great video, well worked out. I was looking into this for a project. I hadn't got that far (and I probably would've run away at the point it got to UV mapping 😆), but I thought it might be slightly simpler for working out the intersection mesh points by having the original spline lines joining at the intersections, because then you have the perfect centre point for the junction. All the road termination points would be known from that centre (each road ending just has a distance back along its spline, and I think you can calculate it as another poster points out) and you'd even know if they were concave/convex from the angle between them being over 90. I'm assuming the spline near the junction is pretty straight (I was doing this with straight lines coming into junctions).
@user-cz4kb5uq9eАй бұрын
Technically in Houdini you'd do the same thing but using VEX instead of C#. There are, of course, some tools that allow to generate a spline base road without writing a code, but as soon as you go into all this junction stuff it's just much more efficient to generate it by code. So basically it is like replace C# code with the HUGE paid plugin to be able to do the same but in a different programming language 🤣.

This is the biggest nightmare of Unity. Something that should be given out of the box (and it is in other engines) you have to reinvent yourself like a wheel and then fight with the engine to make it work. Or of course, you can always buy a working asset from the store, how typical for Unity's new business model. Great video! Is not about you is about Unity.

Hi there, this is great, thanks so much for the video! I have a question, and my knowledge of unity is very limited but Im thinking of developing an AR racing car game that uses splines to auto generate a mesh/race track in any indoor space. How I imagine this is the user scans their living room using their camera and the splines respond to the various pieces of furniture to create the race track. From what I get here in your video, the splines still need to be built and cannot just procedurally sort of 'spawn'? Am I correct in this assertion? Also do you think this would be possible for me to do like you without using houdini? Thank you!
