Adaptive pathfollowing CSGPolygon

simLC

Hi, I learnt how to make a road with this video :

To summerize, you have to : - make a path with a 3dcurve - extrud with a CSGPolygon using pathfollow - modify the extruded polygon to make a flatter rectangle.

My point is that this doesn't allow you to change the shape of the polygon along the path and I want to know if it's possible? For example, I would like to make a one lane road that widens on both sides into two lanes just like on the picture.

My question focus on the shape of the road, not on the texture/material of the road.

Thank you in advance for your help :)

Depending on your game, one way you could get around the issue is to use a separate path 3D node for each road with different widths. Then you could place a mesh/CSG-mesh that connects the smaller width road to the larger width road, which might be harder to do with an extruded CSG mesh.

That said, I don’t have a lot of experience with using CSG nodes in Godot, so there might be a way to achieve what you are looking for with a single path 3D node.

Hopefully this helps!

Hi.

Unless your plan is to create CSG nodes at runtime (which essentially means procedural generation), it's always more flexible and powerful to create your levels in a 3D program like Blender and export to Godot using the Better Collada addon.

It would make everything run faster too, as it's not exactly cheap for Godot to calculate realtime boolean operations for large trees.

I just realized that I didn't thank you for your advices ! Sorry for that ! It was really helpful :) thanks !
