Thats the script. You can see the variables in how it adds the Vector2.
EDIT: also, I think the file I posted has the comments removed, but you need to remove the comments before using
EasyRoads3Dv3;
using EasyRoads3Dv3Editor;
I removed them in the script above.
EDIT2: Ok with the help of Shimonko, he helped me understand the script.
So with the script above the following is the graphic Shimonko gave me to help understand the road.
And here is a sketchup I did to show how the variables are linked, its not pretty but helps me understand it.
And then even with that great explanation and thinking I understood it, I still managed to mess it up but Shimonko was patient and helped me with it.
Here is the modified code that will work for cart paths that are 3 wide like mine.
using UnityEngine;
using UnityEditor;
using System.Collections;
using System.Collections.Generic;
using EasyRoads3Dv3;
using EasyRoads3Dv3Editor;
public class ERAPIEditor : ScriptableObject {
[MenuItem( "EasyRoads3D/Custom Road Shape" )]
public static void RefreshRoad()
{
ERRoad road = EREditor.GetSelectedRoad();
if(road != null){
List<Vector2> shape = new List<Vector2>();
List<float> uv = new List<float>();
List<bool> tris = new List<bool>();
shape.Add(new Vector2(1.5f,0f));
uv.Add(1f);
tris.Add(true);
shape.Add(new Vector2(1.4f,0.1f));
uv.Add(0.99f);
tris.Add(true);
shape.Add(new Vector2(0f,0.1f));
uv.Add(0.5f);
tris.Add(true);
shape.Add(new Vector2(-1.4f,0.1f));
uv.Add(0.01f);
tris.Add(true);
shape.Add(new Vector2(-1.5f,0f));
uv.Add(0f);
tris.Add(true);
road.roadScript.roadShape = new List<Vector2>(shape);
road.roadScript.roadShapeUVs = new List<float>(uv);
road.roadScript.doConnectionTri = new List<bool>(tris);
road.roadScript.isCustomRoad = true;
foreach(ERMarkerExt m in road.roadScript.markersExt){
m.roadShape = new List<Vector2>(shape);
}
road.Refresh();
}else{
Debug.Log("Please select a road object first");
}
Debug.Log("done");
}
}
I personally like the thicker road look and it should provide more forgiveness from floating roads that can happen with EasyRoads.

A great view of what this script actually does (you will notice shimonko's drawing mimics this).
NOTE: I think it causes trouble with pefab connnections, so depending on how you do your connections (I don't use connectors yet).
Matt, I think this will work with free version of v3.0. I don't see why it wouldn't. Let me know if you have any questions. Please note I am still a rookie with unity, CF, and easyroads.
The course I am working on is South Hills in West Covina.
