Road Architect: Roads, intersections and bridges for Unity [RELEASED]

thanks for the report, @jdm4344, i will post an update. i will also include that change in the updated .unitypackage when it is ready.

 

Hello guys..not sure anyone is still active here but I will give it a try..Im using Unity 2018 and road architect works just fine..the only thing I like to know is how to use the tunnels..If I used like making a bridge or just apply between 2 notes it will cut mine mountain in two..any suggestion??

 

I've done something similar. You'll need to use an asset that can create a hole in your terrain, I cant remember the exact one I've used, but you'll need something like this: https://assetstore.unity.com/packages/tools/terrain/microsplat-terrain-holes-97495

Good Luck

 

@dsm350 Create your mountain in a modelling package like Blender (free). Now you can put holes in it where ever your heart desires. Alternatively, just model the top half of the mountain and place it onto the terrain on top of your tunnel.

Hello,
I am having a problem with creating a new road.
I create a terrain and then create the road network and then I click add road.
When I click ctrl + click instead of placing a marker the terrain is selected.
Am I missing something?
Thanks,
Tom

 

I have resolved this problem. It was a problem with my custom layout. I just used unity's already existing layout. I don't know the cause but it is not related to Road Architect.
Sorry for the inconvenience

 

Thanks Texmax and Mark..I have another question. how to connect one road to each other..like a circle for race track?

 

Has anyone managed to create highway ramps connections using road architect? I really love how intuitive this asset is, and it's so sad it's not supported anymore. The only thing missing for me to use it in our project is to have ramps

 

Anyone is having the problem where the terrain is affected by Road Architect but doesn't revert the terrain to its original state when moving nodes?

 

Newbie question here, I put the RoadArchitect-Master folder into my assets folder and Unity seems to have imported it, but the Road Architect option doesn't appear in the menu, even if I shut down and restart Unity. Is there anything basic I've overlooked?

 

@Hypester It needs to be called just RoadArchitect and not RoadArchitect-master.

Also, what Unity version are you using?

 

Ramps are not supported in my fork (not sure about FritzsHero's fork, https://github.com/FritzsHero/RoadArchitect).

That is a general problem with RoadArchitect. It forgets about terrain state under certain conditions. Probably won't be fixed in the short term unless interest develops.

 

Hello, i am trying to insert group objects dynamically (namely, GSDGroup-KRailLights-6L and GSDGroup-Fancy1-6L) to a continuous road generated in runtime, and cannot find a clear way to do this through code. I have browsed the road automation script and tried loading these objects directly upon programmatic node creation with:

tNode.LoadWizardObjectsFromLibrary("W/GSDGroup-Fancy1-6L", false, false);

on the method:

public static GSDSplineN CreateNode_Programmatically(GSDRoad tRoad, Vector3 NodeLocation)

It seems far too simplistic and sure enough it fails. Could you shed some light on this, please?

 

First of all, I'm curious how you were able to do that! I didn't know it was possible to create a road at runtime when not running inside the Unity editor, as the road creation APIs are not available in a built game.

Try loading them once you have three nodes. Loading those objects on a single node won't work very well.

 

Thanks for the response. I've really dived in and the whole project is amazingly complex. For this idea I've just followed along the lines of the GSDRoadAutomation.cs and the GSDUnitTests.cs. The key point was finding out that it had to run on single thread (by default RoadArchitect runs multithreaded). Here's the quick example to check if it's working:

Code (CSharp):

1. public class InsertRoad : MonoBehaviour
2. {
3.     private GSDRoadSystem roadSystem;
4.     private GSDRoad road;
5.  
6.     void Start()
7.     {
8.         CreateNewRoadSystem();
9.  
10.         List<Vector3> nodeList = new List<Vector3>();
11.         Vector3 v1 = new Vector3(500, 0, 0);
12.         nodeList.Add(v1);
13.         Vector3 v2 = new Vector3(500, 0, 1000);
14.         nodeList.Add(v2);
15.  
16.         InsertNewRoadSegment(nodeList);
17.     }
18.  
19.     private void InsertNewRoadSegment(List<Vector3> nodeList)
20.     {
21.         roadSystem.opt_bAllowRoadUpdates = false;
22.         foreach (Vector3 node in nodeList)
23.         {
24.             GSDSplineN f = GSDRoadAutomation.CreateNode_Programmatically(road, node);
25.         }
26.         roadSystem.opt_bAllowRoadUpdates = true;
27.         roadSystem.UpdateAllRoads();
28.     }
29.  
30.     private void CreateNewRoadSystem()
31.     {
32.         GameObject tRoadSystemObj = new GameObject("RoadArchitectSystem");
33.         roadSystem = tRoadSystemObj.AddComponent<GSDRoadSystem>();
34.         roadSystem.opt_bAllowRoadUpdates = false;
35.         roadSystem.opt_bMultithreading = false; // This is key for runtime generation
36.  
37.         List<Vector3> empty = new List<Vector3>() { };
38.         road = GSDRoadAutomation.CreateRoad_Programmatically(roadSystem, ref empty);
39.  
40.         road.opt_bIsLightmapped = true;
41.         road.opt_bIsStatic = true;
42.         road.opt_Lanes = 6;
43.         road.opt_ClearDetailsDistance = 36;
44.         road.RoadMaterial2 = GSD.Roads.GSDRoadUtilityEditor.GiveMaterial(GSD.Roads.GSDRoadUtilityEditor.GetBasePath() + "/Materials/GSDShoulder1.mat");
45.  
46.         roadSystem.opt_bAllowRoadUpdates = true;
47.         roadSystem.UpdateAllRoads();
48.     }
49. }

The highway group object is really awesome and it's worth the hassle. I will test again, as i think you are correct, i'm trying to load the group object right off from the first node generated:

Code (CSharp):

1. public static GSDSplineN CreateNode_Programmatically(GSDRoad tRoad, Vector3 NodeLocation)
2.         {
3.             int SplineChildCount = tRoad.GSDSpline.transform.childCount;
4.             GameObject tNodeObj = new GameObject("Node" + (SplineChildCount + 1).ToString());
5.             GSDSplineN tNode = tNodeObj.AddComponent<GSDSplineN>(); //Add the node component.
6.          
7.             if (NodeLocation.y < 0.03f)
8.             {
9.                 NodeLocation.y = 0.03f;
10.             }
11.             tNodeObj.transform.position = NodeLocation;
12.  
13.             tNodeObj.transform.parent = tRoad.GSDSplineObj.transform;
14.  
15.             tNode.idOnSpline = (SplineChildCount + 1);
16.             tNode.GSDSpline = tRoad.GSDSpline;
17.  
18.             //tNode.LoadWizardObjectsFromLibrary("W/GSDGroup-Fancy1-6L", false, false);
19.             tNode.LoadWizardObjectsFromLibrary("W/GSDGroup-KRailLights-6L", false, false);
20.             //tNode.LoadWizardObjectsFromLibrary("W/GSDGroup-Rumblestrips-6L", false, false);
21.             //tNode.LoadWizardObjectsFromLibrary("W/GSDGroup-WBeamLeftTurn-6L", false, false);
22.  
23.             tRoad.UpdateRoad();
24.  
25.             return tNode;
26.         }

 

One suggestion: before you dive in too far, I suggest that, if you aren't already, use my fork instead of the official repository (link below). My fork has several bugfixes applied by me and FritzsHero.

 

Yes, thanks. I did went for your fork after this. And after dozens of prints everywhere... I think I found a solution! In fact, programmatically only after a call for

GSDRoadSystem.UpdateAllRoads()

is the road actually created along with its base objects. Until then we've just set the nodes. In Unity editor this is automatic but not when done in code. So, to insert other custom objects there should be a second iteration over the nodes, after the road has been created. For anyone who wants to test it, don't lose sight of the GSDRoadAutomation.cs and setup a empty game object with some variation on this script. Note: This means it's possible to create and customize a road/bridge/etc with all of RoadArchitect objects just in code and on runtime, either adding segment after segment with some kind of trigger (which i found to be rather too expensive in terms of framerate) or at runtime start receiving distance parameters and random node positions for example.

Code (CSharp):

1. using GSD.Roads;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class InsertRoad : MonoBehaviour
6. {
7.     private GSDRoadSystem roadSystem;
8.     private GSDRoad road;
9.  
10.     void Start()
11.     {
12.         List<Vector3> nodeList = new List<Vector3>();
13.  
14.         Vector3 v1 = new Vector3(0, 0, 0);
15.         nodeList.Add(v1);
16.         Vector3 v2 = new Vector3(0, 0, 1000);
17.         nodeList.Add(v2);
18.  
19.         CreateNewRoadSystem(nodeList);
20.     }
21.  
22.     private void CreateNewRoadSystem(List<Vector3> nodeList)
23.     {
24.         GameObject tRoadSystemObj = new GameObject("RoadArchitectSystem");
25.         roadSystem = tRoadSystemObj.AddComponent<GSDRoadSystem>();
26.         roadSystem.opt_bAllowRoadUpdates = false;
27.         roadSystem.opt_bMultithreading = false; // This is key for runtime generation
28.  
29.         road = GSDRoadAutomation.CreateRoad_Programmatically(roadSystem, ref nodeList);
30.  
31.         for (int i = 0; i < road.GSDSpline.mNodes.Count - 1; i++)
32.         {
33.             road.GSDSpline.mNodes[i].LoadWizardObjectsFromLibrary("GSDGroup-KRailLights-6L", true, false);
34.             road.GSDSpline.mNodes[i].LoadWizardObjectsFromLibrary("GSDGroup-Fancy1-6L", true, false);
35.         }
36.  
37.         road.opt_bIsLightmapped = true; // These are just a quick way to edit the road
38.         road.opt_bIsStatic = true;
39.         road.opt_Lanes = 6;
40.         road.opt_ClearDetailsDistance = 36;
41.  
42.         roadSystem.opt_bAllowRoadUpdates = true;
43.         roadSystem.UpdateAllRoads();
44.     }
45. }

 

I hope you are not planning to build this into a standalone Unity game. As far as I know, the road creation code can only be used by scripts when they are running in the editor.

 

Thanks for the heads-up @embeddedt. I've made a few tries on building a standalone and it actually looks feasible, although it involves disabling or replacing all of the UnityEditor API calls and loading resources carefully (as of right now a test version manages to generate road with some objects but not every material/texture is being loaded properly). From what I read,

Resources.Load<T>

should work on a windows build, replacing

UnityEditor.AssetDatabase.LoadAssetAtPath

(...and it's loading fine in Unity). I'll keep trying.

 

Let me know if you need any assistance. I'd be interested in these changes if you are willing to contribute them.

 

shadows are not displaying on the road

 

A few people mentioned they were having a hard time getting Road Architect setup in Unity, here's a getting started tutorial.

 

Hi guys,

I m a beginner. Great asset first of all.

I m trying to build a road over mountainous areas but anytime I build the road it automatically flattens the area. Is it possible to get the road to match the bumpy terrain?

I m using Unity 2018

Thanks,

Conor

 

The road flickers with standard lighting + post processing, any help please?

 

You can try https://github.com/FritzsHero/RoadArchitect or https://github.com/embeddedt/RoadArchitect - these forks are a bit more compatible with modern versions of Unity.

 

Thanks. It seems FritzsHero is more recent (although both are from 2019). Which one would you recommend? Is the road flickering a known problem of the "old" architect?

 

FritzsHero's is actually a fork of mine, so I would suggest you use the former, as it's been updated more recently.

The old version has a number of known issues, several of which I was successfully able to patch.

 

Thanks! The FritzsHero repo solved the issue with flickering.

 

Hello, using your fork and compiling I'm seeing this error:
Assets\RoadArchitect\GSDRootUtil.cs(414,23): error CS1061: 'GSDRoad' does not contain a definition for 'bProfiling' and no accessible extension method 'bProfiling' accepting a first argument of type 'GSDRoad' could be found (are you missing a using directive or an assembly reference?)

 

Try https://github.com/FritzsHero/RoadArchitect it's much more up-to-date (I haven't updated mine in almost a year).

 

https://github.com/FritzsHero/RoadArchitect

(Better clickable link.)

 

I having a Unity build error, how can i fix this "bprofiling"?

Code (CSharp):

1. Assets\RoadArchitect\GSDRootUtil.cs(395,23): error CS1061: 'GSDRoad' does not contain a definition for 'bProfiling' and no accessible extension method 'bProfiling' accepting a first argument of type 'GSDRoad' could be found (are you missing a using directive or an assembly reference?)

 

Problem solved. Appreciate the help!

 

hello so i have an issue where when intersect the road on both ends with another road it just disappears does anyone have a similar issue help would be appreciated

 

OK. I have downloaded this twice now different forks but non is working. No bridge or side objects in the wizard. When trying to place roads pink shows. I'm using unity 2019.3.
Please help

 

What version of unity are you using please?

 

Is there a way to make a road segment one-way programmatically?

 

Just curious to know if RAMPS are support now or Y intersections ? Great tool though !

 

Does this come with LOD?

 

Is it possible to create an underpass with this asset?

 

Are you able to do closed circuits yet? I placed 48 nodes around a racetrack and now I'm facepalming a bit.

 

Hi MicroGSD,
You all were doing great things but now in 2022 it all seems to have been dead. The features promised never arrived and we are still waiting humbly about when will the next feature arrive.

 

Hiya, I am unable to create a closed loop circuit. Is there a way to do this?

 

Are you using the github version?
