[RELEASED] Curvy 2 - the ultimate spline solution

@up I had got the same problem some time ago.
You will probably not be able to do it the easy way. (if you manage please tell me how you did this)
I had to change some of the curvy components to take data from outside, so I can reuse/share it in multiple places. (ex: multiplier curve)

 

Hi

From the screenshot, I can see that you are not using the latest Curvy version. As you can see in the screenshot bellow, I have the desired result with the latest version



I attached the scene file if needed

I tried what you said it works for the most part


except here, where there seems to be a strange rotation


using the same setup as in the scene you sent

 

Probably because of a big change in the orientation at that point. Can you try, as an experience, to set the path resolution in the Shape Extrusion module to the maximum, while disabling Optimize?

 

That helped, thanks! I also tweaked the cross base value which helped as well.

 

Humm, also, for spline controller to be relative, if I have Rectangle, I want 0.25 meaning 1/4 position along the total path distance, not each corner. I think this is a bug ? For relative mode the position has to be along the total distance of the path, not the control point?

 

Hi
For spilne controllers, relative mode is equivalent to TF. Explanation here: https://curvyeditor.com/documentation/controllers/start#position

 

Ok, fair enough, but I think there should be an option to use TF for relative mode or absolute mode like 0-1. Sure, we can just use absolute mode and do the division ourselves, but... that's another user step that we have to "calculate" if we want the object to start follow at say exactly 1/4 of the total distance... Give us option so that relative mode uses distance range from 0 - 1.

 

I agree with you. I am aiming at implementing this in a future update.

Hi! I'm searching for a spline asset which I could use to make 3D "islands" with premade tile border assets (just like your road with lights example), but for this I would need a Cap function to make the top part of this model.

Imagine a circle made with Curvy. The edges would be the model (like the road, but to serve as the edge of the island) and the top would be a simple plane which I could assign a tiling material to match with the border's material.

Would this be possible with Curvy? This is what I'm trying to achieve, but in 3D with splines:

 

Hi

If I understand you well, and this picture resembles to what you try to achieve, then yes you can do it via Curvy Splines



I attached the scene that I created to produce the above screenshot

Let me know if you have other question
Have a nice day

 

I noticed the Extrude function, but it's not quite what I'm looking for. I'd like to add a custom mech for the border and fill the center with a ngon mesh cap with a tiled material...

The edges of the extrusion are quite sharp and straight, I'd like to make a custom mesh to simulate the rocks and use that as a base

 

Then, if I understand you correctly, you can place the rocks on the borders using the Curvy Generator. In this tutorial you can get an idea about how to do it:

I will list bellow other features that might be helpful to make your island:

• The shape extrusion can use a variable shape through the extrusion using the Variable Mix Shapes module: https://curvyeditor.com/documentation/generator/modules/variablemix
  You can see it being used in the WebGL demo: https://curvyeditor.com/demo
  
• You can make a flat mesh from any spline using the Spline To Mesh tool: https://curvyeditor.com/documentation/toolbar/start?redirect=1#tools
• You can apply a scaling while extruding a shape: https://curvyeditor.com/documentation/generator/modules/shapeextrusion#scale

Did this help?
Have a nice day

 

Yes, this was very helpful. Thanks!

Just one more question, though... Would I be able to mark the generated mesh as static and bake lightmap information as any other meshes in scene?

 

Yes, all possible

 

I bought this plugin year back. I started working with it from few weeks back. In editor its working fine. But building on windows x86_64 I am getting there following null reference exception.

Hi
You are having a NullReferenceException inside a Unity method (Transform.get_localPosition) which is never supposed to happen. What I suggest:
First, try to reproduce the issue in a new minimal project. Then open a Unity bug ticket, using Unity's bug reporting tool, while attaching that project. While waiting for their answer, try using another (older and newer) version of Unity, it might not have the issue. You can also send me that minimal reproduction case, I am not sure I can be of any help, but I will give it a try.

 

Indeed.
What exact version of Unity are you on @Aldo-V ?

 

I found the cause seams like on runtime I cant simply Destroy CurvySplineSegment gameobject like I been doing in Unity editor play mode.

 

I am try to add CurvySplineSegment gameobject to spline instead of CurvySpline.Add(Vector3).

Code (CSharp):

1.  
2.                 curvySpline.enabled = false;
3.                 var curvySplineSegment = node.GetComponent<CurvySplineSegment>();
4.                 curvySplineSegment.LinkToSpline(curvySpline);
5.                 curvySpline.enabled = true;
6.                 curvySpline.Refresh();

I got it working only by component disable and enable. Its not updating with just Refresh. Is this right way of doing?

 

Hello,

I have created a small road network connected to each other using Curvy and I was wondering if I can somehow be able to get a shortest route/path information from current vehicle position to point B (located somewhere, where player desire to go)...

Maybe someone solved this earlier?

 

How to generate UV2 for lighmapping when doing the extrusion and using VolumeMesh ? (or other method)

 

Hi

You should use the Add methods or the Insert methods to add control points. They do more than just adding the object to the hierarchy (handling events for example). So modify your code to avoid using the GetComponent<CurvySplineSegment>, enabling and disabling, and see if the issue is gone.

The game object destruction methods that you have to use in edit mode and play mode are different. You will learn more about this by reading the Unity documentation of Destroy and DestroyImmediate

 

In the Create Mesh module, you have an Add UV2 option
https://curvyeditor.com/documentation/generator/modules/createmesh?s[]=uv2#add_uv2

 

Curvy Splines does not include any path finder. Using the Curvy's API, you can get all the needed data about your network to input to any path finder. If you are new to this field, this page is a good start: https://en.wikipedia.org/wiki/Pathfinding

 

Unfortunately this method created very stretched UV's
I had to extend Create mesh and after creating mesh I run unity's
Unwrapping.GenerateSecondaryUVSet

 

There is indeed an issue with UV2 generation under some circumstances. Please send me privately your invoice number, and I will send you the patch to fix that.

 

I didn't meant difference between editor edit mode and play mode. I meant difference between editor playmode and runtime on target build. I just provided information for you that its not Unity bug as you said earlier.

 

Noted. So did you try the solution I suggested? Did it work?

 

I had specific use case where I wanted to add waypoint prefab to spline. Waypoint prefab is bit complex with few scripts and meshRenderer so Inserting points using Add/Insert and adding back required components is again lots of AddComponent code. Anyway other than this use case Add/Insert works perfect. I realize I could also add waypoint prefab as child of waypoint if I encounter any performance issue, so no problem thank you for support.

 

You are welcome. If I can be of further help please let me know. Also don't hesitate if you have any improvement suggestion.
If and when you feel like it, please leave a review for the asset, that helps a lot.
Have a nice day

 

hi, CurvySpline.Count api returning incorrect segment count. for 2 segment returning 1 and for 1 segment returning 0. Any idea?

 

Seams like CurvySpline.count returning returning 1 less segment count for CurvySpline.Closed = false but correct no. of segment for CurvySpline.Closed = true

 

Hi
Count = number of segments
ControlPointCount = number of control points
If your open spline has two control points one at it start and one at its end, then there is only one segment (one line) between those two points.

 

I'm trying to generate a mesh along a linear spline.


However, I"m getting artifacts like above. My Shape extrusion node is as below.


Is there any way to avoid this?

 

Hi
There is a forum thread about this issue. I posted an answer there: https://forum.curvyeditor.com/thread-1135-post-4068.html#pid4068
Let me know if you need more information.
Have a nice day

 

Hi everyone,
Curvy 7.1.5 is live. Release notes available here https://curvyeditor.com/releasenotes.
Have a nice day

 

Hi,
How to get next frame's position and rotation in advance from existing spline controller? These values come in handy for moving platform implementation.

 

Hi
First, store your controller's Position. Then make you controller advance by one frame by calling yourController.ApplyDeltaTime(yourFrameDuration)
Then use whatever data you need, and then finally reassign the Position that you have stored in the beginning.
This method is good as long as you don't care about the events and connections being handled by your controller when you call ApplyDeltaTime.
Did that work out?

 

Yes it worked out. Thank you so much.

 

You are welcome. If and when you feel like it, please leave a review for the asset, that helps a lot.

 

Hello @Aka_ToolBuddy, I'm having problems with a generator and keep getting the same error:



[Curvy] Getting data from a dirty module. This shouldn't happen at all. Please raise a bug report. Source module is Rasterize Path (FluffyUnderware.Curvy.Generator.Modules.BuildRasterizedPath)

The generator is part of a prefab. I'm not sure what the intended workflow for prefabs is, though, but I want to reuse this generator in different scenes with different source paths and slightly adjusted values.

When I open the prefab to edit it, after a short while of working all connections disappear and I can only fix it again by reverting the prefab to a previous version.
When I edit the generator on the prefab in the scene, I get the above error all the time. It feels like prefabs aren't supported, but I really need a way to keep making adjustments without having to do all scenes over and over.

Can you help me?

 

Oh, and another (unrelated) thing. Is it possible to ignore bounds for spacing when creating a spots volume?
I couldn't find a way yet and without bounds, it doesn't work. I'd like objects to spawn let's say every 5 units, no matter their size.

 

Hi Orion

Since the (not so) new prefab system, Unity forbids some modifications on prefab instances, such as deleting an object that is part of a prefab instance. To do such modification, you will have either to unpack the prefab instance (ie: remove its link with the prefab asset), or you will have to delete the object inside the prefab asset.

When it comes to Curvy, Curvy Generators do create and delete objects, such as the mesh resulting from a shape extrusion. When a generator is part of a prefab instance, such deletions are in conflict with the restrictions made by the new prefab system. When Curvy detects such conflict, it shows a console error. Did you get such error?

• If yes, please modify your prefab asset to remove all the generated meshes and game objects from it. You can recognize them as the children of your Create Mesh and Create GameObject modules.
• If no, then your issue might be different, in which case can you tell me what error messages you do have, and can you send a reproduction case?

Curvy 8 will fix this issue

 

For this one I need a reproduction case.

 

The Volume Spots has a Space Before and Space After parameters, which I believe will answer your need: https://curvyeditor.com/documentation/generator/modules/volumespots#space_before

 

Ah, great. It looked like it was offset by the bounds, but I was mistaken. My bad.

Yeah, the problem is not the objects being created/deleted. I had that sorted out. The problem is that if I open the prefab, and add new nodes, things break, and if I don't open it and add new nodes, things also break (but differently).

 

Ok, so this is an issue new to me. Is it possible to have a reproduction case?
