[RELEASED] Curvy 2 - the ultimate spline solution

I am working on trying to use Chronos and Curvy right now. The Spline Controller does some unique things with time instead of using delta time and calculating its own delta times. I am "working on" getting them to work together for my own limited uses cases. Was curious if you ever got them to work? Thanks!

 

Was that you who asked in our support forum as well? I replied there

 

CurvyController uses Time.deltaTime when playing (by utilizing DTTime.deltaTime which returns a working delta in the editor as well). I don't know Chronos, but how does it work to manipulate the actual time (and as a follow up question, what does it need to be compatible)?

 

I just started using it. I was able, without much work to get the CurvyController to use chronos time. Though I only made it work for the branch of code I happen to be using, skipping a lot of the "inEditor" stuff. I still have a "scale" problem where the object moves faster along the spline then before but that's easy enough to fudge for now. The SplineController uses time to handle passing between splines.

Here is the chronos migration guide.

Yeah, you'll need to make CurvyController use Timeline.deltaTime instead of Time.deltaTime. If you examine the source, you'll find the usage of DTTime.deltaTime. Either replace that or change the property in the DTTime class (inside DTUtility.cs).I recommend the latter because DTTime won't be updated as much as CurvyController.cs will.

 

Pre-purchase question: Just checking that Win Universal support isn't planned to be released in the next few days. I would really love to use this for a course project but I have an aggressive timeline.

 

Core Curvy (i.e. splines and controllers) is already working with WinUniversal, but Curvy Generator is giving me hard times. Also I'm struggling with some weird errors with texture resources from the editor that forces one to restart Unity after each successful compile. But it's definitely on the way...

 

Ok, good to know, thanks! Curvy Generator is a feature we wanted to use so we'll probably go with an alternative, but best of luck getting it to work.

 

Hey Jake,

Quick question, we are trying to create a standalone build for windows x64 but we are having some weird issues with the build that I believe are due to something happening during the build process. After the standalone player builds I get approx. 8 of the following errors :

NullReferenceException: Object reference not set to an instance of an object
FluffyUnderware.Curvy.CurvyConnection.OnDestroy () (at Assets/Packages/Curvy/Base/CurvyConnection.cs:101)
UnityEditor.HostView:OnGUI()

The problems with the build have nothing to do with Curvy (In the built version of the game I get null references where there are none in the editor (clearly there are references in the inspector) and if I rebuild without changing anything I don't get the same error but I will get a different one in another scene that was previously fine....) but the errors are the only thing I can see from the editor console.

Cheers,
Colton

 

That's in fact weird, I will run some tests to see if I can reproduce it. Btw, what Unity version you're using?

 

Unity version 5.3.3p1. I also noticed that I get 8 of these errors and I have 8 scenes that have splines in them.

EDIT : Still getting the errors in the console after building.. I was able to solve the issue with the built version though. Looks like I had some kind of race condition or something because my GetComponent<T>() wasn't working but manually assigning the reference worked fine.

 

Hi Jake,

Do we have solutions to render a RANDOM piece of a spline? Say, how can render position [30, 100] with a colour and [130, 230] with another colour? Thank you.

 

You can limit the range of an extrusion in the ExtrudeVolume module (or alternatively in the InputSplinePath module). To extrude multiple pieces, use multiple Extrude modules. You can, but not need to, combine them into a single CreateMesh module then.

 

I'd like to point all Curvy users familiar with major 3D packages (or working in a team with 3D programmers/artists) to this post. Thanks!

 

Its very disappointing that Curvy 2 does not work on the Windows Store platform. I am currently stuck with 56 Errors that I cannot fix, all related to System.Reflection GetType

As it stands I cannot port my newest game to the Windows Store, and I cannot port my old games to Curvy 2 because it does not work in Windows Store.

Please fix this, you don't even have to make it all work, (I don't need to make splines in Windows), the spline just has to run. Hide any editor code behind ifdefs. That should cut down the workload.

 

Curvy 2.1 adds Windows Store compatible (UWP 8.1/10). It's already submitted for review and will arrive shortly in an AssetStore next to you!

 

Is there a way to add a new control point in the middle of an existing curve?

 

Sure. Just use CurvySpline.InsertAfter() with the previous CP in question as parameter. You could use CurvySplineSegment.Interpolate() from the same CP to get the position for the new CP.

 

@Jake L.

Thanks, Got it.
This should be part of the Curvy UI though.

 

It is.

 

That's right: Either select a range of CP's and use the Subdivide command from the "CP Tools" toolbar button or select a CP and CTRL-Click anywhere while in Spline Draw Mode (Hotkey "Space") to insert Control Points.

Hi,
I'm researching possibilities to use Curvy for my project:
http://steamcommunity.com/sharedfiles/filedetails/?id=604035651

I would like to use it for runtime generation. That's is possible as I read.
I'm curious if these use cases are supported in content generator too:
Adjust terrain heightmap by generator?
Generate river/stream mesh based on spline. Simply I want to generate "nearly" horizontal mesh based on spline and use water shader for it. Maybe shape mesh based on intersections with terrain?

Thanks
Peter

 

Hi Peter,

comfort to ground is currently only supported for paths, not extruded volumes. The latter as well as terrain shaping and dynamic shape side extensions are planned features, but I can't give a timeframe for that.

Jake

 

Does anyone know how I could export a Spline from Blender so that Curvy can import it? Blender doesn't really have a dedicated JSON serializer.

 

For what it's worth: I remember wanting to do just this a couple of years ago, and I did manage.. It was something something handheld with empty's in Blender, exported as FBX, listing alphanumeric in unity, pasting Spline data onto them.. something something.. it worked

 

There is a experimental blender exporter in work, but it's not fully polished yet...

 

Don't forget to visit the AssetStore - it's Madness Sale time!

 

I am getting this error after importing Curvy: Assets/Packages/Curvy/Base/CG Modules/Editor/NoteEditor.cs(16,31): error CS0309: The type `Note' must be convertible to `FluffyUnderware.Curvy.Generator.CGModule' in order to use it as parameter `T' in the generic type or method `FluffyUnderware.CurvyEditor.Generator.CGModuleEditor<T>'

Anyone have idea what is going on?

 

I'd guess one of the involved classes is already present in the project ('Note' or 'NoteEditor' most likely). Either that or the package wasn't imported completely. I just imported Curvy into a fresh project (Unity 5.4) and it compiles fine.

By the way, the 'OnLevelWasLoaded' warning introduced with Unity 5.4 can be ignored, but it will be fixed soon!

 

Hello, i just bought curvy in the MADNESS sale, and i get a few errors after importing it into my project:

https://gyazo.com/6a7cadbd75bb5456051fb1d330b26d5c


Thoughts?

 

The errors looks like not everything was imported, so please reimport the package. Perhaps delete the Curvy, CurvyExamples and DevTools folders under /Packages before importing again - just in case.

 

Well, i tried redownloading and doing that though it didn't fix it. Its worth noting that i don't have unity pro. I noticed there seems to be a lot of pro only shaders that curvy includes.

 

I'm sure we'll get this sorted. Curvy doesn't use any Pro-Only features, so it must be something else.

 

Hi there,

i don't know if this is the right Asset for me, so here is the question. I want to build in the feature that the player has the possibility to build power poles, train tracks or pipelines in the game (like SimCity). Would Curvy 2 make it possible to build this within the game (at runtime)?

Hope you know what I mean.

Thanks a lot!

 

I have a bezier spline with a spline controller. I need to know when the controller has reached the end of the spline, I tried using .position but it reaches 1.0 on the first control point on the spline not at the end of the entire spline.
So my question is how do I get a value of 0 to 1 for the entire spline not just the spline segments?

 

If you watch the trailer, there's a scene showing track editing in the railroad scene. The same can be achieved at runtime, but you'll need to add Control Point interaction by yourself (i.e. grabbing and dragging of CP's, everything that is done in SceneView in the editor). Allthough, it will be some work to make it feel & behave like road drawing in SimCity. So it's possible, but there is no "Draw Tracks" easy mode included.

@arkon

"Position" depends on the movement mode ("Relative" or "Absolute"). You might want to use "RelativePosition" that goes from 0..1 or bind the OnEndReached event.

 

I wonder why in the asset store description there is no link to this forum or to custom support on the official website, it would even more trust about the very good and helpful support

I have already bought other spline assets, but when I found this one, this is the best one I have seen that gives lots of different features, is easy to use and gives very good results.

It can be used for many different things and is much more than just splines.

It also includes 22 example scenes to show all the possible things it can be done, so you can see for yourself how it is done and you can learn faster and see how it works

love it!!

 

Hi, just started using this asset. I'd like to ease the movement along a spline, so I'm using the Animate curve as previously suggested. However, when using this it seems that the OnControlPointReached event no longer works. It would be nice to have more robust easing features! Am I just missing something in regards to Animate?

 

How do you disable the scene ui menu? I can disable it the menu in preferences, but the import/export but hangs around?

 

It'll be fixed with the next release next week, until that we provide a manual fix for this bug.

@qkjosh:
I'll look into this issue and provide a fix next week (currently on vacation).

@SpaceRay:
We had links to the forum some time ago but dropped it in favor of a direct link to Curvy's website where forum and other resources are linked. But you're right, adding it again might be a good idea.

 

Hello Jake,

I am using your awesome, excellent and well done Curvy with an flying helicopter and some weapons, and they look very good. Surely for me your spline manager is the best one available.

The problem is that you are using a PoolManager.cs script, and I with the weapons comes another PoolManager.cs script and as you know well, you can not have two scripts with the same namespace in the same project.

I modified the scripts of the Curvy asset renaming the PoolManager name to PoolManagerCU on the filename and all through the scripts content, but the problem is that there is one script that does not allow to change the names as they keep being red when modifying, so this script still is giving errors and I can not hit play as I can not remove the errors

SUGGESTION OF NEW NAMESPACE

The real reason of this post is to suggest that you could change the Poolmanager namespace to another one like for example PoolManagerCU or PoolManagerCurvy, so this way you avoid any possible conflict and problems with any other possible asset that may also have a Poolmanager script, and so there would not be any problem using your own awesome asset combined with any other asset with pleasure and without any problem.

 

Hi SpaceRay,

the PoolManager Curvy uses is already namespaced (FluffyUnderware.DevTools), so either your other Poolmanager isn't namespaced or you're using both in the same script. In that case you should set an alias for at least one of them, e.g.

Code (CSharp):

1. using PoolManagerCU = DevTools.PoolManager;

Renaming the script isn't recommended, you'll get in trouble on next update.

 

This might've been asked before but it seems you've done lots of updates. Does curvy support some kind of procedural object placement, spline adjustment etc at runtime, i.e. can you generate an entirely procedural tunnel/tube/roads and have objects placed on them randomly etc? Or does everything have to be build in the editor?

 

+1 for all above questions. However, the developer stated multiple times that all editor operations exist in the API and can be used in runtime but a workable scene demo with all these capabilities would be awesome. This asset is great

 

You can do all of these things. You can access and alter the nodes of the spline and refresh it. You can access any one point on the spline. The API is easy to use. Check out the documentation here:

http://www.fluffyunderware.com/curvy/documentation/splines/start

 

Yes to all questions except the last: There's not much difference between editor and runtime. Also, there's an example scene that creates both spline and Generator (procedural content) dynamically by script from scratch.

 

Ok sounds good. Although what I presume is, if I want to proceduralize I need to go into scripting, ie there isn't any settings or user interface at editor-time, in the in editor, that would let me set up and configure 'what' would be randomized at runtime or how? ie can I make it procedural without coding?

 

Great asset!

I have a (hopefully) dumb question, easy to answer: How do I create - using the API at runtime - a smooth, semicircular arc with a bezier spline consisting of a start point, an end point, and a mid point? All three are at the correct coordinates to draw a 3-point circle, I just need a hint on how I'd set the handles of the mid point so that the spline interpolation is a semicircular arc between the start and end points.

Does this make sense?

Thanks!

 

You can work with Curvy Generator at editor time and modules that rely on randomness (object placing etc.) will generate different results on each run (toggleable option). But of course you'll have much more options with a bit of scripting.
