Official SpriteShape Preview Package

Hi,
after upgrading to Unity 2019.1.1 and even after upgrading SpriteShape to the latest version, it seems to cause huge FPS drops whenever a SpriteShape object is in the scene.

Is this a known issue? Do we need an extra step to upgrade SpriteShape properly?

Thanks for any advice

 

This is what it looks like in the profiler:

 

I apologize if I'm missing something simple-- The 2D SpriteShape package does not appear in package manager for 2019.2.0b (https://i.imgur.com/xMfeYHk.png). I have not yet installed the package.


Thank you!

Edit: Solved. My apologies-- Forgot to enable preview packages in the settings.

 

Hello, I would like to ask - is there any way how to achieve scrolling of the closed sprite shape?
Something like for renderer: renderer.material.mainTextureOffset = offset.
I would like to achieve scrolling of force field (arrows) in 2D top view game.

 

Hi, I've updated Unity to 2019.1.3f1 and noticed the bevel options are no longer availabe. Is this intended?

 

Another question if I may, is it possible to create shapes with "holes" in them? Something similar to the following, withouth the "connecting edge".

 

@Venkify

Great! Thank you very much.

 

Hi, Are these states intended? (2.0.0 preview 8)
I am confused because these options are not activated in Sprite Renderer.

 

Hi @Venkify!

We are using 2D SpriteShape for our project for a long time, and we have noticed some bugs (maybe there're bugs, but not sure):
We're creating SpriteShapes during runtime, and we get this error almost everytime:
ArgumentException: shapeParams.splineDetail (0) must be within 4 - 32.
This is weird, since when we print the spriteShapeController.splineDetail, it will be 4, 8 or 16 based on the editor settings of the SpriteShapeController's selected spline detail component (low, medium, high). Although it's value is within 4-32 everytime, it still gives the error. Although both values are meant the same (tessellation of the spline).

We put the BakeMesh() method into a try-catch block, but sometimes the game freezes out, when the mesh is being created.

We are using 2D SpriteShape 1.0.1.4 (for Unity 2018.4.0f1), and we are seeing the 2.0.0 for Unity 2019 maybe solved this problem (https://docs.unity3d.com/Packages/com.unity.2d.spriteshape@2.0/changelog/CHANGELOG.html, in here 1.1.0 mentions "Spriteshape tessellation code is re-implemented in C# Jobs and utilizes Burst for Performance."), which is in Unity 2019, but we can't switch to Unity 2019 for multiple dependencies.

What can we do about this error and/or the freezing? Can we somehow use a newer SpriteShape version for Unity 2018.4.0?


There's another, rare error we sometimes get (ArgumentException: Internal error: Point too close to neighbor), but it's confusing for me about what means "too close". Maybe it can be relative, but if it's a relative thing, then it maybe depends on the width of the curve. Is there a good equation or a minimum point distance we need to use?
Because of it's very rare, I don't think it's causing the freezing of the build, but we don't know.

 

Wondering if anyone knows how to inset the vertices of a spriteshape at runtime?

 

Never mind, figured it out. Here's a script that will allow you to expand or inset the vertices of a spriteshape at runtime:

Code (CSharp):

1.  
2.     public void InsetVertices(SpriteShapeController spriteShape, float offsetDistance)
3.     {
4.         int totalSplinePoints = spriteShape.spline.GetPointCount();
5.         Spline spl = spriteShape.spline;
6.  
7.         for (int i = 1; i < spl.GetPointCount() - 1; ++i)
8.         {
9.             Vector3 lt = Vector3.Normalize(spl.GetPosition(KeepIndexWithinRange(i-1,totalSplinePoints -1)) - spl.GetPosition(i));
10.             Vector3 rt = Vector3.Normalize(spl.GetPosition(KeepIndexWithinRange(i+1, totalSplinePoints -1)) - spl.GetPosition(i));
11.             float a = Angle(Vector3.up, lt);
12.             float b = Angle(lt, rt);
13.             float c = a + (b * 0.5f);
14.             if (b > 0)
15.                 c = (180 + c);
16.  
17.  
18.             Vector3 dir = Quaternion.AngleAxis(c, Vector3.forward) * Vector3.up;
19.             spriteShape.spline.SetPosition(i,spl.GetPosition(i) + (dir * offsetDistance));
20.         }
21.     }
22.  
23.  
24.     float Angle(Vector3 a, Vector3 b)
25.     {
26.         float dot = Vector3.Dot(a, b);
27.         float det = (a.x * b.y) - (b.x * a.y);
28.         return Mathf.Atan2(det, dot) * Mathf.Rad2Deg;
29.     }
30.  
31.     int KeepIndexWithinRange(int i, int total)
32.     {
33.         if (i < 0)
34.         {
35.             i = total;
36.             return i;
37.         }
38.  
39.         if (i > total)
40.         {
41.             i = 0;
42.             return i;
43.         }
44.  
45.         return i;
46.     }

If you want to inset, simply set the offset distance negative. Expand is positive. Code based on the Sprinkler script.

 

Any chance you have the script for this? Trying to figure this out at the moment. Thanks!

 

Which script are you referring to?

 

Thanks. It was 2019.1.0f2 with 2.0.0-preview.8
and It is still being reproduced.

 

Hey, sorry, didn't realize it didn't link to the quote.

It was for generating the normal at a point in on the curve.

https://forum.unity.com/threads/spriteshape-preview-package.522575/page-4#post-3856405

 

Awesome! Great work guys!

 

@Venkify
Cool, are there any release notes? Because this page doesn't list them: https://bintray.com/unity/unity/com.unity.2d.spriteshape/2.1.0-preview.7#release

 

Is it possible to generate points at regular intervals along the spline? To say spawn trees every 'x' distance along the spline itself?

 

Anybody have any techniques on how to set up setup seamless fill to edge transitions for brick or stone walls using SpriteShape? Here's an example of what I'm trying to accomplish:

I can't seem to think of a good way to do it since the filltexture bricks need to seamlessly line up both horizontally and vertically with the edgetexture bricks. For more natural textures it's as simple as feathering the bottom edge of the sprite, but for more man-made textures there's less leeway.

There are a couple cheats I can do to make it look somewhat passable like giving the sprite outline of the side edge sprite extra blank space to help line it up with the fill, but they're extremely limited and not reliable. I was hoping someone had some secret technique that I haven't thought of. But something tells me I'm going to just have to make very precise edges sprites crafted specifically to match the fill exactly and and meticulously shape it in a limited way in order to make it seamless.

 

Hey guys! Just want to share how far I've come using the Sprite Shape Preview Package for procedural generation. All of the objects in the game are being procedural generated along the spline. Also the black cover on the bottom of the ground is copied from the ground sprite shape, with the vertices inset to make it go "into" the ground. There's a few helper functions that could be useful out the gate (like insetting vertices, getting normal of points, getting points at random intervals along the spline, etc.) but overall it's a great basis to develop onto.

I can't see the link (Broken?). I am doing procedural generated race tracks using SpriteShape and I can't determine when the SpriteShape is finished generating. Any ideas nosajtevol how to have a... "on complete callback" or something?

 

Not sure why you can't see it, it works for me! Here's a relink just in case:

https://www.instagram.com/p/Bynj4mpHzyW/

I'm not sure, sorry. I'm actually not generating the ground itself, I'm populating objects on the spline.

 

Instagram was down at the time I clicked ) I dug deeper into my problem and it seems if the camera does not have the SpriteShapeRenderer in its cone, it will set isVisible of the Renderer to false, and NOT trigger OnWillRender in the controller.

A dumb fix is to make sure the camera is looking at the empty SpriteShapeRenderer till it starts generating the mesh. I wish I could have it always render no matter of the camera. Anybody know how?

 

Thank you for replying! I am using 2019.1.7f1, with 2.0.0-preview.8 (2019.1).
I tried calling BakeMesh, I got a lot of errors regarding the Profiler having a Begin call and NOT having an end call OR something about NativeArrays OR calling a previous Job complete before starting another one.

The workaround I have is forcing the camera to LOOK at the SpriteShape and checking if the collider attached has any points. If it has points, then I consider it rendered and then I move the camera on my main actor.

If you tell me 2.1.0-preview7 is a superior version, I can upgrade to 2019.2 (if that is stable enough for production stage). All my code is self-made and I don't use any lib except unity stuff.

 

Hy. We are working on a project in Unity 2018.4.0f1 and using SpriteShape 1.0.14.
(This is the log term support so we can't really change the Unity version)

We have a big problem with Playstation 4 builds:
This example scene looks fine on most of the platforms, but on PS4 only the first part of the edge appears.
With not filled profils it worked fine on every platform.

Can somebody help us with this issue?

 

This only gets the existing points along a spline, does not let me position along the spline at any "percentage". For example if I wanted to move a gameobject along the spline it would be good to be able to calculate its required position based on a percentage from the start.

 

Brilliant, thank you!

 

Thank you for reply Venkify, but I am looking more on something like: scrolling of inside texture filling of closed sprite shape. I think this is very challenging to achieve

 

Greetings

I know I should not be doing this, but I'm testing sprite shapes with 2019.2.0b7 (yep, the Beta) and I'm facing some issues

• For preview.2 - 2.1.0 It works almost all fine, except that the fill material is always over the borders, here is an example of what happens using the example provided by the package https://i.imgur.com/zNOakTc.png
• For preview.6 - 2.1.0 and further, I simply can't use any of it the project: its unable to find lots of types, classes and namespaces inside UnityEditor.U2D, this is an screenshot using preview.10 https://i.imgur.com/zrjYp4i.png, I'm not sure if I should install another package

I'm doing this test using the beta because I'm working alongside the new 2D renderer and the 2D lights, that part works like a charm!

 

@Venkify
Thanks for your update

I'll try to have a sample from my project asap, however I did tried to change the shader to Sprites-Default, it didn't work, also as I mentioned I used the Sample Project that the package manager provides for this package, and it also happens there (see the link https://i.imgur.com/zNOakTc.png for a screenshot, this is not a sprite shape from my project, but from the sample scene), I might need to try a brand new project with preview.2 using the samples to see if it happens in a new project

 

@Venkify ok I tried with a new project, and the sprite shapes in the test project the package provides looks as expected, with the fill material behind the borders

Do you know what can I do to make it look correctly in my project? The strangest thing is: even if I import the package test project in the project I'm working on, the fill material stays at front, it seems to be something in my project that affects all sprite shapes, even the new ones...

 

I found the issue... I also was testing the new 2d lighting system, with uses a custom LWRP asset, switching back to a normal render pipeline (none) gets the sprite shapes to work as expected. Also, I created another LWRP that doesn't use the custom renderer, but Forward Renderer, without luck

 

@Venkify here you go https://github.com/HakS/SpriteShapeBeta7 its brand new with the example scenes taken from the sprite shape package and the render pipeline already set up (the bug happens even without the 2D renderer, just the forward renderer), the bug should be there immediately after you open the Platformer.unity scene

 

hi, i'm a struggling indie dev looking for a way to monetize some of my work

a while ago i developed an alternative shape triangulation method that's done in the shader and I'm wondering if I can sell it to Unity? (compatible with #pragma target 2.0)
it makes it practical and performant for run-time dynamic shapes that can be animated through Unitys native animation workflows.

here's a vid of the shader in action

it was my first game i made as i learned Unity and coding so will need to clean things up if there's interest for it;

please let me know if any body has any ideas on how to best monetize the code without any marketing budget (which i'd probably need for the asset store)
