Official SpriteShape Preview Package

Silly me, yes, that worked perfectly. Thanks.
Been playing with it for a while, looks really good. Going to use this alot.

 

This doesn't seem to be in the 2018.1f package manager?

 

is it available via unity asset store or something? Does not seem to be in unity by default in 2018 version.

 

Is there any way to reduce draw calls? If I duplicate the same SpriteShape on scene it will take up more draw calls. I'm worrying about mobile performance.

 

Will this be available on asset store like cinemachine and others?

 

This is a screenshot from "CastleJumper" example scene. Why does the dynamic batching not work on the multiple duplicated objects with the same material ?

 

Amazing tool!

A feature I would love to have is the ability to control sprites indexes not just by vertices but by segments as well. A sprite index randomizer would be good too. Here's an example of what I mean in ferr2D:

 

This is fantastic, great work!

I have a question, why is the fill texture a texture instead of a sprite? When I try to use the standard shader material we use for our spritesheets on the spriteshape, there is no way to include the texture required for the fill slot into the spritesheet used in the material as the fill slot doesnt support sprites. You can only use one material on the spriteshape, so it defaults to using the entire spritesheet as the fill layer. Everything else works perfect bar the fill layer problem i'm having.

Or is there something I am missing?

Thank you!

 

Hi @Venkify ,

There's a small bug/annoyance: When you change a sprite's settings (pixels per unit, sprite shape, etc) the SpriteShape does not get redrawn until you edit it.

I also have a question. I would like to move something along the spline, with the controller's current detail level (or even a custom detail level). Is there an easy way to do this, or will I have to dive into the scripts to figure it out? A Spline.Evaluate(int pointIndex, float progress, int detailLevel) method might be a useful addition.

It might even be a good idea to move the Spline class to core Unity at some point, as it's likely to be useful for many uses besides SpriteShape.

 

Thanks - I already figured that out, but I still think a helper method that passes along the right stuff would be useful in the package.

Here's how I did it, could be easily adapted :

Code (CSharp):

1.     public static Vector3 FindPoint(int index, float progress) {
2.         while (progress >= 1) {
3.             progress--;
4.             index++;
5.         }
6.         while (progress < 0) {
7.             progress++;
8.             index--;
9.         }
10.  
11.         index = Mod(index, instance.spriteShapeController.spline.GetPointCount());
12.  
13.         Vector3 startPoint = instance.spriteShapeController.spline.GetPosition(index);
14.         Vector3 endPoint = instance.spriteShapeController.spline.GetPosition(Mod(index + 1, instance.spriteShapeController.spline.GetPointCount()));
15.         Vector3 startTangent = instance.spriteShapeController.spline.GetRightTangent(index);
16.         Vector3 endTangent = instance.spriteShapeController.spline.GetLeftTangent(Mod(index + 1, instance.spriteShapeController.spline.GetPointCount()));
17.         return BezierUtility.BezierPoint(startPoint, startPoint + startTangent, endPoint + endTangent, endPoint, progress);
18.     }

 

This is marvelous.
I hope there is documentation about how to use Sprite Shape Profiles correctly.

I just tested the collider.
It doesn't work. I thought it supposed to create collider automatically, right?
What does the meaning of collider?
I added physics2D manually and it is now better.

When will this preview become extension/package?

 

You need to add a polygon collider yourself, but the spriteshape can update it automatically with the given settings.
Note that when you check "update collider" it does not update it automatically when changing the shape through script.

 

Great feature, i realy love it !

I don't understand how the corner textures mapping is working, i have an interval between my textures and i dont manage to ajust it to have somethings with nice look.



For now, i dont have any problem with the tool.
A little feature that would be nice in the final version : When we update the sprite in the sprite editor, the spriteshape is not updated, i have to restart unity everytime i ajust my texture, it would be nice if it was done automaticaly.

 

Hello,

I had just downloaded the package and I'm having an hard time trying to add a collider. I mean, I can add an edge collider for instance, but it will appear as a straight line and I will have to "map" it along the SpriteShape which can be a very tedious task. I tried to add a composition collider but the "generate" button does not generate anything.

So, what is the best way to add a collider to a SpriteShape ?

Thanks

 

Use a polygon collider and check "Update Colider" in the sprite shape controller settings.

 

Thanks !

 

Hi, I am trying to create a platform with this tileset. The tiles are 64x64.
Top row:
Bottom row:

I am getting this atm. I followed the documentation.


Thanks for the help. I was also wondering if there is going to be some sort of video tutorial on it?

 

This looks really cool, could it be used to have 2d ropes?

Ive been doing some testing with the hinge joints which works well for a chain, but once you want HD rope which has no natural "chains" I need something to smooth out for each node of the hinge joint.

Ideas and how to implement would be greatly appreciated.

 

If i also insert some points by script the SpriteShapeRenderer has a "Center: (0.0, 0.0, 0.0), Extents: (0.0, 0.0, 0.0)" boundary therefore it doesn't draw anything in the game view until i double click on the gameobject in the hierarchy while the scene view is actvie.
I also tried to call a BakeMesh() after the InsertPointAt() function call, but i get "Assertion failed: Assertion failed on expression: '!m_HasActiveGeneratorJob'
UnityEngine.U2D.SpriteShapeController:OnWillRenderObject()" errors.
it ocures in Unity 2018.1.2f1, windows10

 

Thank you for your response. I find a solution, if any camera looks at the origo during the generation, it works fine.

 

I was wondering what term is used to call this technique. Is it sprite deformation?

 

So is there any way to use a custom material and have the sprite shape be fully functional including a fill texture?

 

Hello

I have (hand drawn) images whose shape I want to use to create GameObjects with the same shape using SpriteShape , to save on file size.

How can I do this?

a. I do not know how to convert the vertices of the source image which are a Vector2 array to Vector3 as required by the Spline.InsertPointAt method.

b. I do not know how to Generate a new Object with the shape derived from the above vertices info. So I tried adding points to the spline of an existing GameObject with SpriteShapeController already attached using Spline.InsertPointAt but If i try a mock value of Vector3(3f, 4f,0f) I get the error
ArgumentException: Internal error: Point too close to neighbor
UnityEngine.U2D.Spline.InsertPointAt (Int32 index, Vector3 point)
Unity/cache/packages/staging-packages.unity.com/com.unity.2d.spriteshape@1.0.10-preview.1/Runtime/Spline.cs:58)
ShapeSource.Start () (at Assets/ShapeSource.cs:31)

I have an image that I imported and got its vertices

Code (CSharp):

1. sourceSpriteRenderer = GetComponent<SpriteRenderer>();
2.         sourceSprite = sourceSpriteRenderer.sprite;
3.         Vector2[] sourceVertices = sourceSprite.vertices;
4.  
5. targetSprite= GameObject.Find("target");
6. SpriteShapeController targetSpriteShapeController = targetSprite.GetComponent<SpriteShapeController>();
7.      Spline targetSpline = targetSpriteShapeController.spline;
8.  
9.         Vector3 m_vector3 = new Vector3(3f, 4f,0f);
10. targetSpline.InsertPointAt(targetSpline.GetPointCount(), m_vector3 );
11.  

I created an empty game object called "target", attached the SpriteShapeController and added 3 points to the Spline manually
The First Point at Index 0 has Point Position (x=-12.90, y =0.95)
The Second Point at Index 1 has Point Position (x=1, y=-3)
The Third Point at Index 2 has Point Position (x=0.25, y=1.6)

and tried to add a fourth point by script, but got the Internal error: Point too close to neighbor


I am a complete beginner so apologies for the elementary questions.

 

Hi,

Thank you for great asset.

Two problem i have :

1. When i save scene i get error:
Assertion failed: Assertion failed on expression: '!m_HasActiveGeneratorJob'
UnityEngine.U2D.SpriteShapeController:BakeMesh(Boolean)
SpriteShapeAssetPostProcessorHandler:OnPostprocessAllAssets(String[], String[], String[], String[]) (at /Users/igor/Library/Unity/cache/packages/packages.unity.com/com.unity.2d.spriteshape@1.0.10-preview.2/Editor/SpriteShapeAssetPostProcessorHandler.cs:18)
UnityEditor.AssetPostprocessingInternalostprocessAllAssets(String[], String[], String[], String[], String[])

2. Sometime on some objects corners is not work. I switch Corner to Automatic/Disabled, try to remap corners in material - it is not help (Point and neighbors points are "Straight line from point to point" selected).

How i can fix this problems?

 

I know that this is still experimental development, but those who tried it, is this stable enough to integrate it into a production pipe line?

heads up on 2018.2.0.x - Prefab preview :

I know that version is experimental but a heads up for early adoption to their new API would be good.
thanks

 

Great cannot wait to play with this, but where are the samples you mentioned in the first post.
I cannot find anything in the package!?

Hey guys, do you think it's possible to get the sprite index of a precise point on the spline?
I have a ball that bounces and I would like to know if it touches the red or the blue color (so sprite with index 0 or index 1) as you can see in the screenshot.

Any ideas?

 

I found the problem. If neighbor points has height not equal 1 - corner not shown. If points has different height - corner not shown.

 

I just noticed that it's not possible to use the shape generated as a sprite mask because the sprite mask requires indeed a sprite, and not a sprite shape.

Is the shape baked into a sprite once the build is complete?
Is it possible to access the sprite generated by the sprite shape in a Start() function and then assign the sprite to a sprite mask?

Thanks.

 

I'm seeing a bug where calling SetPosition or InsertPointAt doesn't update the actual mesh at runtime for WebGL builds. Is this a known issue and/or is there a workaround?

 

Thank you for the preview of SpriteShape.

After adding points in a SpriteShape to form the outline of a lowercase 'e' (image below), what would be the way to add points to form a transparent hole in the letter?

 

Thanks for the heads-up. Does anyone know what namespace "PrefabTypeUtility" lives in? I'm having trouble accessing it.

 

I think so too - but that's what I'm using. I'm getting the same API warning as @Jiraiyah, but can't find how to correct it.

 

I reported the bug and attached a repro project, but I wanted to add that this seems to affect all build platforms for me.

I tested with a Windows executable and WebGL and neither of them seem to update my spline points at runtime, even though it works during Play mode in the Editor.

Has anyone else encountered this?
