Official 2D Sprite Shape is out of preview for 2019.3

Thanks for the quick reply! Doesn't work with this setup (see attached pictures). The variant doesn't show up in the inspector? Only when I click some points (the ones in the upper left corner)?



Edit: I found why, I'd have to add a null/none sprite to every angle. But now my inner corner looks weird where the seem is? See attached picture "inner corner".

Do you think the "inverse" option could work by creating an enclosing box around the drawn shape like in this picture below. (And maybe it would be a lot more user-friendly for level designers than the steps above) I've seen this in assets before, but they are all obsolete now.

 

Thank you I understand now, but what about the missing fill texture under the corner?
Still using the same configuration as above (https://forum.unity.com/threads/2d-...preview-for-2019-3.818799/page-3#post-6870950)

 

Hi! First of all thank you for this helpful package. It saved me from having to do a bunch of things myself.

I have a case where I need to rebuild a shape at runtime, sometimes every frame. Moreover, the number of points in the spline can be different.
1. I looked at the package code and couldn't find a reason why SplineControlPoint has reference type. Changing it to value type would help reduce the number of memory allocations for high dynamic use cases.
2. The situation when two adjacent control points have a close position is considered an error. But why not weld them together with degeneration of inner tangents?

 

Is there a way to force render the sprite shape? Kinda like a SkinnedMesh "Always Render".

I'm getting issues where the sprite shape stops rendering after it leaves camera. The user can "fly" up above the terrain and it causes the sprite shape to leave the camera for a bit. When the user falls back down, the sprite shape stops rendering.

 

@Venkify is it possible to create the spline for sprite shape from a composite collider?

I have a bunch of polygon colliders, merging them with a composite collider, and wanted to outline the result with a sprite shape.

 

Can’t you loop through each point of the composite collider and add that to a sprite shape?

 

is it a case of simply copying over a List<Vertex2> or is there a lot to it? Just wondering if theres already a script for this, making a shape from an existing shape seems like a common task

 

https://docs.unity3d.com/ScriptReference/CompositeCollider2D.GetPath.html

A composite collider can have multiple shapes so each path should be one spriteshape i guess. I don’t know if there is a script for it but it shouldnt be too hard

 

Figured it out, thanks

 

ok next question How to smoothen ShapeTangentMode.Continuous? When set in code, these draw the same as Linear.

I noticed theres a smoothen function in extras by @Venkify

https://github.com/Unity-Technologies/2d-spriteshape-samples/blob/master/Assets/Unity Technologies/2D SpriteShape/Extras/Scripts/SimpleDraw.cs

However this is for a specific purpose and not suited to a non-open ended shape

 

two more feature ideas...

1. please make it possible to use the Sprite Shape Renderer as a Sprite Mask or,
2. please make it possible to have convex sprite shapes. (holes)

I'm running into these two road blocks on a top down game, it's awkward to use sprite shape as organic shaped walls... it seems to be only designed with platformers in mind... I want the fill on the outside and the path sprites on the inside (as mentioned a few times in this thread, the fix at the top of the page is no good for me as the walls are randomly generated)

Being able to use a Sprite Shape Renderer as a mask would instantly solve this problem as I could just punch a hole in a sprite and use the same shape on another object to draw the profile

 

@Venkify I get an error when trying to dynamically make a shape, sometimes I get this:

ArgumentException: Internal error: Point too close to neighbor
UnityEngine.U2D.Spline.InsertPointAt (System.Int32 index, UnityEngine.Vector3 point) (at Library/PackageCache/com.unity.2d.spriteshape@3.0.15/Runtime/Spline.cs:60)

This would be a major problem in a game, as it crashes the playloop. Instead of crashing because points are too close, could they just be skipped or merged instead?

I can check my points that I am feeding it, however how close is "too close"?

 

So I figured out a pipeline for doing inverse sections, it's not an extension for Sprite Shape but rather a work around:

1. fill your "inverse" sprite shape with some color
2. set it to a unique layer
3. add a new camera and set it to only view that new layer
4. render the cameras output to a render texture
5. in code, use the rendertexture and generate a new sprite from it using tex2d
6. apply that sprite in the same position as your sprite shape on a new sprite mask
7. make another tiling sprite using the fill sprite you want as your wall, set it to draw only outside the mask, or set where you want the "hole" in another sprite shape and set that to only draw outside the spritemask.
8. make a duplicate of your sprite shape and invert the path tiles
9. run scene

I'm doing this at runtime and works perfectly, you could probably get it to run in edit mode too.

 

why don't make spline or such tools as intuitive as Ferr2D or
Spline Terrain 2D: https://assetstore.unity.com/packages/tools/sprite-management/spline-terrain-2d-122383

Also, I don't find many people use sprite shape is there any reason? Also if you look at assets using spriteshape there is very little when compared to tile sets. I think unity developers can do much better with spriteshape. Hope it gets better and popular.

 

Hi,

I am using 2D Sprite Shape 5.1.2 in my game, Unity version 202.3.7f1

The sprite sprites are dynamic, which are composed of 2D physics rigidbodies.. and are modified at runtime

I have fill tessellation enabled, since it optimizes the CPU greatly and gives me a good 60FPS on low-end devices. My SpriteShapes fulfil the criteria for "Fill Tessellation" which is
1 - Dynamic sprite Shape
2 - No overlapping edges or duplicate points

Yet, the game gets stuck randomly on all the platforms, be it Unity editor, Android or iOS device. And there are no crash logs. To me it seems like the Fill Tessellation Jobs run into some "race conditions"

Could it be that I am modifying the shape in "Update" method, which causes this issue? Should they be done in "FixedUpdate" because of physics or LateUpdate?
Or do I need to call some method after modifying the shape? This is how I can updating the shape

Code (CSharp):

1. private void Update()
2. {
3.         int totalPoints = ShapeSpline.GetPointCount();
4.         for (int i = 0; i < totalPoints; i++)
5.         {
6.             ShapeSpline.SetPosition(i, edges[i].transform.localPosition);
7.         }
8. }

Thank you and looking forward to your reply

 

Hey thank you for the quick reply, I will try this and see how it works. I will try to file the bug sometime next week since I need to strip out this part from the project

 

Hi, first of all sorry I haven't yet made the sample demo the issue, but I opted on not using the Fill Tessellation option.
While the game works fine, I am running into another issue. I get the follow exception

InvalidOperationException: The previously scheduled job SpriteShapeGenerator writes to the Unity.Collections.NativeArray

Maybe this is the problem here?
https://forum.unity.com/threads/the...-call-jobhandle-complete.660160/#post-4419259

Thank you and looking forward to your reply.

 

Hey were you able to find a solution for the exterior & interior image?

 

see my solution above.

 

Why doesn't Sprite Shape respect the editor's grid snap toggle?

In my project I found that I need to snap practically every point in every shape to the grid. There's a lot of shapes in a level, as you can imagine. This is currently a very, very painful process:

Every time I select a shape for editing I have to click the Snapping checkbox (which always resets back to unchecked whenever a shape is selected). I have a 5K display. The checkbox is tiny. I have to do this to every shape every time I want to change something.

Sprite Shape goes through the trouble of disabling the global grid snapping option when the shape editing button is clicked. The setting is then very politely turned back on when the user exits shape edit mode.

In my opinion the snapping toggle should not be in the inspector in the first place. It's not a persistent per-object setting, the checkbox is only visible while the shape is being edited in the scene. Moving points and snapping them to the grid should be considered tool-level functionality that should respect the settings of the editor's grid snapping settings, as one would expect.

Sprite Shape does use the unit increments specified in the editor's grid options for snapping, it just overrides the current state of snapping and decides that it should be off, always. Is this just a bug?

I tried to hack a custom keyboard shortcut for checking the snapping option in the inspector, but the logic is buried so deep in the code that I gave up on it... I did discover that there's a few handy undocumented(?) keyboard shortcuts for Sprite Shape, though (search for spriteshape in Shortcuts to see these). Alas, no shortcut for snapping.

 

This is great news, much appreciated!

 

@Venkify any plans on adding this feature? Other terrain tools like Ferr2D and Spline Terrain 2D have this

Possible to do with the workaround mentioned, but that is just extra work and processing

 

Sorry for the late response, me and my team are still struggling with interiors/inverted shapes (since start of this year). We are creating rooms with venkifys workaround below (but hoping every month there comes a fix/better solution. I still don't get why Unity won't add a checkbox to invert shapes):

 

Hi! Another feature request..

Can you add an option to re-align pivot to at least center? While creating a shape, almost all the time the pivot goes way off

 

This would be great! In the meantime, I do have this script that works pretty well.... It doesn't keep the terrain in the same place but it does center the pivot.

Just add this script to your Editor folder and use it like this:

Hope it works!

 

Thank you so much for this !
The pivot points were driving me insane for days xD

 

Thanks, works well!

 

[ Update ]
I was curious and did a performance test to see how far I could take sprite shapes before the fps took a hit.

In no way is this definitive, only an extreme test on my end to see what kind of performance is affected. Thought I'd share the results. In the end, despite the deceptively simple ease of use and results, sprite shape can be a bit taxing on the fps, if abused.

The original goal was to see if I could make the entire level with sprite shapes, because of sprite shapes nice curved profiles. (Foreground, middle ground, background and sky\clouds) In the end perhaps it'll be a combination of planes and limited sprite shapes.

Obviously the editor loop will affect the performance too.

Also I'm not sure if dynamically disabling\ enabling out-of-camera sprite shapes would have improved performance. Didn't see that type of option in the sprite shape settings.

[ Test scenario ]
Empty scene with camera and closed sprite shapes or planes.

About 800 closed sprite shapes
- 15 fps average
- max time ms 18.50


About 1000 planes
- 200 fps average
- max time ms 2.69



[ Update End ]



Is there a way to dynamically occlude the sprite shapes when out of camera view? Kind of like how mesh renderers have the checkbox to dynamically occlude the mesh.

 

If anyone is having problems with sprite shapes becoming invisible (randomly stopping to render, and then start again), check the visual bounds recalculation workaround here: https://forum.unity.com/threads/spr...the-sprite-does-not-show.586453/#post-7270162

 

Is it possible to offset only the collider for a spriteshape, on a single edge?
For example if I want my collider offset to be zero, except for the bottom edge which should be 0.5f?
I'd also like this offset to be applied only to the collider, and not to the sprite for the bottom edge.

I know you can set an edge sprite's pivot point which will adjust both the position of the sprite, and the position of the collider edge. But in this instance I would like to just modify the collider, and keep the sprite's pivot at zero.

The attached image shows a spriteshape where I'd like the bottom edge to extend all the way to the bottom of the sprite, but keep the sprite itself for the bottom edge positioned where it is now.

 

It would be amazing if the SpriteShape mesh could be used with SpriteMask to define the shape of the mask rather than needing a custom sprite for every mask you want to have.
