Official 2D Animation 7.0 released for Unity 2021.2

i found out that spriteskin is so bad

 

i will tell the info later ,, btw


i cannot install the burst

 

curently i used unity 2020
i make a lot of spriteskins because itry to make leaf that has spring bone
.
ah so i have to use unity 2021 ?

 

[Package Manager Window] Cannot perform upm operation: Package name 'com.Unity.Collections' is invalid. [InvalidParameter].
UnityEditor.EditorApplication:Internal_CallUpdateFunctions ()



i already used 2021.2 but i can not install the collections package

 

does burst works with net 2.1 ? i watch the tutorial about burst and he said that the api must be 4

 

i dont know how to install collection in 2019 ,,there is no instal by name in package manager ,,
i failed instaling burst in 2020

im succass in 2021 but the scene vew seems buggy
( it is not like usual in previous version ,,extremly very hard to control just game object in hierrarcy ) sometimes the tools doesnot appears so have to do it in transform

 

ah ok iwill try this method https://docs.unity3d.com/Packages/c...5804257.1603346014#optional-performance-boost

 

finnaly i can install it in 2020 ,thanks

 

Hi, I'm loving the 2D animation package, thank you for making it!

I was wondering if you could help me out with an issue I'm having. I'm doing a project that will ultimately be on WebGL. I have a character that animates with bones and skin and that all works great. What I want to do is give the user the option to upload a png to create a custom skin for the character.

What I'm currently doing is that I have the Texture2D loaded into memory(?) and I am creating a sprite out of it with Sprite.Create() and trying to swap it into the character via SpriteLibarary.AddOverride. I get this error when I try to do this. (Note: I am testing in Unity Editor, and I'm using package version 5.0.9 because I can't upgrade to 2021)

----------------------------

This is the code I am using below:

public void CustomSkin()
{
customSprite = Sprite.Create(texture2D, new Rect(450, 50, 1150, 1600), new Vector2(0.5f, 0.5f), 100.0f);

string referenceLabel = targetResolver.GetLabel();
Sprite referenceSprite = spriteLibrary.GetSprite(targetCategory, referenceLabel);
SpriteBone[] bones = referenceSprite.GetBones();
NativeArray<Matrix4x4> poses = referenceSprite.GetBindPoses();
customSprite.SetBones(bones);
customSprite.SetBindPoses(poses);

const string customLabel = "customTorso";
spriteLibrary.AddOverride(customSprite, targetCategory, customLabel);
targetResolver.SetCategoryAndLabel(targetCategory, customLabel);
targetResolver.gameObject.GetComponent<SpriteRenderer>().color = Color.white;
}


The odd thing is that it all works if I create the sprite a different way: customSprite = Resources.Load<Sprite>(texturePath). By loading the texture as sprite from the Resources folder I get no issues. The problem with this workflow is that if I want my user to upload via WebGL, I can't save that png to resources and then load it from resources (at least my understanding is that I can't save anything into Resources folder during runtime).

If you have any suggestions or can let me know what I am doing wrong, I would really appreciate it. Thank you!

 

Hi Ted. Thank you for such a quick reply! I appreciate it.

I tried the code you added and it worked great! I didn't get the error and the sprite now moves with the bone. The only issue I am having is how the sprite is cut out of the PNG. For example, in the image below, I tried to replace the forearm sprite with the one that is part of a custom PNG. The whole PNG got attached to the bone. I tried to modify this by changing the Rect details in Sprite.Create by calculating where the Rect cuts would be on the original PNG. However it was very hard to guess and I realized that Unity had packed the sprites in a rectangle and not the original square I had (image below). The problem is I'd love for there to be a standardized skin template that I could have, but because Unity packs the sprites in a different locations and shape, it seems hard to make it all match.

Do you have any suggestions on how I can fix this problem? Is there a different sprite setting I need to do at import? Or something I can do with C# that could give me the data I need to input into the Rect dimensions?

Lastly, regarding the last image, is this what you meant when you said to be cautious when blending weights - (the torso sprite is connected to two bones and when I move the child bone the torso starts to blur and stretch). Is there any way around this? Or would you suggest just keeping 1 bone per 1 sprite in order to avoid this issue?

Thank you so much!

Hi.
Is it possible to have a Single Sprite rigged with more bones and animate the part of the sprite that is arounf the bone ?
Or is it doable by effectors or other 2D features ?

For example I would like to have a bone on a tree branch and animate only that part (without cutting it separately in photoshop).

Thank you

 

Please specify a step by step workflow becasue in docuemtnation is not very straightforward.
At the moment I did this:
1. autogeerated geometry
2. create the bones i needed
3. created vertices so i encapsulate each bone like in a box
4. now i should paint the weights

3 -- i am not sure if this is the correct way to put the vertices
4 -- how should i paint the weights ?
>> do i select each bone and paint the 4 vertices that encapsulates the bone ?

 

I also have the sme problem on rendering the normal sprite. It simply vanishes and I only see the bones. Why ?

edit: for others who enter here: there must be weitght paint on everything else it wont show the sprite.

 

How to move an edge collider 2d with the bones ?
I have the collider and an effector on a separate GO.
I tried to have this go as child to the bone root but it doesnt move as expected.
I think there shoudl be a way to autogenerate a collider around the bones, becsaue I do not see any other solving.
Any ideas please ?

later edit: i put a box collider on every single bone GO. They do move ok with every encapsulated bone.

 

Hi Ted, thank you so much for answering my questions above! I have a follow up question. I got the script to work (to switch texture/sprite during runtime). It works great for the .psb sprites. Now I am trying to use a modified script for a .png file (set to single mode) but am getting strange results - the texture is stretched and deconstructed and the bones are effecting parts they're not supposed to.

How different are the copy processes when using .png vs .psb? I understand that png doesn't use the sprite library asset, so I deleted that part of the code, but other then that, not sure what I need to alter. Any help would be greatly appreciated! Also, is there a good resource that goes into depth about this? The Unity API/documentation doesn't really have a lot of info in it.

Thank you!

 

Hi Ted, thanks for the quick reply. In this example I am actually working with just .pngs and all are laid out completely the same. They have the same exact size too (1024x1024). That's why I find it odd that I am getting these issues. Does this have anything to do with the issue of the version of 2D animation package / unity I'm using? I'm currently using 2020.3.17f1 and package 5.0.9.



Totally understand that most users wont do this. But it does seem like copying and creating sprite data during runtime is a must for this package.

The .psb code I was using previously worked great. I am trying to modify it to work with PNGs. This is what I have for the PNG version:

Code (CSharp):

1.  
2. Sprite CreateCopySprite(Sprite origSprite)
3.     {
4.  
5.         var newSprite = Sprite.Create(SimpleTexture2DCopy(originalTexture), origSprite.rect, new Vector2(0.5f, 0.5f));
6.  
7.         //Inject Bone Weights
8.  
9.         var vertexCount = origSprite.vertices.Length;
10.         var blendWeightArr = new NativeArray<BoneWeight>(vertexCount, Allocator.Temp);
11.  
12.         var blendWeightRef = origSprite.GetVertexAttribute<BoneWeight>(VertexAttribute.BlendWeight);
13.         for (var i = 0; i < blendWeightArr.Length; ++i)
14.             blendWeightArr[i] = blendWeightRef[i % blendWeightRef.Length];
15.  
16.         newSprite.SetVertexAttribute(VertexAttribute.BlendWeight, blendWeightArr);
17.         blendWeightArr.Dispose();
18.  
19.         //Copy Bones and Bind Poses
20.         newSprite.SetBones(origSprite.GetBones());
21.         newSprite.SetBindPoses(origSprite.GetBindPoses());
22.  
23.         return newSprite;
24.  
25.         //spriteLibrary.AddOverride(newSprite, origSprite.targetCategory, origSprite.customPartLabel);
26.         //origSprite.targetResolver.SetCategoryAndLabel(origSprite.targetCategory, origSprite.customPartLabel);
27.         //origSprite.targetResolver.gameObject.GetComponent<SpriteRenderer>().color = Color.white;
28.     }
29.  

As far as I can understand, it seems the mesh is not copying correctly - below is the wireframe version. The original on left, and the newly created sprite (PNG single) on the right. Unfortunately, without documentation, I am completely blind as to how to make it work. Any help would be greatly appreciated. Thank you.

 

Hi Ted, that worked perfectly, thank you so much for your help! It's an amazing package, looking forward to building so much with it!

 

Ok I definitely will share!

Just one last quick question. For the PNG single mode skeleton set up. Is there any way to hide a body part attached to a bone? For example if I wanted to hide the hand I would usually just turn off that Sprite Renderer or disable the game object. But since the PNG set up just has one Sprite Renderer, its either everything is on or everything is off. Is there a way go about it via script? Similarly, is there a way to change the depth of the bones at runtime via script?

Thank you!

 

@Ted_Wikman
I'm struggling to find a way to use this for 2D sprite sheet animations and swap for different sprites like equipment. For example, I have spritesheets that need to be layered on each other for each part of a character.

Consider these sprite sheets as an example:


The flipbook style animation sample is similar, but that doesn't include layers for equipment, just swapping entire sprites.

Ideally, I'd have something like a SpriteLibraryAsset for each type of sprite sheet (Body, Hair, Pants, etc). I can categorize them by their animation (MoveUp, MoveLeft, MoveDown, etc.). The label might just be the frame number.

Then I might have a higher order SpriteLibraryCollection that can contain multiple SpriteLibraryAssets.

In any case, I can't seem to extend this easily because SpriteLibrary and SpriteResolver make some assumptions on resolving each other and a one-to-many relationship. I think I need a many-to-many type thing.

Additionally, recent updates changed to use SpriteKey for animation. This makes it harder to reuse animations across different categories since the key is now a hash of both category and label. Previous, I was attempting this:



This way I could use a convention for my Label (0,1,2,...) and animate it each keyframe. Then I could set the Category to my "collection" or equipment set and the right animation frame. With SpriteKey, I can't do that.

Is there any supported way to do what I want today using this package?

 

@Ted_Wikman

After a lot of trial and error, I did get it to work exactly as you mentioned.

I created multiple game objects for each "layer" of the character I wanted to have. Each of those objects has a SpriteRenderer, SpriteLibrary, and SpriteResolver.

I swap out the SpriteLibraryAsset for each object, which corresponds to a rendering layer like base, helmet, chest, etc.

The SpriteLibraryAssets have categories for each Animation name I support, and I enumerate out each sprite on the frame number. This means I can re-use the animations, just as you stated.

The SpriteLibrary / Asset are a little clunky to work with and it's very tedious to setup, but so was the key frame animations with the Constant tangent changes for every keyframe.

I'm happy it works though, thanks for the support! Something like this would make a great addition to the samples provided.

 

I'm interested in the answer to your general problem as well.

In absence of the kind of control you seem to be looking for (I would like to have that too), I can offer you a possible solution that I think would work. We are doing something similar but on rigged 2D avatars to achieve different colored eyes, hair and clothing, and not frame by frame, but I think the general idea is the same:

Use secondary textures for the equipable items. For example: overlay your pants in a secondary texture. You then have to control the color (and visibility if you want to make them invisible) using a material, and you would swap materials to change pant color. I wrote a Shader Forge that colors secondary textures, and you could add as many secondary textures as you need for the different equipment items.

The big drawback I have found is that secondary textures have to be edited separately, and it would huge time saver if they could imported from layers in a PSB.

 

@Ted_Wikman what is the path forward with this 2D Animation 7.0 update? I guess I don't quite understand how I should handle this:

One of my clients is doing a game and I adivsed them at the outset that we should use 2020 LTS because we could be assured that this version would be supported into the reasonable, foreseeable future.

Now this 7.0 update comes along but is only available for Unity 2021. This update has features what will save them a huge amount of development time but at the cost of abandoning the perceived stability that the LTS release provides. So now we are between a rock and a hard place.

I've never gotten a clear handle on the logic of why Unity produces all these versions, and for example why this update was only made available for 2021 and later.

So what gives and what would you recommend?

 

@Ted_Wikman thank you so much for your clarifications - that clears up quite a bit for me! Also, I didn't catch anywhere that a 2021 LTS version was coming.

A couple of Questions:

I have read that the intent with LTS versions is to provide support, updates and fixes, for 2 years. I take it that is irrespective of the actual version number? That is if Unity 2021 goes LTS at the end of 2022 year, support would continue to the end of 2024?

Well as I am "the Studio" I know what I will tolerate as far as editor instability but I am not sure what you mean. I 'm concerned about features that I have gotten to work in one version and that change or don't work in another version. That and Build stability!

Is this the instability you refer to, or you are talking more about editor crashes and unknown bugs?

 

All you need to know about: "Verified"



P.S. I have no idea what of the forum branches now to write
-2D Animation was now scattered on dozens of dozens of non-interconnected threads!

 

А long time ago in a galaxy far far away...

I hoped that a new package of 2D Animation on the basis of the Anima2D you just purchased (then)...
-Native AnimationPackage created by the developers of the Unity itself(!),
this is about to make something like this very-very soon:



Just look this video on YouTube, there is all the possibilities of this Rig,
He is amazing:

But... The years went... and even the simple FFD is not even in the plans...

And... Now you explained the Reason... And your whole Plan!
At the same time, practically killing Hope...

-The hope that I will live long enough to live until the moment when I can see something like that in Unity with my own eyes!

And it makes me very very sad...

 

I am using the skinning editor to create bones for my character but the animations required by my character vary significantly (e.g. the combat is very different from the walk, etc.). For example, the combat animation is very complicated and might need to add some hand-drawn sprites to make the animation smooth. Do you have any suggestions on how to handle this situation? Thank you!

 

I'm curious about the licensing state of the Triangle.NET code that was included in this package previously ( up to v6 ). V7 seems to have dropped it completely, and it seems now a UTess namespace in the 2D Common package performs the triangulation/tesselation tasks - is this assumption correct ?
That leaves my main question: Is/was the reason for this change the somewhat unclear licensing state arround Triangle.NET ?
If yes, where would this leave us Unity developers in regard of a potential licensing breach while using the old 2D Animation packages in our commercial projects ? Is there some (offical) word about this ?

Just for completeness: Triangle.NET is a C# port of the following code http://www.cs.cmu.edu/~quake/triangle.html
And on that page its states the following regarding licensing

 

initial changelog for V7 contains the following

So looks like at least part of my assumptions are correct

 

Hi. Apologies if this isn't the right thread to ask this, but can the imported PSBs be atlased? I can't seem to do it. I understand that internally, Unity already generates a sprite sheet per PSB file and that acts as an atlas of sorts, but there would be some benefit if we could combine multiple into a larger sprite atlas. If possible, please point me to the way? thx
