[DEPRECATED] Anima2D - Advanced 2D Skeletal Animation Plugin

Hi, is it possible to use/convert or migrate a spine project to anima2d.
I have some nice assets that are animated with spine, but I want add some additional animations.

 

Looks very intuitive, I wish there´s a 3D-solution like this, too.

 

Hey sacb0y, I didn't see where you got a reply, and I just had to troubleshoot this one myself. On the Spring Manager, click the stiffness and drag curves and add a curve value to both. The script isn't correctly accounting for empty values there, and/or defaults are not being set.

You'll also get an index error if you Play without dragging spring bones into the manager array. And I also had to check "is use each bone force" on each to get the behavior I wanted after that.

You could edit the script to account for empty arrays/values, too. Hope they fix the script, or make a more official one without those issues in a future release. If not, I may get in there and tweak it.

Hope this helps (although several months late).

 

Hi Sergi_Valls! Thank you very much! I am testing the patch!

 

Hi there! Mby my question not related to Anima2D, but I try...
Can anyone tell me, how to make slasher-game-style animation for weapons?

 

Hi Sergi_Valls! I made some tests.
At the first launch of project with the patch all was fine, and it worked, "Windows\Anima2D\Baking animation" was enabled.
All next launches problem had come back. I did not used pose manager at all. "Windows\Anima2D\Baking animation" - disabled.

"Windows\Anima2D\Baking animation" - disabled.

 

Hello everyone, i want to make an animation arm of my character with anima2d IKs. Shoulders of arms have armRotation script (has LateUpdate). It rotates with mouse. When the IK animation of hand plays, shoulders are rotating. But there is a problem. Animation does not works at shoulders. It works only on hands. Please help.

 

Also, is there any difference in performance between spritemesh and sprite renderer? We can use sprite renderer on bones by adding it to new object.

 

Hi Sergi_Valls, more bugs then were =( Angles zeroing out, 360 rotation...

 

Greetings,

We're having some issues with our dog character's legs with Anima 2d. His feet and legs are rigged up with 2 IK Leg objects to make the three-jointed legs, and they appear correctly in the preview/work area (animations cycle correctly and everything looks fine), but get botched when you press "play". Everything works normally, only three of his four feet are pointed in the wrong direction. Could anyone point us towards the right direction in solving this? We're scratching our heads as to why it happens for every leg apart from one. I looked through the Anima 2d tutorials and some of them (the one with the t-rex) looked like three-jointed legs should be possible. Any thoughts?

The IK's for the legs are all IK Limb 2D's with their weight set to 1 (seems to be the default since I didn't change it manually, and it also seems to be the slider's maximum value since you can't go above 1) The lower IK's are set as "Flip", as well as the dogs front legs' upper IK's, to get the 3-jointed legs, but in the back leg's upper IK's the "Flip" option is left unchecked. Curiously enough, setting the "Weight" to 0 for the lower IK's makes them flip out the same way. The problem is that everything looks and animates fine in the Scene window, but the legs bug out when you press play on the scene, and when you export and run the game.

How the legs look in the Scene window:



How the legs look after pressing "play":


The structure of the GameObject - the sprite meshes, the IK's and the bones.


Much thanks in advance, Anima 2d is a powerful tool.

EDIT: Clarifications

 

Hi! Try "Flip" and decreasing Weight to 1 if you use IK Limb 2D.

 

Thank you for your reply! Sorry, I should have been more precise with my description of the issue. I will update my original post to include this too:
The IK's for the legs are all IK Limb 2D's with their weight set to 1 (seems to be the default since I didn't change it manually, and it also seems to be the slider's maximum value since you can't go above 1) The lower IK's are set as "Flip", as well as the dogs front legs' upper IK's, to get the 3-jointed legs, but in the back leg's upper IK's the "Flip" option is left unchecked. Curiously enough, setting the "Weight" to 0 for the lower IK's makes them flip out the same way. The problem is that everything looks and animates fine in the Scene window, but the legs bug out when you press play on the scene, and when you export and run the game.

 

I'm sorry too, I had some thing like that wih IK CCD, not IK Limb, when number of bones is set more than 1 (for example , depending on the number of bones and othe IKs position), the nearest IKs may not work.

 

Thank you so much, that worked! The dog runs fine now, after I applied an IKGroup component to the GameObject that contains the IK's so that the IK's are listed in order from high to low in its' list. I Will make a note about adding an IK Group component whenever there are 2 or more IK's chained. This forum makes me happy and more confident with working with Unity! Any resources for related tutorials are greatly appreciated - I have seen Sergio's stuff on youtube, and the latest webinar on Anima 2D, but it seems that specialized tutorials for anima 2d are scarce.

 

Hi everyone! Is there a possibility to load a pose not in inspector by clicking the button "load", but from the script (something like PoseManager.LoadPose(myPose))?

 

can we apply custom shaders to Anima2D sprite mesh ? .. if so can any one direct me how to do it ? .. thx

 

Hi, I figured out how to do that. I just took out the Editor Load Pose Script and turned it into a regular script. Put the Attached Script into Assets/Anima2D/Scripts. To Call the function use

Code (CSharp):

1. Anima2D.PoseUtilsRegular.LoadPoseRegular(MyPose, Puppet.transform);

And an example to load from a resources folder:

Code (CSharp):

1. Anima2D.Pose MyPose = Resources.Load("Poses/"+PoseName) as Anima2D.Pose;  
2.         Anima2D.PoseUtilsRegular.LoadPoseRegular(MyPose, CurrentCharacter[0].transform);

 

Wow, thanks, @therockswell!

 

I never thought of doing this. Very handy, especially fun for letting the user take a screenshot of a character in a pose.

 

Hello,

We're using an external texture packer for our atlases (TexturePacker) and everything works fine until we modify our atlas. After modifying the atlas some of the sprites have moved and our spriteMeshs are still skinned at the previous positions of the sprites. So the character appears with wrong texture coordinates :-( So we have to recreate all meshes if we change our atlas which is very bad.
I searched a lot on this and everyone seems to use Unity built-in sprite packer for this. I am a bit surprised. So I'm wondering, do we absolutely need to use Unity built-in sprite packer in order to be able to modify our sprites our is there a functionality I missed that could move the skinned spritesMesh to the new positions of the sprites in the atlas?

Thanks for the hard work on the plugin, we love what we can make with Anima2d!

 

I'm currently having the exact same problem. Do you have found any solution with TexturePacker?

 

So far no, I had put this on hold to wait if I can have an answer here...

 

Yeah like so. Also posted the problem on TexturePacker thread, see if someone has a solution:
https://forum.unity.com/threads/tex...ite-mesh-optimizer.367738/page-2#post-3452917

 

@Sergi_Valls do you have any answer about this?

Thanks!

 

I haven't tried the new animation package, I will! The first reason we still use texturepacker is because we used it for years, before Unity even had a texture packing solution. The second reason is to keep control over our textures. With this we can load/unload the texture we need on demand. With Unity's texture packing solution we do not have control if it's loaded or not. Controlling that will help us keep memory usage low.
Thank you for your answer!

 

I use texture packer too and I have same problem.

 

Will it be possible to import Anima2D SpriteMeshes and Bones weights into Unity 2018.1 new 2D Animation system ?

What will be with Anima 2D after release of 2018.1 2D Animation system ?

 

Hello everyone,

I am having an issue when I use the SpriteMeshEditor. After I have made my changes, whether that be creating the mesh or binding bones, anything really, and hitting apply I get an InvalidOperationException error. I tried copying the file placement of the examples, using atlases, changing sprite import settings and even loaded the TREX into the SpriteMeshEditor, hit apply, same error. Any guidance or advice on this would be very helpful.

Thanks all for your time

Thank you so much for the reply!

I imported the asset using the built-in import feature and have not touched the folder hierarchy. As it stands I have still have the three anima folders in the default location they imported in to (Anima2d, Editor default res, gizmos all in main project folder).

 

Hey guys

I did a small workshop on unity anima2d and made a small tutorial as well (with some typos) thought Id share.

Tutorial: https://drive.google.com/open?id=1A793oqYBox4xWve-siaDZQsmnBtlaGXG

Assets and stuff used in tutorial: https://drive.google.com/open?id=1p6dLnOUMw6Qts-QDdzL1IWof1QnESM9s

Cheers!

 

In my game there is 200+ IK CCDC with 5 bones attached to each one. I see a performance hit due to the IK calculations. 50% of all game CPU resources go to IK late update calculations. After some research to how to speed up the game, I found that even if IK is doing nothing (not moving) it take the CPU resources. In my game 50% of time IK transform not moving. So I made a method that detects it and disable / enable IK behavior when needed. This gave me 30% performance boost in my game. Maybe this info will help to someone.

My question, is it possible to optimize IK calculations to run faster, and is it possible not to take CPU resources when there is no movement of IK?

Thanks a lot.

 

I just updated to the 2018.2.0b1 beta.

I know get this error:
Channel missing from vertex stream layout
UnityEngine.Mesh:set_uv(Vector2[])
Anima2D.SpriteMeshInstance:UpdateCurrentMesh() (at Assets/Anima2D/Scripts/SpriteMeshInstance.cs:307)
Anima2D.SpriteMeshInstance:Awake() (at Assets/Anima2D/Scripts/SpriteMeshInstance.cs:274)

Here is the line it doesn't like.:

Code (CSharp):

1. m_CurrentMesh.uv = m_InitialMesh.uv;

Any ideas?

 

Does anyone have the problem of having IK not moving limbs properly if the asset is rotated?

 

Somehow similar bug my other colleagues are experiencing right now. Anima2D animations works fine on my pc. But on my other colleagues' pc, the mesh doesn't show up and the only ones showing up are the bones, probably because of this error. We're using unity 2018.1.0b9. We thought the download through cloud is the problem so I zipped the project folder and sent it to them but they experience just the same bug. Any similar experience with this and a possible fix?

UPDATE:

I think what I did wrong is that I didn't use the "Export to Prefab" functionality from Anima2D. I just dragged the gameobjects to the project window, which is the usual thing we would do if we're making a prefab. Export to Prefab removed the bones from the gameobjects but atleast the animations are now working on my colleagues' pc/laptop. I just want to know now if this is the intended behavior. Aside from these what shortcut keys(windows) can I use in order to make rigging easier/faster, (for example: creating a bone) is there any documentaion/links for those? Thanks for the tool.

 

Bug: During slicing changing tessellation from 0 to 1 will make sprite invisible if bones were previously bounded

 

Hello!
We're using Anima2D for our trees swaying in the wind. I've been messing around with an editor script which randomises the hue of sprites within a certain range. Gives a nice effect to nature without having to colour each bit by hand. Unfortunately it doesn't seem to work with SpriteMeshInstance. It works in editor but, unlike the normal SpriteRenderer objects, this new colour change is removed on play mode. Is there another step I need for this to work? I've posted the code here, (with the functional spriteRenderer code commented out.)

Hope that was clear. Thanks for your time!

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEditor;
5.  
6. [CustomEditor(typeof (SetRandomHue)),CanEditMultipleObjects]
7. public class RandomHueEditor : Editor {
8.  
9.     public override void OnInspectorGUI()
10.     {
11.         DrawDefaultInspector();
12.         serializedObject.Update();
13.         if (GUILayout.Button("Set Random Hue"))
14.         {
15.             foreach (SetRandomHue set in targets)
16.             {
17.                 set.SetColour();
18.             }
19.         }
20.         serializedObject.ApplyModifiedProperties();
21.     }
22.  
23. }

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using Anima2D;
5.  
6.  
7. [System.Serializable]
8. public class SetRandomHue : MonoBehaviour
9. {
10.     [SerializeField]
11.     float hueMin; //.14f
12.     [SerializeField]
13.     float hueMax; //.333f
14.  
15.     public void SetColour()
16.     {
17.         float hue, saturation, value;
18.         Color.RGBToHSV(GetComponent<SpriteMeshInstance>().color, out hue, out saturation, out value);
19.         GetComponent<SpriteMeshInstance>().color = Random.ColorHSV(hueMin, hueMax, .8f, .9f, .9f, .9f);
20.        // Color.RGBToHSV(GetComponent<SpriteRenderer>().color, out hue, out saturation, out value);
21.        // GetComponent<SpriteRenderer>().color = Random.ColorHSV(hueMin, hueMax, .8f, .9f, .9f, .9f);
22.     }
23.  
24. }

 

Is there a way to change the size of IK handles? I want to drecrease the size of the blue IK handles.

 

Thanks Sergi.

At what point do you think it's worth switching over to the new 2D bone/animation system?

 

Is there any news on draw call optimization?

Best Regards,

 

Hi @Sergi_Valls,

I've been playing around with Anima2D for a couple of hours now, and it seems to be quite broken in Unity2018.1 :

- open UnityChan scene
- select "dress" SpriteMeshInstance
- in the SpriteMesh Editor, change tesselation to any value and click apply
- bug1: it removes the tesselation for some reason (only has outline vertexes now)
- click "auto" in the weighting panel, and click Apply in the top bar
- bug2 : dress spritemesh is now invisible

I've had some other issues as well with my own sprites... Images disappearing, getting AABB errors, etc. I have yet to succeed in setting up a complete character, but I can't rule out user error yet... The bugs above are easy to reproduce though, and I don't think that behaviour is intended, but it's always possible that I'm missing something.

Thanks!

 

Thanks, that did the trick! Though I don't understand why it can't have a hole. It might be a good idea to have it give me some kind of warning hinting me at what's going wrong.


Also, I just set up a character mostly successfully, but it keeps spamming "Assertion failed: Invalid AABB a" in the log. Any ideas as to what can be causing this? It might be more user error, but it's not giving me much clues as to what I'm doing wrong.

Thanks!
