[DEPRECATED] Anima2D - Advanced 2D Skeletal Animation Plugin

Hi! I wanted to share small fix for character X scale. Did not know if anyone fixed/occurred it before.

When you will try to turn unity chan from samples to look left, with scaleX = -1 it will broke it like this:



To look it like this:


You need to add scale multipler into SpringBone.UpdateSpring.

right after line:

//stiffness
Vector3 force = trs.rotation * (Vector3.right * stiffnessForce) / sqrDt;

add:

force *= scaleX;

You can pass scaleX into UpdateSpring:

public void UpdateSpring (float scaleX)

You can pass this parametr from SpringManager:

springBones .UpdateSpring (m_scaleX);

And you can get that scale from Transform you need:

public Transform m_followThisTransformScaleX;

if(m_followThisTransformScaleX != null)
{
m_scaleX = Mathf.Sign(m_followThisTransformScaleX.transform.localScale.x);
}

Hope it will help someone!

 

Hi Sergi, sorry I ran into another issue today.

The character I'm working on looks fine on my computer, but looks messed up on others. An image for comparison


It looks like each sprite mesh has all the sprites under the same packing tag crammed into it. Also the number of sprite meshes affected vary on different computers, for example, on another computer, only the legs are affected

They also get some errors




Thanks in advance!

 

Hey there! First of all, yes, we removed the packing tag on my colleague's files and it worked immediately. We then added the tag back and it continued to work. We then checked git and the changelog shows that the sprite meta files were updated with new iOS import settings, which makes sense, because I didn't install an iOS build module, while my colleague did. So did my lack of iOS import settings mess up the meta file for the other people who did?

 

Any update on free-form deformation?
Right now is doing any king of mesh deformation? Because when the T-rex moves his head up and down it seems to be some stretching on the neck, is this right?

 

Hi Sergi, thanks for the reply!

After we 'fixed' the issue by removing and adding the packing tag last time, the problem reappeared on another computer, so we deleted the atlas cache and allowed Unity to recreate, but for some reason it didn't work.

We removed the tag again, and the problem was gone, but this time after adding the tag back it broke again. Only after giving the sprites a different tag resolve the issue.

So we're still somewhat unsure how and when the meta updates, and how we could consistently force updates.

 

Hello Sergi, just an update on the question

You mentioned that the userData property is updated when there are changes in the spritemesh, however our UnityChan atlas is frequently shown to have updated userData even though we've never touched it, which adds to the confusion. Could this be related to our problem?

Thanks again.

 

Greetings,
I'm trying to bake some animations but i have the follow error inside the unity editor:

I work on linux with the latest unity build. 5.6.0xf3

Thank s for this great Asset

 

Hi, do you think i should downgrade to unity 5.5? I can t wait too long.. I noticed also that onion skin doesn t work anymore.

 

Hi everyone, i'm posting here because i'm making some characters with Anima2d for an upcoming Game, I made and animated my character without trouble, and it works when I press the play button, but I get the following errors. I must have done something wrong because these are no errors related to unityChan, only to my character.
And the strange thing is that I get these errors even if my prefab is not into my scene !
I'm curently working on Unity 5.6, and reimported Anima2d about 3 hours ago.

Thank you all for your help !

 

Hi, and thank you for your help, as you requested i'm sending you a package with my animated character in the middle of an empty scene.

And I also had some errors using the "mesh combiner", maybe I used it the wrong way ? If you could quickly explain me how to use it properly this would be awesome !
Don't hesitate if ou have any question

 

Hi, I don't know if it's just me but while animating when move a control of a bone and undo the character become messed up. and some time after undoing the key was removed but when i play the action is still there. but all of the problems will go away after restarting unity.

I'm using Unity 5.6.0f3
I've already updated to the latest Anima 2d from asset store.

Thanks.

 

Hi, any way to get a part flipped? I mean I'm trying to get a leg that uses symetry, but I can't get it to work, any time I reasign the bones the sprite flips as it was in the original, and bones don't work with Y scale to -1.

Is there a way to work with sysmetry?

 

I read that Spring bone is not a feature of Anima2D in an old post.
But...anyone knows where to find doc about it? How to use Spring collider or how to collide the spring bones?

thanks

 

We found that when using "Skinned Mesh Combiner" scripts , all sprites lost it's color tint information. Is there any way that we can use "Skinned Mesh Combiner" without losing the color tint info and save drawcalls ?

 

Hi sergi:
i am using unity5.6 and i have a character using skinned mesh combiner script, but my sprites sorting order went all wrong. it turned out that the order became the list order of Sprite Mesh Instances.
is this a bug or it is designed like this?

 

Any chance for FFD animation tool to Anima in near future ? I am more than sure that everyone will agree that is last piece we need ito bring that plugin as ultimate animation tool

 

Hi, just to report, auto calculate weight doesn t seems working on unity 5.6.0xf3 linux release. No errors when the button is clicked. Any chance to get it working or fix it?

thanks.

Edit: I didnt see the error.

DllNotFoundException: Anima2D

I have the same problem now , any way to fix that or i did something wrong ?

 

Hi,
Love Anima2D so far! But just before I got to animate my finished rig this problem showed up. I'm using Unity 5.6.
The IK limb works fine on 3 of 4 legs. On one of them it still works fine, but not in play mode. Have tried to create new ones but the same happens. Please see attached images. Excact same setup where the last image is in Play mode the toe tips down. Thanks for any help on this!

 

I solved it myself Creating the IK limbs from TOE and last the LEG did the trick. Creating IK limbs from LEG and then TOE was not working

 

When freezing the game using Time.Timescale = 0, Anima2D spring bone positions go back to default.
Is there a slightest chance it will be solved somehow?
Cheers.

 

Hello,

I have a 2d character that has nested child objects for the torso, upper arm, lower arm and gun. I placed a transform (spawn point) at the tip of the gun which I could see positions correctly when I animate with mecanim using Anima2D. The problem shows itself when I debug.draw a line from the spawn point towards the mouse. It seems intermittently jumping on 2 places (correct location and another). I think it's a bug (nested deep) as it works if I place the transform 2 parent bones up.

Does anyone have an idea how to fix this?

Thanks in advance Solo

 

Okay, the pic below shows the hierarchy, you'll see the "FirePosition" transform as a child of the RLA Bone.


This is the script attached to the FirePosition which is used to draw a line from the FirePosition & mouse:

Vector2 firePointPosition = transform.position;

Debug.DrawLine(firePointPosition, mousePos);


I only use update to find out if the fire button is triggered, which uses the script above.

The video shows the FirePosition in focus. You can see, it's not the same position as where the line starts.

I use IK for the hands and feet.

That did it! Lol.
Thanks for your help.

BTW, Anima2D is such an awesome animation tool!

 

Hi! Is there a way to assign different sprites at runtime? For example, I have a character with open eyes and closed eyes sprites. Can I replace each other at runtime using Sprite Mesh method? I just don't understand how to do that. If you try to replace the mesh in Sprite Mesh Instance, then it will break all the bones. Is there a way to do so?

 

Hi! Recently I've discovered a very weird bug:

In animation mode IK CCD2d works just fine. But when I hit Play - some mess happens. I can fix it with switch on/off current IK, but it's kinda annoying to do all the time. It also helps to bake an animation - but sometimes I need an original one.

Is there a reason why it happens? Can it be fixed in proper way?

 

Thank you very much.

 

Hi！
I have a preblem when I use the tool.
sorry,my english is bad!
I make an EditorWindow for myself.Inside I have a TextFiled,When I Input a word beginwith 'L',It's not compatible with your tool.
I can not continue to input any words.
It is Immediately stop,and I can only type in one char "L",
so can you explain why?

 

Code (CSharp):

1.  EditorGUILayout.BeginVertical();
2.                 this.scriptName = EditorGUILayout.TextField("脚本名字", this.scriptName);
3.                 this.uiPrefab = EditorGUILayout.ObjectField("UI预制物", uiPrefab, typeof(UnityEngine.Object), true);
4.                 this.bIsResident = EditorGUILayout.Toggle("是否常驻内存", this.bIsResident);
5.                 EditorGUILayout.Separator();

when I input some char into the TextField, It forces me not to type in and finish.So I can only input 'l'.

 

Just Like this picture.I can't input any more char When the word beginwith 'l'.

 

Thanks!

 

Hi,
any chance to replace the sprite in previously created and binded mesh?
Or possibly to copy the whole mesh to another sprite?
The main point that I want to reach is to have two absolutely identically working meshes with the different sprites (parts of multiple sprite).

 

My codes is packed into DLL.so I send you a unitypackage but you can't see the codes.
I send you a gif about this case.
When I wirte a word beginwith 'l' or 'Log',It forced interrupt input and continue execution my code.So it have some errors.
The key is why I wirte a word beginwith 'l' and 'Log',It would forced interrupt.

 

Hi Sergi - I'm trying to create some foreshortening (eg when an arm gets smaller when pointing toward the camera) by changing the bone length. Unfortunately changes in bone length don't scale the SpriteMesh. Do you have any ideas on how I might approach this? Scaling X doesn't work because it messes with all the children, which may be rotated etc.

I'm comfortable getting into the Anima2D code to make changes if you have any suggestions. On that point, is there a repo I can suggest fixes or improvements I make? (eg Bone2D.color set { color = color; } I've fixed to set { color = value; }). I'm building solutions off of Anima2D and would love some insight into future changes, like why is m_Child commented as //Deprecated?
