@Mitch That didn't change anything, unfortunately. I have disabled and even removed my second (upper body) layer in the Animator, but the issues persist within the Base Layer.

I just noticed the keys that are dropped are only those that attach an image to a slot. All Scale/Rotate/Translate keyframes are applied just fine.

Sure, just PM me your email address!

This looks amazing! Will these features be included in the tk2d runtime aswell?

It worked, thanks

Would love to see this in the official runtime tho, no pressure

Hey! First post here :-)

Thanks Mitch for creating the SkeletonAnimator. I just started using Spine (it's been in my todo list forever) with Unity 5. Against all advice, I'm using mecanim since I'm familiar with the kind of state machines you can create with that (and I can't be arsed to create my own State Machine solution from scratch right now). Your SkeletonAnimator is working like a charm! I can "navigate" the state machine and see the animation change to what I created on Spine. Yay!

My next step is to use events. You said they have the same limitation as when you baked the animation using the previous system (SkeletonAnimation?). That makes me happy, because it seems to imply that I can use Spine events with mecanim in Unity 5. The problem is that I don't see where to hook my delegate to listen for events. I've been searching the C# and Unity runtimes but it only seems to exist hooks in AnimationState (old system). The docs also point to AnimationState. Can we listen to Spine events when using mecanim?

He means it's using Unity's Animation events, not Spine-C#'s events.
SkeletonAnimator (and Mecanim) don't touch Spine.AnimationState (where the Spine event delegates live).
SkeletonAnimator also doesn't interface with Spine.EventTimeline.

I'm actually not sure where the events are defined for SkeletonAnimator. I guess in the "dummy" animation clips?

Yeah, they're in the clips (you can inspect them with the Animation window) - and since they're Unity events, they're actually SendMessage-style and calling the function with the same name as the event: http://docs.unity3d.com/Manual/animedit ... vents.html

Hi Mitch,

I'm brand new to Spine, so please forgive any stupidity in this post. It looks like I've picked up your latest with the unity package runtime, so I can use the create animation controller action you outlined above. But I'm not really understanding how to configure it, or even the intention here

When I instantiate the controller via Spine->InstantiateMecanim, it looks like it generates a mecanim anim controller that flattens all animations to interface with a single GO: "Game Object.Dummy". How is this configured? I see that the SkeletonData seems to retain linkage to the animator once this is done, which I assume is to aid in iteration. But when I generate a new SkeletonAnimation via Spine->InstantiateSkeletonAnim, it doesn't include the new Animation Controller. When I connect the Spine generated animation controller, it complains that it can't find the Dummy object. Am I missing something fundamental here?

Also, just so I'm clear, this is intended as a "lighter" approach to allowing mecanims to control animation state without incurring (most of) the functionality hits of baking it completely into Unity. Am I completely mistaken here? I hope not, because it seems like exactly what I want.

Thanks!

Jeremy

Thanks for the speedy response

I was out Friday, but am looking at this again today.

Aha

I think I get it now. I was sort of stuck on what option #2 was actually doing, but if the Dummy object is only for timing purposes, that makes sense. Just so I get a sense of workflow, how brittle is that animator/animation set when iterating in Unity? As in, if I put some custom function call hooks within an individual animation or substates/conditionals within the animator, will that all need to be redone if I update something like an animation length in the Spine editor (requiring a rebuild from the json upon reimport)?

So far so good though, I have gotten it to work with a custom mecanim state machine, thanks again for the help!

Okay, that's what I was hoping

thanks Mitch!

I've got most of it working, but I've moved onto events and had another question. It seems that the general technique for managing events is interfacing via the AnimationState, but I don't know how to query for that when using a SkeletonAnimator.

I am able to receive Spine events as Unity/mecanim style events on the mecanim timeline

though, admittedly, assuming the string name of the event as a hardcoded function call seems a little bizarre, perhaps they should at least be prefixed with "SpineEvent_" for clarity/name-collision safety? Or maybe use something more similar to the way you do your Spine attributes, with a [SpineStringEvent("EventName", "FuncMapping")] style approach?

Anyways, how would you go about getting the Complete/End generic events without AnimationState? Or, maybe a better question: how would you get the AnimationState from SkeletonAnimator?

Also

unrelated: it seems that if you have an animation without any textures in it (a guide animation), the Unity plugin will fail to produce any of the skeleton data exports from the json. Putting a junk texture in there seems to fix the problem, probably just a minor bug.

Thanks again, this has been very helpful!

Jeremy

Okay, I'll use unity graph behaviors for the complete (OnStateEnter) and end (OnStateExit) events.

So I'm seeing a lot of weird twitchy graphical behaviors (such as flipping on the x-axis in the middle of an animation) that I don't see when using a standard skeleton animation. Is there something that I may have misconfigured? Or maybe you have an updated build with some bug fixes?

Oops

nevermind about the twitchy behavior, it was something I had misconfigured. I believe this was caused when I mistakenly had some blending in one of my transitions, causing some very strange results.

Thanks ~ things are looking good with this integration, I like being able to use u5's state machines in my project!

Hi jeremy,

Can you go a bit into details what the problem was and how you solved it?
I seem to have some twitchy behaviors too (flipping X axis). I can indeed pinpoint it to having blending in the mecanim setup.
However, I actually DO want to have blending enabled when switching between animations, so I'm wondering if you managed to somehow have them without the glitches?

I basically turned blending off in mecanim for now to fix any animation weirdness. I'm still not entirely sure what the dummy anims are doing and if blending should actually work via mecanim. I assume the blending could be handled by the Spine animation engine, but I'm not sure if mecanim is able to feed Spine enough information for it to operate properly

this was noted earlier as an issue with mecanim integration in u4.x, maybe u5 solved the problem. Obviously, Mitch would have a lot greater insight here, and maybe lay out some best practices.
