Animation Clips in Unity???

SoloChristian

I'm importing into Unity using 2D Toolkit. everything seem to be working except I can't seem to find the actual Animation Clips. Spine Import doesn't seem to create any. Having Animation clips would allow Much Easier usage of Spine with other systems.

Also if I make a Prefab with the imported character. The skeletal mesh and animations vanish on the Prefab unless it is actually dragged into a scene. Then they magically reappear.

A lot of the Spine runtimes are kind of semi-engine-agnostic.
This includes Spine-Unity, whose classes are mostly written in plain C# without using any extraneous library's classes. So it works with XNA/MonoGame, Unity and potentially other engines that run with .NET/Mono.

The Spine-Unity runtime is actually more like a bridge between UnityEngine functionality and Spine-C# functionality and mostly just handles engine-specific rendering (the use of components and the UnityEngine.MeshRenderer.)

The reason why it doesn't use UnityEngine.AnimationClip objects is because it uses Spine.Animation objects. This not only makes it easier for them to maintain Spine runtime's code but also gives it more control over how things are rendered, allowing features like free-form deformation, skinning, keyable draw order, etc to work.

The Spine.Animations are stored in the skeleton's json and deserialized at runtime into Spine.Animation objects, accessible through each SkeletonComponent/SkeletonAnimation's SkeletonData. Use SkeletonData's FindAnimation method to get references to them at runtume/loadtime.

Well Sadly some Real Documentation could be used then. Because I know Nothing of Json and the one example of spine boy switching to jump on mouse click really doesn't properly explain it.

You really don't need to touch the json. That's what the Spine Editor is for.

If you only need to play animations, you just need to call SetAnimation through the SkeletonAnimation component's AnimationState member.

What did you need anyway? Maybe some people here can help. Spine's API isn't that hard to use.

SoloChristian

Well to start with, I have the character successfully importing and I have it as a child to an Empty Game object that has a Rigid Body on it.

The game is a point and click where the character basically moves left or right. So I need to run the idle animation when holding still and the walk animation when moving. Adjust the speed of the Walk animation based on the rigid body's speed would be a bonus.

The second question that comes to mind is there a trick to flipping the animation. Cause I want him to be facing the direction he is moving. Wether it's Left or Right.

You can set the animation to walk or idle based on what the user is pressing. You can do it via code, by calling SkeletonAnimation SetAnimation. To flip the skeleton use "skeletonAnimation.skeleton.FlipX = true;".

SoloChristian

Here is the code I am using. The walk works but doesn't loop smoothly. The idle doesn't work.

using UnityEngine;
using System.Collections;
using Spine;
using System;

public class SpineAnimControls : MonoBehaviour {
	public SkeletonAnimation skeletonAnimation;

public Rigidbody MyRigid;

public Player MyPlayer;
public WhichWay MyMoving;

public void Start () {
	skeletonAnimation = GetComponent<SkeletonAnimation>();	
	skeletonAnimation.state.Event += new EventHandler<EventTriggeredArgs>(Event);
}

public void Event (object sender, EventTriggeredArgs e) {
	Debug.Log(e.TrackIndex + " " + skeletonAnimation.state.GetCurrent(e.TrackIndex) + ": event " + e.Event + ", " + e.Event.Int);
}

public void Update ()
{

	if(MyPlayer.activePath == null)
	{
		Debug.Log("Holding Still");
		MyMoving.MovingDude = false;
		skeletonAnimation.state.ClearTrack(1);
		skeletonAnimation.state.SetAnimation(0, "idle", true);
		skeletonAnimation.state.AddAnimation(0, "idle", true, 0);


	}
	else
	{
		Debug.Log("Moving !!!!");
		MyMoving.MovingDude = true;
		skeletonAnimation.state.AddAnimation(1, "walk", false, 1);
	}


}


}

Just use these to change the animation:

skeletonAnimation.state.SetAnimation(0, "idle", true);
skeletonAnimation.state.SetAnimation(0, "walk", true);

I thought the First parameter was the # of the Animation. So if you had 2 animations the first would be 0 and the second animation would be 1 Etc... Etc.. If not what is the first parameter for?

Also if someone could explain exactly what this code does. I just copied it from the spineboy example:

  public void Start () {
      skeletonAnimation = GetComponent<SkeletonAnimation>();   

      skeletonAnimation.state.Event += new EventHandler<EventTriggeredArgs>(Event);
   }
   

   public void Event (object sender, EventTriggeredArgs e) {
      Debug.Log(e.TrackIndex + " " + skeletonAnimation.state.GetCurrent(e.TrackIndex) + ": event " + e.Event + ", " + e.Event.Int);
   }

Thanks for Helping me out! 🙂

First number is the track. Use zero unless applying multiple animations each frame.

That code is old syntax. You can use:

state.Event += Event;
// ...
public void Event (object sender, EventTriggeredArgs e) {
   /// ...
}

It adds a listener to the "Event" event which calls the method named "Event" when an event happens.
