Move the "head.Rotation=120.0f;" line after your debug log statements. If the head is null it crashes the script there and thus it cannot continue to log your statements.

Which line is line 24? Is skeleton null? Is skeleton.skeleton null?

The crash should tell you why. What about my other 2 questions? One of those two are null. Not sure why.

Hmm. Take a look at tk2dSpineSkeleton.cs. If Update is called and it has a skeletonData, then it calls Initialize which creates the skeleton. So, I assume your code is running before Update is called. Maybe you need to change the order of your components? Is your tk2dSpineboy component after your tk2dSpineSkeleton component?

Hey Nate I ran into the same problem, you were right It was checking before it was initialized. I went ahead and did the following

using UnityEngine;
using System.Collections;
using Spine;

public class tk2dSpineboy : MonoBehaviour {
	
private tk2dSpineSkeleton skeleton;
Bone head;
bool checker=false;


void Start() {
	skeleton = GetComponent<tk2dSpineSkeleton>();
	Invoke("caller",.10f);
}


void Update() {
	
	if(checker){	
	head.Rotation=(head.Rotation+10.0f);
	skeleton.skeleton.UpdateWorldTransform();
	}	
   	
	
	if(skeleton.loop) return;
	
	if(skeleton.state.Time >= skeleton.state.Animation.Duration - 0.25) {
		skeleton.animationName = "walk";
		skeleton.loop = true;
	}
}

void OnMouseDown() {
	skeleton.animationName = "jump";
	skeleton.loop = false;
}


void caller(){
head = skeleton.skeleton.FindBone("head");
checker=true;
}

}

For some reason though the head still does not rotate. Am I doing something wrong here? thanks for the help.

If the tk2dSpineSkeleton is applying an animation that keys the head, then that will overwrite your changes to the head.

So I am still trying to get this work , I just updated to the latest run time, and in the LateUpdate() function I am doing the following (everything else is virtually identical to the above code)

skeleton.state.Animation.Apply(skeleton.skeleton,skeleton.state.Time,true);
head.Rotation=(head.Rotation+1.0f);
skeleton.skeleton.UpdateWorldTransform();

The comment above the Apply function in the Animation script says :
/** Poses the skeleton at the specified time for this animation. */
Still there is no movement. @Nate what is the proper way to rotate the head during an animation? Thanks.

I'm also using 2d toolkit. Try calling FindBone on every update to see if that fixes the issue. I was having problems storing a reference to bones as well.

Maybe during the animation that bone data is getting cleaned up causing the reference to go bad?

Also, there is a setup pose Head bone, and then there's the bones that are changed during the animation. Maybe we should be trying to get a reference to the setup pose one. This diagram might help:

Edit: I might be confusing Bones with BoneData though. There might only be just one Bone, BoneData for the setup pose, and then BoneData used during the animation.

Looked into it a bit more. My problem came from the tk2dSpineSkeleton calling the Unity Start() function (which creates the actual spine Skeleton object) AFTER the Start function in my script that calls FindBone on the head.

Still would be worth calling FindBone on every update just to see if it's related to a bad reference.

I've checked the head and it's not null, and the rotation does change during the walk animation sequence (it is keyed to do so during the animation). My thought process was that I would rotate the head, update the skeleton based on the rotation and than during the next update pass, the animation would take into account the modification to the skeleton. Somewhere in this process I made an error. I don't think that this requires using the Mix() function (I tried that to). Oh well enough for tonight, will be back at it tomorrow :time:

M.O. a écrit

That code is ok. I assume head is a Bone. I assume you have the head keyed, so what will happen is each frame in your game, the SkeletonAnimation will update, pose the skeleton using the animation which will set the head rotation, then your code runs which adds 1 to the head rotation. So you will always get the head rotation the animation sets, plus 1. You could store a rotation value in your class and add to it each frame if you want the head to spin around. Try setting the head rotation to a fixed value, like 45.

Bone is the skeleton's current pose. You can also get the BoneData, which is the setup pose. Animations are relative to the setup pose, so you can change the BoneData with code similar to what you posted and the head will spin around. Make sense?

Thanks Nate!
So for anyone that runs into the same problem, for some reason setting the bone.rotation to any number even high numbers, ex. 90.0f didn't do anything. setting the boneData.Rotation allowed me to rotate the head!
