I'm trying to adapt the SpineboyTargetController from the "Getting Started" example to use SkeletonMecanim instead of SkeletonAnimation. The original script gets the mouse position and sets a "Shoot target" bone at that position.
However I can't figure out how to get a Bone from a SkeletonMecanim, to then be able to change it's transform, and also get the transform of the animation.
What I tried skeletonMecanim.skeletonDataAsset.GetAnimationStateData().skeletonData.FindBone(boneName); returns a BoneData object, and not a Bone.
Also i can't find the equivalent of skeletonAnimation.transform in a SkeletonMecanim.
Here's the original code:
public class SpineboyTargetController : MonoBehaviour {
public SkeletonAnimation skeletonAnimation;
[SpineBone(dataField:"skeletonAnimation")]
public string boneName;
public new Camera camera;
Bone bone;
void OnValidate () {
if (skeletonAnimation == null) skeletonAnimation = GetComponent<SkeletonAnimation>();
}
void Start () {
bone = skeletonAnimation.Skeleton.FindBone(boneName);
}
void Update () {
var mousePosition = Input.mousePosition;
var worldMousePosition = camera.ScreenToWorldPoint(mousePosition);
var skeletonSpacePoint = skeletonAnimation.transform.InverseTransformPoint(worldMousePosition);
skeletonSpacePoint.x *= skeletonAnimation.Skeleton.ScaleX;
skeletonSpacePoint.y *= skeletonAnimation.Skeleton.ScaleY;
bone.SetLocalPosition(skeletonSpacePoint);
}
}
Here's my code. I've marked my issues with "ISSUE".
public class SpineBoneTargetController : MonoBehaviour {
public SkeletonMecanim skeletonMecanim;
[SpineBone(dataField:"skeletonMecanim")]
public string boneName;
public new Camera camera;
Bone bone;
void OnValidate () {
if (skeletonMecanim == null) skeletonMecanim = GetComponent<SkeletonMecanim>();
}
void Start () {
// Original code
//bone = skeletonAnimation.Skeleton.FindBone(boneName);
// ISSUE - I've tried this, but it returns a BoneData object
bone = skeletonMecanim.skeletonDataAsset.GetAnimationStateData().skeletonData.FindBone(boneName);
}
void Update () {
var mousePosition = Input.mousePosition;
var worldMousePosition = camera.ScreenToWorldPoint(mousePosition);
// ISSUE - How to get the transform of the current animation? (skeletonAnimation doesn't exist here)
var skeletonSpacePoint = skeletonAnimation.transform.InverseTransformPoint(worldMousePosition);
skeletonSpacePoint.x *= skeletonAnimation.Skeleton.ScaleX;
skeletonSpacePoint.y *= skeletonAnimation.Skeleton.ScaleY;
bone.SetLocalPosition(skeletonSpacePoint);
}
}
Thankful for any help! 🙂
