我这个问题比较特殊,我也没有找到具体哪个脚本的问题,但是可以知道的是,我把模型删除了,然后BoneFollower这个脚本在LateUpdate更新的时候调用了transform组件
if (skeletonTransformIsParent) {
// Recommended setup: Use local transform properties if Spine GameObject is the immediate parent
thisTransform.localPosition = new Vector3(followXYPosition ? bone.AppliedPose.WorldX : thisTransform.localPosition.x,
followXYPosition ? bone.AppliedPose.WorldY : thisTransform.localPosition.y,
followZPosition ? 0f : thisTransform.localPosition.z);
if (followBoneRotation) {
float halfRotation = Mathf.Atan2(bone.AppliedPose.C, bone.AppliedPose.A) * 0.5f;
if (followLocalScale && bone.AppliedPose.ScaleX < 0) // Negate rotation from negative scaleX. Don't use negative determinant. local scaleY doesn't factor into used rotation.
halfRotation += Mathf.PI * 0.5f;
if (followParentWorldScale && scaleSignX < 0)
halfRotation += Mathf.PI * 0.5f;
Quaternion q = default(Quaternion);
q.z = Mathf.Sin(halfRotation);
q.w = Mathf.Cos(halfRotation);
thisTransform.localRotation = q;
}
} else {
if (!skeletonTransform) return; //新增的语句,加入后可解决这个报错,希望你们也进行一个预判,避免错误,让脚本更加健壮
// For special cases: Use transform world properties if transform relationship is complicated
Vector3 targetWorldPosition = skeletonTransform.TransformPoint(new Vector3(bone.AppliedPose.WorldX, bone.AppliedPose.WorldY, 0f));
if (!followZPosition) targetWorldPosition.z = thisTransform.position.z;
if (!followXYPosition) {
targetWorldPosition.x = thisTransform.position.x;
targetWorldPosition.y = thisTransform.position.y;
}
Vector3 skeletonLossyScale = skeletonTransform.lossyScale;
Transform transformParent = thisTransform.parent;
Vector3 parentLossyScale = transformParent != null ? transformParent.lossyScale : Vector3.one;
if (followBoneRotation) {
float boneWorldRotation = bone.AppliedPose.WorldRotationX;
if ((skeletonLossyScale.x * skeletonLossyScale.y) < 0)
boneWorldRotation = -boneWorldRotation;
if (followSkeletonFlip || maintainedAxisOrientation == AxisOrientation.XAxis) {
if ((skeletonLossyScale.x * parentLossyScale.x < 0))
boneWorldRotation += 180f;
} else {
if ((skeletonLossyScale.y * parentLossyScale.y < 0))
boneWorldRotation += 180f;
}
if (followParentWorldScale && scaleSignX < 0)
boneWorldRotation += 180f;
Vector3 worldRotation = skeletonTransform.rotation.eulerAngles;
if (followLocalScale && bone.AppliedPose.ScaleX < 0) boneWorldRotation += 180f;
thisTransform.SetPositionAndRotation(targetWorldPosition, Quaternion.Euler(worldRotation.x, worldRotation.y, worldRotation.z + boneWorldRotation));
} else {
thisTransform.position = targetWorldPosition;
}
additionalFlipScale = Mathf.Sign(skeletonLossyScale.x * parentLossyScale.x
* skeletonLossyScale.y * parentLossyScale.y);
}
