spine-unity transform player to root position on last frame of animation

fshakhverdiyev

My player have climbing animation. And climbing animation contains "root" bone movement. I want to translate my player to "root" bone position on last frame of animation. But i have some problem : If i try keep last "root" bone position on some variable and after translate player to here and restore "root" bone position it doesnt work :
Code snippet : (This happened on animation end)
Vector3 position = SkeletonAnimation.Skeleton.RootBone.GetWorldPosition(Transform); Transform.position = SkeletonAnimation.Skeleton.RootBone.GetWorldPosition(Transform); SkeletonAnimation.Skeleton.RootBone.WorldX = position.x; SkeletonAnimation.Skeleton.RootBone.WorldY = position.y;

You can see in screen record : After translate player to "root" bone, "root" bone doesnt restore self position. Maybe it cant because bone mode is Follow. But i cant do this in anyway.

fshakhverdiyev In general, it is recommended to use the SkeletonRootMotion component if you want to apply root motion to your skeleton. Are there any conditions you have to write code without using this component?

fshakhverdiyev

Spinebot I try this version but doesnt solve issue. I dont use any other compenent just using SkeletonAnimation and Player script. Player script change player position to root bone position on end of climbing animation and restore root bone position. I notice that root bone position still same position

Misaki

fshakhverdiyev Sorry, I removed Spinebot's answer to avoid confusion.

Misaki I can use this component but i have tone of animations without root motion. If i enable for some specific case i think this maybe cause some issues. Isnt it ? For example : Walk, Run, Jump etc. doesnt need SkeletonRootMotion on my case. What do you recommend ?

fshakhverdiyev

Misaki And when i disable root motion, root bone behave like same. And same issue coming again. I just want to translate my player to root bone position and keep root bone where its are. If my solution merhod is wrong please give me advice for achieving that. Thanks!

Misaki

fshakhverdiyev It is a good idea to have a track for the animation to which the root motion needs to be applied and specify the track number in the Animation Tracks of the SkeletonRootMotion component.

The SkeletonRootMotion changes the position of the GameObject not at the end of the animation, but at any time, so there should be no problem with the GameObject returning to its original position if it is disabled in the middle of the animation.

Misaki This help me a lot! Thanks 😃

Misaki But i cant handle opposite direction. Am i on wrong way for create player like this ?

You can see : CLimb to right side work perfectly but not left. Because root bone position still translate to same direction. What is good way create simple Climbing like this ?

@fshakhverdiyev How did you mirror the skeleton to chieve the direction flip? In general the SkeletonRootMotion component should work automatically with flipped x direction movement.

fshakhverdiyev

Harald I fix the issue from zero. I remove root motion completely and remove root key frames from animation. I manually update my Rigidbody velocity in script. I think this is maintainable, predictable and extendable. If your have any advice for me. Please let me know. Thanks! (Flip my character with root bone ScaleX)

fshakhverdiyev If your have any advice for me. Please let me know. Thanks! (Flip my character with root bone ScaleX)

Are you flipping the same root bone that you're using as Root Bone for the RootMotion component? If so, that sounds somewhat problematic to me. I'm not quite sure yet if this shall be supported or whether it poses a theoretical problem.

Please consider flipping via setting Skeleton.ScaleXor via flipping the GameObject's Transform Scale X value for now.

That's good to hear, thanks for letting us know.

Harald Hi again. On my case : ScaleX set -1 for root bone. And RootMotion component applied for rootBone but root motion applied for just 1 direction. For example : If Root going to 1.9x 1y for ScaleX = 1 same for ScaleX = -1. But i expected -1.9x and 1y. How can i achieve that ? Is it possible ?

fshakhverdiyev

Harald Skeleton.ScaleX works fine thanks

Harald

fshakhverdiyev Hi again. On my case : ScaleX set -1 for root bone. And RootMotion component applied for rootBone

By the above sentence, do you mean you have the following hierarchy?

root       // you scale that -1 and 1
- rootBone // this is your bone assigned at the SkeletonRootMotion component
-- hip and other skeleton bones

fshakhverdiyev @Misaki @Harald can you asist please ?

Please note that during weekends replies may take until Monday.

fshakhverdiyev Harald Skeleton.ScaleX works fine thanks

Glad to hear you've got it worked out! Thanks for letting us know.

fshakhverdiyev

@Misaki @Harald can you asist please ?

Harald

@fshakhverdiyev We've just tested the above hierarchy, which works as intended on our end:

root       // you scale that -1 and 1
- rootBone // this is your bone assigned at the SkeletonRootMotion component
-- hip and other skeleton bones

So unfortunately we could not yet reproduce any issue on our end. Could you please describe your bone hierarchy and scaling setup?
