Shaky camera when follow the bone

arboooz

Hello Guys,

I want to make a Cutscene in Spine and use it in Unity.

To control the camera movement I created a rectangle which I scale and move over the background. Now, I exported everything to the Unity. I made the Camera to follow the location rectangle. It works, but the camera movement is a bit shaky. Also, when camera moves I can see the left border of my frame. More or less I can imagine why it happens but I have no idea how to fix it.

So far I have two ideas on how to implement it, but both doesn't work as I expect.

1) In camera script, in Update action, I read the position of the bone and I apply that to the Camera object.
2) I generated skeleton hierarchy and put my camera object there.

Please help! 🙂

So far I found that running this code in LateUpdate callback, seems to be a bit faster - the issue with seeing frame border is gone. Also animation seems to work a bit faster when I export my project as an Osx app. But If I export it my iOS device (iPhone 6) it is super shaky.

I'm not sure what you mean by "shaky". You could be describing anything. Mismatched order of updates. Spine's limited resolution curves.
Can you record a video of it with your phone? Or make a screen recording?

Well that makes sense because on iOS you're probably running 30fps.

Are you lerping your camera movement? I wouldn't ever expect anything to be smooth by simply setting the Camera pos to translate the bone in real time.

Try something like:

void LateUpdate()
{
        Vector2 newPos = followedBone.position;

    // Lerp the camera's position between it's current position and it's new position (change smooth to fit game needs)
    transform.position = Vector3.Lerp(transform.position, newPos, smooth * Time.deltaTime);
}
