Jittering when doing animations with PicaVoxel

Hi folks,

I'm currently prototyping, and I have a issue I cannot solve, or better - I don't know what's happening.

Have a look at this video, and the feets starting in 00:17:

Basically, I have some kind of jittering or glitch. Now, this is an animation made with MagicaVoxel, imported with PicaVoxel. PicaVoxel creates a mesh for every frame, and then displays them one after another.

This is how I currently move the character forward (basic script, found in the web some long time ago):

Code (CSharp):

1. public class MoveForward : MonoBehaviour
2. {
3.  
4.     public Rigidbody RigidBody;
5.     public float movementSpeed = 2.0f;
6.     public float clockwise = 250f;
7.     public float counterClockwise = -250f;
8.  
9.     void Start()
10.     {
11.  
12.     }
13.  
14.     void Update()
15.     {
16.  
17.          transform.position += transform.forward * Time.deltaTime * movementSpeed;
18.  
19.         if (Input.GetKey(KeyCode.S))
20.         {
21.             RigidBody.position -= transform.forward * Time.deltaTime * movementSpeed;
22.         }
23.         else if (Input.GetKey(KeyCode.A))
24.         {
25.             RigidBody.position -= transform.right * Time.deltaTime * movementSpeed;
26.         }
27.         else if (Input.GetKey(KeyCode.D))
28.         {
29.             RigidBody.position += transform.right * Time.deltaTime * movementSpeed;
30.         }
31.  
32.         if (Input.GetKey(KeyCode.E))
33.         {
34.             transform.Rotate(0, Time.deltaTime * clockwise, 0);
35.         }
36.         else if (Input.GetKey(KeyCode.Q))
37.         {
38.             transform.Rotate(0, Time.deltaTime * counterClockwise, 0);
39.         }
40.     }
41. }

I'm wondering: What causes this "jitter", and how could I get rid of it?

 

Did you see this jitter before connecting the character to the controller?

So - I would trouble shoot this by first importing the model into the game and viewing the animation alone. Then getting the animation to work in the game with a simple state machine. Then attaching a simple move script, for only that forward animation, not a complete controller.

If these steps result in no issues - the problem is in the character controller code. I'm not a programmer so I can't help in that area.

 

Thanks for your reply!

Yeah, you are right: This only happens as soon as the character moves forward. It looks like it's out of sync or sth...

 

Hmm - maybe it is a result of the way the animation is created, not syncing with the framerate of the game?
What framerate did you create the animation at?

Since the game is a variable framerate - I don't know - this is beyond my knowledge - can the framerate of the game be locked at a specific rate (60fps) so then the animation could match the frame rate of the game exactly?

 

That's an interesting idea. I had 21 single frames, running with a stepping of 0.048 per frame. Yes, I tinkered around with different types of settings. But for now, I guess there are too many parameters that might cause the issue, or at least influence it.

At the end, I think it might not be worth the hassle. I'll go the good ol' rigging route, although it would have looked cool from what I saw. Thanks for your help so far!
