Bug The animation events do not scale with animation speed Unity 2021.1?

Hi,

I'm having an issue with animation events, and I believe the problem has to do with animation event timings not scaling with the animation speed.

I have an animation with 6 frames. I fire two events at around 20% and 90% of the clip.

I added state machine behavior to my animation state to log some things:

Code (CSharp):

1. public class TestAnimBehavior : StateMachineBehaviour
2. {
3.     // OnStateEnter is called when a transition starts and the state machine starts to evaluate this state
4.     override public void OnStateEnter(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
5.     {
6.         Debug.Log(Time.frameCount+" ENTER FIRE ANIM STATE "+stateInfo.normalizedTime);
7.     }
8.     // OnStateUpdate is called on each Update frame between OnStateEnter and OnStateExit callbacks
9.     override public void OnStateUpdate(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
10.     {
11.         Debug.Log(Time.frameCount+" UPDATE FIRE ANIM STATE "+stateInfo.normalizedTime);
12.     }
13.     // OnStateExit is called when a transition ends and the state machine finishes evaluating this state
14.     override public void OnStateExit(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
15.     {
16.         Debug.Log(Time.frameCount+" EXIT FIRE ANIM STATE "+stateInfo.normalizedTime);  
17.     }
18.     // OnStateMove is called right after Animator.OnAnimatorMove()
19.     //override public void OnStateMove(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
20.     //{
21.     //    // Implement code that processes and affects root motion
22.     //}
23.     // OnStateIK is called right after Animator.OnAnimatorIK()
24.     //override public void OnStateIK(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
25.     //{
26.     //    // Implement code that sets up animation IK (inverse kinematics)
27.     //}
28. }

I would expect the events to fire around stateInfo.normalizedTime 0.2 and 0.9 no matter the animation speed.
But instead it gets fired at 0.2, 0.9 when speed is 1 and around 0,0001034698 and 0,0005153804 when using a speed of 0.001.


Does anyone know if that's a known bug? Or if I'm actually doing something wrong?
