Question AnimatorController is UnityEditor ONLY. Why?

    I needed to find out the length of the animation by the name of the state in the animator.

    Here is the solution I came up with:
    Code (CSharp):
    1. using System;
    2. using UnityEditor.Animations;
    3. using UnityEngine;
    5. public static class AnimatorExtensions {
    6.     public static float GetLengthOfState(this Animator animator, string stateName) {
    7.         if (animator.runtimeAnimatorController is not AnimatorController animatorController) {
    8.             throw new Exception("Given animator has no AnimatorController.");
    9.         }
    11.         foreach (var animatorControllerLayer in animatorController.layers) {
    12.             foreach (var childAnimatorState in animatorControllerLayer.stateMachine.states) {
    13.                 if ( == stateName) {
    14.                     if (childAnimatorState.state.motion is AnimationClip animationClip) {
    15.                         return animationClip.length / childAnimatorState.state.speed;
    16.                     }
    17.                 }
    18.             }
    19.         }
    21.         throw new Exception("Couldn't find a state named as <color=yellow>" + stateName + "</color>");
    22.     }
    23. }
    This is a very useful method that returns me the exact time after which I execute the rest of the logic.

    When building the project, the compiler complains about the
    namespace, which is not included in the build.

    And what should I do now? Why can't I use what the game already uses?

    Are there any other similar methods? I would really hate to hardcode the animation duration value.
