A dropdown selector for an animator parameter.

• string animatorName=null

  name of the animator. When omitted, it will try to get the animator from the current component

• (Optional) AnimatorControllerParameterType animatorParamType

  type of the parameter to filter

using SaintsField;

[field: SerializeField]
public Animator Animator { get; private set;}

[AnimatorParam(nameof(Animator))]
private string animParamName;

[AnimatorParam(nameof(Animator))]
private int animParamHash;

It works with ShowInInspector:

[ShowInInspector, AnimatorParam(nameof(MyAnimator))]
public int ShowAnimParamHash
{
    get => animParamHash;
    set => animParamHash = value;
}

[ShowInInspector]
[AnimatorParam]
private int ShowAnimatorParam([AnimatorParam] string animName) => Animator.StringToHash(animName);

[Button]
[AnimatorParam]
private int ShowAnimatorParam([AnimatorParam] string animName) => Animator.StringToHash(animName);
