public AnimatorControllerParameter[] parameters ;

설명

Parameters are used to communicate between scripting and the controller. They are used to drive transitions and blendtrees for example.

It's important to note that the AnimatorControllerParameters are returned as a copy. The array should be set back into the property when changed.

using UnityEngine;
using UnityEditor;

class ControllerModifier { UnityEditor.Animations.AnimatorController controller;

public void ModifyParameters(int parameterIndex, string newName) { AnimatorControllerParameter[] parameters = controller.parameters; parameters[parameterIndex].name = newName; controller.parameters = parameters; } }
