Basic questions related to speed control HELP!!!!!!!!!

[jun12321]

You are trying to adjust the speed in another script.



But it was vThirdPersonMotor who made the public declaration, not vThirdPersonController.



I want to adjust the speed in the new script.

However, as in the example, these scripts do not solve the problem.

Is there a solution?

plz I want to import and adjust the speed variable from the new script and apply it.

I'm a beginner so I want you to show me the resolved code 
Finally, if you use root motion, you can see the rigid body,

They say you can use extra speed, but I don't know what it means.

Could you please let me know?

using System.Collections;

using System.Collections.Generic;

using System.Security.Cryptography;

using UnityEngine;

using static Invector.vCharacterController.vThirdPersonMotor;



public class Controller : MonoBehaviour

{



   GameObject ob;

   public float i;

   private float Bottomtime = -1.0f;

   public float intervel = 0.25f;

   void Start()

   {

       i = ob.GetComponent<vMovementSpeed>().runningSpeed;

   }





   void Update()

   {

       if (Input.GetKeyDown(KeyCode.V))

       {

           if ((Time.time - Bottomtime) < intervel)

           {



               i = 4f;

               Bottomtime = -1.0f;

           }

           else

           {

               i = 8f;

               Bottomtime = Time.time;

           }



       }



   }

}
