using a button to stop running script

Question

Hi,

I have a cube which is moving on x and z axis i want to make a release button by which cube will stop moving and fall down to ground using gravity.

My code for movement is :

 using UnityEngine;
 using System.Collections;
 
 public class BlockMover : MonoBehaviour
 {
     // define the possible states through an enumeration
     public enum motionDirections { Spin, Horizontal, Vertical };
 
     // store the state
     public motionDirections motionState = motionDirections.Horizontal;
 
     // motion parameters
     public float spinSpeed = 180.0f;
     public float motionMagnitude = 0.05f;
 
     // Update is called once per frame
     private void Update()
     {
 
         // do the appropriate motion based on the motionState
         switch (motionState)
         {
             case motionDirections.Spin:
             // rotate around the up axix of the gameObject
             gameObject.transform.Rotate(Vector3.up * spinSpeed * Time.deltaTime);
             break;
 
             case motionDirections.Vertical:
             // move up and down over time
             gameObject.transform.Translate(Vector3.up * Mathf.Cos(Time.timeSinceLevelLoad) * motionMagnitude);
             break;
 
             case motionDirections.Horizontal:
             // move up and down over time
             gameObject.transform.Translate(Vector3.right * Mathf.Cos(Time.timeSinceLevelLoad) * motionMagnitude);
             break;
         }
     }
 }

Make sure you have Rigidbody on you GameObject. And then you can call DisableMoving() method for disabling movement and falling down. You can attach it to OnButtonClick in Unity-UI Button.

 public class BlockMover : MonoBehaviour
 {
     private bool m_disableMoving;
     private Rigidbody rb;
 
     private void Start()
     {
         rb = GetComponent<Rigidbody>();
     }
 
     // define the possible states through an enumeration
     public enum motionDirections { Spin, Horizontal, Vertical };
 
     // store the state
     public motionDirections motionState = motionDirections.Horizontal;
 
     // motion parameters
     public float spinSpeed = 180.0f;
     public float motionMagnitude = 0.05f;
 
     // Update is called once per frame
     private void Update()
     {
         if (!m_disableMoving)
         {
             // do the appropriate motion based on the motionState
             switch (motionState)
             {
                 case motionDirections.Spin:
                     // rotate around the up axix of the gameObject
                     gameObject.transform.Rotate(Vector3.up * spinSpeed * Time.deltaTime);
                     break;
 
                 case motionDirections.Vertical:
                     // move up and down over time
                     gameObject.transform.Translate(Vector3.up * Mathf.Cos(Time.timeSinceLevelLoad) * motionMagnitude);
                     break;
 
                 case motionDirections.Horizontal:
                     // move up and down over time
                     gameObject.transform.Translate(Vector3.right * Mathf.Cos(Time.timeSinceLevelLoad) * motionMagnitude);
                     break;
             }
         }
     }
 
     public void DisableMoving()
     {
         m_disableMoving = true; // activating bool, so movement will stop
         rb.isKinematic = false; // disable if it is kinematic, so it can now affect like dynamic physic body
         rb.useGravity = true; // we are using gravity, so object can drop to the ground
 
         // uncomment this if you want to freeze object in his position and drop to the gorund vertically
         //rb.velocity = Vector3.zero;
     }
 }
