Resetting a position after reaching a certain point

Question

I'm currently working on a game that has moving cars moving through my stage. I want to be able to return to their original positions once they reach a certain point, but the code I'm using doesn't seem to work. Relatively new to C#, any help would be appreciated.

 using UnityEngine;
 using System.Collections;
 
 public class CarmovingX : MonoBehaviour {
     
     public int maxXPosition = 50;
 
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
       transform.Translate(Vector3.up * Time.deltaTime);
         
         if( gameObject.transform.position.x >= maxXPosition)
         {
             transform.Translate(Vector3(12,y,z));
         }
         
     }
 }

Thanks

I suggest you to store original position and orientation of your GameObject. When you decide to restore them, simply assign the stored value to its Transform. An example:

 public class CarmovingX : MonoBehaviour {
 
     public int maxXPosition = 50;
     private Vector3 initialPos;
     private Quaternion initialRotation;
 
     // Use this for initialization
     void Start () {
         initialPos = transform.position;
         initialRotation = transform.rotation;
     }
 
     // Update is called once per frame
     void Update () {
       transform.Translate(Vector3.up * Time.deltaTime);
 
        if( gameObject.transform.position.x >= maxXPosition)
        {
             transform.rotation = initialRotation;
             transform.position = initialPosition;
        }
 
     }
 }

If your CarmovingX GameObject is child of another GameObject, you may consider using Transform.localPosition and Transform.localRotation instead.

For some reason my gameObject became very jittery. However, the example worked perfectly once I removed the following line.

 transform.Translate(Vector3.up * Time.deltaTime);

I used this script for my own project, i just had to replace the X axis by a Y axis to fit my needs. works well but i would like to only reset to initial position on the Y and Z axis how can I stop the script form reseting the gameobject's position along the X axis ?
