detecting whether the object has been clicked in another script

Question

Currently, I have an object A (attached with script A), the function of script A is that when user click on the scene, object A will appear. Object A can be clicked multiple times, depends on the user.

There will be another object called object B. When object A appears on the scene(after clicking), object B will appear next to object A.

What I want to achieve:

know that the object A has been clicked within script A
tell object B to appear on the scene
tell object B to appear right next to object A

So I only write a little bit on script B as I don't know where to start.... but script A is completed

     public class object_B : MonoBehaviour {
     
         public Renderer rend;
     
         // Use this for initialization
         void Start () {
             
             rend = this.GetComponent<Renderer> ();
             // make the object invisible
             rend.enabled = false;
     
         }
         
         // Update is called once per frame
         void Update () {
         
         }
     }

You don't need to add another script for object B, Just adjust the object B next to object A as you like from the Scene, also disable it from the Inspector (you will able to do it from a checkbox beside your object name in the inspector or you can simply do it within the script itself, just write : GameObject.Find ("object_B_name").active = false; in the Start ( ) function) . Add a collider to Object A.

Also add this code to script :

 void OnMouseDown()
     {
         GameObject.Find ("object_B_name").active = true;
     }

Attach the script and collider to A only, no need to add anything to B.

Sounds like you should have some sort of "manager" script. Have the manager spawn in object A and object B. If object A or object B are clicked, it reports the click back to the manager. From there you can do whatever. When the objects are spawned in, access the script and make a reference to the manager.

On the objects you could have something like this...

     public class AnObject : MonoBehaviour
     {
         public enum ObjectType
         {
             objectA,
             objectB
         }
         public ObjectType typeOfObject;
         public ObjectManager manager;
 
         //called by the objectmanager to set this object up
         public void Setup(ObjectManager o, ObjectType ot)
         {
             typeOfObject = ot;
             manager = o;
         }
 
         //when this object is clicked, call this
         public void Clicked()
         {
             manager.Clicked(this);
         }
     }

And your manager could be:

 public class ObjectManager : MonoBehaviour
     {
         public GameObject objectPfb;
 
 
         void Start()
         {
             SpawnObject(Vector3.zero, AnObject.ObjectType.objectA);
         }
 
         //spawns an object at the pos as the type
         void SpawnObject(Vector3 pos, AnObject.ObjectType ot)
         {
             //instantiate the prefab of our object
             GameObject g = (GameObject)Instantiate(objectPfb, pos, Quaternion.identity);
             //setup the object
             g.GetComponent<AnObject>().Setup(this, ot);
         }
 
         //called by an object when that object is clicked
         public void Clicked(AnObject objClicked)
         {
             //do whatever you want with this object
             if (objClicked.ObjectType == AnObject.ObjectType.objectA)
             {
                 SpawnObject(new Vector3(objClicked.transform.position.x + 1, objClicked.transform.position.y, objClicked.transform.position.z), AnObject.ObjectType.objectB);
             }
             else if (objClicked.ObjectType == AnObject.ObjectType.objectB)
             {
                 //whatever you want with object B
             }
         }
     }
