Selecting one instantiate prefab

Questions & Answers

I am working on a squad size rts in 2d. I have some troop prefabs that you can spawn with a button but when I click on one of them all of them get selected. I need help getting only one of these instantiate prefab to be selected at on time.

public bool Selected ()
{
	
		Vector2 origin = new Vector2 (Camera.main.ScreenToWorldPoint (Input.mousePosition).x,
			Camera.main.ScreenToWorldPoint (Input.mousePosition).y);
		RaycastHit2D hit = Physics2D.Raycast (origin, Vector2.zero, 0f); //casts ray to hit somthing
	if (hit) {
		return true;
		} 
	else 
		{
		return false;
		}

	}

void Update () 
{		
     if (Input.GetMouseButtonDown (0)) // get input from the mouse
	{
		if (select == false) //checks if the unit is selected
		{ 
			select = Selected ();
		}
		else 
		{
			Debug.Log ("error 4");
			target = Camera.main.ScreenToWorldPoint (Input.mousePosition);
			target.z = transform.position.z;
			if (move == false)
				move = true;
			Instantiate (point, target, Quaternion.identity);
			select = false;
		}
   }

I am not sure want I am missing in my code to just select one of the instantiate prefab. please help.

Good day.

When you instantiate something, you can store the instantiated gameobject in a GameObject variable. Like this:

GameObject ObjectInstantiated = Instantiate (prefab, position, rotation);

So now, you can access that object as any other object, for example:

ObjectInstantiated.GetComponent<NavMeshAgent>().SetDestination(destination);

or

if (ObjectInstantiated.transform.position.x >= 25)
{
Destroy (ObjectInstantiated);
}

Bye!
