Questions & Answers
1

I need to have a script where it will find all the objects under the tag “Pickup” so that It can put it to this text I have saying how many you’ve collected so far out of total and I want it to find the total when the game starts.

using UnityEngine;
strong textusing System.Collections;

public class Player_Controller : MonoBehaviour
{
	public float speed;
	public GUIText countText;
	public GUIText winText;
	private int count;
	void Start(){
				count = 0;
				SetCountText ();
				winText.text = "";
	}
	
	void FixedUpdate()
		{
			float moveHorizontal = Input.GetAxis("Horizontal");
			float moveVertical = Input.GetAxis("Vertical");
			Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);

			rigidbody.AddForce(movement * speed * Time.deltaTime);
		}
		void OnTriggerEnter(Collider other)
		{
			if (other.gameObject.tag == "Pickup") 
			{
				other.gameObject.SetActive (false);
				count = count + 1;
				SetCountText();
			}
		}

//Below here is where I make the level complete text come up.

	void SetCountText()
	{
		countText.text = "Count: " + count.ToString ();
		if (count >= 12 //<-- I want to make a variable replace total right here. ) 
			{
			winText.text = "Level Complete";
			}
	}
}

FindGameObjectsWithTag() will do what you need:

int remaining = GameObject.FindGameObjectsWithTag("Pickup").Length;
