Building the Game

Summary

The Roll-a-ball Project is a simple rolling ball game that teaches you many of the principles of working with Unity.
The 4th of 4 tutorials in the project shows how to create the "Pick Up" collectables, place them on the play area, add a script enabling the ball to pick up those collectables, and make a simple scoring system. Finally, we demonstrate how to create a "build" of the game that will run outside of the Unity Engine.

Collecting, Scoring and Building the Game

Creating Collectable Objects

Creating and placing the "Pick Up" collectables.
 
Rotator
using UnityEngine;
using System.Collections;

public class Rotator : MonoBehaviour {

    void Update () 
    {
        transform.Rotate (new Vector3 (15, 30, 45) * Time.deltaTime);
    }
}

Collecting the Pick Up Objects

Collecting the pick-up objects; discussing physics, collisions and triggers.
 
This code reflects the current state of the script as of the end of this particular lesson. This script will continue to grow and mature as the series continues.
PlayerController
using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour {

    public float speed;

    private Rigidbody rb;

    void Start ()
    {
        rb = GetComponent<Rigidbody>();
    }

    void FixedUpdate ()
    {
        float moveHorizontal = Input.GetAxis ("Horizontal");
        float moveVertical = Input.GetAxis ("Vertical");

        Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);

        rb.AddForce (movement * speed);
    }

    void OnTriggerEnter(Collider other) 
    {
        if (other.gameObject.CompareTag ("Pick Up"))
        {
            other.gameObject.SetActive (false);
        }
    }
}

Displaying the Score and Text

Counting, displaying text and ending the game.
 
PlayerController
using UnityEngine;
using UnityEngine.UI;
using System.Collections;

public class PlayerController : MonoBehaviour {

    public float speed;
    public Text countText;
    public Text winText;

    private Rigidbody rb;
    private int count;

    void Start ()
    {
        rb = GetComponent<Rigidbody>();
        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);

        rb.AddForce (movement * speed);
    }

    void OnTriggerEnter(Collider other) 
    {
        if (other.gameObject.CompareTag ( "Pick Up"))
        {
            other.gameObject.SetActive (false);
            count = count + 1;
            SetCountText ();
        }
    }

    void SetCountText ()
    {
        countText.text = "Count: " + count.ToString ();
        if (count >= 12)
        {
            winText.text = "You Win!";
        }
    }
}
