Unity 6 Beginner Tutorial: Project Setup and First Game Foundation

steps

1. Open Unity Hub on your computer.
2. Click New Project.
3. In the template selection view, choose Universal 3D from the list of available templates.
4. Name your project (for example, "tutorial").
5. Disable Unity Version Control before creating it.
6. Click Create project to generate your project and launch the Unity editor.

steps

1. Create the ground: In the Hierarchy, right-click, choose 3D Object > Cube, and rename it to ground.
2. Set ground transform: In the Inspector, set Position to (0, 0, 0). Set Scale to X: 20, Y:1, Z:20 for a wide platform.
3. Create the player: In the Hierarchy, right-click, choose 3D Object > Cube, and rename it to player. Set position to X:0, Y:1, Z:0 to sit above the ground.
4. Create the coin: In the Hierarchy, right-click, choose 3D Object > Cube, and rename it to coin. Move it off the player and set its Scale to 0.5 on each axis to make it smaller.
5. Assign materials (optional): Create a Materials folder in the Project window, make new materials, and drag them onto objects for distinct colors.

steps

1. Add Coin Spawner script: With Coin Spawner selected, click Add Component, choose New Script, and name it "CoinSpawner".
2. Paste the spawning code: Use this script to instantiate coins at random ground positions:
   Copy

   using UnityEngine;
   
   public class CoinSpawner : MonoBehaviour
   {
       [SerializeField] private GameObject coinPrefab;
       [SerializeField] private BoxCollider groundCollider;
       [SerializeField] private int coinAmount = 20;
   
       void Start()
       {
           for (int i = 0; i < coinAmount; i++)
           {
               Vector3 pos = GetRandomPointInBounds(groundCollider.bounds);
               Instantiate(coinPrefab, pos, Quaternion.identity);
           }
       }
   
       Vector3 GetRandomPointInBounds(Bounds bounds)
       {
           float x = Random.Range(bounds.min.x, bounds.max.x);
           float z = Random.Range(bounds.min.z, bounds.max.z);
           return new Vector3(x, 1, z); // Y set to 1 to sit above ground
       }
   }

3. Connect assets in Inspector: Drag the ground (its Box Collider) and the Coin prefab from the Project window onto their fields in the Coin Spawner.
4. Add Player handler script: On the player object, Add Component > New Script, name it "PlayerHandler". Also add Rigidbody for physics.
5. Player movement code:
   Copy

   using UnityEngine;
   
   public class PlayerHandler : MonoBehaviour
   {
       private Rigidbody rb;
       [SerializeField] private float playerSpeed = 10f;
       private int points = 0;
   
       void Awake()
       {
           rb = GetComponent<Rigidbody>();
       }
   
       void FixedUpdate()
       {
           float h = Input.GetAxis("Horizontal");
           float v = Input.GetAxis("Vertical");
           Vector3 move = new Vector3(h, 0, v);
           rb.MovePosition(rb.position + move * playerSpeed * Time.fixedDeltaTime);
       }
   
       public void IncreasePoints()
       {
           points++;
       }
   }

6. Add Camera follow script: On a camera object (Create Empty, add Camera if needed), add this script:
   Copy

   using UnityEngine;
   
   public class FollowPlayer : MonoBehaviour
   {
       [SerializeField] private Transform target;
       [SerializeField] private Vector3 offset = new Vector3(0, 10, -10);
       [SerializeField] private float smoothTime = 0.25f;
       private Vector3 velocity = Vector3.zero;
   
       void FixedUpdate()
       {
           Vector3 desiredPosition = target.position + offset;
           transform.position = Vector3.SmoothDamp(transform.position, desiredPosition, ref velocity, smoothTime);
           transform.LookAt(target.position);
       }
   }

7. Assign camera target: In the Inspector, set the camera script's target to the player, set offset Y:10 Z:-10, and smooth time 0.25.
