Unity 3D is a popular multi-platform game engine that has been used for over 10 years. It uses scenes to organize game levels and objects. Gameplay is created using game objects, components, transforms, lights, cameras, inputs, and triggers. Common tasks for a beginner project include creating a maze with a movable character controller and trigger that removes the floor.

19. Home Task
1. Create maze. (Add colors and lights)
2. Create movable controller. (Sphere or capsule)
3. At the end of the way create trigger which removed floor under the controller.
4. (Optional) Add camera to the controller and turn it with A and D keys.

20. Move Character
public class MoveController : MonoBehaviour {
public float speed = 6.0F;
public float jumpSpeed = 8.0F;
public float gravity = 20.0F;
private Vector3 moveDirection = Vector3.zero;
void FixedUpdate()
{
CharacterController controller = GetComponent<CharacterController>();
if (controller.isGrounded)
{
moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
moveDirection = transform.TransformDirection(moveDirection);
moveDirection *= speed;
if (Input.GetButton("Jump"))
moveDirection.y = jumpSpeed;
}
moveDirection.y -= gravity * Time.deltaTime;
controller.Move(moveDirection * Time.deltaTime);
}
}
public class MoveRigidbody: 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);
}
}
