float horizontalInput = Input.GetAxis("Horizontal");
float verticalInput = Input.GetAxis("Vertical");

Vector3 movement = new Vector3(horizontalInput, 0, verticalInput) * speed * Time.deltaTime;

transform.Translate(movement);
}
}

In this script, the player’s movement is controlled by the horizontal and vertical input from the arrow keys or WASD keys.

The speed variable determines how fast the player moves, and Time.deltaTime ensures smooth movement across different devices.

To attach the script to a game object, simply drag and drop it onto the desired object in the Unity editor. Once attached, the script will be executed during gameplay, affecting the object’s behavior as intended.

Other common game mechanics, such as shooting projectiles, spawning enemies, or managing health and score systems, can also be implemented through scripting in Unity.
