	~~'''B) transform.Translate'''~~

	~~Similar to transform.position, but instead of assigning the GameObject a new position, it gives the GameObject an amount to move, data contained in a Vector3 struct.~~

	~~private void Update()~~
	{
	~~transform.Translate(Vector3.forward * Time.deltaTime);~~
	}


	~~'''C) RigidBody.AddForce'''~~

	'''RigidBody:''' Adding a Rigidbody component to a GameObject will put its motion under the control of Unity's physics engine, which is a long list of physical properties such as acceleration, mass, gravity, inertia, etc, as well as the capacity to react to other rigid bodies (for instance, collide).

	'''RigidBody.AddForce:''' Adds a force vector to the class Rigidbody. Force can be applied only to an active Rigidbody. If a GameObject is inactive, AddForce has no effect. Specifying the ForceMode mode allows the type of force to be changed to an Acceleration, Impulse or Velocity Change.

	~~public class RigidBodyAddForce : MonoBehaviour~~
	{
	~~public float forceMult = 200; //velocity float multiplier~~
	~~private Rigidbody rb; //declarate Class Rigidbody~~

	~~private void Awake()~~
	{
	~~rb = GetComponent<Rigidbody>();~~
	}

	~~private void Update()~~
	{
	~~rb.AddForce(transform.up * forceMult * Time.deltaTime);~~
	}
	}
	* The effect of the float forceMult (multiplier) over the RigidBody’s velocity is acceleration, it´s adding force every frame. A divider would be deceleration (transform.up / forceDiv).
	* GameObject is activated in private void Awake();
	* transform.up is the unit vector defined by (0, 0, 1).

	~~'''D) RigidBody.MovePosition'''~~

	Similar to transform.position but applied to a RigidBody, it sets the new position of the GameObject. Recommended to use with kinematic rigid bodies. When a RigidBody is marked as Kinematic, it will not be affected by collisions, forces, or any other part of Unity´s phisics engine.

	~~public class RigidBodyMovePosition : MonoBehaviour~~
	{
	~~public float forceMult = 100;~~
	~~private Rigidbody rb;~~

	~~private void Awake()~~

	{
	~~rb = GetComponent<Rigidbody>();~~
	}
	~~private void Update()~~
	{
	~~rb.MovePosition(transform.position + (transform.forward * Time.deltaTime));~~
	}
	}

	~~'''A) transform.position'''~~

	~~'''Transform:''' a Class which contains the information of position, rotation and scale of an object.~~

	~~'''transform.position:''' The position property of a GameObject's Transform. Assigns the object a new position.~~

	~~'''Vector:''' A Class refering to a mathematical entity commonly drewn as an arrow in two or three dimensional space, which has a a magnitude (size or length) and a direction (angle θ).~~

	~~'''Vector3:''' is a Unity C# struct with given x, y & z components, representing points and vectors in 3D space. In other words, a group of Vectors.~~

	~~example 1)~~
	~~private void Update()~~
	{
	~~transform.position += transform.forward * Time.deltaTime;~~
	}

	* the “f” is there to state that the variable 0.01 is of type float.

	~~example 2)~~
	~~void Update()~~
	{
	~~transform.position += new Vector3(0, 0, 0.01f);~~
	}

	*Vector3.forward is the unit vector defined by (0, 0, 1)
	*Time.deltaTime is a variable used so velocity is consistent across different frame rates.
