public void MoveRotation (float angle);


angle@param angle El nuevo ángulo de rotación para el objeto Rigidbody.


Rotates the Rigidbody to angle (given in degrees).

Rotates the Rigidbody to the specified angle by calculating the appropriate angular velocity required to rotate the Rigidbody to that angle during the next physics update. During the move, angular drag won't affect the body. This causes the object to rapidly move from the existing angle to the specified angle.

Because this feature allows a Rigidbody to be rotated rapidly to the specified angle, any colliders attached to the Rigidbody will react as expected i.e. they will produce collisions and/or triggers. This also means that if the colliders produce a collision then it will affect the Rigidbody movement and potentially stop it from reaching the specified angle during the next physics update. If the Rigidbody is kinematic then any collisions won't affect the Rigidbody itself and will only affect any other dynamic colliders.

Rigidbody2D components have a fixed limit on how fast they can rotate therefore attempting to rotate large angles over short time-scales can result in the Rigidbody not reaching the specified angle during the next physics update. It is recommended that you use this for relatively small rotational movements only.

Es importante entender que un cambio en la rotación real solo ocurrirá durante la próxima actualización de la física; por tanto, estar llamando a este método repetidamente sin esperar a la próxima actualización resultará en que solo sea usada la última actualización. Por esta razón, es recomendado que sea invocado durante la llamada al método FixedUpdate.

// MoveRotation
// The sprite is set a rotation speed.

using UnityEngine; using System.Collections;

public class Example : MonoBehaviour { public Texture2D tex;

private Rigidbody2D rb2D; private Sprite mySprite; private SpriteRenderer sr; private float revSpeed = 50.0f;

void Awake() { sr = gameObject.AddComponent<SpriteRenderer>(); rb2D = gameObject.AddComponent<Rigidbody2D>(); }

void Start() { mySprite = Sprite.Create(tex, new Rect(0.0f, 0.0f, tex.width, tex.height), new Vector2(0.5f, 0.5f), 100.0f); transform.localScale = new Vector3(3.0f, 3.0f, 3.0f); rb2D.gravityScale = 0.0f; sr.sprite = mySprite; }

void FixedUpdate() { rb2D.MoveRotation(rb2D.rotation + revSpeed * Time.fixedDeltaTime); } }


rotationFull 3D rotation used to extract only the z-axis rotation.


An overload of MoveRotation that allows a full 3D rotation as an argument.

The z-axis rotation is extracted from the given Quaternion rotation and used as a target angle to move the Rigidbody2D to. It is important to understand that the full 3D rotation isn't used because the Rigidbody2D only has a single degree of rotational freedom around the z-axis.
