Rigidbody2D.SetRotation

Parameters

Description

Sets the rotation of the Rigidbody2D to angle (given in degrees).

See Also: Rigidbody2D.rotation and Rigidbody2D.MoveRotation.

using UnityEngine;

// Rotate rigidBody2D every frame.
public class ExampleScript : MonoBehaviour
{
    public Rigidbody2D rigidBody2D;
    public float rotation = 0.0f;

    void Start()
    {
        rigidBody2D = GetComponent<Rigidbody2D>();
    }

    void Update()
    {
        rigidBody2D.SetRotation(rotation);

        rotation += 1.0f;
    }
}

Parameters

Description

Sets the rotation of the Rigidbody2D to the z-axis rotation extracted from the full 3D rotation.

The z-axis rotation is extracted from the given Quaternion rotation and used as the rotation for Rigidbody2D. 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.

using UnityEngine;

// Rotate rigidBody2D every frame.
public class ExampleScript : MonoBehaviour
{
    public Rigidbody2D rigidBody2D;
    public float rotation = 0.0f;

    void Start()
    {
        rigidBody2D = GetComponent<Rigidbody2D>();
    }

    void Update()
    {
        var quaternionRotation = Quaternion.Euler(0f, 0f, rotation);
        rigidBody2D.SetRotation(rotation);

        rotation += 1.0f;
    }
}
