Rigidbody2D.SetRotation

파라미터

설명

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

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;
    }
}

설명

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;
    }
