移动平台上站立会禁止移动

当角色处于移动平台上时，将其速度与平台的速度相加，以使其相对于整个世界保持相同的速度。以下是示例代码：

public class MovingPlatform : MonoBehaviour { private void OnCollisionEnter2D(Collision2D collision) { if (collision.gameObject.CompareTag("Player")) { collision.transform.SetParent(transform); } }

private void OnCollisionExit2D(Collision2D collision)
{
    if (collision.gameObject.CompareTag("Player"))
    {
        collision.transform.SetParent(null);
    }
}

private void FixedUpdate()
{
    foreach (Transform child in transform)
    {
        Rigidbody2D rb = child.GetComponent<Rigidbody2D>();
        if (rb != null)
        {
            Vector2 velocity = GetComponent<Rigidbody2D>().velocity;
            rb.velocity = velocity + GetComponent<Rigidbody2D>().velocity;
        }
    }
}

}
