如何通过脚本更改ConfigurableJoint的角度？

ConfigurableJoint joint = GetComponent<ConfigurableJoint>();

JointDrive drive = new JointDrive();
drive.positionSpring = 100f; // 旋转的弹簧系数
drive.positionDamper = 10f; // 旋转的阻尼系数
drive.maximumForce = 100f; // 旋转的最大力矩

Quaternion targetRotation = Quaternion.Euler(0f, 90f, 0f); // 设置目标旋转角度为(0, 90, 0)
joint.targetRotation = targetRotation;

joint.angularXDrive = drive; // 应用到X轴旋转驱动器

using UnityEngine;

public class ChangeJointAngle : MonoBehaviour
{
    private ConfigurableJoint joint;

    private void Start()
    {
        joint = GetComponent<ConfigurableJoint>();
    }

    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            Quaternion targetRotation = Quaternion.Euler(0f, 90f, 0f);
            joint.targetRotation = targetRotation;

            JointDrive drive = new JointDrive();
            drive.positionSpring = 100f;
            drive.positionDamper = 10f;
            drive.maximumForce = 100f;

            joint.angularXDrive = drive;
        }
    }
}
