JointDrive.positionSpring

说明

朝着已定义方向施加的橡皮筋拉力强度。仅在mode包含位置时使用。

using UnityEngine;

public class Example : MonoBehaviour
{
    // Create a JointDrive, configure it and assign the JointDrive to
    // the zDrive element of a configurable joint.

    void Start()
    {
        ConfigurableJoint joint = gameObject.AddComponent<ConfigurableJoint>();
        joint.targetPosition = new Vector3(0, 0, -10);

        JointDrive drive = new JointDrive();
        drive.mode = JointDriveMode.Position;
        drive.positionSpring = 20;

        joint.zDrive = drive;
    }
