Question

当你点击屏幕时，我有一个从摇摆杆释放的球。当被抛掷的球与另一个摆动杆碰撞时，我将一个铰链接头添加到球上并将其连接到杆的末端。然而，负责碰撞的圆形对撞机不在杆的末端。因此，当我碰到圆圈碰撞时，它将球附着在杆的末端但是它会卡入到位。我希望它看起来像是顺利地移动到位而不是立即卡入到位。

我怎样才能顺利地将其移动到那个位置？

这是我在检测到碰撞时用来附加球的脚本：

using UnityEngine;
using System.Collections;

public class attachBall : MonoBehaviour {

public GameObject player;
public GameObject rope;
public HingeJoint2D hinge;
public Rigidbody2D rb;
public CircleCollider2D coll;
public GameObject cameraObject;
public float move;
public float x;

void OnTriggerEnter2D(Collider2D collider) {

    if (collider.tag == "rope") 
    {
        player = GameObject.FindGameObjectWithTag ("Player");
        player.AddComponent<HingeJoint2D> ();
        rope = collider.gameObject;
        hinge = player.GetComponent<HingeJoint2D>();
        rb = rope.GetComponent<Rigidbody2D>();
        hinge.connectedBody = rb;
        hinge.connectedAnchor = new Vector2(0,2.5f);
        rope.GetComponent<CircleCollider2D>().enabled = false;
        addPoint.scorePoint();
    }
}

void Update()
{
    x = this.gameObject.transform.position.x;
    cameraObject.transform.position = new Vector3 (x, 0, 0);
}
}

Answer 1

有人在这里放了一个不起作用的答案，然后很快将其删除。但是，在那个答案中我看到了：

Vector3.MoveTowards

这激发了想象力，我想出来了。我的对象是用池创建的。在其中一个合并的对象上，我在条形的末尾添加了一个空对象。然后我得到了那个物体的位置，因为它绕着盘旋并用Vector2.MoveTowards将我的球员（球）移向它。然后我匹配了球的Vector2位置和空的游戏对象，并说如果它们匹配停止移动并连接我的铰链接头。

using UnityEngine;
using System.Collections;

public class attachBall : MonoBehaviour {

public GameObject player;
public GameObject endOfLine;
public Vector2 endOfLineCoords;
public Vector2 playerCoords;
public GameObject rope;
public HingeJoint2D hinge;
public Rigidbody2D rb;
public CircleCollider2D coll;
public GameObject cameraObject;
public float move;
public float x;
public static bool attach = false;
public static bool connected = false;

void OnTriggerEnter2D(Collider2D collider) {

    if (collider.tag == "rope") 
    {
        attach = true;
        rope = collider.gameObject;
        endOfLine = rope.transform.Find("endOfLine").gameObject;
        addPoint.scorePoint();
    }
}

void Update()
{
    if (attach == true && connected == false) {
        moveToPosition ();
    }
    moveCamera();
}

void moveCamera()
{
    x = this.gameObject.transform.position.x;
    cameraObject.transform.position = new Vector3 (x, 0, 0);
}

void moveToPosition()
{
    if (connected == false)
    {
        player = GameObject.FindGameObjectWithTag ("Player");
        //endOfLine = GameObject.FindGameObjectWithTag ("endOfLine");
        playerCoords = player.transform.position;
        endOfLineCoords = endOfLine.transform.position;
        player.transform.position = Vector2.MoveTowards (playerCoords, endOfLineCoords, .5f);
    } 

    if(playerCoords == endOfLineCoords)
    {
        connected = true;   
        player.AddComponent<HingeJoint2D> ();
        hinge = player.GetComponent<HingeJoint2D>();
        rb = rope.GetComponent<Rigidbody2D>();
        hinge.connectedBody = rb;
        hinge.connectedAnchor = new Vector2(0,2.5f);
        rope.GetComponent<CircleCollider2D>().enabled = false;
    }
}

}

我现在唯一的问题是，当我减慢球移向空游戏物体的速度时，它有时无法与它匹配，并且试图抓住它的反弹类型。我想我可以通过设置一个if语句来修复这个问题，当球接近物体VS与它处于同一坐标时附着铰链接头。

发布临时答案的人。谢谢= D

安装铰链接头时，将物体平滑移动到位置
