Question

我已经用一个机器建模了多个零件。我希望能够在拖动鼠标左键的同时将部件“卡入”到位。如下面的视频：

这是我的代码：

JS

 #pragma strict

 var partnerName = "Hub";
 var closeVPDist = 0.05;
 var moveSpeed = 40.0;
 var rotateSpeed = 90.0;

 var closeColor = Color(1,0,0);

 private var dist = Mathf.Infinity;
 private var normalColor : Color;
 private var partnerGO : GameObject;

 function Start() {
     normalColor = renderer.material.color;
     partnerGO = GameObject.Find(partnerName);
 }

 function OnMouseDrag() {
     var partnerPos = Camera.main.WorldToViewportPoint(partnerGO.transform.position);
     var myPos = Camera.main.WorldToViewportPoint(transform.position);
     dist = Vector2.Distance(partnerPos, myPos);
     renderer.material.color = (dist < closeVPDist) ? closeColor : normalColor;
 }

 function OnMouseUp() {
     if (dist < closeVPDist) {
         transform.parent = partnerGO.transform;
         InstallPart();
     }
 }

 function InstallPart() {
     while (transform.localPosition != Vector3.zero || transform.localRotation != Quaternion.identity) {
         transform.localPosition = Vector3.MoveTowards(transform.localPosition, Vector3.zero, Time.deltaTime * moveSpeed);
         transform.localRotation = Quaternion.RotateTowards(transform.localRotation, Quaternion.identity, Time.deltaTime * rotateSpeed);
         yield;
     }
 }

通过单击GO并将其转到“伙伴”GO来工作...但我希望能够点击GO并将其拖动到正确的位置，然后将其捕捉到的地方。

编辑：

将以下脚本添加到每个对象，并结合之前的脚本让我更进一步。我现在需要弄清楚的是，如果没有足够接近合作伙伴GO，它们会重新回到原来的位置。想法？

C＃

private Vector3 screenPoint;
    private Vector3 offset;

    void OnMouseDown(){
        screenPoint = Camera.main.WorldToScreenPoint(gameObject.transform.position);
        offset = gameObject.transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z));
    }

    void OnMouseDrag(){
        Vector3 cursorPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);
        Vector3 cursorPosition = Camera.main.ScreenToWorldPoint(cursorPoint) + offset;
        transform.position = cursorPosition;
    }

如何让游戏对象“快速”到位？
