七巧板製作

1.將事先建好的七巧板模型匯入Unity，並加入Mesh Coilder以利後面做碰撞偵測


2.加入程式碼拿起七巧板


程式碼如下:
    void OnTriggerStay(Collider col) {       
        if (device.GetPress(SteamVR_Controller.ButtonMask.Trigger) && col.tag!="desk"){   
            //Debug.Log ("抓起");       
            // 將 physics(物理引擎) 關掉            
            col.attachedRigidbody.isKinematic = true;         
            // 設定controller為parent            
            col.gameObject.transform.SetParent(gameObject.transform);
        }     
        if (device.GetPressUp (SteamVR_Controller.ButtonMask.Trigger)) {               
            col.gameObject.transform.SetParent (null);           
            col.attachedRigidbody.isKinematic = false;           
            //GameObject.Destroy (col.gameObject, 3f);            
            //tossObject (col.attachedRigidbody);        
        }   
    } 

3.過關條件判斷
單個七巧板放置在木板上時，設定布林值為真。當所有的七巧板都放在木板上，每塊七巧板的布林值皆為真，即達成過關條件

布林值條件程式碼:
    void OnCollisionStay(Collision other) {
        if(other.gameObject.tag=="desk")
            blue=true;
    }

    void OnCollisionExit(Collision other) {
        if(other.gameObject.tag=="desk")
            blue=false;
    }

過關條件程式碼:
    void Update () {       
        device = SteamVR_Controller.Input ((int)trackedObj.index);     
        if(col_blue.blue&&col_gray.gray&&col_green.green&&col_orange.orange&&col_yellow.yellow&&col_purple.purple&&col_red.red&&col_black.black)
        {
            puzzover=true;
            SceneManager.LoadScene ("start_menu");
        }
    }

4.加入移動角色的程式碼，好移動拿取七巧板
(以原先旋轉物體的程式碼做修改)
程式碼:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class tranlate : MonoBehaviour
{
    // Start is called before the first frame update
    SteamVR_TrackedObject trackedObj;
SteamVR_Controller.Device device,deviceLeft,deviceRight;
    public GameObject obj;
    float a=0.0f,b=0.0f,c=0.0f;
    Vector2 rotat=new Vector2(0.0f,0.0f);
    void Start()
    {
        trackedObj=GetComponent<SteamVR_TrackedObject>();
a=obj.transform.position.x;
b=obj.transform.position.y;
c=obj.transform.position.z;
    }

    // Update is called once per frame
    void Update()
    {
        device = SteamVR_Controller.Input ((int)trackedObj.index);
        if (device.GetPress (SteamVR_Controller.ButtonMask.Touchpad)){
rotat = device.GetAxis ();
float angle=Vector2.Angle (new Vector2 (1, 0), rotat);
if (angle > 45 && angle < 135) {
if (rotat.y > 0)
c+=0.02f;
else
c-=0.02f;
}
else {
if (rotat.x>0)
a+=0.02f;
else
a-=0.02f;
}
}
obj.transform.position = (new Vector3 (a, b, c));
