winform內嵌unity（二.控制新建預設體）

環境同一
代碼如下

1. 編輯unity界面
   新建3Dobject panel 新建控制空對象Gameobject 新增小球預設體並添加基本剛體碰撞等
   
   
2. 添加小球移動腳本

using UnityEngine;
using System.Collections;

public class move02 : MonoBehaviour
{
    public void Left()
    {
        transform.Translate(Vector3.left * Time.deltaTime * 5);
    }

    public void Right()
    {
        transform.Translate(Vector3.right * Time.deltaTime * 5);
    }

    public void Forward()
    {
        transform.Translate(Vector3.forward * Time.deltaTime * 5);
    }

    public void Back()
    {
        transform.Translate(Vector3.back * Time.deltaTime * 5);
    }

    public void Up()
    {
        transform.Translate(Vector3.up * Time.deltaTime * 5);
    }

    public void Down()
    {
        transform.Translate(Vector3.down * Time.deltaTime * 5);
    }
}

3. gameobject中添加新建預設體小球腳本

using UnityEngine;
using System.Collections;
using System;

public class newSphere : MonoBehaviour
{
    public GameObject boxBody; //障礙物
    private static int i = 1;
    private static int a = 0;

    // Use this for initialization
    private void Start()
    {
    }

    // Update is called once per frame
    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.R))
        {
            AppearPosition();
        }
    }

    private void AppearPosition()
    {

        Vector3 bodyAppearPosition = new Vector3(a, 0, 0);
        Quaternion bodyAppearRotation = Quaternion.identity;
        boxBody.name = "neweee" + i;

        // Application.ExternalCall(boxBody.name);
        Application.ExternalEval(boxBody.name); // 參數傳遞給winform，winform中有lable框時測試用的，此處可註釋，可看第一篇
        i++;
        a += 2;
        Instantiate(boxBody, bodyAppearPosition, bodyAppearRotation);
    }
}

4. MainCamera中增加點擊或移動新建預設體小球腳本

拖拽移動

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ModelDrage : MonoBehaviour
{
    private Camera cam;//發射射線的攝像機
    private GameObject go;//射線碰撞的物體
    public static string btnName;//射線碰撞物體的名字
    private Vector3 screenSpace;
    private Vector3 offset;
    private bool isDrage = false;

    private void Start()
    {
        cam = Camera.main;
    }

    private void Update()
    {
        //整體初始位置
        Ray ray = cam.ScreenPointToRay(Input.mousePosition);
        //從攝像機發出到點擊座標的射線
        RaycastHit hitInfo;
        if (isDrage == false)
        {
            if (Physics.Raycast(ray, out hitInfo))
            {
                //劃出射線，只有在scene視圖中才能看到
                Debug.DrawLine(ray.origin, hitInfo.point);
                go = hitInfo.collider.gameObject;
                //print(btnName);
                screenSpace = cam.WorldToScreenPoint(go.transform.position);
                offset = go.transform.position - cam.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenSpace.z));
                //物體的名字
                btnName = go.name;

                //發送給winform
                //   Application.ExternalEval(btnName);

                //組件的名字
            }
            else
            {
                btnName = null;
            }
        }
        if (Input.GetMouseButton(0))
        {
            Vector3 currentScreenSpace = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenSpace.z);
            Vector3 currentPosition = cam.ScreenToWorldPoint(currentScreenSpace) + offset;
            if (btnName != null)
            {
                go.transform.position = currentPosition;
            }

            isDrage = true;
        }
        else
        {
            isDrage = false;
        }
    }
}

點擊獲取對象（傳遞對象名給winform需要控制的對象）

using UnityEngine;
using System.Collections;

public class ModelDrage02 : MonoBehaviour
{
    // Use this for initialization
    private void Start()
    {
    }

    // Update is called once per frame
    private void Update()
    {
        if (Input.GetMouseButtonDown(0))
        {
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            RaycastHit hit;
            if (Physics.Raycast(ray, out hit))
            {
                GameObject go = hit.collider.gameObject;    //獲得選中物體
                string goName = go.name;    //獲得選中物體的名字，使用hit.transform.name也可以
                Application.ExternalEval(goName);
                print(goName);
            }
        }
    }
}

6. webplayer發佈unity項目
7. vs新建winform項目
   
8. 設計winform面板如下
   
9. 代碼編輯

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace UnityIntoWinformTest08
{
    public partial class Form1 : Form
    {
        private static string abc;
        private static string def;

        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            axUnityWebPlayer1.SendMessage(eToNew(), "Left", null);
        }

        private void button2_Click(object sender, EventArgs e)
        {
            axUnityWebPlayer1.SendMessage(eToNew(), "Right", null);
        }

        private void button3_Click(object sender, EventArgs e)
        {
            axUnityWebPlayer1.SendMessage(eToNew(), "Forward", null);
        }

        private void button4_Click(object sender, EventArgs e)
        {
            axUnityWebPlayer1.SendMessage(eToNew(), "Back", null);
        }

        private void button5_Click(object sender, EventArgs e)
        {
            axUnityWebPlayer1.SendMessage(eToNew(), "Up", null);
        }

        private void button6_Click(object sender, EventArgs e)
        {
            axUnityWebPlayer1.SendMessage(eToNew(), "Down", null);
        }

        private void button7_Click(object sender, EventArgs e)
        {
            axUnityWebPlayer1.SendMessage("GameObject", "AppearPosition", null);
        }

        private void axUnityWebPlayer1_OnExternalCall(object sender, AxUnityWebPlayerAXLib._DUnityWebPlayerAXEvents_OnExternalCallEvent e)
        {
            label1.Text = e.value;
        }

        private void button8_Click(object sender, EventArgs e)
        {
        }

        private void Form1_Load(object sender, EventArgs e)
        {
        }

        private void label1_Click(object sender, EventArgs e)
        {
        }

        private string eToNew()
        {
            ///  abc = label1.Text.Substring(0, label1.Text.Length - 1) + "(Clone)";
            abc = label1.Text.Substring(0, label1.Text.Length - 1);
            return abc;
        }

        private string eToBtn()
        {
            def = label1.Text.Substring(0, label1.Text.Length - 1) + "(Clone)";
            return def;
        }
    }
}

10. unity src加上剛發佈的unity地址
11. ok，運行界面 大功告成
    
    new幾個預設體小球
    
    點擊其中一個小球，label出現該小球名（在代碼裏預設的名字）
    
    然後就可以單獨點擊winform 前後左右 移動了 ，當然， 直接在裏面拖拽也是可以的。
