使用滑塊統一移動預制件

Question

我正在使用此代碼來實例化對象，當我單擊其中一個對象並更改滑塊時，它會獲取滑塊值並旋轉。現在我想沿y軸移動單擊的對象我嘗試使用相同的代碼，但它沒有我的工作錯在了什么？

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class dynamicmovement : MonoBehaviour
{
    public GameObject cubePrefab;
    public Slider cubeSlider;
    public Button instantiateButton;
    public Button instantiateButton2;

    public Slider cubeSlider2;


    public float speed = 0f;
    public float pos = 0f;
    public GameObject mcamera;
    Vector3 cposition;

    private Transform currentObjectToDrag = null;

    // Use this for initialization
    void Start()
    {
        //Set Slider Values
        cubeSlider.minValue = 0f;
        cubeSlider.maxValue = 360f;
        cubeSlider.value = 0f;

        cubeSlider2.minValue = 0f;
        cubeSlider2.maxValue = 360f;
        cubeSlider2.value = 0f;


    }

    // Update is called once per frame
    void Update()
    {

            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            if (Physics.Raycast(ray, out hit, 1000.0f))
            {
                GameObject objHit = hit.collider.gameObject;
                Debug.Log("We Clicked on : " + objHit.name);

                //Check if this is cube
                if (objHit.CompareTag("Cube"))
                {
                    Debug.Log("Cube selected. You can now drag the Cube with the Slider!");
                    //Change the current GameObject to drag
                    currentObjectToDrag = objHit.transform;

        cubePrefab.transform.position = cposition;
        //mcamera.transform.position = new Vector3(+10, +10, +10);


        //transform.position = new Vector3(351, -36, 60);
        Instantiate(cubePrefab, cubePrefab.transform.position, transform.rotation);






       //Instantiate(cubePrefab, new Vector3(519f, -41f, 170f), Quaternion.identity);

Answer 1

您不能定義兩次函數（ OnEnable和OnDisable ）。 您可以在一個OnEnable和OnDisable函數中注冊cubeSlider和cubeSlider事件。

public class dynamicmovement : MonoBehaviour
{

    public GameObject cubePrefab;
    public Slider cubeSlider;
    public Button instantiateButton;
    public Button instantiateButton2;

    public Slider cubeSlider2;


    public float speed = 0f;
    public float pos = 0f;
    public GameObject mcamera;
    Vector3 cposition;

    private Transform currentObjectToDrag = null;

    // Use this for initialization
    void Start()
    {
        //Set Slider Values
        cubeSlider.minValue = 0f;
        cubeSlider.maxValue = 360f;
        cubeSlider.value = 0f;

        cubeSlider2.minValue = 0f;
        cubeSlider2.maxValue = 360f;
        cubeSlider2.value = 0f;


    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetMouseButtonDown(0))
        {
            RaycastHit hit;
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            if (Physics.Raycast(ray, out hit, 1000.0f))
            {
                GameObject objHit = hit.collider.gameObject;
                Debug.Log("We Clicked on : " + objHit.name);

                //Check if this is cube
                if (objHit.CompareTag("Cube"))
                {
                    Debug.Log("Cube selected. You can now drag the Cube with the Slider!");
                    //Change the current GameObject to drag
                    currentObjectToDrag = objHit.transform;
                }
            }

        cposition = new Vector3(mcamera.transform.position.x + 80, mcamera.transform.position.y - 2, mcamera.transform.position.z + 10);

        cubePrefab.transform.position = cposition;
        //mcamera.transform.position = new Vector3(+10, +10, +10);


        //transform.position = new Vector3(351, -36, 60);
        Instantiate(cubePrefab, cubePrefab.transform.position, transform.rotation);






        //Instantiate(cubePrefab, new Vector3(519f, -41f, 170f), Quaternion.identity);

            Debug.Log("Position changed!");
        }
    }

    void sliderCallBack2(float value)
