根据滑块的值更改 UI 中的图像

Question

当滑块的值改变时，我试图在 UI 中改变图像，现在当我移动滑块时什么都没有发生，这是我的代码：

public class ImagesSlider : MonoBehaviour
{
// Start is called before the first frame update

public Sprite sprite1;
public Sprite sprite2;
public Sprite sprite3;
public Sprite sprite4;
public Sprite sprite5;
public Sprite sprite6;
public Sprite sprite7;
public Sprite sprite8;
public Sprite sprite9;
public Sprite sprite10;
public Sprite sprite11;

public Slider imageslider;


void Start()
{
    gameObject.GetComponent<Image>();
}

void Update()
{
    ChangeImage();
}

// Update is called once per frame
void ChangeImage()
{
    if (imageslider.value == 1.0f)
    {
        gameObject.GetComponent<Image>().sprite = sprite1;
    }

    if (imageslider.value == 2.0f)
    {
        gameObject.GetComponent<Image>().sprite = sprite2;
    }
}

非常感谢您的帮助

如果您的滑块的最大值为 1，您必须检查 0-1 之间的值，因为它是浮动的，您需要大于或小于您的条件。

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

public class MySlider : MonoBehaviour
{
    // Start is called before the first frame update

    public Sprite sprite1;
    public Sprite sprite2;
    public Sprite sprite3;
    public Sprite sprite4;
    public Sprite sprite5;
    public Sprite sprite6;
    public Sprite sprite7;
    public Sprite sprite8;
    public Sprite sprite9;
    public Sprite sprite10;
    public Sprite sprite11;

    public Slider imageslider;
    public Image img;


    void Start()
    {
        img = gameObject.GetComponent<Image>();
    }

    void Update()
    {
        ChangeImage();
    }

    // Update is called once per frame
    void ChangeImage()
    {
        if (imageslider.value <= .1f)
        {
            img.sprite = sprite1;
        }

        if (imageslider.value <= .2f && imageslider.value >= .1f)
        {
            img.sprite = sprite2;
        }
    }
}
