创建Slider
第一步：创建一个Canvas，右键选择UI，在选择Canvas
第二步：在Canvas下创建Slider，点击Canvas，右键选择UI，然后选择Slider
创建交互组件Sphere
点击Slider，右键选择3D Object，然后选择Sphere
然后移动Sphere的位置，将其移动到Slider子物体的第一行，成为Slider的第一个子物体
挂载交互脚本
在Slider上需要挂载 SliderControl 脚本，Sphere的移动位置根据自己的需求更改，代码如下：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;namespace UnityVolumeRendering
{
public class SliderControl : MonoBehaviour{
private Slider slider;private Transform sphere;private Removable removable;//public void SetValue(float value)//{
// slider = GetComponent<Slider>();// slider.value = value;// sphere = transform.GetChild(0);// sphere.localPosition = new Vector3(value * 140 - 70, 0, 0);//}// Use this for initializationvoid Start(){
slider = GetComponent<Slider>();Debug.Log(slider.value);sphere = transform.GetChild(0);Debug.Log(sphere.name);removable = sphere.GetComponent<Removable>();//sphere.localPosition = Vector3.zero;//slider.value = (float)0.5;}// Update is called once per framevoid Update(){
if (sphere.localPosition.x >= 70){
slider.value = (float)1;}else if (sphere.localPosition.x <= -70){
slider.value = 0;}else{
slider.value = (sphere.localPosition.x + 70) / 140;}if (!removable.moving){
if (sphere.localPosition.x >= 70){
sphere.localPosition = new Vector3(70, 0, 0);}else if (sphere.localPosition.x <= -150){
sphere.localPosition = new Vector3(-70, 0, 0);}else{
sphere.localPosition = new Vector3(sphere.localPosition.x, 0, 0);}}}}
}
在Sphere上挂载 Interactable 脚本和 Removable脚本，代码如下:
