unity实现翻页效果
本文实例为大家分享了unity实现翻页效果的具体代码,供大家参考,具体内容如下
一、示意图
二、步骤
创建物体ToPanel;添加组件ScrollRect,
在下面创建一个空物体用来装需要移动的子物体,
创建一个Scrollbar;
三、代码
下面展示一些 内联代码片。
using UnityEngine; using System.Collections; using UnityEngine.UI; using System.Collections.Generic; public class SliderControl : MonoBehaviour { public Scrollbar m_Scrollbar; public ScrollRect m_ScrollRect; [Header("子物体的父物体")] public GameObject panel; [Header("移动到多少百分比图片切换")] //注释 [Range(0.1f, 0.9f)] //范围 public float banfenbi = 0.5f; [Header("是否限制一次只能切换一张图片")] public bool limit = false; private float mTargetValue; private bool mNeedMove = false; private const float SMOOTH_TIME = 0.2F; private float mMoveSpeed = 0f; private float child_Count; private float num1; private float var_Down; private List<float> num_list1 =new List<float>(); private List<float> num_list2 = new List<float>(); private List<float> num_list3 = new List<float>(); private int weizhi; //页数 void Start() { weizhi = 0; child_Count = panel.transform.childCount; num1 = 1 / (child_Count - 1); print("-----子物体数量------ " + child_Count + " " + num1); for (int i = 0; i < child_Count; i++) { float a = 0; num_list1.Add(a + num1 * i); float b = (a + num1 * i) + (num1 * banfenbi); num_list2.Add(b); float c = (a + num1 * i) + (num1 * (1-banfenbi)); num_list3.Add(c); print("---child_Count----- " + num_list1[i] + " " + num_list2[i]); } } public void OnPointer() { } public void OnPointerDown() { //print("---OnPointerDown----"); var_Down = m_Scrollbar.value; mNeedMove = false; } public void OnPointerUp() { //print("---OnPointerUp----"); //print("-----m_Scrollbar.value---- " + m_Scrollbar.value); for (int i = 0; i < child_Count; i++) { float num; if (var_Down- m_Scrollbar.value<0) { num = num_list2[i]; } else { num = num_list3[i]; } if (m_Scrollbar.value <= num) { if (limit) { if (i> weizhi) { weizhi = weizhi + 1; } else if (i == weizhi) { weizhi = i; } else { weizhi = weizhi - 1; } mTargetValue = num_list1[weizhi]; } else { mTargetValue = num_list1[i]; weizhi = i; //页数 } break; } } mNeedMove = true; mMoveSpeed = 0; } /// <summary> /// 直接跳转到指定页数 /// </summary> /// <param name="页数"></param> public void OnButtonClick(int value) { mTargetValue = num_list1[value]; if (mTargetValue<0) { mTargetValue = 0; } if (mTargetValue>1) { mTargetValue = 1; } weizhi = value; mNeedMove = true; } void Update() { if (mNeedMove) { if (Mathf.Abs(m_Scrollbar.value - mTargetValue) < 0.01f) { m_Scrollbar.value = mTargetValue; mNeedMove = false; MoveEnd(); return; } m_Scrollbar.value = Mathf.SmoothDamp(m_Scrollbar.value, mTargetValue, ref mMoveSpeed, SMOOTH_TIME); } } /// <summary> /// 移动完毕的回调 /// </summary> public void MoveEnd() { print("----- 移动完毕-----第几页--- "+ (weizhi+1)); } }
