写给美术大佬的脚本，还要继续改，github地址：TransEffect【github】
效果图如下：
Ver.1源码，针对3d Object：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class TransEffect : MonoBehaviour
{
public List<GoInfo> GoList;
public float varifySpeed = 0.5f;
public float aTime = 5f;//每个物体保持出现的时间
public float dTime = 5f;
private float minAlpha = 0.0f;
private float maxAlpha = .9f;
private float curAlpha = 1.0f;
private float nextAlpha = 0.0f;
private int i = 0;
public void OnEnable()
{
LoadGo();
}
// Use this for initialization
void Start()
{
//初始化全List隐形
foreach (GoInfo go in GoList)
{
Color c = go.rend.material.color;
c.a = 0;
go.rend.material.color = c;
}
}
// Update is called once per frame
public void Update()
{
Trans();
}
void LoadGo()
{
GoList = new List<GoInfo>();
GoList.Add(new GoInfo("Cylinder", 0, transform.Find("Cylinder").GetComponent<GameObject>(), transform.Find("Cylinder").GetComponent<MeshRenderer>()));
GoList.Add(new GoInfo("Cube", 1, transform.Find("Cube").GetComponent<GameObject>(), transform.Find("Cube").GetComponent<MeshRenderer>()));
GoList.Add(new GoInfo("Sphere", 2, transform.Find("Sphere").GetComponent<GameObject>(), transform.Find("Sphere").GetComponent<MeshRenderer>()));
GoList.Add(new GoInfo("Capsule", 3, transform.Find("Capsule").GetComponent<GameObject>(), transform.Find("Capsule").GetComponent<MeshRenderer>()));
}
private void Trans()
{
GoInfo go = GoList[i];
GoInfo nextgo;
Color c = go.rend.material.color;
Color nextc = go.rend.material.color;
if (i <= GoList.Count)
{
if (i == GoList.Count - 1)
{
nextgo = GoList[0];
}
else
{
nextgo = GoList[i + 1];
}
Debug.Log(nextAlpha);
Debug.Log(curAlpha);
if (Time.time < aTime)//当前物体保持显形
{
c.a = 1;
go.rend.material.color = c;
}
else if (Time.time >= aTime)
{
curAlpha += Time.deltaTime * varifySpeed * (-1);//当前物体逐渐消失
nextAlpha += Time.deltaTime * varifySpeed;//下一个物体逐渐现形
if (curAlpha <= minAlpha)//当前物体渐变到不透明时
{
c.a = 0;//设置当前obj保持透明
go.rend.material.color = c;
i++;
//设置数据为下一物体做准备
curAlpha = 1;
nextAlpha = 0;
}
else//当前物体逐渐透明，下一物体逐渐现形
{
curAlpha = Mathf.Clamp(curAlpha, minAlpha, maxAlpha);
nextAlpha = Mathf.Clamp(nextAlpha, minAlpha, maxAlpha);
c.a = curAlpha;
nextc.a = nextAlpha;
go.rend.material.color = c;
nextgo.rend.material.color = nextc;
}
if (curAlpha >= maxAlpha)//下一物体完全显形
{
Debug.Log(nextAlpha);
Debug.Log(curAlpha);
aTime = Time.time + dTime; //设置新一轮时间限制
Debug.Log(aTime);
}
}
}
else
{
i = 0;
}
}
}
[System.Serializable]
public class GoInfo
{
public string ID;
public int index;
public MeshRenderer rend;
public GameObject[] obj;
public GameObject curObj;
private Color co;
public GoInfo(string id0, int index0, GameObject obj0, MeshRenderer rend0)
{
ID = id0;
index = index0;
curObj = obj0;
rend = rend0;
}
}
创建物体：
写完才发现是要用在UI Image上的...不过其实差别也不大，还略简单点。
Ver.2源码，针对UI Image:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class TransEffect : MonoBehaviour
{
public Transform lib;
public List<GoInfo> GoList;
public float varifySpeed = 0.5f;
public float aTime = 5f;//每个物体保持出现的时间
public float dTime = 5f;//第一张图片第一轮循环时出现时间
private float minAlpha = 0.0f;
private float maxAlpha = .9f;
private float curAlpha = 1.0f;
private float nextAlpha = 0.0f;
private int i = 0;
public void OnEnable()
{
LoadGo();
}
// Use this for initialization
void Start()
{
//初始化全List隐形
foreach (GoInfo go in GoList)
{
Color c = go.curImg.color;
c.a = 0;
go.curImg.color = c;
}
}
// Update is called once per frame
public void Update()
{
Trans();
}
void LoadGo()
{
//添加图片列表
GoList = new List<GoInfo>();
for (int i = 0; i < lib.childCount; i++) {
GoList.Add(new GoInfo(lib.GetChild(i).name.ToString(),lib.transform.GetChild(i).GetComponent<Image>()));
}
Debug.Log(GoList.Count);
}
private void Trans()
{
Debug.Log(i);
GoInfo go;
GoInfo nextgo;
if (i >= GoList.Count - 1)
{
go = GoList[i];
nextgo = GoList[0];
}
else
{
go = GoList[i];
nextgo = GoList[i + 1];
}
Color c = go.curImg.color;
Color nextc = go.curImg.color;
if (Time.time < aTime)//当前物体保持显形
{
c.a = 1;
go.curImg.color = c;
}
else if (Time.time >= aTime)
{
curAlpha += Time.deltaTime * varifySpeed * (-1);//当前物体逐渐消失
nextAlpha += Time.deltaTime * varifySpeed;//下一个物体逐渐现形
if (curAlpha <= minAlpha)//当前物体渐变到不透明时
{
c.a = 0;//设置当前obj保持透明
go.curImg.color = c;
if (i == GoList.Count - 1)
i = -1;
i++;
//设置数据为下一物体做准备
curAlpha = 1;
nextAlpha = 0;
}
else//当前物体逐渐透明，下一物体逐渐现形
{
curAlpha = Mathf.Clamp(curAlpha, minAlpha, maxAlpha);
nextAlpha = Mathf.Clamp(nextAlpha, minAlpha, maxAlpha);
c.a = curAlpha;
nextc.a = nextAlpha;
go.curImg.color = c;
nextgo.curImg.color = nextc;
}
if (curAlpha >= maxAlpha)//下一物体完全显形
{
aTime = Time.time + dTime; //设置新一轮时间限制
}
}
}
}
[System.Serializable]
public class GoInfo
{
public string ID;
public Image[] imgList;
public Image curImg;
private Color co;
public GoInfo(string id0,Image img)
{
ID = id0;
curImg = img;
}
}
直接把存放图片子物体的父物体拖到Lib变量中，再调整所需渐变速度和显示时间即可。
设置如下：
