unity3d_实现幻灯片效果2

上一篇使用的是静态方式进行的加载，采用的数据结构为 数组

该篇文章则是使用动态加载的方式实现：

this.objsOfRouses = Resources.LoadAll("images",typeof(Texture));

该方法会安排图片在文件在顺序进行加载。

如图：



加载顺序如下：



using UnityEngine;

using System.Collections;

public class imageAnimation : MonoBehaviour {

//

private Object[] objsOfRouses;

private Texture2D[] texturesLoaded;

private Material materialOfPanel;

private int frameCounter =0;

public float delayTime =0.5f;

private float currentTime=0.0f;

private float endTime =0.0f;

public GameObject dongWu;

void Awake()

{

//get the material of this panel

this.materialOfPanel = this.renderer.material;

}

// Use this for initialization

void Start ()

{

//set the starting time

currentTime =Time.time;//0.0s

//get images form the Resourse floder

//the return value is object

this.objsOfRouses = Resources.LoadAll("images",typeof(Texture));

int theLength =objsOfRouses.Length;

//put the images into material arrary

texturesLoaded =new Texture2D[theLength];

for (int i=0; i<theLength; i++)

{

this.texturesLoaded[i] =(Texture2D)this.objsOfRouses[i];

Debug.Log("the image'name is -->"+this.texturesLoaded[i].name);

}

}

// Update is called once per frame

void Update () {

changePic();

}

//

void changePic(){

endTime = Time.time;

float timeOffset = endTime - currentTime;

if (timeOffset>0.3){

if (this.frameCounter<this.objsOfRouses.Length){

this.materialOfPanel.mainTexture = texturesLoaded[frameCounter];

++frameCounter;

}else{

frameCounter=0;

this.materialOfPanel.mainTexture = texturesLoaded[frameCounter];

}

//when changge one image,get the new time

currentTime =Time.time;

}

}

}

最后效果如下：
