1.canvas，screen模式和world模式区别：screen的绑定摄像机与canvas相对位置不会改变不可改变canvas，world模式下有个event camera相对位置可改变，canvas可改变，canvas就相当于一个3D物体。sorting，order layer规定canvas优先级。
2.富文本支持html标签。
3.控制image fill
public class imagetype : MonoBehaviour {
public Image imagel;
public float i = 0.0f;
}
void Update () {
imagel.type = Image.Type.Filled;
imagel.fillMethod = Image.FillMethod.Radial360;
imagel.fillAmount = i;
if (i >= 1.0f) { i = 0.0f; }
i = i + 0.002f;
}
4.控制按钮
public class button : MonoBehaviour {
public Image image_sp;
public Text text_sp;
public Text text_btn;
public void open_close(){
if(text_btn.text == "打开图片"){
image_sp.gameObject.SetActive(true);
text_btn.text = "关闭图片";
text_sp.text = "无敌是多么寂寞";
}
else {
image_sp.gameObject.SetActive(false);
text_btn.text = "打开图片";
text_sp.text = "无敌？";
}
5.控制按钮，内建图片数组
public class button1 : MonoBehaviour {
public Image image_sp;
public Sprite[] image_sps;
private string select_name;
private int i;
public void sp()
{
select_name = EventSystem.current.currentSelectedGameObject.name;
if (select_name == "Button_left")
{
if (i <= 0) { i = image_sps.Length - 1; }
image_sp.overrideSprite = image_sps[--i];
}
else
{
if (i >= image_sps.Length - 1) { i = 0; }
image_sp.overrideSprite = image_sps[++i];
}
6.锚点必须在他的父对象内设置，如果没有父对象或者父对象没有锚点那么他就没有锚点。
7.InputField。Navigation自动匹配发布导航信息。
public class input_js : MonoBehaviour {
public Text text_jg;
public InputField input1;
public InputField input2;
public InputField input_to;
public GameObject panel_tc;
public void js(){
text_jg.text = (int.Parse(input1.text) - int.Parse(input2.text)).ToString();
}
public void tc()
{
panel_tc.SetActive(true);
}
public void yes()
{
text_jg.text = input_to.text;
panel_tc.SetActive(false);
}
public void no()
{
panel_tc.SetActive(false);
}
}
8.xml本地存储登录案例
Application.OpenURL("http://wwww.4399.com");
这里的涉及到未包含的库，需要引入一个dll文件，参考思考问题博客。登录窗口脚本，xml文件的创建。dll的引用。var隐式类型。
using System.IO;
using System.Xml;
public class dengl : MonoBehaviour

}
9.Toggle。 GameObject.Find 是不是不能找到一个物体的子物体？bg1,2,3,4是bg的子物体。
public class qh_bj : MonoBehaviour {
private GameObject root;
private GameObject oldobj = null;
private GameObject newobj = null;
// Use this for initialization
void Start () {
root = GameObject.Find("bg");
oldobj = root.transform.Find("bg1").gameObject;
Debug.Log(oldobj.name);
}
public void print_name()
{
string s = EventSystem.current.currentSelectedGameObject.name;
//Debug.log(str);
switch (s)
{
case "Toggle1":
newobj = root.transform.Find("bg1").gameObject;
newobj.SetActive(true);
oldobj.SetActive(false);
oldobj = newobj;
oldobj.SetActive(true);
break;
case "Toggle2":
newobj = root.transform.Find("bg2").gameObject;
newobj.SetActive(true);
oldobj.SetActive(false);
oldobj = newobj;
oldobj.SetActive(true);
break;
case "Toggle3":
newobj = root.transform.Find("bg3").gameObject;
newobj.SetActive(true);
oldobj.SetActive(false);
oldobj = newobj;
oldobj.SetActive(true);
break;
case "Toggle4":
newobj = root.transform.Find("bg4").gameObject;
newobj.SetActive(true);
oldobj.SetActive(false);
oldobj = newobj;
oldobj.SetActive(true);
break;
}
}
10.Toggle2 Find子物体
public class qh_wz : MonoBehaviour {
public Text text1;
public void t_event2(bool xz)
{
string tt = transform.FindChild("Label").GetComponent<Text>().text;
bool bl = GetComponent<Toggle>().isOn;
if (bl)
{
text1.text = text1.text + tt + "真" + "\n";
}else
{
text1.text = text1.text + tt + "假" + "\n";
}
}
FindChild改成Find也是可以的。
11.slider模拟血条
public class xuetiao : MonoBehaviour {
public Text text1;
public Slider slider2;
public void dis_slider_value()
{
text1.text = slider2.value.ToString();
}
public void zx()
{
slider2.value = slider2.value + 60;
}
public void jx()
{
slider2.value = slider2.value - 60;
}
12.slider，建立materia彩纸detail动态纹理 ，纹理偏移， Time.time是从程序开始执行到现在的时间，，，，deltaTime=0.0166，要加Position As SUV1组件
public class mov : MonoBehaviour {
public Light l1;
Material mOriginal;
Image mSprite;
public Vector2 scrollPerSecond = Vector2.zero;
public AudioSource myAudio;
public Text text_ln;
public Text text_vn;
// Use this for initialization
void Start () {
mSprite = GetComponent<Image>();
mOriginal = mSprite.material;
}
// Update is called once per frame
void Update () {
if (mOriginal != null){
Texture tex = mOriginal.GetTexture("_DetailTex");
if (tex != null)
{
mOriginal.SetTextureOffset("_DetailTex", scrollPerSecond * Time.time);
}
}
}
public void light1(float v)
{
l1.intensity = v;
text_ln.text = v.ToString();
}
public void vol(float v)
{
myAudio.volume = v;
text_vn.text = v.ToString();
}
13.scrollbar。编写一个带浮点型参数的函数，scrollar传递过去
GetComponent.<RectTransform>().localPosition = new Vector3(1f,1f,1f); GetComponent.<RectTransform>().localScale = new Vector3(1f,1f,1f);
14.Layout。child Force Expand与Flexible功能一样，文字和image自带适宜尺寸，raw image没有适宜尺寸。
15.模拟下拉组合框，迭代访问子物体
public class list : MonoBehaviour {
public GameObject list_close;
public InputField field1;
public Text text_dis;
// Use this for initialization
void Start () {
}
public void combox()
{
for(int i = 0; i < this.transform.childCount; i++)
{
field1.text = this.transform.GetChild(i).GetComponent<Text>().text;
text_dis.text = "你选择的是" + field1.text;
}
}
public void combox_close()
{
list_close.SetActive(false);
GameObject.Find("Toggle").GetComponent<Toggle>().isOn = false;
}
}
16.事件类！！！！！！！！！！！！！！！！！！！！！！！！！！接口
public class scroll : MonoBehaviour,IMoveHandler,IScrollHandler{
//默认是事件 是Image 如果鼠标点击了别处 那么事件就变了 就不能控制Image了
public Text text1;
public Camera maincamera;

{
f1 = f1 + eventData.scrollDelta.y * 3f;
maincamera.fieldOfView = Mathf.Clamp(f1, 1f, 179f);
text1.text = eventData.scrollDelta.ToString();
}
}
public class select : MonoBehaviour,ISelectHandler,ICancelHandler,IPointerDownHandler,IUpdateSelectedHandler,IDeselectHandler,ISubmitHandler{
//物体身上必须有脚本才能 实现事件功能
public Text text1;
private int i = 0;
public void OnSelect(BaseEventData eventData)
{
//text1.text = "我被选择了" + eventData.selectedObject;
}
public void OnCancel(BaseEventData eventData)//按esc取消事件
{
text1.text = "我被取消了选择" + eventData.selectedObject;
}
public void OnPointerDown(PointerEventData eventData)
{
text1.text = eventData.position.ToString();//position属性可通过查看PointerEventData/Variables改为其他属性

public void OnUpdateSelected(BaseEventData eventData)
{
++i;
//text1.text = "我被选择了" + eventData.selectedObject + "OnUpdateSelected" + i;

}
public void OnSubmit(BaseEventData eventData)

void Update () {
}
public void OnBeginDrag(PointerEventData eventData)
{
Debug.Log("OnBeginDrag:拖动开始事件：" + eventData.position);
m_DraggingIcon = new GameObject("icon");
m_DraggingIcon.transform.SetParent(cavs.transform, false);
m_DraggingIcon.transform.SetAsLastSibling();

{
Debug.Log("OnEndDrag:拖动结束事件" + eventData.position);
if (m_DraggingIcon != null)
{
Destroy(m_DraggingIcon);

粘贴复制的装备
public class drop_zb : MonoBehaviour,IDropHandler,IPointerEnterHandler,IPointerExitHandler{
public void OnDrop(PointerEventData data)
{
var originalObj = data.pointerDrag;
if (originalObj == null)
return;

选择事件提交事件

}
public void OnSubmit(BaseEventData eventData)
{
text1.text = "我被提交了" + eventData.selectedObject + "Onsubmit";
}
}
代码生成按钮物体并添加监听器
public class dtai_event : MonoBehaviour {
public Canvas cavs;
public Text text1;
public Font f1;
public int counter;
// Use this for initialization
void Start () {
counter = 0;
}
// Update is called once per frame

tt.transform.SetParent(m_DraggingIcon.transform, false);
tt.transform.SetAsLastSibling();
btn.onClick.AddListener(delegate ()
{
this.btn1click(m_DraggingIcon);
});// 匿名方法 添加 监听函数
}
public void btn1click(GameObject e)
{
text1.text = "你点击了" + e.name;
}
delegate定义委托 订阅事件 类里定义一个类！！！！！！！！！！！！！！！！！public class类public viod函数
public class wtuo_dyue : MonoBehaviour {
public Text text1;
private int counter;
private string disstr = "111111111111111111111111111";

//1 定义一个委托
public delegate void timearriveEventHandler(string str);
//时间到达类

Timer_arrived.Start_time();
}
//4 编写事件处理方法
public void WriteText(string s)

public InputField InputField_content;
//定义要发布的新闻类 参数
public class news_args
{
public string news_title = "news_title";

}
接收或者取消订阅新闻
public class dingyue_wt : MonoBehaviour {

17.UGUI界面案例，给载有动画组件的的物体添加脚本，可以给动画针添加事件脚本
using UnityEngine.SceneManagement;
