UGUI代码分析

Posted 2020-08-25

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

using System.IO;
using System.Xml;
public class dengl : MonoBehaviour
{
    public Image image_zc;
    public Text text_info;
    public Image image_ty_xxk;
    public Text text_ts;

    public InputField inputField_yhmm;
    public InputField inputField_qrmm;
    public InputField inputField_yhdh;
    public InputField inputField_yhqq;
    public InputField inputField_zh;
    public InputField inputField_mm;
    private string _xmlpath;//yong hu wen jian,_xmlpath = Application.dataPath + "/user.xml";
    //获得date路径只能在主线程赋值，不能再moonbehaviour构造函数赋值如上
   /* public void text()
    {
        ty_xxk("用户名或密码不能为空");
    }*/
    void Start()
    {
        _xmlpath = Application.dataPath + "/user.xml";
        if (!File.Exists(_xmlpath))
        {
            XmlDocument xmlDoc = new XmlDocument();//xin jian xml shi li
            XmlElement root = xmlDoc.CreateElement("Root");//gen jie dian , zui shang ceng jie dian
            xmlDoc.AppendChild(root);//zhi jie dian
            XmlElement user = xmlDoc.CreateElement("User");//yong hu jie dian
            user.SetAttribute("user_name", "Admin");

            user.SetAttribute("user_tel", "18373290290");
            user.SetAttribute("user_qq", "1780585054");
            root.AppendChild(user);
            xmlDoc.Save(_xmlpath);
            Debug.Log("xml creat success");
        }
    }
    public void Quit()
    {
#if UNITY_EDITOR
        UnityEditor.EditorApplication.isPlaying = false;
#else
        Application.Quit();
#endif
    }
    public void open_zc()
    {
        image_zc.gameObject.SetActive(true);
    }
