Unity中UGUI脚本添加Button按钮事件

在场景中添加UGUI的Button按钮

然后在在脚本中写添加的事件

//声明UI
using UnityEngine.UI;
//声明场景的跳转
using UnityEngine.SceneManagement;
    //战士模型  弓箭手模型
    GameObject m_Warrior, m_Archer;
    //战士按钮 弓箭手按钮 创建角色按钮
    Button soldierBtn, ancherBtn, createBtn;
    //输入框
    InputField inputField;
    Transform root;

在Start (){}中写获取按钮组件

void Start () {
        //获得脚本挂的Transform
        root = this.transform;
        //获取场景中按钮的引用
        soldierBtn = root.FindChild("WarriorButton").GetComponent();
        ancherBtn = root.FindChild("ArcherButton" ).GetComponent();
        createBtn = root.FindChild("Begin").GetComponent();
        //获取场景中的输入框
        inputField = root.FindChild("NameInput").GetComponent();
        //注册点击事件
        soldierBtn.onClick.AddListener(OnSoldierClick);
        ancherBtn.onClick.AddListener(OnAncherClick);
        createBtn.onClick.AddListener(OnCreateClick);
    }
     void OnSoldierClick()
    {
        //如果弓箭手模型不为空
        if (m_Archer != null)
        {
            //弓箭手模型隐藏
            m_Archer.SetActive(false);
        }
        //剑士模型为空时
        if (m_Warrior == null)
        {
            //获得模型所在的位置
            GameObject Warrior = Resources.Load("Prefabs/Character/Warrior") as GameObject;
            //创建模型
            m_Warrior = Instantiate(Warrior) as GameObject;
            //设置相应的父节点，位置，大小
            m_Warrior.transform.SetParent(root);
            m_Warrior.transform.localPosition = new Vector3(128f, -28f, -412f);
            m_Warrior.transform.localScale = new Vector3(90, 90, 90); 
        }
        else
        {
            //剑士模型显示
            m_Warrior.SetActive(true);
        }
    }
    void OnAncherClick()
    {
        //剑士模型不为空
        if (m_Warrior != null)
            {
                //剑士模型隐藏
                m_Warrior.SetActive(false);
            }
        //弓箭手模型为空
        if (m_Archer == null)
        {
            //获取弓箭手模型位置
            GameObject Archer = Resources.Load("Prefabs/Character/Archer") as GameObject;
            //创建弓箭手模型
            m_Archer = Instantiate(Archer) as GameObject;
            //设置相应的父节点，位置，大小
            m_Archer.transform.SetParent(root);
            m_Archer.transform.localPosition = new Vector3(128f, -28f, -412f);
            m_Archer.transform.localScale = new Vector3(90, 90, 90);
        }
        else
        {
            //弓箭手模型显示
            m_Archer.SetActive(true);
        }
    }
    void OnCreateClick()
    {
        //模型和名字为空时
        if (soldierBtn == null && ancherBtn == null || inputField.text == "")
        {
            print("错误");
            return;
        }
        else
        {
            //跳转场景
            IGameManagerNew.Instance.LoadSence("Scene_Forest");
        }
    }
