一、字串引用GameObject變數

using UnityEngine;
using System;
using System.Linq.Expressions;

public class Test : MonoBehaviour
{
    public GameObject camerrr;
    void Start()
    {
        GameObject go = this.GetType().GetField("camerrr").GetValue(this) as GameObject;
        Debug.Log(go.transform.position); //此時的go即為inspector面板中賦值的GameObject
    }
}
 

public class Test : MonoBehaviour
{
    public GameObject camerrr;
    void Start()
    {
        string propertyName = PropertySupport.ExtractPropertyName(() => this.camerrr);
         Debug.Log(propertyName);//輸出 camerrr
    }
    //獲取變數字串方法
    public static class PropertySupport
    {
        public static string ExtractPropertyName<T>(Expression<Func<T>> propertyExpression)
        {
            MemberExpression memberExpression = propertyExpression.Body as MemberExpression;
            return memberExpression.Member.Name;
        }
    }
}
 

using UnityEngine;
using System;
using System.Linq.Expressions;

public class Test : MonoBehaviour {
    public GameObject camerrr;
    void Start () {
        string propertyName = PropertySupport.ExtractPropertyName(() => this.camerrr);
        GameObject go = this.GetType().GetField(propertyName).GetValue(this) as GameObject;
        Debug.Log(go.transform.position);
    }
    //獲取方法
    public static class PropertySupport
    {
        public static string ExtractPropertyName<T>(Expression<Func<T>> propertyExpression)
        {
            MemberExpression memberExpression = propertyExpression.Body as MemberExpression;
            return memberExpression.Member.Name;
        }
    }
}
