XOR+ random Anticheat

Hello, i want to know if is posible prevent Cheat Engine with a random seed + xor encryption:

 using System;
 using UnityEngine;
 
 namespace BizarreAntiCheat{
     [Serializable]
     public struct oInt : IEquatable<oInt>, IFormattable{
         private static System.Random Random=new System.Random();
         [SerializeField]private int key;
         [SerializeField]private int val;
         [SerializeField]private int va2;
 
         private oInt(int value){
             key=Random.Next(int.MinValue, int.MaxValue);
             val=Encrypt(key,value);
             va2=value;
         }
 
         public bool IsCheating(){return Encrypt(key,va2)==val?false:true;}
         private int Get(){
             if(IsCheating())
                 Debug.Log("You got bac banned");
             return Decrypt(key,val);
         }
 
         public static int Encrypt(int k,int v){return k^v;}
         public static int Decrypt(int k,int v){return k^v;}
 
         public static implicit operator oInt(int value){Debug.Log("random");return new oInt(value);}
         public static implicit operator int(oInt value){return value.Get();}
         public override string ToString(){return Get().ToString();}
         public            string ToString(string format){return Get().ToString(format);}
         public            string ToString(IFormatProvider provider){return Get().ToString(provider);}
         public            string ToString(string format, IFormatProvider provider){return Get().ToString(format, provider);}
         public override int GetHashCode(){return Get().GetHashCode();}
         public override bool Equals(object obj){return !(obj is oInt)?false:Equals((oInt)obj);}
         public            bool Equals(oInt obj){
             if(key==obj.key)
                 return val==obj.val;
             return Decrypt(key,val)==Decrypt(obj.key, obj.val);
         }
     }
 }`

Is the line #13 (Random.Range) a good idea or is unnecesary? Can be undetectable by Cheat Engine with no random number?

         private static int KeyDefinedByUser;
 
         private oInt(int value){
             key=KeyDefinedByUser;
             val=Encrypt(KeyDefinedByUser,value);
             va2=value;
         }

Sorry my english.
