Reading pointers with offsets doesn´t work..

Hey.

I have this class for reading from memory:

Code:

using System;
using System.Text;
using System.Runtime.InteropServices;
using System.Diagnostics;

namespace Game.Memory
{
    class Memory
    {
        [DllImport("kernel32.dll")]
        static extern IntPtr OpenProcess(UInt32 dwDesiredAccess, Boolean bInheritHandle, UInt32 dwProcessId);
        [DllImport("kernel32.dll")]

        static extern bool ReadProcessMemory(IntPtr hProcess, IntPtr lpBaseAddress,
        byte[] lpBuffer, UIntPtr nSize, uint lpNumberOfBytesWritten);

        [DllImport("Kernel32.dll")]
        public static extern bool ReadProcessMemory(IntPtr handle, int address, byte[] bytes, int nsize, ref int op);

        [DllImport("Kernel32.dll")]
        public static extern bool WriteProcessMemory(IntPtr hwind, int Address, byte[] bytes, int nsize, out int output);

        [DllImport("Kernel32.dll")]
        public static extern IntPtr OpenProcess(int Token, bool inheritH, int ProcID);


        IntPtr Handle;

        public Memory(int sprocess)
        {
            Process Processes = Process.GetProcessById(sprocess);
       
            Handle = OpenProcess(0x10, false, (uint)Processes.Id);
          
        }






        public string ReadString(int address, int nsize)
        {
            int Outp = 0;
            byte[] BytesToRead = new byte[nsize];

            ReadProcessMemory(Handle, address, BytesToRead, BytesToRead.Length, ref Outp);

            return System.Text.Encoding.ASCII.GetString(BytesToRead);
        }


        public int ReadInt(int address, int nsize)
        {
            int OP = 0;
            byte[] BytesToRead = new byte[nsize];
            ReadProcessMemory(Handle, address, BytesToRead, BytesToRead.Length, ref OP);

            return BitConverter.ToInt32(BytesToRead, 0);
        }

        public float ReadFloat(int address, int nsize)
        {
            int OP = 0;
            byte[] BytesToRead = new byte[nsize];
            ReadProcessMemory(Handle, address, BytesToRead, BytesToRead.Length, ref OP);

            return (float)BitConverter.ToSingle(BytesToRead, 0);
        }



        public int ReadIntPtr(int address, int[] offsets, int Size = 4)
        {
            int MainAddress = address;
            for (int i = 0; i < offsets.Length; i++)
            {
                MainAddress = ReadInt(MainAddress, Size) + offsets[i];
            }
            return MainAddress;
        }


      

        public float ReadFloatPtr( int address, int[] offsets, int Size = 4)
        {
            int AddressToWriteToo = ReadIntPtr(address, offsets);

            float Data = ReadFloat(AddressToWriteToo, 4);

            return Data;
        }

       



        public string ReadStringPtr(int address, int[] offsets, int ExspectedLength)
        {
            int AddressToRead = ReadIntPtr(address, offsets);

            string TheString = ReadString(AddressToRead, ExspectedLength);

            return TheString;
        }


    }
}

Now I have some pointer with differen types. Some are texts, some are numbers.

I already did it to read my Charactername (Pointer + Offset):

Code:

  int pID= 13700;
             int PlayerPointer = 0x16c0c18;
             int GameTimePtr = 0x16c3cbc;
             int GoldAddresse = 0x16c3fdc;

             Memory mem = new Memory(LoLID);
             Process GameProcess = Process.GetProcessById(pID);
             IntPtr BaseAddress = GameProcess.MainModule.BaseAddress;

             //Name
             string Name = mem.ReadStringPtr( BaseAddress.ToInt32() + PlayerPointer, new int[] { 0x20}, 10);
             textBox1.Text = Name;

This works.

Also I got the healthreader working:

Code:

int MaxHealth = (int)mem.ReadFloatPtr(BaseAddress.ToInt32() + PlayerPointer, new int[] { 0x660 });

But now i have some strange problems.
The first is another pointer (Value is 1-20).
I tried to get my Level with this:

Code:

int Level = mem.ReadIntPtr(BaseAddress.ToInt32() + PlayerPointer, new int[] { 0x3C5C });

The offset is right, but I get this:
1,401298E-45

Another problem is another number pointer with 2 offsets. Tried this:

Code:

lbGold.Text = mem.ReadFloatPtr(BaseAddress.ToInt32() + GoldAddresse, new int[] { 0x54, 0x44 }).ToString();

And I see the value is changing (right) but the value is 100% wrong. I get:
2,397622E-42

So where is the problem with these 2 reading codes? The offsets + addresses are correct.

Thank you

How about debugging your software?
