The memory could not be "read".

[naa]

I finally got my Fish bot to work it can cast, detect the bobber and catch the fish - so fare so good.
It works flawless until wow terminates with an error:

The instruction at "0x007AF077" referenced memory at "0x00000017".
The memory could not be "read".

I assume this error has something to do with:

Shynd:
You have one thread and WoW has one (main) thread and they are both accessing WoW's TLS at the same time...

Does anyone know off a way to "pause" the main thread when i am executing my asm code?
I have been looking around the forum but I could not find any "deeper" explanation on how to do this.

Best Regards

SuspendThread?

Get a handle to the main thread suspend it and when your code has finished executing you resume it

I got the exact same error, but i dont know how to fix it.

Get a handle to the main thread suspend it and when your code has finished executing you resume it

I try to do it, but my bot works through CLRHost and have PID = PID Wow-64.exe. When i to do main thread suspend my bot suspend too.

public static ProcessThread GetUIThread()
{
if (pWow.MainWindowHandle == null) return null;
int id = GetWindowThreadProcessId(pWow.MainWindowHandle, IntPtr.Zero);
foreach (ProcessThread pt in pWow.Threads)
if (pt.Id == id) return pt;
return null;
}

public static void Suspend()
{
var pOpenThread = OpenThread(ThreadAccess.SUSPEND_RESUME, false, (uint)GetUIThread().Id);
Wow64SuspendThread(pOpenThread);

Oh... I forgot about access rights
I used

Process.GetProcessesByName("Wow-64")[0];

but it was necessary

const int PROCESS_WM_READ = 0x0010;
OpenProcess (PROCESS_WM_READ, false, Process.GetProcessesByName("Wow-64")[0].Id);

I still can't fix this error. I guess it occurs in GameObject.cs

        public static Int64 GetAddressGameObjectById(int gameObjectId)
        {
            // object list
            Int64 pObject = Memory.ReadAddress(IntPtr.Add(Memory.pBaseAddress, (int)Offsets.ClnObjMng.EntityList));
            if (pObject == 0) return 0;

            // first object
            pObject = Memory.ReadAddress(new IntPtr(pObject + (Int64)Offsets.ClnObjMng.FirstEntity));
            if (pObject == 0) return 0;

            int id = 0;

            while (pObject != 0 && (pObject & 1) == 0)
            {   
                id = Memory.ReadAddress32(new IntPtr(Memory.ReadAddress(new IntPtr(pObject + (Int64)Offsets.gObject.ID_first)) + (Int64)Offsets.gObject.ID_second));
                if (id == gameObjectId) return pObject;
                else // next object
                    pObject = Memory.ReadAddress(new IntPtr(pObject + (Int64)Offsets.ClnObjMng.NextEntity));

                if (pObject == 0) return 0;
            }
            return 0;
        }

        private static IntPtr handleProcess;

        public static void Initialization()
        {
            pBaseAddress = Process.GetProcessesByName("Wow-64")[0].MainModule.BaseAddress;

            handleProcess = OpenProcess(a, false, Process.GetProcessesByName("Wow-64")[0].Id);
        }

        public static Int64 ReadAddress(IntPtr address)
        {
            byte[] buffer = ReadBytes(address, sizeof(Int64));
            if (buffer == null) return 0;
            return BitConverter.ToInt64(buffer, 0);
        }

        public static byte[] ReadBytes(IntPtr address, Int64 length)
        {

            byte[] buffer = new byte[length];
            if (!ReadProcessMemory(handleProcess, address, buffer, length, out numRead)) return null;

            GUID = 0x50
        }

It is my regular fishing bot. He is work fine, but sometimes errors occur:

the instruction at "0x00007ff62e13e9a" referenced memory at "0xffffffffffffffff". The memory could not be "read".

Help me to fix it. Thanks in advance.
PS: this is my first serious program after "hello world" and i know my code is horrible. Sorry for my bad English.

Oh... it is my wrong CastSpell to causes an error
Spell.cs

    class Spell
    {
        private static byte[] unk20;
        private static Guid guid;

        public Spell()
        {
            unk20 = new byte[20];
            guid = new Guid(new byte[16]);
        }

        public void Cast(UInt64 spell_id)
        {
            Core.Delegates.CastSpell(spell_id, unk20, 0, guid);
        }
    }

Delegates.cs

class Delegates
    {
        public static CastSpellByIdDelegate CastSpell;
        
        public static void Initialization()
        {
            CastSpell = Memory.RegisterDelegate<CastSpellByIdDelegate>(IntPtr.Add(Memory.pBaseAddress, (int)Offsets.Delegates.CastSpell));
        }

        public delegate Int64 CastSpellByIdDelegate(UInt64 spell_id, byte[] a2, Int64 a3, Guid guid_d, Int64 a5 = 0, Int64 a6 = 0, Int64 a7 = 0, Int64 a8 = 0);
    }

Offsets.cs

        [Flags]
        public enum Delegates
        {
            CastSpell = 0x45E3A0
        }

without unk20 = byte [20] CastSpell do not called
