Sending packets

[LogicWin]

Hello, I've made this thread because I'm tired of the endless wow errors.

What I'm trying to do is to call the ClientService_SendPacket function.
As you will notice I'm using AutoIt for this.

I'm successfully called the function using:

 
  AsmAdd($asm, "mov ecx, [" & $base + $ClientConnection &"]")
  AsmAdd($Asm, "push " & $DataStore)
  AsmAdd($asm, "mov ebx, " & $base + $SendPacket)
  AsmAdd($asm, "call ebx")

I've have hooked the EndScene function, the hook allows me to run a code anytime of simple write to a flag.

I'm using the offsets:

$ClientConnection = 0x980558
$SendPacket = 0x87BF0        
$DataStore1 = 0x75A8A8

Now for the packet that i'm trying to send is a simple CMSG_CAST_SPELL packet.

Here's the datastore code/what i write to the address that I'm pushing.

_memorywrite($DataStore	    , $wow, $base + $DataStore1, "int"); ptrDataStore
_memorywrite($DataStore + 0x4 , $wow, $SpellPacket,"int")	; ptrPacketData
_memorywrite($DataStore + 0x8 , $wow, 0x0 ,"int")						; UnKnown1
_memorywrite($DataStore + 0xC , $wow, 0x100, "int")					; MayType; // 0x100 for normal, 0x300 for warden
_memorywrite($DataStore + 0x10, $wow, 0x5, "int")					; PacketLen
_memorywrite($DataStore + 0x14, $wow, 0x0, "int")						; UnKnown3

The spellpacket is build like this:

_memorywrite($SpellPacket, $wow, 0x5E4E, "int");OPCODE
_memorywrite($SpellPacket + 0x4, $wow, 0x01  , "byte")
_memorywrite($SpellPacket + 0x5, $wow, 0x1438, "ushort")

I've also tried to do like this:

_memorywrite( $Spellpacket, $wow, "4E 5E 00 00 1E 38 14" , "byte[12]")

And I've allocated the memory before i wrote of with this code:

$SpellPacket = _MemVirtualAllocEx( $wow[1], 0, 0x12, $MEM_COMMIT, $PAGE_EXECUTE_READWRITE )
$DataStore   = _MemVirtualAllocEx( $wow[1], 0, 0x18, $MEM_COMMIT, $PAGE_EXECUTE_READWRITE )

The issues I'm having is that wow gives me an error like:
The instruction at "0x774A8C19" referenced memory at "0x00000024".
The memory could not be "written".


So could any nice non-trolling person help me ?

This:

_memorywrite($DataStore + 0x10, $wow, 0x5, "int")

Should be this:

_memorywrite($DataStore + 0x10, $wow, 0x7, "int")

0x10 is packet length. Also, you need to fix up your spell packet structure, it's way wrong.


Edit: And stop using AutoIt. Damn.

[Aftiagouras]

Also, isnt ClientConnection 0x98056C ?

They point to the same place. It's always been like that.

This:

_memorywrite($DataStore + 0x10, $wow, 0x5, "int")

_memorywrite($DataStore + 0x10, $wow, 0x7, "int")

I've been using the spellpacket struct from the example @ http://www.ownedcore.com/forums/worl...endpacket.html ([SourceCode & Question] CastSpell by ID with SendPacket)

 
            SpellPacket spellPacket = new SpellPacket();
            spellPacket.OpCode = CMSG_CAST_SPELL;
            spellPacket.Count = 0;
            spellPacket.SpellID = (ushort)spellId;

[StructLayout(LayoutKind.Explicit, Size = 0x12)]
    public struct SpellPacket
    {
        [FieldOffset(0x0)]
        public int OpCode;
        [FieldOffset(0x4)]
        public byte Count;
        [FieldOffset(0x5)]
        public ushort SpellID;
    }

Is the structure wrong?

Yes.

    [StructLayout(LayoutKind.Explicit, Size = 0x18)]
    public struct Spell_Cast_AOE
    {
        [FieldOffset(0x0)] public uint OpCode; // 0x00005E4E
        [FieldOffset(0x4)] public byte Unknown1; // 0x00
        [FieldOffset(0x5)] public uint SpellID;
        [FieldOffset(0x9)] public uint Unknown2; // 0x00000000
        [FieldOffset(0xD)] public byte Unknown3; // 0x00
        [FieldOffset(0xE)] public uint SpellType; // 0x00000000 = AOE or cast on target
    }

You're gonna need to change it for cast on GUID and AOE on location and that, but I can't be bothered spoonfeeding anymore. What I've given you will work for both AOE and cast on target.

Edit: Don't use packets for casting unless your bot is clientless. Don't even bother.

[LogicWin]

Yes.

    [StructLayout(LayoutKind.Explicit, Size = 0x18)]
    public struct Spell_Cast_AOE
    {
        [FieldOffset(0x0)] public uint OpCode; // 0x00005E4E
        [FieldOffset(0x4)] public byte Unknown1; // 0x00
        [FieldOffset(0x5)] public uint SpellID;
        [FieldOffset(0x9)] public uint Unknown2; // 0x00000000
        [FieldOffset(0xD)] public byte Unknown3; // 0x00
        [FieldOffset(0xE)] public uint SpellType; // 0x00000000 = AOE or cast on target

Thanks, i appreciate that you're helping me

As for the record I'm not trying to create a clientless bot (too complicated), but I'm trying to create the teleport hack you guys have already done
