Click to Move - Explained

[Azzie2k8]

I have been trying to use this for a couple of days now and have encountered a problem.
I honestly don't want to open a new thread for this since this seems to fit in here.

Whenever I try to use this function I get the "Tried to read/write protected Memory. Memory is corrupt." exception.

        [UnmanagedFunctionPointer(CallingConvention.ThisCall)]
        public delegate bool CGPlayer_C__ClickToMove(IntPtr pObject, int ClickToMoveType, IntPtr pGuid, IntPtr pClickPosition, float Precision);
        public static CGPlayer_C__ClickToMove _ClickToMove;

[code]
function looks like this

        public static void ClickToMove(Helper.WoWClickToMoveType Type, ulong tGuid, Helper.WoWPoint tPosition, float Precision)
        {
            if (ObjectManager.Me.ObjectPointer == IntPtr.Zero)
                throw new NullReferenceException("ClickToMove invoked from an invalid Object");

            if (Hooks._ClickToMove == null)
                Hooks._ClickToMove = EntryPoint.Memory.RegisterDelegate<Hooks.CGPlayer_C__ClickToMove>(Statics.ClickToMoveAdress);

            IntPtr pGuid = IntPtr.Zero;
            IntPtr pPosition = IntPtr.Zero;

            try
            {
                if (tGuid != 0)
                {
                    pGuid = Marshal.AllocHGlobal(0x4 * 2);
                    EntryPoint.Memory.Write<ulong>(pGuid, tGuid);
                }

                if (!(tPosition.X == 0 && tPosition.Y == 0 && tPosition.Z == 0))
                {
                    pPosition = Marshal.AllocHGlobal(0x4 * 3);
                    EntryPoint.Memory.Write<float>((uint)pPosition + 0x0, tPosition.X);
                    EntryPoint.Memory.Write<float>((uint)pPosition + 0x4, tPosition.Y);
                    EntryPoint.Memory.Write<float>((uint)pPosition + 0x8, tPosition.Z);
                }

                Hooks._ClickToMove(ObjectManager.Me.ObjectPointer, (int)Type, pGuid, pPosition, Precision);
            }
            finally
            {
                if (pGuid != IntPtr.Zero)
                {
                    Marshal.FreeHGlobal(pGuid);
                }
                if (pPosition != IntPtr.Zero)
                {
                    Marshal.FreeHGlobal(pPosition);
                }
            }
        }

and I am using 0x006BA610 as Address.

by registering it like this

 _ClickToMove = EntryPoint.Memory.RegisterDelegate<CGPlayer_C__ClickToMove>((uint)Statics.ClickToMoveAdress);

I have been trying with some help to fix this issue but it stays the same all the time.
My Dostring Hook works so I assume since it works kinda the same way that my ClickToMove Hook works too. I also checked the ObjPtr which is correct too.

If anyone sees where I am going wrong please let me know.

I am also ready to get flamed

If you're in process you can properly set up the delegate (since it looks like you are, as you're using my library)

[UnmanagedFunctionPointer(CallingConvention.ThisCall)]
        private delegate byte CPlayerC_ClickToMove(IntPtr thisObj, int clickType, ref ulong guid, ref Point clickPos, float precision);

Yes I am using your library.

With the help of Robske I found out that it will only throw the exception if the TargetGuid passed is 0. Atm I am by-passing this by passing my own guid if I am just walking somewhere.

Pass a pointer to a ulong of 0, don't just pass 0.
