AOE Target Spells (HandleTerrainClick) Question

[Shadowhunter12]

Good Morning Everyone.

I am looking to work in AOE spell targetting into my bot and I have a question.

I am using the following code and offset:

public static uint HandleTerrainClick = 0x3FCD50;

        [UnmanagedFunctionPointer(CallingConvention.Cdecl)]
        private delegate bool HandleTerrainClickDelegate(CTerrainClickEvent clickEvent);
        private static HandleTerrainClickDelegate WoWFunction_HandleTerrainClick;
        
        [StructLayout(LayoutKind.Sequential)]
        private struct CTerrainClickEvent
        {
            public ulong GUID;
            public Location Position;
            public uint Button;
        }

        public static bool ClickRemoteLocation(Location location)
        {
            if (WoWFunction_HandleTerrainClick == null)
                WoWFunction_HandleTerrainClick = WoW.Memory.CreateFunction<HandleTerrainClickDelegate>(new IntPtr(PatternOffsets.HandleTerrainClick), true);

            return WoWFunction_HandleTerrainClick(new CTerrainClickEvent { Position = location, GUID = 0, Button = 0 });
        }

I am getting an AccessViolationException when running that function, so I am assuming that my offset may be incorrect or that I am not calling it correctly. Does anyone have any experience with the HandleTerrainClick function that may be able to point me in the right direction?

Thanks in advance!

Post crash dump (careful to remove your account, character name, guid etc.).

Thanks for your quick response. I'll work on getting the crash dump.

Just looking at the code, is the offset, CTerrainClickEvent, and the method of calling look correct?

Thanks again!

Isn't argument of that function supposed to be a pointer (ref in C#) to struct?

Seems like a common reason for an access violation to me.
