ClickToMove questions?

[Viano]

Hi there,

Apoc posted the signature of click to move in one of his posts.

BOOL __thiscall CGPlayer_C__ClickToMove(WoWActivePlayer *this, CLICKTOMOVETYPE clickType, WGUID *interactGuid, WOWPOS *clickPos, float precision)

In C# I would replace WoWActivePlayer with IntPtr, CLICKTOMOVETYPE with uint, WGUID with ulong but what the heck is WOWPOS? A struct like the following?

public struct WOWPOS 
        {
            public float x {get; set;}
            public float y { get; set; }
            public float z { get; set; }
        }

So the C# definition should look like this. Right?

[UnmanagedFunctionPointer(CallingConvention.ThisCall)]
        private delegate byte ClickToMoveDelegate(IntPtr pointer, int clickType, ref ulong guid, ref Pos clickPos, float precision);

So why can't I call it like this without WoW crashing?

WOWPOS p = new WOWPOS();
            p.x = position.X;
            p.y = position.Y;
            p.z = position.Z;

            ulong guid = 0;

            ClickToMove(ObjectManager.Instance.Player.Pointer, 0x4, ref guid, ref p, 0);

If I am just moving my player do I have to use his GUID or just set it to 0 like above?

Just forget my post, I used wrong offset.

When marshaling structs, it's generally good practice to not use properties for the marshaled fields, and give an explicit struct layout.

Granted; these aren't really 'requirements', but it's better to be in the habit of doing these things, since the Marshaler has some pretty undocumented behaviors when you don't tell it exactly what you want it to do.

[StructLayout(LayoutKind.Sequential)]
struct WoWPos
{
public float X;
public float Y;
public float Z;
}
