Write the GUID in the CTM InteractGUID offset
Write the X node coordinate in the CTM X position offset
Write the Y node coordinate in the CTM Y position offset
Write the Z node coordinate in the CTM Z position offset
Write the desired action type in the CTM Action Type offset
Code:
w.WriteUInt64(AdressCTM + (uint)CTM.InteractGuid, nodeGuid); //CTM.InteractGuid = 0x20
w.WriteFloat(AdressCTM + (uint)CTM.X, X); //CTM.X = 0x8C
w.WriteFloat(AdressCTM + (uint)CTM.Y, Y); //CTM.Y = 0x90
w.WriteFloat(AdressCTM + (uint)CTM.Z, Z); //CTM.Z = 0x94
w.WriteInt(AdressCTM + (uint)CTM.ActionType, 7) //CTM.ActionType = 0x1C
