Code: Select all
struct Player_Update{
/*0000*/ int32 activity;
/*0004*/ float unknown2; // 1
/*0008*/ float direction1;
/*0012*/ float unknown3[8];
/*0044*/ float speed;
/*0048*/ float side_speed;
/*0052*/ float unknown4;
/*0056*/ float orig_x;
/*0060*/ float orig_y;
/*0064*/ float orig_z;
/*0068*/ float orig_x2;
/*0072*/ float orig_y2;
/*0076*/ float orig_z2;
/*0080*/ float unknown5[3];
/*0092*/ int32 unknown6;
/*0096*/ float unknown7[3];
/*0108*/ int32 unknown8;
/*0112*/ int32 grid_location;
/*0116*/ float x;
/*0120*/ float y;
/*0124*/ float z;
/*0128*/ float direction2;
/*0132*/ float unknown9;
/*0136*/ float unknown10;
/*0140*/ float speed_x;
/*0144*/ float speed_y;
/*0148*/ float speed_z;
};
That is our limited understanding of the structure. Note that I'm sure it has changed since that was valid, but the information we need from the packet has stayed the same.

thanks LE, that does help. been trying all week to determine the player packets now.
But i`m seeing something that doesn`t make any sense.
The World server is seeing the following packet
Movement PAcket
0: 2E 83 90 40 3F B7 86 0D - 02 D0 84 EE EC 3C 1E FE | ...@?........<..
16: FF A1 3F 80 F8 BB 64 0C - BF F0 39 ED 8E 81 40 | ..?...d...9...@
but the client is sending the following.
192.168.10.104 -> 192.168.10.4
0000: 00 09 00 1d 25 3c 00 00 00 00 45 dc dd 52 1f 00 ....%<....E..R..
0010: 00 00 2e 83 40 90 3f b7 84 d0 02 0d 86 ee ff fe ....@.?.........
0020: 1e 3c ec a1 80 3f f8 bf 0c 64 bb f0 8e ed 39 81 .<...?...d....9.
0030 40 @
the information is there, but it`s not scrabbled ?
I`m sure you wisdom in packets can easily clear this up.

Could you paste the whole packet for the first packet? I need to know where you got that and what it is.

the first packet is from the "Player::PrepareIncomingMovementPacket" of player.cpp, i`m using the DumpPacket(data, len).
it`s just strange, all the right values are there in the second packet, but not in the correct order.

Oh, That. Yah the data has to be reversed before it is useful. It is called from Unpack. I think they added it to screw with anyone trying to develop something that reverse engineered their packets.
