CLEO Help Hooking RPC

[PlasticBottle]

Hello, so i've been trying to do some things with RPCs, but I can't understand shit

I get that there is incoming and outcoming RPCs, that we can intercept and all, but I don't know how to use it in SB. I read the sf_raknet tutorial on blasthack, but it's hard to understand.

Can someone just explain to me (like really fast) how to do it ? I'm stuck with this code:

[shcode=cpp]
{$CLEO}
{$INCLUDE SF}

0000: NOP



0001: wait 1 ms

0BE3: raknet setup_incoming_rpc_hook @RPC_IN



:RPC_IN

0BE5: raknet 0@ = get_hook_param 0@ //THIS IS WHERE I'M STUCK
//I WANT TO GET INCOMING GAMETEXTS, SO I CAN COMPARE IT LATER (I KNOW HOW TO)







then

0AB1: @FAKE_KEYPRESS 1 _OFFSET_KEY_ 0x1c // Press the JUMP key









:FAKE_KEYPRESS //SNIPPET

1@ = 0xB73458 

005A: 1@ += 0@  // (int)

0A8C: write_memory 1@ size 1 value 255 virtual_protect 0

0AB2: ret 0

[/shcode]

Read the SF file if you include it. All the constants are there.
The hook param is one of the following, PACKETID being the PACKET or RPC id.

// RakNet Hook Parameters
const
PARAM_BITSTREAM = 0
PARAM_PACKETID = 1
PARAM_PRIORITY = 2
PARAM_RELIABILITY = 3
PARAM_ORDERINGCHANNEL = 4
PARAM_SHIFTTIMESTAMP = 5
end

[shcode=cpp]
0BE5: raknet 0@ = get_hook_param PARAM_PACKETID
if 0@ == RPC_SCRDISPLAYGAMETEXT 
then
   0BE5: raknet 1@ = get_hook_param PARAM_BITSTREAM
   do_stuff_with_the_incoming_data_at 1@
end
0BE0: raknet hook_ret TRUE/FALSE
[/shcode]

Thank you very much!
