[fixed] - Packet ID: 0x34 - Issue

Post by MontuZ » Tue Apr 15, 2008 6:42 pm

Packet ID: 0x34 (Get Player Status)
BYTE[1] getType
� 0x04 - Basic Stats (Packet 0x11 Return)


There's no distance, concealed and possibly hidden(unchecked) checks for Basic Stats request.

People are using this with injection to detect when staff are online.

It's a really simple packethook fix I may upload if enough people request.

I didn't test this myself yet, but if what you said is valid, do you know if this is an old issue or introducted in the new releases (say, 096/097)? Not that it's too important, I'm just curious.

Concerning the fix, I'm looking forward to it's release. Since you are working on the distro (aren't you?), wouldn't the script suit well in it until the (presumed) core fix is introducted?

Well I remember before that people used to just Single Click staff and since there was no distance or visibility checks on them then, the name would appear in the lower left but I guess after that was fixed in 096, they're turning to alternatives.

I use two hooks against it, 0x34 and 0x6c packets.

Very cool, maybe you could release the other packet?

Code: Select all

use uo;

program sendtarget()
  Print( "Hooking incoming 6C packet..." );
  return 1;
endprogram

exported function Handle6CReceive( chr, byref packet )

var staffs := {0x1, 0x2, 0x3};  // staff chars serials here
var serstat := packet.GetInt32(7);
var staff;
if(chr.cmdlevel)
	return 0;
endif

if(serstat in staffs)
	staff := SystemFindObjectBySerial(serstat);
	if(staff && !staff.concealed)
		return 0;
	endif
	packet.SetInt32(7, chr.serial);
endif

  return 0;
endfunction
