Str, dex and int should always be between 10 and 45, inclusive. Skill1, skill2, and skill3 should never be the same value. Skill1, skill2, and skill3 should always be between 0 and 45, inclusive. Skill1value, skill2value, and skill3value should always sum to 100. Skill1value, skill2value, and skill3value should always be between 0 and 50, inclusive.

Packet ID: 0x01 Packet Name: Disconnect Notification Packet Size: 5 bytes Sent By: Client Submitted: MuadDib Description No longer Active. Packet Breakdown BYTE[1] cmd BYTE[4] pattern (0xFFFFFFFF)
Packet ID: 0x02 Packet Name: Move Request Packet Size: 7 bytes Sent By: Client Submitted: MuadDib Packet Breakdown BYTE[1] cmd BYTE[1] direction BYTE[1] sequence number BYTE[4] fastwalk prevention key Notes Sequence number starts at 0, after a reset. However, if 255 is reached, the next seq # is 1, not 0. Fastwalk prevention notes: each 0x02 pops the top element from fastwalk key stack. (0xbf sub1 init. fastwalk stack, 0xbf sub2 pushes an element to stack) If stack is empty key value is 0. (-> never set keys to 0 in 0xbf sub 1/2) Because client sometimes sends bursts of 0x02’s DON’T check for a certain top stack value. The only safe way to detect fastwalk: push a key after EACH x021, 0x22, (=send 0xbf sub 2) check in 0x02 for stack emptyness. If empty -> fastwalk alert. Note that actual key values are irrelevant. (just don’t use 0) Of course without perfect 0x02/0x21/0x22 synch (serverside) it’s useless to use fastwalk detection. Last but not least: fastwalk detection adds 9 bytes per step and player !

Uox based emus convert post 2.0.7 data of this packet to pre 2.0.7 data if Type >=0xc0. (different view of it) If Mode&0xc0 then there are keywords (from speech.mul) present. Keywords: The first 12 bits = the number of keywords present. The keywords are included right after this, each one is 12 bits also. The keywords are padded to the closest byte. For example, if there are 2 keywords, it will take up 5 bytes. 12bits for the number, and 12 bits for each keyword. 12+12+12=36. Which will be padded 4 bits to 40 bits or 5 bytes.
