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ID: 0x01 Packet Name: Disconnect Notification Packet Size: 5 bytes Sent By: Client Submitted: MuadDib Description No longer Active.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 !

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.
