Sometimes bytes are not bytes, i really don't understand how you manage to write any code if you're not able to see such things... faith in programmers lost...
Code:
//Warp
[C -> S][7010]
10 00 <-- Your "BYTE"
BC 63 RegionID
01 00 4C 43 00 00 00 00 FF FF 57 43 PositionOffsets
01 00 Angle?
//Makeitem
[C -> S][7010]
07 00 <-- Your "BYTE"
6B 00 00 00 RefItemID
00 OptValue
//Loadmonster
[C -> S][7010]
06 00 <-- Your "BYTE"
51 3A 00 00 RefMobID
01 Amount
00 MobType?
