There is no code to handle 'use item' without item position on 7.72 servers. Client must have open backpack with given item to send position of item to server (position like: 5th slot of 2nd open backpack).
So you got to add handling of 7.80+ packets for 'item use' in server and edit few lines in client.
OTCv8 requires changes in that file:
Clean, ready to use version of OTClientV8 - Alternative, highly optimized Tibia client - OTCv8/otclientv8
github.com
There are 5 IFs:
Code:
if g_game.getClientVersion() < 780 then
that change functionality for 7.72 protocol (search item in backpack). Change them to
if g_game.getClientVersion() < 0 then
, so hotkeys on client side will work same for every version of tibia protocol.
About server side: you need some C++ programmer to check what is required to make you server handle new packets. Maybe OTX2 downgrade was made 'fast' and author did not remove code that handle 7.80+ packets.
