Problems with extendedOpCodes

[lucas123]

Hello OTLand.
I'm with some problems with extendedOpCodes.

I'm using TFS 1.1

I'm with two problems:
first:
sometimes this happens:

ERROR: ProtocolGame parse message exception (0 bytes unread, last opcode is 50, prev opcode is -1): InputMessage eof reached
ERROR: ProtocolGame parse message exception (0 bytes unread, last opcode is 50, prev opcode is -1): InputMessage eof reached

but, sometimes it works fine (without change anything).

Why this happens?


second problem:
When I want to send a table from server to client, I've got an error, so I transformed all the table into a string and this works fine for send, but, how to get the string back into a table? (I tried using loadstring but it isn't working ='( )

talkaction:

function table.val_to_str ( v )
  if "string" == type( v ) then
    v = string.gsub( v, "\n", "\\n" )
    if string.match( string.gsub(v,"[^'\"]",""), '^"+$' ) then
      return "'" .. v .. "'"
    end
    return '"' .. string.gsub(v,'"', '\\"' ) .. '"'
  else
    return "table" == type( v ) and table.tostring( v ) or
      tostring( v )
  end
end

function table.key_to_str ( k )
  if "string" == type( k ) and string.match( k, "^[_%a][_%a%d]*$" ) then
    return k
  else
    return "[" .. table.val_to_str( k ) .. "]"
  end
end

function table.tostring( tbl )
  local result, done = {}, {}
  for k, v in ipairs( tbl ) do
    table.insert( result, table.val_to_str( v ) )
    done[ k ] = true
  end
  for k, v in pairs( tbl ) do
    if not done[ k ] then
      table.insert( result,
        table.key_to_str( k ) .. "=" .. table.val_to_str( v ) )
    end
  end
  return "{" .. table.concat( result, "," ) .. "}"
end






local spells = {}
function getSpells(player)
    local selfVocation = player:getVocation():getName()
    local dir = "data/spells/spells.xml"
    local spell = io.open(dir, "r")
        for i in spell:read("*a"):gmatch('<instant(.-)</instant>') do
            local spellVoc = i:find('vocation name="'..selfVocation..'"')
            if (spellVoc) then
                local spellName = i:match('name="(.-)"')
                local spellNeedlearn = "0"
                spellNeedlearn = i:match('needlearn="(.-)"')
                    if player:hasLearnedSpell(spellName) or tonumber(spellNeedlearn) == 0 then
                        local spellLevel = i:match('lvl="(.-)"')
                        local spellWords = i:match('words="(.-)"')
                        local spellMana = i:match('mana="(.-)"')
                        local spellGroup = i:match('group="(.-)"')
                        local spellExhaustion = i:match('exhaustion="(.-)"')
                        local spellGroupcooldown = i:match('groupcooldown="(.-)"')
                       
                        if player:getLevel() >= tonumber(spellLevel) then
                            local temp = {name=spellName,words=spellWords,level=spellLevel,group=spellGroup, groupcooldown=spellGroupcooldown, exhaustion=spellExhaustion, mana=spellMana}
                            table.insert(spells,temp)
                        end
                    end
            end
        end
end

function onSay(player, words, param)
    getSpells(player)
    for i = 1,#spells do
      --print(spells[i].words)
    end
    local text = table.tostring(spells)
    --print("\n\n\n\n"..text)
    Player.sendExtendedOpcode(player, 53, text)
end

Client-side:

function init()
  ProtocolGame.registerExtendedOpcode(GameServerOpcodes.GameSpellBarOpcode, opCodes)  -- opcode 53
end

function terminate()
  ProtocolGame.unregisterExtendedOpcode(GameServerOpcodes.GameSpellBarOpcode) -- 53
end
local spells = {}

function opCodes(self, opcode, buffer)
  spells = {}
  print("Buffer: \n\n"..buffer.."\n\n")
  loadstring("spells = " ..buffer)()
  --table.sort(spells, function(a, b) return (a.level < b.level) end)
  print("tamanho:" .. #spells)
end

Thanks for help.

Solved.
change
loadstring("spells = " ..buffer)()
to

spells = loadstring("return " ..buffer)()
IDK why but the first problem has been solved too.
