You need to check to see if the file actually exists before buffering the file into Lua.
local filename = "sys/lua/saves/%s.txt"
local file = io.open(filename:format(player(id,"usgn"), "r")
local line
if not file then
line = {1, 0}
else
line = file:read("*a"):split()
end
level[id] = tonumber(line[1]) or 1 -- If line[1] is not a number, level[id] becomes 1
exp[id] = tonumber(line[2]) or 0 -- Same as above reasoning (prevents errors)
*nix servers handle line buffering differently. While windows denote newlines via /r/n, linux requires only /n. While it's not a big deal in this case, you do need to keep that in mind when dealing with io.lines.
Also, you declared savedie twice (I think that you meant to declare the first function as saveleave):
addhook("leave","save_leave") -- When you leave it saves
function save_die(id)
if (player(id,"usgn")>0) then
io.output(io.open("sys/lua/saves/"..player(id,"usgn")..".txt","w+"))
io.write(exp[id].." "..level[id])
io.close()
end
end
addhook("die","save_die") -- When you die it saves
function save_die(id)
if (player(id,"usgn")>0) then
io.output(io.open("sys/lua/saves/"..player(id,"usgn")..".txt","w+"))
io.write(exp[id].." "..level[id])
io.close()
end
end
