Looks like Hero and Players are both entities, and thus inherit methods from a base class. I guess the best way to determine base classes is to look through these guys and find similar functions

Calling a function with an incorrect number of arguments will display an Error with the number of arguments required for the function (it'll say it needs 1 more, but because of how Lua work, the instance of the object is the first param, so subtract 1 from the # of params that the function wants).

If you provide the wrong type of parameter for the function, it will tell you that you messed up and tell you what type it expects. This is incredibly useful for figuring out Parameter lists.

Useful scripts:

Add

Convars:RegisterCommand( "exec_lua", function execLua(...) ex = select(2, ...) loadstring(ex)() end, "execute lua stuff", 0 )

In your init function (Frostivus.lua:92) to create console command that executes arbitrary Lua code.

example: exec_lua "print('test')". Note the use of single-quotes in the lua code. Valve's console breaks " into separate params.

Print Table:

function printAllTables(t, prestring)
    out = ""
    for k,v in pairs(t) do
        print(prestring .. k .. " ["..type(v) .. ", "..tostring(v).."] ")
        if(type(v) == "table") then
            out = out..printAllTables(v, "\t")
        end
    end
    return out
end

function printTable(t) for k,v in pairs(t) do print('\t'..k .. ' ['..type(v) .. ', '..tostring(v)..'] ') end for k,v in ipairs(t) do print('\t'..k .. ' ['..type(v) .. ', '..tostring(v)..'] ') end end

I also manged to get a custom hud going that communicates with LUA: http://i.imgur.com/cCkYfev.jpg

Here's one I wrote that also formats it nicely:

function PrintTable(t, indent, done)
    if type(t) ~= "table" then return end

    done = done or {}
    done[t] = true
    indent = indent or 0

    local l = {}
    for k, v in pairs(t) do
        table.insert(l, k)
    end

    table.sort(l)
    for k, v in ipairs(l) do
        local value = t[v]

        if type(value) == "table" and not done[value] then
            done [value] = true
            print(string.rep ("\t", indent)..v..":")
            PrintTable (value, indent + 2, done)
        elseif type(value) == "userdata" and not done[value] then
            done [value] = true
            print(string.rep ("\t", indent)..v..":")
            PrintTable (getmetatable(value).__index or getmetatable(value), indent + 2, done)
        else
            print(string.rep ("\t", indent)..tostring(v)..": "..tostring(value))
        end
    end
end
