hi all again

as the title says. . .

whats mean (. . .)?

like in this

function table.find(t, ...) 

thanks before hand

In your case, the "..." works as a table of arguments later used in table.find function.

Example of using "..." as argument:

addCommandHandler("text", 
function( player, command, ... ) 
    local text = table.concat({...}, " ") -- This way the player can type texts with [b][u]spaces[/u][/b]. 
    outputChatBox(tostring(text)) 
end)

Each function that has "..." as parameter, passes another hidden table that is arg. So, you can use arg instead of creating new table with all parameters. In addition, arg table has a

addCommandHandler("text", 
function( player, command, ... ) 
    local text = table.concat(arg, " ") -- This way the player can type texts with spaces. 
    outputChatBox( text ); 
end) 

table.concat returns string so there is no need to convert it to string.

is there any need for the semicolon here: outputChatBox( text );

just curious because ive never needed to use one like this.

In most scripting/programming language, semicolons are used, but in lua its optional (makes no difference if used or not).

ah so 50p used it out of habit.. ok thanks....

i see it quite a lot within code from experienced scripters but have never needed to use it myself...

i wasnt sure if it had some use in Lua or not.

thanks for the quick reply.
