Param tutorial

Hi my dear friends,

Could someone give me a short tutorial of parameters or give me a link to help me understand?

Thanks.

function something(a, b, c)
print(a, b, c)
end

something(1, 2, 3) -- prints 1 2 3
something(1) -- prints 1 nil nil

Keep reading ahead of this point and you learn more about functions, but for only arguments you can stop there.

Its the same thing, those "parameters" in onSay and every other interface/function/metamethod/etc work the same way.

In TFS 1.2 you have the "separator" in the talkaction but it will only separate the first occurance so if you have separator=" " and use:
/command buy 1 2 3

You will have as "param": "buy 1 2 3" then you have to use the function "string.split" provided in the library to separate those " ". You can see how to do this in lots of default talkactions tfs for example:
