$ulevel question

ryder911 · #1 03-24-2004, 11:00 AM

Can $ulevel be used with a number. Like $ulevel => 10? then player would have to be greater then 10 to do the quest?

And when using $ulevel in a quest sitution would it look like this?

if ($text=~ /Hail/i)($ulevel=>10){quest::say("Hello $name")

and another question, sorry for being a noob lol, but Wat is difference between { and ( im not sure when to use which. What does each do / stand for

Thanks any help or tips is appreciated

This is pure perl language. Answer to first is yes, and to second ... i wouldn't be able to explain

I found what () are for, but i cant find anything on {} seems like all the guides just skip explaining them lol, It doesn't say anything about it and all of a sudden on the guide it starts using them

Code:

if ($text=~ /Hail/i)($ulevel=>10){quest::say("Hello $name")

should be:

Code:

if ($text=~ /Hail/i && $ulevel >= 10){quest::say("Hello $name")

I believe ( is for an array, and { the start of the function. A wild guess, though :/

In general, braces {} are used to block code together, such as:

if(condition){code block to execute}

Parentheses are used for a couple of reasons: 1.) Group together mathematical expressions to control evaluation order (things are evaluated in the parentheses together before things outside, and 2.) Enclosing the arguments of a function.

Quick examples of each.

1.) Controlling the order in which expressions are evaluated.

1 + 5 / 7 = 12/7 = ~1.714
but
(1+5) / 7 = 6/7 = ~0.857

2.) Passing arguments to a function

quest::say("Hello $name");

quest::say() is a function that takes an argument, your string there, which is passed by enclosing it in parentheses.

Code:

if ($text=~ /Hail/i && $ulevel >= 10){quest::say("Hello $name")

should probably be:

Code:

if ($text=~ /Hail/i && $ulevel >= 10){quest::say("Hello $name");}

Should end lines with semicolons. Also good practice to keep watch of what braces {} and parentheses () you open to make sure you close them later.

Oooops, didn't see that. Just quoted and corrected the beginning. Nice spot :P
