Learning Lua... (Just a random post from a lua super noob.)

[syn.]

Code: [Select]

x = "Kenny"
if x == "Brandon" then
print("Hi, " .. x)
end
if x ~= "Brandon" then
print ("You are not Brandon, " .. x)
end


Code: [Select]

You are not Brandon, KennyI swear I started crying when this actually worked!
God I feel like I accomplished something this week:)

[Decicus]

While I understand you're a "Lua super noob", this would work as well, in the same way.

Code: [Select]

x = "Kenny"
if x == "Brandon" then
print("Hi, " .. x)
else
print ("You are not Brandon, " .. x)
end
It does the same exact thing as your code, but basically it does "Is 'X' Brandon? No. I'll print the 'else' code".

Other than that, you're doing good. I remember doing something that was similar in my earlier Lua days.

I used to do things like this in BASIC back in.... 1998. You're doing it right. Learn the basics. Learn how coding works. You'll pick up more advanced stuff in time.

Too many people just try to jump right in and start editing. Then they don't know what they're doing, only how to modify certain things.

[Megiddo]

I echo Decicus and MrP. We see so many people come through these forums asking us to teach them to do xyz task, by which they normally mean "do it for me". Good to see you're not getting frustrated by what may seem like small accomplishments.

Learning one language will make learning other languages easier.

Lua is a good place to start.

Agreed.
I started Lua when I was 12...
...then took up Java at 13, and blew threw it.
The only thing that irks me about C-based languages is that they're so complicated... *cough* PHP */cough*

Code: PHP

1. echo("PHP Y U SO HARD? D:");
2. die(":'(");
3.  

The semicolons at the end of functions... just... why?

Syn, said in another topic you wanted challenge.
Here you go.
Small one. Table included.
See if you can tell what it does/outputs before posting it into a lua interpreter (gmod included)

Code: [Select]

c = 0
x = { 0, 100, 20, 99 }
for n = x[1], x[3] do
   print ( n )
   c = n
end
print ("I just counted to ".. c )


[syn.]

can i look at the reference manual? 

[Neku]

Here's some more tables.

Can you figure out how this handles medals?

Code: [Select]

MEDAL[1] = { "Pasta Lover", "Obtain some yummy pasta.", 5 }
MEDAL[2] = { "Panty Thief", "Steal some underwear.", 10 }
MEDAL[3] = { "Pig Molester", "Bother a harmless pig.", 5 }
MEDAL[4] = { "Crisis", "Drop into crisis mode for the first time.", 5 }
MEDAL[5] = { "Error", "...", 20 }


local function Medalsvn
          print( "Medal: " .. MEDAL[3][1] )
          print( "Hint: " .. MEDAL[3][2] )
          print( MEDAL[3][3] )
          player.medalvalue = player.medalvalue + MEDAL[3][3]
end

eyes hurt. hate tables. pig molester?

[Neku]

Want me to explain what's going on in mine?

[syn.]

yes please neku:) I really don't like tables now

[syn.]

20! Jam it's 20! you freaking added 100 and 99 into the table for no reason... starts at 0 because c = 0 and then goes up by one all the way to 20 because you put x[3] and 20 is your 3rd variable (or whatever it's called) and n = c and blahblahblah. I want more jam pls:D

edit* : just checked on SciTE and I'm pretty sure I'm right.

[Neku]

Think of tables as variables inside of a variable.

I went a tad further and made tables within the table.

To call a table's value, you would do

Code: [Select]

table[x]

Say I wanted to call the point value of Pig Molester.
I would do

Code: [Select]

MEDAL[3][3] -- Another [] because it's inside another table.

I think I might have one for you...
Simple, but weird if you don't know it all...

Code: [Select]

tab = {
"Billy",
"Bob",
"Joe"
}

math.randomseed( tonumber( tostring( os.time()):reverse():sub( 1, 6 ) ) )

print( "Winner: " .. tab[ math.random( 3 ) ] )Yep, more tables. C:
I could've just posted my raffle name picker code, but its function namings and heavy commenting are too easily understandable... :p
EDIT: *crosses fingers and hopes I didn't screw anything up while typing on a lag guy as heck iPod tough 4G with autocorrect on*
EDIT 2: Fixed a few blatant syntax errors (probably added a few too) and added spacing.
EDIT 3: Fixed a blatant syntax error that I should've noticed but didn't due to my 20/100 uncorrected vision and my usage of a mobile device to make this post (I have switched to a computer since then ).
EDIT 4: Tabs!
