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

[syn.]

I know it probably goes from 20 to 100 or 100 to 20 but I don't know what b does :p

[JamminR]

Which, and how?

[MrPresident]

The third variable (b in this case) is a step.
See if that helps you.

[syn.]

you made a table with x which had 4 keys/values inside then with

Code: [Select]

for n = x[3], x[2], b do you chose the 3rd and 2nd Key/value which I'm assuming means they go from one to the other. but i dont know what "b" does in the previously shown code. lol nvm Pres just replied and since it's a step it would mean that it goes either

20             100
30              90
40              80
50              70
60      or     60
70               50
80               40
90               30
100             20

[MrPresident]

Code: Lua

1. a = 0
2. b = 10
3. c = 20
4. x = { 0, 100, 20, 99 }
5. for n = x[3], x[2], b do
6.    print ( n )
7.    if n == 50 then c = 60 end
8. end
9.  

Ignore, for a second, what is actually in that for loop.

The structure for a loop like that is

for n = a, b, c do

a is the starting value
b is the ending value
c is the step.

Now, let's go back into Jam's code.
There are 4 values in table x, but this code only uses 2 of them. The 3rd and the 2nd value inside of the table.

Now, try again. You are close, but you can't give two answers and just say "one of these is correct"

[syn.]

oh okay thanks pres I didn't know the order of the values and stuff. It's
20
30
40
50
60
70
80
90
100

Got it syn.
I'll delve more into tables and table specific for loop functions in my next puzzle.
Not right now though. (it's now ~115am my time, and I'm running on fumes)

In your learning, are you finding any challenges/questions you're having trouble with specifically?
Perhaps I, or MrPresident if he so feels, could make a puzzle or two specifically aimed at challenges you're specifically having.

Also, i just realized, this post may better fit in developers corner (it's both off-topic to ULX, and, it is learning development/code logic.)

[syn.]

not having many problems anymore thanks to Mr.Pres I think I'm ready for a tiny bit more

[MrPresident]

Pick a topic.

[JamminR]

Let's go table ipairs.
Just wait till I get to next statements inside the for loop.
Easy at first.

Code: [Select]

x = { 0, 100, 20, 99 }
for k, v in ipairs( x ) do
   print ( k, v )
   if k == 3 then print ( "I found " .. v .. "!") end
end

I am very glad there are people on here who aren't the usual "do this for me" type.

Good job on your efforts syn.

Agreed on both statements.

Thanks guys:) I'm glad that theres people willing to help out a complete stranger on problem that has nothing to do with them, *clap clap* for ulysses team and everyone else who helps out!

By the way, I'd like to hop on your server to check out how it's going.
Send me the ip sometime.
