Oh wow I cannot believe there has been no comments to this news article. Then again, it isn't really relevant to many people. I wonder if there is any other way to back up these PMs but also shutting down the forum site.

Is EndIf or End not required in TI-BASIC (83/84)?
I know that End is required in Casio Basic and EndIf in TI-nspire Basic
End (for function in Lua) too.

Oh! I thought it was customary to give peanuts only in the Introduce Yourself! Board and direct new members to start a topic there
And good stuff CoD_Black_Ops_Master. Here in Omnimaga we aim to help and contribute.

Well hi everyone, I have been slowly trying to learn TI-nspire Lua here.
I have thought for a bit, made some demo beginner programs with the help of jimbauwens , and learnt a lot along the way (also creating a batch file for Luna for quick lua -> tns conversion). But I still have a long way to go.

So I had the tns file for 15puzzle but it didn't work, probably because it was designed to work with OS<3.0.2.

Fortunately I have managed to extract Problem1.xml from the tns file (rename it as a zip), copy to Notepad++ save as a .lua file, then used this page, to fix some errors/discrepancies with xml coding and tinspire Lua code, and got it working!
Played it, got it solved in 353 moves.

Now here I post the source code and tns file of 15Puzzle, edited by Jonius7 for OS 3.0.2 and above

And I think one of the best ways to learn is to analyse source code line by line and try to understand what it means.
So I shall try here with some help to dissect this source code:

function on.charIn(ch)
if ch == "r" then
board = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 }

-- Randomize
local swaps = 0
for i = 1, 16 do
local j = math.random(i, 16)
if i ~= j then
board[i], board[j] = board[j], board[i]
swaps = swaps + 1
end
if board[i] == 16 then
empty = i
end
end

-- If the number of swaps plus the number of empty-space movements is odd,
-- then the puzzle is impossible, so do an impossible move to make it possible
-- (exchange the space with a tile two squares away)
if (swaps + (empty - 1) + math.floor((empty - 1) / 4)) % 2 == 1 then
local i = (empty + 7) % 16 + 1
board[empty] = board[i]
empty = i
board[empty] = 16
end

moves = 0
platform.window:invalidate()
end
end

on.charIn("r")

function on.paint(gc)
local won = true
for i, n in ipairs(board) do
if n ~= 16 then
local x = (platform.window:width() - 128) / 2 + 32*((i - 1) % 4)
local y = (platform.window:height() - 128) / 2 + 32*math.floor((i - 1) / 4)
gc:drawRect(x, y, 30, 30)
gc:drawString(n, x + (30 - gc:getStringWidth(n)) / 2, y + 15, "middle")
end
won = (won and n == i)
end

local str = moves .. " moves"
gc:drawString(str, (platform.window:width() - gc:getStringWidth(str)) / 2, 0, "top")
if won then
str = "You win! Press R to reset"
gc:drawString(str, (platform.window:width() - gc:getStringWidth(str)) / 2, platform.window:height(), "bottom")
end
end

function on.arrowKey(key)
local dir
if key == "left" and empty % 4 ~= 0 then
dir = 1
elseif key == "right" and empty % 4 ~= 1 then
dir = -1
elseif key == "up" and empty <= 12 then
dir = 4
elseif key == "down" and empty > 4 then
dir = -4
else
return
end
board[empty] = board[empty + dir]
empty = empty + dir
board[empty] = 16
moves = moves + 1
platform.window:invalidate()
end


Oh really? I'm not sure if that happens for me. It looks fine for me. Could you post a screenshot please?

It does look very nice overall! Shall benefit the community greatly, and bring some relief to the feeling of being stuck on 3.0.2.

Hi heepoopsalot,
Please do not necropost in old topics, unless for a particular reason that is relevant to the current events of today.

Wow, this has been left from August last year!
I wasn't sure if there were any actual developments on the Facebook Page anyway.

Yeah hopefully https might work soon.

Also nice, because now people can get Omnimaga news directly from Facebook so this might bring them back when they don't visit for a long while.

Maybe, if they remember about the Omnimaga Facebook Page, as it might not be a bookmarked page on the left sidebar.
