Title: Scripting challenges!
Post by: . on June 10th, 2015, 11:13 AM

I decided to be a troll and have some fun with scripters by testing their creativity. So, I will post some challenges and let's see if you can do complete them and how creative is your approach. I will choose the most creative one's based on how elegant the implementation is. Sux we do't have a spoiler tag on the forum :D

RULES

>~~STAFF MEMBERS EXCLUDED! WE ALL KNOW YOU CAN READ A DOCUMENTATION UNLIKE THE USUAL SCRIPTER~~ EVERYONE IS IS FREE TO JOIN!
>~~DON'T POST THE CODE HERE. POST IT ON PASTEBIN(http://pastebin.com/) OR SOMETHING SIMILAR AND POST THE LINK HERE.~~ POST THE CODE HERE AND USE THE SPOILER TAG
>YOU ARE NOT ALLOWED TO LOOK AT SOMEONE ELSE'S CODE. IF YOU DO THAT THEN YOU'RE DISQUALIFIED AND YOU DON'T DESERVE TO CALL YOURSELF A SCRIPTER.
>BE HONEST WITH YOUR IMPLEMENTATION. IF YOU COPY SOMEONE ELSE'S IMPLEMENTATION THEN GO KILL YOUR SELF.
>IF YOUR IMPLEMENTATION HAPPENS TO MATCH SOMEONE ELSE'S CODE AND YOU DIDN'T LOOKED AT HIS CODE. THAT'S FINE.
>>HAVE PHUN AND TRY TO LEARN SOMETHING.
>>>MUST HANDLE CRITICISM!!!

The spoiler tag can be used with [-spoiler] ... [-/spoiler] (without the '-'). Example of adding code in spoiler tags:

[-spoiler]
[-code]
print("This code should be hidden!");
[-/code]
[-/spoiler]

The '-' is added to allow you to see the tags. Otherwise would be treated as a tag and would be converted to HTML. You don't need he '-'.

CHALLENGES

~~PRINT ALL THE VALUES OF AN ARRAY WITHOUT USING ANY LOOP CONTROL STATEMENTS.~~ (Winner: @Stormeus )
IMPLEMENT A TIC-TAC-TOE(https://en.wikipedia.org/wiki/Tic-tac-toe) GAME USING SPRITES THAT CAN BE PLAYED BETWEEN TWO PLAYERS AND SUPPORTS BETTING (Winner: ONGOING... )

ATTENTION: A single post per application is allowed to avoid spam. If you feel like you want to update your code then edit the post and add a [-hr] (without the '-') tag at the bottom and with a bold text saying UPDATE: following the update...

ATTENTION: If your post ends up rather too large. Consider using an external source for the code. The external source must be trustworthy (like pastebin.com) and the source host must be permanent.

LET THE GAMES BEGIN!

Damn.

You are free to participate but would be unfair to the other scripters ;D I tried that spoiler tag a while a go and didn't work. Perhaps it was added in later updates.

This is a pretty horrible way but

(click to show/hide)

Code: [Select]
local array = ["This", "And", "That", "Why", "Not"]; if (array.len() <= 1) print(array[0]); if (array.len() <= 2) print(array[1]); if (array.len() <= 3) print(array[2]); if (array.len() <= 4) print(array[3]); if (array.len() <= 5) print(array[4]); //And so on...

Come on people. Is this the best you ca do. I already got two approaches while I was eating ;D

Hints (don't read!)

(click to show/hide)

Hint about the first approach: Recursive...
Hint about the second approach: Delegates...

** Kratos_ was returning to home . ( Just a 5 min drive to home )
** Kratos_ checked mobile . ( Thinks, hmm ok. Something to post )
** Kratos_ reached home & opened lappy . Writes some bunches of code .
** Kratos_ opened forum & boom all fun destroyed . ( S.L.C disclosed )

Btw here it is ,

(click to show/hide)

Code: [Select]
function onScriptLoad() { _test_(); } // function for defining & printing array entities function _test_(ctr=0) { // sample array holding the entities local array = [ "mercury", "venus", "earth", "mars", "jupiter", "saturn", "uranus", "neptune" ]; // printing the array slot indexed at 'ctr' print(array[ctr]); // updating the counter by 1 ++ctr; // checking if the updated counter goes beyond the range of array slots ( 0 - n-1 ) if( ctr >= array.len() ) return 0; // calling the function with updated counter [ Tail Recursion ] _test_(ctr); }

I haven't fully disclosed :D Was just a single word hint. And besides, you did the code before you saw the hint :P Waiting for more approaches. I'll do a review tonight when the first challenge ends. So far you have the approach that works. The only thing that's bugging me the fact that you declare that array on each recursion.

If you want to have fun keep looking for the other approaches ;D

function PrintArray(array, num=0)
{
print(array[num]);
num+=1;
if(array.len() != num) PrintArray(array, num);
}

Kudos to @vcmptr for having a clean approach. Here's another stupid way to get it all in one string with the format function. This isn't recommended and there's better ways :D

(click to show/hide)

Code: [Select]
local arr = [2, 354, "foo", 43, 5.234, 675, "bar", true, {a = 23, b = 34.546}]; // Nethod 3 -------------------------------------------------------- function VarargsApproach(arr) { // Insert the format string in the argument pack arr.insert(0, ""); // Generate the format string local fmt = function(arr, idx = 0) { if (idx < arr.len()) { switch (typeof arr[idx]) { case "integer": arr[0] += "%d\n"; break; case "float": arr[0] += "%f\n"; break; case "string": arr[0] += "%s\n"; break; default: arr[0] += "%s\n"; try { arr[idx] = arr[idx].tostring(); } catch (e) { arr[idx] = "(null : 0x00000000)"; } break; } // Go down the rabbit hole callee().call(this, arr, ++idx); } } // Skip the format string fmt(arr, 1); // Insert the 'this' environment arr.insert(0, this); // Print the f*er ::print(::format.acall(arr)); } // We make a shallow copy of the array // Otherwise we edit the original VarargsApproach(clone arr);

I'm just curious to see what other methods I can get.

Well you said that we cannot use loops but said absolutely nothing about using timers, so here it is!

(click to show/hide)

Code: [Select]
function onScriptLoad() { local array = ["once", "upon", "a", "time", "Cinderella", "was", "going", "somewhere"]; loopn <- 0; NewTimer("PrintAllOfThese", 1, array.len(), array); } function PrintAllOfThese(array) { print(array[loopn]); loopn++; }

I only said loops are forbidden. Any other trick is yours to use :D BTW, I think your code needs the new timers to work. Which are not yet compiled.

We have recursive, we have timers, we have format. I'm still waiting for someone to find the last approach :D

The first challenge ends in about 2 hours. Impress me :P

Got a newer one it's much more efficient (hint it uses the function arraytostring anti-hint I made that function myself)

(click to show/hide)

Code: [Select]
local ra = ["Cinderella", "ate", "nuttella", "then", "blah"]; print(arraytostring(ra, ", "));
And that function
Code: [Select]
function arraytostring(xarray, xsplitter, xstarting=0, xcurrent="") { if (xstarting >= xarray.len()) return xcurrent; else return (arraytostring(xarray, xsplitter, xstarting+1, xcurrent + ((xstarting == 0) ? "" : xsplitter) + xarray[xstarting])); }

One-line delegate abuse (two lines if counting the array).

(click to show/hide)

Code: [Select]
local arrayTest = ["test1","test2","test3","test4"]; // .apply replaces each value in an array with the returned value. // // This is a cheaty way of printing stuff without loops and we need to // return the original value to avoid filling the array with nulls. arrayTest.apply(function(v) { print(v); return v; });

One-line delegate abuse featuring lambdas:

(click to show/hide)

Code: [Select]
// Squirrel internally clones the array and uses the return value from map to // fill the cloned array. // // If you were to look at the returned array from .map, you'd see a bunch // of nulls, as we never return anything. arrayTest.map(@(v) print(v));

Finally someone found the last approach. See people! That's what happens when you RTFM. I thought I was going to close this without anyone comming with the proper solution ;D

Either way. Here's all of them:

(click to show/hide)

Code: [Select]
local arr = [2, 354, "foo", 43, 5.234, 675, "bar", true, {a = 23, b = 34.546}]; // Nethod 1 -------------------------------------------------------- // Recursive functions function RecursiveApproach(arr, idx = 0) { if (idx < arr.len()) { ::print(arr[idx]); // Go down the rabbit hole RecursiveApproach(arr, ++idx); } } // Initial call RecursiveApproach(arr, 0); print("---- ---- ---- ---- ---- ----"); // Nethod 2 -------------------------------------------------------- // Default delegates + lambda function DelegatesApproach1(arr) { // NOTE: arr becomes filled with nulls now arr.apply(@(v) ::print(v)); } // We make a shallow copy of the array // Otherwise we fill the original with nulls DelegatesApproach1(clone arr); print("---- ---- ---- ---- ---- ----"); // Default dlegates + function function DelegatesApproach2(arr) { // NOTE: arr doesn't become filled with nulls now arr.apply(function(v) { ::print(v); return v; }); } DelegatesApproach2(arr); print("---- ---- ---- ---- ---- ----"); // Nethod 3 -------------------------------------------------------- function VarargsApproach(arr) { // Insert the format string in the argument pack arr.insert(0, ""); // Generate the format string local fmt = function(arr, idx = 0) { if (idx < arr.len()) { switch (typeof arr[idx]) { case "integer": arr[0] += "%d\n"; break; case "float": arr[0] += "%f\n"; break; case "string": arr[0] += "%s\n"; break; default: arr[0] += "%s\n"; try { arr[idx] = arr[idx].tostring(); } catch (e) { arr[idx] = "(null : 0x00000000)"; } break; } // Go down the rabbit hole callee().call(this, arr, ++idx); } } // Skip the format string fmt(arr, 1); // Insert the 'this' environment arr.insert(0, this); // Print the f*er ::print(::format.acall(arr)); } // We make a shallow copy of the array // Otherwise we edit the original VarargsApproach(clone arr);

I will do a review of each after I finish my movie :D

Ok, review time :D

The first one comes from @NE.CrystalBlue and I must say it's very disappointing. Not only that you do a sh!t load of if statements but you also have to add more code every time the array gets bigger. Not a viable solution.

Second one comes from @Doom_Killer.

Third one comes from @Kratos_ . And shows the use of recursive functions. One more thing I need to suggest to almost everyone is to stop using stuff on onScriptLoad() event because Squirrel is executed the same way PHP is. Top down. Like the following example:
