wth, if this seriously works, that's awesome

    public function TimerAttach takes timer t, real time, real value, code func returns nothing
        call TimerStart(t, value, false, null)
        call PauseTimer(t)
        call TimerStart(t, time, false, func)
    endfunction

However, this is slower than LoadInteger from my tests when I was working on TimerTools
R2I(TimerGetRemaining(t) + 0.5)

 

[Troll-Brain]

Since we have legal ways to do the same that's not awesome at all.
If the bug is fixed, your map is broken (yes still very unlikely)

 

[HappyTauren]

Woah, that timer exploit is awesome.

 

[Troll-Brain]

It would be if we didn't have valid ways, it's not the case, so it's just one more annoying bug.
Anyway i've updated the script.

 

[Ceday]

Image's brother.

function GetNextLightning takes nothing returns lightning
    local lightning l = AddLightningEx("CLPB", true, 0, 0, 0, 0, 0, 0)
    call DestroyLightning(l)
    return l
endfunction

 

[Troll-Brain]

It should be the same for texttag, because IIRC there is also no handle reference counter, but as far i know texttags from the game (like the one displayed when gold/wood is collected, or when an unit is hurted by a critical attack, ...) don't share the same stack.
So that would be 100 % useless.
Should be also the same for lightnings.

This is nothing new already found 2006 by Captain Griffen. http://www.wc3c.net/showpost.php?p=832021&postcount=3

 

[Troll-Brain]

Yeah i've said it was him, not when though or gave the link.
Anyway by creating this thread, i just wanted to highlight silly jass bugs, not getting some people enjoy ...
They are bugs for god sake ...

The only one that i've listed from now which could be used, is for lightning but it's more likely that you will mess up with the internal image stack, maybe if you don't destroy them and only change their color (not tested).

 

[baassee]

JASS, why so random

Brilliant stuff.

 

[Magtheridon96]

Direct0rz cUT111111!!!!

This could be useful as a nice little repository for people to read

 

[Ceday]

I have tested before, you can change colors of abilities with lightning effect.But destroying them will crash iirc.

Ok, then i will add it on the next update.

 

[Zwiebelchen]

I love the IsBlizzardLazy function... should be a native...

 

[Adiktuz]

I think the most useful one here is the IsBlizzardLazy function... that alone should get a DC...

 

[Magtheridon96]

Can you credit Daeod (or however it's spelled ) for the GetFutureNextImage function?
I think he's the one that first documented something about it back in 2009

 

[Troll-Brain]

I think i've discovered it by myself, but nevermind ok, i will do it in the next update.

 

[Magtheridon96]

Yes, actually you did, but it was just done before as well

 

[Nestharus]

He doesn't need to credit anyone if he discovered it himself. It doesn't matter if it was done before.


Don't credit peeps for your own work.

 

[Troll-Brain]

But i'm not 100 % sure, maybe i've read it a long time ago (2009 ?) and just remembered randomdly what Deaod said, you know how the brain stores and retrieves information is not always obvious.
So in doubt i will credit him, that isn't like it's an "hard work" anyway.

 

[Blarto]

The wheel was invented before too, you should credit the inventor every time you make something round and spinning.


Btw, I'm still struggling to understand what IsBlizzardLazy does ...

 globals
        public player Local_player = GetLocalPlayer() // comment this line if you want to use your map, else it will crash on loading
    endglobals

I think global rect = GetWorldBounds() also crashes...

Yep, but hopefully no wheel is involved here.

Btw, I'm still struggling to understand what IsBlizzardLazy does ...

It doesn't work maybe ?
I've used a valid ability rawcode, so it shoudln't return null, anyway check the comment for this function in the most up-to-date common.j lying in your mpq, it will be clear why i've choiced this name.

I think global rect = GetWorldBounds() also crashes...

Probably, i also know that some other functions don't work without any crash, i'm currently too lazy to test all of them, and i usually only write statements that i'm 100 % sure, let's say personnaly tested, or eventually by really reliable people (and i know only one guy).
But don't take me wrong i also sometimes make wrong statements, i just hope i'm much more reliable than the average of people.

 

[Blarto]

Hehe, I get it now... And here I was, thinking about what it supposed to do.

[Troll-Brain]

Wow, i want one !

Wait ..., i've already many Apple products.

Spoiler

(that's only a joke i've none of them, they are not funny unlike this machine on the video)

 

[Magtheridon96]

Changed the thread name because it's not a library, but a repository showing some cool things you can do with JASS, and approved.

 

[AnonymousPro]

still usable?

• test
  • Events
    • Time - Elapsed game time is 0.00 seconds
  • Conditions
  • Actions
    • Hashtable - Create a hashtable
    • Unit - Create 1 Footman for Player 1 (Red) at (Center of (Playable map area)) facing Default building facing degrees
    • Hashtable - Save Handle Of(Last created unit) as 0 of 0 in (Last created hashtable).
    • Game - Display to Player 1 (Red) at position 0.00,0.00 the text: (Name of (Load 0 of 0 in (Last created hashtable).))
    • Hashtable - Save Handle OfNo unit as 0 of 0 in (Last created hashtable).
    • Game - Display to Player 1 (Red) at position 0.00,0.00 the text: (Name of (Load 0 of 0 in (Last created hashtable).))

This, at least in 1.36, will display 2 times "Footman".
I got the following solution :

// Cannot null an existing value in a hashtable by doing SaveHandle(h,k,v,null)
// So we save a dummy handle to destroy it, so the value becomes null
// I picked location because it is the lightest possible handle I found
function HashtableResetHandleValue takes hashtable h, integer k, integer v returns nothing
    call SaveLocationHandle(h,k,v,Location(0,0))
    call RemoveLocation(LoadLocationHandle(h,k,v))
endfunction

Even if Blizzard fixes this my function won't break the game.
Of course it is not as fast as the intended behavior, since it makes 1 function call, 2 hashtable calls, one handle creation and one handle destruction just for 1 hashtable call.
Do not hesitate to test it with other kind of handles and explore further because I may have spoke too fast.

EDIT duh I never thought RemoveSavedHandle existed. My bad.

 

[Bribe]

What is wrong with RemoveSavedHandle?

 

[FlameofChange]

What is wrong with RemoveSavedHandle?

I just discovered this function like 15s ago.
Welp, looks like I reinveted the wheel.
I stand corrected.

How does the unit shadow code work and is it still working? I haven't been able to modify them at all however I am sure I had it working once years ago, tried on latest reforged as well legacy 1.28.5.

Probably was fixed at the same time the return bug was fixed if it hasn't worked in so long.

 

[FlameofChange]

My little contribution. Dunno if it already existed before but in 1.36 it happens.
Select a map with this library, then create the game and Warcraft III crashes.

library crashYourGameAtLobbyCreation
    globals
        multiboard mapBomber=CreateMultiboard()
    endglobals
endlibrary

That's been a thing for forever. The "main" thread crashes if you try to create a unit directly in the globals block.

But... this is a multiboard, not a unit.
Are you talking about any handle ?
But Hashtables don't make the game crash at lobby ?
How and why it crashes at lobby creation ?
I'm curious right here.

Good questions! The same issues occur in Lua as well. Some types of WarCraft 3 handles, like units, cannot be created before the "main" function is called. So I think this has to do with how the engine instantiates itself during the game's startup sequence. The "config" function is tailored to setting stuff that is relevant only to stuff that may need to exist during the game lobby menu, whereas the "main" function is designed to hit as soon as the actual loading screen starts. How it all works under the hood is a bit weird. There is no "0 second async timer" in the loading screen; the timer will always wait until the user has pressed a button to start the game.

Oh I see. I understand now. Looks like I invented warm water again
