Better way to hide ANY button founded by leandrotp. But it crash on MAC versions.





Command Buttons Stacking

You do not have enough space on the unit's command card because standard buttons occupy it?
Now you can fix it! Fold unnecessary buttons under top-left corner button and free some space for abilities.
Bonus: hidden buttons are not activated when you press their shortcuts on the keyboard. You can assign a skill shortcut to the vacant key.
Note: these changes will apply to all units and all players, use wisely!

How to use?


1. Make a copy of Units\CommandFunc.txt file from war3.mpq
2. Open it with Notepad
3. Change lines "Buttonpos=X,Y" to "Buttonpos=-2147483648,-2147483648" for all command buttons you want to stack.
4. Save file
5. Import file in your map
6. Change imported file full path to "Units\CommandFunc.txt" (Right click -> Modify File Properties... -> check Use custom path -> type new path in enabled textbox -> OK)
7. Save map and test how it works!

Which command button will be shown on the top?


It seems that game places first loaded command button on the top. There are two stacking types:
- Type A - Attack, Attack Ground, Stop
- Type B - Move, Stop, Patrol, Hold Position
- Theoretically, Type C - Hero abilities

If first loaded unit:
- can move and can attack, game will place Movement buttons (Type B) first.
- can move and can not attack, game will place Movement buttons (Type B) first.
- can not move and can attack, game will place Attack buttons (Type A) first.
- can not move and can not attack (or command card hidden with Ward classification), game will ignore this unit.

In what order the game loads the units? I can not say exactly how this works, but: buildings loaded before units, and probably heroes loaded after buildings and before units.

Warning! Stacking order is always set to Type A after loading saved game. Keep it in mind if your map uses standart Save/Load.

How to define stacking type?


1. Open Object Editor in World Editor (F6)
2. Open Units tab
3. Select: Standart Units -> Human -> Melee -> Buildings -> Guard Tower (hgtw)*
3.5 Copy it if you want use standart Guard Tower in map later.
4. Modify Standart Guard Tower:
- for Type A stacking you must keep tower attack ability. (when you select tower, you must see Attack button)
- for Type B stacking you must set Movement - Speed Base to 1 (or higher value). (when you select tower, you must see Move button)
4.5 You can change different values to make tower more "dummy", but keep in mind:
- Stats - Is a Building must be TRUE
- If you changing attack, watch attack availability in command card.
- Guard Tower must be visible for all players. However, you can replace model with dummy and make it unselectable with Locust.
5. Place edited Guard Tower on the map.
6. Change ownership of placed Guard Tower to Neutral Passive. (so it will not interfere normal gameplay)
7. Save map and test it!
*If you find an object that overrides Guard Tower, please write it in comments.

Important info

  • Stacking order depends on placed on the map units at the game start.
  • Stacking order does not change during the game.
  • Buttons stacking works properly only in 0,0 slot of command card (top-left). Attempts to stack two command buttons in other slots led to crashes.
  • Minimal value for start stacking buttons is "Buttonpos=-2147483648,-2147483648" (closer to 0 values lead to crashes in some situations, still not sure what effect have closer to -inf values).
  • Hidden in the stack buttons can not be activated via shortcuts. Only displayed buttons work.
  • This method changes command card for all units and all players.
  • It seems that this method does not cause game crashes. Nevertheless, I advise to use it with caution as all "hacks".

If you are using Command Buttons Stacking in your map, please share link to it here. It will be interesting to see how it works in real project. :)

As much as I like this discovery: you should have asked a mod to move your thread in the lab section instead of creating a new one.
I created a new thread for 2 reasons:
1. Thread in [thread=261559]The Lab[/thread] shows the research process, when this thread in Tutorials has final information and step by step instructions.
2. I afraid that moving thread will change thread URL and all direct links on attachments will "fall off".

Well, I still couldn't find a way to make my method work in macs, I didn't give up yet, but while I don't get it, your method is the preferred one, so I'd like to add some things about it.

  • Whenever a button is going to be displayed, the game calls a function to determine its location. This function takes the desired X and Y position, and attempts to find an available slot for that button.
  • The function takes the Y value, multiplies it by 16, and adds it to a memory address. Then it reads the DWORD at the resulting address and adds it to the value of X multiplied by 4.
  • The result of this operation will be the address of a structure that represents one of the 12 slots. I will call this structure UI_SLOT
  • The UI_SLOT structure has a "occupied" property located at offset 0x94. If UI_SLOT.occupied is false, that slot will be used for the button.
  • However, if UI_SLOT.occupied is true, the function will begin a loop to find the nearest available slot
  • The loop starts at the originally desired position, and goes until the (3,2) position. If it finds an available slot there, it will be used.
  • If the function does not find an available slot with this, then it will begin a new loop, but in reverse. This loop starts at the original position and goes backwards, until the (0.0) position.
  • If the function does not find an avaliable slot after these two loops, that button will not be displayed.
Now, see what happens when you set any of them to the extreme negatives:

  • The value -2147483648 (in hex 0x80000000) will be mutiplied by 16, and with this, the most significant bit will be lost, and the result is 0.
  • The X value will be multiplied by 4, and the result will also be 0.
  • So the result of this operation will be the address of the UI_SLOT structure of the (0,0) slot.
  • When the first button is placed, that slot is available and it will be used. For the next button, it will not be available anymore and the function goes to the loop.
  • The first loop ends when Y>3, but this an unsigned comparison. Therefore, the value 0x80000000 will always be greater than 3, and this loop will end before the first step.
  • Then it goes to the reverse loop, which ends when Y<0. As -2147483648 is always lower than 0, this loop won't get a chance to run as well.
As you can see, the result is that all buttons, with the exception of the first, will not be displayed. This is 100% guaranteed to work, in any ocasion.
As a consequence of this, it's possible to stack all buttons in ANY position, not just (0,0). But this is how you should do it:

Buttonpos=X,Y
-2147483648   1      2      3   X / Y
-268435456*
-268435455
-268435454
Unfortunately your method requires at least 1 button to be displayed, and can't hide the cancel button. I'm still trying to make my method work on mac, but maybe it's not possible at all because of different memory layout, I can't be sure for now.

Update: You can also use the value -268435456 for the Y position only instead of the maximum negative. This value will be accepted by the World Editor, so you can use it to hide normal abilities too.

Bonus

You can make ANY ability appear on top of all stacked buttons!!!

I just found what would be the "Type C" stacking that you mentioned: If you add ANY ability to the 1st unit of the map (in your test map, that would be the Guard Tower), and remove the movement and attack of that unit, then that ability will appear on top of the stacked buttons!

And you can do that to any number of abilities: just add those abilities to the Guard Tower, and disable its movement and attack. I didn't test this behaviour when loading saved games though.

The "Hero Awaken" ability ('Aawa') takes precedence over ALL buttons, and will override them if they are stacked in a slot. So if you need a command card with 12 spells, you can use 'Aawa' as a base for one of them.

It's a bit weird to get it working, you need to give a dummy dead hero to all players, and the tooltip of the ability will be the 'revive' tooltip of that hero. This ability can provide up to 4 buttons, and these buttons have maximum priority in the command card. If you want a passive button, you can also use Orb of Slow with 'Aawa' as effect ability.

When I get home I'll make a testmap for demonstration.
Yeah but why would you do that if you can just use the remaining button in 0,0 as your dummy anyway?
If for example "move" is the remaining visible button at 0,0, just redirect all "move" orders to the spell you want to cast.

Maybe you would want an instant or passive spell instead of a targeted one... I just wanted to show that the possibility is there, if anyone ever needs it.

Updated my post with new findings...
I experiment a little bit with nearest values and found an interesting thigs:
1. World Editor working oddly with big values, it will round them with 16 (and after that with 32) steps. So you can not use -268435455 and -268435454 for Y, it will be rounded down to -268435456.
2. And accidentally I found that Y -268435440 represent hero buttons. So you can place shortcuts here. And they will stack too! 12 slots is real!
146877d1437671874-how-stack-standart-buttons-remove-patrol-hold-position-etc-shortcuts_to_portraits.jpg
Button positions from top (F1) to bottom (seventh) icons
Code:
Buttonpos=24,-268435440
Buttonpos=20,-268435440
Buttonpos=16,-268435440
Buttonpos=12,-268435440
Buttonpos=8,-268435440
Buttonpos=4,-268435440
Buttonpos=0,-268435440
I notice that hero buttons handled by the game in different way than command card, here is main difference:
- Buttons will appear on the screen when friendly unit with corresponding abilities selected.
- Green highlight around standart buttons doesn't updated and always freezed in first unit selected state (i.e. if unit stays - Stop button will be green always)
- Shortcuts for sidebar buttons doesn't work, you can only click on them.
- First placed button will hold place and doesn't overrided by other buttons.
- If you deselect a unit, buttons will stay on the screen. You can click on that buttons for other unit and if it can handle fired order id, it will use corresponding skill.
- Button will update if selected unit change corresponding ability (noticed this with hero abilities learning)
- Hero portraits will stay on top of stacked with this approach buttons.
- Sidebar buttons can not show cooldowns, but possibly can show numbers (like hero ability points).
- Layout refreshed when hero dies, revives, hired, gains/spends ability points.

So you can grab all buttons and place them under F1 hero, add a dummy hero (i.e. Game Rules, Inventory, etc.) and everything will work.

Also you do not have to bother with stacking order, because all buttons will be hidden under hero portrait.

This approach needs to be tested, but so far everything looks stable.

Fun never ends with this game. Can you use normal hotkeys (m for move, a for attack) for the abilities on the left bar? If you have one, can you share your testmap?

Nope, only clicks.

Here is updated demo with new approach, all buttons (except Hero ability) are hidden under first hero portrait: View attachment CommandButtonsStackingDemo2.w3x

Now we need testers with MAC-s, I hope this method will not crash :)

Just tested, it also works for units.
So if you set the Peasant Art - Button Position Y to -268435440, you can click that portrait to train a peasant when selecting a town hall.

It also works for buildings, so you can build buildings with this. Just use a peasant, use his build once and the buildings will stick to the sidebar and can be built. Hotkeys doesn't seem to work for them tho.

And.. Since the buildings are not in the build menu anymore, I guess you can fit in more buildings to be built from a worker.
The game crashes if two different units/abilities has the same button position.

But yeah, I guess it can be useful for some abilities, like Call of Arms.

EDIT: The buttons are removed when you train/revive a hero, and will be added back again when selecting that unit that has the abilities.
Same thing when a hero learns an ability.
So I guess you could modify which icons to show by triggers.

(Sorry if this was already known, just testing on my own).

Interestingly, I can not make game crash with two different units on same button position. Do you use Mac PC?

EDIT: The buttons are removed when you train/revive a hero, and will be added back again when selecting that unit that has the abilities.
Buttons also refreshed when hero gains/spends an ability point (even if currently dead). So far everything looks good: just add 1 dummy, or track current hero and use trigger that do +1 -1 ability point to any player's hero every N milliseconds.

Here is updated example with 12+5 buildings for peasant: View attachment CommandButtonsStackingDemo2edit.w3x

It would be awesome if someone find way to remove black bars under buttons, i hope this texture doesn't used everywhere and can be easily replaced with 1x1 px transparent dummy.
 
Could you provide a test map with the method that you know crashes on a mac? I have a mac, but I am running it through Wineskin since wc3 has so many issues on the latest OS (so technically it is the Windows client). If it crashes, then I wouldn't mind testing whichever test maps you send my way.

EDIT: The map in post #14 loads and runs fine. The map in #17 goes into some sort of infinite loop and crashes.

Then I guess we have method that can hide any standart button under hero portrait.

And possibly way to have 12+6 buttons, but it needs debugging. leandrotp is a true genius at that part. Maybe he could find safe values that can be used both on PC and MAC.

EDIT: Can you check these maps? I reduce number of used slots in each map, so theoretically we can find maximum available sidebar buttons for Mac:
7. View attachment CommandButtonsStackingDemo2_7.w3x
6. View attachment CommandButtonsStackingDemo2_6.w3x
5. View attachment CommandButtonsStackingDemo2_5.w3x
4. View attachment CommandButtonsStackingDemo2_4.w3x
3. View attachment CommandButtonsStackingDemo2_3.w3x
2. View attachment CommandButtonsStackingDemo2_2.w3x
1. View attachment CommandButtonsStackingDemo2_1.w3x
To activate sidebar slots just need to open peasant's build menu.

holy amazeballs!

I think this is easily the biggest WC3 exploit I've seen in a while. It's a shame that hotkeys don't work on these sidebar buttons. That could have been THE way to create an MMO-like ability HUD.

It's still awesome though. I really have to check out if I can get a possible use out of this (probably not, as I use the quickbar for displaying allied heroes) ... there must be a way to use this for something really cool.

It drops to about 1 fps for all of them as soon as the map starts, so I had to exit.
So it doesn't crash? I guess this happens because I use "Time - Periodic Event" with 0.00 value (tested it on PC - 10000 sidebar refresh actions per second) maybe on MAC it executed even more times.
Here is another test map: View attachment Test_1.w3x - sidebar refresh starts after 5 seconds of gametime and executed every 0.03 s (33 times per second).

It's still awesome though. I really have to check out if I can get a possible use out of this (probably not, as I use the quickbar for displaying allied heroes) ... there must be a way to use this for something really cool.
For example you can make "Battle Mode" button. So default sidebar buttons will be:
1. Hero
2. Backpack
3. Material Bag
4. Talents Archive? (you can split them into 2 spellbooks: base and advanced - 24 talents total (or even add nested spellbooks pagination, then there is no limits!). And also add Learn talent button here, that will open hidden hero skills menu. And because you make talents choice one from three, you can place talent learn buttons to sidebar aswell)
5. Usefull Things (revive mercenary, roll, etc)
6. Game Options
7. Battle Mode
When you click on Battle Mode, all spellbook abilities (Talents Archive, Usefull Things, Game Options) and Material Bag (probably with Backpack for total 6 hero slots?) removed (just remove corresponding spellbook abilities and refresh sidebar with +/-1 skill point) and your Party interface activates. Battle Mode replaced with Peaceful Mode to make vice versa actions. This could even trigger automatically when entering/leaving battle, but I think it's better to add as option, not default behaviour.
Sidebar spellbooks can contain sidebar buttons with "Cancel" at the bottom (so only 1 cancel + 3 buttons very comfortable for clicking + 12 normal buttons in command card).
Also all buttons (+learned talents) can be repeated in backpack for user's convenience. (will require additional dummy abilities with normal positions and shortcuts ofc)

So far I see three main problems:
- Mac compatibility testing.
- These black bars under sidebar buttons.
- Sidebar clumsiness with low refresh rate.
+ It needs at least 1 hero for each player to hide stacked standart buttons and refresh sidebar.

Yeah I actually had a similar idea... the problem is that it would be unintuitve to have the controls placed there. For someone who digs self-explanatory systems like me, this is not easy to get by.

I guess things that looks like buttons and appear on the screen when you select hero (and disappear when you select other unit) are pretty noticeable and self-explanatory. Just tell the player that he can click on them (introduction quest for example or big splashscreen with arrows pointing on buttons/backpack/etc and text descriptions, displayed when hero picked).

Perhaps splitted buttons (i.e. spellbook with 3 buttons on sidebar and 4 on command card) may be confusing, because player will notice changes only in sidebar zone and command card will be in blind-spot.

And tooltips appearing near to command card when you hover over sidebar buttons are little uncomfortable, but we can not change this - frameDef can not be modified at runtime.

Hmm... I evaluated some possible designs for that in my head and just couldn't find any layout that was somewhat satisfying.

But I could imagine this being amazing for 3rd person shooters or fullscreen systems. For example, you could use the skill point number of the icon to display ammo or just use those buttons like tabs that select specific sub-menus in FSI.


But keep experimenting guys! Maybe you can find something even cooler, like having abilities displayed on the right side of the screen aswell.

Also, have you found a method to replace the idle worker button with this? This could be really interesting, as you can't have a hero button there by normal means, so you could use it to trigger an interface element or have a spellbook or menu placed there.
You can already do this with the idle worker button, but it introduces a nasty delay due to the selection event. Having an actual ability there would remove this lag.

Wait... so I can have 12(command card)+7(heroes)+6(inventory) buttons per unit? Omfg

EDIT: The F1-7 hotkeys don't work either for those abilities. Need to find a way.
EDIT2: Found a way to make the hero buttons show cooldowns and the bluish thing for when they can't be cast due to mana. Just level up the hero.
EDIT3: Found a way to make hero buttons castable by hotkey. If you have an ability with the same order ID in the command card, it will use its hotkey for both. While one is uncastable the other will use its hotkey instead.

I guess this happens because F1-F4 buttons read pointer to unit (hero) from specified location. So when we place skills here, it just points to nothing.

Black background for bars displayed here with same reason - game can not retrieve unit, so check "is hero dead" returns 0, and hp/mp values are 0 - so we can see a blank bars.
EDIT2: Found a way to make the hero buttons show cooldowns and the bluish thing for when they can't be cast due to mana. Just level up the hero.
You can also just give and take away 1 skill point to player's hero, this will refresh everything in HeroBar.

Sounds good.

After searching for barewords in game.dll, I can guess that Blizz use these names for UI elements:
HeroBar - 7 buttons at top left
PeonBar - 1 button at bottom left
CommandBar - 12 buttons bottom right
Inventory - 6 buttons near to CommandBar
Too bad what everything is compiled here, so I can not find used texture or understand logic (maybe it just hardcoded fill with #000 for these backgrounds).

P.S. I found that black background under HeroBar buttons disappers when hero dies, but idk how it can be simulated without a hero and for all buttons, not only for one.

2. And accidentally I found that Y -268435440 represent hero buttons.

Forget about that man, I had also found it in my testings, but didn't post it because it will surely crash on mac. The reason it works in windows is because the game uses Storm.dll to allocate memory, and Storm allocates similar objects near each other (based on class name).

But the mac version uses the operating system's malloc to allocate everything, so the objects are placed in unpredictable places in the memory. I didn't really test it in mac because I didn't suceed in installing Mac OS, but I'm pretty sure it will crash unless you are extremely lucky. (But anyway, it would be technically unsafe, the only thing 100% safe is to stack buttons into one of the 12 slots)
 
@Alex: Tested it. It worked fine with 33 fps.

As for the issue around Macs:
  • Battle.net doesn't work for Mavericks (10.9) and above.
  • You can't even install the native wc3 binaries unless you're running 10.6 or below with PPC architecture (or Rosetta if you're on 10.6 with intel).
  • w3arena's mac client runs on WINE internally.

For those reasons, most Mac users have had to switch to a wineskin configuration or they run wc3 through bootcamp -> Windows partition. The number of mac wc3 players are already small, and I doubt that anyone using a mac would want to sit on a 10.6 upgrade forever unless it is a really old computer. I don't think it is necessary to cater to those few people. Most ppl I've encountered on reddit or w/e asking about macs ended up using Wineskin. As long as they have a suitable alternative, it should be fine.

Macs are basicly not supported by WC3 anyway. Sad but true. Having optimized textures with less mipmaps for example will crash macs aswell. All the good stuff doesn't work on macs either, like enabling local files.

Local files work through Wineskin, thankfully. :D The low mipmap blp thing is still an issue though, even on Wineskin.

So, I have bad and good news.
Bad => HeroBar is compiled into game.dll and can not be modified with Jass functions.
Good => We have a workaround for this!

Just look at this: View attachment Test_2.w3x :)

And how it works:
- Game redraws HeroBar when any hero in game obtain skillpoint. You can add dummy hero for neutral passive and run refresh trigger for him.
- Black bars under buttons removed when player's hero dies, and they stay hidden even if you remove hero from the game. You can add 7 dummy heroes for each player, kill them and then just remove from the game.
- Also, because we use only PC safe code in map, we can use 0,-11 to hide unwanted command card buttons completely and make 7 buttons universal sidebar.

P.S. I think to make separate tutorial for this feature, with nice demo map. :)

UPD: Wow! Noticed that game crash after playsession with sidebar buttons. Right after closing scores screen.
UPD2: I guess game tries to wipe heroes data after playsession, but our HeroBar doesn't contain real heroes data and crash happens.

I was able to reproduce the crash in your test map and debugged it: it's caused by the Repair ability. I don't really know why, but it seems that this ability can't be placed on the sidebar. Try changing its position back to the command card and tell me if the crashes happen.

Looks like some buttons are safe for placing in sidebar, but certain buttons cause crash. For example in demo map if last opened sidebar was peasant's skills - game will crash, but if you open peasant's Build menu - game will end normally. Demo map updated, now there are only safe skills

UPD: Looks like problem happens with activating abilities and buying items.
Standart command button - ok
Build - ok
Train - ok
Upgrade - ok
Item in Shop - crash after score screen
Learn Hero Ability - ok
Normal Hero Ability - crash after score screen
Autocast Hero Ability - crash after score screen
Passive Hero Ability - ok
Normal Unit Ability - crash after score screen
Autocast Unit Ability - crash after score screen
Passive Unit Ability - ok
Active Item Ability - crash after score screen
Passive Item Ability - ok
Doesn't work on position of abilities placed inside spellbooks! - so idea with nested sidebar spellbooks isn't possible.

So far I see one dirty solution for this: player types "quit", game disables selection, forces player to select dummy unit with 7 safe sidebar buttons, shows defeat for him and after that enables selection.

UPD2: Hmm, Reincarnation ability cause crashes after score screen too. I guess all things with cooldowns add unsafe pointers that game tries to clear after score screen. Will try to figure how to avoid this.
UPD3: Seems like all cooldown logic is compiled in game.dll and can not be modified. I guess game saves pointer to a timer for each cooldown, that cleared when score screen displayed, and when game tries to clear all data connected with hero bar it also uses pointer to a wrong location in memory and crash happens. Pretty interesting that game work with placed not hero buttons here anyway.
UPD4: Just noticed that spellbook shows only 11 abilities, even if you totally hide Cancel button. I guess this is hardcoded limitation.


So sidebar can be used to:
- Show useful command buttons that doesn't require often use via shortcuts (i.e. Attack for friendly fire, or Patrol/Hold Position)
- Add up to 7 buildings in Build menu
- Add up to 7 trainable units in buildings
- Add up to 7 upgrades in buildings
- Move hero skill learning to sidebar
- Display important passives (i.e. game rules, or maybe different passives that indicates something and changed with triggers)
- Add up to 7 safe active abilities without cooldowns for any unit:
>> Reveal (Andt) as dummy for ground-target skills.
>> Defend, Magic Defense as dummy for toggleable skills (also it fire order id even if unit is stunned).
>> Shadow Meld as dummy for non-target skills.
>> Root as dummy for unit <-> structure skills.
+ You can make sidebar buttons with any shape using alpha channel, because HeroBar doesn't render any backgrounds behind buttons. ( it's possible to make interesting hero portraits with this knowledge, just don't forget about non-removable black bar behind HP/MP, hero button shiny square glow and skill points counter in bottom right corner )

And if you think that game crash after play session is ok, or you can handle it with tricky triggers:
- Add up to 7 abilities with cooldowns for any unit

And I recommend not to move/hide cancel button, it doesn't give much bonuses (only +1 slot in build menu), but really annoying when you can not close opened spellbook with ESC button.

UPD5: Demo map now use only safe skills - View attachment Sidebar.w3x
P.S. Sidebar works a bit weird with standart save game option: game will save, but if there are ability buttons - game will crash on load. Interesting that game will load if there are only building buttons, but after that everything turns unstable and game can crash in next playsession. So sidebar is suitable for multiplayer or arcade maps only.

Guys, thanks a lot for these amazing findings and elaboration :)

Just a note: building the buildings from the sidebar does not work for me (newest wc3 patch, win7 64bit, started from JNGP newest version)

The latest patch removed this exploit. Does anyone have a solution? :(

Yeah, use a spellbook or dummy unit with 0 movement speed as interface with rally as ability for copying point-orders. Both require a little bit of triggering though spellbook does actually cost quite a bit of object editor work if your using over 100 abilities.

Might be other possibilities however I don't have enough knowledge about them yet to explain.

I've found a solution in Demo Map - Full Command Cart | The Helper
It does a brilliant thing where it takes away a player's alliance control over their own units and uses a spell with a "smart" base order id in place of actual smart orders, which allows them to act normally with triggers. Plus you won't even have a single standard button remaining! However, it's a little difficult to work with since units will issue double smart orders and fire off events twice, and they won't have voice responses, but it's perfectly fine otherwise with a few workarounds. Not sure how well it works with ordering several units at once.

That system makes it completely impossible for the player to select multiple units at once. So it's useless except for maps where the player doesn't need to control more than one unit.

Wait for the next patch, they've said they're going to whitelist this.

Can someone (@Kam?) please tell Blizzard that whitelist is not the solution? I've read the topic at battle.net, where he says they're gonna whitelist some values. First, the (0, -11) combination IS NOT SAFE, and should not be whitelisted. Second, there are many combinations of values that allow for button manipulation, like -2147483648, -268435456 or -268435440, and by now many maps are using different numbers, so it would be difficult for them to whitelist every possible combination.

In my opinion, the best solutiion would be not to touch it at all, and revert it to what it was before 1.27b, I mean, no safety checks (just let the community care about that). But if they are really paranoid with this thing, they should implement a check that uses a bitmask, to allow only the highest negative values, instead of manually whitelisting each number.

Btw, I really think they should keep this thing like it was before the patch. I've been thinking of a way to combine this trick with memory reading, to implement the Hero Bar buttons in a way that would be 100% safe. I'm pretty sure it would be the best for everyone it there was no safety check on button positions.

I have passed it on. We have discussed this before so I know it's being worked on in some capacity.
 
@leandrotp

A response from Blizzard per your request:

"
I am whitelisting the value, but the internal logic is different
If it sees the value it doesn't attempt to register the button at all
So from the outside it looks like the trick still will work; but in reality it is not actually do the same thing that it was doing in 1.27a

I didn't want to introduce a new api and I didn't want to break maps that used it.

"
 
nice attitude we have there. goddamit, this company used to be best of the best :C

The primary concern in all of this is to leave previous maps in tact. I am not familiar with the intimate details, but the decision was made to ensure continuing functionality. I can assure you this team is very dedicated and there is a good reason for the decisions they make.
