@Abyssgard
MyFunreal just replied to me and said the following (maybe you can understand it better than me):
"i probably can't. I know of ways to do it, but the "probably best" approach is a vscript that adds the riotshield to the maps somehow.
the cheapest way however is just removing the melee weapon sctring in every missionfile. But that would unlock all melee weapons the game has in its melee weapon manifest. And that also won't work for custom maps that add their own melee weapons. Mutual exclusivity and such.
Perhaps some Vscript coder could do that. There's some on the "Dead 4 Mods" discord server. A link to that can be found on my profile. But i don't know enough about vscripting to even know if thats possible. :s"

Part 5/5
In short:
1- his mod currently works, although with some limitations.
2- Zaeryn's mod is not currently an option since it is outdated (Although I already (I've reported the problem, so I can just wait and hopefully he'll respond.)
3- Mr. Funreal could be a good option since he makes mods for the game and mods that fix issues, but it depends on whether he wants to or not.

Anyway, his effort and dedication in creating "Riotshield Unlocker w/ HUD Icon" is greatly appreciated, as it speaks volumes about his professionalism in creating mods. 😌

Part 4/5
And finally, regarding "Mr. Funreal", well... I don't know what the capacity is for him to create a mod so that the shield is available on all maps, both official and unofficial (Anyway, I left him a comment on his mod called "Proper Riotshield Texture" asking him about it if he could do it or not).
And it would be a matter of waiting for him to respond.

Part 3/5
At this point, I doubt he'll read my comment, but if he does, I'll tell him that he answered me.
I also don't know what your knowledge is, but if you manage to get the shield to also appear on unofficial maps, we would greatly appreciate it, since, as I told you, your mod is the ONLY one that currently works.
Since mods like this: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=3467385882&searchtext=riot make the shield functional and useful, not just another melee weapon, and of course, a mod is needed to make the shield appear. Luckily, his mod does make it appear on official maps, but it would be great if it also worked on unofficial maps.

Part 2/5
Regarding "Zaeryn" and his mod, well... unfortunately he disabled comments and didn't leave any links to any external accounts on his profile, but I managed to find his YouTube channel, which luckily shares the same name and profile picture as his Steam account. In his last video, which was 6 months ago, I left a comment informing him of the problem his mod was having and asking if he could update it (and hopefully he's okay and reads my comment).
Because the last update to his mod was on SEP 28, 2020 at 4:13 PM. (According to Steam) Even if we compare the date of the last update the game had (The Last Stand), it was September 24, 2020.

@Abyssgard
Part 1/5
I didn't think I'd get a direct response from the creator of this mod 😅

I really liked his mod. Although it's only limited to official maps, it's still a good mod, since his mod is the ONLY one that works perfectly right now (even after the game's latest update). 👏 And because his mod is the only mod that has the ability to display the shield via the console (although it's only limited to official maps), it's still a good mod. 👍

Regarding The Last Stand and Cold Stream, I have to say that I haven't played the Cold Stream map yet, so I can't tell you if the shield appears or not. But as soon as I get to play that map, I'll check all the locations and replay the map if necessary to see if it appears (I'm not promising anything, but I'll try 😅). And with The Last Stand, well... it's a shame the shield doesn't appear. 😞

Part 2/2:
~As for the updates, It's been years since I last touched modding or even played L4D2 so if i'm gonna update this I want it to be a one time big update since i need to do some research again to refresh my memory. =_=

~You could try reaching out to zaryn if he or any other modder likes to use my mod and integrate his unlocker on it, I would welcome it wholeheartedly.

P.S. if anyone wants to do the honors of "updating" I wouldn't really mind it and no need to ask perms for it, just knowing you people appreciate my mod is enough to me <3, just remember to credit Mr. Funreal since his creations were the basis and foundation for my creation.

@Колоссальный вет

Part 1/2:
Actually if I remember correctly adding new maps for this item to spawn in is as easy as adding 1 line (unique to each level either official or custom) to this mod's file. I only put the riot shield on some of the official maps I deem them fit. Also if I include them in all maps it would feel forced and too common which would ruin the immersion.
(I came to this decision as well because the same rule applies to other weapons as well like how you can see them on specific maps only)

~When I made this mod, Cold Stream was already an official map at that time but I can't really remember if I included it, and as for last stand... yeah i was planning on including that map as well but I could not find the time to do so. T_T

Part 2/2:
And unfortunately, no other mod has the particularity of showing the riot shield through the console, like this mod "Riotshield Unlocker". w/ HUD Icon"
Although I don't know if the creator of this mod @Abyssgard can take @Zaeryn's mod and somehow reactivate it, update it and at the same time combine it with this mod of his and make it compatible with his other alternative version "Riotshield (HUD icon only)"
But that already depends on the creator and if he has the knowledge to do it and if not, we just have to settle for this mod and that's it.

@Nephrite Harmony
Part 1/2:
In fact, this mod does work and delivers what it promised, but the only problem is that it is only limited to the official game campaigns and not custom maps (I even think this would work on The Last Stand and Cold Stream maps), since they went from being custom maps to official maps, therefore I think this mod would also work on those 2 maps.
Regarding Zaeryn's mod called "Riot Shield Unlocker" it is a mod that currently does not work and is outdated since I tried it and it does not work (I even tried it without any of my mods and only having that mod activated) and I could not see the riot shield normally or generate it from the console (Because it also did not let me do it from the console) it is most likely some kind of problem with the last update that the game had (And I mean The Last Stand)

@Media Buff this only works on official maps, I can't really get this to work on all custom maps since I would have to manually put the map in the codes, unless there is another way around it that's the only way i know of.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2969088742 i have to use zaryn's unlocker just to make it work because this one doesn't

nor does the hud icon show up

i have this installed but it won't let me grab one on tumtara

does this work on a local server?

it worked nice

you should add list of maps

What maps does it spawn on?

@Asaiah It only appears on certain maps, not all maps.

How to enable the mod? I cant spawn it with commands and it wont spawn on official maps

@DevelopMan The conflict is probably due the Unlocker that is included with this, as long as both mods work alongside each other just fine you can safely ignore the conflict, however you can also try the other mod provided in the comments that only changes the icon, but you would have to download a mod that unlocks riotshield in maps else it won't spawn in even with console commands.

Uh. Incompatible with this https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2096874283

@Unique horn Much appreciated.

@GI1TcH!mg G@M3R https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2243011542

can you link me the hud only then?

now I understand only certain maps allow to spawn riotshield

@★JคҜe★ If this mod is disabled yet you still can't pick up the riot shield then it's a bug for that custom map, you need to contact the creator of the map.

I can't use commands to spawn it either

no also

@★JคҜe★ Can you pick it up if this mod is disabled?

do you know why I cant pick up shield in Tumtara?

@GI1TcH!mg G@M3R My guess is probably because this mod has an unlocker with it that unlocks riot shields on certain maps, and with that it includes files that edit campaign maps so it somehow conflicts with anything that modifies the world data, if you want you can try and download the HUD only (link is somewhere in comments) and download an unlocker separately. But try checking first if both mods work together even if they conflict, if it does then it is safe to ignore.

hey i have some problems with this mod as i get conflicting issues with other addons which has nothing to do with the riot shield
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2241399325&searchtext=correct+boomer+legs

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2096874283
so wierd can you please fix them? i have no idea why these are conflicting it has nothing to do with the riot shield

^_^v

HUD Icon is so wonderful! But, Unlocker is not working... :(

Sorry I mistake, This mod so perfect! XD

@Masterman Here you go... lemme know if you still encounter problems after ;)

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2243011542

Oki oki i'll make one for HUD only, i'll link it here once it's done

as of right now, I am using another Didgeridoo unlocker that does more, including the Riot shield. If I load yours last I get the ICON but the error conflict is still there

you mean my HUD doesn't show up but riotshields spawns in game?

Well after some testing the other mod seems to disable the Riot shield somehow, but just a separate icon would be very awesome friendo :)

@Masterman I see now, it conflicts because the scripts he used also unlocks the riotshield in all main maps, now here's the thing... if the didgeridoo thingy spawns in your maps (or you can spawn them in the console) then don't mind the conflict it simply means his mod's scripts overwrites my scripts and you won't have any issue since he didn't put any file that touches the HUD of riotshield... but if either one of our mods don't work when used together let me know... I'll create a new mod that only changes the HUD and remove the scripts that unlock it in maps =w=

@Masterman Ok I'll thanks give it a look :)

Here ya go, others I found unlock both but icon issue, this one I believe unlocks just the didgeridoo
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2242197742&tscn=1601360078

@Masterman Can you link the mod that this conflicts with? i already have an idea why it conflicts but i can't really be sure to call it safe to use both until i could check what the conflict is

Currently torn, Been playing with Riot shield for years with other unlockers and since the update this is 100% the best one. But since the update the long lost didgeridoo is modded in and it conflicts with this mod. Not a modder so idk all the Jazz behind it.

But still much love this mod is great!

ViscerΔ hmm that's weird, last i checked i was sure the riot shield was untouched by the update, this was also confirmed by other mod creators as well. so technically it should not appear in vanilla game unless modded... but either way i updated this mod which makes it automatically add the riot shield in some of the main maps which i felt they were appropriate in ^-^

It adds the riot shield into the game
I played Last Man On Earth for fun, without any mods turned on (because I was offline at the time) and the riot shield kept popping up here and there
It was implemented into the game in some capacity
but it still uses the disgusting default knight shield icon :p

@言夜 我看一看, It's been awhile since i last played this game which means it's been longer that that since i last tried modding it. 所以我什么都不能保证 =w=

@ViscerΔ I'll try that ^-^ but from what I figured out, the Last Stand update doesn't really touch the riot shield. It only adds the hidden css guns and knife in the default roster. =-=

thank you so much
this should be the default icon in the actual game
maybe you should contact one of the Last Stand modders?
they could probably make it happen
