Is it normal that it disables my means of finding the dead locked up?

ツ Apparently, I forgot to add the link to the guide while I was editing my comment. Nevertheless, you can set up a local Versus server to use this add-on. Here's the guide that'll show you how to modify the `addonconfig.cfg` file in the `./left4dead2/cfg/` directory.

Can it be done if the vpk method is used?
Taut  [author] 2 May @ 6:00pm 
ツ Since this add-on uses VScripts, the only way you can use it in Versus would be to set the value of the `versus` variable underneath `RestrictAddons` to `0` and then create a local server. For more details, you can view this guide which shows you how to enable add-ons in Versus on local servers.

works on vs?

@exactly 1 knight If you want to play campaigns as if it were Versus, then I recommend installing the `Special Infected Synchronization (Competitive)` add-on instead as the `MaxSpecials` option is set to `4` by default which will allow up to four special infected to spawn at once.

Is making all 4 special infected spawn at the same time as simple as changing "MaxSpecials" to 4? I wonder if you could pseudo-recreate a VS mode like experience this way? (Without the kicking and racial slurs, of course.)
Taut  [author] 5 Mar @ 1:47pm 
@Sasha Pines (no brain) At one point, the `MaxSpecials` variable was set to `3` as I figured that three special infected normally spawned in official campaigns. However, I realized that the third special infected only spawned as soon as one of the active special infected was killed.

Because I figured that some campaigns would modify either the `cm_MaxSpecials` or `MaxSpecials` variable at certain times (ex. the finale in Chapter 3 of The Passing), I let the Director handle those two variables automatically instead of manually setting them at specified values.
Sasha Pines (no brain) 5 Mar @ 6:22am 
question why there only 2 si spawn at a time instead 4 like older version i renember ?

@Wenda I don't think this add-on has any impact on the amount of Witches that spawn in a map.
I STAPLE TAPEWORMS ON MY 26 Feb @ 8:22pm 
does this increase the amount of witches per map?
I STAPLE TAPEWORMS ON MY 23 Feb @ 2:01pm 
oh thank you
Taut  [author] 23 Feb @ 1:59pm 
@Wenda I played the first chapter of The Passing with this add-on disabled, and the Tank still spawns before I reached the primary weapons. The only difference I encountered is that the Tank didn't attack until I actually saw him because the `cm_AggressiveSpecials` variable is normally set to `false` by default.

If you want an easier time going against the Tank in the first chapter of The Passing, I recommend setting the `AllowAggressiveSpecials` option in the `settings.txt` file to `false` so he doesn't immediately attack as soon as he spawns.
I STAPLE TAPEWORMS ON MY 21 Feb @ 4:00am 
also with multiple witches spawning a map
I STAPLE TAPEWORMS ON MY 21 Feb @ 3:26am 
im having an issue on some campaigns where a tank can spawn a lot earlier than he should
examples being on the passing before you can get to the tier 1 guns or during the intro of cold stream
I STAPLE TAPEWORMS ON MY 21 Feb @ 3:20am 
does this effect tank spawns at all?
thanks to your detailed explanation! :krstar::krstar::krstar::krstar::krstar:

@.√ᴇɴℊᴇᴀɴᴄᴇ While this add-on doesn't disable the Charger's damage resistance during his charge animation, the `Special Infected Synchronization (Competitive)` add-on includes the `ModifyChargeHealth` option in the `settings.txt` file located in the `./ems/sisync-comp/` directory which will allow the Charger to take normal damage while charging.
does this script disable the 66% melee attack resistance on Charger? (while in charging)

@Destructible Dummy After looking through my VScripts in this add-on, it turns out the `DynamicSpecialTimer` option wasn't actually in the `settings.txt` file. I'll have to update this add-on to resolve this issue.
Destructible Dummy 13 Feb @ 7:51am 
Instead of actually working, it got me an error:

There's an error whenever I change the variable in the settings confg:

InitialSpawnDelayMax = 120
InitialSpawnDelayMin = 60

OverrideInitialSpawnDelay = true
OverrideRespawnInterval = true
RespawnIntervalMax = 60
RespawnIntervalMin = 60

Additionally, I've tested without some addons that modifies Special AI like (Competitive Bots), yet again, it's not working for some reason; deleting the ems file is a thing to reboot this issue but its still persists. Thank you:health:
Rtma Eros Paragon 7 Feb @ 9:48pm 
Thanks for the information, I am testing those now.
Taut  [author] 6 Feb @ 6:20am 
@Rtma Eros Paragon You can modify the options in the `settings.txt` file located in the `sisync-ai` folder.

As for the mob and special directions, here are the options the numbers are referring to according to the Director Scripts wiki page :
---
SPAWN_NO_PREFERENCE = -1
SPAWN_ANYWHERE = 0
SPAWN_BEHIND_SURVIVORS = 1
SPAWN_NEAR_IT_VICTIM = 2
SPAWN_SPECIALS_IN_FRONT_OF_SURVIVORS = 3
SPAWN_SPECIALS_ANYWHERE = 4
SPAWN_FAR_AWAY_FROM_SURVIVORS = 5
SPAWN_ABOVE_SURVIVORS = 6
SPAWN_IN_FRONT_OF_SURVIVORS = 7
SPAWN_VERSUS_FINALE_DISTANCE = 8
SPAWN_LARGE_VOLUME = 9
SPAWN_NEAR_POSITION = 10
Rtma Eros Paragon 6 Feb @ 2:44am 
I still do not know what the numbers used for direction of mobs/si and a descriptive list to choose from.
Rtma Eros Paragon 6 Feb @ 2:25am 
Which file actually applies the settings? the one in the aisync-ai folder or cfg?
Taut  [author] 29 Nov, 2024 @ 12:39pm 
@Dread-Captain Ephrer Atargrius That's not good. I've tried running this add-on without any other add-ons enabled and special infected were able to spawn after waiting for the initial spawn delay to be met (usually 30-60 seconds).

In the meantime, could you check the console by pressing the ` key to see if any errors pop up? Afterwards, could you try disabling all your other add-ons besides this one to see if specials are able to spawn? If they do spawn, could you also try re-enabling each one to find the culprit?
DaddyFlapJacks 27 Nov, 2024 @ 9:41pm 
for some reason this made no special infected spawn at all for me
im not sure what the issue is, no conflicting mods
Tri Tran 31 Aug, 2024 @ 10:10pm 
Thanks for the details :steamthumbsup:
Taut  [author] 31 Aug, 2024 @ 7:42pm 
@Tri Tran The `MaxSpecials` option isn't available for this add-on which is why the option you're trying to add will be removed when the map loads. If you want to modify the `MaxSpecials` option, I recommend using the `Special Infected Synchronization (Competitive)` add-on instead especially since it contains many more options in the `./ems/sisync-comp/` directory.

As for `z_tank_speed 240`, the add-on will simply modify command variables if they exist in-game which is how you're able to add new ones to the `convars.txt` file.
Tri Tran 31 Aug, 2024 @ 7:24pm 
Hello, why I cannot add "MaxSpecials" to "/ems/sisync-ai+/settings.txt"? It will restore default.
but, i can add "z_tank_speed 240" to "convars.txt"
Taut  [author] 24 Jun, 2024 @ 11:33pm 
@☣ROBLOX, NwiKing☣ Yes, setting the `ShouldAllowSpecialsWithTank` option in the `settings.txt` file located in the `./ems/sisync-ai+/` directory will allow the special infected to spawn while the Tank is active.
☣ROBLOX, NwiKing☣ 24 Jun, 2024 @ 11:19pm 
ShouldAllowSpecialsWithTank = true right?
Tri Tran 22 Jun, 2024 @ 7:49pm 
I trust you'll address the issue promptly. Thank you. :steamthumbsup:
Taut  [author] 20 Jun, 2024 @ 8:54am 
@Tri Tran That's not good. I'll have to look into this.

Please, help me! SI don't' appear in campaign
Taut  [author] 13 Jun, 2024 @ 12:54pm 
@Xeno :] That depends on the campaign you're playing and whether the Director decides to modify either the `MaxSpecials` or `cm_MaxSpecials` variable. For instance, The Passing's final chapter will set the `MaxSpecials` variable to `5` once the finale begins and will be changed to `3` during Tank fights.

(^^^) Xeno 13 Jun, 2024 @ 10:44am 
So it would be random sometimes it could be 2 or 4 SI will appear?
Taut  [author] 13 Jun, 2024 @ 8:51am 
@Xeno :] I decided to let the Director automatically handle the amount of special infected for the `Only Sync` and `AI+` version since I originally wanted these add-ons to synchronize their spawns without changing the gameplay too much.
(^^^) Xeno 13 Jun, 2024 @ 4:30am 
Little confused but only 2 of the SI attack or spawn at the same time on my pov
☣ROBLOX, NwiKing☣ 9 Jun, 2024 @ 11:20pm 
Thanks a lot :)
Taut  [author] 9 Jun, 2024 @ 11:20pm 
@☣ROBLOX, NwiKing☣ After thinking about it for a while, I could probably add an option to change the `ShouldAllowSpecialsWithTank` variable in a future update.
☣ROBLOX, NwiKing☣ 7 Jun, 2024 @ 2:59am 
But i dont want versus gameset what should i do?
Taut  [author] 6 Jun, 2024 @ 8:06pm 
Unfortunately, the `MaxSpecials` variable doesn't exist in this version. Even if the option was in the `settings.txt` file, that wouldn't allow the special infected to spawn while the Tank is active.

To allow the special infected to spawn, you would need to set the `ShouldAllowSpecialsWithTank` variable to `true`. While the option to do so isn't in the `settings.txt` file for this add-on, it's available for the `Competitive` version which you can find in the `Special Infected Synchronization Bundle`.
☣ROBLOX, NwiKing☣ 6 Jun, 2024 @ 10:06am 
I think when tank appears, special aren't spawned so I added MaxSpecialsTank = 4 in setting.txt
will it work?
Taut  [author] 29 Apr, 2024 @ 4:53am 
@Rtma Eros Paragon The numbers determine what type of direction the special infected will spawn from. For instance, setting the `PreferredMobDirection` variable to `7` will set it to `SPAWN_IN_FRONT_OF_SURVIVORS` which will make the special infected prefer to spawn ahead of the survivors if they're able to.

If you'd like to know what other options are available for the `PreferredMobDirection` variable, you can view its description at this wiki page .
Rtma Eros Paragon 29 Apr, 2024 @ 4:22am 
What numbers for and what do they do for PreferredMobDirection?
Taut  [author] 27 Apr, 2024 @ 12:05pm 
@Rtma Eros Paragon Here are the definitions for some of the available options in my add-on:

- The `OverrideMobDirection` option determines whether to allow the `PreferredMobDirection` option to override the variable set by the `SessionOptions` table. Currently, there isn't a special infected equivalent for overriding the directions they spawn at, but I could probably add that feature in the future.
- The `ThinkInterval` option controls how often the VScript's functions get updated. Setting it to `-1` will make them get updated at every available tick.
- The `LastSpawnedTime` option determines the amount of time the special infected can still spawn individually before they are no longer allowed to spawn.

If you'd like to know what the rest of the options do, you're free to take a look at this thread .
Rtma Eros Paragon 27 Apr, 2024 @ 1:02am 
In settings you got preferred mob and special directions override, what does that do and what are the variables you can use? think interval? last spawned time?
Lenar 9 Apr, 2024 @ 6:31am 
And when I hardly ever see them, they spawn in couples
