"CANTBREATHE" is the manifestation of all beings fears. He maliciously seeks out his victims, wishing to cause and inflict unbearable pain to them. There is no real escape from this being, and you are never truly safe.

This mod is a remake of the older versions of "CANTBREATHE" by ClouddyVR,
because people weren’t fans of the red fleshy design or its repetitive dweller ai. 
So this mod brings back the classic spooky black figure, gives him decently advanced ai,
and a new model with horns, cause what being called the 'incarnation of fear' wouldn't have horns?

for people who came from pandeh's video, he explained the purpose of the mod pretty badly, and
even used the shitty outdated model.
please read the modpage before giving your opinion!

What he does:

Normal "CANTBREATHE"

He spawns every 3-6 nights (configurable).

He will slowly walk to you, while stopping every 10 seconds,
then begins moving again after 5 seconds of being still.

If you spot him or you get into a 32 block radius,
it triggers a cutscene similar but not the same as the Cave Dweller's "spotted".

You will have 15 seconds to run as far away as you can before he eventually
roars loudly and gives chase.
 if he catches up to you he holds you in place and
impales your head with his arm (instakill, configurable).

After you die, if theres another player in a 48 block radius he turns to chase them (configurable),
repeating the cycle if there are multiple players, else he despawns.

He despawns after 30 seconds (configurable),
but the timer multiplies by 2 when a player is killed.
example: he kills a player when theres 24 seconds left, now he has 48 seconds left,
so split up your group when he gives chase or else you're all probably going to die.

Silent "CANTBREATHE"

He spawns every 1-5 nights (configurable).

This variant is essentially cantbreathe but creepy, but overall less hostile,
has creepier sounds, a creepier look, and most notably the eyes are gone.

When he spawns, you will hear unnerving noises meant to instill fear,
and his 2 variants of AI are randomly picked to spawn.

AI : Levitator

Slowly levitates to you, arms reaching in a ghostly manner while a creepy
sound loops while it gets louder and louder as he gets closer.

But he doesnt stay slow.

He gets faster the closer he is to his target.

He reaches his max speed at a 16 block radius, a speed of 0.48.

For reference, the top speed of a player is 0.36 while sprint jumping.

If he catches you, a jumpscare will pop up instantly killing you.

He despawns after 2 minutes, or if he kills a player.

AI : Stalker

Heavily inspired from "Disturbed" mod.

This variant spawns behind you and makes a creepy noise,
and it will stalk 3 blocks behind you at all times, trying to avoid eyesight.

If you spot him behind you, a jumpscare will pop up but it doesn't kill you.
However, if you dont notice him for 1 minute (configurable) his hands
will slowly creep in from the sides of the screen and this time a jumpscare
pops up that instakills you.

How to defeat him:

Unavailable, will add again in v1.1.0
If you want the bossfight back, then use v0.2.1b

How to configure him:

There will be a file named "cantbreathe_asphyxation.toml" in your config folder.

"spawnmin" is the minimum amount of ticks he takes to start spawning.

"spawnmax" is the maximum amount of ticks he takes to start spawning.

"disappeartimer" is the amount of ticks he takes to despawn when aggressive.

"spottedradius" is the amount of how sensitive he is to getting looked at.
this is the block radius you have to look at for him to get aggressive,
think of it like a cube hitbox around him, if you look at that hitbox
he will get aggravated. this config allows you to change the size of that hitbox.

"instakill" a toggle for instead of the kill cutscene, it is replaced with normal damage.

"damage" only works if you have instakill set to false

"silentspawnmin" is the minimum amount of ticks the silent variant takes to start spawning.

"silentspawnmax" is the maximum amount of ticks the silent variant takes to start spawning.

There are more configuration variables, but they don't work yet.
It will be fixed in a future mini-update.

Known bugs:

Ratin0104:
"ISSUE!!!! Silent version kill doesnt work with the Corpse mod, making you lose your items."

OpticM3KH:
"when i managed to kill the silent one, he still kills me long after i kill it."

OptimusDweller:
"PLZ FIX THIS CREATURE'S ABILITY TO DELETE INVENTORY!!!!!" (not intended)

Questions you'll probably ask, might be important!:

I encountered alot of bugs playing the mod, can you fix them?

please clarify in the comments or issues, at the time i need
all the help i can to get the mod into a stable state.

Where's 1.20.1?

It'll come soon, 1.19.2 is the base version of this mod. ports may come later as
some code breaks when porting the mod to newer versions.

Why do all of his variants instakill?

Cause it's based off the OG instakilling CANTBREATHE that alot of people liked,
so im trying to implement instakill into this mod where its as fair as instakill can be.
Fair as in it can be avoidable, the normal variant gives you 15 seconds to run
as far away as you can or set up anything that can help you avoid him,
and both of the silent variants are easily avoidable and counterable.
