    Any extra info left out will be in this comment and will be updated! -The Death Minigames have a 10% chance to occur everytime you die and each game has a 25% chance to occur -The Puppet has a 1 in 10 chance every second to kill you after they leave the box

    10% chance after death is correct, each game being a 25% chance is incorrect because they play in a specific order, and Puppet's 1/10 chance only applies when they actually reach the office

    1 in 10 chance for puppet to kill you after leaving the box?so you tell me if she leaves the box im dead the next second?On the older version of fnaf 2 on android that would be correct but on pc i noticed its between 5 and 10 seconds after she leaves the music box.On older versions of fnaf 1 and fnaf 2 u die instantly after freddy power outage happens in fnaf 1 or puppet leaves the music box in fnaf 2.

    The puppet doesn't actually have a limit on how long she takes to get to your office, she uses MO's like everyone else, but the chance of her killing you in the office is 1/10 every second, so theoretically she could be out for the entire night and not kill you, but this chance is super super super low. Also, toy bonnie's chance to move is always 0.5s regardless of where anyone is, the 1/3 chance is for when you're actually in a blackout with a withered animatronic or toy freddy. Mangle and BB also work slightly differently than toy chica, TC has to be waiting for 6 seconds in the vent in order to attack you on a cam flip, whereas mangle and BB get in instantly on the next cam flip. W freddy is also slightly different from the other withered animatronics, for some strange reason he has a mechanic that gives him a chance to leave while in the main hall when the mask is on, which is why you don't see him that often in 10/20. I had no idea about the secret mechanics and characters tho, never seen anyone talk about that

    Also, when the Marionette leaves Prize Corner, he actually uses a similar movement opportunity like most of the animatronics. However, instead of having a chance to move every 5 seconds, the Marionette has a chance to move every 1 second. If the Marionette's A.I. is greater than or equal to the random number that's generated, then he'll move to his next position. The Marionette's movement pattern, albeit invisible, is the following: Prize Corner > Game Area > Main Hall > Party Room 3 or Party Room 4 > Party Room 1 or Party Room 2 > Office (DEATH)

  • @jerakaigamez

    You are correct that its every second however there is no movement pattern, it's simply a 1 in 10 chance every second that they will kill you. The puppet doesn't run on random numbers like the rest their AI is set per night. Otherwise the puppet would kill you faster on later nights which from our testing isn't true

    @aaronhjones8711 Marionette does indeed have a path, you are right. Jerkai is getting confused because they apparently only went off testing the time of death instead of actually looking at the code. The 1/10 chance applies only when the Marionette actually _reaches the office._ Being able to see the Marionette hallucinations on the cameras is entirely possible _because_ he's actually stationed on that camera after escaping. Also, you may have intended this, but I'll say it anyway for clarity. Once the Marionette goes on his split path after the Main Hall, it's either Party Room 3 -> Party Room Room 1 -> Office *OR* Party Room 4 -> Party Room 2 -> Office. He doesn't switch which side he's on after already picking left or right.

    not to mention he is the most aggresive if u have less than 5 animatronics in night 7 is alternate d value will always be high meaning that if u put your mask on even for one second after u flashed him 15 times(happened to me on foxy foxy night)you will die by him

  • @BlueGhostGamer95
    @BlueGhostGamer953 күн бұрын

    I've been reading after FNAF2 breakdowns for a while, and this is what I've figured out about Withered Foxy, after reading a butload of discussions: So the formula is obvious. Alterable Value D goes up by 1 every second if no threats are present and a further one if you wear the mask without animatronics in the vent blindspots. It goes down by 1 every 0.5 second if the light is on the hallway. It freezes during a blackout phase, but movement opportunities can succeed. If Foxy in this stage has a movement opportunity succeed, he gets to the hall before you. Every time you shine the flashlight on him his stun timer resets to 50 frames (0.83s), and his Alterable Value D goes back to 0. So basically, he's frozen for 0.83s after shining the light on him and the timer that murders you is reset. If during this, he succeeds a movement opportunity, you die. However, once you shine the light on him for 100*NightNumber+1 frames in total, all his numbers are reset, baring the stun timer, which is randomized between 500-1000 frames (8.33s - 16.67s) and he retreats to Parts&Service, repeating the cycle. This explains why he can be active on AI level 0, as Alterable Value D can get so high, that it activates Foxy no matter what. Till 1am of Night 2 of game progress, this is hard coded to 0 Also, the puppet's music box winds up by 5 every tick, except when it's below 300, in that case it instantly goes to 300

    Do you mean the blackout happened but nobody was there, or he literally attacked out of nowhere? If 2nd case, I think he can attack from the hall if you are using the camera while he is there, so he may have just attacked since you didn't pull the monitor down for a while.

    Hi there! There’s a couple of things I’d like to ask about the movement opportunities system if you wouldn’t mind. Oh, and by the way: the body of text at 2:06 is -probably- technically wrong. I’m assuming you just got it mixed up and that slipped past editing. 1. Does the game roll one number and have that number be compared to every animatronic’s AI level or does it roll a number for each animatronic? I.e does the game roll a number like “8” and any animatronic with a number higher than that moves or does it roll a number like “6” for Freddy, “14” for Bonnie, etc? 2. If the number is equal to the AI level, do they still move? I know you verbally said that they’ll move but the text being wrong is tripping me up a bit 3. Can the game roll a 0 or is it just 1-20? I’m assuming it doesn’t but just making sure.

    Doesn't seem wrong just may not be read correctly. 1. It rolls a random number for every character. Every character has a unique chance to move 2. Yes if the ai is equal to the number they will move 3. No 0 is not in the number pool. Otherwise they could move while inactive
