**Doors** are one of the major structures of the *Baldi's Basics* series, allowing access to different locations, like classrooms and faculty rooms. The doors also play a crucial role for Baldi to find the player's location just by the sound of a door opening. The player can open the doors by left-clicking or touching the  button while facing them.

When a door is opened, it will automatically close itself after 3 seconds. However, the door can stay opened if the player interacts with it constantly.

During the flood event, every door in the Super Schoolhouse will stay open, giving the player a chance to enter any room without being heard by Baldi (unless he sees the player).

A special door type, called a swinging door, has a few different designs that function as obstacles. They do not open even during the flood event.

## Types

There are six different types of standard doors: **class door**, **faculty door**, **supplies door**, **Baldi door**, **placeholder door**, and **mystery door**. The WD-NoSquee item can be used on these doors to make them silent, preventing them from being heard by Baldi. The Principal's Keys can be used on doors locked by Chalkles or Mrs. Pomp or during detention. The texture of the door depends on the room it leads to.

### Common doors

Only two types of **common doors** are found, and mostly connect to common rooms such as classrooms and faculty rooms.

#### Class doors

**Class doors**, or **blue doors**[*citation needed*], are very common and usually connect to classrooms where the player can find notebooks. All characters can open blue doors. Blue doors also connect to the Principal's office. All class doors have the number 99, the number found and heard several times.

#### Faculty doors

**Faculty doors** appear to be wooden with the words "**School Faculty Only**" written on it. They lead to faculty rooms where the player can find more useful items such as Energy Flavored Zesty Bar or Portal Poster.

If the player enters, exits, or stays inside a faculty room near Principal of the Thing, they will get placed in detention, unless the Faculty Nametag item is in action. Unless directly entering the room, opening the front door while the Principal is there does not count as a school rule violation.

### Unique doors

**Unique doors** are only found connected to special or hidden rooms.

#### Supplies door

A **supplies door**, or **closet door**\*, is the door exclusively used on Gotta Sweep's closet. Unlike the common doors, the door knob is attached to the left, so it opens towards the right side.

#### Mystery door

The **mystery door** is a green door printed with multi-colored 3D question marks. It will appear as a part of the mystery room random event.

#### Baldi door

The **Baldi door**, or **green door**[*citation needed*], is exclusive for Baldi's Office in *Baldi's Basics Classic*, *Birthday Bash*, and *Classic Remastered*. The door has text that reads: "Baldi's Office".

When opened in *Baldi's Basics Classic* and *Birthday Bash*, the opened section of the door for Baldi's Office is not transparent, and instead, distorted. Therefore, it looks like a stretched out image of the brick wall. This happens because the checkbox was not enabled with Alpha is Transparency in Unity. The player can still pass through the door because the door collider would be still on.

In *Classic Remastered*, the door looks normal when it is opened.

#### Placeholder door

A **placeholder door** is a blue door with red "**DOOR**" text written vertically. This door is used for the debug room. Like the supplies door, the placeholder door opens on the right side.

## Trivia

### General

* All doors are not models but just 2D textures with collision; there are two textures for each door (open and closed), with the exclusion of swinging doors, which also have the locked texture, and the dark open, closed, locked, the coin door texture, and the right and wrong way textures, which totals 6 textures compared to 2 for standard doors.
* The faculty doors are created by using a pre-existing pattern in GIMP.
* The doors have the same image size as the *Sonic's Schoolhouse* door images.
* Prior to the *Kickstarter Exclusive Demo*, each door's back texture is the same as its front's.
* The supplies door and the Baldi door do not have dithering unlike all other door types.

### *Baldi's Basics Plus*

* Sometimes, the door has different textures on each side. This is intended to represent the type of room that is on the other side.
	+ The similar thing can happen in *Classic Remastered*. However, only faculty rooms and Gotta Sweep's closet will have the classroom door on the back of it, where it connects to a hallway.
* Prior to V0.1.3, the door did not make a sound when NPCs such as Baldi open it.
* Prior to V0.2, the door to Gotta Sweep's closet was a placeholder door.
* Prior to V0.3.3, the door to the Gotta Sweep's closet in the Grapple Challenge was a placeholder door.

### *Baldi's Basics Classic*

* There are 24 doors altogether in the classic Schoolhouse.
	+ However, if the door to Baldi's Office is counted, there will be 25 in total.
* Prior to V1.4, if the player was standing in a standard doorway and was caught by Playtime, the player would escape the minigame as soon as the door closed, and Playtime would wander off as if the player had jumped all five times. This was due to how collision worked.
* If Principal of the Thing opens a door and the player clicks on the door, it will still make the door opening sound while opened, and alert Baldi as if they are opened a regular door.

### *Baldi's Basics Birthday Bash*

* There are 8 doors in the glitched school.

### *Baldi's Basics Classic Remastered*

* There are 4 doors in Baldi's Basement, which are all faculty doors.
* There are 2 doors in mystman12's Office, one is a classroom door, and the other is a supplies door.

### *Baldi's Basics Full Game Early Demo*

* There are 14 doors in the Super Schoolhouse.

## Glitches

* Starting from December 2018, there is a very rare chance that the door sound plays twice in a row whenever opening or closing.
