Seed

Seeds are the mechanism used to randomly generate floors.

Description
A seed is a random string of numbers used in level-generating algorithms to procedurally generate and create each floor in Baldi's Basics Plus. After completing the Hide-and-Seek mode once, the player can choose to put in a specific seed or leave it blank to generate a random one. In Endless Mode's Random option, the player can input a custom seed, regardless of completing Hide-and-Seek.

Level-Building Algorithm Codes
When accessing the Baldi's Basics - Challenges Demo code via DnSpy, there is an algorithm for generating all the different types of locations:

Trivia

 * The seed for the Stealthy Challenge is listed as 99 in Challenges Demo.
 * There are exactly 4,294,967,231 possible seeds.
 * There can only be 10 digits in the seed number.
 * Prior to V0.1.1 of Baldi's Basics Plus, it was possible to enter a seed number lower than and higher than.
 * Prior to Baldi's Basics Plus V0.1.3, playing the game with the seed would crash the game, but since this version, it will select the random seed.
 * Some seeds generate debug rooms if there is no proper space to generate classrooms. Their color on the map is black like the library prior to V1.2 in the Kickstarter Exclusive Demo.
