// SVEN-COOP AUTOSPLITTER
// VERSION 1.1 - 2021/03/28
// GAME VERSIONS TESTED: 
// - Latest Steam version as of 2021/03/28
// - The version released on 2017/04/15
// - 2 versions from 2019 and one from 2016/09/03
// CREDITS:
// - 2838 for entity list functions, sigscanning functionality, reworks for all Auto-stops and some Auto-starts
// - SmileyAG for initial splitter codework
// - BenInSweden, Chillu and ScriptedSnark for additional code
// HOW TO USE: https://github.com/SmileyAG/Sven-Coop-Autosplitter/blob/master/README.md
// PLEASE REPORT THE PROBLEMS TO EITHER THE ISSUES SECTION IN THE GITHUB REPOSITORY ABOVE OR IN THE SVEN COOP DISCORD

// AUTO-STARTS TRIGGERS:
// - Uplink: when the player gets teleported outside the starting area
// - Other games: when the loading int changes from 1 to 0 and the map is correct

// AUTO-ENDS TRIGGERS
// - HL1: when Nihilanth's hp drops below or equal 0
// - They Hunger:
//	+ EP1: when the next think time of the ending multimanager entity goes above 0
//	+ EP2: when the valve's angular velocity goes from 0 to 40
//	+ EP3: when the final boss' hp drops below or equal 0
// - OP4: when the button's animation playback rate goes from 0 to 1
// - Uplink: when the hp of the vent at the end goes from 1 to 0
