JS Engine
JS Engine is a heavily modified Psych Engine fork I made, with lower-end PCs and more customization in mind while also aiming to be a replacement for OS Engine.
WARNING: SET HXCODEC TO 2.5.1 TO FIX CRASHES WITH EXTRA KEYS WITH LUA SCRIPTS
FEATURES IN JS ENGINE:
This fork of psych engine 0.6.3 has lots of features, even more than OS ENGINE!
The engine:
- Can load notes more than 100k instead of closing the window
- Can load longer than 20m30s songs
- Has lots of optimization
- Can chart bambi songs EASIER
- Has basic shader support (such as
addGlitchEffect, addChromaticAbberationEffect, and more!)
- Can turn your bad pc into a better pc if you are having trouble lagging hard in the base one.
- Is spam friendly
- Has some cool features you might want to try it out
- Uses 0.6.3 instead of the new ones (such as 0.7.3)
(and possibly more stuff that will be listed here...)
FAQ
Q: Can I use this engine for my mod(s)?
A: Yes, you can! just be sure to credit me (@JordanSantiago on YouTube) and give a link to this page. or the link to download the latest release.
Q: How do I (change the background, add characters, etc.)?
A: You do it here the same way you'd do it in Psych Engine.
Installation:
You must have the most up-to-date version of Haxe, seriously, stop using 4.1.5, it misses some stuff.
If you don't have Microsoft Visual Studio Community installed, install it. While running the installer, make sure to check the following two:
MSVC v142 - VS 2019 C++ x64/x86 build tools (Version doesn't matter)
Windows 10/11 SDK (Any version)
The source code should come with a "Quick SETUP" batch file. Run it in order to install all the needed libraries for JS Engine!
If you get an error related to hxCodec, run haxelib set hxCodec 2.5.1
If graphics are all white and don't have color, run haxelib set hxcpp 4.2.1
Customization:
if you wish to disable things like Lua Scripts or Video Cutscenes, you can read over to Project.xml
inside Project.xml, you will find several variables to customize JS Engine to your liking
to start you off, disabling Videos should be simple, simply Delete the line "VIDEOS_ALLOWED" or comment it out by wrapping the line in XML-like comments, like this <!-- YOUR_LINE_HERE -->
same goes for Lua Scripts, comment out or delete the line with LUA_ALLOWED, this and other customization options are all available within the Project.xml file

# Features
## Attractive animated dialogue boxes:
## Mod Support
* Probably one of the main points of this engine, you can code in .lua files outside of the source code, making your own weeks without even messing with the source!
* Comes with a Mod Organizing/Disabling Menu.
## Atleast one change to every week:
### Week 1:
* New Dad Left sing sprite
* Unused stage lights are now used
### Week 2:
* Both BF and Skid & Pump does "Hey!" animations
* Thunders does a quick light flash and zooms the camera in slightly
* Added a quick transition/cutscene to Monster
### Week 3:
* BF does "Hey!" during Philly Nice
* Blammed has a cool new colors flash during that sick part of the song
### Week 4:
* Better hair physics for Mom/Boyfriend (Maybe even slightly better than Week 7's :eyes:)
* Henchmen die during all songs. Yeah :(
### Week 5:
* Bottom Boppers and GF does "Hey!" animations during Cocoa and Eggnog
* On Winter Horrorland, GF bops her head slower in some parts of the song.
### Week 6:
* On Thorns, the HUD is hidden during the cutscene
* Also there's the Background girls being spooky during the "Hey!" parts of the Instrumental
## Cool new Chart Editor changes and countless bug fixes
* You can now chart "Event" notes, which are bookmarks that trigger specific actions that usually were hardcoded on the vanilla version of the game.
* Your song's BPM can now have decimal values
* You can manually adjust a Note's strum time if you're really going for milisecond precision
* You can change a note's type on the Editor, it comes with two example types:
* Alt Animation: Forces an alt animation to play, useful for songs like Ugh/Stress
* Hey: Forces a "Hey" animation instead of the base Sing animation, if Boyfriend hits this note, Girlfriend will do a "Hey!" too.
## Multiple editors to assist you in making your own Mod
* Working both for Source code modding and Downloaded builds!
## Story mode menu rework:
* Added a different BG to every song (less Tutorial)
* All menu characters are now in individual spritesheets, makes modding it easier.
## Credits menu
* You can add a head icon, name, description and a Redirect link for when the player presses Enter while the item is currently selected.
## Awards/Achievements
* The engine comes with 16 example achievements that you can mess with and learn how it works (Check Achievements.hx and search for "checkForAchievement" on PlayState.hx)
## Options menu:
* You can change Note colors, Delay and Combo Offset, Controls and Preferences there.
* On Preferences you can toggle Downscroll, Middlescroll, Anti-Aliasing, Framerate, Low Quality, Note Splashes, Flashing Lights, etc.
## Other gameplay features:
* When the enemy hits a note, their strum note also glows.
* Lag doesn't impact the camera movement and player icon scaling anymore.
* Some stuff based on Week 7's changes has been put in (Background colors on Freeplay, Note splashes)
* You can reset your Score on Freeplay/Story Mode by pressing Reset button.
* You can listen to a song or adjust Scroll Speed/Damage taken/etc. on Freeplay by pressing Space.
