Friday Night Funkin' - Psych Engine EK+

Psych Engine EK+ (Extra Keys Plus) is a modded version of Psych Engine that uses refurbished code from a now discontinued project of a similar name.

The goal of this version is to keep up-to-date with Psych Engine and hopefully not lack any features added in newer versions, as well as eliminating some bugs from the previous version.

Installation:

You must have the most up-to-date version of Haxe, seriously, stop using 4.1.5, it misses some stuff.

Follow a Friday Night Funkin' source code compilation tutorial, after this you will need to install LuaJIT.

To install LuaJIT do this: haxelib git linc_luajit https://github.com/nebulazorua/linc_luajit on a Command prompt/PowerShell

...Or if you don't want your mod to be able to run .lua scripts, delete the "LUA_ALLOWED" line on Project.xml

If you get an error about StatePointer when using Lua, run haxelib remove linc_luajit into Command Prompt/PowerShell, then re-install linc_luajit.

If you want video support on your mod, simply do haxelib install hxCodec on a Command prompt/PowerShell

otherwise, you can delete the "VIDEOS_ALLOWED" Line on Project.xml

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 👀)
• 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.
• Multikey support:
  • You can choose how many keys (through 1-10) specific charts can have.
  • You can also dynamically change the amount of keys with the "Change Mania" event.
  • There is no support for 11 keys or more. You do not have more than 10 fingers.

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.
