Rave Cage Carnage.
Rave Cage Carnage (RCC) is a Rhythm-based action slasher with
roguelike progression and dynamic intensity. For this game
I developed a beat detection script which should allow us to
Player inputs and objects to respond to the music.
My tasks:
-Gameplay Programmierer: Enemy K.I., Skillsets implemented, Items implemented.
-System Programmer: Beat detection script created. A script that allows us different objects respond to the beat of the music and match player input to the beat.
