frame is what frame ur on, fps is obviously frames per second, frame to click is what frame you have to click on for the next action to happen (i just made it say u got it lol), the range is how far away from the exact frame you have to be to still get it right. play around with the variables and you could make a rhythm game.
all me. 33 blocks. got the idea from OSU and stuff it doesnt always work if the frames are going too fast though ;-; the fps is actually real.
