The
followStrumfunction inNote.hxuses sin and cos funcions to change the incoming angle of the notes.That's good but the function calls those math functions and its a bit bad, so, instead of doing that, when
directionvariable change its value, caches the sin and cos of the angle, and thefollowStrumfunction uses it to prevent calling those functions every frame.
