After adding the ability to twist and curve the track, I needed to update the player movement script to take those changes into account. The player’s position and rotation are now effected by which part of the track they are on, as you can see below.
I also added the ability for the player to dodge left and right by double tapping a direction key.
Finally I added controls for how much acceleration power and braking power the player has. This way we can tweak both values separately and even adjust them in scripts (for example for a speed boost, or for an EMP which disables your brakes momentarily)
