To find out more about what drifting is and how to do it read [Drifting Techniques](Drifting_techniques.md). Overview -------- The player's drift score is displayed on the left side of the screen, underneath the lap timer box. Start of scoring ---------------- The game starts drift scoring when a car satisfies the following conditions, - At least **2** of the wheels are on track, and - Car speed is above **10 m/s**, and - The drift angle (angle between car's orientation and its velocity direction) is more than **0.2 radian** (about 11.5 degrees), and less than **PI/2** (i.e. spin out). End of scoring -------------- The drift scoring ends when either one the following occurs, - Less than **2** wheels are on track, or - Car speed is less than **10 m/s**, or - The drift angle is less than **0.1 radian** (about 5.7 degrees) Scoring rules ------------- At the beginning of a drift, the game starts accumulating the score for this drift. At the end of a drift, the accumulated score is added to the total score. The accumulated score consists of base score and bonus score; - **Base score** - This is simply the length the car has travelled in this drift (in meters). A longer drift will earn higher base score. - **Bonus score** - This contains 3 components: - **drift length bonus** - same value as the base score, effectively giving double bonus to longer drifts. - **maximum drift speed bonus** - the value is the maximum drift speed (in m/s) / 2 - e.g. a maximum drift speed of 20 m/s will earn a bonus of 10. - **maximum drift angle bonus** - the value is the maximum drift angle (in radian) * 40 / PI - e.g. a maximum drift angle of PI/4 (45 degrees) will earn a bonus of 10. If the car goes off track or spins out during a drift, the accumulated drift score is not added to the total score. An accumulated drift score of less than 5 is not added to the total either.
