Point system
Calculating points correctly is highly important to ensure a fun and balanced game. We adopt GeoGuessr's 5000 point approach, based on the maximum distance possible and an exponential decay function.
In WorldGuessr, points are implemented in components/calcPoints.js

| Parameter | Type | Description |
|---|---|---|
| lat | Number | Latitude of the actual location. |
| lon | Number | Longitude of the actual location. |
| guessLat | Number | Latitude of the guessed location. |
| guessLon | Number | Longitude of the guessed location. |
| usedHint | Boolean | Indicates if a hint was used during the guess. |
| maxDist | Number | Maximum distance of any 2 points in the chosen map (in km). Pass in 20000 when playing the World map |
Hints are allowed only in singleplayer, mainly to help new players gain intuition for the game. It draws a circle containing the correct answer (make sure to not put the correct answer in the center as it makes it obvious!)
It affects their points by a scale factor of 0.5 (divides their points by 2)
For the specific implementation of the hint system on the map, refer to components/Map
