| desiredAccuracyInMeters | The service accuracy you want to use, in meters. This determines the accuracy of the device's last location coordinates. Higher values like 500 don't require the device to use its GPS chip and thus save battery power. Lower values like 5-10 provide the best accuracy but require the GPS chip and thus use more battery power. The default value is 10 meters. |
| updateDistanceInMeters | The minimum distance, in meters, that the device must move laterally before Unity updates Input.location. Higher values like 500 produce fewer updates and are less resource intensive to process. The default is 10 meters. |
Starts location service updates.
After you call this function, you can access the device's last location coordinates.
To do this, check lastData in Input.location.
Note: The location service doesn't start to send location data immediately. Check status in Input.location for the current service status.
On Android, using this method in a scripts automatically adds the ACCESS_FINE_LOCATION permission to the android manifest. If you use low accuracy values like 500 or higher, you can select Low Accuracy Location in Player Settings to add the ACCESS_COARSE_LOCATION permission instead.
