Module fermium::sensor

Lets SDL use various sensors (such as the accelerometer in a phone).

SDL_Init must have been called with the SDL_INIT_SENSOR flag. This causes SDL to scan the system for sensors, and load appropriate drivers.

Structs

• SDL_Sensor
  SDL’s opaque sensor type.
• SDL_SensorID
  This is a unique ID for a sensor for the time it is connected to the system.
• SDL_SensorType
  The different sensors defined by SDL

Constants

• SDL_SENSOR_ACCEL
  Accelerometer
• SDL_SENSOR_GYRO
  Gyroscope
• SDL_SENSOR_INVALID
  Returned for an invalid sensor
• SDL_SENSOR_UNKNOWN
  Unknown sensor type
• SDL_STANDARD_GRAVITY
  Accelerometer sensor

Functions
