SDL_SensorType

The different sensors defined by SDL.

Additional sensors may be available, using platform dependent semantics.

Here are the additional Android sensors:

Accelerometer sensor notes:

The accelerometer returns the current acceleration in SI meters per second squared. This measurement includes the force of gravity, so a device at rest will have an value of SDL_STANDARD_GRAVITY away from the center of the earth, which is a positive Y value.

- values[0]: Acceleration on the x axis - values[1]: Acceleration on the y axis - values[2]: Acceleration on the z axis

For phones and tablets held in natural orientation and game controllers held in front of you, the axes are defined as follows:

- -X ... +X : left ... right - -Y ... +Y : bottom ... top - -Z ... +Z : farther ... closer

The accelerometer axis data is not changed when the device is rotated.

Gyroscope sensor notes:

The gyroscope returns the current rate of rotation in radians per second. The rotation is positive in the counter-clockwise direction. That is, an observer looking from a positive location on one of the axes would see positive rotation on that axis when it appeared to be rotating counter-clockwise.

- values[0]: Angular speed around the x axis (pitch) - values[1]: Angular speed around the y axis (yaw) - values[2]: Angular speed around the z axis (roll)
