SDL_STANDARD_GRAVITY

A constant to represent standard gravity for accelerometer sensors.

Header File

Defined in SDL_sensor.h

Syntax

#define SDL_STANDARD_GRAVITY    9.80665f

Remarks

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.
