#include <SDL_haptic.h>
A structure containing a template for a Periodic effect.
The struct handles the following effects:
A periodic effect consists in a wave-shaped effect that repeats itself over time. The type determines the shape of the wave and the parameters determine the dimensions of the wave.
Phase is given by hundredth of a degree meaning that giving the phase a value of 9000 will displace it 25% of its period. Here are sample values:
Examples:
