• \brief A structure containing a template for a Periodic effect. *
• The struct handles the following effects:
• - ::SDL_HAPTIC_SINE
• - ::SDL_HAPTIC_LEFTRIGHT
• - ::SDL_HAPTIC_TRIANGLE
• - ::SDL_HAPTIC_SAWTOOTHUP
• - ::SDL_HAPTIC_SAWTOOTHDOWN *
• 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:
• - 0: No phase displacement.
• - 9000: Displaced 25% of its period.
• - 18000: Displaced 50% of its period.
• - 27000: Displaced 75% of its period.
• - 36000: Displaced 100% of its period, same as 0, but 0 is preferred. *
