SDL2::HapticPeriodic - A structure containing a template for a Periodic effect
use SDL2 qw[:all]; # TODO: I need to whip up a quick example
A SDL2::HapticPeriodic contains 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
9000
18000
27000
36000
