SDL_RunHapticEffect

Run the haptic effect on its associated haptic device.

Header File

Syntax

bool SDL_RunHapticEffect(SDL_Haptic *haptic, int effect, Uint32 iterations);

Function Parameters

SDL_Haptic *	haptic	the SDL_Haptic device to run the effect on.
int	effect	the ID of the haptic effect to run.
Uint32	iterations	the number of iterations to run the effect; use `SDL_HAPTIC_INFINITY` to repeat forever.

Return Value

(bool) Returns true on success or false on failure; call SDL_GetError() for more information.

Remarks

To repeat the effect over and over indefinitely, set iterations to SDL_HAPTIC_INFINITY. (Repeats the envelope - attack and fade.) To make one instance of the effect last indefinitely (so the effect does not fade), set the effect's length in its structure/union to SDL_HAPTIC_INFINITY instead.

Version

This function is available since SDL 3.1.3.
