Update the properties of an effect.
int SDL_HapticUpdateEffect(SDL_Haptic * haptic, int effect, SDL_HapticEffect * data);
|haptic||the SDL_Haptic device that has the effect|
|effect||the identifier of the effect to update|
|data||an SDL_HapticEffect structure containing the new effect properties to use|
Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
Can be used dynamically, although behavior when dynamically changing direction may be strange. Specifically the effect may re-upload itself and start playing from the start. You also cannot change the type either when running SDL_HapticUpdateEffect().
This function is available since SDL 2.0.0.
