al_install_haptic(1) Allegro 5 API


#include <allegro5/allegro.h>
bool al_install_haptic(void)


Installs the haptic (force feedback) device subsystem. This must be called before using any other haptic-related functions. Returns true if the haptics subsystem could be initialized correctly, false in case of error.

For portability you should first open a display before calling al_install_haptic(3alleg5). On some platforms, such as DirectInput under Windows, al_install_haptic(3alleg5) will only work if at least one active display is available. This display must stay available until al_uninstall_haptic(3alleg5) is called.

If you need to close and reopen your active display for example, then you should call al_uninstall_haptic(3alleg5) before closing the display, and al_install_haptic(3alleg5) after opening it again.



[Unstable API]: Perhaps could be simplified due to limited support for all the exposed features across all of the platforms. Awaiting feedback from users.
