NAME¶
al_reconfigure_joysticks - Allegro 5 API
SYNOPSIS¶
-
#include <allegro5/allegro.h>
bool al_reconfigure_joysticks(void)
DESCRIPTION¶
Allegro is able to cope with users connecting and disconnected joystick devices
on-the-fly. On existing platforms, the joystick event source will generate an
event of type ALLEGRO_EVENT_JOYSTICK_CONFIGURATION when a device is plugged in
or unplugged. In response, you should call al_reconfigure_joysticks(3alleg5).
Afterwards, the number returned by al_get_num_joysticks(3alleg5) may be
different, and the handles returned by al_get_joystick(3alleg5) may be
different or be ordered differently.
All ALLEGRO_JOYSTICK(3alleg5) handles remain valid, but handles for disconnected
devices become inactive: their states will no longer update, and
al_get_joystick(3alleg5) will not return the handle. Handles for devices which
remain connected will continue to represent the same devices. Previously
inactive handles may become active again, being reused to represent newly
connected devices.
Returns true if the joystick configuration changed, otherwise returns false.
It is possible that on some systems, Allegro won't be able to generate
ALLEGRO_EVENT_JOYSTICK_CONFIGURATION events. If your game has an input
configuration screen or similar, you may wish to call
al_reconfigure_joysticks(3alleg5) when entering that screen.
