mouse_on_screen(3) Allegro manual mouse_on_screen(3)NAMEmouse_on_screen - Tells you whether the mouse pointer is currently on
screen. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
int mouse_on_screen();
DESCRIPTION
This function can be useful to prevent having two mouse pointers on the
screen at the same time when running your program in windowed mode and
drawing the mouse pointer yourself. Other possible uses include the
ability to pause your game when the mouse goes off of the window, or
only scrolling the view when the pointer is near the edge of the win‐
dow, but not while off of the window.
Example :
if (mouse_on_screen()) {draw_sprite(buffer , mouse_sprite , mouse_x , mouse_y);}
RETURN VALUE
Returns 0 if the mouse pointer is off of the screen, or non-zero other‐
wise.
