Hey, guys, please help... I have a bmp of a menu graphic and it's loaded in
a .dat file using the grabber. I didn't post it, it wouldn't help the code.
x1, y1, x2, y2 are the coords for the "New Game" button. When the user
clicks inside x1,y1,x2,y2, the prog should execute newgame(). I can't get
it to work, though.

<begin code>
//Menu.c -- mouse-driven menu functions
#include <stdlib.h>
#include <stdio.h>
#include <allegro.h>
#include "resource.h"


int newgame();
void mice();

int main()
{

 DATAFILE *data;
 allegro_init();
 install_keyboard();
 install_mouse();
 install_timer();
 data=load_datafile("resource.dat");
 set_gfx_mode(GFX_AUTODETECT, 800, 600, 0, 0);
 set_palette(data[MAIN_PAL].dat);
 draw_sprite(screen, data[MENU_BMP].dat, 0, 0);
 mice();
 clear(screen);
 clear_keybuf();
 allegro_exit();
}

void mice()
{
 int pressed=0;
 int mx, my;
 char msg[80];
 do{
 show_mouse(screen);

 sprintf(msg, "mouse_x = %-5d", mouse_x);
 textout(screen, font, msg, 16, 16, 9);
 sprintf(msg, "mouse_y = %-5d", mouse_y);
 textout(screen, font, msg, 16, 32, 9);

 for (mx==x1; mx<x2; mx++)
 {
  for (my==y1; my<y2; my++)
  {
   if ((mouse_x==mx) && (mouse_y==my) )&& (mouse_b & 1))
   {
    newgame();
  }
  }
 }

  vsync();
 }while (!keypressed());
 show_mouse(NULL);

}

int newgame()
{
 clear(screen);
 exit(1);
}

<end code>

Please help. maxiv AT sprint DOT ca
