The Dink Network

Here's basically how you would use inside_box(); for your bomb item. If you are really determined to use your method, you could at least have a script attached to the screen or something making Dink say something like "I could use that bomb on that object." or something along those lines. Just try these lines right at the beginning of your use procedure. Just replace the left, right, top, bottom variables with the coordinates you need to use.

//check for correct screen
if (&player_map != 450)
{
//Dink isn't on the correct screen
say("Not here!", 1);
return();
}

//check if dink is in the correct area to place bomb
int &dink_x = sp_x(1, -1);
int &dink_y = sp_y(1, -1);

int &in_box = inside_box(&dink_x,&dink_y, &left_x, &top_y, &right_x, &bottom_y);

if (&in_box != 1)
{
//Dink isn't in the box
say("I am not close enough!", 1);
return();
}
