More handy code (elevator)

[Sam Hulick]

Just in case anyone is interested, here's a fully functional elevator.
It's one lacking point is that when you press a button to go to another
floor, it goes there immediately and the doors open (ok, so I got a
little lazy), whereas if it's on, say, floor four when you summon it, it
takes X turns to come down to you. Heres the code.
Check out the !comments! throughout the code.

! These are just rooms in my game. hotel_elev is the lobby level, and
! the other floors are 1-4. elev_doors.number keeps track of where the

nicely carpeted, just like the rest of the building. \

buttons. You can exit to the west.",

w_to elev_doors
has light lit;

Object elev_panel "control panel" in_elev
with name "panel" "control",

has static transparent;

Class elev_button

Push: if (elev_doors.number ~= self.number)

if (elev_doors has open)
{

give elev_doors ~open;

}

give elev_doors open;
StartTimer(elev_doors, 1);
"You feel the elevator move momentarily, then stop. \
The door opens.";
}
if (elev_doors hasnt open)
{
give elev_doors open;
StartTimer(elev_doors, 1);
"The door opens as you press the button.";
}
];

Nearby lbutton "lobby button"
class elev_button
with name "button" "L" "lobby",
number -1;

Nearby onebutt "first button"
class elev_button
with name "button" "one" "first",
number 1;

Nearby twobutt "second button"
class elev_button
with name "button" "two" "second",
number 2;

Nearby threebutt "third button"
class elev_button
with name "button" "three" "third",
number 3;

Nearby fourbutt "fourth button"
class elev_button
with name "button" "four" "fourth",
number 4;

---cut here---

So, the floor numbers are in the 'number' property on the buttons. When
you press a button, the elevator moves to the button.number.

myloc() is just a routine I made because I got sick of thedark
bullshit. It's quite simple:

[ myloc;
if (location == thedark) return real_location;
return location;
];

Enjoy
