Jumpy!
Version 1.0
(C)opyright 1992 Jon Read
About Jumpy 08/09/92
----------- --------
Jumpy is a platform game for the Psion Series 3 pocket
computer. It was developed over a four month period, in
my spare time, and is the result of many hours of work.
The source code for the game and associated programs
comes to over three thousand lines of code - a lot to
write on a machine that small!
It has been optimised as much as possible, so that the
game actually runs at a pretty good speed. It will of
course slow down if you have lots of other applications
running at the same time, as with any program.
Installation
------------
All program files should be in a directory named "JUMPY".
To create a directory, press PSION-+ whilst on the system
screen. The program needs 4 files in order to run.
These are as follows:
Filename File Size
-------- ---------
INFO.DAT 164 bytes
JUMPY.DAT 884 bytes
JUMPY.OPA 10548 bytes
SCREENS.DAT 9342 bytes
TITLE.DAT 344 bytes
In addition to this, a SCORES.DAT file will be created in
your \OPD directory.
Install the application in the system screen by pressing
PSION-I. When the "Install Application" dialog pops up,
press TAB on the "File: name" item. Go to the root
directory, and into the JUMPY directory. There, select
the file JUMPY.OPA and press enter. This will return you
to the dialog - press enter again. Jumpy should now be
installed, and can be run in the usual manner.
This works if all files are stored on the internal disk.
I haven't been able to test the program running from
another drive as I don't have any RAM or Flash cards!
The Title Screen
----------------
Once the game has been installed and run, you should then
be presented with the title screen bearing the name of
the game and a small scrolling message. Pressing ENTER
will start a game, or a menu can be brought up using the
MENU key.
The menu consists of two sub menus, called GAME and
THINGS. The GAME menu consists of the following options:
Start Game (Psion-S) This will start a new game.
Instructions (Psion-N) Selecting this will bring up a
short list of instructions on
playing the game.
About (Psion-A) Displays a notice giving the
version number and a copyright
message.
Exit (Psion-X) Ends the program.
The THINGS menu contains these items:
Score Table (Psion-T) Displays the high-score table.
Options (Psion-O) Displays a dialog with the
following options:
Info Window (On/Off) Turns the in-game info
window on or off.
Map Window (On/Off) Turns the in-game map
window on or off.
Sound (On/Off) Switches the in-game sound
on or off).
Screen Order (Normal/Random) Selects the order in which
you wish to play the
screens: Normal
(1,2,3,4,etc) or a random
order.
Gameplay
--------
On starting a game, you should see a little round thing
with eyes and feet sitting on a platform in the middle of
the screen. That's Jumpy. You have to guide him round
each screen, picking up bonuses. When all of these have
been collected, a door opens. To finish a screen, enter
this door.
But of course, it's not that simple. There are a few
obstacles here and there, arranged so as to give you as
much hassle as possible. Especially in the later
screens!
Spikes: Contact with spikes hurts, as you will find out.
Jumpy loses one of his three lives if you touch a spike.
Ice: Once you've got used to it, ice isn't that bad.
The only problem is that you can't stand still!
Nasties: They're, umm... nasty, really. Touch one and
you loose one of your lives.
Control of Jumpy may take a little getting used to at
first, but do persevere. To move left, press left. To
stop, either press left again or press right. To move
right, do the same thing only with left and right
swapped. It gets like second nature after a while. To
jump, press UP.
If you want to look downwards, press DOWN. The screen
will change to show you more of the screen below. To
revert back to the original display, press DOWN again.
That's basically it. The first couple of screens are
easy, to help you get the hang of it.
If for any reason you need to switch tasks in the middle
of a game, simply press the appropriate button on the
touch strip. Jumpy will automatically pause, and will
restart when you return to the game.
Game Menu
---------
During the game, you can press MENU to display the in-
game menu. The options are mostly the same as in the
title screen menu, with the exception of "Info..."
(Psion-I, or just I if you want to get there quickly).
This displays a dialog showing information about the
current screen - Your score, the percentage of the screen
completed, the number of lives you have left, the number
of bonuses left to collect, and the number of the current
screen.
System Requirements
-------------------
Jumpy requires at least 63k of free memory to run. This
is a result of the way I handle the graphics - they're
fast, but they take a lot of memory.
In future releases I intend to tackle this problem by
cutting down memory requirements in as many places as
possible, as I realise that not many users may have this
amount free. Especially for those with 128k machines.
Registration
------------
Jumpy does not *need* to be registered - that is, you may
use it for as long as you wish without having to pay me
anything. I'll be quite happy with that.
However, if you do enjoy playing this game, please do
consider sending a small donation (say, five pounds?) to
the following address. Your support will
