My old "scroll" game - BASIC program listing

Post by Brana » Tue Dec 02, 2008 5:23 pm

Hello everybody, last weekend I dug up
couple of Oric Tapes (real cassettes!)
with MY OWN programs on it!

Incredeably - they STILL "Cload"!

Among the contest on these tapes
I found my very-first "scroll game"
that I wrote long time ago, using
Oric Lores0 mode.

The game is rather simple: goal is
to fly trough the field of objects and
to AVOID CRASHING in to ANY (yellow)
object(s)! Note: You use "arrow" keys
for your movement.

Also, the game is quite short
(in terms of Basic program), and
it is rather cute (if I may say so,
being it's programmer - haha!), so
I wish to share it with you all!

Below is the Basic program listing:

You can use TXT2BAS.EXE utility to
convert this listing to a TAP file,

Or - You can use your keyboard to
"type it in oldfashionably" as I did on

And at the end - the game is rather
slow (5Mhz Euphoric Emulator is highly
recommended!) Sorry for this, but
actual scrolling in this game is
realized trough the "arrow-fields"
and Oric can be very SLOW when it
comes to manipulate "data" stored in
the "arrow fields" (those created with
the command "DIM").

;Program listing:
