DARKWAR BOMBER ATARI 4.9.2022

This is a game for ATARI ST mono emulators. It is made with GFA-BASIC
and GBE. It is not tested on a real machine and it is possible, that
it can't be run on it. You can try to run DWBATARI.PRG or DWBATARI.GFA
in a GFA BASIC interpreter. DWBATARI.PRG runs with the emulator hatari
1.8.0 and its built-in EmuTOS-image
(https://hatari.tuxfamily.org/download.html).
GFA BASIC was chosen as programming language to write a program compatible
to EmuTOS. The game can also be run with hataroid and its built-in
EmuTOS-image. hataroid is available for Android devices.
The .LST file was written with the Windows X editor and merged and
compiled with the programs coming with GBE. GBE ran with the operating
system FreeMint 1.19 and the emulator ARAnyM 1.1.0 and the result was
tested with the ATARI emulator hatari 1.8.0.
There is an error occuring with Steem v3.2 (and not with hatari 1.8.0).
The mouseclicks on the upper half of the RESTART and the QUIT button are
not processed.
This game is for two players. The computer calculates nine
screens with 16 cannons of different size. The first player
can choose a screen with the arrow buttons at the borders.
This is done with the mouse. The objects with the white
interior belong to the first player. He clicks on one of
them to select a cannon. Then shot direction and explosion
distance can be entered with the keyboard. The explosion
distance mustn't be on or beyond the borders of the
gamefield. The distance to the border in the direction
entered before is calculated and displayed on the screen.
After the shot is performed, it's the other players' turn.
A shot can cross the borders of a screen but not the borders
of the gamefield. The screens have the dimension of 600X320
pixels. All eight cannons of the other player must be
destroyed to win the game.
