Sub Attack Version 1.11 © 1991, 1993 by Perry Rosenboom July, 1993 Box 333 Wantirna South Victoria 3152 Australia Introduction Sub Attack is based on the old "shoot the ships" arcade game. The idea is that you have to launch your torpedo at the correct time so that the torpedo meets the ship as they both travel across the screen. The concept is simple (I'm sure that you've seen it before...). This documentation file is used both for the registered and shareware versions of Sub Attack. Differences are detailed (where appropriate). The controls Sub Attack is controlled using the mouse. The left button fires the torpedo. The catch here is that you only have one torpedo on the screen at any one time. The right mouse button brings up another screen which explains the scoring and has buttons for selecting the "about", "credits", "high score" and "help" screens. Scoring Points are awarded for destroying ships (what else?). There are four types of ship, each travelling at a different speed. The faster the ship, the more points you get. After you destroy 20 ships, you move to the next level. Ships are launched more frequently on progressive levels. If you miss 20 ships, the game ends. Version 1.11 Version 1.11 has been recompiled with AMOS Compiler 1.35 to support all versions of WorkBench, including AGA machines. See the "Supported Systems" section for more information. Version 1.10 Version 1.10 has some enhancements and bug fixes included. The main difference is support for NTSC machines for my US friends (Hi folks, I told you it would happen eventually!). There are a few other small changes (bug fixes? who said bug fixes?), and I'll let you find them for yourself. The playing screens used on both NTSC and PAL systems are identical, with the exception that the NTSC machines will have less sky (it's only there for decoration anyway). The menu screen has changed slightly, as I've moved the buttons up so they can be seen on an NTSC screen. I hope you like version 1.10!!!! Systems Supported This game was developed and compiled using AMOS and AMOS Compiler (Copyright Euorpress) version 1.35, which supports Workbench 1.3, 2, and 3. This means that this game should work on A500, A600, A1200, A2000, A3000 and A4000 machines. I do my best to support machines available at the time of writing the game, however I obviously cannot test every aspect of the game on every machine. If for some reason the game doesn't work, check the 'Troubles?' section below, and send me a polite letter, and I'll see if I can help. Obviously, registered users get priority. Abusive letters (such as one I received from England) will get no response. People who write shareware and public domain software do so because they enjoy it - abuse will only result in LESS software being developed for public release. We can't hope to make our shareware profitable, but we do hope that we are respected for our efforts. End of sermon. The Shareware Stuff The registered version of Sub Attack differs from the Shareware version in a number of ways: - The registered version allows you to play another game without clicking on the icon again (a requestor comes up whenever a game finishes). - Registered versions are registered to specific people, and these people have support for the software. In other words, I'll try and fix and bugs that are found. I'll also send registered users Version 2 (when I complete it). Version 1.10 (and NTSC support) comes as a direct result of user feedback. If you have any other ideas, then let me know!!!! - The shareware version is not supported. Bug fixes and enhancements will be supplied to registered users only. - The registered version doesn't have the annoying shareware message which pops up on a random basis. Registration Details To make registration easier, you can send money in your own local currency (cash please!). The amounts are listed in the table below. To register for Sub Attack, please send the appropriate amount to: Perry Rosenboom Box 333 Wantirna South Victoria, 3152 Australia Country Registration ------- ------------ Australia $10.00 New Zealand $15.00 USA $10.00 England £5.00 Germany Dm 10,00 Canada $10.00 Please send cash only as our banks can act like robbers and charge us $6.00 to change a foreign cheque. Cheques in Aus$ drawn on and Australian Bank are also acceptable. Prices are based mainly on the exchange rate, although it's a little difficult because our dollar goes up and down like a yo-yo! If your country is not listed here and you would like to register, then please contact me! Troubles? Most problems seem to be caused by low memory. If you notice that the screen is not refreshing correctly, or that the menu bar doesn't disappear, you've got memory problems. Most games these days are designed to work in 1Mb minimum, and this game is no different. If you have 1Mb or more and the game is still presenting problems (especially after you have been playing the same game for some time), then the memory may be fragmented. Try closing down some other programs, or closing down the game and restarting it. The other problem which I have heard of can occur on Workbench 2 and Workbench 3 systems. On these systems, it is possble to change the default font to something other than 'Topaz 8'. This game was written using the default Topaz 8 font, so if you notice that text does not fit properly in boxes or on the screen, you may need to alter your Workbench setting and restore 'Topaz 8' as the default font. Thanks and previous registrations In version 1.00 I said that I'd thank people who wrote to me or registered, so here it is! Thanks to Bill Spring (Frankfurt, Germany) who sent me a letter before I even knew that Fred Fish had released the original version of SubAttack! on disk 554. Thanks also to Stan Kendall (Barrington IL, USA). Stan very kindly took the trouble to send me some photos of my game running on an NTSC machine. Here it is Stan!!!! Thanks to the following people who registered for Version 1.0, and who will have received registered versions of Sub Attack 1.10 before the shareware version is released (yes - you do have some privileges when you register!) Bill Spring - Frankfurt, Germany Stan Kendall - Barrington, IL, USA Mauricio Telleria - Edmonton, Canada The Humphries Family - Grand Rapids, Michigan, USA A big "thank you" to Fred Fish! Distribution of Sub Attack and other boring terms and conditions The SHAREWARE Version of Sub Attack may be freely distributed, providing this documentation file accompanies the game. Neither the Game or this documentation may be altered in any way without the Author's written permission. No more than a reasonable fee for copying and distribution should be charged for the Shareware Version of Sub Attack. Registered Versions of Sub Attack are provided only to the registered user and are not to be copied or distributed under any circumstances, unless prior permission has been provided in writing by the Author (after all, a great deal of time has gone into writing this game). Both the title screen and the "About" screen clearly display whether the version of the game you are playing is shareware or registered. High Scores At the time of writing this documentation, my high score was 10340 (Level 12). Let me know if you can do better, and I'll put a high score list in the next version of the documentation. End bit Well, that's it. There is not much more I can say about "Sub Attack", except that I hope you enjoy it. "Sub Attack" was proudly written in AMOS, © Europress and compiled using the AMOS compiler (Thanks Francois!). Special thanks to Andy K and all those who register (I'll name you in the next release!). Sub Attack is © 1991, 1992 by Perry Rosenboom. The ships used in Sub Attack are based on the sprites supplied with AMOS. --------
