Hi Martin, This is with just #10 implemented, showing a score when you hit a asteroid. This is just a quick test, 10 points per hit. Not even sure if that is actually so. rocks6.zip Volhout PicomiteVGA PETSCII ROBOTS |

It's looking good. I can't find playmod sample in the manual only playmod file. RISsound is with rocks6 but I missed the playmod sample files |

Page 90 :  In this game a MOD file is used which does not contain any music data, it only serves as a container for the soundFX. The advantage is that these do not have to be reloaded every time, as with Play Wav, and you can play up to 4 channels simultaneously. So a sound does not interrupt the sound that is currently being played if it uses a different channel Edited 2024-07-27 05:25 by Martin H. 'no comment |

Hi All; The game plays well but I had to rem out all the play modfile lines. Runing PicoMiteVGA 5.09.00RC5. The first time I ran the game it received an error on line 69. [69] Play modfile "RISsound.mod" Error : Mod playback not enabled I am using the VGA board from Land-boards.com PIPicoMite03. Does this require a special OPTION setup or hardware? The audio is on gp6,gp7 and playing a tone works. What am I missing? Hans... |

Thanks for that phil99 The only reference to this is in the option definations. In the next manual I would suggest putting a small one or 2 liner about this before using the play modfile command. Again thanks, Hans... |

Added control from the NES controller to the game, and the game runs much faster on it. (Your NES controller ports can be configured with constants in the program) Replaced the graphics and the game suddenly acquired a modern meaning, it is no longer rocks in space, but tanks on the battlefield and you can destroy it and ram it with a drone! ;) Would it be necessary to think through the design of such a game to the end in detail? 2024-07-28_Rocks.zip |

Hi Javavi I'll try your version later, when I have my NES controller. Looks promising... Meanwhile I have not made much progress. I am fighting something I don't understand yet. The loop time is depending on then number of rocks. So when you shoot the big ones, you get many more smaller ones. But these smaller ones are exponentially more difficult to hit. Not only because they are smaller, but it feels also as if the shots are further appart on screen (looks like it). I am not sure if my eyes deceive me, but the shots further appart is strange. The LCD screen runs 60Hz (16ms) and thus is far faster than the loop time. Each loop time should be shown. At the fastest (18ms) and slowest (80ms). But why are the bullets further appart ? They move "bspd=4" pixels per loop. So I am puzzled.... Anyway, here you get the version with progressive more difficult levels. My high score is 13860 (so when I implement the correct game mechanisms, I would get a new ship at 10000). rocks7.zip Volhout Edited 2024-07-29 06:39 by Volhout PicomiteVGA PETSCII ROBOTS |

Javavi, Yes! The game works much better with a NES controller (or other changes you made) I will anlyze your version, and combine it with my features. I do think the asteroids looks are refreshing new, bt not close to the original... I may leave them as an option to choose from.... Thank you Volhout P.S. I just found the official game rules/limits/score system and will start to implement that first. The major benefit is that the official game only allows for 26 asteroids simultaneous on screen, of 3 sizes (now 6). That helps. When the screen is cluttered with 50 small asteroids (the current limit), the loop gets slow. 26 asteroids allows for more bullets on screen (the loop delay is partially due to check each bullet against each asteroid for a hit).

Martin, others, For what is implemented, is adapted to the official rules. Max 4 bullets, max 26 rocks, score 20,50,100. Javavi's NES controller changes implemented, but GPx pins for PicoGameVGA board from Mixtel90/thwill. Use controller port A for NES controller. There is a whole list of things to do, from small changes to large: - limit max speed ship - stabilize the loop speed (sometimes too fast now) - create small and large saucer, and make them fire (large at random, small aimed). - Show level - Start and end text I think the saucers are the most essential, I'll work on these first. Javavi, sorry forgot to copy your artwork for the asteroids. I will in next revisions. Volhout rocks8.zip Edited 2024-07-29 21:42 by Volhout PicomiteVGA PETSCII ROBOTS |

Hi Martin, Thanks, will add to the game. Did you (or anyone else) ever play the arcade version ? Stan ? In Wikipedia it says that shots do NOT wrap around the screen edges. That is what I implemented. And they talk about a fix from Atari to stop an exploit, and made Atari update the ROM's. In my detailed game description (not Wikipedia) they say the shots do wrap around the game field edges, and they actually promote using that feature to get high scores, into the millions. That may be the "exploit" that Atari fixed by sending new ROM's. So I am not sure what to implement .... Volhout Edited 2024-07-29 23:32 by Volhout PicomiteVGA PETSCII ROBOTS |

Well I played it those days and the Emulated Mame Version. As far as I remember, the shots wraped auround the edges. You can try it here online Looks like they used the original roms 'no comment |

The missiles did wrap around. Position your ship at the bottom/right and when only a few rocks remaining shoot the saucer using the wrap around.. lots of points and bonus ships :) There was another x/y vector graphics game called "Tempest" only it was colour. |

| Volhout Guru Joined: 05/03/2018 Location: NetherlandsPosts: 4223 |
Thank you all for your help. I will implement shots wrap around in the next revision of the game. This revision does not have them yet. But it will change the game significantly. Now you fire a salvo, but when bullets/missiles travel long time (wrap around) you must focus more on single shots. On the other hand, many will hit something in the end.... This version has the basics of UFO's. Not tuned (so they may be too easy) and the small UFO does not aim its fire yet. the speed at which they move may also be too slow (easy prey). But it is becoming more and more a game..... fun to play... rocks9.zip Volhout P.S. this version is so easy to play you can easy get over 10000 points in one level. Just shoot small saucers. Leave the 4 big rocks as they are. They are almost harmless... Edited 2024-07-30 05:30 by Volhout PicomiteVGA PETSCII ROBOTS |

The saucers shot missiles :( the ship missiles went about half the vertical screen height. it had the same bass as space invaders that got faster as more rocks shot. the original game play was the ship moved and rotated fast. does using a usb keyboard slow the game. would a i2c port expander be faster? |

@Volhout Could you please add a question (or some fancy coding) to bypass the Nes controller for KB use only, if no controller. When I ran rocks9, for the 1st time, it was very challenging to control the rocket as it increased to warp speed on it's own and shoot by itself.  Thanks so much for the game it is lots of fun! Hans ... PS: I coded my own bypass to the controller, but I am sure your coding would be more elegant. |
