 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

First make it work, then make it effizient by following the YouTube Tutorial step by step, i translated the C /openGL Code to MM Basic and tested it on a 378000 kHz Pico Vga. Speed on the Pico is ok but I am sure that there is much to optimise also tested on MMBasic4W  as in the Video, there is no collition detection by now.

Very nice Martin, a bit slow on the poor old PicoMite but nothing a bout of optimisation, or failing that, a CSUB wouldn't fix I'm sure. I have once again taken the liberty to use your code to continue ironing out some issues with my controller library: CMM2 version with support for Wii Nunchuk, Classic, and on the DX version Atari joystick and NES gamepad; note that the latter requires an adapter to cross-over the power pin: raycast-cmm2.zip PicoMiteVGA version with support for Atari joystick and NES gamepad using the PicoGAME Port A pins: raycast-pmvga.zip Best wishes, Tom Edited 2022-11-23 23:37 by thwill Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Hi Tom, sadly, I haven't found any instructions on the web yet how to compile CSubs for the Pico (Environment, compiler etc). But maybe, I Find a faster Algorhitm to do the casts in Basic. On the Website, where the BubbleDemo came from, is a Algorhytm with a different approach. For Now, you'll get it a little faster by lowering the resolution change in the drawRays3D sub than it does less Scans per Frame For r=0 To 119 to For r=0 To 63 and the Part Box xstp,(hv>>1)-LineO,1+hh/60,Lineh,,wcl,wcl Inc xstp,hh/60 to Box xstp,(hv>>1)-LineO,1+hh/32,Lineh,,wcl,wcl Inc xstp,hh/32 PS: Your Version works well, as long as I use Port A for Atari or NES Controller Edited 2022-11-24 00:41 by Martin H.

Hi Martin, you didn't ask but how about this: For infos about CSUBs on PicoMite: https://www.thebackshed.com/forum/ViewTopic.php?TID=14126 I would like to compile your C-Code if you want. Regards Michael |

Yes, you do somewhat have to piece it together from bits and pieces on TBS. I haven't done it for the PicoMite yet, but did a couple of years ago for the CMM2. I would say that figuring it out and documenting it clearly was on my TODO list, but that would imply there was an actual list as opposed to a flaming trash heap of despair  .As expected, I only included the code necessary to support Port A (and I2C Channel 3 on the CMM2).

the irony of the story is, I translated the Source from C /openGL to MM.Basic to see, if/how it could be done. Going back to C now would be a little like cheating.  I now understand the Ray Cast functions. I had already managed to do that on the Atari ages ago. But even if I get the Ray casting with a more efficient algorythms in Basic fast enough, I dont think it would work If I try to implement texture mapping.  'no comment |

Martin, thanks for your work here, very interesting. Some suggestions: 1. Add to buttons() sub: case Chr$(27) '<ESC> If Mm.Device$ = "PicoMiteVGA" Then FRAMEBUFFER CLOSE: CLS: END Else ??????? Endif 2. Convert dist() function to a cSub as this is called many times within the 120 loop in the drawRays3D() sub. I have tried but failed to generate the code for the PicoMite. Maybe someone else will have better luck. led Miss you George |

Hi Led, in my working Version I didn't use the Distance Function anymore, cause every Function call is timeconsuming .. So i do the pythagoras calculation within the Program, two times Also, to speed things up I try to use "IF THEN" in the Loop only if it is really necessary. That's why some adventurous lines come out like : Inc ra,P2I*(Ra<0)-P2I*(ra>P2I) to keep it in the Range of 2 PiAnother way to optimize would be to rewrite the Algorythm to use degrees instead of radius, so I can convert the "floating Point Calculations" to Integers. the best CSub would have to contain the whole Raycast Function like Cast PX,PY,PA,Casts that returnes the "casts" number of distances in an Array which can be read in the Draw_Wall Sub. :-)As you can see, there is still a lot to optimize. I have to go to the office now, but I'll think of something. Cheers, Mart!n Edited 2022-11-24 16:25 by Martin H. 'no comment |

Great. I'll try and find time to give it a spin over the weekend, but got a lot of family stuff going on. The version you've posted has the PicoMite controller/keyboard code included in it, not the CMM2/MMB4W controller/keyboard code. Should work on the PicoMiteVGA if you've got the firmware with the PS/2 support, and if you haven't you should have been getting an error from the call to ON PS2 ... ah, I see you have commented out the line to ON PS2 ??? you'll need that uncommented ;-) Best wishes, Tom Edited 2022-11-26 01:49 by thwill Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Right, you need a different keyboard driver if you are using a serial terminal, the "single source of truth" gets quite convoluted in the area of the keyboard: ' When a key is down the corresponding byte of this 256-byte map is set, ' when the key is up then it is unset.

Of course developers can do what they like with my library the main thing is to settle on the API for the driver SUBs which I think I've done.

Hello with my PicoVGA i got a [18] FrameBuffer Create Error : Unknown Command with the first listing. The PicoMiteVGA User Manual MMBasic Ver 5.07.04 shows no FrameBuffer commands too? What's wrong with my PicoVGA? |

You need a later version https://geoffg.net/Downloads/picomite/PicoMite_Beta.zip |

Thanks for the link, is there a description of the new commands(sprite, framebuffer, DRAW3D) for the Picomite VGA? This is quite limited in its capabilities. |
