To start drawing the track, you draw 128 horizontal lines that go into the distance, the spacing getting less and less as you draw higher up the screen, and the width getting less and less too. Just a really basic 3D projection in 2D. Code:
--- ----- --------- --------------- Code:
--- ----- ------- --------- ----------- ------------- --------------- Then, for corners, you'd have a value of '4' for a corner. This means you shift each line across exponentially by four from the front to the back. (4, 8, 16, 32, 64, 128, 256...). Because you've projected the lines in 3D (on a 2D surface) the track appears to curve (rather than take a straight line off to one side). To do hills, it's the same principal. It's just a curve that operates on the y-axis instead of the x-axis (and uses smaller adjustments so it doesn't end up looking like a cliff ). That's simplified quite a bit in that there's a lot more going on to achieve the Lotus look over, say, the Pole Position look, but that's the basics. Once the game is further through and I have time I'll take some screenshots with certain stuff disabled and some debug info which should de-mystify the process a bit. |

This look really great P-J, good luck with it
Loving the explanations too.. I'd loove this on iPad, but I guess that will always be out of the question. (silly me, just re-read your original post, IOS planned ... nice!) Last edited by Christian; 31 January 2012 at 11:00. Reason: oops |

Yeah man, it's making good progress and it should really be a breeze to get it on to iPad and iPhone.
That said, I've not even tried an iPhone build yet, so while I'm waiting for the graphics I may well fire up the Mac and give it a go. |

Well, I'd buy it. Especially since there doesn't seem to be an Amiga emulator available (I realise you probably won't be able to charge, etc) but still...

If I had an iOS device it'd be a must buy for me too.
If I got a mobile OS it would be Android. So be cool to see a version of that out too. |

Yeah Dreedo, know what you mean. Android would be really nice. I stuck Day of the Tentacle on my Mrs' droid phone last night, she loves it!
Bit OT but I'm not an Apple fan, but I don't have a smart-phone, no laptop, just a very powerful PC. Was after a "comfy" system to use and tbh, the iPad did it for me over the rivals. Also into creating music, etc and there is loads of stuff for it. Jailbroken of course Mario-Kart and Outrun arcade with a proper controller ... in bed ... oh yes lol No Amiga stuff (apart from some remakes, including the very excellent Battle Squadron, and others) makes me sad. Lotus 2 remake would go some way to fixing that for me. One of my faves. |

this would be a beauty on the Ipad with an icade controller, with the most biggest Bonus of Multi-online play, but I fear now, since Gremlin graphics have returned from the dead and are create stuff stuff for IOS, they'd kick up a storm over licencing etc.. , if they was ever to goto the Appstore, wondering if there is a another way to play online gaming, like this one, without using Openfeint?

Yeah, I'm loving using the Wii controller along with the Classic Controller Pro, although I have a horrible feeling Apple don't allow that for official stuff
Stupid really. Something to do with low-level Bluetooth stuff I think ... who knows.. Edit: would be nice if this became THE official Lotus release with Gremlin involved, etc. Like I said, I'd pay |

Thanks for all the comments dude.
Regarding the whole 'charging for it' and 'official Gremlin' thing, I'd certainly never try and charge for it for two reasons-- The original develoepr helped me a lot, and because it's not my IP Not sure how to approach putting in in the app store-- I guess even if it was free the original developers could take exception to it and I might get a nasty e-mail. Perhaps a non-Lotus rebrand might be necessary. Or I could just take my chances. |

Be careful what you wish for, apple themselves have a really strict line of conduct, and have a 3 week queuing system for new apps to be released on the app store, I've read a good few stories where apple don't allow games or apps on there store without giving any reason what so ever, and a simple complain from another company claiming. Copyright infringement and it's pulled, but yes this would be a great edition to the app store not doubt about it, and who gladly pay for it on the app stored, purely for the online play along.

I think Apple would let it pass, I know there are a few games that push the boundaries available for it.
Android will certainly allow it, theres several Minecraft clones on Android, some with names almost exactly the same, and they don't get pulled. Of course if the original developers complained to either, I'm pretty sure they'd pull your app from the market. |

Hey.
Great work on this, Lotus was 1 of my favourite racinggames on the Amiga, next to Jaguar XJ220. I just had this idea, how about some rally levels now and then with lots of dirt, mud and gravel Did lotus make Rallycars btw in the past? anyone? |

Hmm nice, could be used for some kind of "Lotus Rally Bonus Level" or something.

That is a cool explanation that makes me feel a little silly for not figuring that out partially myself.

That's not to say it's technically complicated, because it's clearly not! It's just been a long road to get it to this stage. Factoring in of course that the chap made this game over 20 years ago now, most of the stuff was from memory. And memory doesn't really last that long Now all I have to do is get it finished, which I'm determined to do! |

Hi! This thread is pure awesomeness. Thanks for the explanations and videos.
I'm looking forward to implement the track drawing algorithmn in JavaScript/HTML5Canvas for educational purposes. Just a very simple demonstration without any textures. |

hi P-J,
a user has written about your project on a german retro games site, and i just read, what you are about to develop here. man, as a thirty something, who played the lotus games on the amige 500 when they came out, i can tell you, your idea rocks big time. my suggestion is to make a game as near to the originals as possible. of course some of the ideas mentioned here are very cool, but they should be available as an option, not as a must. please make this game run on android and keep in mind, that a lot of mobile phones have smaller resolutions. mine has 480 x 320 for example. and dont forget about a touch screen steering possibility, as i cant stand tiliting the phone around all the time. if one day i will be able to play lotus on my mobile phone thanks to you, you will be my personal hero, and i will be very thankfull. can you tell, when the game will be done? btw: i would be willing to pay for that game, if neccessary, but i will gladely donate anyway, as i read you consider not to take money for it, you noble guy greetings from berlin, mate!
