noob requires help to start coding
ok here goes, i would like to code something for the C64, don't have a clue where to start, i cnow a little C, a little more BASIC and havent even looked at ASM, so what im asking is -

spinal : VICE allows to remap keyboard , actually linux version of vice is configured as PC layout by default - not c64 alike (so pressing shift+2 gives @ instead of " ) and this should also be confgiurable under windows. |

can i assume that BASIC would be too slow for a side-scrolling platform game? (cos thats what i would like to eventually do) |

no, as i said: on c64 you have to use assembler for EVERYTHING except a few tools which spend 99% of their time waiting on user input and printing text. |

are you saying BASIC is NOT too slow, or that it IS? |

BASIC _is_ too slow. You need to code in assembly to do demo stuff. |

spinal: to give you an idea: to calculate a 256 byte long sinus table takes about 1 minute in basic. |

morning :)
I think all basic indeed good for is testing stuff.
Simple stuff. Like making sprites or something. If you already did it in basic, it well get even simpler in asm. The main prob about basic and speed is, that its 'unpredictable' - there are many rather odd ways to speed up basic. Non of them is nice ;)
In your case, I'd take a nice asm-tutorial thats not all too technical and start right away. Maybe with a monitor-prg frist but you will soon want an assembler I guess. First programs are just as easy as in basic and acutaully they make more sense.
I think this one is nice for very first steps:

Have fun & code well,

enthusi: I wouldn't recommend Richard's tutorial, there's so much stuff in it that just doesn't make sense.
Check out Programmer's Reference Guide or C=Hacking instead. |

Stop whining and start coding for christ sake!
1. IO-map: http://www.hut.fi/Misc/cbm/docs/c64-io.html
2. OP-Codes: http://www.oxyron.de/html/opcodes02.html
3. Assembler: http://www.cc65.org/
4. Emulator: http://www.viceteam.org/
5. People to ask: Channel #c-64 @ IRCNet
6. Brain
I used then above recipe and it worked out pretty well...

also worth to check out is this one. The Best C64 Ml tutorial collection
if you're not able to do a demo after reading that one, you prolly not should do c64 stuff at all.. |
