want to code
OK dudes... I need to start coding. I am in the need to get up and running... I am a fool and an idiot but I know a lot about the c64 and I know how to but not in code. I need someone who can guide me to start to be a coder, that said it is not like I want to be feed with links... I want to start coding with you as a guide and my mentor!
My dream: is there someone who can put aside one hour a day or second day with me and that know how to make me understand the basics so that I can expand on my own? I know nothing in commands and such as of start we can assume.
I know it might sound stupid but are there anyone out there who could do this? with me?
I can pay back with logos, graphics, part ideas and such...

Still one of the most complete tutorials about coding: http://codebase64.org/doku.php?id=base:demo_coding_introduction
When I started coding, it was very important to understand and get a feel of the hardware itself, e.g. getting the VIC registers right and the register thingie (A, X and Y). The commands itself are very basic, like Mixer explained (store values at specific times in a certain register...) |

Quoting FungusI suggest getting Jim Butterfield's book if you are a complete beginner.
Seconded, Butterfields book is the best to learn from, and once you have the basics down you should read Puterman's articles on demo coding. |

thanx for answering. I have started a bit here. I know how to set colors of screen and border, I know how to pint at a mem location and also to display something from there in a sprite or as chars on screen. I know some basics... I do not know but I start to understand some. I think it is so hard to get the concept of a loop and then something else should happen but still continuing in the loop and all but I think with some practice it will come to me.
Made a logo shower today.

I will check out different stuff more. Thanx to all that did send me messages and also answered here and my dudes in offence and so on.
I will code a part on the c64! |

Remember that everyone starts from the beginning. Not a case of someone waking up one day then coding a trackloader immediately etc. Carry on persevering and dont give up |

I'm also in the process of learning how to code and I find the book "The Programmers Reference Guide" very helpful. I'd say it's almost a must-have along with the original c64 Users Guide.
Nice logo showers you coded. However you are assuming the charcolour is light blue. That is not always the case, so you need to change all the characters on the screen to be light blue, colour #$0e, easily done with a small loop:
lda #$0e
ldx #$00
loop sta $d800,x
sta $d900,x
sta $da00,x
sta $dae8,x
inx
bne loop

Cruzer will of course tell you that you need to unroll your loop to optimize your code :-)
lda #$0e
sta $d800
sta $d801
sta $d802
...
sta $dbe7
... Or more likely even: code an algorithm that generates the unrolled code, optimizing both speed and file size. :-) |
