Basic Vector Code wanted
Hi.
ER does any one have any basic Vector code in asm which they would like to pass my way please  .On a boot block of a ANC disk, there is a 1k vector intro, but the boot block seems to be compressed so am having trouble trying to dissassemble the boot block. |

You could always, oooh I dunno, decompress it maybe?
 If you're able to understand vector code just from disassembly you're able to run it through a simple decompressor first...Check on Aminet - ISTR there was some simple example vector code on there. |

hey matey I'm having trouble dissassembling the boot block. I can make out some of the code ie where it allocates memory, and then where the program jumps to.
but when I use the 'g' command on the arc to jump to that addy it just does a rainbow effect and i have to reset WinUAE. I'll have a look at aminet again. Also yes I do have that vectors.txt that comes on one of 'the source' compilations but I suck at coding, and just can't code from scratch, unless it's something easy like 'hello world', opening a screen and a window, etc etc. btw: the vector code I want is that 3d gfx stuff, not the hardware vectores ie $6c.w |

How to code vector demos on a MC68000 by Asterix of Movement
It's a tutorial with example sources at the end, should be a good enough starting point. |

Hi I mentioned I had that file that yous mentioned in post #3, as I got it from 'the source' disks, from one of those 'how to code' tutorials.
@AmiGer. Hey matey uploading the disk now, its ANC utilities disk #21, it'll be in the zone. |

Here we go...
the trick is, that this isn't a 1k bootblock, it makes a DoIO-read and reads $1000 bytes from the offset $400 and executes this at the absolute address $24ed8. I post the complete source, IRA config file and binary for you. Have fun. BTW: I found out that you can change some vector parameters by moving the mouse and pressing keys on the numeric keypad... nice ira -binary -a -offset=24ed8 -config vector2 |

Cheers Matey
.I know about moving the mouse gave different affects but did not know about the numeric keypad. Cheers .

For me I didn't boot the disk.
I've seen the keyboard handler in the source... But who reads so much text ???

No offense, but if you get stuck disassembling a 1k bootblock which just does a few simple DoIO commands, you are unlikely to get anywhere with a full on program using the blitter to draw vectors...

.@Mr_Orgasm: not much, Having trouble assembling it in AsmOne1.6, the first error was with the ABSEXECBASE equate. got that fixed, just did a replace to $4, but it should of worked without that. it just seems to be some label problems with assembling it :/. |

redblade, don't hurry, every amiga cracker has once started to use miggy assemblers and disassemblers. I think it's really cool that a 21 old guy is doing this...

, although a hacked version of roxbox would be nice hehe.nah just want to see some of my own vectors rotating in a screen in front of me, that all like a cube/stealth bomber etc. |

managed to find some vector code on google Groups. Good old google groups, lots of interesting posts on there. |
