codebase.c64.org
Hello!
Just wanted to tell you all that the C64 codebase wiki now got a proper URL and can be accessed through:
http://codebase.c64.org/
Enjoy! Greetings to Slaygon for supplying the URL. Now you don't have to remember that old weird URL. ;)
Keep on adding your stuff!

Great work guys!
btw how about advertising the site? lemon64 / c64.sk / pouet / c64.org for example. atleast the bigger c64 crossroads of the web should have a link to it. |

@Oswald: Yes.. that will be done. Concerning c64.sk there was also some idea to make a rss-feed visible there. The wiki has some support for that.
@Icon: No problemz. Btw, right now the codebase.c64.org URL seems to link to the site by hiding the old URL within a frame, which means the user won't see URLs to different pages in the browser. Would it be easy to make a more proper "link" from the URL to your server so that the ~cswiki folder would transparently appear to be the root from the viewpoint of the site? |

yes, i would also strongly recommend to have (manually verified) accounts, it would be sad to see that site go down in wiki-vandalism |

as Frantic mentioned. I would like to make sort of "latest additions to codebase" column. Similar to Latest CSDB posts.. etc. Also I will add button to affiliates. This is a very good project. I like the idea.
As for manual account checking. I'm all for. Also zero tolerance to idiotic behaviour would save some time for serous stuff. |

Sure, but that kind of trouble just isn't there yet. I have backups of the site, so.. no worries. The day it happens, well, let's take those troubles at that point in time. |

gpz: I see a huge drawback in making it hard for people to edit the wiki. What exactly is this big danger you see? If someone fucks the wiki, then there is the backups (which are made regularly)... ...including the fact that there is logs and all old revisions of pages are stored and so on.
The day someone start to fuck it up, then there is always the option to make access rights more restricted. Until that day, why make it even one inch less easy to access the functions on the site than necessary? |

the point is that it WILL be fucked up. as soon as its advertised a bit and the link is known to google the spambots will come, wait and see :) |

I agree that it will probably happen... that's not the point at all. Don't worry, as I said.. the day the site get fucked up, it will be restored in a flash and access rights restricted... |

I agree to groepaz, but you can query a (graphical) code when saving a page edit, which is what i just implemented for my own wiki. |

kerm1t.. yeah.. thought about that. Will only stop the spam scripts of course, but still.. kinda middle solution.. at least for a while, or something.
Anyway.. Ppl.. Now go back discussing C64 related matters. All these discussions about websites and so on rather than their contents make me a little sick. :) (I am probably guilty to this aswell..) |

I second that. It sounds like a great idea.
I originally learned some of the demo programming from The Phantom's assembly coding tutorials disk mag (Coders World), as well as from various resources on the Internet like C64.cz utilities section :)
Maybe the codes from the diskmags, with tutorials, etc should be added to the C64 Codebase Wiki. I am sure it would be helpful to new people/programmers to the scene. ;) |

Yes.. The only "problem" is that I dunno exactly how to handle such material in the best way possible. In one sense I think they should be read only, since it would be a distortion of the original material to have them wiki-editable...
Thoughts? |

Some of the articles also contain error's and bugs, it would be nice to fix them.
also, head over to www.ffd2.com/fridge and grab all the code there.

Frantic, I think to create a little article writer community it is a must to only allow registered users to edit. but this is only half of my idea, the other half is to make a little forum on the mainpage for messages like "I have added/corrected XYZ" "nice job dude! keep it coming" etc... so this way we would be able to see who made what and also encourage ourselves to add more. :) its pretty soulless to see that the article was edited by 212.63.45.125. :-|
so.. jackasser keep that timing stuff going, dont give up so soon :) |

@Frantic: i don't know much about wikis but, what do you think about moderation of the wiki (from a correction perspective)? I think if you do not want to add writer accounts, than you have a plan on a core team of moderators that routinely checks the content for correctness. Someone can go ahead and put wrong info there and then someoneelse would need to fix it. I don't fully understand which approach is cheaper nad forms a higher quality of content. If you handout trusted writer accounts to respected coders that know their stuff, you could in a way guarantee the correctness right? I might be wroong though just brainstorming :) |

I think this wiki desperately needs a seperate forum and a bunch of "Discuss This Source in Forum"-like buttons attached to all the articles and sources. So that all discussions related to one particular source would remain in one forum thread and article related discussions would remain in one forum thread related to that particular article. |

I think at first it should be open to grow to some "critical mass" until people find it valueable enough to go through the hazzle and open accounts. |

a discussion plugin for dkuwiki is avaialbe so commenting-discussing each page is possible .
Frantic , did you install that plugin?

A reply to some things touched on here..
As the poll on the mainpage shows, most people would like registration to become required for editing of contents. I respect the opinion of such a clear majority, so, that will happen. Only problem is that the server happened to be on a network that do not allow mail ports to be used freely, and the wiki uses mails in order to verify new accounts. A workaround is being worked on as we speak and if it fucks up for real, one can always change to some other server. Apart from this mail issue I am very satisfied with the current one though, so I won't just move to some other server without good reasons. Anyway, required registration will at least make sure you can see clearly who edited what, rather than the IP numbers you see right now. (Btw, if anyone really wants to, I can add them as users manually right now. Did that for Raf for example. Just send me a message with your desired username/password and your email, and I will take care of it.)
When it comes to the quality of the contents.. that is everyones responsibility. Note that you can write FIXME anywhere, and a yellow fixme button will appear. Check for example the one Raf added here:
http://wikholm.dyndns.org/~cswiki/doku.php?id=links:start#simul..
That is a good feature to use in case you cannot fix something yourself, but knows that it requires fixing in some way. (Although I think Raf used this feature slightly wrong in this case, since it does not relate to a problem with the contents of the wiki, but rather a tool completely external to the wiki. I'll probably modify this soon, but in the meantime I'll let it remain just so you can see just how such a FIXME flag looks.)
A forum.... Perhaps... I think the best way to handle that question will be another poll, which I'll put up when the mail issue is solved. "Do you want this site to have a forum? Yes/No/I CAN'T FUCKING DECIDE!!!" Good? (However, keep in mind that there is little danger involved here; Namely that crucial/good/important info related to a certain source/article then will be spread over the site in the article/source on the one hand and in the forum on the other hand, rather than all kept in a single place.) Anyway, I do see a point with being able to discuss something before changing/adding etc, so why not. But the poll will decide. As Raf says, there is a plugin for this, so there is no technical obstacle. It would obviosly also be a good feature in case someone has a question about some source/article...
Keep the opinions coming!

Eh someone make a tut on how to edit this freakin wiki :D
I post some code here, someone move it over there... I can't be bothered.
-------------------------------------------------------------------------------- ----------------
You should be able to have 1 independant color per sprite, and also an independant image for each
sprite. You could also add fore/background priority buffers and add that register to your plot code.
I chose to go for shortness in this routine rather than pure speed. It can be speeded up about
20% by unrolling all the plotting loops and using self modifed code instead of the second set
of plotting buffers. d010 and d012 storing and comparing could also be precalculated.
Now, the goods.
We are using 32 sprites, so we are going to call this variable (maxspr) from here on.
All of our defined tables will be of length(maxspr). The first table we need, is our linked
list. Our most important table, as we sort this linked list instead of all our tables.
Lets define it.
maxspr = $1f
sort = $02
ldx #$00 ;init x with 00
loop txa ;transfer x to a to create index vals
sta sort,x ;store it in the sort table
inx
cpx maxspr+1 ;have we reached 32 yet?
bne loop
This routine puts numbers $00 to $1f (32) in the linked list table. Now we have our sort table defined.
The sort buffers can be in any memory area. I chose zeropage for speed. Now lets set up some sprites
and colors in our sprite data buffers.
each buffer takes (maxspr) number of bytes.
ypos = $c000 ;sprite y position frame buffer
ybuf = $22 ;sprite y position raster buffer
xpos = $c020 ;sprite x position frame buffer
xbuf = $42 ;sprite x position raster buffer
xmsb = $c040 ;sprite x msb frame buffer
mbuf = $62 ;sprite x msb raster buffer
sprc = $c060 ;sprite color frame buffer
cbuf = $82 ;sprite color raster buffer
sprp = $c080 ;sprite pointer frame buffer
pbuf = $a2 ;sprite pointer raster buffer
jsr movspr ;preset sprite coordinates
jsr anim ;animate sprites
jsr colors ;adjust sprite colors.
Now that we have set up some sprite to show, lets go ahead and precalculate the first frame
to prevent any update bugs, due to excessive sorting of the first frame. This is a special
sorting algorythm, which I discovered on Cadaver's covert bit ops page. It comes from the
Imagine games done for Konami and several others. It's nice too see that good old 64
programmers came up with the idea of a prediction sort that long ago :) The speed of this
sorting technique is unmatched, it uses a prediction, which is really just the previous
frame's sorted index. Y positions generally do no change by a radical amount from frame to
frame. This is ideal for Multiplexer sorting, as it takes less than 2000 cycles to sort 32 sprites.
Otherwise the routine is a simple swap sorter, which is not very complicated at all :)
Here is the routine.
ldx #$00 ;init x index to 00
loop1 ldy sort+1,x ;load y index from linked list plus 1
loop2 lda ypos,y ;load a with y position for that index
ldy sort,x ;load y index from linked list
cmp ypos,y ;compare yposition(index+1,x) to yposition(index,x)
bcc swap ;if yposition(index,x) is less than yposition(index+1,x) then swap the indexes
inx ;if more than, increment index
cpx maxspr+1 ;checked all ypositions?
bne loop1 ;no
beq end ;yes
swap
lda sort+1,x ;swap yposition(index+1,x) with yposition(index,x)
sta sort,x
sty sort+1,x
tay
dex
bpl loop2 ;if not first sprite loop to main
inx ;correct index
beq loop1 ;restart sort from sprite(index+1,x)
end
Quite simple isnt it?
Ok, now lets setup our irq chian, so we can see this bumch of sprites weve just arranged.
jsr setirq ;setup irq.
In runtime code
main lda timer ;wait for signal, that the buffer swap is complete.
sta mloop+1

slep lda ypos,y
ldy sort,x ;this sorter uses the previous frame as a prediction buffer.
cmp ypos,y ;as y position does not change much from frame to frame.
bcc swap ;otherwise, it is a simple swap sort.
inx ;our linked list (sort) is sorted in decending order, according
cpx #maxspr-1 ;to sprite y positions.
bne slop
beq end

lda sort+1,x
sta sort,x

bpl slep

end
ldy sort ;re arrange frame buffers, into the raster buffers.
lda ypos,y ;this is unrolled for speed.
sta ybuf ;this allows us to use only 1 index pointer for our sprite plotter.
lda xpos,y ;it is double buffered, to allow runtime code to calculate the sprite
sta xbuf ;positions.

sta mbuf+1

lda sprp,y
sta pbuf+1
and so on until max sprites.
ldx #$00 ;find # of used sprites (you can remove sprites by
stx sptr ;placing #$ff into the ypos buffer for the corresponding
maxc lda ybuf,x ;sprite. It will not be displayed by the raster routine.
cmp #$ff
beq mxs
inx
cpx maxspr
bne maxc
maxs stx cnt ;max sprites this frame count.
cpx #$07 ;check if were doing more than 8
bcc maxm ;if not, we want the plotter to stop after 1 irq.
ldx #$07

sta $d00f

sta $fffe ;this one, to turn the sprites back on ;)
lda #>irq1 ;i.e. lda #$ff sta $d015
sta $ffff
lda #$28
sta $d012
jmp eirq
Since the buffers have been reordered into proper decending order, we can use unrolled loops for the sprite
plotting. Each plot irq , is for each sprite in the order, 1,2,3,4,5,6,7,8 respectively.
We have a counter (mnt) for 0-7 sprites, as we want to go ahead an plot the first 8 sprites all at
once. We also have another counter (cnt) for the maximum number of sprites to display this frame.
If (mnt) has not been reached yet, each irq branches to the next, to plot the first 8 sprites.
After that, cnt is checked to see if were done plotting sprites. If not, each irq checks the postion of the
sprite from the previous frame, to see if its time to be done yet, if it is, it branches to the next irq.
If it is not time yet, it calculates the next raster irq position and sets up the next irq.
By using the previous sprites position, you can properly chain the irqs down the screen, for much less
"overlapping" bugs.

fungus, awesome. never ever saw a commented mplexer src so far :) how tight sprite formations can you do with it? what if 9 sprites on a row ? :)
edit:
lda $d003 ;get last position of next sprite
clc
adc #$15 ;add 21 lines
cmp $d012 ;we there yet?
I dont get this one, shouldnt we set the Y coord of the next sprite BEFORE it gets displayed? |

Oswald: this is a bug I found in many multiplexer, you need to check that the last line of the previous sprite has been displayed, or the next one will NOT display properly ;)

fungi, the last line of that sprite was already displayed in the prvs frame so no problems.
hmm or is this a way for 9th sprite eliminate? |
