is a split sideborder scroll done before??
high party people.
the last days i was bussy with coding a sideborder split scroll. with a split scroll i simply mean a scroll that scrolls the left 20 chars to the left and the right 20 chars to the right. through the sideborders... smooth ofcourse and i only used sprites in the sideborder, so no ugly extented graphics...
not very hard to code but i had some fun... the question i have is this done before and is there a record.. my version holds 25 chars high, and you only can use one speed... it scrolls the whole picture one pixel each frame...
i am curious.
greetings,
Testa

40.875 if I may...
:D
I split hair and you split registers. |

Quote: obviously this isnt a d016 split ;) but more like a rol/asl scroller. (it looks nice tho! :D)
yeps, but totally rol/asl a 40 by 25 chars picture is impossible ofcourse.. i used $d016 splits but not at the badlines. at the badlines , and only at the right half of the picture i use ror to scroll the graphics, so i role 25 * 20 bytes.. the ror speedcode is mixed with the rastercode of the sideborder routine..
i also used different screens to scroll all the charpointers... dma delay is not an option here and read and restore all the charpointers takes too much rastertime, so i used different screens and clever memory management...
to move all the graphics through the sideborder, i use different frames (this is why you can only use one scroll speed) and i also used double buffers for the sprites so you simply can change all the spritepointers at the right moment..
one min point of this story is that you can't show/scroll any new graphics... the distance between both halfs simply gets bigger until the whole picture is gone.... (oswald: i hope this is what you mean)
this way splitscrolling a 25 by 40 chars picture is no problem at all, i am suprised this isn't done before..
it is not hard at all.... well i hope i explained enough now.. becoz i gave away a pefectly nice little effect now,..... but you are welcome....
and one last hint.. you can also use a 52 chars wide sideborder picture, too make it even more cooler...
and when you have scrolled 16 chars and there are 24 chars left you can always switch to a 8 sprite sideborder routine (only sprites) and scroll the remaining chars in different speeds (to polish the effect more)... but if you do this there is not much free memory left i am afraid..... (becoz the remaining 24 graphic chars must be converted to sprites aswell)

it IS a $d016-splitscroller. An easy one 7 pixels, no badline. it was just a proove of concept back then. at time I was in Comic Pirates, PJ Dynamix did that routine with a 2x2-scroller skipping the badline (it's black in the font :D ) and no sideborder. I told him that would have been cool in border and he claimed: Not possible!
Testa: Sure you can do a larger one. just skip the badlines and change the font. remember: april 1993 ;) |

danzig, i am not sure what you mean with bigger, i already used 192 graphics lines and black lines each bad line is not good enough for me.. .. just read the post before yours , everthing is there....
have a nice weekend!
bye

you got me wrong :) i mean you can make it BIGGER than my old 7 pixel version.
but the question was: done before? answer: yes ;)
EDIT: and NO, I don't want a world first entry on codebase for that crap :D |

Oh.. Well, sorry about that.
So then what do you get inbetween the splits, $d021, recycled graphics, or something else entirely? I guess I could spend five minutes to write a test for it myself, but where's the fun in that ;) |

Are you talking about this?
Wicked
Part 0c, on side 2 (shown in the release picture). I think I did 15 1x1 multispeed scrollers, next to a 15 line logo swing. It all uses $d016 and the bad lines are used on the 1x1 side. I forgot how ugly that "big ol' sprite" was in the middle. Think it was also covering some bad screen cuts. It's 10 years old, I didn't know any better :)
I never thought of doing a split scroller in the sideborders, sounds like a nice idea. I won't code it though, I've enough problems with my border routines, haha.
If you need a logo, give me specs, I'd be happy to draw something up for ya... |

Phantom thanks for the offer!.. for this effect i already have found somebody. but if you want, you can make some graphics for the demo i am making?.... would be nice..
about sideborder routines, it really isn't difficult at all, come on and go for it....
about your split effect in Wicked: nice idea and nice little production..
greetings

then again, that's too obvious and with the number of sprites, badlines prevent this from going into the sideborder ofcourse. Still, looks cute. |
