Re: In the making: Arukanoido – an Arkanoid clone
I have a few questions about the sprites.
Have you programmed your own routine and how many sprites can be displayed at the same time?
I've counted ten so far. Is that right?

PS: The quality of the game is one of the best on the VIC-20, in my opinion.

Re: PRINT 32-bit integer numbers
This is the code so far... I used one of the multiply routines from Toby Lobster... only to play around with them. CLRSCR equ $E55F WRTF equ $E742 ; faster print MVFACC equ $dba2 FLPINT equ $D1BF STROUT equ $CB1E PRTFIX equ $DDCD ; values form 0 to 65000 X - low; A - high STACK equ $0100 *=$1201 dB ...

PRINT 32-bit integer numbers
Hello,
I like to print 32bit integer numbers in assembly.
I read the example on codebase64.org but I don't get correct results. Can anyone help here?
https://codebase64.org/doku.php?id=base ... _to_string
Thank you in advance

Re: 3D Stars
Okay, sorry for the double post. I have found my mistake. The value 1/Z ist calculated in a range from 4-255, if we reduce it to the maxium x value of 168 the routine works fine. Additionally, a second table with 1/Z for Y should be created. :mrgreen: PROJTAB ;byte $FF,$F0 ; 255, 240 ;byte $E8,$D5,$...

Re: 3D Stars
I still have some questions about the 65C02 processor and its instructions.
STZ $20
is the same like
LDA #$00 / STA $20
PHX = STX $FB
PLX = LDX $FB
This ist not clear to me:
BRA XXXX
CLV
BVC XXXX
or can i write
JMP XXXX

Re: 3D Stars
Hi, I found a great example of the 3D Stars on the following page. https://8bitshack.org/post/starfield/ After transferring to the VIC 20 I ran into some problems. The program collapses at some point. If anyone has the time and desire to take a look at it that would be really great. Many greetings a...

Hello, i have converted the 3D Stars routine from the fridge http://www.ffd2.com/fridge/chacking/c=hacking16.txt to VIC BASIC with the MG expansion from Mike. It is so slow. :shock: Does anyone have an idea how to speed this up in BASIC? This is the original code. 10 rem starfield 15 mode16:gron16 2...

Re: WIP: Bubble Bobble
Hi, i think the Commodore VIC20: Software Sprite Stack library is the best address for this. We have no in game scrolling, except when the level changes and I can do that in Assembler. ;-) Or see the book "Programing the VIC" from Compute! on page 390 and 400. I found a comparison video fr...

Re: Sprites in ML
My Assembler load the program with Load"Demo",8 ant not with ,8,1.
Could that be the error?
And how do I change my basic stub to load the program with .8.1?
