Hello,

I couldn't find this information by googling so I'm asking the gurus here.
Are the "and" and "or" operators short-circuited in basic v2?

http://en.wikipedia.org/wiki/Short-circuit_evaluation

I.e. (1 or a=1) will basic evaluate a=1?

You can convert the B/W image directly to a BASIC program which consists solely of PRINT statements (and two POKEs into screen and colour RAM for the bottom-right character), which is much more efficient speed- and memory-wise. That's what I want to do. I think I'll write a little (perl?) script th...

Thanks for the advice.
Is there a tool to convert the coordinates to basic v2 code?

Hello!
What's the best workflow to convert a graphic file (on PC, possibly Linux) to petscii (poxels) basic drawing code?
I'd like to make a compact "graphical" splash screen.

Name: Cento Author: Pallas (OPByte) Released: February 18, 2013 Requirements: Unexpanded VIC-20 Description: The game is made of a board divided into 10x10 squares. Goal of the game is to fill as many squares as possible. You can move horizontally and vertically by 3 squares or diagonally by 2. To ...

Mine is because I like a band called Pallas

Many thanks Heather, that's very kind.
I've managed to solve the problem by taking 5v from the video port, as suggested.
Back to soldering after 20 years was fun!
I'll keep your proposal for other purchases I may need to make in the future
Have a nice weekend

Hello! I've connected the 5v of the video port to the sd2iec and it works
Now I can use the datassette and the SD together.
Thanks everybody!

I think vic-20 lovers average age is... well... surely not under 30, so we should be patient people: waiting a bit for membership won't be a problem

I wasn't satisfied with the time it took to do the "game over" check, so I did a bit of optimization and uploaded the new .prg file.
Now it feels quicker when doing fast moves.
Every single instruction and FOR cycle matters!

Thanks and yes, the plan is to make some more in the future: I really enjoyed making "cento" so it will be fun making other games or little programs like that. If time permits, of course :-) As many said before, the limited resources makes you concentrate on playability instead of appearan...

Thanks!
There is a good thing about programming on the VIC. It's that the programs get finished
On todays environments, there is always something new to be fixed!

Yes, this kind of randomness is OK, but as long as you play the same game, and go back and forth one level, at least the map (if not the monsters) should remain the same. That's not the case of rogue, moria and hangband (I believe it is for diablo instead). On moria you run thru hundreadths of leve...

Games like moria and nethack have full random levels and monsters + artifacts and special monsters. So mostly random but a lot of fun for months of gameplay. But, globally, there is a "pattern" and a "quest" which keeps it "consistent" as a whole. I think that's because...

Hello! I finally made my first game and program for the vic-20 after almost 30 years! It's all basic and petscii for the unexpanded vic. http://www.opbyte.it/vic20/cento-1.png http://www.opbyte.it/vic20/cento-2.png I'd really appreciate any programming advice you can give: there are probably many op...
