Spectrum Computing

I used your technique of "moving" only attribute memory, and leaving static graphic vertical bars on the bitmap screen. Here is my demo, programed in pure Basic, moving colors data using defadd trick. As you can see, the scroll is in 4pixels increments: https://i.postimg.cc/GBcZ83PP/pru4px...

I use Parallels to install Win10. Then BasinC to edit and debug.

I have released two games with In-Game Beeper Musisc, programed in pure BASIC: Tetris4px https://spectrumcomputing.co.uk/entry/39283/ZX-Spectrum/Tetris4px and Lprint Runaway https://spectrumcomputing.co.uk/entry/42528/ZX-Spectrum/LPrint_Runaway In both it plays one beep note every 25 frames... The t...

Try Sir Fred:

Jump, Swim, run and stop with inertia.
Rope swing. Throw objects using parabola movement...

Amazing for those days!!

Thank you Andrè! This game is programed in Pure Basic, using LPrint technique to rapidly change colors in attribute memory. It only has one Print instruction to update the scoreboard!

Here you are!

my next experiment with 4 pixel movement in Basic:

Tetris4px

viewtopic.php?p=113339

Thanks Andre. Tetris 4 px is a classic tetris clon, but it moves 4 pixels at a time, instead of typical Basic by-character movement. It has in-game music, playing one beep note every 25frames. It can be played by 1 or 2 players at the same time. 9 Different textures available for the pieces, blended...

It is a Micro Master piece!
Waiting to see your next game in Micro- series

Printy is coded en Assembler.

My routine is pure BASIC.

So it has some limitations compared to Printy.

Thank you very much, Andre. In the TAP you will find two CharSets, one containing letter on the left(MSB) of the byte, and the other to the right(LSB). The subroutine is very simple, just one line. First, set the coordinates you want to print at, using: PRINT AT row, col ; Dont forget that semicolon...

Hi,
I might be 2 years late, but, check these tips I use to improve speed in my Basic programs:

If I may ask, how do you draw the ball? I guess it's something more complicated than PRINT AT... It is as simple as a Print At ... But I need 9UDGs to get the sprite in all positions shifted 4pixels https://i.postimg.cc/87D1L985/IMG-20211123-124432.jpg https://i.postimg.cc/K3B2MrJB/IMG-20211123-124...

I believe that "last brick problem" is mostly a feature of Basic implemenations of Arkanoid where ball movement is character based and the ball may move only at 45 degrees. Check out my Arkanoid Back to Basic, it is written in plain BASIC, however, the ball can move at 30°, 45° and 60° an...

Thank you for playing my game!!! tomorrow I will post some of the tricks I use to improve speed in Basic https://ignacobo.itch.io/arkanoid-back-to-basic Waiting for an interesting reading. Tips for Speeding up your basic program: 1- Your main loop should start at the first line of your code 2- Try ...

Cover screen added!

Thank you Rev_Stuart_Campbell

Whaaatttt is that!!!!!!

It is AWESOME!!!!


Can I borrow it and add it to my game!!!!?

Thanks for the detail @IgnaCoBo. I didn't play it for long before, but did you now speed up the bat movement relative to the ball in this new version? It seems so. Before it seemed to me like if you weren't very precisely following where the ball would land laterally then it seemed like you had ver...

Really smooth movement (I was waiting character-based), nice work. BASIC rulez Am I missing something? It seems to be character based movement for me. And the ball always seems to be at 45 degrees despite @Andre Leao's review mentioning varying angle. It's fast for BASIC, but I don't find it playab...
