  WHILE Loop vs FOR/NEXT Loop
Posted by: RandomiserUsr - 2022-03-12, 11:05 AM - Forum: Help & Support - Replies (2)

Hi, quick question:


Programming styles aside which performs better at run time, WHILE or FOR/NEXT ?

I will guess with both are the same? :-)

Thanks

the code is here.

I'll release it as a tap file with graphics when its finished.

The game is fully working as it is. just fine tuning everything now.

  The sound effect thread
Posted by: worcestersource - 2022-02-19, 01:03 AM - Forum: How-To & Tutorials - Replies (3)

Hello everyone,

I thought this would be a nifty place to pop some routines to make sound effects without resorting to asm.

Code:
sub soundBwop()

    dim x, y as uByte

    do until x = 255

        out 254, (y * 8)

        let y = x

        do until y > 239

            let y = y + 16

        loop

        let x = x + 1

    loop

end sub

Which makes a nice 'bwop' sound. it'll also change your border colour, so add the border value to the out statement to stop it changing colour. For example, for the a blue border:
Code:
out 254, (y * 8) + 1

You can play around with this, such as changing the 16 for an 8, or making y count down so the loop duration gets longer each time.

  Testing a variable within a range
Posted by: worcestersource - 2022-01-27, 09:14 PM - Forum: Help & Support - Replies (11)

Hello!

I was wondering if there was a better way of testing whether a variable was within a range.

So instead of:

Code:
IF a > 0 and a < 30 then...

There was a neater and/or more memory efficient method? These sorts of tricks that can help us eke out every last drop out of zxbasic. Smile

Cheers,


Steve

  Problem with compiling game
Posted by: retrofan - 2021-12-29, 04:03 PM - Forum: Help & Support - Replies (1)

On the spectrumcomputing forum we are struggling to compile a frogger basic game with Boriel Compiler.
https://spectrumcomputing.co.uk/forums/v...=21&t=6057
We have made some progress (in .bas file), but the game is still far from fully functional.

Any help would be welcome...

  ZXBC to target 128K BIOS ROM
Posted by: RandomiserUsr - 2021-12-27, 03:54 PM - Forum: Help & Support - Replies (2)

Very quick question,

 could ZXBC target a 128K BIOS ROM in the asm compile routines?

I'm expecting a "no" 

thanks
