Actually, on a similar topic to this (and bear with me because I really am pretty new to writing games). Sound effects in games, are these done in a similar way to the music? In my younger years when I did actually try writing my own games the sound would always stop the rest of the program, i.e. th...

As ever I applaud this forum and its forumites always receive many a helpful answer when I pose these (probably newbie) questions...
thanks!

Hi, I've always wondered how the programming for in-game music is achieved. Does the programmer set up an interrupt that jumps to a music routine? Or do you manually jump during the vertical blank? How does the music regulate its tempo if you are just manually jumping every 1/50th second to a music ...

Awesome replies all but not quite the original idea :-) Thanks though, I've realised by now it's not possible. I wanted, as an example, to put the character 'A' on the screen at position x0,y0 in the first frame (out of the 50 frames), then in the 2nd frame, put character 'B' there in the same posit...

Aha, I think I have all the understanding I need now Thanks everyone and sorry it was such a silly/basic question....!

Which is what I wondered. Wouldn't that effectively be 25fps ? Is 25fps not fast enough to fool the human eye?

Thanks, will give Vice ago. I'm programming the much unloved Sharp MZ-80A. It's not even a 6502 or 6510 machine but that doesn't bother me. It has the 'potential' for some great games I think having had nearly none (or at least no truly decent ones) in all its lifetime. The reason I'm asking here is...

Thanks again. Yes, unfortunately I am using your lovely forum to get generic advice that I am 'making fit' to a different machine that doesn't have re-definable character ROM. However, to re-pay all the great advice I will get a VIC emulator and make my very first VIC m/c program to demonstrate this...

and it would still be fast enough if there were multiple instances of this happening across the screen?

sorry for the beginner questions...... and thanks for all the answers so far...

Sorry, yes, the BASIC was just to get the point across. So it's possible in machine code and will not be visible to the eye that it's swapping between two characters? Would you have to wait for vertical blank otherwise get flicker or would it not matter at all in this case as there is no animation?

Hi Vic20-Ian, I was just about to post that I didn't think the original reply to my question quite got the concept. I am after the 1st of your examples, replacing \ with / very quickly to get X. I was about to say that I didn't think it was possible, but maybe the machine's quick enough to do this? ...

Very interesting, I shall check it out thanks!

Just wondering, would it be possible to swap between two ASCII characters that occupy the same x,y position on the screen so quickly that it would fool the eye into believing they occupy the same space at the same time (flicker-free)? Apologies if this is an exceptionally dumb question....
