On May 18, 12:22pm in "The Hog's Back! And this time, he ain't happy!", you warbled: ] Um, last night I thought I'd try and stick an E-tune on top of my star-field, ] and I had been warned that it would probably go over the 1 frame rate at the ] end of every pattern. But mine just seemed to jump all the time, odd huh? ] (not really, just bad coding on my behalf)
Jump all the time... now ain't that strange? :-) ] Originally I had the E-tune at (65536+16384) and my starfield routine at 65536, ] but this just crashed when I called it (god knows why), so I put the E-tune ] in another page, and paged Hi-Men from the screen to the E-tune every frame, ] called it and paged it back. Anny ideas what is happening? I'm pretty sure my ] routine ain't at fault, as it ticks over quite speedily. Probably the e-tune code needs to be in page C. This is just bad coding for such a simple piece of code. Whoever wrote it needs to re-write it. ] (I am using the Index Register though, is this a particularly slow register?) Yes, very much so. Don't use it, if you can help it. Geoff
