AMOS Basic V1.3 RLittle starfield demo...RR(These routines have their limitations...R)RJThe "STARS" are only drawn in the first bitplane, but it has the advantage)RJthat you can display BOB's on top of the "STARS" whithout having to save Rthe background of them !R(RHRead the Set Bob command in the AMOS manual for better understanding of Rthis process !RR,No more than 4000 "STARS" can be defined... R)RJThe amount of stars you can display on the screen in 1 VBL depends of the R"X SPEED and Y SPEED parameters... R)RJIf you only use X SPEED (so X SPEED <> 0 but Y SPEED = 0), then 670 STARS Rare the limit.R(RHIf you only use Y SPEED (X SPEED = 0 but Y SPEED <> 0), then 660 STARS Rare the limit.R'RFIf you use both speeds (X SPEED <> 0 AND Y SPEED <> 0), then 520 STARSRare the limit.R!R:You may define more stars but the display will flimmer... R'RFOwners of accelerator cards can display more 'STARS', this is because R4I use the 68000 processor to display the 'STARS' !!!R"R\>@\>\>\,,>F >\>@\>\>\F><4i>>
