SCROLL leaves previous image when scrolling with transparancy
Normally the SCROLL command will scroll the defined area as specified by the DEF SCROLL command, without leaving any evidence of the previous frame before the scroll, but if you SET TRANSPARENT 0, then scroll, the previous pixels are still visible. This smears the scroll area across the screen.
#manifest: "pc" #displayWidth:1920 #displayHeight:1080 #fullScreen:true #splashScreen:false #fps:false set transparent 0 def scroll 1,20,20 to 100,400,0,5 ink 6 text 50,50,"test" do scroll 1 wait vbl loop
Remove the SET TRANSPARENT 0 line to see how it should work.
