You'll also need to update your constants.bas from here in order to use the BG_xxx constants.

My constants.bas shows the BG constants, but I will update anyway... I would like to have the latest updates.

They were incorrect in versions before 1.18F of that file.

Ahhh.... Thank you very much. Saved me from some heartache.

Hey Groovy...

 

I updated the .bas file and made some adjustments to eliminate the CS_CYAN. Still cannot get it to work properly. Perhaps you could lend me a hand.

 

 

I tried the GROM 0 card, but that gave me a black screen. Then I tried using my empty GRAM tile and I got the same result. I am likely missing something, so perhaps some fresh eyes would help?

 

This is the same basic loop I have used for all my screen drawing thus far... The only difference between this iteration (which doesn't work properly) and the others is the use of a BG_xxx. all my other cards are defaulted to the black screen color as a background.

 

Thanks in advance.

Try this :-

        MODE SCREEN_FB     ' Enable foreground/background mode.
        WAIT               ' Only changes on the next VBLANK.
        
        FOR VERT=3 TO 6
            FOR HORZ=1 TO 18
                #BACKTAB(SCREENPOS(HORZ,VERT))=BG_CYAN
            NEXT HORZ
        NEXT VERT

Its also a good programming habit to indent loops so you can easily see what code belongs to what loop.

Sorry to jump in here. what is the #BACKTAB? The IntyBASIC manual says "#BACKTAB array (direct access to screen)"

How does this differ from SCREENPOS(HORZ,VERT) COLOR FG_YELLOW+BG_CYAN, " " ?

#BACKTAB is a predefined IntyBASIC array where index 0 is the top left corner of the screen and index 239 is the bottom right corner. It would be my personal preference to use it instead of print, when writing single cards to the screen.

Thanks, I think I understand. Why do you prefer this over Print?

Its slightly faster for single characters. Looking at the disassembly the use of #BACKTAB array takes two less instructions than the print command in the context that Opry99er is using it.

Lookin good.

Any updates? :-)

[Opry99er]

Unfortunately no. Been so busy lately, just updating the weekly scoreboard in the Bowling League has become almost impossible.

 

The hobby time I HAVE had has gone to gaming with the boy.

 

Will return to this soon... Just need time.
