4 Digit Score

[Endless Runner 2600]

Is there a tutorial or guide for displaying a 4 digit score, cause I tried searching the forums and couldn't find any tutorials. I looked for videos on youtube and also couldn't find any.

My tutorial shows how to use the playfield to display two 2 digit scores (colors are funky as it's in attract mode).

 

 

In reply 56 of The Celery Game topic I helped atari2600land convert it for a single 4 digit display.

This is interesting. Was curious as to methods how but never really looked further into it. Cool.

Another method is to put both sprites into 2 copies close mode and position players 0 and 1 so they line up like this:

 

0101

 

then do something like this:

  ldy #7
ScoreLoop:
  sta WSYNC
  lda (ThousandDigit),y
  sta GRP0
  lda (HundredDigit),y
  sta GRP1
  lda (TenDigit),y
  tax
  lda (OneDigit),y
  SLEEP ???          ; delay until the Thousand has been drawn
  stx GRP0           ; replace Thousands with Tens
  sta GRP1           ; replace Hundreds with Ones
  dey
  bpl Score Loop

The value for ??? depends upon the the X position of the score display. It's basically a truncated version of the 6-digit score, which ends up being simpler because you don't need to use VDEL.
