Batari Password [WIP]

[+Gemintronic]

As a fallback if no savekey/atarivox is found this is a password system for save games.

 

Right now the intention is to have 8 entries with 64 possible characters (A-Z, a-z, 0-9 and !?)

 

This gives us 6 8-bit variables worth of save game information. There is no checksum built in.

 

UP and DOWN changes the current character.

LEFT and RIGHT changes the current field.

FIRE switches between sets of 32 characters (A-5, a-!)

 

ABCDEFGHIJKLMNOPQRSTUVWXYZ012345
abcdefghijklmnopqrstuvwxyz6789?!

 

Build #6: Thanks to bogax it now correctly displays all 64 characters (I think)

Build #8: Can move between fields. Somehow bogax's bit reversing assembly doesn't like what I'm doing.

Build #9: Blinking cursor!

if curchar < 31 then goto drawlow

[+Gemintronic]

if curchar < 31 then goto drawlow

 

Should be:

if curchar < 32 then goto drawlow

 

Really? That was the self induced error? Thanks, man!

Otay Panky!

 

Build #8 is a functional mock up. Meaning, you can move through all 8 fields and select all 64 characters.

 

I tried reusing bogax's assembly to reverse bits but it ended up garbling portions of the playfield. This isn't anything bogax did. I bet it has to do with me somehow messing the timing up or using resources that his code also needs.

 

So, I had to replace this:

 function wrevhi()
 asm
  tax
  lda PassFontHi,x
  and #$0F
  tay
  lda PassFontHi,x
  lsr
  lsr
  lsr
  lsr
  tax
  lda revhi,y
  ora revlo,x
  rts
end
 return

 data revhi
 $00, $80, $40, $C0, $20, $A0, $60, $E0
 $10, $90, $50, $D0, $30, $B0, $70, $F0
end

 data revlo
 $00, $08, $04, $0C, $02, $0A, $06, $0E
 $01, $09, $05, $0D, $03, $0B, $07, $0F
end

with some generic bB like this:

swap
 result{0} = mytemp{7}
 result{1} = mytemp{6}
 result{2} = mytemp{5}
 result{3} = mytemp{4}
 result{4} = mytemp{3}
 result{5} = mytemp{2}
 result{6} = mytemp{1}
 result{7} = mytemp{0}
 return

functions always use temp1 and temp2 whether they need to or not

If you do something like the version below, if the user holds the joystick in a direction, it will be slowed by "cooldown" but if the user taps in a direction, he or she can move through the characters faster instead of needing to wait:

 

password08_2014y_01m_31d_2044t.bin

 

password08_2014y_01m_31d_2044t.bas

 

 

That way you can get to the character you want quickly and slow down when you need to.

Here it is using the reverse function
(however it only get's called in
one spot so it doesn't really need
to be a function)

Maybe you could use a kernel like the used in Dark Mage http://atariage.com/store/index.php?l=product_detail&p=196

 

The letters look rather crisp and besides you could put a top line saying "PASSWORD"

Dark Mage wasn't made in batari BASIC. I think SpiceWare and other assembly guys were making a 32 character kernel. I don't think it has been released yet. If it were it'd have to be made batari BASIC compatible which is not something I'm capable of.

 

I think some more UI elements like the word "Password" could be made from a sprite. Since this is a generic password system I was thinking I'd leave some details to the game programmer themselves.
