How would one check for any key press with a direct key input?
And can any one point me to a good routine to use for title menus like fish7 and alot of the penguins programs use? (yeah I will get a screenie in a few minutes)
basically a text based title screen
I think that the most help that I can give would be to look at days 12 and 22 in Asm in 28 days. Sorry I am still learning z80 also.
Lol no problem any input is welcome I am also being lazy which is half of why I am asking i have looked threw them Just lost track of how to do any key checking and then I never really payed much attention to text displaying... probably should re-read that.
Also for text display look at day 11 for display help.
Also you really look like someone I know at school--wierd
For text display you would just use _PutS and _VPutS, for large font and small font respectively.
Code: ld h,0
ld l,9
ld d,191
ld e,9
ld a,2
call fastline
call iFastCopy
how would I make that smaller my attempts at converting it to
ld hl,** etc failed horridly

Try ld hl,9? That should work.
err more for DE on that list I should say..just looked at HL again and realized that one was easy......
Code: ld hl,9
ld de,(191 * 256) + 9
ld a,2
For bonus conciseness.
@Tari May Ii ask how that works for future knowledge ^_^ (like mathematically speaking I mean)
Multiplying by 256 is the same as shifting left 8 bits. Somewhat easier to visualize if you consider the values in hex (recall that each digit in hex represents 4 bits):
Code: 191 -> 0xBF
256 -> 0x100
0xBF * 0x100) -> 0xBF00
0xBF00 + 0x09 -> 0xBF09
Splitting 0xBF09 back into bytes, that's 0xBF (191) in the high byte (register D in this case), and 0x09 (9) in the low byte (register E).
You could even write a simple macro to do this if you wanted:
Code: #define PACK16(r16, high, low) ld r16, (256 * high) + low
; Alternate version with bitmath (not sure if TASM or Spasm let you do bit-shifts/masks like this, but Brass will)
#define PACK16(r16, high, low) ld r16, (high << 8) | low
Ah that makes much more sense Tari Thank you!
Code:
ld de,(25*256)+55
ld (pencol),de
ld hl,RankW ; points to "win:",0
call vputsc
ld de,(25*256)+71
ld (pencol),de
ld hl,scores :points to the first ,db in scores
call vputsc
ld de,(35*256)+55
ld (pencol),de
ld hl,RankL ;points to "loss:"
call vputsc
ld de,(35*256)+71
ld (pencol),de
ld hl,(scores)+2 :points to second .db in scores
call vputsc
RankW:
.db "Wins:",0
RankL:
.db "Loss:",0
Scores:
.db 01,0
.db 02,0
when I use this I get random chars for my scores. How should I do this so that I get numbers instead?
You're getting character 0x01 and 0x02. Try, for example, DCS routines
VDispHL and
DispLongInt.
Thanks Kerm!
Ok now how would I get a random number between say like 10 and 20?

You would use the Doors CS (well, Ion) iRandom routine, let it pick between 0 and 10, and just add 10 to the result.

somedays I feel not very smart. Thanks again Kerm!

Not a problem, it happens to the best of us. 
Keep those questions coming, and it looks like this is something that will deserve its own Your Projects topic in a very short time!
So next question. I have read it like 50 times but I can not remember where. How does one set up ABS(or any saferam area) to use as variable storage?

Abs? Since when is Abs a safeRAM area? 
And you don't set up safeRAM, you just use it.
