Unrelated, but I couldn't find the appropriate topic: Congrats to Quigibo for his Puyo Puyo feature!

Yeah true, I think it might be best to have programmers learn to not close parhentesises and brackets when possible. Their code is more readable this way. Only leave them open if you're extremly tight on RAM (if you have a lot of comments, for example).

And yeah congrats for Puyo Puyo feature

If you want a really extreme optimization for or-ing the screen, here it is. It will be noticeably faster and smaller:

Code: [Select]
.# represents the 16-bit or operation L₆→A While -768-L₆ {A}ʳ#{A+L₃-L₆}ʳ→{A}ʳ+1→A End

This is old, but, what does or-ing two buffers do do each other?

It's like TI-Basic Recallpic, where all the black pixels from the second buffer are combined with those in the first buffer.

That can be useful sometimes, for example if you want to do a transition or animation where the entire grayscale turns black.

Question relating to memory storage and displaying screen:
I want to store, display, and manipulate a 64x64 portion of the screen.
Specifically, I want to take data I have stored in L1, copy it over to the buffer or backbuffer, then use Dispgraph to update the screen, or take data from the buffer and copy to L1.
This part I'm fairly certain I can do, using the code below (which I haven't actually tested yet)

Code: [Select]

For(Z,0,15)
    Copy({Z*24+L6},{Z*16+L1},16)
End

but if anybody sees a problem (or has a better way of doing this), I'd be grateful.

Also, the data in L1, I want to be able to manipulate bit by bit. So if I were to have this snippet of data:
F32C
I want to be able to treat it like this:
1111
0011
0010
1010
(Just to make sure I have my terminology down, this would be equal to ~~2 nibbles or 1 byte or 16 bits~~ Edit: 4 nibbles, 2 bytes, 16 bits.)
In this format, I'd like to do things like check around a specific entry to see the total value of the bits 'surrounding' it (if it were treated like a matrix).
However, I don't know how I would do this.

In summary:
1) Request for possible better alternative to my routine
2) Request to take data stored in L1, and manipulated it on the bit level.

Sorry if this isn't making much sense.

Well that would actually be 2 bytes (so 4 nibbles and 16 bits). 1 bytes would be 8 bits. Otherwise, you were right.

And I believe there is a bit-reading command in Axe, but I haven't used it so I can't be of much help there.

Michael_Lee · « **Reply #1522 on:** November 25, 2010, 11:25:02 am »

Ah, thanks, FinaleTI. I knew I made a mistake somewhere...

Hmm, bit-reading command?
I'm not seeing it... (unless it's all those esoteric commands in the 'Advanced Math' section of the commands list...)

squidgetx · « **Reply #1523 on:** November 25, 2010, 11:27:31 am »

The bit reading command's syntax is as follows:

EXP1eEXP2 where EXP1 is the pointer (or it could be inline data) and EXP2 is the bit number (0-7) of the pointed to byte. So if you wanted to read the 1st bit of the byte in L1 you would use L1e1

As for writing to bits, this thread might help

Oh and you don't need the curly brackets in the arguments of your Copy command

calcdude84se · « **Reply #1524 on:** November 25, 2010, 11:30:34 am »

You work with bytes, not nibbles (A nibble is four bits. There are two nibbles to a byte.)
Also, Copy( works like "Copy(SOURCE,DESTINATION,SIZE)"
So your first code segment is actually this:

Code: [Select]

For(Z,0,63)
  Copy(Z*8+L1,Z*12+L6,8)
End

You have 64 rows, numbered 0-63. 64 bits are 8 bytes, so we multiply Z by 8 then add it to L1. A row on the screen is 96 bits (and therefore 96/8=12 bytes), so we multiply Z by 12 and add L6. The 8 is for the same reason as two sentences ago.

You cannot work directly with bits for the most part. [F32C] is like this, actually:

Code: [Select]

11110011
00101100

To manipulate bits, you need to use e (Euler's e) and e^(
e works like this:

Code: [Select]

b00100000e2which returns 1 because the 2nd bit, from left to right, indexed from 0, is a 1.
e^( works like this:

Code: [Select]

e^(5)which returns b00100000 because the 1 is in the 5th position, from right to left, indexed from 0.

Edit: ninja'd...

I'm in the process of writing menus for the Maxwell's Demon port, and I tried to make a sort of optimized, universal menu. For some reason, it doesn't work.
Thing is, the loop is in a subroutine.
I was wondering if there is a size limit to a subroutine, or are there any commands that won't work in a subroutine.
I'll type out the code, just wanted to get the question out.

nemo · « **Reply #1526 on:** November 26, 2010, 03:31:02 pm »

i'm pretty sure you could put your whole game into a subroutine and it'd still run correctly. since when a subroutine is called all it does is just change a pointer (well, actually a register)to point at the beginning of the subroutine and start executing the code there until it reaches a Return statement.

Darl181 · « **Reply #1527 on:** November 26, 2010, 03:48:55 pm »

A and B are used to select the options, C is the # of options.

Code: [Select]

PRGM:AMENUSRC
.AMENU
Lbl MM
ClrHome
Fix 3
Disp " A GENERIC MENU "
.has to be 16 chars
Fix 2
Disp " Play Game",i," Options",i," Quit"
3→C
Sub(SEL)

If A=1
Disp "GAME"

.Game content here

.End of game, go to main menu
Goto MM
End

.Can nest as so
If A=2
Lbl OPT
Fix 3
Disp "Options         "
Fix 2
Disp " Something",i," Something else",i," Get the point"
3→C
Sub(SEL)
.Responses, may contain more sub-menus
Goto MM
End

If A=3
.last option, has to be quit for it to work correctly
Return
End


Lbl SEL
1→A→B
Output(0,A,5►Char
Repeat getKey(54)
ReturnIfgetKey(15)
A+getKey(1)-getKey(4)→B
!If A=B
!IF B:C→B:End
If B=C+1:1→B:End
Output(0,A," "
.that's 1 space
Output(0,B,5►Char
B→A
Pause 475
End
End
ClrHome
.Return

It displays, I just can't get the ► to move up and down.

should be

Code: [Select]

If C+1=B:1→B:End

Don't forget about (the lack of) order of operations

You're old code added one to whatever the value of B=C was, so that If condition would ALWAYS be true; hence, why you couldn't move the cursor around (because B was getting reset to 1 every iteration)

That might be it...I'll try it.

EDIT...

* Darl181 doesn't like RAM clears

Normally, it wouldn't be a problem, but the archive screwed up as well

Okay, back to normal, just lost the menu thing...which I pretty much have memorized anyway
