Game of Life showroom entry, load *.lif files..

[BdR]

I saw "Life", the latest showroom entry and I thought it was pretty cool..
http://www.glbasic.com/showroom.php?site=games&game=life&lang=en

Unfortunately, it always starts with a random pattern, so I've written a little function to read in *.lif files. These are relatively simple files (plain-text) used to describe and exchange Life pattern. You can download these kind of files from many websites, for example here. I've also created a glbasic.lif, it display the GLBasic logo. (see attachment)

FUNCTION lifload: filename$
// load and interpret a Game of Life pattern file (*.lif)

LOCAL str$, px$, py$
LOCAL i
LOCAL x%, y%, scrx%, scry%

// clear
FOR y%=0 TO heigt%-1
FOR x%=0 TO width%-1
pl%[x%][y%] = 0
NEXT
NEXT

// get middle of screen
GETSCREENSIZE scrx%, scry%

generatie%=0

// open and read file
IF OPENFILE(1, filename$, 1)
WHILE (ENDOFFILE(1) = FALSE)
// read next line
READLINE 1, str$
str$ = str$ + "\n"
// command
IF (MID$(str$, 0, 1) = "#")
// P = position command, for example "#P -3 -1"
IF (MID$(str$, 1, 1) = "P")
str$ = MID$(str$, 3)
i = INSTR(str$, " ")
IF (i <> -1)
// get positions
px$ = MID$(str$, 0, i)
py$ = MID$(str$, i+1)
// string to int
    x% = INTEGER(px$) + (scrx% / 2)
y% = INTEGER(py$) + (scry% / 2)
ENDIF
ENDIF
// TODO: display comment lines on screen? "#D blah bla"
//IF (MID$(str$, 1, 1) = "D")
//ENDIF
ELSE
// cells, for example "*...***"
FOR i = 0 TO LEN(str$)
IF (MID$(str$, i, 1) = "*")
// not out of bounds
IF (x%+i >= 0) AND (y% >= 0) AND (x%+i < scrx%) AND (y% < scry%)
pl%[x%+i][y%] = 1
ENDIF
ENDIF
NEXT //i
y% = y% + 1
ENDIF
WEND
ENDIF

ENDFUNCTION
and in the sourcecode (provided in showroom download) you can replace "GOSUB rrand" with "lifload("glbasic.lif")"

It was written by someone only known as Goos (who is dutch I think, looking at some of the code), no e-mail or anything, so I hope he will read this topic.

Hello BdR,

I was not aware of any .LIF files are out there. But i like the concept and in one evening i trew up this code.
I love to use your lifload code and i made one to read a *.LIF-file from the folder ypu start LIFE from.
I have upgraded then program to the showroom
I  am indeed Dutch.
Greetings from Goos

Great to hear you liked the lifload function and upgraded the program. But I redownloaded the file from the showroom, and I don't know how to load a lif-file with the windows executable (I don't have a GP2x) and the source files seems to be missing too.

Also, all files are in the same folder. I think it would be better to put the font.png in the folder "media" and put all *.lif files in a separate folder.

I am sory my mistake.
I now have updated the folder. It should have the GLBasic program and a GP2X-WIZ and a WIN32 EXE.
I also put de *.LIF files in the <Media> folder.
Thanks for your input.

Here's the program too.
