well, i got one of my first maps done. it's not much, just something to look at. i press f5 once, and it works fine. i get out and press F5 again and ... the whole program shuts down and it says

dos memory-arena error
memory allocation error
cannot load COMMAND, system halted

the first time i loaded it up (before i set the palette) it works fine if i start it multiple time. but after i added the palette, it started doing this. anyone know what's happening?

- You might have buggy palette setting code. If it's not too much trouble, please post your Palette setting code.

Personally, I use the OUT &H3C8 & OUT &H3C9 commands to update the VGA palette. I don't have problems with that.

- Could also be where you're loading your Map.

That always happens to me when I'm working with graphics. I just make sure to save, then compile. I don't run in the IDE, I just run the executable.

sure... here's the code. by the way, i use palette code that came from pixit, the tile program i use.

first i dim it.

dim pal&(255)

then i load it up and do whatever...

def seg = varseg(pal&(0))
bload "pixit.pal", VARPTR(pal&(0))
for col% = 0 to 255
out &H3C8, col%
out &H3C9, peek(VARPTR(pal&(col%)))
out &H3C9, peek(varptr(pal&(col%)) + 1)
out &H3C9, peek(varptr(pal&(col%)) + 2)
next
def seg

that's the palette code i use. if you want to see all the info about it, download pixit, and look at the readme. note though, if this might be the problem, that currently i am loading up the tiles one at a time. you know,

def seg = varseg(grass%(0))
bload "grass.pic", varptr(grass%(0))

each tile (grass, then floor, and so on) is loaded up immediatley. i haven't yet compiled them. thanks for all your help, i appreciate feedback.

- Okay, I dunno about all of this DEF SEG stuff, but I know it's unnecessary. Use a slightly different palette structure. You can even make it the same size if you're worried about that extra 2 bytes [total 512] from using INTEGERs.

thanks tenshi. i'll try it out as soon as i can.

anyone remember that annoying controls on soc2? well, with a big of brain power, i was able to make a pixel by tile scrolling engine. so what does this have to do with soc2?? well, in soc2, when you hold down the arrow key, you'd keep on going, long after you stop pressing an arrow. the same thing happens to me. if darkdread is here, could he maybe tell me how to bypass this? (i know he managed to bypass it: i saw it on mattress warrior) or if anyone else feels the urge to help me, just post it, or e-mail me at marshall_7ca@yahoo.ca. any help is greatly appreciated!!

- Well actually, the simplest way to avoid it is just to perform a check every time the loop executes to make sure that the key is being pressed.

Barok · Posted: Tue Jan 14, 2003 12:25 am Post subject:

i'm gonna look around to find out about this stuff. i think the problem is that when you hold down on the left or right or whatever, the temporary memory fills up with what you press, and even when you let go of the key, the temp. mem is still full of the key inputs. every time the program loops around to restart the moving engine, it puts press$= "chr$(0) + "k", and the player will move until the temp. mem is empty.

if this is the case, then i gotta find a way to empty the temp. mem before the action starts up again.

i'm gonna insert my engine here. don't be surprised if it's crude or anything. i made it up with little help of tutorials (darkdreads tut. that's all. i couldn't find any tuts on pixel * tile scrolling!!)
[code]
DO
DO
press$ = ""
press$ = INKEY$

LOOP UNTIL press$ <> ""
DO

SELECT CASE press$
CASE IS = CHR$(0) + CHR$(72)
pressup
CASE IS = CHR$(0) + CHR$(80)
pressdown
CASE IS = CHR$(0) + CHR$(75)
pressleft
CASE IS = CHR$(0) + CHR$(77)
pressright
END SELECT[/code]

that's the main part. i put everything else into subs. here they are. i just have the sub for pressing the left key. they're all pretty much the same.

SUB pressleft
z1% = 0
DO
z1% = z1% + 1

redraw
contactright
IF z1% = 20 THEN
z1% = 0
px% = px% - 1
END IF

PUT (px% * 20 - z1%, py% * 20 - z%), joey2%, PSET
WAIT &H3DA, 8
FOR c = 1 TO 500
NEXT c
LOOP UNTIL z1% = 0

END SUB[/code]

- I'd post my map engine here, but even without the subroutine calls to draw the background tiles, NPCs, etc... it's still well over 230 lines long.

- I don't experience the problem you're referring to:

if you ask me, my collision detector is not bad itself. soon, so people can test it out, tell me what's missing, i'll put out a walkaround demo of my rpg.

sure tenshi. i'd love to see your engine!! but don't post it. it'll take up too much space on the boards. just e-mail me your engine at marshall_7ca@yahoo.ca.

note that it's my first engine, and i've spent about two to three hours a day for about three days (6-9 hours total). not to mention i had to make up a lot of this stuff as i went along. what i posted was an uncleaned version of the engine that i have now.

- This is just the Main routine. There're several calls that this routine makes to other stuff.

Barok · Posted: Tue Jan 14, 2003 9:55 pm Post subject:

indeed, that code is huge. mine might be as big as that, give or take a few lines. (that's my whole engine, subs and all though... as i said, e-mail me your whole engine.)

i have no more problems. however, if i have any more problems though, i'll just post it here. so when you see this topic on the top, you'll know that Barok coded himself in a corner, and will need someone's help.
