Topic: Petit Computer

I have a quick question: is it possible to save just music files? I really like making music using different ways (Beaterator and Warioware DIY were both really enjoyable), and if I could make QR music, I could easily share it with others.

@Morphtroid @ejamer Thanks, I'll try and do something and post it here.

I don't think there's a way to save music as a "music file" but you can create the music in an new program file and save it as program.
Then you can share that as QR codes or "append" it to other programs where you want to use it.

Thanks, now I think I'll get it. BTW, I'm looking forward to seeing your Petit Farm game, it sounds cool.

Can Petit Computer really do that?
If there more games like this out there on Petit Computer, I'm sold.

how do you get it to look like
QW
ER
in the end though?

You load it as a sprite (SPU).

Or you could just download Y's Book 1&2 on the Wii VC @Morphtroid.

some people make the mistake of not getting this because they don't know or want to program. those people don't have to do that! there's always the fact that you can scan QR codes to get free indie games. for $8 bucks, this is a steal!

i'd thought i'd solved the problem with my array yesterday, but it turned out i was very, very wrong — aargh this thing is driving me batty. i've been through example after example in several different kinds of BASIC, i've been fiddling with my code for days now, and i've just hit a wall. I know there's an answer, it's just that there's nothing out there that's helping with this specific problem.

this all works fine (minus any weird typos from me typing it into the reply box lol):

CLS
CLEAR

DIM A$(5,4)
FOR B=0 TO 4
FOR C=0 TO 3
READ A$(B,C)
NEXT C
NEXT B

DATA 5,1,2,5
DATA 0,5,4,5
DATA 5,3,5,0
DATA 2,4,5,5
DATA 3,5,5,1

RO=3
PRINT "You are in"
PRINT "Room No. ";RO
@EXITS
IF A$(RO,0)!="5" THEN PRINT "A door leads north.":WAIT 60
IF A$(RO,1)!="5" THEN PRINT "There is an exit to the south.":WAIT 60
IF A$(RO,2)!="5" THEN PRINT "You can leave via the east exit." :WAIT 60
IF A$(RO,3)!="5" THEN PRINT "A doorway leads westward.":WAIT 60

@WHICHWAY
WAIT 60
PRINT "Which direction?":WAIT 60
INPUT "N,S,E,W";D$
IF A$(RO,0)=="5" AND D$=="N" THEN PRINT "You can't go that way!"
IF A$(RO,1)=="5" AND D$=="S" THEN PRINT "You can't walk through walls!"
IF A$(RO,2)=="5" AND D$=="E" THEN PRINT "There's no door there!"
IF A$(RO,3)=="5" AND D$=="W" THEN PRINT "There is no door to the west!"

what I'm having problems with is actual movement throughout this space i've set up. I'm trying to get it to update variable RO (the room i'm currently in) to equal a value from the array I've set up. i've tried just about every variation of the following that I could think of and fiddle around with over the past couple days:

IF D$=="N" THEN RO=A(RO,0)
IF D$=="S" THEN RO=A(RO,1)
IF D$=="E" THEN RO=A(RO,2)
IF D$=="W" THEN RO=A(RO,3)
GOTO @EXITS

and every time i get it working (e.g. not giving me an error due to syntax or subscript out of range), the program will start in the proper room, but as soon as I try to move it puts me into Room 0. It prints the correct responses upon entry of both rooms re: which directions are possible for movement, and it gives the right responses if I try to move in a direction with a value of 5, but I can't switch rooms.

I did manage to get this working by coding it the long way:

IF D$=="N" AND A$(RO,0)=="0" THEN RO=0
IF D$=="N" AND A$(RO,0)=="1" THEN RO=1
IF D$=="N" AND A$(RO,0)=="2" THEN RO=2
IF D$=="N" AND A$(RO,0)=="3" THEN RO=3
IF D$=="N" AND A$(RO,0)=="4" THEN RO=4

IF D$=="S" AND A$(RO,1)="0" THEN RO=0
...

... etc. and so forth, you get the idea. doing it the long way works, but i know there's got to be an easier way of having the array update the room number variable.

I'm not sure, but... You seem to have two varibles A, one is A$ which is being filled with numbers, the other is A which is empty and you're using the empty one on these ifs. That could be just here though.

Gosh, I'm pretty bad at understanding others codes

That is indeed the problem. Change all those A's into A$'s.

Ah, man! Why'd they have to do that?! That's one of the more annoying things about C. Most versions of BASIC will start counting arrays at 1 like how real people count in real life. I guess I'll just use it as if they did start counting at 1 and just ignore the 0 entries. It wastes a little memory that way, but I really don't care unless I'm running up right against the size limit.

That's one of the more annoying things about C

nope, it's the exact same way that computers store things in memory. Offsets always start at zero and it is BASIC that is confusing the issue, not C
In computing, zero does not equal nothing

So who cares how a computer stores it? It's still annoying as heck for the programmers. Just design the programming language to start counting at 1 and automatically adjust it when compiling it to machine code. (This is probably what those other versions of BASIC do.) These are high level languages I'm talking about here, after all.

who cares how a computer stores it?

programmers. offsets apply to other things as well... memory location pointers, hardware registers and a whole lot more. It doesnt make sense to treat arrays any differently, it is after all just a block of memory.

This hasn't been yet released in Europe, right? I've kept my eye on this thread from the beginning although I couldn't see the thread for week as I didn't have access to internet. I'm not sure if it was asked already but how complex games can you make with this application? I know you can make little arcade games but can you do few hours long RPG or Super Mario Bros. clone? I have never used Basic but I guess I could do something little after practicing for a while. I'd be happy if I could make something bigger later. I have very little experience in programming but I've tried a couple of programming languages and have successfully done some modding to few games.
One question that I almost forgot: I think I read somewhere that you can use touch screen in your programs. Is that true? If it is, what can you do with it? Are you able to make it recognize stylus movements like in most of the DS games (touch, swipes, etc.). Is it impossible to make it work like in Pokémon Ranger when you're trying to capture Pokémon (I think I know the answer)?

1- No, it isn't out in Europe yet.
2- In theory, you can make full length games with the right programing tricks and a lot of time, but I don't really think anyone will bother.
3- You can use the touch screen but it is graphically limited (as in, not as easy as the top screen) and you need to find workarounds for that, for the Pokemon Ranger question, read above.

About Petit Farm:

Plants are now 100% functional. Cows are next.

@Morphtroid: Thanks for the answers. I'd like to make a little game using capture mechanics from Ranger but as I thought it would take time and I wouldn't have the skills even after a year of practicing. Glad to see it's still possible at least in theory.

I have one more question to ask. Can you use both screens in your game or are you limited to just one and how does it work? By working I mean, do you have to have some kind of line to set the things to happen on top screen and then use another line to get things on bottom screen? Not really sure how whole programming works with this thing.

I can't wait for Petit Farm man. I am excited. I think your the only one that has anything interesting going on.
