Here's another way to do an if-then block statement. It involves only a single jump so it is more efficient (faster) than a gosub if-then:

lets say you want to do this:
IF A==3 OR A > 5 THEN
[block]
...
[/block]

take the opposite of all parts of the condition:
IF A!=3 AND A <=5 THEN GOTO @SKIP

code goes here

@SKIP

Its a little weird, but its faster (use only when speed matters).

I have a new OS in dev called OaSis! it should be done by the 22nd or even sooner. I have personal input from @bigdog00 and it should be a great os! Also, I am currently designing a new logo for my new company, Zombeesoft. (It wont be MS paint this time lol)

Here are 3 simple ways to slide text window.
all 3 shows basic idea of using different methds(sprite, BG layer, Graphic layer)

they simply put(and slide) window on top of grass field(which is rear BG layer).
and text output is simply done by PNLSTR command.

press any button to open and close text window.

here is sprite version.

'turn off bottom panel.

FOR I=0 TO 1:I=!SPCHK(0):NEXT

GOTO @MAINLOOP

it uses 2 big (64x32) sprites and they act as window.
sprite's priority has changed, so window sprites appear under the text.
by the way, you can set/change/load sprite for bottom screen.
sprite bank name for bottom screen is "SPS0" and "SPS1"
for example: LOAD "SPS0:MYSPRITE"
(note:unlike upper screen which has 512 sprites, bottom screen has only 118 different sprites.)

here is Graphic version.

'erase window by drawing line with clear color 0.

'for speed, i used x4 thick filled lines.
FOR I=128 TO 192 STEP 4
GFILL 0,I,255,I+3,0
VSYNC 1
NEXT

GOTO @MAINLOOP

it simply draws white filled box on bottom.
as you draw more filled box upward, it will look like sliding window.
window box is erased with another box with clear color 0
Graphic layer's priority has changed, so Graphic window appears under the text.

here is BG version.

it uses foreground BG layer and use it as window.
draw window box just outside of bottom of screen.
(you can add cool frame on window layer if you want)
it waits outside and will scroll up/down as needed.

I'm trying to save 2 SCR's to my computer. One is the background, the other is foreground. However, they both appear as foregrounds in PTCU.
I'm saving both of the SCR's to my sd card and then opening the PTC files in PetitComputer Utilites. I prefer making maps on my 3DS, so I don't want to make a map on the computer.
How do I make one SCR a background and the other SCR a foreground?

Load one as the background and the other one as the foreground.

Ah, I see. Just had to click the background and foregrounds tabs and load them as such.

i've heard that many programmers wish they'd never learned BASIC because every other language is so different.

I just uploaded a QR to my twitter page below of a Pre-release non-functional GUI demo of OaSis. Unfortunately, i couldnt get the sprite QRs up, oh well.
coughcoughwindowsvistacough

Can you enlarge a BG tile and/or use it as a sprite?

@hamjam00 Windows Vista is not supported and I had to REMIND YOU THAT YOU COULD CALL THAT OASIS OS!!! Duarrahjhfgahharf! btw, he made oasis OS During our programming competition (it was a 20 minute type thing) and I epicly failed... I'll just stick with Cincos! Does anyone even use cincos?

HELP ME PLEASE!!! I try to load a 640X480 png I made to the grp editor on PTCU But nothing happens!!!!!!! What do I do???? BTW I have windows 7 home premium.

I don't really know if this is the problem, but the maximum image size supported by petit computer would be 256*192

I think.

I just want to take a survey. WHO USES CINCOS? The qr code link is back in here a few pages. Bugs? Suggestions? All would be appreciated. I am working on adding a dock (like a Macintosh)

@morphtroid Thanks!
@bigdog00 I dont use it. Ill check it out though .

@Morphtroid It still no works...
Can u plz do it for me?
Here: (click to enlarge)


Yup, these are backgrounds for my Battlewood game. To the others, please do not use.
I will delete this as soon as one of you help me.
Please help!
thanks

@bluerobin2 - Do you have QuickTime installed on your computer? It is necessary for importing images into PTCUtilities. While you can import an image larger than 256x192, it'll only cut out a section of that size. It won't scale down, so you'll have to scale them down yourself before importing.

What doesn't work? Did you have trouble with importing image to PTC Utilities? Did it crash? Having trouble loading with Petit Computer?
Please provide the exact step-by-step process that you did. There are so many points of failure that is possible. You need to be specific or people won't be able to help you.

I'm sure Morphtroid is busy with his game to do your game. Do you really expect people to do your game for free without compensation? Kids today are so spoiled.

I tried it, and it's just like Discostew said, so it certainly works for me. What kind of problem are you having anyway?

It's possible that you're trying to do BG images with GRP, which is wrong. You probably should try to write a tile ripper to create BG tiles from GRP, because BG screens are composed of character tiles, and it won't be full screen capable. You have to set it up yourself.

Since your backgrounds images are pretty simple, why don't you try doing it completely inside Petit Computer? Or just postpone the background images until later.

Try posting QR codes in QR thread. We also have dedicated Petit OS thread. I have my own launcher program, and I don't see why I should get OS program, when it's nothing more than a program launcher program.

Where'd you hear that? What other languages? What language do they wish learned first? Pardon me for not believing you at all!
All the most popular languages are similar to each others. IF-THEN, FOR-NEXT, WHILE-WEND, REPEAT-UNTIL, and so on. There may be some syntax differences, but overall, the logic is the same.

Not to say that there aren't languages that are different, but they aren't popular. I can't see people wishing to have learned LISP, PROLOG, APL. APL? Ugh. Good luck with that!

@ChangeV
Your post is excellent! Do you mind reposting it in Tutorial thread? I'm afraid if you just leave it here, it'll get lost among other postings.

[quote=swordx][quote=swordx][quote=0LD_SK0OL_PUNK]trust me on this: I WILL DO GOOD! I'm an 8th grader. No one else in my grade knows how to do this, so I'm almost guaranteed a good grade.

Oh it was just some mythology-based book. I've always loved mythology. I think it was The Serpent's Shadow. lol I find it kinda funny. They say I have an 11th grade to college reading level, but I still enjoy the books based on mythology most. You'd think that I'd prefer more mature books.

I dont really mean to brag, but I've been reading at a college level since first grade, xD and I also currently read 337 words a minute (out loud). Thats 5 words out loud a SECOND! but I LOVED serpents shadow, and i cant wait for your prg to come out!

@Ramstrong
i needed a laugh, so thanks for that. i just heard it floating around me at the retirement home, hence the word "heard". i really didn't take it as gospel when i heard it, but i felt it might have been worth sharing, so whatever.

[quote=swordx][quote=swordx][quote=0LD_SK0OL_PUNK]

Nice! I'm not sure how many words I can read per minute... But that's pretty cool!
