Title: Jetpack 8x+ background request
Post by: Matrefeytontias on March 23, 2012, 04:05:23 am
Hi guys !

I'm searching for someone who can convert a whole 96*64 image into 3 or 4 grayscales. I know that's huge, but I don't know if it's possible :-X

Here is the image (it's from Jetpack Joyride) :
(https://encrypted-tbn2.google.com/images?q=tbn:ANd9GcQR5C_Ysk15k50gFSOkEal6BWaOrumi8Pv95Aoaywnf8J1ioiL71w)

I just want the background, not all the sprites. If anyone can do this, just post the image in grayscales, I'll hand-convert it later ;)

Thanks in advance :thumbsup:

This should go in Pixel Art and Drawing (http://www.omnimaga.org/index.php?board=8.0)
Anyways I could give it a try, if you like it then please credit me.

edit Also I just noticed the super weird topic title O.o
edit2: this made me lose the game
edit3: added a "2" for edit2

That's looks nice ! Matrefeytontias, I think you will need to use tiles ?

I agree....but my above sprite should be easy to divide up

I want to use it in a different way : scroll the whole picture (saintrunner, that's awesome :thumbsup: ) using Copy(Pic+offset,L6,offset

So I think I have better to don't use tiles

Glad you like it :) did that in like 5 minutes though! and it feels good to be taking a break from minecraft and getting back to calc stuff :)

Post by: Nick on March 23, 2012, 03:17:21 pm
wOw great! maybe you could have some slightly vertical scrolling, because now you're at the top really fast, or decrease the size of the sprites. but that's just my opinion :)

bon, anyway, this is amazing. i like the exhaust :) maybe the rainbow and other could come too :) (yes i know that game xp )

edit: maybe you could change the topic title by now, since the game is developping :) or change thread of course..

You'd better make the sprite a little smaller.

Post by: Matrefeytontias on March 23, 2012, 04:45:38 pm
In the real game, the enemies are 1.5 times bigger than mine, so it might be easily playable :)
Title: Re: Jetpack 8x+ background request
Post by: Nick on March 23, 2012, 05:42:52 pm
could be, but your screen is about 8 times smaller :)

it really is too big i think, since the field is only like 3 guys high...

but ok, if you don't want to change it, it stays an extremely nice game :)
Title: Re: Jetpack 8x+ background request
Post by: Matrefeytontias on March 24, 2012, 04:33:52 am
Sorry, but the field is like 5 guys high : my chara is high of only 12 pxls :)

EDIT : I saw a problem in your sprite, saintrunner : still my screen is little, the ground where the chara runs might be at the real bottom of the screen, can you change it ? Else I'll use it as it is.

EDIT 2 : I finished convert all in hexa (saintrunner, I'll hate you for that >:D ), and here is the result :
(http://mattias.refeyton.fr/espace-ti/jetpack/background.gif)

As you can see, that's awesome ! :thumbsup:

EDIT 3 : I paste the ground and the bottom of the screen :
(http://mattias.refeyton.fr/espace-ti/jetpack/backgroundFinal.gif)

I think I can fill the blank on the top of the screen by inserting 25% gray between the bottom and the top of the image.

I have some scrolling issues : I want to scroll my pic but I don't really know how to do that. The bitmap() functions is really too slow, and I think of use Horizontal -(BUF) then Copy(BUF), but I don't know how to reblit the same pic at the right of the first (to scroll).

Right now, I have this :
Code: [Select]
:prgmJTPKBG
:Buff(768)->A
:Buff(768)->B
:Copy(Pic1BG,A
:Copy(Pic1BKG,B
:
:Repeat getkey(15)
:Horizontal -(A
:Horizontal -(B
:
:Copy(A
:Copy(B,L3
:DispGraphrr
:End
It works, but only scrolls the pic once. How can I blit the second pic at the right of this ?

You're trying to make a pixelmapping (http://ourl.ca/15124/283447), good luck on that. :P

PS : you don't need thoses buffers. :o
Title: Re: Jetpack 8x+ background request
Post by: Matrefeytontias on March 25, 2012, 07:11:41 am
Actually that's ok, I found 2 hours ago ;D

Yes, I need these buffers because I clear both buffers each cycle, so I use them to keep the pic displayed somewhere (in order to apply Horizontal - on it)

EDIT : Here is what I reach :
(http://mattias.refeyton.fr/espace-ti/jetpack/scroll.gif)

That's not really pixelmapping, though
Title: Re: Jetpack 8x+ background request
Post by: kindermoumoute on March 25, 2012, 01:16:28 pm
So if you use a 1536 bytes buffers, please use it outside the game. Eg. in an appvar that can be deleted at the end of the program. ;)
Title: Re: Jetpack 8x+ background request
Post by: Matrefeytontias on March 25, 2012, 01:20:38 pm
Yeah, but I just saw something : in game, it's slooooooooow <_<

Now, I have this (bit checking) :
Code: [Select]
:.X2t is the buffer 1, Y2t the buffer 2
:.There are 8 empty pixels at the top of the image
:
:DS<(C,2)
:For(r1,7,63)
: {r1*12+X2t}e0→{r1+L2
: {r1*12+Y2t}e0→{r1+L2+64
:End
:
:Horizontal -(X2t
:Horizontal -(Y2t
:
:For(r1,7,63
: {r1+L2} or {r1*12+11+X2t→r2}→{r2
: {r1+L2+64} or {r1*12+11+Y2t→r2}→{r2
:End
:End
:
:Copy(X2t
:Copy(Y2t,L3That leave the game at an normal speed, but now that's the background which is too slow :banghead: how can I have fast speed and fast scrolling ?

I'm not exactly sure how you're doing it, but the way I'm doing the scrolling backgrounds in Essence is I horizontal +/- the buffer, then look through a stored image and copy a column to the screen.
However in your case you might be able to get away with not having a stored copy because it's the same size as the screen.

I'm assuming you can only scroll to the left...
Maybe try this: First check the part of the buffer that's about to be scrolled off the screen.
So if it's scrolling leftthen you'd check the leftmost bit in each row ( {[row#]*12}e0 ), and store the results somewhere.
Horizontal - as needed
Then go back through the bits you checked earlier and effectively copy the column that was scrolled off the screen (on the left) to the other side of the screen (the right), giving the impression of scrolling :) ( this should be possible by working down what you stored earlier and doing pxl-on to the buffer)

He wants probably update screen to display rockets and jetpack every loop.
Title: Re: Jetpack 8x+ background request
Post by: Darl181 on March 25, 2012, 04:12:50 pm
Then he'll probably a stored copy...which he could modify on-the-fly to scroll.
Maybe when he goes to Clrdraw, he could just copy the background to the screen because that writes over whatever's on the buffer in the process ;D

Post by: Matrefeytontias on March 26, 2012, 11:11:29 am
@Darl181 : that's exactly what I did O.O
I just implemented the scrolling in the game and reduce the size of the sprite ( ;D ), and effectively, it's still a bit fast

EDIT : eye candy (it's not that bad on a real calc ;D ) :

Title: Re: Jetpack 8x+ background request
Post by: Nick on March 26, 2012, 12:11:17 pm
that's excellent to see, but i hope that the sprites and the background are better distinguishable..

and i think the size of the sprites is perfect now, you have a better moving area, and it seems more natural with the environment being quite big.
Title: Re: Jetpack 8x+ background request
Post by: Matrefeytontias on March 26, 2012, 12:14:21 pm
Yeah, that's a bit confused, especially with the missile sprite, but I will use Pt-Mask instead of Pt-On in order to have solid white :thumbsup: and as I said, that's better on a real calc.
Title: Re: Jetpack 8x+ background request
Post by: shmibs on March 26, 2012, 12:19:51 pm
you should draw something in up at the top of the screen. right now, when you're starting, it's drawing left over data from whatever was in L1/6 before you started, and to make the sprites better distinguishable you could add white outlines. is this game going to have any more enemies? oh, and you should make the background larger so the two sections of wall are the same size and are seamless.
and it does look pretty good =)
Title: Re: Jetpack 8x+ background request
Post by: Matrefeytontias on March 26, 2012, 12:24:33 pm
Still I have one big image written in hexa (768 bytes hand-wrote >_<) I prefer keep this ;D

Yes of course, there will be 3 enemies : missiles, lasers and zappers, sort of electric bows you'll have to avoid.

And yes, I'll add some 25% grey in the image in order to fill the whole screen.
Title: Re: Jetpack 8x+ background request
Post by: shmibs on March 26, 2012, 01:58:32 pm
you don't need to hand-write it. sourcecoder (http://www.cemetech.net/projects/basicelite/sourcecoder2.php) does a fine job of converting to hex, and then you can paste that into the online editor, export it as a program, send it to your calculator, and recall it to whatever program you like =)

EDIT:
a palette swap, like this, would also help to make your sprites more visible.
Title: Re: Jetpack 8x+ background request
Post by: DJ Omnimaga on March 26, 2012, 03:06:51 pm
Does SourceCoder support grayscale? Otherwise I guess first you would need to separate both layers (have one pic with only black and light gray and the other pic with only black and dark gray). Basically get rid of the dark gray and change light to black in the first, and get rid of light gray and change dark to black in the second (photofiltre lets you do that easily, but I don't know if Gimp and Paint.net have that feature). Save both pics separately then convert to hex.

Also this looks great Matrefeytontias. :D You might want to refresh the grayscale multiple times per frame though so it doesn't look too flickery.
Title: Re: Jetpack 8x+ background request
Post by: Matrefeytontias on March 26, 2012, 03:34:50 pm
I can't refresh several times per frame (with DispGraphrr, right ?), it speeds down too much the whole program :-/

EDIT : what's the ? O.O sourcecoder throws me an error (template file or something) when I load your image, shmibs
Title: Re: Jetpack 8x+ background request
Post by: DJ Omnimaga on March 26, 2012, 06:22:58 pm
Ah ok, sorry to hear. :(

And does the SourceCoder site gives you the error or something? Maybe Kerm messed something up. But it could also be that SourceCoder only supports monochrome (non-grayscale) images.

oh, i didn't think you were actually going to use that. it was just a quick suggestion. here are a couple of versions that actually loop properly, so there's no edge. making it 3 level grey would probably be a better idea, because it would flicker less ad things would be easier to see.

Actually I like the second animated screenshot better, since it looks less flickery. 3 LV gray might be a better idea if you go with that one, though.

Of course you can't, still it's electrized (nor in the real game, as I remember)

Looks really great. I like the enemies and projectiles. That will make a great arcade-style game :)

Lasers added : I think it's quite playable now, but I have to add scores, title screen and transition. Also, I have collision bugs with the lasers :

Come to think of it, the game reminds me of the balloon fighter.

I personally think the gravity is set a bit too high - if you look at the actual game the fysix are a bit floatier.
