hmm...I guess he tried out animated sprites

That is AWESOME i cant believe the speed!!!

I had no idea xLIB could enable things to work so fast!

Like i said on IRC:

But, have i opened up a dark portal, pathing the way for an endless wave of BASIC rpg's that are actually 'playable'???

Hehehehe

Brute scrolling demo. It's faster than I thought basic could ever do. Note: the SE is a tiny bit faster than that pic, I altered the gif to reflect SE speed as best I could.

that is pretty cool, I don't get the principal behind it hough...explain it to me?

That's extremely fast! Smoothscrolling is an actual possibility now.

Basicly(hehe) this creates a random map(8,1) on the fly and after scrolling 8pixels fills in the missing colomn. If a large map is randomized before hand it's even faster, but predictable.
On the fly:

Code: Select all

AxesOff
real(0
For(X,8,15
For(Y,0,7
Pxl-On(Y,X
End
End
StorePic 0
real(0
{8,1}->dim([A]
While 1
2rand->[A](1,1
2rand->[A](2,1
real(4,2,2,1
2rand->[A](3,1
2rand->[A](4,1
real(4,2,2,1
2rand->[A](5,1
2rand->[A](6,1
real(4,2,2,1
2rand->[A](7,1
2rand->[A](8,1
real(4,2,2,0
real(2,0,0,0,1,8,11,12,0,8,0,0,1
End

pre-randomizing

Code: Select all

AxesOff
real(0
For(X,8,15
For(Y,0,7
Pxl-On(Y,X
End
End
StorePic 0
real(0
abs(randM(8,30)).2->[A]
While 1
For(A,0,18
real(4,2,2,1
real(4,2,2,1
real(4,2,2,1
real(4,2,2,0
real(2,0,A,0,30,8,11,12,0,8,0,0,1
End
End

Of course in practical use you could make a neat asteroids game or have an overhead map scroll video.

Wow Jim awesome...you too tr1p! Does this mean I will go back to BASIC probably not, but it does at least ensure a bright future for our little BASIC developers...

well, my code has become unmanagable...so I am going to rewrite it with better documentation for myself

crzybl is making a Zelda game with xLib, asked for help with scrolling, so I made some programs, and posted them at his Omnimaga forum (link)... But I figured I might as well show them here as well... The scrolling idea is very similar to Jim e's...

Ok, here's what I've done with Zelda style scrolling...
This one has six programs, is faster (can't tell much of a difference in the scree shot, but on calc you can), and is 33 bytes larger (not a whole lot):

This one has three programs, is slower (can't tell much of a difference in the scree shot, but on calc you can), and is 33 bytes smaller (not a whole lot):

And here are the files (one is .rar compressed, one is .zip compressed, both have all files):
Click which one you want on the page...

Thats excellent work Merthsoft, very nice indeed

.

Some of the things you guys are cooking up with this are impressing me greatly!

This is great, I've been doing some experimentation with this myself, as well as pixel-scrolling, and I think 2-pixel scrolling is fast enough for simpler games. I'm also prety sure that I'll use the Zelda-style scrolling for Aura.

Well, check out what I did with it:

That's an older version, now the guy doesn't disappear when you scroll, he goes with the screen

...
PTI seemed to mess up the HUD at the bottom, it looks better than that...
