Hey, nice posts! Cool little screen savers.

Here's a mystify-type saver in only 5 lines. (6 if you add the delay)
It's looks like a rainbow wave...

Code:

1   IF r = 0 THEN SCREEN 12 ELSE PRINT
2   a$ = MKI$((160 * COS(r)) + 320) + MKI$((100 * SIN(r)) + 300)
3   IF r > 7.2 THEN r = 1 ELSE r = r + .05
4   LINE (CVI(MID$(a$, 1, 2)), CVI(MID$(a$, 3, 2)))-(CVI(MID$(a$, 1, 2)) + 160 * COS(r), CVI(MID$(a$, 3, 2)) + 45 + r * SIN(r)), r
    '=============
    WAIT &H3DA, 8  'add this if not smooth enough for you
    '=============
5   IF INKEY$ = "" GOTO 1 ELSE END

very nice all, although the plasma one updates too slowly with PSET, and some people still don't have an exit condition.

I bet you could add several of those thingies in one spot with those extra lines (you'd only need 2 more.. FOR I%, NEXT I% (for different line patches), DAV.

Here's to some christmas cheer!

Code:

1 SCREEN 12
2 x% = x% + 1
3 angle! = ATN((SIN(x% / 20) * 20) / x%)
4 dist! = SQR(((SIN(x% / 20) * 20) ^ 2) + (x% ^ 2))
5 PSET ((COS(angle! + y!) * dist!) + 320, (SIN(angle! + y!) * dist!) + 240), INT(y!) AND 7
6 y! = y! + 2
7 IF x% > 300 THEN x% = 0 ELSE y! = y! - 2
8 IF INKEY$ = "" THEN GOTO 2

This could _easily_ be compacted into like 4 lines, but it's slow enough as is... (crawls on my dad's 300 -- okay my 1.6 still, tho...)

Nice one dav!

I edited the plasma after seeing that the waves are almost static.

I also added the dynamic translucency....

Code:

'Here's my entry(translucent Plasma!!!)
'I could have made this a lil bit smaller.
'Relsoft
'Note: you may not notice a thing in about 20 secs as its setting
'up the palette.

1 SCREEN 13
2 J& = (J& + 1) AND &H7FFFFFFF
3 IF J& < 257 THEN PALETTE J& - 1, 65536 * INT(32 - 31 * SIN(J& * 3.14151693# / 128)) + 256 * INT(32 - 31 * SIN(J& * 3.14151693# / 64)) + INT(32 - 31 * SIN(J& * 3.14151693# / 32)) ELSE R% = 64 * (((J& AND 1) = 1) OR 1)
4    FOR y% = 0 TO 100
5    FOR x% = 0 TO 160
6            R% = -R%
7            IF J& > 256 THEN PSET (x% + 80, y% + 50), (SIN((x% + R%) / (28)) * 64) + (SIN((x% + R% + (J& MOD 284)) / (45)) * -128) + (SIN((y% + R%) / (16)) * 64)

Paint tiling would do wonders!!!!


BTW, I'm collecting the stuff that you're posting and I'll post it on my site along with your names on it.... :*)

Keep it coming guys!!!

Rel: This time your plasma looks really translucent! You're the best.

BTW: I ripped your sinus palette to make my vortex look better. Here it is:

Code:

'vortex (Kind of..) Antoni Gual 2003
1 SCREEN 13

3 a$ = a$ + CHR$(32 - 31 * SIN((LEN(a$) - 60 * ((LEN(a$) MOD 3) = 2) + 60 * ((LEN(a$) MOD 3) = 1)) * 3.14151693# / 128))
4 CIRCLE (160, 290 - LEN(a$) ^ .8), LEN(a$) / 2.8, LEN(a$) \ 3, , , .5
5 CIRCLE (160, 290 - LEN(a$) ^ .8 + 1), LEN(a$) / 2.8, LEN(a$) \ 3, , , .5

Dav's variables on string are very interesting...
This way particle systems are possible
As this classic starfield:

Code:

'starfield
1 SCREEN 13
2 a$ = STRING$(400 * 6, CHR$(0))
3 IF CVI(MID$(a$, j + 5, 2)) = 0 THEN MID$(a$, j + 1, 6) = MKI$(RND * 20000 - 10000) + MKI$(RND * 20000 - 10000) + MKI$(100 * RND + 1)
4 PSET (160 + CVI(MID$(a$, j + 1, 2)) / CVI(MID$(a$, j + 5, 2)), 100 + CVI(MID$(a$, j + 3, 2)) / CVI(MID$(a$, j + 5, 2))), 0
5 MID$(a$, j + 5, 2) = MKI$(CVI(MID$(a$, j + 5, 2)) - 1)
6 IF CVI(MID$(a$, j + 5, 2)) > 0 THEN PSET (160 + CVI(MID$(a$, j + 1, 2)) / CVI(MID$(a$, j + 5, 2)), 100 + CVI(MID$(a$, j + 3, 2)) / CVI(MID$(a$, j + 5, 2))), 32 - CVI(MID$(a$, j + 5, 2)) \ 8
7 j = (j + 6) MOD (LEN(a$))
8 IF LEN(INKEY$) = 0 THEN 3

:o ... i have to say that's the only and best 3d starfield i've ever seen to operate without a single loop in it.

[wizardlife]

Infiniti Loop:

Code:

1 SCREEN 12
2 FOR a = 1 TO 15
3 PALETTE a, a * 512 + a + (a * 131072)
4 NEXT
5 x! = x! + xc!
6 IF xc! < 1 THEN xc! = xc! + .00004
7 LINE STEP(0, 0)-(COS(x!) * 320 + 320, SIN(x! * 2) * 100 + 240), INT(x!) AND 15
8 IF x! > 150 THEN x! = x! - 150
9 IF INKEY$ = "" THEN GOTO 5

This pwns anything else I've done so far.

I think that's the best one I've ever seen
