Fun With Circles
« on: January 09, 2021, 02:13:49 am »
This might have been made before, but I've always wanted to make this. You use your mouse and it starts as a dot and as time goes on that dot makes a  larger and larger circle. And at the same time more of these dots and circles are made non-stop. Wherever the mouse is is where they start out at. I added the ability to copy the image to the clipboard so you can paste it to your graphics program and do whatever you want with it. Here are 2 pictures I made too. Enjoy!

Code: QB64: [Select]
  1. DIM x(500), y(500), c(500), s(500)
  2. DIM image AS LONG
  3. DIM image2 AS LONG
  4. image& = _NEWIMAGE(800, 600, 32)
  5. SCREEN image&
  6. image2& = _NEWIMAGE(800, 600, 32)
  7. _TITLE "Fun With Circles by SierraKen - C to Copy to Clipboard, Left Mouse Button Erases Screen."
  9.     _LIMIT 30
  10.     _PUTIMAGE , image&
  11.     a$ = INKEY$
  12.     IF a$ = CHR$(27) THEN END
  14.         mouseX = _MOUSEX
  15.         mouseY = _MOUSEY
  16.         mouseLeftButton = _MOUSEBUTTON(1)
  17.     LOOP
  18.     IF mouseLeftButton THEN
  19.         FOR ttt = 1 TO 490
  20.             x(ttt) = 0
  21.             y(ttt) = 0
  22.             c(ttt) = 0
  23.             s(ttt) = 0
  24.         NEXT ttt
  25.         CLS
  26.     END IF
  27.     a = INT(RND * 100) + 1
  28.     IF a > 5 THEN
  29.         t = t + 1
  30.         IF t > 490 THEN t = 1
  31.         x(t) = mouseX
  32.         y(t) = mouseY
  33.         s(t) = 1
  34.         c1 = INT(RND * 205) + 50
  35.         c2 = INT(RND * 205) + 50
  36.         c3 = INT(RND * 205) + 50
  37.         c(t) = _RGB32(c1, c2, c3)
  38.     END IF
  39.     FOR tt = 1 TO 490
  40.         s(tt) = s(tt) + 1
  41.         IF x(tt) = 0 AND y(tt) = 0 THEN GOTO skip:
  42.         CIRCLE (x(tt), y(tt)), s(tt), c(tt)
  43.         skip:
  44.     NEXT tt
  45.     IF a$ = "c" OR a$ = "C" THEN
  46.         _AUTODISPLAY

  48.         _CLIPBOARDIMAGE = image2&
  49.         _DISPLAY
  50.         _FREEIMAGE image2&
  51.     END IF

Nice effect. Try - DIM C(500) AS _UNSIGNED LONG  for more colors :)

Nice effect, @SierraKen.  Runs pretty smoothly here, even on my old laptop.

Uncanny, I did about the same thing back in 2015, https://raw.githubusercontent.com/smallbasic/smallbasic.samples/master/graphics%202/follow%20me.bas

only didn't need images.

It's because these kinds of outputs are discoveries, not so much inventions. I hold firmly that if any one of us were stuck working with QB64 on a desert island for 10000 years, he/she would eventually write all the same programs as any other person would.

Yeah I am seeing this in MasterGy's latest, his a little better though :)

LOL awesome B+! The old BASIC compilers were interesting, I had the only ASIC 5.0 programs website online in the 90's (besides All Basic Code's). That used GW-BASIC code and compiled to the old DOS .com unless you changed it to .exe. It was hard to use though.
Yeah I figured that if someone has made this already, they probably never added a _CLIPBOARDIMAGE so people can add graphics to it and save it with their graphics program.

I didn't need the _PUTIMAGE line in the LOOP, so I removed it.

  6. SCREEN image&
  7. image2& = _NEWIMAGE(800, 600, 32)
  8. _TITLE "Fun With Circles by SierraKen - C to Copy to Clipboard, Left Mouse Button Erases Screen."
  10.     _LIMIT 30
  11.     a$ = INKEY$
  12.     IF a$ = CHR$(27) THEN END
  14.         mouseX = _MOUSEX
  15.         mouseY = _MOUSEY

  20.             x(ttt) = 0
  21.             y(ttt) = 0
  22.             c(ttt) = 0

  24.         NEXT ttt

  7.             CIRCLE (x(i), y(i)), i + j, _RGB32(127 + 127 * SIN(r * i), 127 + 127 * SIN(g * i), 127 + 127 * SIN(b * i), 80)

You're getting a lot of mileage out of this palette rotation trick!

Have you considered writing an article on it?
