Animated Rainbow Clock/Date

ProphetOfDoom · Post by **ProphetOfDoom** » Mon Jun 30, 2008 4:46 pm

Hi, this was originally written in BB. It's based on a Javascript someone sent me once. I couldn't get it to work on Linux because it wouldn't let me change the font size/face for drawing on the screen, so it's windows only. Basically it's a rainbow clock, that follows the mouse (after a slight delay). It's still a bit rough round the edges. Anyway, enjoy. By the way I was "veganisafreak", I changed the name because I decided I didn't want to be defined by my vegan-ness. Hope this works for you. Enjoy.

Two comments:

1. This is cool code!

2.

"veganisafreak", I changed the name because I decided I didn't want to be defined by my vegan-ness.

I always thought it should have been Veganism-Freak!

This is cool code!

YAy it worked on your computer. I always have this background fear when I post something, that there's some dumb error in it that makes it specific to my computer.

I always thought it should have been Veganism-Freak!

Yes that would at least make sense. I just had to register quickly on the forums to ask some questions and thought that name was as good as any but it started to piss me off.

I am becoming more extreme in my old age tho (I'm 25). I just installed Linux. I hope I don't turn to Communism.

Marco2007 wrote:Really good for someone, who doesn`t eat things, which can cast a shadow

LOL that's a Simpsons reference isn't it? YEs the veganism thing isa bit tricky. I'm surviving mostly on cous cous and coca cola at the moment, and I suspect the Coke is not vegan but I'm in denial about it. It fuels my coding.

Thanks for the encouraging comments both of you.

Really made my evening.

What is this? I get a syntax error on it? Is this assembler by any chance? (If so, I will test with inline asm turned on)

Procedure.f Atan2(a.f,b.f)
FLD a ; This line, syntax error
FLD b ; This line, syntax error

ProcedureReturn
EndProcedure

EDIT. Never mind, it was ASM. :):)

Looks very nice.

Yeah it's sposed to mimic Blitz BAsic's Atan2() function... I copied it off some post on this forum actually

Cool

.

If you want the others to let it start without inline-asm turned on:

Code: Select all

Procedure.f Atan2(a.f,b.f)
   !FLD dword [p.v_a]
   !FLD dword [p.v_b]
   !FPATAN
   ProcedureReturn
EndProcedure

This way it is direct asm.

Your program really looks cool, and would make a really nice clock and date
screen saver like program. I would suggest one little change though that
would be more appealing or readable for the eyes though.

Change the following code:

Code: Select all

 
   ;Text 0,580,Clock\Date$

   For i = 0 To 38
      If *Clock\Symbol[i]\Moving
         *Clock\Symbol[i]\Angle = FMod((*Clock\Symbol[i]\Angle + *Clock\Speed),359.0)
      EndIf

to:

Code: Select all

   ;Text 0,580,Clock\Date$

   For i = 0 To 38
      If *Clock\Symbol[i]\Moving
         *Clock\Symbol[i]\Angle = FMod((*Clock\Symbol[i]\Angle - *Clock\Speed),359.0)
      EndIf

This causes the date to go counter clockwise which is easier to read,
as we read from left to right.

Very nice program though.

yrreti · Post by **yrreti** » Wed Jul 02, 2008 2:04 am

For an interesting screen saver approach, try these changes:

Code: Select all

mx=220
my=220
xr = 480
yr = 360
Repeat
    Delay(18)  ;to lower cpu usage
   ExamineKeyboard()
   ExamineMouse()
   
   If KeyboardPushed(#PB_Key_Escape)
      Break
   EndIf

   EventID.l = WaitWindowEvent(2)

   If EventID = #PB_Event_CloseWindow  ; If the user has pressed on the close button
      End
   EndIf
   
   mc=mc+1 
   If mc=400
      mc=0
      xr = Random(5)*120
      yr = Random(5)*120
   EndIf 
   ;UpdateClock(*Clock,MouseX(),MouseY())
    UpdateClock(*Clock,mx+xr,my+yr)

ProphetOfDoom, thanks very much for posting this code. I've been using it
as a sort of screen saver, with the added changes I made, and I really like it.

ProphetOfDoom · Post by **ProphetOfDoom** » Sun Jul 13, 2008 8:47 pm

Hi all,

Sorry I didn't reply before. I haven't been online much lately and when I do come on, I'm using Linux so I can't test out the changes people have made to my code. It's sooo kewl tho that people are interested enough in my code to hack about with it themselves! Hmm, "sooo kewl", I sound like... hmm...

Anyway thanks and yrreti you're very welcome! You've probably noticed from the commented out bits in my code, it was originally meant to be a screensaver (the Blitz BASIC version) but I gave up on that when I found out BB couldn't draw to the preview window.

Can anyone show how to make this an "official" windows screensaver? One that responds properly to command line options? Is it possible in PB? IIRC Windows kills screensavers when you move the mouse tho, so you'd have to break the link with the mouse position and just move the clock based on randomness or something. I've seen some C tutorials for making screensavers but they look really complicated.

I have coder low self esteem. That's probably why I use BASIC all the time lol. That and I hate all that strcpy() crap.

Anyway, seeya.
