Can anyone make this program shorter and smoother? I played with it for a while and it's pretty good, but I'm wondering if there's a simpler, better approach to using the ASPECT value. (bplus, I'm looking at you.  )
Code: (Select All)
Option _Explicit ' A Spinning Circle
Screen _NewImage(600, 400, 32)
Dim As Integer b, c, counter ' Playing with Aspects
Dim As Single aspect, adder
Dim As _Unsigned Long col
$Color:32
counter = 0: col = Red
Do
aspect = 1: adder = .015 ' initial values
' ASPECTS 1 TO 70
For c = 1 To 9
For b = 1 To 10 ' redraw circle 10 times adding to the aspect each loop
Cls
aspect = aspect + adder ' increase the aspect by adder
Circle (_Width / 2, _Height / 2), 100, White, , , aspect
Paint (_Width / 2, _Height / 2), col, White
_Limit 110
_Display
Next b
If aspect >= 70 Then Exit For ' @ ~90 degrees drop thru to reverse loops
adder = adder * 2 ' adder amounts have to double after each 10-loop cycle to look right-ish
Next c
' * now reverse the process *
counter = counter + 1
If counter Mod 2 <> 0 Then If col = Red Then col = Green Else col = Red ' flip colors on odd cycles
For c = 1 To 9 ' ASPECTS 70 TO 1
For b = 1 To 10
Cls
aspect = aspect - adder
Circle (_Width / 2, _Height / 2), 100, White, , , aspect
If aspect <= 1 Then Exit For
Paint (_Width / 2, _Height / 2), col, White
_Limit 110
_Display
Next b
adder = adder / 2 '
Next c
counter = counter + 1
If counter = 4 Then counter = 0
If _KeyDown(27) Then System
Loop
System

Yours is nice I think you can cut it in half by eliminating the 2nd loop, seems like you might be able to change aspect like I change xr below.
here is a different approach:
Code: (Select All)
_Title "Spinning Circle" ' b+ 2024-09-10 highlight front edge
Screen _NewImage(620, 620, 32)
_ScreenMove 300, 60
cx = 308: cy = 308: xr = 0: dxr = 1: dyr = 1: yr = 300: c1~& = &HFFFF0000
Do
Cls
FEllipse cx, cy, xr, 300, &HFFFFFFFF
FEllipse 310, 310, xr, 300, c1~&
xr = xr + dxr
If xr > 300 Then dxr = -dxr: xr = 299: cx = 312: cy = 312: _Delay .1
If xr < 0 Then
dxr = -dxr: xr = 1: cx = 308: cy = 308
If c1~& = &HFFFF0000 Then c1~& = &HFF008800 Else c1~& = &HFFFF0000
End If
_Display
_Limit 120
Loop Until _KeyDown(27)
Sub FEllipse (CX As Long, CY As Long, xr As Long, yr As Long, C As _Unsigned Long)
If xr = 0 Or yr = 0 Then Exit Sub
Dim h2 As _Integer64, w2 As _Integer64, h2w2 As _Integer64
Dim x As Long, y As Long
w2 = xr * xr: h2 = yr * yr: h2w2 = h2 * w2
Line (CX - xr, CY)-(CX + xr, CY), C, BF
Do While y < yr
y = y + 1
x = Sqr((h2w2 - y * y * w2) \ h2)
Line (CX - x, CY + y)-(CX + x, CY + y), C, BF
Line (CX - x, CY - y)-(CX + x, CY - y), C, BF
Loop
End Sub
Edit Correction: I was flipping colors too often sorry, should be OK now!
b = b + ...

Can't you just draw your circles, and then use _PutImage to flip them in/out? I swear, that's how somebody did it on here, or over at the old forums, for a coin toss, and the number of lines there were completely minimal.

Most of the program has disappeared into the ether (it was saved as a dropbox file and deleted in the passing of time), but this is basically the main flip process that was discussed.
Might ask Richard Notley aka QWERKY if he still has a copy of that coin toss demo.

@NakedApe I modified your code but don't think it runs as smoothly:
Code: (Select All)
Option _Explicit

Screen _NewImage(600, 400, 32)
Dim As Integer i, x, start, fini, stepper ' Playing with Aspects
Dim As Single aspect
Dim As _Unsigned Long col
$Color:32
Dim asp(1 To 8)
i = 1: x = 1: asp(1) = 1 ' make an array of aspect values that double from 1
While x < 70
i = i + 1: x = x * 2: asp(i) = x
Wend
col = Red: start = 1: fini = 8: stepper = 1
Do
For i = start To fini Step stepper
Cls
Circle (_Width / 2, _Height / 2), 100, White, , , asp(i)
Paint (_Width / 2, _Height / 2), col, White
_Limit 5

Next
If start = 1 Then
start = 8: fini = 1: stepper = -1
If col = Red Then col = Green Else col = Red ' flip colors on odd cycles

Ah fresh morning, fresh mind!
@NakedApe I hope you find this as good as I do! I mod my mod of your code:
Code: (Select All)
Option _Explicit

Screen _NewImage(600, 400, 32)
Dim As Integer i, x, start, fini, stepper, top ' Playing with Aspects
Dim As _Unsigned Long col
$Color:32
Dim asp(1 To 90)
i = 1: asp(1) = 1 ' make an array of aspect values Note: asp(i) = Cos(_D2R(i)) will spin on the other axis
While i < 90
i = i + 1: asp(i) = 1 / Cos(_D2R(i))
Wend
top = i: col = Red: start = 1: fini = top: stepper = 1
Do
For i = start To fini Step stepper
Cls
Circle (_Width / 2, _Height / 2), 100, White, , , asp(i)
Paint (_Width / 2, _Height / 2), col, White
_Limit 60
_Display
Next
If start = 1 Then
start = top: fini = 1: stepper = -1
If col = Red Then col = Green Else col = Red ' flip colors on odd cycles
Else
start = 1: fini = top: stepper = 1
End If
Loop Until _KeyDown(27)
All smoothed out nicely.
