Small graphics programming challenge
« on: April 14, 2022, 10:31:33 am »
' Small programming challenge contained at:
'

' It's a boring hour and a half of some guy creating CSS code for a simple animation to:
' 1) Have 8 icons/pictures rotating in a circle, while pulsing
' 2) when one selected, stop all rotation, the pulsing of the selected item, and
'    identify the selected item
' Use any 8 pix you've got handy, or the flags I've attached here.
Code: QB64: [Select]
  1. Data albania,britain,canada,eu,us,japan,israel,china
  2. Screen _NewImage(800, 600, 32)
  3. For i = 1 To 8
  4.     Read name$(i)
  5.     pix(i) = _LoadImage("f_" + name$(i) + ".png")
  6. td = 1 '                                         throb direction
  7.         mx = _MouseX
  8.         my = _MouseY
  9.         mb = _MouseButton(1)
  10.     Wend
  11.     Cls
  12.     hl = 0 '                                     highlight
  13.     For i = 1 To 8
  14.         r = _D2R(i * 45 + aa) '                  angle in radians
  15.         x = 400 + 200 * Cos(r)
  16.         y = 300 + 200 * Sin(r)
  17.         tt = th '                                temporary throb = current
  18.         If mb And (Abs(x - mx) < 30) And (Abs(y - my) < 30) Then ' selected
  19.             tt = 0 '                             temporary throb off
  20.             hl = 1 '                             highlight on
  21.             _PrintString (x - 26, y - 50), name$(i)
  22.         End If
  23.         _PutImage (x - 30 + tt, y - 30 + tt)-(x + 30 - tt, y + 30 - tt), pix(i), 0
  24.     Next i
  25.     _Display '                                   optional, eliminates flickering
  26.     aa = (aa - (hl = 0)) Mod 360 '               angle advance
  27.     th = th + td '                               throb
  28.     If Abs(th) = 3 Then td = -td '               throb direction
  29.  
It works better if you plug it in.

He stopped halfway...  I've got this on here somewhere, except my version lets you click on the circles and use them as a pop-up menu.  :P
