Simple locking puzzle
« on: July 12, 2021, 01:39:18 am »
Move the colored items off the screen, or flush with the white goalposts, by click & drag.
A demo of what can be done in less than a hundred lines. 
Code: QB64: [Select]
  1. Dim b(21, 14)
  2. For by = 1 To 20 '                                         initialize
  3.     Read d$
  4.     For bx = 1 To 13
  5.         b(by, bx) = Val(Mid$(d$, bx, 1))
  6.     Next bx
  7. Next by
  8. begin: '                                                   MAIN LOOP
  9. Locate 2, 2: Print "Move "; moves; '                       display
  10. For ty = 1 To 21
  11.     For tx = 1 To 14
  12.         Color b(ty, tx)
  13.         Locate 2 + ty, 18 + tx * 3
  14.         Print String$(3, 219);
  15.     Next tx
  16. Next ty
  17. x = 0: y = 0 '                                             get move
  18.     sx = _MouseX: sy = _MouseY
  19.     If (sx > 0) And (sx < 80) And (sy > 0) And (sy < 25) Then t = Screen(sy, sx, 1)
  20.     If (t > 0) And (t < 5) Then p = t
  21.     lft = _MouseButton(1)
  22.     While lft
  23.         While _MouseInput: Wend
  24.         dx = _MouseX - sx: dy = _MouseY - sy
  25.         If Abs(dx) > Abs(dy) Then x = (dx < 0) - (dx > 0)
  26.         If Abs(dy) > Abs(dx) Then y = (dy < 0) - (dy > 0)
  27.         If x Or y Then Exit Do
  28.         While _MouseInput: Wend
  29.         lft = _MouseButton(1)
  30.     Wend
  31. Loop Until (p > 0) And (x Or y)

  40.         End If
  41.     Next bx
  42. Next by
  43. moves = moves + 1 '                                        make the move
  44. v1 = 1: v2 = 21: v3 = 1: v4 = 14: v5 = 1
  45. If (x > 0) Or (y > 0) Then Swap v1, v2: Swap v3, v4: v5 = -v5

  50.             If (tx > 0) And (ty > 0) And (tx < 14) And (ty < 21) Then b(y + by, x + bx) = p
