Happy Face
« on: May 12, 2020, 11:22:16 pm »
I made another goofy app that might cheer some people up. It shows the, "Have A Nice Day" happy face and you can use the left mouse button to relocate it and also the mouse wheel to change its size. The changing of the size isn't perfect but it's as good as I can get it. Enjoy!

Code: QB64: [Select]
  1. _TITLE "Have A Nice Day! - Use mouse left button to relocate and wheel to change size."
  2. SCREEN _NEWIMAGE(800, 600, 32)
  3. x = 400
  4. y = 300
  5. s = 100
  6. e = 20
  7. m = 65
  8. _LIMIT 1000
  9. GOSUB face:
  11.     mouseWheel = 0
  13.         mouseX = _MOUSEX
  14.         mouseY = _MOUSEY
  15.         mouseLeftButton = _MOUSEBUTTON(1)
  16.         mouseRightButton = _MOUSEBUTTON(2)
  17.         mouseMiddleButton = _MOUSEBUTTON(3)
  18.         mouseWheel = mouseWheel + _MOUSEWHEEL
  19.         IF mouseWheel > 0 THEN
  20.             s = s + 5
  21.             e = e + 1
  22.             m = m + 3
  23.             IF s > 300 THEN s = 300
  24.             IF e > 60 THEN e = 60
  25.             IF m > 185 THEN m = 185
  26.             GOSUB face:
  27.         END IF
  28.         IF mouseWheel < 0 THEN
  29.             s = s - 5
  30.             e = e - 1
  31.             m = m - 3
  32.             IF s < 20 THEN s = 20
  33.             IF e < .5 THEN e = .5
  34.             IF m < 6 THEN m = 6
  35.             GOSUB face:
  36.         END IF
  37.  
  38.         IF mouseLeftButton = -1 THEN
  39.             x = mouseX
  40.             y = mouseY
  41.             GOSUB face:
  42.         END IF
  43.     LOOP
  44.     a$ = INKEY$
  45. LOOP WHILE a$ <> CHR$(27)
  47. face:
  49. PAINT (2, 2), _RGB32(0, 172, 255)
  50. 'head
  51. FOR sz = .25 TO s STEP .25
  52.     CIRCLE (x, y), sz, _RGB32(255, 255, 127)
  53. NEXT sz
  54. 'eyes
  55. FOR sz = .25 TO e STEP .25
  56.     CIRCLE (x - (s / 2), y - (s / 2)), sz, _RGB32(0, 0, 0), , , 1.5
  57. NEXT sz
  58. FOR sz = .25 TO e STEP .25
  59.     CIRCLE (x + (s / 2), y - (s / 2)), sz, _RGB32(0, 0, 0), , , 1.5
  60. NEXT sz
  61. 'mouth
  62. FOR sz = .25 TO 5 STEP .25
  63.     CIRCLE (x, y + sz), m, _RGB32(0, 0, 0), _PI, 2 * _PI
  64. NEXT sz
  65. mouseWheel = 0
  68.

Hi Ken, I wonder if you can change the smile with the mouse wheel?

Yes but it would require a lot of math and a lot of trial and error. You would have to change the circle aspect and also change the start and end radians for the Circle command to where you want the mouth to start and end at. Attached to this I'll add a radians circle chart so you just plug that in to the Circle command. It both has degrees and radians, the radians are the ones with Pi. You also would have to change the aspect number to make the mouth not part of a perfect circle. The aspect number is the very last number on the Circle command. Here is where you can put everything:
CIRCLE [STEP](column, row), radius%, [drawColor%][, startRadian!, stopRadian!] [, aspect!]
