Thanks... that's a heck of a nice Dav program also (after adjusting for the Mac)!

Dav,

I like your Bigball Demo.

Could some of you mac users please run this code and see if SQR causes the same error there?  I've been wondering about all my graphics programs that use SQR now.

Thanks!

Code: (Select All)
'Imageball.bas
'Draws a ball with image& on it
'By Dav for QB64

Screen _NewImage(800, 600, 32)

'Make sample texture& image to use
texture& = _NewImage(250, 250, 32)
'point to the image
_Dest texture&
'draw something there
Cls , _RGB(33, 66, 99)
For x = 0 To _Width Step 25
    For y = 0 To _Height Step 25
        Line (x, y)-Step(50, 50), _RGBA(Rnd * 255, Rnd * 255, Rnd * 255, Rnd * 255), BF
        Circle (Rnd * _Width, Rnd * _Height), 5 + Rnd * 20, _RGB(Rnd * 255, Rnd * 255, 255)
        Line (x, y)-Step(50, 50), _RGB(0, 0, 0, 0), B
    Next
Next

'go back to main screen
_Dest 0


Do
    ImageBall Rnd * _Width, Rnd * _Height, 75 + Rnd * 75, texture&
    _Limit 60
Loop Until _KeyHit

End

Sub ImageBall (x, y, size, image&)
    'puts image& on a ball.

    'To make it look better, make a temp image to match the size of the ball
    temp& = _NewImage(size * 2, size * 2, 32)
    'put the image& into temp&, stretch to fill
    _PutImage (0, 0)-(_Width(temp&), _Height(temp&)), image&, temp&
    orig& = _Source 'save current _source
    _Source temp& 'switch to temp&
    For y2 = y - size To y + size
        For x2 = x - size To x + size
            If Sqr((x2 - x) ^ 2 + (y2 - y) ^ 2) <= size Then
                clr = (size - (Sqr((x2 - x) * (x2 - x) + (y2 - y) * (y2 - y)))) / size
                c& = Point(x2 - x + size, y2 - y + size): r = _Red32(c&): g = _Green32(c&): b = _Blue32(c&)
                PSet (x2, y2), _RGB(clr * r, clr * g, clr * b)
            End If
        Next
    Next
    _FreeImage temp&
    _Source orig&
End Sub
