@dbox another QB64 to QBJS translation problem.

In attempts to fix the ellipse drawing in QBJS I had to use QBJS ellipse sub because QBJS was messing up my own in QB64.

I WAS using Color statement to change color for drawing triangles in this code:
Code: (Select All)


Option _Explicit

'_Title "Fall Foliage Banner Move Leaves" ' work file for updating

' started 2017-10-21 by bplus as: fall foliage.bas SmallBASIC 0.12.9 (B+=MGA) 2017-10-21



' 2023-08-30 start of QBJS Banner

' 2023-08-31 Logo and Hills added



' 2023-09-01 Fellippe I see contributed allot to orig code with moving leaves

' Also thanks to grymmjack for getting me starting of PFont and font patterns.

' Also thanks to dbox for catching all my errors with QBJS.



' 2023-09-03 try to fix font print to print while leaves are falling

' tweak numbers for falling leaves for more and not too leaden.



' 2023-09-03 FontFlag to signal FPrint is done



' 2023-09-04 do not stop leaves falling when on a tree trunk

' Ran into problems with QBJS handling Point see commented code in MoveLeaf

' So this keeps moving leaves without Point

' Clean up code a bit fix letters shadows, toss junk subs

' Aha! found a way to get leaves off tree trunks = redraw trunks!

' New Type Tree



' 2023-09-05A fix wind and make (less) leaves more responsive to wind

' 2023-09-05 1:40P added pumpkin but cheeky in QBJS



' 2023-09-06 add ships



' 2023-09-07 another attempt to fix ellipse drawing in pumpkin with QBJS

' remove ships, QNJS having a problem with that too!

' to use the damn ellipse draw function in QBJS because it screws up mine in QB64

' chaneg color and everything drawn with it old color is changed too

BUT QBJS starts changing the color of the ellipse line in the pumpkin to the Color statements color value completely ignoring the color I used in ellipse call???
Its supposed to be Black and remain Black. When I change the Color value, the ellipse line changes with it. But finally the correct line shape is showing.

Color glitch using QBJS Ellipse

Getting this stupid ellipse to draw correctly is getting frustrating! I wasted so much time trying to get it working as it does in QB64.

I was able to fix it for QB64 and QBJS by adding a color parameter to fTri sub but are all the 2d graphics from QBJS going to react that way to Color changes ie using a General Color changeValue~& statement?
Or maybe just the ellipse sub?

Hey @blus, I think I see the problem...

The G2D.FillEllipse method takes 6 parameters:

G2D.FillEllipse x&, y&, radiusX&, radiusY& [, rotation& ][, clr~&]

The last two parameters are optional.  But if you want to specify color you should just use 0 for rotation or leave that parameter blank.

Code: (Select All)
G2D.Ellipse cx, cy, lastr, 29 / 35 * pr, 0, &HFF000000
OR

Code: (Select All)
G2D.Ellipse cx, cy, lastr, 29 / 35 * pr, , &HFF000000

OK thanks, but it is odd it draws the ellipse once but changes that color to Color value updated in Color statement. Could be an asset as well as a glitch.

I will try ellipse with black as 6th argument but already changed drawing with Color value ink.

Never did figure out why my own ellipse code didn't draw correctly, I tested the sub independent of all the other code and it worked fine in QBJS.

I'm not sure I understand where the issue is.  I tried to follow the precedent of other drawing commands in QBasic for all of the relevant G2D library drawing commands: if the optional color parameter is left blank it uses the last value set with a Color statement.  Is this not the behavior you are seeing?  Or, perhaps, not the behavior you were expecting?

Hi @dbox every time I changed Color colorValue2, every ellipse drawn using Color colorVlaue1 switched to ColorValue2 as well, without any redraw. You can see it in the pumpkin lines in my last QBJS code link. The Color statement was used to change the light inside eyes, nose, mouth like a candle flicker but the ellipse lines supposed to be and remain black were switching color to same value as the Candle Light Color for eyes, nose and mouth. Update: they were being redrawn, my mistake!

I don't know maybe it was remembering the last Color change and redrawing the ellipse with that color. It wasn't black but I might have misdiagnosed what was happening. Yes I bet! it was using the last color change to redraw the ellipses. OK my bad on that.

But what was wrong with my ellipse code that QBJS couldn't complete the ellipse lines of the pumpkin and I had to resort to G2D.Ellipse in the first place. See old code in banners where I just started drawing the pumpkins. The ellipse lines would not complete along the x axis of ellipse in QBJS.
   

My ellipse code I tried all kinds of +/- 1 to get it to complete the lines

sample of attempted fix
Code: (Select All)
Sub ellipse (CX As Long, CY As Long, xRadius As Long, yRadius As Long, c As _Unsigned Long)
    Dim scale As Single, xs As Single, x As Single, y As Single
    Dim lastx As Single, lasty As Single
    scale = yRadius / xRadius: xs = xRadius * xRadius
    PSet (CX, CY - yRadius), c: PSet (CX, CY + yRadius), c
    lastx = 0: lasty = yRadius
    For x = 0 To xRadius
        y = scale * Sqr(xs - x * x)
        $If WEB Then
                y = y + 1 ' tried -1 too I think
        $End If

        Line (CX + lastx, CY - lasty)-(CX + x, CY - y), c
        Line (CX + lastx, CY + lasty)-(CX + x, CY + y), c
        Line (CX - lastx, CY - lasty)-(CX - x, CY - y), c
        Line (CX - lastx, CY + lasty)-(CX - x, CY + y), c

        lastx = x: lasty = y
    Next
End Sub

Interesting, your ellipse method seems to work fine in qbjs:



Looking at the screenshots it looks like there were a couple of orange filled ellipses being drawn on top of the pumpkin at each cheek.

09-07-2023, 08:12 PM (This post was last modified: 09-07-2023, 08:36 PM by bplus. Edit Reason: Still have artifacts from trying to fix in QBJS )
I took out the recursive calling of pumpkin in case some rogue extra call was being made and then even the carving, just the ellipse fill and ellipsi for pumpkin sections and still get something strange in QBJS:

' started 2017-10-21 by bplus as: fall foliage.bas SmallBASIC 0.12.9 (B+=MGA) 2017-10-21

' 2023-08-30 start of QBJS Banner
' 2023-08-31 Logo and Hills added

' 2023-09-01 Fellippe I see contributed allot to orig code with moving leaves
' Also thanks to grymmjack for getting me starting of PFont and font patterns.
' Also thanks to dbox for catching all my errors with QBJS.

' 2023-09-03 try to fix font print to print while leaves are falling
' tweak numbers for falling leaves for more and not too leaden.

' 2023-09-03 FontFlag to signal FPrint is done

' 2023-09-04 do not stop leaves falling when on a tree trunk
' Ran into problems with QBJS handling Point see commented code in MoveLeaf
' So this keeps moving leaves without Point
' Clean up code a bit fix letters shadows, toss junk subs
' Aha! found a way to get leaves off tree trunks = redraw trunks!
' New Type Tree

' 2023-09-05A fix wind and make (less) leaves more responsive to wind
' 2023-09-05 1:40P added pumpkin but cheeky in QBJS

' 2023-09-06 add ships

' 2023-09-07 another attempt to fix ellipse drawing in pumpkin with QBJS
' remove ships.
' To use the  2d ellipse draw function in QBJS because it screws up my QB64
' change color and everything drawn with it old color is changed too.
' Fixed my fTri function with a Color parameter.

THEIRS:
Code: (Select All)
G2D.Ellipse cx, cy, lastr, 29 / 35 * pr, 0, &HFF000000

YOURS:
Code: (Select All)
ellipse cx, cy, lastr, 29 / 35 * pr, &HFF000000


You're still missing one parameter before 32-bit color which is last.

Your sub headers to draw ellipse:

Code: (Select All)
Sub fEllipse (CX As Long, CY As Long, xRadius As Long, yRadius As Long, c As _Unsigned Long)

Sub ellipse (CX As Long, CY As Long, xRadius As Long, yRadius As Long, c As _Unsigned Long)

As dbox already said, you need "rotation" before "color" parameter.

Aha! I see the issue.  QBJS is not doing implicit rounding when passing a floating point number to a method parameter that has an integer type.  I'll put this on the fix list for the next release.  In the meantime, you could use a workaround like this:

Ah @dbox thankyou once again.

I found a solution using G2D.Ellipse but glad this mystery is solved. It has nagged at me since first encountered.
