Hi Enrico !

How to create games with xHarbour

I used FWH and xHB.


function Games()
local oBmpBackGround, oBmpSprite1, oBmpSprite2

DEFINE WINDOW oWnd

@0,0 bitmap oBmpBackGround FILE "room.bmp" pixel of oWnd

@20,10 bitmap oBmpSprite1 FILE "ball.bmp" pixel of oWnd

oBmpSprite1:lTransparent := .t.

?????????????????????????????
// But Not Transparent //
?????????????????????????????


ACTIVATE WINDOW oWnd

return nil

Thank's

This is a working sample:

Code: Select all  Expand view

#include "Fivewin.ch"


FUNCTION MAIN()

    local oWnd, oBrush, oSprite, oTimer

    DEFINE BRUSH oBrush;
           FILE "c:\fwharbour\bitmaps\backgrnd\beach.bmp"

    DEFINE WINDOW oWnd;
           BRUSH oBrush

    @ 0, 0 BITMAP oSprite;
           FILE "c:\fwharbour\bitmaps\fdem5.bmp";
           PIXEL NOBORDER

    oSprite:lTransparent = .T.

    DEFINE TIMER oTimer OF oWnd;
           INTERVAL 10;
           ACTION MOVESPRITE( oWnd, oSprite )

    ACTIVATE WINDOW oWnd;
             ON INIT oTimer:Activate()

    RELEASE TIMER oTimer

    RETURN NIL


STATIC FUNCTION MOVESPRITE( oWnd, oSprite )

    LOCAL aWndRect := GETCLIENTRECT( oWnd:hWnd )

    LOCAL nWndWidth  := aWndRect[ 4 ] - aWndRect[ 2 ]
    LOCAL nWndHeight := aWndRect[ 3 ] - aWndRect[ 1 ]

    LOCAL nXPos, nYPos

    STATIC nXStep := 5
    STATIC nYStep := 5

    nXPos = oSprite:nLeft + nXStep
    nYPos = oSprite:nTop + nYStep

    IF nXPos < 0
        nXPos = 0
        nXStep = -nXStep
    ENDIF

    IF nYPos < 0
        nYPos = 0
        nYStep = -nYStep
    ENDIF

    IF nXPos + oSprite:nWidth >= nWndWidth
        nXPos = nWndWidth - oSprite:nWidth - 1
        nXStep = -nXStep
    ENDIF

    IF nYPos + oSprite:nHeight > nWndHeight
        nYPos = nWndHeight - oSprite:nHeight
        nYStep = -nYStep
    ENDIF

    oSprite:Move( nYPos, nXPos, , , .T. )

    RETURN NIL

Thank's Enrico,

but the BMP size must fixed with window size.
when it not fixed the brush makes tiles on window surfaces.

Hi Areang,

Try this:

Code: Select all  Expand view


...
  IF nYPos + oSprite:nHeight > nWndHeight
        nYPos = nWndHeight - oSprite:nHeight
        nYStep = -nYStep
    ENDIF

    oSprite:refresh()  &&<<<--- Inside This

    oSprite:Move( nYPos, nXPos, , , .T. )

    RETURN NIL


Regards,

Rossine.

Hi Enrico,

It is possible, using FREEIMAGE.DLL capture the image that this in a determined window (dialog/window) and record-her in the format. JPG?

Excuse me. I am using a translator

Hi Enrico.

For the future the game is the good way for all clipper needed.
Just move the image object, click object, show object, hide object, rotate, scale and more. Play the sound and video file.

Think's the object are : image, sound and video

Can you make the lib for this ?

And I will buy the lib from you.

Thank's
