by me pc its giving error's if i knew what to do i won't ask this is new to me what do i ad / change so it does work as expected ? it shoot show a sprite 'player.bmp' whit cursor control

bluatigro

ok done that how do i proseed next ?

case WM\_PAINT :
  hdc = BeginPaint( hwnd , &paint ) ;
  GetClientRect( hwnd , &rect ) ;
  winx = rect.right ;
  winy = rect.bottom ;

  player.bmphdc = CreateCompatibleDC( hdc ) ;

  player.show( hdc ) ;

  DeleteDC( player.bmphdc ) ;

  EndPaint( hwnd , &paint ) ;
  break ;
case WM\_DESTROY :

bluatigro

ok i try it i changed the folowing : player.loadbmpformfil( ,_T("player.bmp)) ; my sprite looks like this now :

class Sprite
{
public :
int x , y , w , h ;
bool visable ;
HBITMAP hbmp ;
HDC bmphdc ;
Sprite(){;}
void loadbmpfromfile( HINSTANCE hinstance , TCHAR * file )
{
hbmp = LoadBitmap( hinstance , file ) ;
w = hbmp.i ;
h = hbmp.i ;
visable = true ;
}
void show( HDC hdc )
{
if ( visable )
{
//draw mask whit and [ upper half of bmp ]
BitBlt( hdc , x , y , w , h/2 , bmphdc , 0 , 0 , MERGECOPY ) ;
//draw picture whit or [ lower half of bmp ]
BitBlt( hdc , x , y , w , h/2 , bmphdc , 0 , h/2 , MERGEPAINT ) ;
}
}
bool hit( Sprite spr )
{
if ( x + w < spr.x ) return false ;
if ( x > spr.x + spr.w ) return false ;
if ( y + h < spr.y ) return false ;
if ( y > spr.y + spr.h ) return false ;
return true ;
}
} ;
Sprite player ;

i know this is wrong . how do i do this ? my wm_paint :

case WM\_PAINT :
  GetClientRect( hwnd , &rect ) ;
  winx = rect.right ;
  winy = rect.bottom ;

  player.bmphdc = CreateCompatibleDC(hdc);

  player.show( hdc ) ;

  DeleteDC( player.bmphdc ) ;

  EndPaint( hwnd , &paint ) ;

this can be wrong . how do i do this ?

@ leon : hardware raytracing ? do you meen openGL ? or directx ? in vs2017 i cant do c++ in vb2017 i cant do opengl or directx in that case i won't get reflection and refraction this is also a try at better c++ understanding i can't run c++ on my work pc is there a c++ ide you can start [ and compiles ] from usb ?

@ leon : i m used to basic so the () inplaceof [] update : m44 class [ matrix ] added 3d engine added in the future i wil give a example of a animated avatar
