Everything compiles fine, yet nothing shows when I try to run it. I read in an article about a Win32 wrapper that crutial messages can arrive in the wrong order, which is what I believe is happening. What I am trying to do is keep the code that I currently have as intact as possible.
Everything worked before when I kept the window and message handling code seperate from the Spazuh class. What I
think is wrong is my render() loop which calls the PeekMessage function; it may be out of place.
Has anyone else faced this type of problem before? I have looked at how a window is set up in the Irrlicht engine and the process looks similar.
spazuh.h(class declaration):
#include <d3d9.h>
#include <d3dx9.h>
#ifndef SPAZUH_H
#define SPAZUH_H
class Spazuh
{
public:
int init(int width, int height, bool fullscreen);
void render(void);
void exit(void);
private:
HWND hWnd;
WNDCLASSEX wc;
HINSTANCE hInstance;
LPDIRECT3D9 Direct3D_object;
LPDIRECT3DDEVICE9 Direct3D_device;
D3DPRESENT_PARAMETERS present_parameters;
D3DXMATRIX projection_matrix;
};
#endif
spazuh.cpp(functions, Win32/DX init, etc):
#include "spazuh.h"
LRESULT WINAPI MsgProc( HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam );
//
// Initialization
//
int Spazuh::init(int width, int height, bool fullscreen)
{
wc.cbSize = sizeof(WNDCLASSEX) ;
wc.style = CS_HREDRAW | CS_VREDRAW ;
wc.lpfnWndProc = MsgProc ;
wc.cbClsExtra = 0 ;
wc.cbWndExtra = 0 ;
wc.hInstance = hInstance ;
wc.hIcon = 0 ;
wc.hCursor = 0 ;
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1) ;
wc.lpszMenuName = 0 ;
wc.lpszClassName = "Spazuh";
wc.hIconSm = 0 ;
RegisterClassEx( &wc );
// Create the application's window
hWnd = CreateWindow( "Spazuh", "Spazuh",
WS_OVERLAPPEDWINDOW, 0, 0, 800, 600,
GetDesktopWindow(), NULL, wc.hInstance, NULL );
// Show the window
ShowWindow( hWnd, SW_SHOWDEFAULT );
UpdateWindow( hWnd );
Direct3D_object = Direct3DCreate9(D3D_SDK_VERSION);
if( Direct3D_object == NULL )
{
MessageBox(hWnd,"Could not create Direct3D Object","D3D_OBJ ERR",MB_OK);
return 0;
}
ZeroMemory(&present_parameters, sizeof(present_parameters));
present_parameters.Windowed = !fullscreen;
present_parameters.SwapEffect = D3DSWAPEFFECT_DISCARD;
present_parameters.EnableAutoDepthStencil = true;
present_parameters.AutoDepthStencilFormat = D3DFMT_D16;
present_parameters.hDeviceWindow = hWnd;
present_parameters.BackBufferWidth = width;
present_parameters.BackBufferHeight = height;
present_parameters.BackBufferFormat = D3DFMT_R5G6B5;
present_parameters.MultiSampleType = D3DMULTISAMPLE_NONE;
if( FAILED(Direct3D_object->CreateDevice(D3DADAPTER_DEFAULT,D3DDEVTYPE_HAL,
hWnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING,
&present_parameters,&Direct3D_device)))
{
MessageBox(hWnd,"Could not create Direct3D Device","D3D_DEV ERR",MB_OK);
return 0;
}
}
//
// Render loop
//
void Spazuh::render()
{
// Enter the message loop
MSG msg;
ZeroMemory( &msg, sizeof(msg) );
while( msg.message!=WM_QUIT )
{
if( PeekMessage( &msg, NULL, 0U, 0U, PM_REMOVE ) )
{
TranslateMessage( &msg );
DispatchMessage( &msg );
}
else {
Direct3D_device->Clear(0,NULL,D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER,
D3DCOLOR_XRGB(0,0,255),1.0f,0);
Direct3D_device->BeginScene();
Direct3D_device->EndScene();
Direct3D_device->Present(NULL,NULL,NULL,NULL);
}
}
}
//
// Clean-up
//
void Spazuh::exit()
{
UnregisterClass( "Spazuh", wc.hInstance );
//TODO: finish
}
LRESULT WINAPI MsgProc( HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam )
{
switch( msg )
{
case WM_DESTROY:
PostQuitMessage( 0 );
return 0;
}
return DefWindowProc( hWnd, msg, wParam, lParam );
}
Note that MsgProc is not of the Spazuh class. All the necessary structures (WNDCLASSEX, PRESENT_PARAMETERS, etc) are filled here.
main.cpp:
#include "spazuh.h"
int WINAPI WinMain( HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow )
{
Spazuh *spazuh;
spazuh->init(800, 600, false);
while(1)
{
spazuh->render();
}
return 0;
}
Sorry for the long post and thanks in advance.
