Hello, i am trying to code some graphics for a little game in c++ and winapi / directx9. I have established a background as a surface. Then i put some sprites on the background. The problem is, as i call a function that has to center the screen on the active sprite, it doesn't show the background. Here is the code so far, if you miss an information, please ask and i will answer. First, the part of main, that is called, when user pushes button (winapi)

case ID_ZENTRIEREN:
{
for (int x=0;x<4;x++)
if (Spieler[x].Rundenaktiv==true)
{
Spielx=Spieler[x].posx;
Spiely=Spieler[x].posy;
d3ddev->Clear(0,NULL,D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, D3DCOLOR_COLORVALUE(0.0f,0.0f,0.0f,1.0f), 1.0f, 0);
render_frame_center(hDlg1, Worldposx, Worldposy, Bildschirmbreite, Bildschirmhoehe, Spielx, Spiely);
if (Spieler[x].Mobilart==0) //Schuerfer
{
float Mobilposx, Mobilposy;
Mobilposx=Spieler[x].posx;
Mobilposy=Spieler[x].posy;
render_Schuerfer(oWorldposx, oWorldposy, Mobilposx, Mobilposy);
}
else if (Spieler[x].Mobilart==1) //Frachter
{
float Mobilposx, Mobilposy;
Mobilposx=Spieler[x].posx;
Mobilposy=Spieler[x].posy;
render_Frachter(oWorldposx, oWorldposy, Mobilposx, Mobilposy);
}
else if (Spieler[x].Mobilart==2) //Flugwaechter
{
float Mobilposx, Mobilposy;
Mobilposx=Spieler[x].posx;
Mobilposy=Spieler[x].posy;
render_Flugwaechter(oWorldposx, oWorldposy, Mobilposx, Mobilposy);
}
else if (Spieler[x].Mobilart==3) //Jaeger
{
float Mobilposx, Mobilposy;
Mobilposx=Spieler[x].posx;
Mobilposy=Spieler[x].posy;
render_Jaeger(oWorldposx, oWorldposy, Mobilposx, Mobilposy);
}

                render\_Zeichenak

Hi, i properly have coded a bitmap to be drawn in a control child of a dialogue in WINAPI. Now i want to fit the bitmap, that has to be bigger than the window size, in specific coordinates, lateron i want to make controls that move the picture in the window. My problem is i really don't know where i can set the variables who arrange the picture. Here's the code (only the main, the headers are not neccessary):

#if defined(UNICODE) && !defined(_UNICODE)
#define _UNICODE
#elif defined(_UNICODE) && !defined(UNICODE)
#define UNICODE

addition: i feel like an idiot. Maybe i am one. There must be everything allright. It just misses a ">=" in the function instead of a ">", because the variable is equal 1. So the entrypoint is never beeing reached. I ll change it and then we ll see. Thank you so far, i hope i just gave you an evening with something to smile about. Thanks.

Is it possible that the array int Schadensnummer[] establishs a copy of the member variable of the class RestonaGuldon_Gegner[0]? The class is global, the variable m_Schutzwall is public. The class is capsulated in an array. I dont see a solution so far. it couldnt be that i have to give the array of the class in its own function. i think i forgot something, but i still cant see it. :(

Hi, i made a step per step view on the code. It runs through "Schadensnummer[y]=RestonaGuldon_Gegner[0].Basistrefferermittlung();" and returns 1 after it doesn't enter the line it should

//...
if (m_Schutzwall>1)
{
Einschlagsnummer=1;
m_Schutzwall=m_Schutzwall-1;
return (Einschlagsnummer);
}
//...

it should enter there, because the class array object has .m_Schutzwall>1. But it neither enters and sets Einschlagsnummer to 1 or subtracts the m_Schutzwall by 1. There must be something wrong with my declaration of the array of the class "RestonaGuldon_Gegner[0]" oder initialization of the function "Basistrefferermittlung()". But i can't see what it is. I'm blindfolded. I just did everything how i am used to do and it worked fine till now. I am stunned.

I did that. Debugger s showing the array is filled with "1" in each of the 5 instances.

Hi, i have to ask a question about some codelines, where i have a mistake, because the array of int always returns 1 for every instance and i spent a lot of hours and still cannot find the fail i have maid. I simply post the necessary codelines in hope that someone can put away the wood infront of my head. Inside a modal dialogue, these are the calls

for (int y=0;y<5;y++)
{
Schadensnummer[y]=KlendautKlendaut_Gegner[0].Basistrefferermittlung();
}

The class "KlendautKlendaut_Gegner0" - function Basistrefferermittlung:

int CBasis::Basistrefferermittlung()
{
int Zufallstreffer;
Zufallstreffer=rand()%99+1;
int Trefferchance;

I added these lines. There is still no effect. Please take a look at the code i postet with a thread i made in questions. I think it has something to do with the way i manage the edit control where directx is supposed to render. It would be really nice if you take a look in my other thread. Thanks a lot.

Hello, i tried to fix this, but it still doesn't work. I thougth about it and i guess it could be anything with the ressource file of the dialogue.

The DirectX Code should be in the Static Control "ID_RAUMKARTE31". Maybe i have to add a parameter. Thx & Greetings

Hello, i am trying to handle problem with directX 9 and code:blocks. i searched the internet and after installing the sdk properly and used a tutorial to compile the directx code in an static control window of my winapi program. The IDE doesn't give an error, but instead of compiling a grey window the code only does a black window over the other dialog elements, who won't be compiled properly on screen. The programm doesn't shutdown and the window bar still is in function. Does anyone knows what's to do? Here ist the code in cuts:

void initD3D(HWND hDlg30)
{
d3d = Direct3DCreate9(D3D_SDK_VERSION);

D3DPRESENT\_PARAMETERS d3dpp;    

ZeroMemory(&d3dpp, sizeof(d3dpp));    
d3dpp.Windowed = TRUE;    
d3dpp.SwapEffect = D3DSWAPEFFECT\_DISCARD;    
d3dpp.hDeviceWindow = hDlg30;    

d3d->CreateDevice(D3DADAPTER\_DEFAULT,
                  D3DDEVTYPE\_HAL,
                  hDlg30,
                  D3DCREATE\_SOFTWARE\_VERTEXPROCESSING,
                  &d3dpp,
                  &d3ddev);

}

HRESULT CreateDevice(UINT Adapter, D3DDEVTYPE DeviceType, HWND hFocusWindow, DWORD BehaviorFlags,
D3DPRESENT_PARAMETERS *pPresentationParameters, IDirect3DDevice9 **ppReturnedDeviceInterface);

void render_frame(void)
{
d3ddev->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(70, 70, 70), 1.0f, 0);

d3ddev->BeginScene();    

d3ddev->EndScene();    

d3ddev->Present(NULL, NULL, NULL, NULL);    

}

void cleanD3D(void)
{
d3ddev->Release();
d3d->Release();
}

And this is the dialog code so far:

BOOL CALLBACK RaumkarteProc(HWND hDlg30, UINT message, WPARAM wParam, LPARAM lParam)
{
PAINTSTRUCT ps;

HDC hdcZeichnung;
