DirectX 11 Grauer Bildschirm

FERNman

Hey Leute!

Ich bin mal wieder am Direct3D üben, und ich wollte jetzt meine einzige Klasse auf ein paar mehr aufteilen, auch aufgrund der neuen Möglichkeiten. Nun ja, es funktioniert nicht.

Der ganze Code debuggt ohne Probleme, aber wenn ich dann eigentlich einen Boden und einen Lichtfleck sehen müsste, sehe ich auf einmal die Maus und einen grau-Schwarzen Bildschirm. Ich werde unten die InitDirect3D und die InitDirect2D Funktion anhängen... Und das ganze Projekt hochladen.

Wenn jemand so nett wäre, sich meiner anzunehmen und sich den Code anzusehen wäre ich ihm sehr verbunden.

Bist schon lustig, es bringt nichts die Rückgabewerte nur entgegenzunehmen, man muss sie auch prüfen. Welchen Sinn hätten sie denn sonst??
Am einfachsten so:

if(FAILED(hr)){
//Dann halt irgendwas machen, sodass du bemerkst das da ein Fehler ist z.B.
MessageBoxA(0, "Funktion XYZ() ist fehlgeschlagen",0,0);
}

Dann noch schauen welcher Fehler es ist: http://msdn.microsoft.com/de-de/library/windows/desktop/ff476174(v=vs.85).aspx
und anschließend das Problem lösen.
