Directx Error Handling


MSDN isn't perfect, but DirectX docs are pretty well-written. You can then throw an exception in your own code if that makes sense for your project. Transcript The interactive transcript could not be loaded. Add to Want to watch this again later? check over here

Once an object is complete, a flag is set and the main thread makes the newly created object available in the public interface of the class. D3D.h: #include #include #include class D3D { public: D3D(HWND hWnd); ~D3D(); ID3D11Device* GetDevice(); ID3D11DeviceContext* GetDevCon(); ID3D11RenderTargetView* GetRenderTarget(); IDXGISwapChain* GetSwapChain(); private: D3D(); D3D(const D3D&); UINT32 m_test; void Clean(); ID3D11Device* Watch QueueQueueWatch QueueQueue Remove allDisconnect The next video is startingstop Loading...

I normally set the debug output level to one below maximum.By the way for textures without an alpha channel DXT1 is half the size of the other DXT formats, and no You can do this by dispatching a compute shader containing an infinite loop, such as the following: cs.hlsl RWBuffer dummyUAV; cbuffer dummyCB {uint zero;} [numthreads(256, 1, 1)] void main(uint3 id : This is the first time I programmed a thing like that so I'm curious to know whether it helped you and what do you think of it. _com_error Description In your first example, none of the output parameters (mswapChain mdevice mdeviceContext) will be set if it fails, so trying to use them after a failure will likely cause a crash.

The constants S_OK and S_FALSE are both success codes. this content I decided not to check the status of DirectX calls during the rendering (I just check, before using a texture for example, that the texture has been correctly loaded, if not,

If an error occurs, some pointers might be invalid when the function exits.

Lots of game development guides talk about how to handle the game objects themselves, like monsters and characters and all that kind of thing.

example: hr = this -> device -> CreateSamplerState(samplerDescriptions[i], &samplerState); if(!SUCCEEDED(hr)) { // error handler here } This code is contained inside a method called GraphicsEngine::AddSamplerStates.

Not the answer you're looking for? The class holds an array of loading threads currently loading objects.

My classes allow me to encapsulate this loading functionality nicely. Advantages This pattern creates less nesting than the "nested ifs" pattern. Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you! If a call fails, the function makes multiple unneeded error checks, instead of exiting the function immediately.

This example uses the SafeRelease function; smart pointers are also a good choice. I would guess the latest Intel driver installer is attempting to bypass ugly "device removed" errors...

Wendy can now be found at Electronic Art's Tiburon studio in Orlando working with some wonderfully talented people on Next Generation consoles. Regardless of which pattern you adopt, robust code will obey the following rules. I need the device and the device context in various parts of the program, but I want to avoid coupling every aspect of my program tightly to that. I figure how I handle resource loading and access will be linked relatively tightly to how I handle the rendering process, and I want to get it right early on to
