Why Texture2D::Create() pointer is NULL?

Hello I have something weird with my code.
I just code something like this for test:

void test()
{
	Urho3D::Engine *engine = new Urho3D::Engine(g_pEngineContext);
	Urho3D::VariantMap engineParameters;
	engineParameters["FrameLimiter"] = false;
	engineParameters["WindowTitle"] = "Engine";
	engineParameters["LogName"] = "Engine.log";
	engineParameters["FullScreen"] = false;
	engineParameters["ExternalWindow"] = 0;
	if (!engine->Initialize(engineParameters)) return;

	Urho3D::Texture2D *tex = new Urho3D::Texture2D(g_pEngineContext);
	tex->SetSize(2, 2, Urho3D::Graphics::GetRGBAFormat());
};
int main(int argc, char* argv[])
{
	_CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF);
	g_pEngineContext = new Urho3D::Context();
	test();
	return 0;
};

My code crashing in line: “tex->SetSize(2, 2, Urho3D::Graphics::GetRGBAFormat());”
I just debug what exacly crashing, and here you go:
“Texture2D::Create() pointer is NULL. Why?”

I solved this problem but this is really little weird:

I changed:
return Create();
to:
return Texture2D::Create();

and no longer crashing.

I assume this is in OpenGL? Or are you using the default DX11?

Visual Studio can tell you which function Create(); was originally pointed to. Please let us know where that points to.

Also is this the 1.5 stable release or from the master branch?

OpenGL.

master branch.

I not really sure where exacly show me this. but tooltip show me (0x5417cbc0 where body of Texture2D::Create):

but ‘call edx’ still have NULL address.

Well, i definately found a solution.
In OpenGL Application i need set Preprocessor definition: URHO3D_OPENGL
If i not set this then would cause heap corruptions etc…

Did u set Urho to use OpenGL in the cmake build options?

That would be it! The graphics implementation headers are weird in that regard. I’m hoping this gets changed later down the road.
