Detailed Description

The default ParaEngine Window.

It can used as an example of how to write main game loop using ParaEngine library.

e.g.

CD3DWindowDefault defaultWin; defaultWin.SetAppInterface(CParaEngineApp::GetInstance());

return defaultWin.Run(hInstance);

Member Function Documentation

CalculateRenderTime()

int ParaEngine::CD3DWindowDefault::CalculateRenderTime	(	double	fIdealInterval,
		double *	pNextInterval
	)

return true if this is a render tick, otherwise false.

Parameters

fIdealInterval	the ideal interval (FPS) when this function will return true at ideal FPS.
pNextInterval	main_loop timer interval.

Returns

frameDelta. if this is bigger than 0, we will render a frame.

tricky: run the main_loop as fast as possible at least 100FPS, so that FPS is more accurate.

define to output interval to log file to change timer implementation.

StartWindowThread()

HRESULT CD3DWindowDefault::StartWindowThread

(

HINSTANCE

hInstance

)

create the default win32 windows for rendering.

and assigning to m_hWnd. window is created in another thread. Since windows uses single threaded apartment, the window procedure should also be in that thread.
