开源项目之开源的2D游戏引擎 HGE

HGE游戏引擎是一个基于directX的游戏引擎，它的渲染及逻辑是基于帧回调的框架模式，其提供一些基本的图像操作和输入控制功能。

项目如图：

fontconv测试代码（参数二：文件路径）：

	filelist			*newFile, *nextFile;

	printf("\nHGE Font 1.XX -> 1.6 converter\nCopyright (C) 2003-2006, Relish Games\n\n");

		// Let's rock now!

		hge->System_Start();

		// Delete created objects and free loaded resources

		delete[] pObjects;
		delete fnt;

效果如图：

hge_tut08测试代码：

int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
{
	hge = hgeCreate(HGE_VERSION);

	// Set desired system states and initialize HGE

	hge->System_SetState(HGE_LOGFILE, "hge_tut08.log");
	hge->System_SetState(HGE_FRAMEFUNC, FrameFunc);
	hge->System_SetState(HGE_RENDERFUNC, RenderFunc);
	hge->System_SetState(HGE_TITLE, "HGE Tutorial 08 - The Big Calm");
	hge->System_SetState(HGE_USESOUND, false);
	hge->System_SetState(HGE_WINDOWED, true);
	hge->System_SetState(HGE_SCREENWIDTH, SCREEN_WIDTH);
	hge->System_SetState(HGE_SCREENHEIGHT, SCREEN_HEIGHT);
	hge->System_SetState(HGE_SCREENBPP, 32);

	if(hge->System_Initiate())
	{
		fnt=new hgeFont("font2.fnt");
		
		if(!InitSimulation())
		{
			// If one of the data files is not found, display an error message and shutdown
			MessageBox(NULL, "Can't load resources. See log for details.", "Error", MB_OK | MB_ICONERROR | MB_APPLMODAL);
			hge->System_Shutdown();
			hge->Release();

		}

		hge->System_Start();

		DoneSimulation();
		delete fnt;
	}

	hge->System_Shutdown();
	hge->Release();
	return 0;
}
