[IbeNewb]

I wrote this script, and everything compiled fine. But it was crammed and sloppy. So I want to organize it, putting sections in different files (.cpp), and linking them, using classes. But I don't know exactly what to do to achieve this. Can some one help me out?

Here is what I have managed to come up with, and sadly, I get errors. =/

CTerrainNodes.h

#ifndef CTerrainNodes_h
#define CTerrainNodes_h

class CTerrainNodes
{
		public:
			CTerrainNodes();
			void RenderTerrain( ITerrainSceneNode* ); 
};

#endif

CTerrainNodes.cpp

#include "CTerrainNodes.h"

using namespace irr;

#pragma comment(lib, "Irrlicht.lib")


CTerrainNodes::CTerrainNodes()
	{

	}

void CTerrainNodes::RenderTerrain( scene::ITerrainSceneNode* terrain )
	{
		// add terrain(center) scene node
		scene::ITerrainSceneNode* terrain = smgr->addTerrainSceneNode( 
			"tiles/tile.bmp");

		terrain->setScale(core::vector3df(10, 2, 10));
		terrain->setPosition(core::vector3df(0,0,0));
		terrain->setMaterialFlag(video::EMF_LIGHTING, false);

		terrain->setMaterialTexture(0, driver->getTexture("textures/grassdark.bmp"));
		terrain->scaleTexture(1.0f);
		return terrain;
}

Section from Main.cpp

	// Render Terrain
	CTerrainNodes t;
	t.RenderTerrain();

Errors....
