Sometimes a programmer will create his own scenemanager instead of defaulting to the device->scenemanager, this was the case for me as I load multiple worlds simultaneously and then swap between which smgr I want to render. Each level creates it's own scenemanager and then only draws that one. It makes short work of loading and destroying menus and levels. Anyhow, the point to this rambling is that I modified the loader code to take a smgr as a parameter and then saved it in the C3DWScene class.
Code: Select all
class C3DWScene
{
public:
C3DWScene();
virtual ~C3DWScene();
< code removed for simplicity>
ISceneManager* m_Smgr;
C3DW_File *m_pSceneFile;
stringc m_strFileName;
stringc m_strTextureRoot;
stringc m_strModelRoot;
};
bool C3DWScene::load(IrrlichtDevice *pDevice, ISceneManager* Smgr, c8 *szFileName, bool bCreateMeshes, bool bCreateLights, c8 *szTextureRoot, c8 *szModelRoot)
{
m_Smgr = Smgr;
c8 *pData;
s32 nFileSize;
< code removed for simplicity>
it is then used something like this
Code: Select all
#pragma once
#include "ZApp.h"
#include "GlobalData.h"
#include "3DWLoader.h"
