Irrlicht Engine

hi all: Tell in my truth,I am a begin learner of IRRLICHT,I already learn all the examples and the namespase "scene" and so on,I kmow we can optimize the scene nodes with octtree etc,but if there is many nodes (e.g camera scene nodes,terrain scene node many Animate model nodes),my problem ...

where can i find the .h file in your program?
like:
#include <dshow.h>
#include <mmstream.h>
#include <amstream.h>
#include <ddstream.h>

I have a .3ds model(square) with one texture in each face,but when i load it with the engine,every face have mang textures,so i have use the mothed smgr->getMeshManipulator()->makePlanarTextureMapping,but texturecoordinate already in disorder,i'm wilder,plense help me! [/url]

when i learn the engine's sdk ,i find the method getMeshCache from the scene::scenemanager,but what the mechanismof it,and what can i do with using it?

I learn from the engine that the param vsync means:
Specifies vertical syncronisation: If set to true, the driver will wait for the vertical retrace period, otherwise not.
but I couldn't understand "the vertical retrace period" ,please help me ?

maybe this program can help you! #include <stdio.h> #include <wchar.h> #include <irrlicht.h> using namespace irr; #pragma comment(lib, "Irrlicht.lib") scene::ISceneNode* node = 0; IrrlichtDevice* device = 0; class MyEventReceiver : public IEventReceiver { public: virtual bool OnEvent(SEven...

dearfriend: If I correctly undersdand what's your problem,I think the mothd like this: every note heve a pos,or static,or dynamic(but in this instance are dynamic notes) ,So now wo could make a Selector to estimate if the between of pos is approached,thereout ,touch off the events what you want!
