I am new in irrlicht and at the moment I am implementing a small scen with Newton where a box moves by a scen in x that is simply a floor and some boxes. The code is executed, but the objects go away downwards and it does not control the collision to me between the objects.
Code is the following one:
Code: Select all
#include <irrlicht.h>
#include <newton.h>
#include <iostream>
#include <dvector.h>
using namespace irr;
using namespace core;
using namespace scene;
using namespace video;

using namespace gui;
// Define all the variables we will be needing
NewtonWorld *nWorld;
IAnimatedMeshSceneNode *carro;
IAnimatedMeshSceneNode *mapa;
const float NewtonToIrr= 32.0f;
IrrlichtDevice* device;
IVideoDriver* driver;
ISceneManager* smgr;
IGUIEnvironment* guienv;
int go=0;
class MyEventReceiver : public IEventReceiver
{
public:
virtual bool OnEvent(SEvent event)
{
if (event.EventType == EET_KEY_INPUT_EVENT)
{
if (event.KeyInput.Key == KEY_ESCAPE && !event.KeyInput.PressedDown )
{
device->closeDevice();
return true;
}
//vector3df v = cube->getPosition();
if (event.KeyInput.Key == KEY_KEY_W && go!=2)
{
//v.Z+=10;
//cube->setPosition(v);
go=1;
return true;
}
if (event.KeyInput.Key == KEY_KEY_S && go!=1)
{
//v.Z-=10;
//cube->setPosition(v);
go=2;
return true;
}
if (event.KeyInput.Key == KEY_KEY_A && go!=4)
{
//v.X-=10;
//cube->setPosition(v);
go=3;
return true;
}
if (event.KeyInput.Key == KEY_KEY_D && go!=3)
{

return false;
}

thanks for the aid.
