Rotating an object which uses getMeshManipulator()

[nrasool]

Hi All,

I have been looking into the forum which have some very good snippets of code and been very useful. I have tried searching for this issue, but come across a brick wall. I just want to say when I click on the left cursor key, rotate my object by -1 unit

Here is my code which I have

Code: Select all

// INCLUDES ///////////////////////////////////
#include <irrlicht.h>
#include "MastEventReceiver.cpp"
using namespace irr;
using namespace core;
using namespace video;
using namespace scene;

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

// irrlicht specific
IrrlichtDevice *device=0;
IVideoDriver *driver=0;
ISceneManager *smgr=0;
scene::ISceneNode* node = 0;


int main()
{
    // create the device
    MastEventReceiver receiver;
    device = irr::createDevice(EDT_DIRECT3D9 ,dimension2d<s32>(800,600),32,false,true,false,&receiver);
    driver = device->getVideoDriver();
    smgr = device->getSceneManager();
    device->setWindowCaption(L"Psionic Normal Mapping Test");



    ILightSceneNode* light1 = smgr->addLightSceneNode();
    light1->setPosition(vector3df(0,0,-100)); 

    
    IAnimatedMesh* mesh = smgr->getMesh("freebeast//beast.b3d");
    IMesh *tmesh = smgr->getMeshManipulator()->createMeshWithTangents(mesh->getMesh(0));


    //scene::IAnimatedMeshSceneNode* scene = smgr->addAnimatedMeshSceneNode(mesh);
    scene::ISceneNode* scene = smgr->addMeshSceneNode(tmesh);

    //IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode( mesh );
    scene->setMaterialTexture(0,driver->getTexture("freebeast//beast1.jpg") );
    video::ITexture* NormalMap = driver->getTexture("freebeast//n_beast.png");
    driver->makeNormalMapTexture(NormalMap,20.0f);
    scene->setMaterialTexture(1,NormalMap);
    scene->setMaterialType(video::EMT_NORMAL_MAP_TRANSPARENT_VERTEX_ALPHA );
    // scene->setMD2Animation(EMAT_CROUCH_WALK);
    tmesh->drop();

    smgr->addCameraSceneNode(0, vector3df(0,50,-150), vector3df(0,5,0));

    while(device->run())
    {
                        receiver.endEventProcess(); 
                        if (receiver.keyDown(KEY_LEFT))
                        {
                          tmesh->setrotation(0,+1,0);
                        }

                        
                        driver->beginScene(true, true,SColor(0,55,55,55));
                        smgr->drawAll();
                        driver->endScene();
                        receiver.startEventProcess(); 
    }
    device->drop();
    return 0;
}

As you can see I'm using the class from: http://irrlicht.sourceforge.net/phpBB2/ ... hp?t=21657

The reason for doing:

Code: Select all

   IAnimatedMesh* mesh = smgr->getMesh("freebeast//beast.b3d");
    IMesh *tmesh = smgr->getMeshManipulator()->createMeshWithTangents(mesh->getMesh(0));

Was for applying normal mapping on to this object, which its working. So the part of the code which I getting difficulty in, is

Code: Select all

if (receiver.keyDown(KEY_LEFT))
                        {
                          tmesh->setrotation(0,+1,0);
                        }

I'm getting a compile error which says

Code: Select all

 'class irr::scene::IMesh' has no member named 'setrotation' 

Please could someone give me some guidance on this, it would be much appreciated

Many thanks

Meshes are not movable objects, they're simply the geometry data. What you do with the mesh is then provide it to an ISceneNode (smgr->addSceneNode(...mesh...)) which you CAN move around and rotate.

Hi JP, Thanks for the reply, however I have done it, if you check the code you will see

Code: Select all

IAnimatedMesh* mesh = smgr->getMesh("freebeast//beast.b3d");
    IMesh *tmesh = smgr->getMeshManipulator()->createMeshWithTangents(mesh->getMesh(0));


    scene::ISceneNode* scene = smgr->addMeshSceneNode(tmesh); 

That right? Isn't it?

scene->setRotation(vector3df(0,-1,0))..

Not only were u trying to rotate the mesh, not the node, but also you were passing your eular angles as three seperate parameters instead of using a vector3df class.

Case closed...

BlindSide, Thankyou for that.

Much appreciated

Works fine now
