custom ISceneNode problem??

[danielmccarthy]

Hi I want to create a health scene node and I have used the custom scene node from the tutorials to start me off but their is a rendering problem? The onRegisterSceneNode method is not being called neither is the render.

Code: Select all

#include "CHealthBar.h"
#include <iostream>
 
using namespace std;
 
    CHealthBar::CHealthBar(scene::ISceneNode* parent, scene::ISceneManager* smgr, s32 id)
        : scene::ISceneNode(parent, smgr, id)
    {
        this->smgr = smgr;
 
        Material.Wireframe = false;
        Material.Lighting = false;
 
        Vertices[0] = video::S3DVertex(0,0,10, 1,1,0,
                video::SColor(255,0,255,255), 0, 1);
        Vertices[1] = video::S3DVertex(10,0,-10, 1,0,0,
                video::SColor(255,255,0,255), 1, 1);
        Vertices[2] = video::S3DVertex(0,20,0, 0,1,1,
                video::SColor(255,255,255,0), 1, 0);
        Vertices[3] = video::S3DVertex(-10,0,-10, 0,0,1,
                video::SColor(255,0,255,0), 0, 0);
 
        Box.reset(Vertices[0].Pos);
        for (s32 i=1; i<4; ++i)
            Box.addInternalPoint(Vertices[i].Pos);
    }
 
    CHealthBar::~CHealthBar()
    {
 
    }
    void CHealthBar::OnRegisterSceneNode()
    {
        if (IsVisible)
            SceneManager->registerNodeForRendering(this);
 
        ISceneNode::OnRegisterSceneNode();
        cout << "Test" << endl;
    }
 
    void CHealthBar::render()
    {
        cout << "Testing" << endl;
        u16 indices[] = {   0,2,3, 2,1,3, 1,0,3, 2,0,1  };
        video::IVideoDriver* driver = smgr->getVideoDriver();
 
        driver->setMaterial(Material);
        driver->setTransform(video::ETS_WORLD, AbsoluteTransformation);
        driver->drawVertexPrimitiveList(&Vertices[0], 4, &indices[0], 4, video::EVT_STANDARD, scene::EPT_TRIANGLES, video::EIT_16BIT);
    }
 
 
    const core::aabbox3d<f32>& CHealthBar::getBoundingBox() const
    {
        return Box;
    }
 
    u32 CHealthBar::getMaterialCount() const
    {
        return 1;
    }
 
    video::SMaterial& CHealthBar::getMaterial(u32 i)
    {
        return Material;
    }
 

Code: Select all

 
    CHealthBar* healthBar = new CHealthBar(this->getObjSceneNode(), this->smgr, 0);
    healthBar->setParent(this->getObjSceneNode());
    healthBar->setPosition(core::vector3df(0, 1, 0));
 
    healthBar->addAnimator(anim);
    anim->drop();

Help please?

Thanks

hi,

is the parent scenenode null? if so you have to set the rootscenenode as parent.

also, you dont show the header file, but those functions need to be virtual

[danielmccarthy]

they are set virtual in the header. And no the parent scene node is not NULL. I don't know why this is happening. The render method is not being called at all

[Seven]

If you post an entire minimal app we can help

[Matix522]

you must turn of automatic culling. its should help.

Code: Select all

 
 healthBar->setAutomaticCulling(false)
 

or in constructor

Code: Select all

 
CHealthBar::CHealthBar(scene::ISceneNode* parent, scene::ISceneManager* smgr, s32 id, bool culling)
     : scene::ISceneNode(parent, smgr, id)
{
    ISceneNode::setAutomaticCulling(culling);
    //rest of your code
}
