Custom Scene Node problem

[steveth45]

I made a working custom scene node that is essentially a textured square panel. When I make one, it works fine, when I make more than one, I only see one. I made sure, each time I create a new one, I pass in a unique id number. Any ideas? Here's the code.

Code: Select all

class CFloorSceneNode : public scene::ISceneNode
{

	core::aabbox3d<f32> Box;
	video::S3DVertex Vertices[4];
	video::SMaterial Material;

public:

	CFloorSceneNode(irr_wrapper & parent, s32 id, char * tex, float size)
		: scene::ISceneNode(parent.getSmgr()->getRootSceneNode(), parent.getSmgr(), id)
	{
		Material.Wireframe = false;
		Material.Lighting = false;

        setMaterialTexture(0, parent.getDriver()->getTexture(tex));
        float half_size = size / 2.f;

		Vertices[0] = video::S3DVertex(half_size,half_size,0, 0,0,1, video::SColor(255,255,255,255), 1, 0);
		Vertices[1] = video::S3DVertex(half_size,-half_size,0, 0,0,1, video::SColor(255,255,255,255), 1, 1);
		Vertices[2] = video::S3DVertex(-half_size,-half_size,0, 0,0,1, video::SColor(255,255,255,255), 0, 1);
		Vertices[3] = video::S3DVertex(-half_size,half_size,0, 0,0,1, video::SColor(255,255,255,255), 0, 0);

		Box.reset(Vertices[0].Pos);
		for (s32 i=1; i<4; ++i)
			Box.addInternalPoint(Vertices[i].Pos);
	}

	virtual void OnRegisterSceneNode()
	{
		if (IsVisible)
			SceneManager->registerNodeForRendering(this);

		ISceneNode::OnRegisterSceneNode();
	}

	virtual void render()
	{
		u16 indices[] = { 0,2,1, 2,0,3 };
		video::IVideoDriver* driver = SceneManager->getVideoDriver();

		driver->setMaterial(Material);
		driver->setTransform(video::ETS_WORLD, AbsoluteTransformation);
		driver->drawIndexedTriangleList(&Vertices[0], 4, &indices[0], 2);
	}

	virtual const aabbox3d<f32>& getBoundingBox() const { return Box; }

	virtual u32 getMaterialCount() { return 1; }

	virtual SMaterial& getMaterial(u32 i) { return Material; }
};

Are you placing 2 nodes on top of each other so that you can only see the 1? And can you show some code for placing the node into the scene, so we can see if there is anything there that might be causing issues?

Whoops! This scene node works fine, actually. I wasn't setting the position correctly, so they were indeed all overlapping. It's actually working fine. I've been coding for the last 10 hours straight for a competition, and so I'm prone to making small mistakes. Thanks for looking at it though.

No problem, good luck on your competition!
