thanks,

Besides this line?

sphere->setMaterialTexture( 0, driver->getTexture("graph.jpg"));

The image does show on the sphere no problem. Is there something else I need to add for the texture? Is there transparency alpha for the texture itself?

Oh come on - try a little bit before asking each step. Try using 0 again for example instead of 255. I tried 0 or 255 but no luck. Am I missing some other mesh material methods? scene::IMesh* sphere_mesh = sphere->getMesh(); scene::IMeshBuffer* sphere_mesh_buffer = sphere_mesh->getMeshBuffer(...

IMesh (which you got from getMes()) has functions to access the meshbuffers. That node will only have one so you just need to access the first one. I think I have it right but still no transparency :? #include <irrlicht.h> using namespace irr; class MyEventReceiver : public IEventReceiver { pub...

Code: Select all

Meshbuffer->Material.DiffuseColor.setAlpha( (s32)(value * 255) );
Meshbuffer->Material.MaterialType = video::EMT_TRANSPARENT_VERTEX_ALPHA;

Sorry for my ignorance but how do I turn my sphere of IMeshSceneNode into a Meshbuffer?

There's a post by an author call feelthat. I saw a few weeks back, he did transparent even for animated mesh. I think he fixed other issues he found as well. Actually there's also lot of posts on the related issue if you search the forum. http://irrlicht.sourceforge.net/forum/viewtopic.php?t=31400 ...

Hm, I really have to sleep, so won't test now. But I suppose it's because the material used in the mesh is solid. Try using any material supporting transparence like video::EMT_TRANSPARENT_ADD_COLOR. Goodnite, thanks so far though, this code below works now except that the texture cannot be alpha b...

Here's the complete code #include <irrlicht.h> using namespace irr; class MyEventReceiver : public IEventReceiver { public: struct SMouseState { core::position2di Position; bool LeftButtonDown; SMouseState() : LeftButtonDown(false) { } } MouseState; ...

IMeshSceneNode is derived from ISceneNode, meaning it has everything ISceneNode has + some additional stuff. That's why you can always cast safely to the base-classes. Not sure right now if the alpha value means transparence or opaque, doesn't seem to be documented. Just try it with 255 maybe. Trie...

Well, then take a look at the documentation which type addSphereSceneNode does return: http://irrlicht.sourceforge.net/docu/classirr_1_1scene_1_1_i_scene_manager.html#acd6454347276ff8c74e46063970cfc04 Maybe you are lucky and it's real type does have such a function ;-) It returns a type IMeshSceneN...

Use sphere->getMesh() to get the mesh. Tried but got this error. scene::ISceneNode* sphere = smgr->addSphereSceneNode(radius, 32, 0, -1, core::vector3df(0, 0, 0), core::vector3df(0, 0, 0), core::vector3df(1.0f, 1.0f, 1.0f)); sphere->setMaterialFlag(video::EMF_LIGHTING, false); sphere->set...

You can try to experiment with IMeshManipulator::setVertexColorAlpha. As each sphere-node has it's own mesh that should work. Thanks so far, I tried this scene::IMeshManipulator* mesh = smgr->getMeshManipulator(); mesh->setVertexColorAlpha(sphere, 0); But the compiler complains that my sphere isn't...

Hi All, Sorry for asking such a noobish question considering that this has probably been answered before but I did search and found very little on how to do it, including this page http://irrlicht.sourcearchive.com/documentation/1.7.2plus-pdfsg1-1/ISceneNode_8h_source.html Anyways I have this code w...

I only use it to get the time. Time is time... short of creating another universe I can't do much about that :-) The difference it that this one can be started/stopped independent of each other. But if you have only a single instance of ITimer and used one of the methods in the Timer wrapper you ca...

CuteAlien wrote:Yeah, it looks similar to ITimer as it's basically a wrapper around it. And yes - that's the pointer you pass.

But isn't that the same instance of the ITimer which implies that you would still have one timer for each Irrlicht device?

pandoragami

So much for the theory. But you likely don't need that. You can't pass a timer back to Irrlicht so deriving from that is probably useless. If you need a timer then either write your own class - or use the a pointer to the Irrlicht timer in your class (here's an example where I do that: http://www.m...
