Irrlicht Engine

Solved. I was setting the billboard RELATIVE position to itself off from the center instead of setting the billboard absolute position in the world. So the rotation was completely messed up

Now it rotates as expected.

By the way, this is my render method for the multi-purpose billboard (static and ...

Someone else will have to answer this as I have no experience using texture matrices. However, I believe that Irrlicht actually passes texture matrices to the driver, so you might just try it.


How odd that it's not supported by default then. I already have my animations and billboards working as ...

Thanks! I didn't know that. I'll test it ASAP.

About the billboards:
I implemented my own billboards and texture animations. My billboards have an option to face the camera, or simply not. Now that you mention it... would simple planes accept texture animators? It's not that it took me much time ...

Suppose I have two boxes, the world around is moving and rotating, but the two boxes must stay at a fixed point relatives to each other.

Is there any way to do this?

The truth is I have 4 billboards which should act as a box, rotating and moving around. But it must look like it's only one object ...

looks like it's too late and I'm a newbie myself, so I don't know if this helps, but you can use the code from the Example N°8: Special Effects.

// create light

node = smgr->addLightSceneNode(0, core::vector3df(0,0,0),
video::SColorf(1.0f, 0.6f, 0.7f, 1.0f), 800.0f);
scene::ISceneNodeAnimator ...

I solved it. I updated the first post with the result. It's the first thing I do with irrlicht, so there might be some errors in the code.

Thank you Ovan. I learned that the hard way through experimenting, but I just started assuming a lot of things, without being sure about anything (I edited the original thread about an hour ago). Now it's clear.

here is the debug output and object information about the SceneManager


p irrSceneMgr
$1 = (irr::scene::CSceneManager *) 0x10b1bc0

type = /* real type = irr::scene::CSceneManager * */
class irr::scene::ISceneManager : public virtual irr::IReferenceCounted {

I'm trying to re-implement the billboard with a minor changes and I'm experiencing this behavior:
When CSceneManager calls the constructor of the billboard in addBillboardSceneNode, the ISceneNode calls parent->addChild... where the parent is the CSceneManager object in memory.
For a few extra ...

Since I'm just a newbie on these, I ended up trying the TAnimSprite. It does what I need, but could you guys point me to the right direction when it comes to rotating and moving the ISceneNode? (moving it would be the most important)

AFAIK, the demo and 2D tutorial in irrlicht only covers basic 2D drawing on the screen. What I actually want is a billboard with a texture animator, that doesn't point at the camera all the time (I know it sounds weird), and it's efficient enough to show a lot of "sprites" on the screen ...

UPDATE:
I don't know if it's the best way to do it, but I implemented a few classes that work just fine. Here is the irrlicht example:
