Irrlicht Engine

Hello All -

I have a bunch of nodes what have been added with the following call:

nodeptr = SMGR->addCubeSceneNode(size)

I was wondering if it's possible to change the size of the cube dynamically in the code? I can change scale but I believe that means my options are x1 as big, x2 as big, etc ...

Hazzah! That wasn't as hard as I thought it would be. This is a waypoint animator that moves a node through several points. It's not constant speed but at least it only slows when changing angle, not when moving in a straight line through points like a spline animator.

The animator destroys itself ...

In case anyone else uses the functions supplied by vitek above.


// in your animator...
if (m_finished)
ISceneNodeAnimator_addToDeletionQueue(mp_sceneNode, this);


But it should be:


// in your animator...
if (m_finished)
ISceneNodeAnimator_addToDeletionQueue(this, mp_sceneNode);


The ...

So far I'm having a really interesting conversation with myself ;)

I now believe a custom scene animator is the way to go here. The animator should accept an array of points to move through in a waypath sort of way and it should either loop when it reaches the final point or delete itself based on ...

Or better idea - is there a way to chain createFlyStraightAnimators() so that one the node flys straight to the first point, then straight to the second and so on?

I've had a think about this problem. createFollowSplineAnimator() follows a spline which by its nature tends to be curved and curves mean slowing the node as it moves.

But the way I want to use it is to propel nodes in straight lines with occasional branches off. I use a tightness value of 0 ...

Hello All -

I'm moving nodes around using createFollowSplineAnimator(), some splines have only a few points, other splines have dozens of points. The nodes slow down at each spline point rather than staying at a constant speed.

Can anyone tell me if it's possible to set createFollowSplineAnimator ...

Hello All -

I seek the wisdom of the Irrlicht oracles... again ;]

My app draws a straight line linking 2 points in 3D space. But I need to dynamically find X number of points along that line (preferably equally spaced along the line). I have tried several different approaches but without much ...

Hello All -

In my app, I have nodes drawn randomly throughout the 3D space and I have setup a FPS camera to let the user move around the space. I've recently added code that detects a double click. If the user double clicks on a node I wanted the camera to jump forward in that direction.

Here is ...

I would love to see azureus' 2d version.

Thanks for the optimization advice, I'll start searching the forums for ideas.

Thanks guys for the kind words.

There is a 'demo mode' which moves the camera fly through the environment on an endless loop. Its like a screensaver mode I suppose. You can access it by hitting the 'D' key. Of course if you want to just move around the environment yourself using your mouse and ...

Hey guys,

My last question I promise - one of my beta testers is getting the following error on their console window. Can anyone tell me what it means?

Irrlicht Engine version 1.3
Microsoft Windows XP Personal Service Pack 1 (Build 2600)
Using renderer: Direct3D 8.1
NVIDIA GeForce 6200SE ...

Thanks vitek - that worked a treat. You're the man! ;]

I knew it would be something stupidly simple. I had no idea I had to remove a node's triangle selector from the meta selector. The irrlicht tutorials are great but they don't really give you a background in 3D development which would have ...

I hope nobody minds me reigniting this thread but I have some more information which hopefully will lead to a fix.

I recompiled the Irrlicht DLL in debug mode so that I could walk the call stack when it crashes. The stack is as follows:


main()
CSceneManager::drawAll()
ISceneNode::OnAnimate ...
