I know that it's possible to move the whole IParticleSystemSceneNode, but that affects the position of the emitter AND all particles that are already on screen. I tried setting a box emitter in every frame and changing the coords, but it worked rather... weird. So, is it possible in Irrlicht to move only the emitter? I need it for effects such like a fireball leaving a trail of particles behind it, etc.
yes it's a known problem of standard irrlicht system particle, I wrote a patch to it and you can find it in irrlichtnx, just have a look in the "open discussion" forum and search about system particle you'll find here the patch
