Irrlicht Engine

Two quick questions

Firstly, no matter what i do, i cannot seem to have any gui elements after i've loaded an irr scene. i would like to have some buttons overlaying the irr scene, but they just dont show when i run the scene.

Secondly, After i used Fadein();, my GUI elements (buttons etc) appear frozen.. any ideas?

thansk guys!

You have to draw the GUI environment, not just the scene manager.
What is Fadein? Maybe there's a focus problem, or your event receiver does not get the events?

Ok i fixed the first problem, the gui was drawn too early. i put guienv->draw after smgr-> draw and it was fine.

FadeIn is part of the gui. i dunno why it freezes the gui, but the even reciver works fine before i call fadeIn.

Also, when i do:
smgr->getActiveCamera()->setInputReceiverEnabled(false);

and then:
smgr->getActiveCamera()->setInputReceiverEnabled(true);

my app crashes.. any ideas why?

thanks all.

Well, you did not say which object you called fadein with, that's why I asked. Crashes are usually due to corrupted pointers, but we'd have to see code to check this. Or you use a Debugger
