I am not an expert but ill try to answer your questions :
Q1 : DONT KNOW
Q2 : by making a costum camera, and then you can define speed or change the fps camera source(never did it before).

Q1: See tutorial/example 11.
Q2: Presumably you mean changing the speed of an FPS camera after it has been created. Like MasterM said, you could make a custom one or alter the source of the FPS camera. Alternatively, you could get a copy of the SVN, which uses an FPS Camera scene node animator which you could get a hold of from ISceneNode::getAnimators() and change the speed through.

Well, you can also wait some more days and use Irrlicht 1.5, which will makes those features into an official release

Also instead of making a new topic for such a small thing i'll ask here. Can somebody please explain the parametres of core::rect<s32>(....)

Really?
Code: Select all
rect(T x, T y, T x2, T y2)
: UpperLeftCorner(x,y), LowerRightCorner(x2,y2) {}
rect(const position2d<T>& upperLeft, const position2d<T>& lowerRight)
: UpperLeftCorner(upperLeft), LowerRightCorner(lowerRight) {}
rect(const position2d<T>& pos, const dimension2d<T>& size)
: UpperLeftCorner(pos), LowerRightCorner(pos.X + size.Width, pos.Y + size.Height) {}

Note that the simplest IVideoDriver::draw2DImage() methods just needs a destination position, not a source or destination rectangle.

Ok thanks for the tip, i have another question about 2D images....Trasnparecny. How can i achieve transparency in images. Ive tryed making the image background transparent using
driver->makeColorKeyTexture(crosshair, core::position2d<s32>(0,0));
But that hasnt worked the background just stays black.

you have to give it as a parameter to use alpha channel.
see the drawImage()'s parameters
