Several questions on Irrlicht

[specialops 0]

Hi, I am pretty new to this forum and I have some questions on the Irrlicht engine for AutoIt.

First, I get an error when trying to run Irrlicht 2.0 scripts;

D:\Programme\AutoIt3\Include\au3Irrlicht2.au3 (1427) : ==> Subscript used with non-Array variable.:

Return $result[0]

Return $result^ ERROR

This error was mentioned in the original Irrlicht thread but the coder that had this issue does not answer to the message I sent to him.

Then I want to ask if you can change the default movement control keys of a camera - to wasd to move and space to jump.

Next question that I have is how I can make a sphere consist of a solid material; that you can not fly through.

Also, is there a function to find out the xyz position the mouse points at? Tried it over vectors, but failed.

I am not sure if this is the right forum section, please move this thread if I got the wrong one (:

Special_ops.
