multikey keyboard input

Hi,
i've been browsing the forums and I noticed that Irrlicht has a problem with dealing with multiple key presses unless they are simultaneously pressed. Which causes a problem for my game. So I was wondering if anyone knows of a way to fix it or if not what people think the best alternative to use for keyboard input is?

I'm using C++ under Windows if that's any help.

Thanks in advance.

I think you should search the forum for "bool keys" or something like this

There should be no problem detecting when multiple keys are pressed.

When any single key is pressed, you just set a flag indicating that key is down. When a key is released, you clear the flag. If you want to check for key combinations, just check the flags for each key.

In addition, if this isn't a problem with your understanding of Irrlicht, it could be a limitation of your keyboard.
I don't know the exact layout (it probably varies), but only shift/control/alt/win etc have a dedicated wire to themselves, and the others have to share. The result is you can't press more than 3 keys simultanously, and their internal wiring has something to do with it. For example mine supports 'asdf' together, but not 'sdfg', yours may be different.

oh ok, my problem is that i am using a boolean key map and when i am holding a key and then press another key it seems to forget that I am already holding a key. I thought from reading other posts that the problem lies in there being a OnEvent thing that only reads the latest keypress but it may be my code. I'll need to study it better when i get home from work but any further input from the community would be much appreciated. Thanks for the replies so far.

<EDIT>If it helps, i'm having the same problem as the guy here but i'm using C++ and can't really understand whats going on in the C# link to code that is provided there.
