It just works with inkey I guess.
It's just that I tried it out and then the engine crashes.
I looked at the manual too and there it just says,
inkey_active terminates the input with inkey...
Well, and that was just a reading-fail again. -.o'
So it looked clear for me, inkey_active isn't the right solution for that.
Well, but if you say, it should work with inkey_active,
then it's maybe another fault in my code and I'll try it out more exactly.
Thank you.
