using keystroke functions and logic bricks

i got a few questions and if anyone can answer any of them it would be a big help.

#1: how does using the HOLD modifiers in the keystroke logic bricks set up work? it doesn’t seem to do anything for me but this wouldbe very usefull.

#2 : how can i enable certin sets of logic bricks when one paramter is met and disable another set. such as using true’s and false. does blender have anything to do this or do i need to learn python?

#1 - They don’t do anything, at least as far as anybody knows.

#2 - basically makea true/false property or just an integer property, then make 2 property sensor, one when prop = True and one when the prop = False (do this in addition to your other sensors). Now connect the prop = true to each of the controllers that connect to the actuators that you want to enable when prop = True, and then connect the prop = False sensor to the controllers that you watn to enable when prop = False. make sure that the controllers are AND controllers.

You can get and set the hold keys in Python, but you can’t find out if they’re currently being pressed or not :-?

I think it’s a feature that nevery got implimented, so just ignore it. Use two keyboard sensors connected to an and controller instead.
