This script was created so I could use both a flight script and the anti-push script without blatently conflicting. The anti push portion with the flight is truly great. It won't stop people from knocking you out of a sim, but minor pushes and such won't bother you. What's more is if you're not doing anything and you happen to fall for some reason (you were standing high on a platform in cordova or something and someone deletes it), you won't fall very far before the script catches you. It's amazingly convenient. Also knowing just who's bullet smacked into you in your chatlog provides a lot of peace of mind. It could certainly use some improvements though. (as outlined in the known bugs)
Known Bugs:
Releasing controls at this time seems imperfect, I believe I forgot to set locked to false if you're locked and you release controls, thus you stay locked. (easy to fix, but I'm that lazy)
Leaving a sim or entering a sim during extreme time dilation or lag seems to lock you sometimes without taking controls. I have no idea what's going on here.
Flight controls seem to not allow you to descend to the ground at anything other than Walk!. What happens is you kind of bounce at a certain height depending on your speed. I don't have the best grasp of physics, but I imagine someone who does will immediately grasp what's going on here and can either fix it or comment on what's wrong.
The detection script works great except that your own avatar will cause it to set off when you collide with scripted objects on purpose. I have an elevator in particular that set this off constantly. A work around is to check for your own name in the list, but this still won't stop instances of you bumping into other people rather than vice versa. So I really have no idea how to check for that, if you can check for that.
