Been looking through the Wiki http://www.creationkit.com/DisablePlayerControls and seeing if I can disable jump only. Seems that it comes under movement and I need the player to move. Anybody ever succeeded or even tried this? Maybe the only way is a collision plane as a "ceiling".

I wanted to setup a corridor where the player had to crouch (sneak) to pass because of a low ceiling, because of actor collision I had to take collision off the nifs that acted as the ceiling but it could be ruined if the player jumped.

I was disappointed not to find a way of disabling jumping, something that was suggested at the time was that SKSE might have worked by checking for the keystroke but I don't know if that's any help.

The only option I have found is a collision box or plane. Its crude and if in my case the ground level goes up and down more than 1 box, each tailored to that specific ground level's section is needed. Tedious and tiresome but only way I know. Thanks.
