the node phys_slideconstraint is causing trouble after compiling.
The map crashes and do not load at all.
There is a phys_pulleycontraint for two func_physboxes (weight and counter-weight)
And there is a phys_contraintsystem of course.
Without phys_slideconstraint it's working quiet well.
BUT:
I like to keep a func_physbox upright.
It should only move up and down, any rotation should be limited.
I already tried "phys_keepupright", but it didn't work very well.
The best of that: it doesn't cause crashes.
The func_physbox is now in a cage of func_clip_vphysic,
but it still tilts and rolls, when other weight-forces affect it.
Any Ideas?
Thanks for any help.
