Code:

var LF_DOOR_ID;

action lf_door
{
	phent_settype(my,PH_RIGID,PH_POLY);
	
	ph_setgravity(vector(0,0,-800));
	phent_setgroup(my,2);
	phent_setmass(my,50,PH_BOX);	
	phent_setfriction(my,15);
	phent_setelasticity(my,5,5);
	
	LF_DOOR_ID = phcon_add(PH_HINGE, *change to hinge*, my);
	phcon_setparams1(LF_DOOR_ID, my.x, vector(0,0,1), vector(0,1,0));
	phcon_setparams2(LF_DOOR_ID, vector(0,70,0), nullvector, vector(0,0,0));
}

ok, this is a real old code of mine, not sure if it still works.
you'll have to see for yourself, good luck!
