Hallo,

I'm an object physic with "ph_hinge" and an other object physic with "ph_slider". The first object and the second object are in phent_setgroup(...,1). With code

"my_slider=phcon_add(PH_SLIDER,my,you);
phcon_setparams1(my_slider,vector(0,0,1),nullvector,nullvector);
phcon_setmotor(second_object,vector(20,10,0),nullvector,nullvector);"

my second objet move in this direction (at down), but i want that my second object changing this direction (at up)... In the manual, it's write that us must changing the direction, but how??

Other, for the chain, i make the balls physics for my chain move with collisions with other objects, but how can i attach the links at my balls physics??

Thanks..
