How to make a fixed joint?

[spiritkay2010]

I use btHingeContraint, and already setLimit(0,0).
But the hinge is not secure.
How to make joints are not affected by gravity, not bent? I want the fixed joint!!!:(

You can try making the object a static one instead of dynamic, then it shouldn't be affected by gravity, and you
can still have it as a hinge

Have you made any progress on this? I am interested in this, too. I can't use the suggested fix (make one static) because I need to "glue" two dynamic objects together.

Thanks.

The best way to create a fixed joint is using the btGeneric6DofConstraint, and set all upper a lower limits to zero.
