BtPoint2PointConstraint do more rigid

[lcarames]

Hello, everyone walk like, well I wanted to make a query. I'm using this type of union: btPoint2PointConstraint among others. The problem is that such unions are too soft or me with a lot of freedom. I need that this union is rigid as steel and is not flexible. How can I do to tighten these joints? Thank you all for your time, greetings ...

To get the hard joints / constraints you want it might be better to keep both (ex. meshes) inside a single rigid body and describe their geometry using a compound shape together with multiple shapes (ex. boxes). It of course depends on if you want to only use the constraints to keep the bodies together.

Thanks for your answer, but what I'm looking for is a tie to a wheel of a car chassis that is, a union has to be fixed and the other has to rotate.
