Collisions and Joint Constraints

[kmon7485]

Do two bodies connected by a hinge or slider constraint no longer undergo collisions with one another?
e.g If you have two boxes connected by a slider joint and you apply a force such that one box runs into
the other, can you make them collide?

At the moment mine just pass through each other, but once
the joint is disconnected they collide properly

When you add a constraint to the dynamics world, you can specify to enable collisions between connected bodies or not, as second argument:

Code: Select all

virtual void	addConstraint(btTypedConstraint* constraint, bool disableCollisionsBetweenLinkedBodies=false);

Have you tried setting the second argument to 'false' ?
Thanks,

Thank you so much, that has completely fixed my simulation
