How do you delete a joint?

[johnsonalpha]

if i do this

Code: Select all

 p2p =newbtPoint2PointConstraint(body1,body2.b1trans,b2trans);

how can i delete this now

If you already add the constraint to the dynamic world, then you can use:

world->removeConstraint(yourConstraint);

Is there a way to loop through all joints and delete them?

Not directly, though it would be easy enough to add such a method to btDiscreteDynamicsWorld, or to expose it's constraints list if you wanted to :

btDiscreteDynamicsWorld.h

btAlignedObjectArray<btTypedConstraint*> m_constraints;

[johnsonalpha]

can you help me how would i write that im really stupid

[johnsonalpha]

is it like this btAlignedObjectArray p2p* m_constraints;

btDynamicsWorld has getConstraint:

Code: Select all

for(int i=0; i < world->getNumConstraints(); i++)
{
	btTypedConstraint* constraint = world->getConstraint(i);
	...
}

To remove all constraints:

Code: Select all

for (int i=m_dynamicsWorld->getNumConstraints()-1; i>=0; i--)
{
	btTypedConstraint* constraint = world->getConstraint(i);
	world->removeConstraint(constraint);
	delete constraint;
}
